Hello Dear sir. Today i complete python basic and your DJANGO class. and upload a project in Heroku. I need to internship can you take please internship.
A really good video, covers the basics well - concepts and implementation of basic tables one would need, CRUD and primary/foreign keys. Being a hardcore Oracle DB guy the simplicity of the framework supported models is very refreshing and you've done a wonderful job, at the right pace to explain the essentials. Subscribing to your channel now.
I was having problem understanding models before I saw this video. Now the project I'm pursuing based on models seems like a piece of cake with few hiccups here and there. Thank You so much!!
Your video tutorials are the best Anthony. Can you also demonstrate how to work with many to many relationships through a secondary table where you have other fields too on the relationship?
the first time i tried out this tutorial it was hard ,but now i am able to understand it but i had to first find another models django tutorial from another teacher then compare it to this one. just an advice to beginners dont give up took me one week to get it . i really enjoyed antony's shell than the other instructor
Thank you so much. This is the best django model tutorial that i have ever watched. Can you please make a video about how to create a user login forgot padsword and registration? Once again thanks for this wonderful video. Its simple and easy to understand for the beginners like me.
Really good video, helped me understand the actual representation of the models in the database. I have a question: how would you make it so that the object were created by django itself and not in the shell. Like a button on the website that creates a programming language as the simplest example. Do you have any videos on this topic? Thanks a lot
Great work! thanks a lot. I followed your code and had a break during the video (closed my laptop), but when I came back, it shows that 'django.db.utils.InterfaceError: connection already closed '. Just wondering how to get connection back? is there any command? thanks
Really amazing video I just wanted to ask about connecting the programmer table to the company table, how did django know that I wanted the column ID to from the table company to be the foreign key column in the programmer table, and what if I wanted to have a different column as a foreign key
Great instruction, Anthony! I finally get the whole idea of Models in Django. I'm still not sure why one wouldn't use SQL to insert data as I come from a solid SQL background. I'm yet to understand how does one balance the power of the ORM and the power of the database esp. with functions, cursors, Procs, triggers, etc. Just voicing out as a beginner. Will mature soon. Thanks
Great video! I’m working with a situation where I want to change my intermediary table so that it has a “quantity” column for my project. Could you do a video on working with “through” and “through_field” in Many to Many relationships? I’ve been stuck on it.
I read or try to read books on django. the problem is django structure is a little more confusing as to where to go to find commands and the structure and formate of commands like documentation might show. the thing that I was wondering can you help kind of going through django documentation and books and help us understand the django module commands and structure and the examples in books. the commands to some extent carry over from networking but I think what I need help is how to interpert terms, the examples in the book, and helping us see what they are saying.
Nice video! Congratulations to you for your videos! Please, I have one doubt: in the end of the video (35:26), you added the language python to the programmer Stacy. You didn't save it (stacy.save()) but the query returned both anthony and stacy. Don't you need to save it?
I should have been a little more clear. When adding to a set, you don't need to save because you're not manipulating the programmer directly but another one.
you really cool, super video, I would like to be such an expert like you! Thank you! The most surprising thing is that I do not know much English, but I still understand you.
Hello thank you for the great video. ...I have a django project and it's slightly different from all django project videos I see. ...I have a docs folder right next to the templates folder. ..in the docs folder I have text files. ...when i update or add text document files in the shell console and I follow all your steps to save and migrate and migrations. .it doesn't add the text file to the docs folder and when i look up the words on my browser it only returns the original text files. ..not the text file I added. .....even though if I go back to the python shell console and I can query the new added text file. .it's there.....how can I solve this? ??.....Jessica
After I saw this I have some doubts, What's it's going to be the best approach? MySQL stored procedures or Django framework? What are the best practices, and what is the more secure option?
Thank you again. Just one question. I tried to follow your code. At 30:12 min I've got the following exeption in cmd: ....creatpsycopg2.OperationalError: FATAL: too many connections for role "iorpplro".. and ...django.db.utils.OperationalError: FATAL: too many connections for role "iorpplro"... What does it mean? It's with my pgAdmin4 connection or something else?
how to add style in django template in django.form or any other form in there for django like {{ form.name, class='form-control }} is possible because flask have possible for wtforms if any solution tell me plz... Your video are awesome and very usefull and good explanations thanks for sharing your knowledge
I know this posting is really old but it is a good one. I have a question that I hope anyone can answer here. I am building a mapping tool. It is difficult to create model relationships because the order can be any combination. Ideally, the order is not defined until the user creates it. Which means I have many ManytoMany relationship possibilities. What is the best approach?
Hi I have a question regarding fields. I am trying to make a page for FIFA that has a leaderboard that will display a class 'Player' as well as a list of game history that shows the score of the game, the date of the game played, and connect the users to the game. What kind of field would I specify for the Game class to show what players played the game? Is there a field that I can input that is Player? or would I use user? or can i only connect the class using their name for string?
You never need to remember the primary keys. It's for the database to use. If you want the primary key for something, you just perform a query and then get the key.
@@prettyprinted thanks! I have been trying to connect database on mysql workbench but it is not connecting. I am not sure what I'm doing wrong.. What would you recommend? I also tried using SequelPro but it also doesn't respond like pgAdmin.
Hello, I'm making database project using django and i've got a problem. Database stores information about flights reservations and among others i've got 2 entities - AIRPORTS(id,name) and ROUTES(id,starting_airport,destination_airport). I want either starting and destination airport being id's took from AIRPORTS. Is there any easy way to do it, is my idea even correct?
when I was trying anthony.languages.all() in my cmd, it gave the output as: . I think it is just showing the language id in the example_programmer_language table. I'm not sure where I went wrong . It could be something very small, but could you help me?
Do you know how to alter the table to an already existing database? I want to change the max_length for a field from 100 to 150. I made that change in the models.py and I migrated it and even though the admin is letting me type up to 150 characters I keep getting a database error saying that it will only allow 100. How would you go about that?
Hi , nice presentations, but I got an error during migration, I am beginner level programmer -------- django.db.utils.OperationalError: FATAL: no pg_hba.conf entry for host "myip", user "dell", database "databasename", SSL on FATAL: no pg_hba.conf entry for host "myip", user "dell", database "databasename", SSL off ---------------- can you please help me

Earned a sub from me. Glad there are primers out there that keep it simple but don’t miss the important steps.
Man, 1 minute in and I already love this guy.

thank you for many-to-many relationship's explanation, really helped! You are a cool guy
Thanks man! very clear and precise explanation. Helped me in understanding the many2many relationship between tables.
Thank you for making this! Really clear explanation.
I like that you leave in the simple mistakes that I have made and show how to fix them.
Yeah, no one is perfect. I don't like to give the impression that you can write code without making mistakes.
Good to know what the created tables look like in the database. Thank you.
Thanks for the intro you made my job easier .Thanks

Really amazing video
I just wanted to ask about connecting the programmer table to the company table, how did django know that I wanted the column ID to from the table company to be the foreign key column in the programmer table, and what if I wanted to have a different column as a foreign key
A foreign key should be the primary key to some other table, so Django knows to do that automatically. It doesn't make sense to do it another way.
Thank you. That really helps!
Excellent video!

no such table:example_language?

Add a unique integer field. Have your code update the numbers whenever the student changes the priority.

It would be best to put the players in a separate table if you can help it. Then you'd use a ForeignKey field to connect to it.
This video is really helpful.
One question, when you did reverse query, you used '_set', is there other options too other than '_set' ?
thanks very good explanation, but if the data contain 1000 row, how to remember PK?,
and iam now subscribe your channel !!!
You never need to remember the primary keys. It's for the database to use. If you want the primary key for something, you just perform a query and then get the key.
Nice explanation, does it better to use objects.create() or save() method?
For the most basic case, either one works. Use the one you prefer.
