Forcing DB on relationship manager with multiple database project

I have a master/slave SQL setup and sometimes I need to access the data immediately after write, but the data has not yet propagated to the slave yet. This forces me to require `.using('default')` every time that relationship is accessed. Ex: self.books.using('default').all().delete() Setting `objects = ForceDefaultDBManager()` on the related object removes this requirement throughout your code. This now does the same as the last example: self.books.all().delete()

Extended Seconds-to-Duration Template Tag

Extended Template Tag initially created by Dan Ward (http://d-w.me): https://djangosnippets.org/snippets/1398/ The default setting has been renamed to normal, output stays the same. If you have used the old tag with ':short' you have to remove or rename it to ':normal' for the same ouput! As an example, given the duration 84658: Short: 23:30:58 Normal (default): 23 hrs 30 mins 58 secs Long: 23 hours, 30 minutes and 58 seconds Best regards, Gregor Volkmann

Another Multiform

MultiForm and MultiModelForm Based on a PrefixDict class I wrote and thus very lean. Lacks a little documentation, though class MyMultiForm(ModelMultiForm): class Meta: localized_fields = '__all__' form_classes = OrderedDict(( ('form1', Form1), ('form2', Form2), )) Subfields are named `form-name` `prefix_sep` `subfield-name`. `prefix_sep` defaults to `-`. For access in templates, use `form.varfields`, which uses `var_prefix_sep` (default: `_`), instead. multiform.varfields()['form1_field1']

Loading initial data per model at table creation (useful with migrations)

A very simple way of automatically loading data on model creation. As I am using South I wanted an automatic way of loading initial data only when a new model is create during a migration. Django provides almost everything out of the box by providing the *post_syncdb* signal (triggered also by South migrate command) and the *loaddata* command. The code will simply look for a an existing fixture named `<model>_initial.*` and invoke the *loaddata* command to try to load it Note: beware *post_syncdb* signal is deprecated since version 1.7: it has been replaced by *post_migrate*.

MultiRangeField and MultiRangeFormField

**Designed to hold a list of pages and page ranges for a book/magazine index.** A custom model field (and accompanying form field) that saves comma-separated pages and page ranges in human-readable string form. Includes some clean-up code, so that you can add a new page or range at the end of an existing entry, and it will put it in numeric order and combine runs into ranges. So this: 4-33, 43, 45, 60-65, 44, 59 becomes the tidy 4-33, 43-45, 59-65 **NOTE:** If you comment out the raising of the `ValidationError` in the form field's validate() method, it will actually clean up any extraneous characters for you (which could be dangerous, but for me is usually what I want), so even this horrible mess: ;4-33, 46a fads i44 ,p45o gets cleaned to 4-33, 44-46 *This is the first custom field I've ever written for Django, so may be a little rough but seems to work fine.

Pretty Print Template Tag

This defines a new template tag that lets you print your rendered templates (or partial templates) in html that has been prettified by beautiful soup. It is dependent on the beautiful soup library (bs4). Not recommended for production but it is helpful for development and serving readable html. {% load whatever_template_file %}' <body> {% pretty %} <h1>Hello, world.</h1> {% endpretty %} </body>
