Last commit: Wed Nov 18 00:18:10 2020 +0100	Jan Dankert	Refactoring Part 2: Removing all unnecessary methods in the action base classes.


     1 # And... Action!
     2 
     3 These action classes are the 'presenter' part in the [model-view-presenter](https://en.wikipedia.org/wiki/Model%E2%80%93view%E2%80%93presenter).
     4 
     5 
     6 Their mission is to
     7 - validate input data
     8 - calling the model
     9 - providing all data for the UI.
    10 
    11 ### View and Post
    12 
    13 Every HTTP-Request contains 3 parameters: 
    14 - `action`: The action pointing to an model object
    15 - `method`: The method
    16 - `id`    : The id of the model object. This is optional in some cases
    17 
    18 ### View and Post
    19 
    20 The parameter `method` and the HTTP method are deciding, which method is called.
    21 
    22 Example:
    23 `GET  /?action=example&method=foo` will call _ExampleFooAction::view()_.
    24 `POST /?action=example&method=foo` will call _ExampleFooAction::post()_.
    25 
    26 ### Contracts:
    27 - **no database requests are done here!** Database requests are only done by the model classes.
