How to define a method called send in a Rails controller?

Question

I am trying to define a method send in my controller:

class InvoicesController < ApplicationController

  def send
  end

end

However, I am getting an error wrong number of arguments (2 for 0) when I do this.

So I assume that send is a reserved word in Rails?

What could be a possible workaround for defining a send method in my controller anyway.

Thanks for any ideas.

send is a built-in method in ruby. Choose another name. send_invoice, for example. Or create, if you want to be RESTful. — Sergio Tulentsev

You cannot call a method 'send' in ruby. Send is an Object method

send(*args) public

Invokes the method identified by symbol, passing it any arguments specified. You can use send if the name send clashes with an existing method in obj.

Send method

It is not a reserved word.

The reason you can't have a send method in a controller is that send is already a method on the ruby Object class.

However, coming at the question from a slightly different angle, the main reason I can see to have a specific name for a method in this case is to get that name in the routing so that you can have, e.g.: http://localhost:3000/invoices/send or for a RESTful resource /invoices/123/send.

In which case you could call the method whatever you like and add a route named send to point at your method.

So, in your controller:

class InvoicesController < ApplicationController

  def send_invoice
    ...
  end

end

Then in config/routes.rb:

get 'invoices/send', to: 'invoices#send_invoice'

Or for an invoices resource:

resources :invoices do
  member :send, to: :send_invoice
end

I would consider calling it post or deliver instead
