How to insert a devise_invitable route to invite a user to a specific project

Question

Problem

I use devise and devise_invitable gems in a project management web application. I successfully invite new users to the web application.

But I need to invite new users to a specific project and I can’t understand how to do this. I need a project ID as part of the route, so I can correctly connect the controller code.

Context

The corresponding routes.rb section is as follows:

 devise_for :users, :controllers => { :invitations => "invitations" } 

So:

• users/invitation/new works for new invitations.
• My own invitations_controller.rb overrides the default value of InvitationsController

• I have :projects as a resource that I use, for example

    resources :projects do resources :milestones, :task ... etc end 

(I think) I want to do something like this work:

 users/invitation/projects/4f3423d34323/new 

Answer 1

The current approach is to specify a route using devise_scope :

 devise_for :users, :controllers => { :invitations => "invitations" } devise_scope :user do match "/projects/:project_id/invitations/new", :to => "invitations#new", :via => "get", :as => "new_project_invitation" end 

This means that I can use:

Case 1: users/invitation/new (to invite a new user to a web application)

and

Case 2: projects/:project_id/invitations/new (to invite a new user to a web application + project)

invitations_controller#new checks for the presence of :project_id and invokes the appropriate behavior for case 1 or 2.
