LookupError: No installed app with label 'tests'

[Arussil]

Short summary.

Expected behavior

I have a tests folder which contains baker_recipes, conftest, test files etc... #140 this worked:

from model_baker import baker

item = baker.make("tests.item_recipe")

Actual behavior

After installing latest model_bakery i get this error:

LookupError: No installed app with label 'tests'.

As "tests.item_recipe" is interpreted as a django app by _recipe:

def _recipe(name: str) -> Any:
    app_name, recipe_name = name.rsplit(".", 1)
    if "." in app_name:  # probably full path, not app name
        pkg = app_name
    else:
        pkg = apps.get_app_config(app_name).module.__package__
    return import_from_str(".".join((pkg, "baker_recipes", recipe_name)))

Possible solutions:

Moving baker_recipes.py in his own module inside tests does work, but something like:

def _recipe(name: str) -> Any:
    app_name, recipe_name = name.rsplit(".", 1)
    try:
        pkg = apps.get_app_config(app_name).module.__package__
    except LookupError:
        pkg = app_name
    return import_from_str(".".join((pkg, "baker_recipes", recipe_name)))

could probably work, haven't had the time to test it.

Hi @Arussil, is your app named "tests" tests? Because, from the project docs:

You don’t have to place necessarily your baker_recipes.py file inside your app’s root directory. If you have a tests directory within the app, for example, you can add your recipes inside it and still use make_recipe/prepare_recipe by adding the tests module to the string you’ve passed as an argument. For example: baker.make_recipe("shop.tests.customer_joe").

So, probably your call is missing the app name before the tests module in the import string.

Hello @berinhard , maybe i wasn't so clear on my example :D

This is the project folder:

- manage.py
- tests/
  - __init__.py
  - baker_recipes.py
  - conftest.py
  - unit/
  - integration/

"tests" it's not a django app and so it's not in INSTALLED_APPS: this setup worked with model_bakery 1.2.1, before the change to _recipe.

Ow, I see! Thanks the explanation @Arussil! So, this is definitely a bug introduced by 1.2.1.

@Arussil In your example, you call baker.make. Did you mean baker.make_recipe? I don't think the code path executed by baker.make has logic for retrieving recipes and does not call _recipe.
