Currently i filter by some option in django's admin interface. For instance lets say i filter by 'By status'. Is it possible to select multiple statuses to filter results from? Here is the screenshot of the filter:
Can i select multiple items from this list?
Not in the admin UI, but if you modify the URL, you can make the filtering criterion more complex.
For instance, now the URL (after you click on a filter) probably ends with something like
?status__exact=a
You can change this to
status__in=a%2Cm
in order to see both statuses a and m. The %2C encodes a comma.
You can also add the following query to the URL of your list page. in my case if i have multiple option.
?bookingstatus__in=booked,refunded.
You can also add the following query to the URL of your list display page
?my_field__gte=1&myfield__lte=10
for numeric fields. That way you can have a ranged selection. Basically you can use any query you would also use in your code.
