Challenge: Zoo Market Table

4. Working with Database

If you already know how to build a database, then it's time to manipulate data from it. Django ORM is a tool that allows you to work with data from a database. Let's take a look at it, shall we?

Update and Delete Data

Challenge: CRUD with Person

5. Templates

The HTTP response as a string doesn't look good. It is worth correcting this by using DTL technology, which allows you to dynamically generate beautiful HTML pages and return them to the user.

How to create a Model?

Let's write your first model!

Django creates the models.py in your apps automatically. Find the models.py in your created app and work with it.

To write a model, you need to use the models package imported from django.db.

Now, you can create tables in your database. Django is connected to SQLite3 by default.

To create a table, you need to create a model class using the following syntax:

The Model class has needed tools for your models and connecting inherited classes to the database. TableName is the name of the table that you want to create.

The next step is defining the attributes of the table. The id field is created by default, you don't need to implement this attribute.

To implement other attributes (fields), you can define the class attributes and assign different fields to them.

Look at the example:

Here, the CharField, FloatField, and IntegerField are classes that can receive arguments (attributes). These arguments are field parameters that can be defined by Database Management System (DBMS). In our case, DBMS is SQLite3.

Note
The existing fields you can see in the Django documentation.

2. How to create the string attribute (field) in table with the max length 50?
