Ruby on Rails Form is not Capturing Values of Radio Button - javascript

I have a form in the Ruby on Rails app, It has four radio buttons, three of the radio buttons have default values i.e 25, 50, and 75, the fourth radio button does not have a value, however when you click it, it displays an input field for entering any number, The form only picks the value of the input field but not the radio button values. I want the form to capture values that are checked in any of the radio buttons.
here are my form details:
<div class="row__form-control">
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 25, class: "radio_button25", :onclick=>"notification()" %>
€ <%= form.label :amount, 25 %>
</div>
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 50, class: "radio_button50", :onclick=>"notification()" %>
€ <%= form.label :amount, 50 %>
</div>
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 75, class: "radio_button75", :onclick=>"notification()" %>
€ <%= form.label :amount, 75 %>
</div>
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 0, class: "radio_custom", :onclick=>"custom()" %>
<%= form.label :custom %>
</div>
</div>
Here is my controller:
before_action :set_donation, only: %i[ show edit update destroy ]
# GET /donations or /donations.json
def index
#donations = Donation.all
end
# GET /donations/1 or /donations/1.json
def show
end
# GET /donations/new
def new
#donation = Donation.new
end
# GET /donations/1/edit
def edit
end
# POST /donations or /donations.json
def create
#donation = Donation.new(donation_params)
respond_to do |format|
if #donation.save
format.html { redirect_to donation_url(#donation), notice: "Donation was successfully created." }
format.json { render :show, status: :created, location: #donation }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: #donation.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /donations/1 or /donations/1.json
def update
respond_to do |format|
if #donation.update(donation_params)
format.html { redirect_to donation_url(#donation), notice: "Donation was successfully updated." }
format.json { render :show, status: :ok, location: #donation }
else
format.html { render :edit, status: :unprocessable_entity }
format.json { render json: #donation.errors, status: :unprocessable_entity }
end
end
end
# DELETE /donations/1 or /donations/1.json
def destroy
#donation.destroy
respond_to do |format|
format.html { redirect_to donations_url, notice: "Donation was successfully destroyed." }
format.json { head :no_content }
end
end
private
def set_donation
#donation = Donation.find(params[:id])
end
def donation_params
params.require(:donation).permit(:name, :email, :amount, :project_id)
end

It worked here:
config/routes.rb
Rails.application.routes.draw do
root "donations#new"
resources :donations, only: [:new, :create]
end
app/views/donations/new.html.erb
<%= form_with model: #donation, local: true, method: :post do |form| %>
<div class="row__form-control">
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 25, class: "radio_button25", :onclick=>"notification()" %>
€ <%= form.label :amount, 25 %>
</div>
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 50, class: "radio_button50", :onclick=>"notification()" %>
€ <%= form.label :amount, 50 %>
</div>
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 75, class: "radio_button75", :onclick=>"notification()" %>
€ <%= form.label :amount, 75 %>
</div>
<div class='row__form-control_amount'>
<%= form.radio_button :amount, 0, class: "radio_custom", :onclick=>"custom()" %>
<%= form.label :custom %>
</div>
<%= form.submit "Create Donation" %>
I created 2 records with 50 and 75 euros!

Check for current page in a js file to render out different partials

I have implemented a favorites system into my rails app, which works on the individual show page for the Tracks model. This is all handled through the Favorites controller, so I am attempting to use the same js file for both index and show pages. This is what I have tried so far. It works if I only have the show page material, the javascript doesn't work at all for either if I do it this way.
favorite.js.erb
<% if current_page?(track_path(#track)) %>
$("#favorites").html("<%= escape_javascript(render('tracks/favorites')) %>");
<% else %>
$("#favorites").html("<%= escape_javascript(render('albums/favorites')) %>");
<% end %>
the partial for tracks/favorites
<% if user_signed_in? && current_user.favorited?(#track) %>
<%= link_to image_tag('icons/heart_full.svg', width: 20), track_unfavorite_path(#track), method: :post, remote: true %>
<% else %>
<%= link_to image_tag('icons/heart_empty.svg', width: 20), track_favorite_path(#track), method: :post, remote: true %>
<% end %>
the partial for albums/favorites
<% if user_signed_in? && current_user.favorited?(track) %>
<%= link_to image_tag('icons/heart_full.svg', width: 20), track_unfavorite_path(track),
method: :post, remote: true %> <%= pluralize( track.favorites.count, 'favorite' ) %>
<% else %>
<%= link_to image_tag('icons/heart_empty.svg', width: 20), track_favorite_path(track),
method: :post, remote: true %> <%= pluralize( track.favorites.count, 'favorite' ) %>
<% end %>
Passing the instance variable as the parameter works for the show page, but trying to do it for the loop results is what is confusing me.
favorites_controller.rb
class FavoritesController < ApplicationController
before_action :authenticate_user!
before_action :find_track
def favorite
#track.favorites.where(user_id: current_user.id).first_or_create
respond_to do |format|
format.html { redirect_to #track }
format.js
end
end
def unfavorite
#track.favorites.where(user_id: current_user.id).destroy_all
respond_to do |format|
format.html { redirect_to #track }
format.js
end
end
private
def find_track
#track = Track.find(params[:track_id])
end
end
The view for Track show page is simple:
<div id="favorites">
<%= render 'tracks/favorites' %>
</div>
The view for the loop on the index page:
<% #tracks.each do |track| %>
<div class="track_thumbnail">
<% if track.avatar? %>
<%= link_to image_tag(track.avatar.url), track_path(track), width: 100, title: track.title %>
<% else %>
<%= link_to image_tag(track.user.avatar.url), track_path(track), width: 100, title: track.title %>
<% end %>
<%= link_to track.user.username, user_path(track.user) %>
</div>
<div class="track_overview">
<h2><%= link_to track.title, track_path(track) %><% if track.explicit == "explicit" %> (explicit)<% end %></h2>
<p class="description"><%= truncate(track.description, length: 160) %></p>
<div class="icons_container">
<div id="favorites">
<%= render 'albums/favorites', :track => track %>
</div>
</div>
</div>
<% end %>

comments not rendering with ajax in rails

I am try to render my comments with ajax in my rails app...but it is not working and the comments diplay just after I redirect the page...so the comment get created successfully but the problem is rendering comments with ajax and jquery!!!!
I have this lines in my application.html.erb:
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
and this require line in my application.js:
//= require jquery

<div class="box panel panel-default">
<%= render 'post', post: #post %>

</div>
<div class="comment-content">
<%= comment.content %>
</div>
</div>
<% end %>
and here is the create.js.erb under comments folder :
$('#comments_<%= #post.id %>').append("<%=j render 'comments/comment', post: #post, comment: #comment %>");
$('#comment_content_<%= #post.id %>').val('')
and my comments controller:
class CommentsController < ApplicationController
before_action :set_post
def index
#comments = #post.comment.all
end
def new
#comment = #post.comments.build(comments_params)
end
def create
#comment = #post.comments.build(comments_params)
#comment.user_id = current_user.id
if #comment.save
respond_to do |format|
format.html { redirect_to root_path }
format.js
end
else
flash[:alert] = "Check the comment form, something went horribly wrong."
render root_path
end
end
def destroy
#comment = #post.comments.find(params[:id])
#comment.destroy
flash[:success] = "Comment deleted :("
redirect_to root_path
end
private
def comments_params
params.require(:comment).permit(:content)
end
def set_post
#post = Post.find(params[:post_id])
end
end
I don't think this line is right -
<div class="comments" id= "comments_#{post.id}">
I think you need this
<div class="comments" id= "comments_<%= post.id %>">

Rails New Model Ajax Response

I'm trying to make a simple example on a new form to send the notice of success when creating a new item using ajax.
I'm reciving a response from the server with 500 internal error.
new.js.erb
$("#flash-messages").html("<%= notice %>")
new.html.erb
<h1>New Ajax</h1>
<%= form_for(#ajax, remote: true) do |f| %>
<div id="flash-messages" >
</div>
<% if #ajax.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#ajax.errors.count, "error") %> prohibited this ajax from being saved:</h2>
<ul>
<% #ajax.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
controller
def create
#ajax = Ajax.new(ajax_params)
respond_to do |format|
if #ajax.save
format.html { redirect_to #ajax, notice: 'Ajax was successfully created.' }
format.json { render :show, status: :created, location: #ajax }
format.js { redirect_to new_ajax_path, flash[:notice] = "Fudeu" }
else
format.html { render :new }
format.json { render json: #ajax.errors, status: :unprocessable_entity }
end
end
end
I have found why was bugging my code.
Just nee do remove the flash[:notice] to notice:
Now I`m looking into giving a lifetime to this flash, like 10s and it vanishs
When I have it working I post it here for other people that may strugle as me

How to display flash messages, on successful ajax, at the top of my page, without refreshing?

My bookmarks index page is essentially a single page application. When I submit the form for a new bookmark at the bottom of my page, I want the page to not have to refresh and display "Bookmark successfully created!" in the form of a flash message at the top of the page.
In my application.html.erb file, I am rendering flash messages:
<!DOCTYPE html>
<html>
<head>
<title>Text Me Later</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
<body>
<%= render partial: 'layouts/nav' %>
<% flash.each do |key, value| %>
<% if key == "notice" %>
<%= content_tag :div, value, class: "text-center alert alert-warning" %>
<% elsif key == "alert" %>
<%= content_tag :div, value, class: "text-center alert alert-danger" %>
<% else %>
<%= content_tag :div, value, class: "text-center alert alert-success" %>
<% end %>
<% end %>
<div class="container">
<%= yield %>
<%= debug(params) if Rails.env.development? %>
</body>
</html>
The create method in my bookmarks_controller:
def create
#bookmark = Bookmark.new bookmark_params
#bookmark.user_id = current_user.id
respond_to do |format|
if #bookmark.save
flash[:notice] = 'Bookmark was successfully created.'
format.html {
redirect_to user_bookmarks_path
}
format.json {
render json: #bookmark,
status: :created,
location: #bookmark
}
format.js {}
else
flash[:error] = "Bookmark could not be created."
format.html {
render :index
}
format.json {
render json: #bookmark.errors.full_messages
}
format.js {}
end
end
end
My bookmarks index.html.erbfile:
<h2>All of <%= current_user.first_name %>'s Bookmarks</h2>
<ul id="all-bookmarks">
<% #bookmarks.each do |bookmark| %>
<li class="bookmark-div">
<div><%= bookmark.title %></div>
<div><%= bookmark.image %></div>
<div><%= bookmark.description %></div>
<div><%= bookmark.location %></div>
<div><%= bookmark.time %></div>
<div><%= bookmark.date %></div>
<div><%= bookmark.created_at %></div>
<div><%= bookmark.updated_at %></div>
<div><%= bookmark.url %></div>
<div><%= link_to "Edit", [:edit, bookmark]%></div>
<div><%= link_to "Delete Bookmark", bookmark, :method => :delete, confirm: 'are you sure?'%></div>
<div><%= link_to "Add as a reminder" %></div>
</li>
<% end %>
</ul>
<h2>Add a bookmark below:</h2>
<div id="post-new-bookmark">
<%= simple_form_for [#user, #bookmark], :method => :post, remote: true do |f| %>
<% if #bookmark.errors.any? %>
<div id="errorExplanation">
<h2><%= pluralize(#bookmark.errors.count, "error") %> prohibited this post from being saved:</h2>
<% end %>
<%= f.input :title %>
<%= f.input :image %>
<%= f.input :description %>
<%= f.input :location %>
<%= f.input :date %>
<%= f.button :submit %>
<% end %>
</div>
create.js.erb:
$("<%= escape_javascript(flash[:notice]) %>").appendTo("#flash-notice")
$("<%= escape_javascript render(:partial => 'bookmarks/cbookmark', :locals => { :bookmark => #bookmark }) %>").appendTo("#all-bookmarks")
My question is: Why is the flash message on successful bookmark creation not displaying at the top of the page right after a successful creation? Shouldn't the flash message handling in my application.html.erbtake care of it? Could it be due to a syntax error in my bookmark controller?
I also have a question about flash.now vs flash. Is that relevant in this case since the bookmark submission is an AJAX action?

Ce ne pas possible avec le flash de Rails
--
The flash forms part of the session cookie that Rails populates between actions. This has been notoriously difficult to parse with Ajax, and indeed remains a difficult pattern to implement (how can Rails repopulate the session when your browser hasn't been refreshed).
The way to go about it is to pass the value through your ajax method, using flash.now. Good ref here (I wrote about it):
#app/controllers/bookmarks_controller.rb
class BookmarksController < ApplicationController
def create
#bookmark = Bookmark.new bookmark_params
#bookmark.user_id = current_user.id
respond_to do |format|
if #bookmark.save
flash.now[:notice] = 'Bookmark was successfully created.'
format.html { redirect_to user_bookmarks_path }
format.json { render json: #bookmark, status: :created, location: #bookmark }
format.js
else
flash.now[:error] = "Bookmark could not be created."
format.html { render :index }
format.json { render json: #bookmark.errors.full_messages }
format.js
end
end
end
end
Using flash.now should allow you to populate the flash through Ajax accordingly:
#app/views/bookmarks/create.js.erb
$("<%=j flash.now[:notice] %>").appendTo("#flash-notice")

Rails Ajax Not Reloading
