I have used the acts as votable gem to like pins. Now I want a view (my favorites) with all the pins a user has liked. I get stuck in making this happen.
If have this in my pins controller file:
def my_favorites
#pins = current_user.pins
end
def like
#pin.liked_by current_user
redirect_to :back
end
def unlike
#pin.unliked_by current_user
redirect_to :back
end
And this in my favorites view:
<% if user_signed_in? %>
<h1>Mijn favoriete recepten</h1>
<p>Bekijk hier jouw <b> nummer </b> favoriete recepten die jij lekker vindt.</p>
<div id="pins" class="transitions-enabled">
<% #pins.each do |pin| %>
<div class="box panel panel-default">
<div class="panel-body">
<b>Recept: </b>
<p><%= link_to pin.description, pin_path(pin) %></p>
<b>Toegevoegd door: </b>
<p><%= link_to image_tag(pin.user.image_file_name), pin %></p>
<div class="actions">
<%= link_to like_pin_path(pin), method: :put, remote: true, class: "btn btn-default" do %>
<span class="glyphicon glyphicon-heart"></span>
Vind ik lekker!!!!
<% end %>
<%= link_to unlike_pin_path(pin), method: :put, remote: true, class: "btn btn-default" do %>
<span class="glyphicon glyphicon-remove"></span>
Niet mijn smaak
<% end %>
</div>
</div>
</div>
<% end %>
</div>
<% else %>
<%= render 'pages/login' %>
<% end %>
Thanks in advance for your help!!
I have done something similar:
<% if user_signed_in? %>
<% #pins.each do |pin| %>
<% if current_user.voted_for? pin %>
That should be at the top of the file
I have changed the pins controller in the following and now it is working:
def my_favorites
#pins = current_user.find_liked_items
end
Thanks for your help!

so my question is how can i enable this piece of code only when i want? I have multiple pages and some pages i need to remove that piece of code.
This is my current partial _navbar.html.erb and div.spotlight is the piece of code i need to disable in some pages
<div class="container">
<nav class="logonav">
<div class="row">
<div class="col50"><span class="logo"></span>
<h2>Musicus</h2>
<p>De ti para o mundo</p>
</div>
<% if user_signed_in? %>
<div class="col50">
<%= link_to 'Logout', destroy_user_session_path, class: 'ui-btn btn-normal', method: :delete %>
</div>
<% else %>
<div class="col50">
<%= link_to new_user_registration_path, class: 'ui-btn btn-accent' do %>
<span class="icon-add-user"></span> Criar Conta
<% end %>
<%= link_to new_user_session_path, class: 'ui-btn btn-normal' do %>
<span class="icon-login"></span> Login
<% end %>
</div>
<% end %>
</div>
</nav>
<div class="spotlight">
<%= yield :other_message %>
<%= render 'search' %>
<%= yield :primary_message %>
</div>
<%= yield :other_nav %>
</div>
You can use a simple if statement:
<% if show_spotlight %>
<div class="spotlight">
<%= yield :other_message %>
<%= render 'search' %>
<%= yield :primary_message %>
</div>
<% end %>
I have a blog rails app where users can comment on an article and the article author can message the user directly from the comment for which i have added a send message button, i am using mailbox for getting the message option, everything is working but the problem is when there are multiple comments the message button also get multiplied, but i don't want that what i am trying to have is one message button for each comment.
This is what am getting right now:
my code
<div id="comments">
<h2 class="comment_count">
<%= pluralize(#shipment.comments.count, "Bid") %>
</h2>
<% #comments.each do |comment| %>
<div class="comment">
<li class="round-image-50"><%= image_tag(current_user.avatar.url(:thumb)) %></li><h6 class="username"><strong><font style="text-transform: capitalize;"><%= comment.user.full_name %></strong></font></h6>
<div class="shipment">
<p class="content">
<div class="text-center left col-md-4">
<%= comment.content %>
</div>
<% if #shipment.user == current_user %>
<% #shipment.comments.each do |comment| %>
<%= link_to 'Send Message', new_conversation_path(recipient_id: comment.user_id), class: "btn btn-default btn-xs" %>
<% end %>
<% end %>
</p>
</div>
</div>
<% end %>
<%= render "comments/form" %>
</div>
Change this:
<% if #shipment.user == current_user %>
<% #shipment.comments.each do |comment| %>
<%= link_to 'Send Message', new_conversation_path(recipient_id: comment.user_id), class: "btn btn-default btn-xs" %>
<% end %>
<% end %>
to
<% if #shipment.user == current_user %>
<%= link_to 'Send Message', new_conversation_path(recipient_id: comment.user_id), class: "btn btn-default btn-xs" %>
<% end %>
PS: I assumed that #comments is same as #shipment.comments from your shown code
The error output is:
undefined method `total_pages' for #<Review:0x007fe460871f08>
Movie#Show:
def show
#review = #movie.reviews.paginate(page: params[:page], per_page: 6).order('created_at DESC').build
end
I set #movie via before_filter.
My view:
<% if #movie.now_playing %>
<% if #movie.reviews.any? %>
<% #movie.reviews.each do |review| %>
<div id="each_review_container">
<span><%= link_to #movie.creator.name, user_path(#movie.creator) %> | </span>
<span id="time"><%= review.created_at.try(:strftime,'%b %d, %Y') %></span>
<p>Rating: <%= review.rating %>/10</p>
<p><%= review.content %></p>
</div>
<% end %>
<div class="digg_pagination"><%= will_paginate #review %></div>
<% else %>
<span id="review_message">No Reviews yet!</span>
<span id="add_new_review_link"><%= link_to 'Add New Review', new_movie_review_path(#movie) %></span>
<% end %>
<% else %>
<p id="review_message">You will be able to submit a review when the movie releases</p>
<% end %>
Restarted my server and I get the same error.
Been stuck on this for a while and would appreciate any assistance, thanks!
It looks like a bug, I think you want to get reviews not one review:
def show
#reviews = #movie.reviews.order('created_at DESC').paginate(page: params[:page], per_page: 6)
end
View:
<% if #movie.now_playing %>
<% if #reviews.any? %>
<% #reviews.each do |review| %>
<div id="each_review_container">
<span><%= link_to #movie.creator.name, user_path(#movie.creator) %> | </span>
<span id="time"><%= review.created_at.try(:strftime,'%b %d, %Y') %></span>
<p>Rating: <%= review.rating %>/10</p>
<p><%= review.content %></p>
</div>
<% end %>
<div class="digg_pagination"><%= will_paginate #reviews %></div>
<% else %>
<span id="review_message">No Reviews yet!</span>
<span id="add_new_review_link"><%= link_to 'Add New Review', new_movie_review_path(#movie) %></span>
<% end %>
<% else %>
<p id="review_message">You will be able to submit a review when the movie releases</p>
<% end %>
In Your view ,you are calling #movie.reviews
Why are you writing #movie.reviews in loop ?You should be using #review of action instead.It is firing query every time you call it.
#movie.reviews in your view is causing error here's guess,since it doesn't include pagination parameter and you are trying to pagination through it.
I'm trying to create a link that will direct people to the users profile page by clicking on their name when they look at their pics. The line of code is below however, I am not sure how to turn this into a link that will direct people to the users profile. Right now the users post displays their name in association with their post. Hopefully this makes sense Thanks in advance.
<p><strong><%= #post.user.name if #post.user %></strong></p>
The route to the users profile page is users_path.
Post/Show.html
<div class="row">
<div class="col-md-offset-4 col-med-8">
<div class="panel panel-default">
<div class="panel-heading center">
<% if #post.image.url %>
<%= image_tag #post.image.url(:medium) %>
<% elsif #post.video.url %>
<%= video_tag #post.video.url(:medium), controls: true, type: "video/mp4" %>
<% end %>
</div>
<div class="panel-body">
<p><%= #post.description %></p>
<p><strong><%= #post.user.name if #post.user %></strong></p>
<% if #post.user == current_user %>
<%= link_to edit_post_path(#post) do %>
<span class="glyphicon glyphicon-edit"></span>
Edit
<% end %>
<% end %>
<%= link_to 'Back', posts_path %>
</div>
</div>
Considering user_path is path to user's profile
<p>
<strong>
<%= link_to(user.name, user_path(user)) if user = #post.user %>
</strong>
</p>
I did this like this... <%= link_to (#post.user.name), user_path(#post.user) %>
Currently I have a text link within the div that links correctly <%= link_to 'Show', profile %>. I have read that the below is the proper way to turn a div into a link
<%= link_to root_path do %>
<div>Hey!</div>
<% end %>
Though when I apply that to my block it gives me a undefined local variable or method 'profile'
<%= link_to profile do %>
<div id="profiles" class="transitions-enabled">
<% #profiles.each do |profile| %>
<div class="box panel panel-default">
<div class="panel-body">
<%= image_tag profile.image.url(:medium) %>
<%= profile.artist %><br/>
<%= link_to 'Show', profile %>
</div>
</div>
<% end %>
</div>
<% end %>
My original block without the attempt at linking:
<div id="profiles" class="transitions-enabled">
<% #profiles.each do |profile| %>
<div class="box panel panel-default">
<div class="panel-body">
<%= image_tag profile.image.url(:medium) %>
<%= profile.artist %><br/>
<%= link_to 'Show', profile %>
</div>
</div>
<% end %>
</div>
My Controller:
class ProfilesController < ApplicationController
before_action :set_profile, only: [:show, :edit, :update, :destroy, :id]
# GET /profiles
# GET /profiles.json
def index
#profiles = Profile.all
end
# GET /profiles/1
# GET /profiles/1.json
def show
end
# GET /profiles/new
def new
#profile = Profile.new
end
#...
Your first example is problematic in many ways - you have links inside links. I'm not exactly sure what you're looking to output from this - but basically you need the
<%= link_to root_path do %>
<div>Hey!</div>
<% end %>
behavior to replace where you have <%= link_to 'Show', profile %>
Something along the lines of:
<div id="profiles" class="transitions-enabled">
<% #profiles.each do |profile| %>
<div class="box panel panel-default">
<div class="panel-body">
<%= image_tag profile.image.url(:medium) %>
<%= profile.artist %><br/>
<%= link_to profile do %>
<div>
fancy pants stuff here
</div>
<% end %>
</div>
</div>
<% end %>
</div>
If you can give me some guidance on what you want in the div I can post you some code to achieve that, I'm just not clear on what you are looking for exactly.
Another example could be (if you wanted more of the pieces to fall inside that <div></div>:
<div id="profiles" class="transitions-enabled">
<% #profiles.each do |profile| %>
<div class="box panel panel-default">
<div class="panel-body">
<%= link_to profile do %>
<div>
<%= image_tag profile.image.url(:medium) %>
<%= profile.artist %><br/>
... more fancy pants stuff here ...
</div>
<% end %>
</div>
</div>
<% end %>
</div>
