//filter/count GET
Overview
Counts filtered records.
Summary
This endpoint will return a count of records filtered by an expression. The filter can be applied to multiple fields and have multiple and/or conditions in it. Alternatively, you may use an existing filter by specifying its id. If both a filter definition and a filter id are passed, the two filters will be joined with an AND
. Care will need to be taken to make sure that any filters used have appropriate indexes on the server side otherwise the runtime of the endpoint will be very long. Related fields can be searched by specifying the field name as: "link_name.remote_field", so if you wished to search the Accounts module by a related member account you would use "members.sic_code".
