Open all files with git merge conflicts in MacVim

git diff --name-only | uniq | xargs mvim

When git encounters a merge conflict, e.g. during a rebase, it drops you back into the shell with a dirty working directory. I like this one-liner for opening all files with a merge conflict in MacVim.

Once you're in Vim, you can then switch between the files with :n and :prev, or another favourite: :w | n (save current file and open the next command line-supplied file).

UPDATE: see below for a version that works with real terminal commands.

	To change a field name in django 1.7+

	1. Edit the field name in the model (but remember the old field name: you need it for step 3!)
	2. Create an empty migration
	$ python manage.py makemigrations --empty myApp
	3. Edit the empty migration (it's in the migrations folder in your app folder, and will be the most recent migration) by adding

	migrations.RenameField('MyModel', 'old_field_name', 'new_field_name'),

	to the operations list.
