Query Based Permissions
A new method for selecting permissions for apps has been added. Selecting via query allows you permission data based on their values. For example, you can select all orgs of type "school" or all classes containing "English" in the title. To add via query, click the dropdown menu in the top left and then click "Select via Query".
In the menu that appears, click the "+" icon to add a query. From here, you can select what field to select by, what relation to select by, and the value(s) to search for by clicking their respective column. In the screen below, all orgs with the type of "school" will be selected.
When making a query for Orgs or Courses, you can preview the results of your query by clicking the "Preview Query Result" button in the top right. Please note that this option is only available when selecting Orgs and Courses.
