A server module that provides user authentication and role based authorisation for server functions.
You will need to setup the Users and Data Table services in your app:
Ensure that you have added the ‘Users’ service to your app
- In the ‘Data Tables’ service, add:
a table named ‘permissions’ with a text column named ‘name’
a table named ‘roles’ with a text column named ‘name’ and a ‘link to table’column named ‘permissions’ that links to multiple rows of the permissions table
a new ‘link to table’ column in the Users table named ‘roles’ that links to multiple rows of the ‘roles’ table
Users and Permissions
Add entries to the permissions table. (e.g. ‘can_view_stuff’, ‘can_edit_sensitive_thing’)
Add entries to the roles table (e.g. ‘admin’) with links to the relevant permissions
In the Users table, link users to the relevant roles
The module includes two decorators which you can use on your server functions:
Checks that a user is logged in to your app before the function is called and raises an error if not. e.g.:
import anvil.server from anvil_extras.authorisation import authentication_required @anvil.server.callable @authentication_required def sensitive_server_function(): do_stuff()
Checks that a user is logged in to your app and has sufficient permissions before the function is called and raises an error if not:
import anvil.server from anvil_extras.authorisation import authorisation_required @anvil.server.callable @authorisation_required("can_edit_sensitive_thing") def sensitive_server_function(): do_stuff()
You can pass either a single string or a list of strings to the decorator. The function will only be called if the logged in user has ALL the permissions listed.
Notes: * The order of the decorators matters. anvil.server.callable must come before either of the authorisation module decorators.
