Integer based MoneyField

It is supposed the aggregation on integer is fast than numeric type in database duo to how they are stored as numeric is represented as string. As money only have 2 decimal place, it can be converted to an Integer despite of its decimal point. The python class decimal.Decimal also has a shortcoming that it is not json serializable(neither cjson nor simplejson). This money field appears as a float number to the front end, so it does not meet the headache as DecimalField. The usage is very simple. In Model: class SomeModel(models.Model): ... income = MoneyField('income') ... Then treat the attribute of the model instance as a normal float type. **Notes** If you try to use aggregation on this field, you have to convert it to float by yourself. Currently I could not find any method to fix this.

ContentType Form

When working with the ContentType model there are generally two issues. 1. Models are listed in the table but not imported. 2. Unicode only returns model not application so being able to select a a app/model is sometimes difficult when to applications have a model with the same name. This snippet gets a listing of imported models and creates a drop down for selection. I also included a function that uses the returned from to get and save the correct ContentType within the primary model.

Conditional Caching

This trick is for caching a view only if it passes some condition, for example, if there are more than zero items in a list. The same methodology could be used for conditional applying of other decorators.

Template filter to convert timecodes into links

This template filter, "jumptime" will find any timecodes in a chunk of text and convert them to links that can be used to jump a video player to that point. E.g., If there is the string "3:05", it will be converted into a link that can be used to jump to that point. This is similar to what youtube does. For information on how to implement, see Django's [custom template tag information](http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#howto-custom-template-tags). You'd use this with some javascript like this: `jQuery(document).ready(function(){ jQuery('a.jumpToTime').bind('click',function(){ player.sendEvent('PLAY'); player.sendEvent('SEEK', jQuery(this).attr('value')); }); });`

Auto-rename duplicate fields

This is useful to run before you add a unique key to a character field that has duplicates in it. It just adds numbers to the end of the contents, so they will be unique. It takes a model class and a field name. The model class can be a South fake orm object, so this can be used inside data migrations.

Printing inline formsets as UL / P

By default all forms created using inlineformset_factory are displayed as tables (because there is only a .as_table method) and there are no .as_p or .as_ul methods in them, so you need to do that by hand.

cache_page that does nothing

When debugging/developing you want to be able to refresh your views every time you make a little change. But when in production mode you might want to cache these views because they contain long and resource hungry calculations or something. By putting this above "hack" in after importing `cache_page` you only cache the views in production mode.
