Answer 1

I think you want to be able to have 1 form that saves both the main object and all of the child objects. If not, disregard.

In rails, this is named "nested_attributes"

you'll add this to your model:

accepts_nested_attributes_for :quotes
# assuming you have 
has_many :quotes

and then in your form view:

<% form.fields_for :quotes do |child_form| %>
  <%= child_form.text_field :name %>
<% end %>

Honestly if it deals with params, it's probably a good idea to put that type of logic in the controller, lest you muddle the responsibilities of the model and controller.

That is, in the controller:

if @foo.save
  # Update line_items using params[:quotes]
end

Answer 3

If you're trying to use the params hash in your model, you are violating principles of MVC. The model should stand alone with arguments. If you are trying to do the following:

# controller
Model.foo

# model
def foo
  params[:bar].reverse!
end

You should do the following instead:

# controller
Model.foo(params[:bar])

# model
def foo(foobar)
  foobar.reverse!
end
