How do I pass params to my devise_invitable controller?

Question

I have created an invitation controller that is quite vanilla:

class InvitationsController < Devise::InvitationsController
  def new
    binding.pry
  end
end

And I created a link that triggers that request like so:

<%= link_to "Invite #{@profile.name}", new_user_invitation_path(email: @profile.email), class: "btn btn-xs btn-primary" %>

The issue I am having is that when I get thrown into pry in that action, it doesn't show me that email parameter.

> params
=> <ActionController::Parameters {"controller"=>"invitations", "action"=>"new"} permitted: false>

How can I send params with that InvitationsControler#New action?

Answer 1

It turns out that new_user_invitation_path corresponds to a GET request to a new invitation object, which generates a new form.

The solution is to create another action in another controller then simply call it with a method: :post like so:

<%= link_to "Invite #{@profile.name}", invite_path(@profile), method: :post, data: { confirm: "Are you SURE you are ready to invite #{@profile.name}?"}, class: "btn btn-xs btn-primary" %>

That works like a charm.
