_filterhack(qs, s, args)

DataTables 1.10.12 has built-in support for filtering based on a value in a specific column; when this is done, the filter value is set in columns[N][search][value] where N is the column number. However, the python datatables package used here only supports the global search[value] input, not the per-column one.

However, the DataTable search is implemented by passing a callable to table.searchable() which takes two arguments, the current Query that’s being built, and the user’s search[value] input; this must then return a Query object with the search applied.

In python datatables 0.4.9, this code path is triggered on if callable(self.search_func) and search.get("value", None):

As such, we can “trick” the table to use per-column searching (currently only if global searching is not being used) by examining the per-column search values in the request, and setting the search function to one (this method) that uses those values instead of the global search[value].

Parameters:

• qs (sqlalchemy.orm.query.Query) – Query currently being built
• s (str) – user search value
• args (dict) – args

Returns:

Query with searching applied

Return type:

sqlalchemy.orm.query.Query
