How can I know which was changes on a Select field using relationship()?
My edit form inside the resource is simple, using the
relationship() function for a BelongsToMany relationship
Forms\Components\MultiSelect::make('handle_departments')
->relationship('handle_departments', 'name')
I'm trying to create a history record after user made changes on the relationship, but couldn't get the information about the changes.
I looked into the EditRecord's lifecycle and seems it's can only be retrieved in beforeValidate hook
So, how can I know the old values and new values of this relationship in this hook? I'm thinking about creating a hidden field to get the values, do you have any other suggestion?2 Replies
the reason why it isnt dehydrated is so the model doesnt attempt to save it as a normal column, as we save relationships separately to the pivot table
you could make the select dehydrated() or use a model observer which gives you access to the relationship itself
Ah yes, we could observe the pivot table. Thank you very much.
