问题
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?
回答1:
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.
