Using the Models from two Different Projects in a single script

[Glen D souza]

Hi,

I have two different django projects which each project having different model

Lets say projects to be p1 and p2

Now i have to populate the data from p1 model to a model in p2 ( note p1 and p2 models are different, i just have to use some data from p1 model to move to p2)

Now in order to write the script i have to initialise two different django projects, something like

os.environ.setdefault('DJANGO_SETTINGS_MODULE', "p1.settings")

django.setup()

settings.configure("p2.settings", DEBUG=True)

django.setup()

So i was wondering, is this even possible? and is there any other way

Thanks

Hi Glen,

This won't work – Django uses a whole lot of global state to keep
track of all the settings, model registries, and so on.

I'd suggest an alternative approach, where you'd use a management
command to export the relevant data from one project (either just
dumpdata, or write your own, more specialized version), and then use
another management command in the other project to import the exported
data (again, either write your own custom importer, or use loaddata,
depending on whether you need to transform it in any way).

Good luck,

Michal
