Interface IPermissionRuleStore

Defines a store for retrieving permission rule filters based on user roles.

Namespace: DataWeb.Authorization

Assembly: DataWeb.Core.dll

Syntax

public interface IPermissionRuleStore

Remarks

This interface provides data access layer functionality for permission rules. It generates visibility filters for different contexts (list views vs. user-specific views) based on the user's assigned roles. Implementations typically query a rules database or configuration store to determine what data a user can access.

Properties

Name

Gets the name of the permission rule store.

Declaration

string Name { get; }

Property Value

Type	Description
string

Methods

GetListVisibleFilter(string, List<string>)

Retrieves a filter expression for a list view based on the specified table name and user roles.

Declaration

string GetListVisibleFilter(string tableName, List<string> userRoles)

Parameters

Type	Name	Description
string	tableName	The name of the table for which the filter is being requested.
List<string>	userRoles	A collection of the user's role identifiers that determine permission rules.

Returns

Type	Description
string	A filter expression string compatible with the data store (e.g., SQL or LINQ format). An empty string indicates no filtering (user can access all records). Returns null if the table is not recognized.

Remarks

This method is used for "list view" contexts where users browse records in a table. The filter restricts which records are visible based on the user's roles and associated permission rules.

GetUserVisibleFilter(string, List<string>)

Retrieves a filter expression for a user view based on the specified table name and user roles.

Declaration

string GetUserVisibleFilter(string tableName, List<string> userRoles)

Parameters

Type	Name	Description
string	tableName	The name of the table for which the filter is being requested.
List<string>	userRoles	A collection of the user's role identifiers that determine permission rules.

Returns

Type	Description
string	A filter expression string compatible with the data store (e.g., SQL or LINQ format). An empty string indicates no filtering (user can access all records). Returns null if the table is not recognized.

Remarks

This method is used for "user view" contexts where data is presented from a user-centric perspective. The filter may differ from GetListVisibleFilter(string, List<string>) based on the specific business rules for user views.
