Menu
I am writing a chat page for a RoR site. I have it all worked out in HTML and I am trying to implement it with ajax. There is a form for submission of messages. the form tag reads <%= form_for(@chat, remote: true, :authenticity_token => true) do |f| %>
My entire view:
<!DOCTYPE html>
<html>
<head>
<title>Battleriskopoloy - Communications</title>
</head>
<body>
<br>
<div id="heading_1" align="center">
<br><span id="title"><strong>[ . . . Communications . . . ]</strong></span>
</div><br>
<div id="sidebar"><br>
<% $chat_users.each do |user| %>
<% user = User.find_by_username(user) %>
<%= button_to user.username, flop_chat_path(user), :class => "select", :method => :get %>
<% end %>
</div>
<div id="display">
<% $messeges.each do |i| %>
<% if i[1] == "from" %>
<p style="color:#000000; text-align:right; margin-right:5%;font-family:courier"><%= i[0] %></p>
<br>
<% else %>
<p style="color:#FF0000; text-align:left; margin-left:5%; font-family:courier"><%= i[0] %></p>
<br>
<%end%>
<%end%>
</div>
<div id="textfield">
<%= form_for(@chat, remote: true, :authenticity_token => true) do |f| %>
<%= f.text_field :content, id: "compose" %>
<br>
<br>
<%= f.submit "Send Messege", id: "submit" %>
<% end %>
</div>
</body>
</html>
The controller :
class ChatsController < ApplicationController
$messeges = Array.new(10, " ")
def new
$messeges = Array.new
if $ruser != nil
$messeges = Array.new
Chat.all.each_with_index do |i, index|
if i.recipient == current_user.id && i.sender == $ruser.id
$messeges.push([i.content, "to"])
end
if i.recipient == $ruser.id && i.sender == current_user.id
$messeges.push([i.content, "from"])
end
end
end
$chat_users = Array.new
User.all.each do |user|
if user != nil && current_user != nil
if user.game_id == current_user.game_id && user.id != current_user.id
$chat_users.push(user.username)
end
end
end
@chat = Chat.new
end
def create
if $ruser != nil
@chat = Chat.new(chat_params)
@chat.recipient = $ruser.id
@chat.sender = current_user.id
@chat.save
end
redirect_to "/comms/new"
end
def flop
$ruser = User.find(params[:id])
$messeges = Array.new
Chat.all.each_with_index do |i, index|
if i.recipient == current_user.id && i.sender == $ruser.id
$messeges.push([i.content, "to"])
end
if i.recipient == $ruser.id && i.sender == current_user.id
$messeges.push([i.content, "from"])
end
end
redirect_to "/comms/new"
end
private
def chat_params
params.require(:chat).permit(:content)
end
end
Additionally, I have <%= csrf_meta_tags %> in my application.html.erb
I had found some other things online about people getting the same error with rails 4 when switching from ajax to html submission but that seemed only to be because they didn't have the :authenticity_token => true parameter included. Any help is greatly appreciated.

By default authenticity_token is set to false. So you need to add this line in your application.rb
config.action_view.embed_authenticity_token_in_remote_forms = true
