Comment:
Hi again:
Sorry, it's been a while. I cannot share my code due to confidentiality,
but I think I found a solution.
I was debugging migrate command to see what changes are being detected.
Then, I have called write_migration_files(changes) from makemigrations
command using the changes detected before. After this, I have new
migrations created for the mentioned apps. Most of the changes are only
verbose_name related (Spanish translations) and minor updates, so I think
it should be safe to migrate.
The question is: why did migrate command detect these changes (see below)
but makemigrations did not? I think both changes autodetector should work
the same way to avoid problems like this one.
These are the changes detected by migrate command (but not by
makemigrations) related to Django default apps:
admin app:
