Command to start a project using Django

After executing the above command a project folder will be created with the name project_name

You can have a look at the project directory structure

Command to start an application in a project

python manage.py startapp <app_name>

Open settings.py which is in the sub project folder of the project

For example, as I have created the project named mystore, another sub folder named mystore is created.

In settings.py file add the app ‘app_name’

For example: Here it is ‘garments’

Commands to make migrations

python manage.py makemigrations <app_name>

Ex: here the app is garments

python manage.py migrate

Command to run the server 

python manage.py runserver

Go to http://127.0.0.1:8000

You can find a page like the below.

Open models.py which is in the <application> folder.

For Example here it is garments

Create appropriate fields according to your webpage requirement in models.py

Now you should register the models in admin.py which is in the same <application> folder.

The command to register the application is

admin.site.register(<class_name>)

Create a super user by using the following command

python manage.py createsuperuser

To convert the models to tables use the following command

python manage.py makemigrations <application>

For Example here the application name is garments

so the command is

python manage.py make migrations garments

To create the tables in sqlite batabase use the following command

python manage.py migrate

To run the server use the following command

python manage.py runserver

Click on the url(http://127.0.0.1:8000) and append /admin (http://127.0.0.1:8000/admin)

Use the above created login credentials created using the command createsuperuser

Use can see the admin panel with the name of the application and class created by you previously.

Click on the class name (here it is shirts)

You can add more elements by clicking on add shirt and finally click the save button to save it

Then you can see the object which you have created just now.

Open the database and you can see that the values entered by you in the admin panel are stored in the database.
