Re: How to get Dependent Dropdown Feilds in Django ModelForms. Please answer : Important

[wongX Ndeso]

You can use django form wizard if you want, much easier than you should
manipulate the onclick event using javascript or something similar with
that..
Maybe you should remodel your form or the flow.. Hope this help

Re: problem filtering queryset in Django Rest Framework

[wongX Ndeso]

Try change this,
If self.kwargs[field] is not None:
With
if self.kwargs[field]: <--- this will return True it the field is not empty
This is the better way to filter, if you want filter the fields is empty
then just add not like this example
if not self.kwargs[field]:

Re: django tables 2 - delete column and delete_item for inherited tables

[wongX Ndeso]

Try django generic edit view (CBV).
You can use DeleteView Class to perform what you need to do..

Re: django tables 2 - delete column and delete_item for inherited tables

[wongX Ndeso]

If you use django to perform some delete action, or others like create or
update, please make sure you have csrf_token in your html form file, and
then you should filter if the form is valid or not, then you can process
the data that send from delete page.
