Scope of the usages

[drozdowsky]

Issue

Let's consider following example (Python 2.7 with django)
models.py

class Example(models.Model):
    date=modelsDateTimeField(...)

other_file.py

from models import Example  
"""some Example usage e.g."""  
post_save.connect(my_function, sender=Example)

Let's say I I run 'show usages' on definition of Example class. (this line: class Example(models.Model)), the jedi-vim/jedi returns only the same line, there is no other_file.py usage shown.
For me it looks like that "show usages" functionality only works when there is direct import and only then jedi can find other usages (it works from other_file.py just fine).
This is a issue because it makes this functionality useless imo, it is more useful to run "grep -r" on whole project.

Output of “:verbose JediDebugInfo”

Unfortunately usages has been bad for quite a long time :( #1059 is IMO still the way to go. I feel like it would solve this.

At the same time I still feel like #1059 is the issue that will eventually solve all your issues.

Sorry!
