The filter mission is to limit the set of records that will be displayed in the list (in any list: related list, open list, the dictionary). The filter is a set of conditions the record must meet to be on the list. Filters can be configured with the condition builder.
For example, we need to filter users live in Sevastopol. In SQL, we use the WHERE clause to filter records.
Filters components
Filters consist of the following components:
- Condition builder (and the breadcrumbs as its integral part);
- Search and sorting:
- Input field at the top of every column is used for searching;
- Click on the column title to sort the search results.
- Filter out/show matching (this item can be found in the context menu, to open it, right-click on the list cell).
All these components form the condition string, which is sent in the request as a GET parameter, and the filtered list of records will be returned and displayed.
Dynamic Filters
Dynamic filters extend the filters by the JS scripts executing ability. This ability is available in the list condition builder and in the dynamic reference qualifier condition builder.
In Condition Builder, dynamic filters are available when selecting the reference field and the 'is dynamic' operator (system name is ISDYNAMIC). After this, the list of available dynamic filters will appear.
When executing the filter as a value of the condition using the 'is dynamic' operator, the value returned by the dynamic filter script will be used.
To create a new dynamic filter, please complete the following steps (a new record in the sys_filter_option_dynamic will be created):
- Navigate to the System Definition → Dynamic Filters;
- Click New, fill in the form and then click Save.
