In this django forms tutorial for beginners, you will learn how to perform common tasks with django forms.
Django forms can be used for a variety of things, such as generating the HTML form markup or validating a form.
A django form is just a class that contains fields that specify a widget, which is used for telling python which HTML tag you want to generate for this particular field.
By the end of this video, you will have a good overview of how to use django crispy forms to make working with forms easier, how to use ModelForms and we'll also cover an interesting field called the MultiValueField and use it to create our own field.

When I set up the RegexValidator for entering only letters in the name field the message that say "enter a valid first name" shows up when there is only numbers in the field but when there is a combination of letters, such as "james1" , the message doesn't appear and the name is submitted. Is there a way to not allow any numbers at all?
O melhor do youtube, claro como a água.
obrigado!
That's wonderful explanation. I am subscribing to it. Do you have any video to write and read from CSV files using Python in Django ? I use Sublime as Editor in Windows 10.

The Dumbfounds
What will be the next video about??
Srikant It will be either about REST APIs or how to extend the user model ;)
Hey Garbriel, what if my page contains two or more forms! How do I let the view know that I'm submitting data from a particular form?
Hey Srikant, there are a couple of approaches. You can use different actions on the forms and handle them in different views. Another approach would be to assign names to the input buttons to determine which one was clicked. You can find more info on that approach here: stackoverflow.com/questions/866272/how-can-i-build-multiple-submit-buttons-django-form

Great video. But can you also try to explain the django models CRUD? Might be helpful
Thanks! Do you mean what CRUD is in general and how to apply it do Django?

you are wonderful dude thanks soo much...
At 7:34 it shows me TypeError at /
context must be a dict rather than set.
What did I done wrong? And I am sure I wrote the same code in the video.
I am getting an error 19:10 minutes, it is saying
Failed lookup for key [helper] in
During handling of the above exception ("Key 'helper' not found in 'SnippetForm'. Choices are: body, name."), another exception occurred:
It only works after removing form.helper in your line 12, what should I do please help?
Hi there is an issue at the end of the video, I'm not able to switch to snippet page it says an error VariableDoesNotExist at /snippet
Failed lookup for key [helper] in
Specify the snippet as "snippet one" and the body as, I don't know, "nnsjsjsn" 😂😂😂
What if you want a form where the user enters couple of values you have to multiple with a standard value from the table and display it in the same form.
example:
The user has two inputs
1. Pick a category A,B,C
2.Enter a number.
In the back end the database has these values
A=2
B=4
C=6
Our goal is to print what is received in 1 and multiple by 2 and display it in a separate line
------------------------------------------------------------
Example 1
1. User enters A
2. User enters 10
the output should be 20
Can this be done using Django?
Thank you
Krish Kk Sure! Just create a normal form. One input is a choicefield. You can specify the choices as tuples with A and 2, B and 4, and C and 6. The second input would be an IntegerField (in the case that you only want to be able to multiply by who numbers). Then, just process the form, get the two values out of it, multiply and you‘re done :) Was that understandable?
Oh, and as far as the displaying goes: either do it via AJAX if you want it without reloading the page, or just pass it in your context when rendering the template.

Please upload videos on slug field and signals
I do plan a video on identifiers (slug, uuid). Don't know about signals, yet.

Hey Gabriel - Great tutorial! I haven't checked your GitHub page, but is the code for this available?
Hi William. Yes, here is the link to the repo: github.com/Rechunk/django-forms-tutorial
Why did you create 2 classes in forms.py with separated information? I want to have everything in one class
Thanks so much for this video but could you do a video that covers using a GET request instead of POST using Django forms? All of the examples I can find online including this one only cover POST.
why did you want a GET?
Awesome! Please, putting action page later.
Shahidul Bari What do you mean by that?
I want to see in HTML page of my input in a form.
Hello. When I import forms in view I get circullar import error. how can i fix it?
What if you wanted to use a bootstrap options form ... how can you postback the elected options and have Django pick it up using requests.POST ? ... I want to be able to do this without using modals.
NETFQ - Gameplay then don't subclass from ModelForm, only from Form. Does this help? docs.djangoproject.com/en/2.0/ref/forms/widgets/#setting-arguments-for-widgets
thanks .. still not sure how you do it though.. I want to use this: getbootstrap.com/docs/4.0/components/list-group/ ... the 'list' to sent to the template and auto generated via a {% for x in y %} loop ... javascript lets you then select multiple items from the list ... just need to know how to get the selected (active) items from the list back to the view?
basically the multiselect list is dynamic, variable number of items which users can select.
Take a look at the second answer of this: stackoverflow.com/questions/15393134/django-how-can-i-create-a-multiple-select-form. Instead of rendering the form with crispy forms, you can also just type out the html manually. Just make sure to assign a name to your inputs. If that doesn't solve your problem, I'll try to resemble it tomorrow and send it your way.
ok last question I promise :)
How can I populate OPTIONS var with the list of items? How can I pass this list to the form class?
how to design it
Can I use crispy forms with ModelForm? Because I tried as you in the video and there are problems.
Yep, crispy forms does work with ModelForms.
Hi sir, Is this some kind of alternative way of creating forms? can i still create the form in html and use it in my template and expects the same result ? Thanks
Sure, the end result always has to be form HTML the user can use. You can skip the crispy forms part if you want and write raw HTML and CSS. I'll soon have a video up on customizing forms! :)
@@thedumbfounds767 thanks... looking forward on that 😃. im learning a lot from your videos.
@@kenjohnsiosan9707 that's great to hear!
Hello, nice tutorial but I got this error Failed lookup for key [helper] in
same problem. Have you solved it?
@@soumi7356 No, I have not
Sorry, I'm a little late but hope other people will be helped.
You havent changed the SnippetForm class in forms.py to get the bootstrap you'll need to do that in order to get that to work, Just look at the urls.py and you'll understand that the ModelForm and the other Form are in different locations
Very complicated in this modern world
Hey Gabriel,
On my end it's not showing name and email when we use print...
Please share your views file
Do u have code in github?
This is the only tutorial I've seen where they use the FormHelper haha
but why he use helper there ??
Snippet form is not saving. Everything worked fine so far? Can anyone help pls
mine neither, csrf token failing even though i have in the template and syntax is correct
just is i typed my previous comment figured out the in my anchor tag i had placed the enctype attribute to text plain, i did that following a previous tutorial i removed that and it started working.
dasi onnume puriyala da
Pls where is the source
you said that you will provide a link to the python tuts in the video , where is that link ?
Which python tuts? Can you point me to where I said that in the video?
@@thedumbfounds767 Sorry, I guess you said to watch other videos for Django.
@@thedumbfounds767 You mention putting a link to your Python Class tutorial. You say at this @16:50. By the way, I found this tutorial very interesting.
When saving. How do you save a choicefield?? I can not seem to get the choicefield to save to the database..
Can you please help?
Could you post your code on bpaste.net or somewhere else?
The Dumbfounds I will post it tomorrow night. Thank you! I can save everything else to the database except for that choicefield, i just don’t know how to add it to the models.py, I believe that’s the issue
github.com/dinonappa1/CIProject
Here is the code
A choicefield has the user select a value which you want to store on database (I guess). So, you don't have to create a choicefield on the model, just use charfield and set choices=... (whatever choices you have). Take a look at this stackoverflow answer for more information: stackoverflow.com/questions/8077840/choicefield-in-django-model. Does that solve your problem? Btw: seems like you're building a cool project!
Awesome! That did the trick! Thank you!
And thank you! The project is pretty neat! Taking a lot of work. Learning a lot by watching your videos. Keep them coming!
10:14 what is form = ContactForm(request.POST)
When called it will post the data
request.POST will return information body of HTTPresponse. in this case, name and email. and then we use the value to make an object from the ContactForm that he previously created. this way, he didn't need to do manually like "form = ContactForm(name=request.POST["name"], email=request.POST["email"]".
or I could say creating the form right from the request parameter.
Hi bro. Please record video ajax form and vuejs +django. Sorry my English
Hi Ivan, I don't think VueJS will come anytime soon. Thanks for the recommendation!
raise TypeError('HTTP status code must be an integer.')
TypeError: HTTP status code must be an integer. i am facing issue in this line return HttpResponse(request,'form.html',{'form':form}) ..Hw i can reslove this
Coming a bit late, but I think you meant to use the render() shortcut instead of returning the HtthResponse right away (the render function will do that for you).

I HATE even the mention of the word 'context data' i dont know why you need it ..what it means ...when to do it ..its just so impossible to grasp
Context data is just the data you pass to the template used for rendering it. It is just a dictionary with key-value pairs.
thank you , that would make sense.
just play around with it and you'll see how it works :)
