Customize Deeplinks

General

Deep links in PLANTA project allow you to execute user-defined actions directly via URL. For example, users can access a linked module directly from an email—without having to manually navigate the system.

Technical Implementation

Requirements

• Creation of a user-defined class that inherits from BaseProtocolAction.

Procedure

• Define a class by

  • generating a subclass of ppms.protocol.BaseProtocolAction,

• implement the execute() method,

• access URL parameters,

  • self.path_parameters for path segments and

  • self.query_parameters for query strings.

Example

from ppms.protocol import BaseProtocolAction, get_any_module_object  

class OpenCustomerModuleAction(BaseProtocolAction):  
    def execute(self):        
        module = get_any_module_object()        
        module.open_module('100000')  

Note

• Save the class, e.g. in customer/protocol.py.

Create Deeplinks

Procedure

• Create a new entry in the Deeplink module:

  • Set action to a user-defined URL (e.g. /special_module),

  • Set the Python function to the path to your Python class (e.g. customer.protocol.OpenCustomerModuleAction),

  • Set a checkmark in the Activated checkbox,

  • Define a Python ID to be able to reference this deeplink at a later point.

• After setup, calling <planta-web-client>/special_module opens module 100000.

Path and Query Parameters

Information

• PLANTA deeplinks support both path parameters and query parameters. Both can be used for filtering or navigating nested hierarchies.

Path Parameter

Details

• Used to clearly display hierarchical resources.

• Path parameters can be defined directly in the deep link URL using angle brackets < >:

  • e.g.: project/<pr_id>.

    • Using the RESTful URL design.

Query Parameter

Details

• Used for optional filters or additional modificators.

• Automatic availability without having to explicitly define a query parameter:

  • e.g.: project/4711?foo=bar

• The flexibility may also lead to longer URLs.

Error Handling

Note

• If a user attempts to access a non-existent deep link, an error message is displayed (text constant 002502). Deeplink actions must treat invalid user input respectively in their implementation.
