For some reason, the page doesn't get updated after sending a message. It works only after refreshing the page manually. I have partially followed this tutorial http://railscasts.com/episodes/316-private-pub but something is not right. Here are my files:
app/controllers/main_controller.rb
class MainController < ApplicationController
def application
#messages = Message.all
end
end
app/controllers/messages_controller.rb
class MessagesController < ApplicationController
def create
#message = Message.create(message_params)
end
private
def message_params
params.require(:message).permit(:content)
end
end

I hope I have provided information enough. If not, please request more. Thank you in advance.
I think you're just missing this in your messages controller:
respond_to do |format|
format.js #calls create.js.erb
end
Some things I would try:
Make sure private_pub is actually running on the server. netstat -lntp will show all listening TCP sockets by number, along with the program running them. You should see a ruby or rails app listening on 9292.
Make sure port 9292 requests aren't being blocked by a firewall, either on the server or on your client. This will obviously depend on the OS on each.
Use the Developer Console of the client browser (for example in Chrome: F12, "Network" tab) to view the outgoing request to see what type of response it's getting. If that response is timing out, the request is never making it to your server.
If the request is indeed making it back, look for Javascript errors in the Developer Console.

I am trying to add the toastr gem to my Rails 6 project. I also have the devise gem installed.
I do not understand webpacker and how to make toastr-rails webpacker friendly.
I have read all the documentation. Don't tell me to read the documentation.
This is what I've tried:
yarn add toastr
Then in my assets/packs/application.js file, I added:
#import 'toastr'
And in my assets/stylesheets/application.scss file, I added:
*= require_toastr
Finally my layouts/application.html.erb has this code:
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<% unless flash.empty? %>
<script type="text/javascript">
<% flash.each do |f| %>
<% type = f[0].to_s %>
toastr['<%= type %>']('<%= f[1] %>');
<% end %>
</script>
<% end %>
<%= yield %>
</body>
</html>
I don't get the toast notifications.
I don't get any notifications.
But this code works on my Rails 4 project.
If you want to add toastr with toastr-rails gem, use asset pipeline instead of webpack.
Here are the steps to add toastr with the webpack.
Add toastr js with yarn
yarn add toastr
Require toastr in app/javascript/packs/application.js. I added it to the global to avoid errors
global.toastr = require("toastr")
Create app/javascript/stylesheets/application.scss file to import custom or library css files
Import toastr css in app/javascript/stylesheets/application.scss
#import 'toastr'
Import app/javascript/stylesheets/application.scss file in app/javascript/packs/application.js
import "../stylesheets/application"
I wrote a helper method for flash messages. Add this method to application_helper.rb or another helper
def toastr_flash
flash.each_with_object([]) do |(type, message), flash_messages|
type = 'success' if type == 'notice'
type = 'error' if type == 'alert'
text = "<script>toastr.#{type}('#{message}', '', { closeButton: true, progressBar: true })</script>"
flash_messages << text.html_safe if message
end.join("\n").html_safe
end
Add toastr_flash method to layouts/application.html.erb or wherever you want
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<%= yield %>
<%= toastr_flash %>
</body>
</html>
first you need to add toastr to your project
using yarn
yarn add toastr
using npm
npm -i toastr
after that you can see in your node_modules the file toastr (node_modules/toastr) inside that have the toastr.scss file and toastr.js file, well let's import it
app/assets/application.scss
#import "toastr/toastr";
app/javascripts/packs/application.js
toastr = require("toastr")
or
import toastr from 'toastr/toastr';
I've just created a test project and been reading about the assets pipeline. So far, the assets are being loaded but not applied, as if I go to localhost:3000/assets/application.css I see the style I've written but I don't see the rules applied to the DOM.
Rails version: 4.2.1
Ruby version: 2.2.0
The structure is the following:
app
--- assets
------ images
------ javascripts
------ stylesheets
------------ application.css
------------ todos.css
The content of application.css is the following:
/*
*= require_tree .
*= require_self
*/
The content of application.js the following:
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
The rails APP is very simple, as it's just a model (todo.rb), the controller for that model (todos_controller.rb) with the following content:
class TodosController < ActionController::Base
def index
#todos = Todo.all
end
end
Very simple, and for the view I'm using Slim templates with the following hierarchy:
app
--- views
------ todos
--------- index.slim
The content of application.html.erb is the following:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
And for the view:
.todos
- #todos.each do |todo|
.title = todo.title
.content = todo.content
Is there about the assets pipeline I'm missing? Thanks in advance.
Rename index.slim into index.html.slim.
P.S. convention over configuration
The TodosController must inherit from ApplicationController, not from ActionController::Base
class TodosController < ApplicationController
def index
#todos = Todo.all
end
end
I'm working on a simple ruby on rails application and I am getting the following error:
TypeError: Cannot read property 'process' of undefined (in/home/saasbook/Documents/projects/Bookkeeper/app/assets/stylesheets/application.css.sass)

There seems to be an issue with version 5.0 of the autoprefixer-rails gem. Try downgrading to 4.0.2.2.
https://github.com/ai/autoprefixer-rails/issues/47
This will pop up if you are using Node instead of RubyRacer as your JS runtime.
EDIT -
This has been fixed in the latest version of autoprefixer.
bundle update autoprefixer-rails
This has been fixed in the latest release of autoprefixer. Upgrade using the following command -
bundle update autoprefixer-rails
I'm stumped here...I want to add a small and minor CSS/JS detail to my app. I have an app where users can create many posts. I am trying to add the function where once a user hovers over the posts, the posts should trigger a nice background color. I've checked everything and I don't see what I am doing wrong.
I've set up a post.js.coffee file under my stylesheet directory. I've also added the css styling in my application.scss file. My application.js file is wired up to require some JS and in my views folder under my posts folder, I am iterating through #post in my index template which is where I want to activate the hover background trigger. Any help is greatly appreciated.

I get an error while trying to load any page:
ActionView::Template::Error (variable #fontAwesomeEotPath_iefix is undefined)
(in /app/assets/stylesheets/bootstrap_and_overrides.css.less)):
2: <html>
3: <head>

What I did before? Just run bundle update
Because of bootstrap update I will need to update bootstrap's assets:
rails g bootstrap:install -f
There are a new line in assets:
+#fontAwesomeEotPath_iefix: asset-path("fontawesome-webfont.eot#iefix");
This also happened to me. This is because, When you update your Bootrap gem, You should update Its js and less css. Do
rails g bootstrap:install -f
This will add a line to your app/assets/css/bootstrap_overrides.css.less file
like
#fontAwesomeEotPath_iefix: asset-path("fontawesome-webfont.eot#iefix");
