问题:

I know how to run commands with PyCharm (Tools -> Run manage.py Task), but I would like to debug them also, including my commands and third party app's commands.

回答1:

You can debug a custom Django admin/management command in PyCharm by creating a custom Django server entry on the Run/Debug Configuration menu:

Click Edit Configurations....
Click the plus sign and choose Django server.
Fill in the Name as you please, clear the Host and Port fields, check Custom run command and enter the name of your command to the right of the checkbox.
Enter any extra command-line arguments into the separate field Additional options, not appended in the run command.
Click OK.

Now set a breakpoint, choose your new configuration from the Run/Debug Configuration menu and click the Debug button. Et voilà!

Since clearing Host and Port will not make the command run at all (PyCharm 5), the solution I found is to use a Python run configuration instead of a Django server. Fill Script with your manage.py script, other parameters in Script Parameters, and adjust your environment such as Working directory.
