@AbdulAzizBarkat my application name is a store but it shows No installed app with label 'store'. — Dharmendra Kakde, Feb 05 '21 at 10:09
@DharmendraKakde You have not added your app to `INSTALLED_APPS` in the settings — Abdul Aziz Barkat, Feb 05 '21 at 10:10
@AbdulAzizBarkat here is **settings.py** file `INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ]` — Dharmendra Kakde, Feb 05 '21 at 10:16
Yeah. You've to do that. Add `admin.site.register({model-name})` to `admin.py` and then make migrations and migrate. Don't forget to import your model to `admin.py` — Vaibhav, Feb 05 '21 at 10:16
@DharmendraKakde As I said you have not added your app to `INSTALLED_APPS` in the list add an entry `''`. — Abdul Aziz Barkat, Feb 05 '21 at 10:18
@AbdulAzizBarkat Finally, your solution has worked. Thank you so much for your time. — Dharmendra Kakde, Feb 05 '21 at 10:24
@Vaibhav Thank you for your suggestions. I really appreciate it. — Dharmendra Kakde, Feb 05 '21 at 10:25

First you have to create the database with python manage.py migrate. If you have already created your models before doing this step there is no need to do makemigrations. You have to use makemigrations only to collect the new changes and next apply this changes with python manage.py migrate.

Create initialize your DB with python manage.py migrate.
If there are changes collect them with python manage.py makemigrations.
Apply changes to the DB with python manage.py migrate again.

I already initialize DB and admin panel working well. But I need to create another module which is `product`. When I run `python manage.py makemigrations` it shows `No changes detected` – Dharmendra Kakde Feb 05 '21 at 10:13
No need to `initialize` the db before `makemigrations`, would in fact be troublesome if you are using a Custom User model. – Abdul Aziz Barkat Feb 05 '21 at 10:13

Is your app in the INSTALLED_APPS in the settings.py file? – B. Sebastiano Feb 05 '21 at 10:17
@B.Sebastiano As I checked the settings.py file but I didn't get my application name – Dharmendra Kakde Feb 05 '21 at 10:21
I suggest you to check this docs [https://docs.djangoproject.com/en/3.1/intro/tutorial01/](https://docs.djangoproject.com/en/3.1/intro/tutorial01/). Try to check your folder structure. – B. Sebastiano Feb 05 '21 at 10:32
@B.Sebastiano Thank you so much. I appreciate it. – Dharmendra Kakde Feb 05 '21 at 10:36
