Inherit and modify a `Meta` class

django, django-tables2, python

Solution

Try:

class ApplicationTable(ItemTable):
    class Meta:
        model = Application
        fields = ItemTable.Meta.fields + ('jira_bucket_name',)

You'll have the same problems extending `Meta` in a table, as you will in a normal Django model.

Problem

So I have a base ItemTable, and then a number of Tables that inherit from it. I don't seem to be able to modify the Meta class. I tried just including the meta class normally and it didn't work, then I found this bug report and implemented it below. It fails silently: the tables render only with the columns from the parent meta class. ``` class ItemTable(tables.Table): class Meta: model = Item attrs = {"class":"paleblue"} fields = ('name', 'primary_tech', 'primary_biz', 'backup_tech', 'backup_biz') class ApplicationTable(ItemTable): def __init__(self, *args, **kwargs): super(ApplicationTable, self).__init__(*args, **kwargs) class Meta(ItemTable.Meta): model = Application fields += ('jira_bucket_name',) ``` EDIT: Code amended as shown. I now get a NameError that `fields` is not defined.
