Re: migrations error

Hi, Camilo, yes of course, i see when create first 0001_initial.py files this file import the models for third party

app, but when uninstall app i apply news migrations i think django migration check all files i discover the import models for the third apps not exit anymore and raise the error, for me maybe this error the migrations a have put example:

initial.py

# -*- coding: utf-8 -*-

# Generated by Django 1.10.2 on 2017-02-09 17:07

from __future__ import unicode_literals

from django.conf import settings

from django.db import migrations, models

import django.db.models.deletion

import hitcount.models     <----- this apps i uninstall

import sorl.thumbnail.fields

import taggit_autosuggest.managers

i create new migrations

0002_auto_numbers

# -*- coding: utf-8 -*-

# Generated by Django 1.10.2 on 2017-03-17 09:46

from __future__ import unicode_literals

from django.db import migrations, models

class Migration(migrations.Migration):

   ....

when i erase this third apps hitcount, in settings. py and uninstall with pip,  I apply the new migrations this error raise:

RuntimeError: Model class hitcount.models.HitCount doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

maybe is a logic bug the django migrations, because if I do not need an app anymore I have to uninstall it!!

Or I'm confused???

cheers

Hi,

Do you have the virtual environment active when you run the migrate command?
