Start point of dynmanic models creation.

[Vlasov Vitaly]

Hello.

I have working model factory of dynamic models in my app.models.py. I need to know where i should call it in my code. Right now i call it in MyAppConfig ready() method and think it is not right way. But this is working.
Where i should place dynamic models factory call?

Well problem with Django is that there is not really support for "dynamic models".

Django expects that _before_ calling ready() all models are registered and ready for use.

Also note that ready() maybe called multiple times. You should take into account that for example when running unit tests Django changes database connection, which may affect your model construction.

Yes. I know how django works with dynamic models and this make me sad.

Yes, i know workflow of AppConfigs init. It set models_ready and ready booleans and call AppConfig.ready() then.

I really can't understand why AppConfig.ready() is calling multiple times. This is strange. But this can be fixed by some AppConfig state attribute. (like self.dynamic_models_ready). Anyway my models is unmanaged and can't(i hope) be affected.

May be AppConfig class should have models_ready() method for overwriting. It will be called after setting app models. Actually i can realize this in Django but not sure about neediness...
