No route matches [GET] for put request to custom action - ruby-on-rails

Question

I have a users model and controller. I am trying to make a put and delete request to my controller where the put request is tied to users#allow and the delete request is suppose to be directed to users#destroy. I However keep on getting this error when I make the request:
No route matches [GET] "/users/1/allow"
I am also using devise for users and admin classes so that might have something to do with this error. Im not really sure. Here is my routes.rb:
Rails.application.routes.draw do
get 'users/index'
put 'users/:id/allow', :to => 'users#allow', :as=>:users_allow
delete 'users/:id/destroy', :to => 'users#destroy',:as => :users_destroy
devise_for :users
devise_for :admins
root 'website#show'
resources :tweets do
put '/pass', :to => 'tweets#pass',:as => :pass
put '/fail', :to => 'tweets#fail',:as => :fail
end
get '/to_json', :to=>'tweets#to_json'
end
Here is my users controller:
class UsersController < ApplicationController
before_action :find_user, only:[:allow,:destroy]
before_filter :authenticate_admin!
def index
#users = User.all
end
def allow
find_user.update(:edit_permission=>true)
redirect_to(:back)
end
def destroy
find_user.destroy
redirect_to(:back)
end
private
def find_user
#user = User.find(params[:user_id])
end
end
And here is my users view where I am calling from, users/index.html.erb:
<h1>Users#index</h1>
<p>Find me in app/views/users/index.html.erb</p>
<ul>
<% #users.each do |user|%>
<% if user.edit_permission == nil%>
<li style="color:red"> <%=link_to 'approve', users_allow_path(user), method: :put %> <%=link_to 'delete', users_destroy_path(user), method: :delete %><%= "#{user.name} #{user.email}"%> </li>
<% else%>
<li style="color:green"><%=link_to 'delete', users_destroy_path(user), method: :delete %><%= "#{user.name} #{user.email}"%> </li>
<% end%>
<%end%>
</ul>
I also want to add that when I go into the view and I do an inspect element in my browser for the link for the put request I do see this:
<a rel="nofollow" data-method="put" href="/users/1/allow">approve</a>

Answer 1

I would run rake routes to see your actual routes, because in your routes.rb you actually don't have a route that matches a get with users/:id/allow

Answer 2

#config/routes.rb
resources :users, only: [:index, :destroy] do
put :allow, action: :allow #-> url.com/users/:user_id/allow
end
#app/controllers/users_controller.rb
class UsersController < ApplicationController
def index
#users = User.all
end
def allow
user.update edit_permission: true
redirect_to :back
end
private
def user
User.find params[:user_id] #-> why return an instance var if you aren't going to use it
end
end
#app/views/users/index.html.erb
<ul>
<% #users.each do |user| %>
<% options = {} %>
<% options.allow = ["allow", "red", "put"] %>
<% options.destroy = ["destroy", "green", "delete"] %>
<% option = user.edit_permission ? options.allow : [options.allow, options.destroy] %>
<% option.each do |action,colour,method| %>
<%= link_to action, eval("users_#{action}_path(user)"), method: method, class: colour %><%= "#{user.name} #{user.email}") %>
<% end %>
<% end %>
</ul>

To fix your actual problem, you need to make sure you have your Rails UJS driver loaded:
#app/assets/javascripts/application.js
//= require jquery
//= require jquery_ujs
//= require_tree .
