This function emulates the file upload behaviour of django's admin, but can be used in any view. It takes a list of POST keys that represent uploaded files, and saves the files into a date-formatted directory in the same manner as a `FileField`'s `upload_to` argument.
An example for using bootstrap theme for django-endless-pagination or django-el-pagination as asked on [http://stackoverflow.com/questions/30149152/how-to-set-bootstrap-theme-for-django-endless-pagination](http://stackoverflow.com/questions/30149152/how-to-set-bootstrap-theme-for-django-endless-pagination) I used django-el-pagination to make it work on Django 1.9 and Bootstrap v4.0.0-alpha2, but same method should work on django-endless-pagination. For Bootstrap 3, you may consider removing extraneous classes in <li> and <a>.

This is an updated version of http://www.djangosnippets.org/snippets/628/ now working with Django's new Paginator class, instead of the deprecated ObjectPaginator. See: http://blog.elsdoerfer.name/2008/05/26/diggpaginator-update/
You can see full examples on the page [GitHub](https://github.com/abbasovalex/django-SplitJSONWidget-form)
**Use Case**: Specify the DB to run tests against. For example, use a legacy DB (un-managed), or a read-only DB where it is un-important to test creation, but important to test connection, trigger functions, and that models match schema. **Usage**: in DATABASES setting, add: 'TEST' :{ 'USEDB': 'your_test_DB_name_here', } and setting: `TEST_RUNNER = 'your_app.test_runner.UseDBTestRunner' ` Advantages over --keepdb: 1. DB specific setting for multi-DB setup (e.g., default can use normal test DB, while legacy can use a pre-existing table). 2. Can specify any DB table, including the one used by the app (for non-destructive tests, or dev DB) 3. Allows testing against DB where creation or copying is prohibitive.
You can use this as a model method.
django-substitution-user is a project that makes it possible to substitute user, if you logged in as superuser https://github.com/torchingloom/django-substitution-user
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.
Create a list of pages using Django 1.8 and marks the current page. Using Bootstrap. * "list_itens" is a list of itens paginated.
This is a username field that matches (and slightly tightens) the constraints on usernames in Django's `User` model. Most people use RegexField, which is totally fine -- but it can't provide the fine-grained and user friendly messages that come from this field.
### Usage: class Foo(models.Model): description = models.TextField() number = models.IntegerField() class FooOnlyDescriptionIsReadOnly(ReadOnlyFieldsMixin, forms.ModelForm): readonly_fields = ('description', ) class Meta: model = Foo fields = '__all__' class FooAllFieldsIsReadOnly(ReadOnlyFieldsMixin, forms.ModelForm): class Meta: model = Foo fields = '__all__' ### or use the function class FooForm(forms.ModelForm): class Meta: model = Foo fields = '__all__' ReadOnlyFooForm = new_readonly_form_class(FooForm, readonly_fields=('description', ))
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'
I've reimplemented the code I found somewhere on the web within my models file. The earlier version was incapable of converting all formats to JPG while this code converts all formats and compresses all of them successfully. You need to have PILLOW installed for this to work.
Using this snippet you can easily create Pagination that preserves any additional GET paremters you may be using (for example for search module)
