Readonly fields with link to change page in admin
Usage : class MyModelAdmin(ReadonlyLinksMixin, admin.ModelAdmin): readonly_fields_links = ('field1', 'field2') This adds a new ModelAdmin property (`readonly_fields_links`) that acts like the default `readonly_links` except that (if the field's type is a model that can be edited in the admin site) the value of the field has a link to the object. Same functionality as * [This snippet](https://www.djangosnippets.org/snippets/937/) * [and this one](https://www.djangosnippets.org/snippets/1008/) Except that it works without messing with the form that gets validated and saved, and thus without sometimes saving None values. It uses the documented property that `readonly_fields` can be callables ([Django doc](https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display)) : the fields in `readonly_links_fields` are turned into callables that are appended to `readonly_links`. Each callable creates the linked value.

Reusable form template with generic view
If you require lots of forms in your project and do not want to be creating an extended template for each one I propose this solution. Classes in the html correspond to bootstrap, you can work without them if you do not use bootstrap.

Middleware for fixing Microsoft Office (Word, Excel, Powerpoint) hyperlinks to views requiring authentication
Hyperlinks to views requiring authentication in Microsoft Office (Word, Excel, Powerpoint) can fail based on how Office handles rendering. This middleware sends a refresh return to the client, which will allow the page to be opened as normal, instead of the "Unable to open ... Cannot download the information you requested." This is a port from the ruby middleware project [fix microsoft links](https://github.com/spilliton/fix_microsoft_links). To enable, add to your [middleware stack](https://docs.djangoproject.com/en/dev/topics/http/middleware/) in the django project settings.

Django EncryptedField
Inspired by [Base64Field: base64 encoding field for storing binary data in Django TextFields](https://djangosnippets.org/snippets/1669/) but in a generic way. from django.db import models import base64 class Base64Encryptor(object): def encrypt(self, value): return base64.encodestring(value) def decrypt(self, msg): return base64.decodestring(msg) class MyModel(models.Model): ... b64_data = EncryptedField(encryptor=Base64Encryptor) ... # Usage my_obj = MyModel() my_obj.b64_data = "hello" print(my_obj.b64_data) # will output 'hello' print(my_obj.b64_data_enc) # will output 'aGVsbG8=\n'

Ellipsis paginator decorator with first and last two items
Use this template tag to get a paginator showing the first and last two pages w/ adjacent pages using ellipsis. The `page` parameter is a page of a `Paginator` (typically the first but you can use whichever you want). In case of 50 pages, while being on the 40th, it'll give you the following iterable of `int`s (with `settings.PAGINATOR_ADJACENT_PAGES = 2`): `(1, 2, 38, 39, 40, 41, 42, 49, 50) ` You get the idea.

Make HTML5 appcache manifest slice work with django-compress compressed files
I needed to make appcache for my application which used django-compress for JS and CSS compression. This is, how I solved the problem with putting compressed files into the manifest. I went for offline compression (with `COMPRESS_OFFLINE=True`). This snippet shows code of command file (put it in `apps/cyklomapa/management/commands/compress_create_manifest.py`), which creates `compress_cache_manifest.txt` file in my templates. Then I just use `{% include "compress_cache_manifest.txt" %}` in my appcache template.

Mutiple forms on Form wizard
Wraps many Form subclases in order to get a form wizard to treat them as one. Many Forms will use one step. **Example:** `class LanguageVerifiedHumanForm(MultipleForms): base_forms = [ ('language_form', LanguageForm), ('verified_human_form', VerifiedHumanForm) ]` `class NewGuideWizard(SessionWizardView): form_list = [ ('guide_form', GuideForm), ('multi_form', LanguageVerifiedHumanForm), ]`

Dynamic formset without javascript
If using javascript is not an option, you can use something like this code to have a variable number of subforms. This code uses crispy-forms, but it is totally dispensable.

Django filter for shrinking [big] numbers
Simple filter that shrinks [big] numbers sufixing "M" for numbers bigger than million, or "K" for numbers bigger than thousand. It does a division over the number before converting to string so rounding is properly done. Examples: `{{ 123456|shrink_num }} >> 123.6K` `{{ 1234567|shrink_num }} >> 1.2M`

Remove a clause from a queryset
I want to create Mixins for QuerySet objects that will by default filter out certain records (e.g. filter out "deleted" records, or filter out "unapproved" records, etc). I'd like those to be separate independent mixins. So in each of those, I override all() to filter out deleted or unapproved, etc. But, I also want to offer a method in the queryset to remove those filters or remove some part of those filters. That's where this code comes in. After some examination of how QuerySets work, this seemed like the simplest method for "undoing" some filter in a queryset
