    44
    5 This ticket adds:
     5Ticket goals are:
    66
    7  * beautifully API to admin change list customization
     7 * to change list_display syntax;
     8 * add to list_display_links the same items type support as list_display has (Now Django allows to use in list_display_links only model fields, properties or methods).
    89
    9  * ability to customize and localize 3rd-party application without fork it
     10The current approach for customising list_display seems contrary to the spirit of newforms-admin. Method properties such as .short_description, .boolean and .allow_tags rarely belong in the model definition.
    1011
    11  * ability to apply custom template filters on field value or model method returned value without any magic
    12 
    13  * ability to specify witch field will be used in order for column based on model method
     12In fact, I noted that these options, for customising the look of the list column, duplicate filter functionality. .allow_tags is exactly |safe; |boolean could be a filter provided by django.contrib.admin.templatetags. The case is much more convincing when you take into account user-defined filters: if I already have a filter for presenting values for user consumption, I should not need to provide a model method to replicate or apply that filter.

     92In the example
     93
     94{{{
     95admin.ListColumn('baz', filter='truncatewords:"2"|slugify'),
     96}}}
     97
     98would render exactly the same as
     99
     100{{{
     101{{row.baz|truncatewords:"2"|slugify}}
     102}}}
