Apply migrations and models from all the apps in Django

I'm using Django and I have an schema like this:

mainapp
|---mainapp
|   |---migrations.py
|   |---models/
|---app2
    |---migrations/
    |---models/

But, when I execute:

python manage.py migrate it is generationg the tables of mainapp/models, but no the app2/models and app2/migrations either.

How can execute those migrations?

First to INSTALLED_APPS in settings.py, you need to set all apps which you want to make migrations and migrate for as shown below:

# "settings.py"

INSTALLED_APPS = [
    'app1',
    'app2'
]

Then, run the command below which can make migrations for all apps set in INSTALLED_APPS in settings.py:

python manage.py makemigrations

Then, run the command below which can migrate for all apps set in INSTALLED_APPS in settings.py:

python manage.py migrate

In addition, you can make migrations for specific multiple apps by specifying them as shown below:

python manage.py makemigrations app1 app2

But, if you specify the apps which are not set in INSTALLED_APPS in settings.py as shown below:

python manage.py makemigrations app1 app2 app3 app4

Then, there are the errors below so no migrations are made for all the specified apps:

No installed app with label 'app4'.
No installed app with label 'app3'.

In addition, you can migrate for only one specific app by specifying it as shown below:

python manage.py migrate app1

But, you cannot migrate for multiple specific apps by specifying them as shown below:

python manage.py migrate app1 app2

Then, there is the error below:

CommandError: Cannot find a migration matching 'app2' from app 'app1'.

Make sure you have added the app in the installed apps.

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'mainapp',
    'app2',
    #......,
    #......,
]

Then create migrations

using python mananage.py makemigrations and migrate with python manange.py migrate

first of all try

python manage.py makemigrations

for a specific app

python manage.py makemigrations appname

this will migrate all the apps

then 

python manage.py migrate

hope it helps
