Set User Role upon invite

[rtamburro]

I have followed the docs and every SO post on this and I cannot figure it out. I need an admin to set a User's role upon invite.

According to the docs, it should be as simple as adding this into app/controllers/users/invitations_controller.rb:

class Users::InvitationsController < Devise::InvitationsController
  before_action :configure_permitted_parameters
  
  protected
  
  # Permit the new params here.
  def configure_permitted_parameters
    devise_parameter_sanitizer.permit(:invite, keys: [:email, :role])
  end
end

I do this an nothing appears in app/views/users/invitations/new.html.erb. That looks like:

<h2><%= t "devise.invitations.new.header" %></h2>

<%= simple_form_for(resource, as: resource_name, url: invitation_path(resource_name), html: { method: :post }) do |f| %>
  <%= f.error_notification %>

  <% resource.class.invite_key_fields.each do |field| -%>
    <div class="form-inputs">
      <%= f.input field %>
    </div>
  <% end %>

  <div class="form-actions">
    <%= f.button :submit, t("devise.invitations.new.submit_button") %>
  </div>
<% end %>

My routes.rb file is structured as so:

Rails.application.routes.draw do
  resources :blocks
  devise_for :users, :controllers => {registrations: 'registrations', invitations: 'users/invitations'}
  resources :assignments
  resources :games
  resources :users, :only =>[:show]
  
  root "home#show"
end

I have tested that the email is sent out properly and can confirm it does. Any ideas on why I can't set the role in the new.html.erb file? The role field should be populating, but it doesn't.

You must change view invitations/new to add role field too. Default view include only invite_key_fields, which are fields needed to look for existing user, by default only email.

So you must change view to add new fields, and add these new fields to devise_parameter_sanitizer as you did. It's explained in README, https://github.com/scambra/devise_invitable#label-Strong+Parameters, you must add fields to sanitizer when you customize views adding more fields to form. Also, you don't need to override controller, you can add it to application controller.

I can't believe I never just tried adding that...thank you!
I think there should be an example in the docs of what a custom view might look like. A lot of research into my problem never showed anyone trying that and I think it would be a big help.

@rtamburro can you send PR improving that README section or adding a new one?

[rtamburro]

Yes, I will do that by end of tomorrow. Thanks again!
