Load your own instance by name

If the user is the instance owner, load the instance by name:

# bionty is not in the (schema) modules of mydata
# _check_instance_setup is called inside with from_module=None
# the branch where django is not setup yet
# as from_module=None it won't connect to an instance here
import bionty

ln_setup.connect(
    "mydata", _reload_lamindb=False
)  # also test passing _reload_lamindb explicitly

# wetlab is not in the (schema) modules of mydata
with pytest.raises(ModuleWasntConfigured):
    # _check_instance_setup is called inside with from_module=None
    # the branch where django is setup
    import wetlab

# wetlab is not in the (schema) modules of mydata
with pytest.raises(ModuleWasntConfigured):
    # _check_instance_setup is called inside with from_module="bionty"
    # the branch where django is setup
    # in __getattr__ in __init__.py
