Re: [mezzanine-users] Enable Mezzanine multilingual site support

[Lee H.]

Thanks Mathias,

I think it must have been using the old ordering of INSTALLED_APPS, since 
my settings file came from pre-upgrade Mezzanie. On a clean Mezzanine, I no 
longer got the error.

Re: [mezzanine-users] Adding a third-party app to a multilingual site using modeltranslations

[Lee H.]

Hey Eduardo,

Many thanks for the reply. Yes, you are right, using the django-newsletter 
development branch from github (which has upgrades for the newer django 
migrations without south) things worked, and this error no longer occurred.

Re: [mezzanine-users] Enable Mezzanine multilingual site support

[Mathias Ettinger]

Hi Lee,

To possibilities to fix your problem.

Either you manually added modeltranslation to INSTALLED_APPS in a place 
that is too deep in the loading chain, in this case, just remove it. 
Turning on USE_MODELTRANSLATION will automatically add it to the list.

Or you used the ordering of INSTALLED_APPS provided for Mezzanine 3.1 which 
is not suitable for modeltranslation. Make sure mezzanine.pages is before 
every app that subclass the Page model (gallery, form, shop). Or use the 
list from the development project_template : 
https://github.com/stephenmcd/mezzanine/blob/master/mezzanine/project_template/project_name/settings.py#L206-L226

[mezzanine-users] Re: error on create mezzanine Multi-Lingual Sites?

[Mathias Ettinger]

Hi,

Can you confirm that you’re using the development version of Mezzanine and 
not the version available through pip.

Also what is your version of Django and django-modeltranslation?

Even though it might not be related, you mentionned adding languages to 
settings.LANGUAGES; but do you have a settings.LANGUAGE_CODE defined?

[mezzanine-users] Re: EXTRA_MODEL_FIELDS and django 1.8 migration

[Mathias Ettinger]

Hi Sergey,

Since you’re using the development version of mezzanine, you'd better of 
reading the development version of the documentation.

Have a look at the “Field Injection Caveats” section of 
https://github.com/stephenmcd/mezzanine/blob/master/docs/model-customization.rst

Any feedback will be appreciated, especially if it doesn't seems to work as 
expected.

Mathias

Re: [mezzanine-users] Adding a third-party app to a multilingual site using modeltranslations

[Eduardo Rivas]

Hey Lee.

Their Readme says it's compatible up to Django 1.5. You're using 1.8 or
1.7. Could you verify against a vanilla Django project to see if you get
the same error?

[mezzanine-users] Adding a third-party app to a multilingual site using modeltranslations

[Lee H.]

*Background*

I created a multilingual site theme for mezzanine using the new 
multi-lingual support.
I had to do two things:

1) Add translations.py file to the theme app, which defined translations 
for my custom page models that subclass Mezzanine pages.

2) Split my theme app into two apps: "fronttheme" (with templates/, static/ 
and to go high up in the INSTALLED_APPS), and "backtheme" with the rest, as 
per the note from multi-lingual-sites.rst 

 

*If your app defines both models that need to be translated and static 
content or templates that override default ones from Mezzanine, you'll need 
to split your app to distinguish between presentation and content. This is 
due to conflicting ideas with translated model inheritance, and template or 
static file overriding, in regard to the order of INSTALLED_APPS.*


*The problem*

 All well and good, but now I want to add a third-party add (specifically 
django-newsletter to allow users to sign up to a newsletter. I've used this 
in Mezzanine previously with no issues). If I just install the app, and add 
it to INSTALLED_APPS I get the error

django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.


Does anyone know how I can use a third-party app like this whilst using the 
newer version of Mezzanine with translations?
