Mixin for Django Rest Framework View/Viewsets to use different response data/serializers without unnecessary hacks. Just extend your DRFs view/viewset with this mixin after the DRF's APIView (sub)classes.

I have a product table but don't have a brand table. brands in product.brand as denormalized and I want to choose brands from a select tag.
Place the code any admin.py file in your registered apps
See the function docstring.
Add this to your model to be able to get their admin change link from anywhere Useful if you want to jump to the admin screen of an object you are looking at on the front end
A Widget for displaying ManyToMany ids in the "raw_id" interface rather than in a <select multiple> box. Display user-friendly value like the ForeignKeyRawId widget
A couple of useful template filters for splitting a list (or QuerySet) up into rows or columns.
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.
**Success Message has object properties** Success Message can have an object name or the properties of the object model to collide with the message see code below
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).
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`.
This view snippet is a helper for implementing file download handlers. There is a standard to encode Unicode filenames properly, but many browsers have different protocols. The default encoding is assumed to be UTF-8.
How to use =========== Save the snippet to a file utils.py, and add the following view to your Django app: from django.http import HttpResponse from .utils import queryset_to_workbook def download_workbook(request): queryset = User.objects.all() columns = ( 'first_name', 'last_name', 'email', 'is_staff', 'groups') workbook = queryset_to_workbook(queryset, columns) response = HttpResponse(mimetype='application/vnd.ms-excel') response['Content-Disposition'] = 'attachment; filename="export.xls"' workbook.save(response) return response Note: you can use dotted notation (`'foreign_key.foreign_key.field'`) in the columns parameter to access fields that are accessible through the objects returned by the queryset (in that case you probably want to use `select_related` with your queryset).
