Devise allow admins to delete users - ruby-on-rails

This seems to be a common issue, I have tried a couple solutions and am getting an unexpected issue. The goal is to create a page that admins can edit the permissions on and delete user accounts. routes:
devise_for :users, controllers: { registrations: 'users/registrations'}
get '/login', to: 'sessions#new'
match '/users', to: 'users#index', via: 'get'
match '/users/makeAdmin', to: 'users#makeAdmin', via: 'get', :as => :users_makeAdmin
match '/users/revokeAdmin', to: 'users#revokeAdmin', via: 'get'
match 'users/:id' => 'users#destroy', :via => :delete, :as => :admin_destroy_user
match 'users/:id' => 'users#show', via: 'get', as: :user
resources :users
users_controller.rb
class UsersController < ApplicationController
def index
end
def makeAdmin
#user = User.find(params[:id])
#user.update(admin: true)
redirect_to users_index_path
end
def revokeAdmin
#user = User.find(params[:id])
#user.update(admin: false)
redirect_to users_index_path
end
def show
#user = User.find(params[:id])
end
def destroy
#user = User.find(params[:id])
#user.destroy
if #user.destroy
redirect_to users_index_path, notice: "User deleted."
end
end
end
users/index.html.erb
<style>
.button_to {
display: inline;
}
.evenrow {
background-color: #eee;
}
</style>
<script type="text/javascript">
function alert() {
alert("The paragraph was clicked.");
}
</script>
<h1>All Users</h1>
<ul class="list-group" style="padding: 0em 10% 0em 10%;">
<li class="list-group-item" style="background-color: #428bca; border-color: #357ebd;; color: #fff;">
<div class="row">
<div class="col-md-3">
<b>User Email</b>
</div>
<div class="col-md-3">
<b>User Name</b>
</div>
<div class="col-md-1">
<b>Admin</b>
</div>
<div class="col-md-5">
<b>Controls</b>
</div>
</div>
</li>
<%#users = User.all%>
<% #users.each do |user| %>
<li class="list-group-item">
<div class="row">
<div class="col-md-3">
<%= user.email %>
</div>
<div class="col-md-3">
<%= user.name %>
</div>
<div class="col-md-1">
<%= user.admin %>
</div>
<div class="col-md-5">
<% if user.admin %><%= link_to 'Revoke Admin', users_revokeAdmin_path(id: user.id), class: "btn btn-primary btn-md" %><% else %><%= link_to 'Make Admin', users_makeAdmin_path(id: user.id), class: "btn btn-primary btn-md" %><% end %>
| <%= link_to "Destroy", admin_destroy_user_path(user), method: :delete, data: { confirm: "You sure?" }, class: "btn btn-primary btn-md" %>
</div>
</div>
</li>
<% end %>
</ul>
When I hit the destroy button for a user I get an error that says
Template is missing
Missing template users/show, application/show with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in: * "/home/student/SLP/rca/app/views" * "/home/student/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/devise-4.2.0/app/views"
I haven't seen this mentioned in any other questions dealing with this, any help is appreciated.

The reason you're hitting a no template error is because if #user.destroy is false since you've already destroyed the user in the line above. Therefore redirect_to users_index_path never happens and it's looking for a destroy template.
Change your code to:
def destroy
#user = User.find(params[:id])
if #user.destroy
redirect_to users_index_path, notice: "User deleted."
else
redirect_to users_index_path, flash: { error: "User could not be deleted." }
end
end

Issues with Newly Installed Devise Login (ActionController::UnknownFormat in RegistrationsController#create)

I just switched my app from a hand-made login system to use the Devise gem. I have used this gem with many apps before, but have never had this issue. All the views are implemented correctly and display when they should, but when I try to create a new registration I get the following error:
ActionController::UnknownFormat in RegistrationsController#create

When I attempt to log in, I also get a blank white screen that just says "You need to sign in or sign up before continuing."
I think these errors are related, but as I have had no experience with this set of errors with Devise I'm not 100% sure. Can anyone help me figure out what's going wrong here?

</div>
<% end %>
<%= render "devise/shared/links" %>
</div> <!-- columns box -->
</div> <!-- container -->
</div> <!-- overlap-tall-hero-image -->
Here's a supplemental registrations_controller for some added columns:
class RegistrationsController < Devise::RegistrationsController
private
def sign_up_params
params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :gender, :birthday, :dom_hand, :sport, :g_years, :g_rounds, :g_practice, :handicap, :g_score, :admin)
end
def account_update_params
params.require(:user).permit(:first_name, :last_name, :email, :password, :password_confirmation, :current_password, :gender, :birthday, :dom_hand, :sport, :g_years, :g_rounds, :g_practice, :handicap, :g_score, :admin)
end
end
And here's how it's reflected in my routes:
devise_for :users, :controllers => { registrations: 'registrations' }
It turned out that Devise autogenerated this for both registrations#new and sessions#new:
<%= simple_form_for(resource, as: resource_name, url: user_registration_path(resource_name)) do |f| %>
The error disappeared when I removed (resource_name) on each form.

Am I creating an undefined nil method?

Everything is working properly except for when I want to check if a post belongs to a user_id.
What I am basically trying to achieve is to hide the delete post button so that other users can't delete it.
I am still new to ruby on rails when I did my first project I added an if statement that checks whether it belongs to the user_id or not. Now I am trying to do the same but I keep on getting the NoMethodError
Profile code:
<div class="container">
<div class="row">
<% if user_signed_in? %>
<% if #post.user_id == current_user.id %>
<div class="col-md-5">
<%= render '/components/post_form' %>
</div>
<%end%>
<%end%>
</div>
</div>
Post controller:
class PostsController < ApplicationController
before_action :find_post, only: [:show, :edit, :update, :destroy]
#new post
def new

Form partial:
<%= simple_form_for #newPost do |f| %>
<%= f.label :content %>
<%= f.text_field :content, autofocus: true %>
<%= f.button :submit %>
<% end %>
replace this:
<div class="container">
<div class="row">
<% if user_signed_in? %>
<% if #post.user_id == current_user.id %>
<div class="col-md-5">
<%= render '/components/post_form' %>
</div>
<%end%>
<%end%>
</div>
</div>
with this:
<div class="container">
<% if user_signed_in? && #newPost.present? && #newPost.user_id == current_user.id %>
<div class="row">
<div class="col-md-5">
<%= render '/components/post_form' %>
</div>
</div>
<%end%>
</div>
notice in your controller you defined #newPost, but your view is trying to use #post which doesnt exist.
Also you may want to pass #newPost into the partial, like so:
<%= render '/components/post_form', object: #newPost %>

** also having problems with the Show view. i think its the delete action
*** also can you take a look at my form partial for the review submission? i'm basically trying to render have the text area rendered in the Show view, then once submited, appear below the text area.
I can add reviews and save them, but once submitted, I get an error. i go to rails console, and see that the reviews are saved -- but just curious if my logic is any good.

Edit path requires a model id to work, so you need to pass it:

to
<%= link_to "delete comment", game_review_path(review, review.game_id), method: :delete %>

ArgumentError in ConversationsController#show -- wrong number of arguments (3 for 1..2)

With the Messageable gem in my Ruby on Rails app, I can access the New Conversation page successfully and chose a user to send to, a title for the message, and of course the body of the message itself.
However, when I click the send button and the page reloads, I receive the following error message:
ArgumentError in ConversationsController#show
wrong number of arguments (3 for 1..2)
Extracted source (around line #4):
2
3 # Returns the Gravatar for the given user.
4 def gravatar_for(user, options = { size: 80 })
5 gravatar_id = Digest::MD5::hexdigest(user.email.downcase)
6 size = options[:size]
7 gravatar_url = "https://secure.gravatar.com/avatar/#{gravatar_id}?s=# {size}"
What could be causing this issue? I'm having so many issues with the New Relic tutorial for Messageable I've been following.. I'm not sure if this error perhaps indicates some problem with there being two seperate gravatar methods that were for two different functions & tutorials (users_helper.rb gravatar method is implemented for profile pictures, from the Hartl tutorial; application_helper.rb gravatar method is implemented for the Messageable new relic tutorial). I don't believe there is any collision between the two causing an error as I haven't been able to fix it yet, but it's a possibility(?)
Anyways, any solution to this problem would be greatly appreciated.

In your show template there is code:
<%= gravatar_for message.sender, 45, message.sender.name %>
Unfortunately you have defined gravatar_for in two helpers - one in your UsersHelper, and one in your ApplicationHelper.
It looks like the definition from UsersHelper takes precedence over ApplicationHelper's one. Try removing the one from UserHelper, so the proper method is called.
Good luck!
EDIT
You've mentioned you want to be able to customise the gravatar size, and it is possible with your current implementation of UsersHelper#gravatar_for. Change your code in show as follows:
<%= gravatar_for message.sender, { size: 45 } %>
Please note I removed the third argument so it doesn't cause any errors. Additionally I passed a hash with defined size.
This should do the trick!
Hope that helps!

NoMethod Error - Controller Actions fail to work randomly

I'm creating a ticket booking app as my sample project using Ruby on Rails 4.1. Three are three models - Events, Tickets and Bookings. Events have many tickets and bookings. Tickets have many bookings and they belong to events. Bookings belongs to events and tickets.
The bookings controller looks like:
class BookingsController < ApplicationController
before_action :authenticate_user!
def index
#event = Event.find(params[:event_id])
#bookings = #event.bookings.all
end
def new
#event = Event.find(params[:event_id])
#ticket = #event.tickets.find(params[:ticket_id])
#booking = Booking.new
end
def create
#event = Event.find(params[:event_id])
#ticket = #event.tickets.find(params[:ticket_id])
#booking = #event.bookings.create(booking_params)
#booking.ticket = #ticket
Stripe.api_key = Rails.configuration.stripe[:secret_key]
#token = params[:stripeToken]
#amount = #booking.total_amount
begin
customer = Stripe::Customer.create(
:email => #booking.email,
:card => params[:stripeToken]
)
charge = Stripe::Charge.create(
:customer => customer.id,
:amount => #amount,
:currency => "usd",
#:card => token
)
flash[:notice] = "Thanks for the order"
rescue Stripe::CardError => e
flash[:danger] = e.message
end
if #booking.save
BookingMailer.booking_confirmation_user(#booking).deliver
redirect_to [#event, #booking]
else
render 'new'
end
end
def show
#event = Event.find(params[:event_id])
#booking = #event.bookings.find(params[:id])
end
def destroy
#event = Event.find(params[:event_id])
#booking = #event.bookings.find(params[:id])
#booking.destroy
redirect_to event_bookings_path
end
private
def booking_params
params.require(:booking).permit(:buyer_name, :email, :mobile, :address, :order_quantity, :ticket_id)
end
end
The booking model:
class Booking < ActiveRecord::Base
#before_create :check_ticket_count
belongs_to :event
belongs_to :ticket
has_many :charges
def total_amount
ticket.ticket_price.to_i * order_quantity.to_i
end
def check_ticket_count
count = ticket.ticket_quantity.to_i - order_quantity.to_i
ticket.update_attribute(:ticket_quantity, count)
end
end
Ticket model:
class Ticket < ActiveRecord::Base
belongs_to :event
has_many :bookings
belongs_to :user
before_create :check_start_date
before_update :check_start_date
def check_start_date
if (self.booking_start_date >= DateTime.now) && (self.booking_end_date != DateTime.now)
self.status = 'Open'
else
self.status = 'Closed'
end
end
def maximum_tickets_allowed
(1..maximum_quantity.to_i).to_a
end
end
The Bookings Index Page:
<h2>All Bookings</h2>
<div class="row">
<div class="col-md-10">
<table class="table">
<thead>
<tr>
<th>Buyer Name</th>
<th>Email Address</th>
<th>Ticket Type</th>
<th>No. of Tickets</th>
<th>Amount</th>
<th></th>
</tr>
</thead>
<tbody>
<% #event.bookings.each do |booking| %>
<tr>
<td><%= booking.buyer_name %></td>
<td><%= booking.email %></td>
<td><%= booking.ticket.ticket_name %></td>
<td><%= booking.order_quantity %></td>
<td><%= number_to_currency(booking.total_amount) %></td>
<td><%= link_to "Delete", event_booking_path(#event, booking), method: :delete, data: { confirm: "Are you sure?" }, class: "btn btn-link" %></td>
<% end %>
</tr>
</table>
</div>
</div>
Bookings show page:
Thanks for your purchase!
<div class="row">
<div class="col-md-8">
<b>Name:</b><p><%= #booking.buyer_name %></p>
<b>No. of Tickets</b><p><%= #booking.order_quantity %></p>
<b>Ticket Tier</b><p><%= #booking.ticket.ticket_name %></p>
<b>Amount Paid:</b><p><%= number_to_currency(#booking.total_amount) %></p>
<p><% #booking.check_ticket_count %></p>
</div>
Now, my problem is bookings work perfectly. All the details are fetched, displayed and model methods executed properly. However, occasionally without even making one single change to these files, I get the "Action controller exception caught error - NoMethodError in Bookings#index" and "Action controller exception caught error - NoMethodError in Bookings#show". The culprit is always the ticket_name in booking.ticket.ticket_name and #booking.ticket.ticket_name where the error states that it's an undefined method.

The problem is it's the right field name. Why would the actions work most of the times and fail randomly at times without a single change in the code?
booking.ticket is probably blank
You can do
<td><%= booking.ticket.ticket_name rescue nil %></td>
or
<td>
<% unless booking.ticket.blank? %>
<%= booking.ticket.ticket_name %>
<% else %>
No Ticket
</td>
