Sample exercises

Part 1

1. Add following models to plugin basic:
   1. resource with fields
      1. number - string identifier of resource
      2. quantity - quantity of resource
      3. product - related product from plugin basic
   2. transfer with fields
      1. resource - related resource
      2. quantity - quantity of product in transfer
      3. type - type of transfer (incoming or outgoing)
      4. status - status of transfer (planned or done)
      5. request date,
      6. the worker who filled the request
      7. confirmation date/worker.
2. Create views with list of resources and transfers
3. Create view with resource details:
   1. form will contains three inputs
      • number
      • product's lookup
      • quantity - disabled, because it is set using custom action
   2. expression will be used to generate window header
   3. window header will be displayed
4. Create view with transfer details:
   1. form will contains eight inputs
      • resource's lookup
      • quantity
      • type
      • status
      • requestWorker - disabled, because it is set using custom action
      • requestDate - disabled, because it is set using custom action
      • confirmWorker - disabled, because it is set using custom action
      • confirmDate - disabled, because it is set using custom action
   2. expression will be used to generate window header
   3. window header will be displayed
5. Add custom action on save for transfer model - it should automatically set the transfer's workers and dates. Workers will be set using the current logged user - the one who create request will be put into requestWorker, Afterwards the one who changes the status to done will be put into confirmWorker. If transfer has not been saved (id is null) it should set requests worker and date, if transfer's status is done it should set confirmation worker and date. This action should also change quantity of the related resources, when the transfer is done.
6. Add custom validation for transfer model - it should check if a resource has enough quantity for delivery transfer.
