How to validate in a model, data from a controller

Question

So I have some data that gets pulled from another rails app in a controller lets call it ExampleController and I want to validate it as being there in my model before allowi

Answer 1

You can pass the data from the controller as a parameter to the validation method in the model.

In your models/awizard.rb

def valid_for_step_one?(some_external_data)
  #validation logic here
end

So that in your controller, you can can call:

model.valid_for_step_one?(data_from_controller)

It would also be good if you can give a description of the data you are getting from the controller. How is it related to the model awizard?

Because another option is to set the external data as an attribute of the model. Then you can use it in your validation functions from there.
