Any ideas?
Your issue is where you are placing your 'Jumbotron' code. Currently, you're hardcoding the word 'Jumbotron' like this:
<h1 style="text-align:center">Jumbotron</h1>
You should move this inside the code where you are iterating over the categories:
<% #categories.each do |category| %>
<h1 style="text-align:center"><%= category.category %></h1>
<% end %>
Keep in mind, if you have more than one category, this is going to give you multiple <h1> tags; one for each category.
On the index page you are looping through the categories <% #categories.each do |category| %> thus you should use category.category and not #category.category inside the block
I have an app that allows users to add albums they like to a database. Anyone can then come along and write a review for that album. Pretty simple.
I am running into a problem where an extra record appears to be created for the reviews on each album's show page. Every album, even if it has not ever been reviewed, has an additional, seemingly empty review being displayed when I use .each to display each review in the album show page. I want to get rid of that.
Here is an image of the problem. I have used CSS to highlight reviews in red. As you can see, there is an empty review at the bottom. When I inspect the review in question, it's raty title is "Not reviewed yet!"
Here is my albums_controller:
class AlbumsController < ApplicationController
before_action :set_album, only: [:show, :edit, :update, :destroy]
before_action :authenticate_user!, only: [:edit, :new, :update, :destroy]
def index
#albums = Album.all
if params[:search].nil?
#albums = Album.all.order(year: :desc).order(title: :asc).paginate(:page => params[:page], :per_page => 24)
else
#albums = #albums.where("albums.title || albums.year || albums.artist LIKE ?", "%#{params[:search]}%").order(year: :desc).order(title: :asc).paginate(:page => params[:page], :per_page => 24)
end
end
def show
if #album.reviews.blank?
#average_review = 0
else
#average_review = #album.reviews.average(:rating).round(2)
end
#review = #album.reviews.build
end
def new
#album = Album.new
end
def edit
end
def create
#album = current_user.albums.build(album_params)
respond_to do |format|
if #album.save
format.html { redirect_to #album, notice: 'Album was successfully created.' }
format.json { render :show, status: :created, location: #album }
else
format.html { render :new }
format.json { render json: #album.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #album.update(album_params)
format.html { redirect_to #album, notice: 'Album was successfully updated.' }
format.json { render :show, status: :ok, location: #album }
else
format.html { render :edit }
format.json { render json: #album.errors, status: :unprocessable_entity }
end
end
end
def destroy
#album.destroy
respond_to do |format|
format.html { redirect_to albums_url, notice: 'Album was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_album
#album = Album.find(params[:id])
end
def album_params
params.require(:album).permit(:title, :artist, :year, :cover)
end
end
Here is the album show page, which is where the extra review is being displayed:
<div class="row">
<div class="col-xs-10 col-md-6 col-md-push-3 col-xs-push-1 top bottom">
<%= image_tag #album.cover, class: 'show_image' %>

<p class="white">Average Review<div class="average-review-rating" data-score=<%= #average_review %>></div></p>
<% if user_signed_in? %>
<% if #album.user_id == current_user.id %>
<%= link_to 'Edit', edit_album_path(#album), class: 'grey' %>
| <%= link_to 'Delete', album_path, method: :delete, data: {confirm: "Are you sure?"}, class: 'grey' %>
<% end %>
<% end %>
<br /><br />
<h4>Reviews</h4>
<% if user_signed_in? %>
<p class="grey">Write a review</p>
<%= form_for [#album, #review] do |r| %>
<div class="form-group">

<% end %>
<% end %>
<br />
<% #album.reviews.each do |r| %>

<% end %>
<% end %>
<br /><br />
</div>
<% end %>
</div>
</div>
<script>
$('.review-rating').raty({
readOnly: true,
score: function() {
return $(this).attr('data-number');
},
path: '/assets/'
});
$('#rating-form').raty({
path: '/assets/',
scoreName: 'review[rating]'
});
$('.average-review-rating').raty({
readOnly: true,

Any help would be very appreciated!
The problem here is on the last line of your show method: #review = #album.reviews.build. This line not only creates a new Review instance and assigns it to #review, but it also adds that instance to the array in #album.reviews. So, in your view, when you iterate over #album.reviews, you will see all of the persisted reviews as well as the one new, not persisted review that was built with build.
The easiest way to fix this would be to add this line in your view:
<% #album.reviews.each do |r| %>
<% next unless r.persisted? %>
Another solution would be to associate the new review with the album, but not on the #album instance. In the controller:
#review = Review.new(album: #album)
I think it could be because of last line in show.
#review = #album.reviews.build
It builds an empty review.
I am trying to improve an exercice that I did on treehouse, the idea was to remake a little version of facebook thing, where users could publish statuses.
Now I want that a user can comment any statuses... And I am kinda lost...
The idea is to have all on the same page (if possible?, like on the real facebook)
So the comment form and the "displaying" content...
I hope anyone could help me :)
This is my github repository
I think I haven't understand how to call variables from a controller to another...
If someone could explain me with very easy words ... I am not native english speaker... so sometime it's difficult..
Here are the statuses part
controllers/statuses_controller/rb
class StatusesController < ApplicationController
before_filter :authenticate_user!, only: [:new, :create, :edit, :update]
before_action :set_status, only: [:show, :edit, :update, :destroy]
def index
#statuses = Status.all
#comments = Comment.all
end
def show
#status = Status.find(params[:id])
#comments = #status.comments.all
end
def new
#status = Status.new
#comment = #status.comments.build
end
def create
#status = Status.new(status_params)
#status.user = current_user
respond_to do |format|
if #status.save
format.html { redirect_to #status, notice: 'Status was successfully created.' }
format.json { render :show, status: :created, location: #status }
else
format.html { render :new }
format.json { render json: #status.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #status.update(status_params)
format.html { redirect_to #status, notice: 'Status was successfully updated.' }
format.json { render :show, status: :ok, location: #status }
else
format.html { render :edit }
format.json { render json: #status.errors, status: :unprocessable_entity }
end
end
end
def destroy
#status.destroy
respond_to do |format|
format.html { redirect_to statuses_url, notice: 'Status was successfully destroyed.' }
format.json { head :no_content }
end
end
private
def set_status
#status = Status.find(params[:id])
end
def status_params
params.require(:status).permit(:user_id, :content, :comments_attribute[:id, :status_id, :content])
end
end
models/status.rb
class Status < ActiveRecord::Base
belongs_to :user
has_many :comments
default_scope -> { order(created_at: :DESC)}
validates :content, presence: true,
length: {minimum: 2}
validates :user_id, presence: true
end
views/comments/_form.html.erb I create a render in my index below:
<% simple_form_for #status.comments do |f|%>
<%= f.input :content %>
<%= f.button :submit %>
<% end %>
view/statuses/index.html.erb
<div class="page-header">
<h1>All of the Statuses</h1>
</div>
<%= link_to "Post A New Status", new_status_path, class: "btn btn-success"%>
<br>
<br>
<% #statuses.each do |status| %>
<div class="status">
<div class="row">
<div class="col-xs-1 avatar">
<%= image_tag status.user.avatar.thumb if status.user.avatar?%>
</div>
<div class="col-xs-7">
<h4><%= status.user.full_name%></h4>
</div>
</div>
<div class="row">
<div class="col-xs-8">
<p><%= simple_format(status.content) %></p>
</div>
</div>
<div class="row">
<div class="col-xs-8">
<%= link_to time_ago_in_words(status.created_at) + " ago", status %>
<% if status.user == current_user %>
<span class="admin">
| <%= link_to "Edit", edit_status_path(status) %> |
<%= link_to "Delete", status, method: :delete, data: {confirm: "Are you sure?"} %>
</span>
<% end %>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<p>Comments</p>
<% #comments.each do |comment| %>
<%= comment.content %>
<% end %>
</div>
</div>
<div class="row">
<div class="col-xs-12">
<%= render "comments/form" %>
</div>
</div>
</div>
Now the comments part:
model/comment.rb
class Comment < ActiveRecord::Base
belongs_to :status
belongs_to :user
end
controllers/comments_controller.rb
class CommentsController < ApplicationController
def create
#comment = Comment.new(params_comment)
end
def index
#statuses = Status.all
#comments = Comment.all
#comment = Comment.find_by(params[:id])
end
private
def params_comment
params.require(:comment).permit(:content)
end
end
routes.rb
resources :statuses do
resources :comments
end
user.rb
that's a part of what I have in there
has_many :statuses
has_many :comments
your comments creation method should look like this:
#status = Status.find(params[:status_id])
#comment = #status.comments.create(comment_params)
#comment.user_id = current_user.id if current_user
#comment.save
So, I have a rails app that allows users to submit youtube links and rank the songs/links using the thumbs up gem.
However, users must physically copy and paste the link into the browser to listen to the song after the link is uploaded. For a better UX I'm going to use this gem to dynamically embed the YouTube video into my app once the users upload the link.
However, I'm not quite sure how this can be done?
I was thinkin' of doing something like this in the index:
<%= YouTubeAddy.extract_video_id('song.url)' %> <%= YouTubeAddy.youtube_embed_url('song.url') %> ?
or would it have to be in the controller? and if so how?
song#new.html.erb:
<%= form_for #song, :html => { :multipart => true } do |f| %>
<% if #song.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(#song.errors.count, "error") %> prohibited this song from being saved:</h2>
<ul>
<% #song.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>

YouTubeAddy.youtube_embed_url('song.url') generates a string of iframe tag, so it should be used in your view exactly where you want an embedded video to be placed. But note that you should return an html safe string. So in your view you have:
<%=raw YouTubeAddy.youtube_embed_url('song.url') %>
More about unescaping html.
Not sure why I seem to be getting this error as I have the appropriate amount of ends. The app was working - and then I installed devise and it went to hell. I un-installed devise to go back to the working version but now I seem to be getting the error shown below.
