Calling External Model Methods in Rails

I have a two models, A and B where A has_many B.

In the A model, I have a public method that loops through all of the associated B objects and updates database fields in each of them. I would like to have the methods in B and run just the loops in A, but they do not appear to be saving correctly. Is there something wrong with this approach?

Here's an example of the methods:

def update_fields # A Method
  self.b.each do |b|
    b.b_method
  end
end

def b_method # B Method
  self.field = '5'
  self.save
end

Running this type of code, nothing is saved to the database and the output isn't updated.

How can I accomplish this type of thing? Or, does all the logic need to be in the A controller, even though it's dealing with B fields?

Solution

  • It ended up being a problem with the validations, so the general approach worked.
