Requires [PyISBN](http://pypi.python.org/pypi/pyisbn/0.5.2). Use like so: class Book(models.Model): title = models.TextField() isbn = ISBNField() ... the link in the widget can be changed to amazon, borders, you name it. If the DB version is a 13-digit ISBN, the display box contains the 10-digit, labeled; and vice-versa.
**What It Is** This is a JavaScript-based solution to dynamically add and remove forms in formsets and inlineformsets. It requires jQuery. Originally based on this Snippet: https://djangosnippets.org/snippets/1389/ I have done a lot of work to make it OO, and am using it in production on pages with multiple inlineformsets, and even nested inlineformsets (I call it, "Inlineformset Inception"). My hope is that the code and example are enough to show how it works. **Usage Details** In the example usage, I am using a CSS class, 'light', to make every other form have a light background color. My form placeholder is an element with an ID of 'formset-placeholder' (the default). And the form selector is a class name of 'dynamic-form' (the default). When I have time, I will create a GitHub repository with the code and completed examples.
Simple filter for django ModelAdmin How use: #models.py class ObjectWithGenericForeignKey(model.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object= GenericForeignKey('content_type', 'object_id', for_concrete_model=False) #admin.py class CommentAdmin(admin.ModelAdmin): list_filter = (get_generic_foreign_key_filter(u'Filter title'),)
Some times if third party application is not translated competelly, developer have to extract and save all of **i18n** strings of third party application to current project, somewhere in root project directory (and configure additional `LOCALE_DIRS` entry) or in any project's applications (usually named "main" or same as project). And after, create **po** file by makemessages, completely translate it and compile it to **mo** file. This script allows you to extract all messages (`msgid`) from all **po** files and save it in **python** file in **django** format — `_("Some i18n message")`, and also compile complex **po** file, contained all **msgids** with related **msgstrs** of third party application. Full example: You have third party app, which is translated to russian, but not completely and names **blog**. It contains two locale dirs and have, for example, the following structure: blog ..locale ....ru ......LC_MESSAGES ........django.mo ........django.po ..contrib ....comments ......locale ........ru ..........LC_MESSAGES ............django.mo ............django.po ......__init__.py ......models.py ..__init__.py ..models.py ..urls.py ..views.py Each po file may contains any set of strings, which may be duplicated accross the application and any other po files, anyway result **po** file will be contain only unique **msgids** and **msgstrs**. This application installed by pip into virtualenv lib directory and of cource you do not want change code here. To translate this application in your project it is possible to copy all (unstanslated) strings to you project as `ugettext` entries (usually `_("Some i18n string")`), make **po** file, translate it and compile **mo** file. So, after call this script (for example, let it be named `pomessages.py`), you will get two files, **django.py** which contains all i18n strings and **django.po** which contains all **msgids** (i18n strings) with related translations. `pomessages.py path/to/third-party-app/root locale [project-name:default is empty] [filename:default=django]` In this case: `pomessages.py path/to/blog ru blog django` After script will be finished, in blog directory will be added two files, **django.po** and **django.mo**. **django.py** content: ... # blog:admin (source:ru) directory translations # ---------------------------------------------- _("Category") # blog:models.py:10, blog:views.py:15 _("Article") # blog:models.py:20 # blog:category/admin (source:ru) directory translations # ------------------------------------------------------- _("Add Category") # blog:category/admin/templates/admin/create.html:10 _("Edit Category") # blog:category/admin/templates/admin/change.html:20 ... **django.mo** content: ... # msgid "" msgstr "" "Project-Id-Version: Blog\n" "POT-Creation-Date: 2016-02-08 12:00+0000\n" "PO-Revision-Date: 2016-02-08 18:00+0000\n" #: path/to/file.py:10 msgid "Category" msgstr "Категория" #: path/to/file.py:20 msgid "Article" msgstr "" ... After you just need to place **py** file anywhere in your project and place **po** file to the following locale directory (or merge with existing **po** file if it exists), run: `django-admin makemessages -lru` to fix **po file** (remake it), translate missing entries and run: `django-admin compilemessages`, reload project and you will have translated third party application.

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.
This very simple templatetag can take event objects from django-event-calendar and create the appropriate URLs to automatically allow users to add events from your website to Google calendar.
This closure lets you quickly produce date-style range filters in the Django Admin interface without having to create a new class for each one. It follows Python range semantics, with the lower value using a `_gte` test and the upper value using an `_lt` test. Here's an example of how I'm using it in one of my projects: list_filter = ('complete', ('chapters', makeRangeFieldListFilter([ (_('1'), 1, 2), (_('2 to 10'), 2, 10), (_('11 to 30'), 11, 30), (_('31 to 100'), 31, 100), (_('At least 100'), 100, None), ], nullable=True)), ('word_count', makeRangeFieldListFilter([ (_('Less than 1000'), None, 1000), (_('1K to 5K'), 1000, 5000), (_('5K to 10K'), 5000, 10000), (_('10K to 75K'), 10000, 75000), (_('75K to 150K'), 75000, 150000), (_('150K to 300K'), 150000, 300000), (_('At least 300K'), 300000, None), ], nullable=True)), ('derivatives_count', makeRangeFieldListFilter([ (_('None'), 0, 1), (_('1 to 5'), 1, 5), (_('5 to 50'), 5, 50), (_('50 to 1000'), 50, 1000), (_('At least 1000'), 1000, None), ])), 'pub_date', 'upd_date') It is based on code from `DateFieldListFilter` and `BooleanFieldListFilter` from `django.contrib.admin.filters`.
Generic function to merge model instances. Useful when you need to merge duplicate models together, e.g. for users. Based on http://djangosnippets.org/snippets/382/, with several enhancements: * *Type checking*: only Model subclasses can be used and testing that all instances are of same model class * *Handles symmetrical many-to-may*: original snippet failed in that case * *Filling up blank attrs of original when duplicate has it filled* * *Prepared to use outside of command-line*
PreviewMixin adds a preview page for Django's CBV (FormView, UpdateView, CreateView). After a form has been submitted, it is returned again, optionally in a different template to confirm. If the form is submitted with the same data, the default "form_valid" function is executed. Features: 1. `process_preview` - function executed after submitting the form for the first time (default is to do nothing) 2. `done` - function for the action if the confirm page is sent (defaults to whatever form_valid of the django cbv does) 3. `preview_template_name` - variable with the name of the template for the confirm page (defaults to taking the same template as for the initial form) 4. new function `security_hash` to calculate a hash which is added to the confirmation form. Works kind of like django-formtools, just as a Mixin for the default Django cbv.

**CancelMixin** A simple mixin to use with ```generic.CreateView``` and ```generic.UpdateView``` view form templates to effortlessly implement a "Cancel" button. This smart mixin will add a URL to your context, ```{{ cancel_url }}```, that can be used as a cancel link in your form template. If no referrer URL is provided, the cancel button will link to ```default_cancel_url```, which can be overridden by view. ** **
