Permissions
Class permissions for an individual class define which users or groups can access the class, which fields can be read and or written, and filters specifying which instances of the class can be accessed.
 | To apply permissions defined in the permissions configuration, the Permissions Checking option must be selected under the class properties. |
When the permissions checking option is FALSE, no class-specific permissions will be applied and the class will be available to any user. Once permission checking is enabled, only users with explicit permissions defined in the permissions table will be able to access the class.
Each permission entry is defined by the following rules:
User Context Mask. A Context path or mask which resolves to a user or group of users. This mask defines the user or users on whom the permissions will be applied.
Columns. Data table with a row for each field in the class. Note the following:
Write permissions for a field require read permissions to be enabled for that field. A field cannot have write permissions enabled while read permissions are disabled.
The permission settings for each field are independent of one another. For example, one field could have only read permissions enabled, another field may have both read and write enabled, and yet another have neither read nor write permissions enabled.
Write permissions in this case include create, update, and delete operations.
Instance Filter. Data table of the instance filters type
 | If new fields are added to the class after permissions have been defined, the columns field must be updated for any existing permission entries. |
