Apps with lable XYZ could not be found

Question

Hello folks,

today I ran into an error and have no clue how to fix it.

Error: App with label XYZ could not be found. Are you sure your INSTALLED_APPS setting is correct?

Where XYZ stands for the app-name that I am trying to reset. This error shows up every time I try to reset it (manage.py reset XYZ). Show all the sql code works.

Even manage.py validate shows no error.

I already commented out every single line of code in the models.py that I touched the last three monts. (function by function, model by model) And even if there are no models left I get this error.

Here http://code.djangoproject.com/ticket/10706 I found a bugreport about this error. I also applied one the patches to allocate the error, it raises an exception so you have a trace back, but even there is no sign in what of my files the error occurred.

I don't want to paste my code right now, because it is nearly 1000 lines of code in the file I edited the most.

If someone of you had the same error please tell me were I can look for the problem. In that case I can post the important part of the source. Otherwise it would be too much at once.

Thank you for helping!!!

You don't specify which server you're using. With Apache you'll almost certainly need a restart for things to take effect. If you're using the development one try restarting that. If this doesn't work you may need to give us some more details.

I'd also check your paths as you may have edited one file but you may be using a different one.

Plus check what's still in your database, as some of your previous versions may be interfering.

Finally as a last resort I'd try a clean install (on another django instance) and see if that goes cleanly, if it does then I'd know that I'd got a conflict, if not then the problem's in the code.
