|
* This operation have some known quirks that can only be addressed using this setup instead of `setupInlineCreateDefaults` |
|
33
|
|
|
* 1 - InlineCreateOperation must be added AFTER CreateOperation trait. |
|
34
|
|
|
* 2 - setup() in controllers that have the InlineCreateOperations need to be called twice (technically we are re-creating a new crud). |
|
35
|
|
|
* |
|
36
|
|
|
* Both problems are solved using this setup because it will only be called when InlineCreate route is requested, so even that we need to call |
|
37
|
|
|
* setup again (we are creating a "new" crud panel to show in modal), it will not affect other operation setups. |
|
38
|
|
|
* |
|
39
|
|
|
* The downside of it, and why we need this explanation note, is that using `setupInlineCreateOperation` |
|
40
|
|
|
* in your CrudController to override/configure this operation will not have the same behaviour as |
|
41
|
|
|
* other operations. |
|
42
|
|
|
* |
|
43
|
|
|
* Usually you would just `setupSomeOperation()` and add your own setup of the operation. In this specific case is a little bit different, |
|
44
|
|
|
* this code is the minimum needed to run the operation, and should be present if you override this method in your CrudController. |
