PyCharm - some breakpoints not working in a Django project
Just like other folders on the left side of your project, there will be a '.idea' folder on the top must be there. Delete that '.idea folder'. Close the project. Open it again. It solved my issues.
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?
