New {% decode %} tag

[Marc Rechté]

Hello,

I would really appreciate a standard "decode" tag that would do a value decoding. Syntax would be:

{% decode var value1 newvalue1 [value2 newvalue2...] [default_value] %}

Examples:
{% decode weather_forecast 'with' 'selected' %}
If weather_forecast equals 'with' return 'selected' else returns

{% decode category '12' '1' '13' '1', '14' '2' '0' %}
If category equals '12', '13' returns '1'
If category equals '14' returns '2'
Any other value returns '0'

Thanks

Thanks for your submission

This kind of logic can be better handled by:

• setting context in your view
• the current if tag
• a custom template tag

as your second example shows - the kwargs-as-a-list syntax gets very hard to follow

also, decode has several other meanings which would lead to ambiguity - but regardless of the name chosen - the functionality doesn't really warrant a new builtin tag.
