Flask Admin extend “with select”-dropdown menu with custom button

问题

Im using the built-in view of flask admin. As you can see in the picture below:

What Im trying is simple: I just want to extend the dropdown menu with a custom button. This button should perfome some action on all selected items. Is there are built-in function of flask where i can simple add an action button?

回答1:

Use the @action decorator. Simple example below, the text "Recalculate Charges" is what appears in the drop-down menu.

class TransactionView(AdminView):

@action('recalculate', 'Recalculate Charges', 'Are you sure you want to recalculate selected transactions(s)?')
def action_recalculate(self, ids):
    count = 0
    for _id in ids:
        transaction_service.recalculate_transaction(_id)
        count += 1
    flash("{0} transaction (s) charges recalculated".format(count))
