Comment (by rvernica):

 I was able to move past this by adding the following to the `dependencies`
 field in the `Migration`:
 {{{
 class Migration(migrations.Migration):

   dependencies = [
 ('NAME_OF_RELATED_APP', 'LAST_MIGRATION_IN_THAT_APP'),
 ...
   ]
 }}}
 Now `sqlmigrate` works as expected.

 After looking around it seems that this problem has been encountered
 before and this solution worked in the past.

Comment (by debugger22):

 I think this bug is still there in Django 1.9.3. Yesterday, I just added
 `null=True, blank=True` to a `ForeignKey` field and executed `python
 manage.py migrate` after `makemigrations` and it refused to migrate
 stating the same error.

Comment (by loic84):

 @charettes, interestingly, it's not the same error, but rather
 `ValueError: Lookup failed for model referenced by field
 auth.Permission.content_type: contenttypes.ContentType`.

 I find that generating migrations for `d.c.contenttypes` then `d.c.auth`
 fixes the problem up to the point of #22485.

Comment (by loic84):

 @maxwell.team did you try to remove the faulty migration after applying
 the patch, then running `makemigrations` and finally running `migrate`
 again?

 Also you may want to try the master version of django on github, since
 this patch has been merged already.

 Feel free to ping me on the #django-dev IRC channel (loic84).

 I've same problem with my

 {{{
 content_type = models.ForeignKey(ContentType)
 }}}

 changing to

 {{{
 content_type = models.ForeignKey(ContentType, null=True, blank=True)
 }}}

 I've tried to apply patch – but the error remains:

 {{{

Comment (by dbinetti@…):

 so sorry for the late response!  i assumed i'd be notified of followups.

 as it turns out I changed my model schema, and have not experienced this
 since.  so perhaps it worked, perhaps some other solution, but in any case
 no problems since.

 thanks!

 @dbinetti, did you delete the existing migrations? This patch fixes the
 generation of migrations, but if your migration is already generated, it's
 not going to help.

Comment (by prairiedogg):

 This is also happening to me in a simple and reproducible case where I add
 a foreign key on a model to ContentType, `makemigrations` generates the
 migration just fine, but `migrate`raises the same `ValueError: Related
 model 'contenttypes.ContentType' cannot be resolved` error.

Comment (by melinath):

 This seems to be resolved (in the case where I'm getting it now - a rel to
 auth.Group) by adding a dependency to `auth.__first__` - not sure why that
 wasn't automatically added. Also not sure why I was seeing this before,
 since swappable_dependency *was* present and seems to just be a shortcut
 to `app_label.__first__`

Comment (by melinath):

 81f5408 is the first commit where the migrations that are autogenerated
 start exhibiting this behavior - but they have this behavior all the way
 back to 1.7a1, at the very least, once they've been generated. (I get
 different errors for my migrations that are generated *before* 81f5408, so
 I can't tell whether the generation is also wrong before that.)

 This *particular* bug starts showing up in
 
https://github.com/django/django/commit/81f5408c7a16b8c79053950f05fe7a873506ca55
 (git bisect) but I don't know whether that commit causes it or just
 uncovers it.

Comment (by melinath):

 I'm seeing this as well. Just tried to re-generate my migrations, and they
 won't run. I got it with auth.User, whether I specify it as 'auth.User' or
 by importing the model. It looks like the migration doesn't run
 do_pending_lookups for models from external apps, for some reason.

 Hey!

 It only happens for this model so when I remove Link fk everything passes
 smoothly
