PyCharm - some breakpoints not working in a Django project
While I don't know why or how, the problem was resolved by deleting the ".idea" directory within the Django project directory. This is where the PyCharm project data lives, so by removing this directory you will lose your project specific settings, so just be aware. Hope this helps someone else.
I'm seeing some bizarre behaviour in PyCharm. I have a Django project where breakpoints stopped working in some files but not others. For example, all the breakpoints in my app's views.py work fine, but all the breakpoints in that same app's models.py are just ignored. 
I've tried the following but no joy:

double-check the breakpoints are enabled
removing/re-adding the breakpoints
closed/re-opened the project
quit & re-launch PyCharm
delete my configuration and create a new one

Some details:

PyCharm 2.7.3
Python 2.7.2 (within virtualenv)
Django 1.5.1

I'm not using any special settings in my configuration. Any ideas?
