Question

Let’s say I had a model that looked something like this:

class SomeModel

  def method(var1, var2) do
    do.something.with(var1)
    do.something.with(var2)
  end

end

Is it possible to write a form_for within a view in rails that would call method when the person hits submit, and pass values that are set in the input fields as arguments to that method? Sorry if this is basic, but I can’t seem to figure it out on my own.

Answer 1

form_for creates the html for a form. It does not handle the submit itself.
When the user presses submit, a method in the controller is called.

In the controller method, you can call your model method. It is the right place, because it is the controllers job to handle the input parameters and manage which model object to call. The input fields are accessible in the params hash in the controller.
