@@heisenburgfreed7591 could just do and current_user.image_file != 'default.jpg': either one works. Yours kinda keeps it more consistent with the os.path thing Thanks OP. Was struggling with this before this comment.
loving this tutorial! i added the code to delete the old profile pic when updating with a new one. this is the if statement in the account function in routes.py ``` if form.picture.data: old_pic = current_user.image_file picture_file = save_picture(form.picture.data) current_user.image_file = picture_file if old_pic != 'default.jpg': os.remove(os.path.join(app.root_path, 'static/profile_pics', old_pic)) ```

Can anyone clarify if the profile picture is being fetched from the server or from the local filesystem (when GET request is called on the account page)? To me it seems like while the file name is sent to the SQL database, the actual image isn't being sent to the database at all?
@@xtrzne A little late, but I'll answer for those who wonder. After a picture is selected from a local file system on the webpage, it's being put (its resized copy) onto the local filesystem *by the server* (which is now being run locally) into *static/profile_pics* directory. Only the filename goes into the database. It's often a bad thing to store bitmaps in the database as blobs.
Duuuuuuuuuuuude, you're a beeeaaaaaaaaaast ! Your tutorials are awesome ! keep the good work ! If you could put a series about Laravel that would be dope ! You got some high quality skills in teaching ! Thanks a lot !

I have no experience using any backend framework, except some basic django... I did not expect such an amazing quality from a TH-cam tutorial, which is free! thankyou! this is an amazing series! you're god sent for broke students!
In order to make the picture upload work on the current version of Python and Flask, in "forms.py" I had to change: [code] picture = FileField('Update profile picture', validators=[FileAllowed('jpg', 'png')]) [/code] to: [code] picture = FileField('image', validators=[FileRequired(), FileAllowed(['jpg', 'png'], 'Images only!')]) [/code] Last but not least, thank you for the great series!
I think you only had a problem because you forgot to put the file types into a list. [FileAllowed('jpg', 'png')]) should have been [FileAllowed(['jpg', 'png'])]). He had the brackets correct in the video and it worked for me on the newest version. When I was following along I wasnt expecting to have to use the list, so I'm guessing you thought the same and didn't notice him do it.
Corey, Your python videos are really amazing. I started python programming after a decade and I'm into it now. But my job is mostly in automation testing. Wanted to change to development and picked your series. Can't stop in btw, yesterday I started and now I'm in part 7. With this video reference, I can able to build the website. Amazing Work!!
Another LEGENDARY vid! When I saw you install Pillow, I thought to myself "Python is like the car, and these extensions are like aftermarket parts... " :)
Hello, my name is Pedro and I live in São Paulo, I am writing this text to thank you immensely because you are not only helping me in my professional life but also in my academic life. Keep being this amazing person that you are and may there be others like you over the years, thank you very much.
For the profile picture @21:57 , I had to change picture = FileField( 'Update Profile Picture', validators= [ FileAllowed ( [ 'jpg', 'png' ] ) ] ) to picture = FileField( 'Update Profile Picture', validators=[ FileRequired(), FileAllowed ( [ 'jpg', 'png' ] ) ] ) and also import FileRequired at the starting of the file. maybe because I'm using Python3.5 and not 3.6 Thanks for the awesome tutorials @CoreySchafer
as a zero knowledge person about coding, i wonder how did I able to go this far in the series(Part 8) and be able to successfully roll out the apps. Thank you for these videos. I am very excited finishing this apps.
Just fyi, this video used picture_path = os.path.join(app.root_path + "static/profile_pics" + picture_fn) Corey is using mac, and it works for him, but for people using windows please use: picture_path = os.path.join(app.root_path + r"\static\profile_pics\\" + picture_fn)
Thanks for catching that! I think the best solution is to simply pass in static and profile_pics as different arguments like so... picture_path = os.path.join(app.root_path, "static", "profile_pics", picture_fn) I will issue a correction in the next video I add to this series. Thanks again!
Yup, join should take care of that. Thanks for these tutorials Corey. Really appreciate em. I am not as fast as the other guys, who finished these tutorials in a day or two. I am on week two. :)
This videos are amazing and complete, support this channel is a must! Just a question for the audience, to see if someone is having the same problem: - On the account route, when updating the current_user.name and current_user.email with the form data, then doing the db.session.commit() is not updating the DB but the commit returns None as if everything was Ok, has somebody run into the same problem?? Thank you very much again!
29:00 - Even though the likelihood of two 8-byte numbers being the same is astronomical, might as well check to make sure the image doesn't already exist and if so, regenerate a new hex.
Ha! When I got to that part I thought the same thing and immediately checked the comments to see if anyone else did too... Agree that it's incredibly unlikely, but better safe than sorry.
@@BtheDUB Actually you would probably have to check the profile_pics folder with the os.listdir() function and compare them to generated hex. If the file already exists, regenerate new hex. But as been told, that's not very likely.
For those wondering how to remove the previous image from the profile_pics directory after updating the profile picture. It's just as simple as adding this line in the save_picture() function: - if current_user.image_file != 'default.jpg: os.remove(os.path.join(app.root_path, 'static/profile_pics', current_user.image_file)) It has be added before this line: - i.save(picture_path) Let me know if someone find another solution!
Hi Corey, not sure if you're still reading these comments. Loving the tutorials. Am up to the end of this video. Pillow is installed for PIP. Run the code and I get the following error. website_1 | File "/logrr/logrr/blueprints/login/views.py", line 74, in accountPage website_1 | picture_file = save_picture(form.picture.data) website_1 | File "/logrr/logrr/blueprints/login/views.py", line 57, in save_picture website_1 | i.save(picture_path) website_1 | File "/usr/local/lib/python3.7/site-packages/PIL/Image.py", line 2004, in save website_1 | fp = builtins.open(filename, "w+b") website_1 | FileNotFoundError: [Errno 2] No such file or directory: '/logrr/static/images/profile_pics/757b0bf5ed6b98cb.jpg' I check and sure enough, in the profile_pics folder there is no file.

Line 74 is calling the save function: picture_file = save_picture(form.picture.data) Line 57 is the actual save line in the function: i.save(picture_path) What could be wrong? I'm a little stumped. Thank you
Now I solved. Problem is this: when we delete the first section of the file, we also delete the name of uploading* object. However, we need it. File we download has also hex-like naming. In fact, we need first and second section of life. My solution for this deactivate the random_hex. In this way, I was able to upload it. However, I am not sure, what kind of security issue it can cause. f_first, f_ext = os.path.splitext(form_picture.filename) picture_fn = f_first + f_ext With this, I am able to upload a new picture.
Hi, I need help with forms please. In the home page, I'm trying to add a capability for users to add comments for each post without going to a different page. Since each comment would belong to a specific post, I need to pass the post's id from the HTML back to the route function in Python along with the actual content of the comment so I could save it in my DB. passing the title of the comment is no problem, you just render wtform field with jinja2 and then the user fills it up (as Corey shows) but how do create add a dynamic value for the form while inside the HTML? I've tried with jinja2: {% set form.post_id.data = 'whatever' %} but got jinja2.exceptions.TemplateSyntaxError: expected token 'end of statement block', got '.'
Hi Corey, Excellent video, this was extremely helpful! Can you add a quick video to show us how we can add pictures and video files to each post? I would like the user to have the ability to include photos from their desktop and add to their posts. I love that they can add photos to their profile and would like to provide the option for them to include photos within their posts as well. Thanks so much!!
Something that I noticed is Emails are NOT case sensitive and that should be taken into account when making a website that requires email or else people can sign up for multiple account using same email by changing capitalization their email.
Wow, thank you for these great videos! I mostly program as a hobby, and have had trouble finding good resources on web development, and was honestly quite intimidated, but you, as always, provide a great series! I have a question about the render_template() function: what determines whether or not you need to pass a variable to it? For example, `title` and `image_file` are passed in, but current_user isn’t, but still works fine in the template. Thank you again!
These are all optional parameters and are autoscaled into the function as context variables. The only required parameter is the resource template which is our actual html. The rest can be left out and can be either made use of or ignored. render template is coded to be as flexible as possible hence the use of autoscaping here (**). Its why that one function works for, taking in as many parameters as needed without needing restructuring of the function.
At about 28:22 Corey mentioned that the Secrets module has been used earlier in the series, but I'm totally blanking on that. Can anyone be a bro and let me know which video and rough time that was?
I really love the series and am really having fun, I just have one question on this module though...I thought we will be sending the images the users upload to the database, why are we sending them to the static folder? Is this how real world web apps work, or is there a way to send these images to a database.? Otherwise, am moving to the next module, and that is the one for creating, updating and deleting posts, Pure fun
Decided on Part 3 when I noticed all the repeated/copy and pasted code in the register.html, especially after putting in the if errors code I was going to keep it DRY and find a better way. Now after doing the account form as well I have made it really cleanly. In register.html, login.html, account.html in place of ...... I just put {% include 'includes/_form.html' %} Then I made a includes/_form.html: {{ form.hidden_tag() }} {{ form_title }}
I really love your tutorials. This series specially helps me a lot. But man ... i usually play tuts with 1.25 even as non native english speaker .. but you are that fast o0
Hello Sir, I have a question for you. You have a great experience with python and flask before creating this playlist, I want to know your approach on this topic. Before creating this project in this playlist, how much time did you take to get this fluency in the flask model? How many projects do you recommend I to create and build to get this kind of fluency. Your answer will motivate me. Great content by the way, I am learning a lot from you. Thank you for your effort on this.
There is a problem if we have more than one account in the system. I was having an issue where I was uploading a picture to my profile but it was displaying the same picture uploaded to all users. The problem was that I was passing the variable image_file to the template set to current_user, like this: "image_file = url_for( 'static', filename='img/profile/' + current_user.image_file)" To solve it I added to my route so I could get the user id from the navbar (I had to add a variable "user_id=current_user.id" in my layout.html). I passed the parameter called "user_id" into the "account" function and defined a "user" variable then I used this "user" instead of "current_user" in the "image_file". However, I also had to pass "user_id=current_user.id" back when I redirected the page, like so: layout.html Account routes "@app.route("/account//", methods=["GET", "POST"]) def account(user_id): user = User.query.filter_by(id=user_id).first_or_404() .... ..... return redirect(url_for("account", user_id=current_user.id)) image_file = url_for( 'static', filename='img/profile/' + user.image_file)" In case anyone runs into this problem.
great video, really helped me understand some cool tricks with flask. Corey, i was wondering if you could give an example of how to remove the image files from the file directory upon updating profile picture. Thanks again
Once again, every video is excellent. Thank you for your effort and offering to rest of us. Few questions: - I am planning to use Google App Engine + Python 3 + Flask. Will this work? - Also, i want to use GCP's datastore and upcoming firestore. Since we are using sqlalchemy, will it work out of box? - do you have similar example of using Firebase's user authentication.
Hey Corey! The update picture thing is not working nowadays... I suppose the python version changed and something got messed up. Do you or anyone else care to help beginner debuggers to get these features up and running again? :D thanks a lot :D
Really very nice tutorials Corey. Went through all your videos Django, Flask . Thank you. Hope you would reply my question: How you will know that you need that form or anything to imported if it’s by going through documentation how you manage to go through all the content because one page leads to many sub topics? I really wish you could reply or make a video on this . Thank you once again 😊.
Love these videos, easy to follow and of just the right length. :) Have a question tho... when I upload a .jpg the orientation changes, is it possible to add some code to prevent that?

I would like the user to have the ability to include photos from their desktop and add to their posts. I love that they can add photos to their profile and would like to provide the option for them to include photos within their posts as well. Thanks so much!!
thank you so much sir you are the best i think this channel is the best , really great content
Something that I noticed is Emails are NOT case sensitive and that should be taken into account when making a website that requires email or else people can sign up for multiple account using same email by changing capitalization their email.
I did exactly what you did on tutorial but even after uploading the picture it doesn't appear on the account page
Amazing tutorial.. thank you for your efforts
Wow, thank you for these great videos! I mostly program as a hobby, and have had trouble finding good resources on web development, and was honestly quite intimidated, but you, as always, provide a great series!
I have a question about the render_template() function: what determines whether or not you need to pass a variable to it? For example, `title` and `image_file` are passed in, but current_user isn’t, but still works fine in the template.
Thank you again!
These are all optional parameters and are autoscaled into the function as context variables. The only required parameter is the resource template which is our actual html. The rest can be left out and can be either made use of or ignored. render template is coded to be as flexible as possible hence the use of autoscaping here (**). Its why that one function works for, taking in as many parameters as needed without needing restructuring of the function.
great work, amazing help.
Great videos! Thank you very much!
At about 28:22 Corey mentioned that the Secrets module has been used earlier in the series, but I'm totally blanking on that. Can anyone be a bro and let me know which video and rough time that was?
It was in Part 3 at about 11:00 minutes. We used it to generate a random string of characters for our secret key.
While your puppy picture was on I heard nothing you said :D In my mind only "AAAWWWWWW, CUUUUTTTEEE"!
Your videos are magical
very nice Corey !
I really love the series and am really having fun, I just have one question on this module though...I thought we will be sending the images the users upload to the database, why are we sending them to the static folder? Is this how real world web apps work, or is there a way to send these images to a database.?
Otherwise, am moving to the next module, and that is the one for creating, updating and deleting posts, Pure fun
Decided on Part 3 when I noticed all the repeated/copy and pasted code in the register.html, especially after putting in the if errors code I was going to keep it DRY and find a better way. Now after doing the account form as well I have made it really cleanly.
In register.html, login.html, account.html in place of ...... I just put {% include 'includes/_form.html' %}
Then I made a includes/_form.html:
{{ form.hidden_tag() }}
{{ form_title }}
@13:35, we can use `ctrl+shift+;` to delete the html tag in sublime
I really love your tutorials. This series specially helps me a lot. But man ... i usually play tuts with 1.25 even as non native english speaker .. but you are that fast o0
Talented Corey Thanku
I am having some errors in the save_picture() part
Same
Hello Sir,
I have a question for you. You have a great experience with python and flask before creating this playlist, I want to know your approach on this topic. Before creating this project in this playlist, how much time did you take to get this fluency in the flask model? How many projects do you recommend I to create and build to get this kind of fluency. Your answer will motivate me.
Great content by the way, I am learning a lot from you. Thank you for your effort on this.
There is a problem if we have more than one account in the system.
I was having an issue where I was uploading a picture to my profile but it was displaying the same picture uploaded to all users. The problem was that I was passing the variable image_file to the template set to current_user, like this:
"image_file = url_for(
'static', filename='img/profile/' + current_user.image_file)"
To solve it I added to my route so I could get the user id from the navbar (I had to add a variable "user_id=current_user.id" in my layout.html). I passed the parameter called "user_id" into the "account" function and defined a "user" variable then I used this "user" instead of "current_user" in the "image_file". However, I also had to pass "user_id=current_user.id" back when I redirected the page, like so:
layout.html
Account
routes
"@app.route("/account//", methods=["GET", "POST"])
def account(user_id):
user = User.query.filter_by(id=user_id).first_or_404()
....
.....
return redirect(url_for("account", user_id=current_user.id))
image_file = url_for(
'static', filename='img/profile/' + user.image_file)"
In case anyone runs into this problem.
great video, really helped me understand some cool tricks with flask. Corey, i was wondering if you could give an example of how to remove the image files from the file directory upon updating profile picture. Thanks again
Your dog is lovely!
Thank you
@Corey
I dont think that current_user.username = form.username.data
Changes value in database
And i think that the reason why my code isn't working
The ValidationError message is not showing in my one. Can somebody help please?
Once again, every video is excellent. Thank you for your effort and offering to rest of us. Few questions:
- I am planning to use Google App Engine + Python 3 + Flask. Will this work?
- Also, i want to use GCP's datastore and upcoming firestore. Since we are using sqlalchemy, will it work out of box?
- do you have similar example of using Firebase's user authentication.
Amazing. Thank you so much!
Hey Corey! The update picture thing is not working nowadays... I suppose the python version changed and something got messed up. Do you or anyone else care to help beginner debuggers to get these features up and running again? :D thanks a lot :D
Hey there!! have you found the solution?? I'm a beginner too..
I just finished the tutorial works fine on my side. what is the error message?
your puppy is beautiful
impressive and analogical.....
Really very nice tutorials Corey. Went through all your videos Django, Flask . Thank you. Hope you would reply my question:
How you will know that you need that form or anything to imported if it’s by going through documentation how you manage to go through all the content because one page leads to many sub topics? I really wish you could reply or make a video on this . Thank you once
again 😊.
This Videos Really make Programming easy. Thanks Corey for the great content. Do you have a Link of the Django version of this content
Would it be possible to style the "choose file" button to match the theme? Now all the block is clickable. Thanks!
Love these videos, easy to follow and of just the right length. :) Have a question tho... when I upload a .jpg the orientation changes, is it possible to add some code to prevent that?
