Django Model
Django Model
The Django model is a class that is used to store essential fields and methods. Each model has its table in the database. Django uses SQLite as its default database. A database is the collection of data.
Let us understand the whole concept of the Django model with some practical work.
Creating a contact form in the Django model
Open the models.py file of your app and write the code given below.
class Contact(models.Model):
name = models.CharField(max_length=50)
email= models.CharField(max_length=50)
phone = models.CharField(max_length=12)
message= models.TextField()
Here, we have created a class in Django models. Contact is our model name. models.The model means our Contact is a model by, this Django knows that it should be saved in the database.
Name, email, phone, and message are our class attributes and every attribute refers to a different database column. Here, the models, CharField indicates that our class attribute will store a limited number of characters and max_length refers to the maximum length. TextField is used to store text without a limit.

Creating a table for our model in the database
To inform Django that we have made some changes in the database. Use the following command.
\Codersdaily\project1> python manage.py makemigrations
Now, Django has prepared a migration file for us. To apply that in the database use the given command.
\Codersdaily\project1> python manage.py migrate
So, our Django model is now successfully added to the database. But, a new question arises: how can we view the data saved in our Django model? That's where the concept of Django admin comes in.
