django makemigrations not detecting new model

Question

I used makemigrations earlier in order to make my Django app aware of the tables in my legacy MySql database, and it worked fine. It generated models.py. Now, I want to add a new "UserDetails" model to my app:

class UserDetails(models.Model):
    user = models.CharField(max_length=255)
    telephone = models.CharField(max_length=100)

After saving the file, I ran the following command in the command prompt:

python manage.py makemigrations

But makemigrations is not seeing the new class I wrote inside the models.py, as it always outputs 'No changes detected'

Am I doing it correctly or is there anything wrong with it? I checked my MySQL db and confirmed that no table named UserDetails already exists.

Answer 1

I've met this problem during development and this combination helps me:

python manage.py makemigrations mymodule

This command create migrations for the specific module. It should be in INSTALLED_APPS, but you'll get warning if it's not in there.

python manage.py migrate

Also, mention answer by xiaohen, I've create packages with PyCharm, so I've got init.py file by default.
