So im working on a RoR app and would appreciate a bit of help with something. In this app, I've got a series of discussions, posted by users, with comments below, also posted by users. In terms of design, i thought it would be cool if each discussion would take up the entire screen with a button to the right of it. pressing this button would cause the view to move and reveal another discussion. Any suggestions about how I would go about doing this? heres the discussion partial I have currently. thanks!
<link href='http://fonts.googleapis.com/css?family=Titillium+Web:400,300' rel='stylesheet' type='text/css'>
<% content_for :script do %>
<%= javascript_include_tag 'hover_content' %>
<% end %>
<% #micropost = Micropost.new %>
<% #micropost.discussion_id = discussion.id %>
<li>
<div class = "intro-bar"><span class = "intro"><%=discussion.intro %></span></div>
<div class = "content-bar">
<span class = "content"><%= discussion.content %></span>
</div>
<input type='button' id='hideshow' value='hide/show'>
</li>
<span class = "timestamp">
Posted <%= time_ago_in_words(discussion.created_at) %> ago.
</span>
<% if signed_in? %>
<div class = "row">
<aside class = "span4">
<section>
<%= form_for(#micropost) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field">
<%= f.text_area :content, placeholder: "Post a comment" %>
</div>
<%= f.hidden_field :discussion_id%>
<%= f.submit "Break Up", class: "btn btn-large btn-breakup",:name => "break_up" %>
<%= f.submit "Stay Together", class: "btn btn-large btn-staytogether", :name => "stay_together" %>
<% end %>
</section>
</aside>
</div>
<% end %>
<div class = "comments">
<% discussion.microposts.each do |micropost| %>
<div class = 'comment-box'>
<li>
<div class = "comment-pic"></div>
<div class = "post-comment"><%= micropost.content%></div>
</li>
</div>
<% end %>
</div>
Your best bet would be a carousel.
For jQuery: http://sorgalla.com/projects/jcarousel/
(The "Special Examples" section has a text scroller which looks like what you want, but vertical)
For Prototype: http://code.google.com/p/prototype-carousel/

I am working on a simple website which has posts in forms of songs, now I have implemented like and dislike feature, but when I click on like/dislike it renders the numbers of likes/dislikes on all posts. And when I reload the page it returns them to normal. Now I would like it to change only the numbers for that particular post, without affecting the numbers on other posts?
My view for posts:
<div class="col-6">
<% for #s in #songs %>
<div class="card border-secondary mb-1">
<div class="card-header">
<div class="col-1">
<%= image_tag User.find(#s.user_id).user_image.url, :size=>"50x50" %>
</div>
<div class="col-11 text-muted">
<a href="/user/<%= User.find(#s.user_id).username %>" class="info-col">
<%= User.find(#s.user_id).username %>
</a>
- <%= #s.created_at.to_formatted_s(:short) %>
</div>
</div>
<div class="card-body">
<h4 class="card-title">
<%= #s.title %>
</h4>
<p class="card-text"><%= simple_format(#s.content) %></p>
</div>
<div class="card-footer text-muted">
<div class="col-12">
<div class="row">
<div class="col-3" id="song_like">
<%= render '/components/song_like' %>
</div>
<div class="col-3" id="song_dislike">
<%= render '/components/song_dislike' %>
</div>
<div class="col-4" id="song_comment">
<%= render '/components/song_comment' %>
</div>
</div>
</div>
</div>
</div>
<% end %>
</div>
The song_like partial has the following code:
<%= link_to like_song_path(#s.id, like: true), remote: true, method: :post do %>
<i class="fa fa-thumbs-o-up fa-lg" aria-hidden="true"></i>   <span class="songlikes">
<%= #s.thumbs_up_total %>
</span>
<% end %>
The song_dislike partial has the following code:
<%= link_to like_song_path(#s.id, like: false), method: :post, remote: true do %>
<i class="fa fa-thumbs-o-down fa-lg" aria-hidden="true"></i>   <span class="songdislikes">
<%= #s.thumbs_down_total %>
</span>
<% end %>
And my 'like' controller is like:
def like
#s = Song.find(params[:id])
#like = Like.create(like: params[:like], user: current_user, song: #s)
respond_to do |format|
if #like.valid?
format.html
format.js
else
format.html
format.js
end
end
end
This is how like.js.erb looks like:
$('.songlikes').html("<%= #s.thumbs_up_total %>");
$('.songdislikes').html("<%= #s.thumbs_down_total %>");
Here is the part of routes.rb file:
resources :songs do
member do
post 'like'
end
end
I am assuming there is some issue on rendering or jquery, but can't figure it out. Do You have any instructions?
EDIT: You should remove the redirect_to in your f.html?
This reloads the page - and the js will therefore not work.
An Ajax call is per definition not reloading the page.
If you remove those lines and try the following:
There's no new data in your jQuery.
You need a global attribute, so the view can find the data from your controller.
For example:
#like = ...
Then in your view you can add a local to be rendered:
$("#song_like").load("<%=j render partial: '/components/song_like', locals: {like: #like} %>");
But, you need to change your partial to be a partial. And change the variable to like so it will be rendered in the right way.
Hope it helps!
UPDATE
If you want to hit a specific song you can render it with each and then assign an id to your post's class
For example:
<% #posts.each do |post| %>
<div class="post-content">
... other stuff ...
<div class="likes like-post-<%= post.id %>">
.. number of likes
</div>
<%= link_to "Like", link_route_path(post) %>
</div>
<% end %>
# controller
# So you can use the id in your js view
#id = params[:id]
# view.js
$(".like-post-" + "<%= #id %>").html("<%= #s.thumbs_up_total %>");
Hope the idea helps.
change rendering like this:
<div class="col-3" id="song_like">
<%= render partial: '/components/song_like', locals: {s: #s, like: true} %>
</div>
then in partial:
<%= link_to like_song_path(s.id, like: like), method: :post, remote: true do %>
<i class="fa fa-thumbs-o-up fa-lg" aria-hidden="true"></i>   <%= s.thumbs_up_total %>
<% end %>
and in controller of like_song
should define
#s= Song.find(params[:id])
like = Like.create(like: params[:like], user: current_user, song: #song)
#like = !like.like # opposite to your current status
rest of the things good and then in like.js.erb
$('#songs_like').html("<%= escape_javascript(render partial: '/components/song_like', locals: { s: #s, like: #like } ) %>")
A bit of a confusing title.
I am trying to implement a bit of a reddit like comment system. So that you can view a Post and add a Comment to it which is polymorphic. Or, comment on another Comment.
My view looks like so:
<h2>Post:</h2>
<div class="well">
<p>
<strong>Title:</strong>
<%= #post.title %>
</p>
<% if #post.description %>
<p>
<strong>Description:</strong>
<%= #post.description %>
</p>
<% end %>
</div>
<% if current_user %>
<%= render "shared/comment_form" %>
<% else %>
<p>Log in to add comments</p>
<% end %>
<% if #post.comments.any? %>
<%= render "shared/comment_list" %> # Another comment_form inside of this partial
<% else %>
<p>No comments yet</p>
<% end %>
Inside of comment_list is another rendering of comment_form so that you can comment on a comment:
<h2>Comments</h2>
<ul>
<% #post.comments.each do |co| %>
<li><%= co.body %></li>
<%= render "shared/comment_form" if current_user %>
<% end %>
</ul>
Finally, my comment form itself:
<div id="comment-form" class="form-group">
<%= form_for #comment, remote: true, url: post_comments_path(#post) do |f| %>
<%= f.text_area :body, required: true, rows: 5, class: "form-control" %>
<%= f.hidden_field :commentable_id, :value => #post.id %>
<%= f.hidden_field :commentable_type, :value => #post.class.name %>
<%= f.hidden_field :user_id, :value => current_user.id %>
<br>
<%= f.submit class: "btn btn-primary" %>
<% end %>
</div>
<span id="add-comment">Add a comment</span>
And the Jquery code that acts on the comment_form:
$(document).on('turbolinks:load', function() {
$("#comment-form").hide();
$('#add-comment').click( function() {
$("#comment-form").fadeToggle("fast");
($("#add-comment").text() === "Cancel") ? $("#add-comment").text("Add comment") : $("#add-comment").text("Hide");
});
});
My question is:
How could I separate these divs so that Jquery doesn't fire on all instances of id="comment-form? I would like to pass in an erb tag like <%= #post.class.name %><%= #post.id %>, but again, keep the variable universal. Then, how could I implement that unique id name in my JQuery code.
Edit: I got one part of my question solved. I left the rest of what I wasn't able to do up for everyone to see.
You could use prev() like this:
$(document).ready(function() {
$('.comment-form').hide();
$('.add-comment').click( function(event) {
// Store the button which has just been clicked on a variable
var eventTarget = $(event.target);
// Find the previous element with the #comment-form and id and toggle it
eventTarget.prev('.comment-form').fadeToggle('fast');
// Use the eventTarget Again
(eventTarget.text() === 'Cancel') ? eventTarget.text('Add comment') : eventTarget.text('Cancel');
});
});

I'm trying to show a list of "Interests" that users can "follow" by clicking on a button associated with the Interest's image. Upon clicking the button to follow an Interest, the Interest (and it's corresponding image) should disappear from the list.
I'm using a hide function in a create.js.erb file called upon by a Relationship controller when the follow button is clicked, but the function will only hide the first Interest in the series of Interests--NOT the Interest the user clicked on that needs to disappear. So there has to be a better way to set this up, but I cannot, for the life of me, figure it out. Here's my current setup:
My Controller
class StaticPagesController < ApplicationController
def home
#user = current_user
#city = request.location.city
#interests = Interest.all
end
The home page
<%= render #interests %>
The partial
<div id="follow_form">
<div class="four columns portfolio-item interests">
<div class="our-work">
<a class="img-overlay">
<%= image_tag interest.image_path %>
<div class="img-overlay-div">
<h4><%= interest.name %></h4>
</br>
<h5>Placeholder
</br>
<%= interest.desc %></h5>
<%= form_for(current_user.relationships.build(followed_id:
interest.id), remote: true) do |f| %>
<div><%= f.hidden_field :followed_id %></div>
<%= f.submit "I'm interested", class: "b-black" %>
<% end %>
</div>
</a>
<h3><%= interest.name %><span>features info</span></h3>
</div>
</div>
</div>
And the create.js.erb that's called upon by a Relationships controller when you click the button:
$("#follow_form").hide();
UPDATE
Here is the Relationships controller for additional clarification
def create
#interest = Interest.find(params[:relationship][:followed_id])
current_user.follow!(#interest)
respond_to do |format|
format.html { redirect_to(root_url) }
format.js
end
end
You need to provide something to differentiate the different "follow_forms" that you have on the same page. Otherwise, jQuery will just select the first element and only remove that one.
One idea of how to do this would be to append the "interest.id" to the end of the follow_form id
Update your partial to be like this (assuming your partial is called and located in /app/views/interests/_follow_form.html.erb:
<div id="follow_form<%="#{interest.id} %>">
<div class="four columns portfolio-item interests">
<div class="our-work">
<a class="img-overlay">
<%= image_tag interest.image_path %>
<div class="img-overlay-div">
<h4><%= interest.name %></h4>
</br>
<h5>Placeholder
</br>
<%= interest.desc %></h5>
<%= form_for(current_user.relationships.build(followed_id:
interest.id), remote: true) do |f| %>
<div><%= f.hidden_field :followed_id %></div>
<%= f.submit "I'm interested", class: "b-black" %>
<% end %>
</div>
</a>
<h3><%= interest.name %><span>features info</span></h3>
</div>
</div>
</div>
This way each follow_form will have a unique ID attached to it. Then you can loop through your interests and call a partial on each one like this:
home page:
<% #interests.each do |interest| %>
<%= render 'interests/follow_form', :interest => interest %>
<% end %>
create.js.erb
$("#follow_form_<%= "#{#interest.id}" %>").hide())
Your controller action can stay the same.
Alright, I'm a JS / JQuery / Coffeescript noob. This is probably easy points for someone.
Having successfully implemented RBate's Nested Form Model railscast, I am attempting to reproduce this in a simpler model: Chapters have many counties.
I have a chapters.js.coffee file with the following code:
jQuery ->
$('form').on 'click', '.remove_fields', (event) ->
$(this).prev('#destroy').val('1')
$(this).closest('fieldset').hide()
event.preventDefault()
This code works just fine in the other model. But not here.
_chapters_form.html.erb:
<div class="row span12">
<%= form_for(#chapter) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="span2"><strong>Chapter name:</strong></div>
<div class="span6"><%= f.text_field :name %></div>
<div class="span2"><strong>Chapter Number:</strong></div>
<%= f.number_field :chapter_num, class: "span2" %>
</div>
<div class="row span12">
<div class="span12">
<%= f.fields_for :counties do |builder| %>
<%= render 'county_fields', f: builder %>
<% end %>
</div>
<% if f.object.new_record? then link = 'Add the Chapter' else link = 'Update Chapter' end %>
<%= f.submit "#{link}", class: "btn btn-large btn-primary" %>
<%= link_to "Cancel", chapters_path, class: "btn btn-large btn-primary" %>
<% end %>
</div>
and:
_county_fields.html.erb:
<fieldset>
<div class="well span12">
<div class="row span12">
<div class="span3">County Number: <br /><i>(6-digit FIPS code)</i></div>
<div class="span2"><%= f.number_field :county_num %></div>
<div class="span2">County Name:</div>
<div class="span5"><%= f.text_field :name %></div>
</div>
<div class="row span12"><hr></div>
<div class="row span12">
<div class="span6">Move to new Chapter:</div>
<div class="span6"><%= select(:county, :chapter_id, Chapter.all.collect {|c| [c.name, c.id]}) %></div>
</div>
<div class="row span12">
<div class="pull-right">
<%= f.hidden_field :_destroy, id: "destroy" %>
<%= link_to "remove county", "#", class: "remove_fields" %>
</div>
</div>
</div>
</fieldset>
There are no errors in the JS. Again, noob speaking, but it doesn't seem that the JS is getting called. Clicking <%= link_to "remove county", "#", class: "remove_fields" %> just adds the # to the URI.
What am I doing wrong?
As requested, the HTML in a fiddle which doesn't work either.
Your HTML is broken. You open a div before the form element, then close it before you close the form. If you move the form element up to just inside the container div, it works.
<body>
<div class="container-fluid">
<form accept-charset="UTF-8" action="/chapters/7" class="edit_chapter" id="edit_chapter_7" method="post">
<div class="row-fluid">
...
</div>
</form>
</div>
</body>
You should take more care in the indenting of your HTML to help avoid this sort of simple mistake. Code format matters.
The page on which they appear - regardless of how they are rendered - must be an action of the chapters_controller for chapters.js.coffee to be included. My bet is that the script is not being included at all, as the code looks fine. Check out the pages you are having issues with with this code:
jQuery ->
console.log "included chapters.js.coffee"
$('form').on 'click', '.remove_fields', (event) ->
console.log "clicked .remove_fields"
$(this).prev('#destroy').val('1')
$(this).closest('fieldset').hide()
event.preventDefault()
Also, post up the rendered HTML in your question
I'm trying to use tabifier in my rails app so I have:
<%= stylesheet_link_tag "example", "example-print" %>
<%= javascript_include_tag 'tabber.js' %>
<script>
/* Optional: Temporarily hide the "tabber" class so it does not "flash"
on the page as plain HTML. After tabber runs, the class is changed
to "tabberlive" and it will appear. */
document.write('tabber{display:none;}');
</script>
<div class="tabber">
<div class="tabbertab">
<h2>Tab 1</h2>
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put }) do |f| %>
<%= devise_error_messages! %>
<div><%= f.label :peeruser %><br />
<%= f.select :peeruser, [['Not yet','not yet'],['Beginner','beginner'],['Intermediate','intermediate'],['Expert','expert']] %></div>
<div><%= f.label :discipline %><br />
<%= f.text_field :discipline %></div>
<div><%= f.label :course %><br />
<%= f.text_field :course %></div>
<div><%= f.label :concept %><br />
<%= f.select :concept, [['Yes','yes'],['No','no']] %></div>
<div><%= f.submit "Continue" %></div>
<% end %>
</div>
<div class="tabbertab">
<h2>Tab 2</h2>
<p>Tab 2 content.</p>
</div>
<div class="tabbertab">
<h2>Tab 3</h2>
<p>Tab 3 content.</p>
</div>
</div>
<%= link_to "Back", :back %>
And I can't figure out why it's not loading correctly like the examples:
http://www.barelyfitz.com/projects/tabber/
I put the javascript if under public->javascripts and the css under public->stylesheets - like it just shows the text, none of it is linkable and it displays all the form information.
not exactly a solution, but why not use a more popular and feature-rich library ?
JqueryUI features a nice and simple way to implement tabs.
Once the lib is loaded, all you will have to do is
<script>
$(function() {
$( ".tabber" ).tabs();
});
</script>
then add some links, reclass all your divs and bam ! instant tabs.
Plus, you have all the Jquery Lib, which is pure awesomeness.
Turns out I had not put the css and js in the assets folder which was causing the problem.
