Hello there i was trying to migrate my database from SQLite to
PostgreSQL following the docs steps but it seems that i encountered a
problem wich i can't resolve.
I think dumpdata and loaddata are for fixtures used in unit tests and
not for migrating between databases.
You need to look at the SQLite docs and the PostgreSQL docs for dumping
and reloading between them.
The nice thing is you can edit the SQL dump file before reloading in the
other database if you need to be clever.

I have a base model called Producto wich has no dependencies.
I have another model called Preaprobado that has the following field:
|
productos = models.ManyToManyField(Producto, related_name =
"preaprobados", default = Producto.objects.get(CMS_id = 1))
|
The thing is that in order for the app to work i need one mandatory
Product with CMS_id field = 1.
I managed to dumpdata from every model separatedly succesfully, then i
changed the DB config in settings.py and was able to run the migrate
command succesfully.
The problem is that when i try to loaddata InitialProducts.json the
console returns an error displaying that the query
|
Producto.objects.get(CMS_id = 1)
|
has no value.
I tried disabling the signals as it says in the loaddata docs
<https://docs.djangoproject.com/es/2.2/ref/django-admin/#loaddata> but
honestly i don't know where should i add the code disabling the
signals since the error is raised when defining the models.py
Any help is more than welcomed.
