I've tried to use if else statement, and display a link next to the message, when I submit a message, the link won't display, and I have to refresh the page. It seems like if else statement doesn't work in actioncable.

How to add auto scrolling when adding a post?

I have two models, Post and Comment, the validation message doesn't show up when creating a comment. the rest are working fine except the validation doesn't show up.

I have an issue when I submit an empty for the second time. If I submit the empty field for the first time, the validation displays, then if I submit again with empty field, the submit button is then disabled. How to solve that?

I'm using datepicker and turbo frame. The datepicker is broken when the frame is replaced. I'm doing turbo:load in javascript file, it works when navigating between pages, but it will be broken when the form is replaced. I'm thinking to initialize datepicker in stimulus controller but I'm not familiar with stimulus. There aren't many documentation on stimulus, any idea?

I'm creating a User, Role and UserRole. A user can create a list of roles, and from the new user form, there is a nested form which populate a list of roles created, then the user able to select a role and associated with the new user. I'm able to create a list of roles, but facing problem when creating a nested form in the new user view file.

Here are the models, kindly advise me if relationships are correct.

class User < ApplicationRecord
  has_one :user_role
  has_one :role, through: :user_role
end

class Role < ApplicationRecord
  has_many :user_role
  has_many :user, through: :user_role
end

class UserRole < ApplicationRecord
  belongs_to :user
  belongs_to :role
end

User controller. I'm not sure if my controller is correct:

def new
  @user = User.find_by_id(params[:id])
    @user = @current_user.account.users.new
  @user = @current_user.build_user_role
end

def create
    @user = User.find_by_id(params[:id])                
    @user = @current_user.account.users.create_with_password(user_params)
if @user.save
  redirect_to users_path
else
  render 'new'
end

private
def user_params
  params.require(:user).permit(:id, :email, :password, :password_confirmation, :admin, :owner, user_role_attributes: [:user_id, :role_id])
end

end

Below is new user form:

<%= form_for(@user, remote: true) do |f| %>

<%= f.text_field :email, class: "form-control", autofocus: true, autocomplete: "off" %>
<%= f.check_box :admin, class:"checkbox" %>
<%= f.check_box :owner, class:"checkbox" %>

<%= f.fields_for :user_role do |ff| %>
<!-- I don't know how to create a select dropdown to populate a list of roles that have been created -->
<% end %>             

<%= f.button "Create",  class: "btn btn-success" %>

<% end %>

I'm implementing Switchery button in my Rails app and Turbolinks is on. When I navigate to another page, and then click the back button, the button is being duplicated.

Here is my Javascript code:

$(document).on('turbolinks:load', function() {
var elem = document.querySelector('.js-switch');
var switchery = new Switchery(elem, {className:"switchery switchery-small"});
});

Html view:
<b>Assign as administrator?<span> <%= f.check_box :admin, class:"js-switch" %></span></b>

So how can i handle this problem ?

I'm implementing Switchery on my Rails app, and I'm also using Turbolinks. Everything works fine and the switchery is working except when I click to another page and then click the back button, the switchery icon actually duplicated and show twice. How do I destroy when navigating back to the page?

Here is the JavaScript code:

var ready;
ready = function() {
    var elem = document.getElementById('js-switch');
    var switchery = new Switchery(elem, {className:"switchery switchery-small"});

};
$(document).on('turbolinks:load', ready);

Hi Chris, I don't want to use Turbolinks in my app. Is there any way to replace the code?

I'm implementing ActionCable in my Rails app. I'm facing an issue with Registered Connection error. I'm using MongoID in my Rails app.

  class Connection < ActionCable::Connection::Base
   identified_by :current_user

def connect
  self.current_user = find_verified_user
  logger.add_tags "ActionCable", "User #{current_user.id}"
end

protected

def find_verified_user
 current_user = User.find_by(cookies.signed[:user_id])
  if current_user
    current_user
  else
    reject_unauthorized_connection
  end  
end

  end
end
