Rights management
For the separation of access to the interface of VC and its components, every widget contains information about the owner, its groups and access rights. Access rights are recorded, as adopted in OpenSCADA, as a triad: "{user}{group[,group1,groupN]}{other}", where each element consists of two attributes of the access, for which the following interpretation is adopted:
- r — the right to review the widget;
- w — the right to control over the widget.
In the development mode a simple scheme of accessing "root:UI|RWRWR_" is used, which means — all users can open and view the libraries, their components and projects, and all users of the group "UI" (user interfaces) can edit.
In the runtime mode the rights work, described in the interface components, which include the ability to inherit the owner and rights from the top to the bottom. Wherein, by default, the inheritance enabled for each widget, then they get the owner and the rights of the project. At the same time, the direct setting of the rights of the complex widget will propagate them to all components of this widget.
