Multiple Choice model field
Usually you want to store multiple choices as a manytomany link to another table. Sometimes however it is useful to store them in the model itself. This field implements a model field and an accompanying formfield to store multiple choices as a comma-separated list of values, using the normal CHOICES attribute. You'll need to set maxlength long enough to cope with the maximum number of choices, plus a comma for each. The normal get_FOO_display() method returns a comma-delimited string of the expanded values of the selected choices. The formfield takes an optional max_choices parameter to validate a maximum number of choices.

Overwrite File Storage System
This is a simple implementation overwrite of the FileSystemStorage. It removes the addition of an '_' to the filename if the file already exists in the storage system. I needed a model in the admin area to act exactly like a file system (overwriting the file if it already exists).

Hand over model instance relations to another instance of the same model
If you have a model instance you want to merge into another, it's handy to hand over all the relations into the model you want to merge into, so the deletion won't trigger cascading deletions from other tables. You can pass an `Iterable` of the same objects (a.k.a `QuerySet`) to the model, and then process it with the new model's `pk`.
