Crudit provide some twig helpers.
You can create links to a filtered page with crudit_route_filtered_link
Twig function.
{{ crudit_route_filtered_link('entity', {
'field1': {'value', 'value1'},
'field2': {'value': 'value2', 'op': 'operator2'}
}) }}
The operator is not required, default is "eq". To filter with an entity, just set the id of the resource into the Twig function.
Example :
{{ crudit_route_filtered_link('user', {
'status': {'value': 'generated', 'op': 'neq'},
'active': {'value': '2023-01-01', 'to': '2023-12-31'},
'establishment': {'value': 1}
}) }}
