5 Prevention of collisions

5.1 Before save model

To prevent the entry of the wrong parent identifier (for example, the new number that is a child in a subordinate chain of nested records):

Use static method checkNewParentId(Model $mainModel, int $newParentId... e.t.c)

Here are the required parameters:

$mainModel - current model record, in which the parent id will be changed for new value.

$newParentId - new parent id, which must be verified.

5.2 After delete model

To prevent breaks in the chain of subject submissions:

Use static method afterDeleteMainModel(Model $mainModel... e.t.c)

Here is the required parameter:

$mainModel - deleted model record.

This function will rebuild the chain.
