Repository: django-wiki/django-wiki

Issue:
Initial installation fails with 'django.db.utils.ProgrammingError: relation "notify_subscription" does not exist'
The error is that the migrations for 'wiki' do not depend on the 'django_notify' app.

In particular, you get this error on wiki:0007_auto__add_articlesubscription. It just needs to add:

```
depends_on = [("django_notify", "0004")]
```



Discussion:
Thanks! I think I see a general, more odd/wrong behaviour here. All of the plugins have `Meta.app_label` set because that creates a nicer db layout and also because the apps have very generic names. For instance as introduced in this commit:

https://github.com/benjaoming/django-wiki/commit/8a7a3e758cf7c09e5516f62ae75994fdbdd750ab

However, apparently setting app_label to "wiki" has caused South to put plugin migrations in `wiki/migrations` which is not really the intention. Because then the tables will be created even if the plugins are not installed + as you report, then it spawns a dependency on django_notify.

I guess I need a remedy to make South put the migrations with their respectiv apps.. but I'm wondering if this means getting rid of the app_label. And in that case, renaming tables would be terribly incompatible with running deployments :)

Seeing the response to this bug report makes me worry that using app_label is completely wrong:

http://south.aeracode.org/ticket/1128

It could well be that all the plugin models should start specifying `Meta.db_table` in order to have wiki_ prefixes.

https://docs.djangoproject.com/en/dev/ref/models/options/#db-table

I found out that if I set the INSTALLED_APPS in the right order, I don't have this problem. But the correct solution is still to use 'depends_on' in the migration.

I think as long as the wiki plugins are within the wiki codebase, there is no problem using 'app_label'. That ticket was about someone using an 'app_label' for models within a completely separate library.

I'm going to fix this by completely breaking stuff instead.

The old package django_notify supplied in `wiki` was supposed to be standalone, but a name clash ruined that. Instead, I've renamed everything and put it here:

https://github.com/benjaoming/django-nyt

Docs are there from day 1 :)

Now we just need to refactor some stuff in django-wiki and put django-nyt on pypi.

Hello -
I still seem to be having an issue with the `wiki:0007_auto__add_articlesubscription` migration regardless of the order...  The `django_notify` library installed from `pip` does not even have any models...  I'm sure I'm missing something obvious here, but any help is appreciated.

Perhaps I need to update that migration to look for `nyt_subscription` instead of `notify_subscription`?

---

UPDATE:
Sorry for posting just prior to resolving my issue.  But, my guess in question form above was indeed correct.  I updated the `wiki:0007_auto__add_articlesubscription` migration file to replace all `django_notify` instances with `django_nyt` and all `notify_` instances to `nyt`,

@dannybrowne86 thanks for pointing this out, we should indeed update the migrations for the 0.0.24 release.
