Fields with validation

Need Help
1

Hi,

I have some models like so:

items (id, name)

attributes (id, name, datatype)

items_attributes (id, item_id, attribute_id, value)

I want to create attributes and assign types to it like decimal, varchar and such

Then when storing the _joined data. I want to perform validation on the joined data.

I want to store the validation type in database under attributes (attributes.datatype)

Then when a save is performed there is validation based on the information stored in attributes table.

How would I go about doing this? I need to use an event beforeSave and then create validation rules?

Any suggestions or examples of how this can be done?

I think open documentation: “Adding your own Validation Methods” it helps.
