Django Xadmin Plugins (2) List view Add a feature column

Take the default Related_link as an example (the last column).

Source: Xadmin.plugins.relate.RelatedMenuPlugin

classRelatemenuplugin (baseadminplugin): Use_related_menu=True# ... A number of limitations    defRelated_link (Self, instance):#... A number of limitations        return '<div class= "dropdown related_menu pull-right" ><a title= "%s" class= "Relate_menu dropdown-toggle" Data-toggle= "dropdown" ><i class= "icon fa fa-list" ></i></a>%s</div>'% (_('related Objects'), ul_html) related_link.short_description='&nbsp;'Related_link.allow_tags=True Related_link.allow_export=False Related_link.is_column=FalsedefGet_list_display (Self, list_display):ifSelf.use_related_menu andLen (Self.get_related_list ()): List_display.append ('Related_link') Self.admin_view.related_link=Self.related_linkreturnList_display

Annotations:

1. Rewrite the Get_list_display method of the Listadminview (control which word Chegacha).

2. The field added here is a field that does not exist for the actual data model, otherwise it is not valid. Detailed look at the Lookup_field method in the Xadmin.util (need to trigger the field does not exist exception, enter the corresponding name of the same-named method call and take its return value), the source code is as follows:

defLookup_field (name, obj, model_admin=None): OPTs=Obj._metaTry: F=Opts.get_field (name)exceptmodels. Fielddoesnotexist:#for Non-field values, the value was either a method, property or        #returned via a callable.        ifcallable (name): attr=Name Value=attr (obj)elif(Model_admin is  notNone andHasattr (model_admin, name) and               notName = ='__str__'  and  notName = ='__unicode__'): attr=getattr (model_admin, name) value=attr (obj)Else: attr=getattr (obj, name)ifcallable (attr): Value=attr ()Else: Value=attr F=NoneElse: attr=None Value=getattr (obj, name)returnF, attr, value

3. The rendering logic for the field needs to be implemented by itself, here is the Related_link method, which ultimately returns the HTML code.

4. Custom field HTML code can parse normally, not be harmonious, don't want to set the Allow_tags property of the method.

Related_link.allow_tags = True

5. The name of the field, through the method of Short_description control.

'   '

6. (To be analyzed) it is amazing that the plugin has no Init_request method, but can control whether the plug-in is loaded through the Use_related_menu property.

The new field returns the HTML code by default, in order to not be harmonious, the method's Allow_tags property needs to be true, as follows

　　

The final effect is to append a column after the list, as follows:
