Rails 4 resource customization issues - ruby-on-rails

We have a tags resource:
resources :tags, only: [:index, :show, :update, :destroy]
And I'm trying to copy the functionality of the tags/tag partial:
<%= render partial: 'tags/tag', collection: tags %> ## <~ my copy ##
<%= render partial: 'collections/collection', collection: collections %>
<%= render partial: 'saved_searches/saved_search', collection: saved_searches %>
<%= render partial: 'tags/tag', collection: tags %>
<%= render feeds %>
Here is the _tag.html.erb partial:
<% hide_drawer = (session[:view_mode] == 'view_unread' && tag.unread_count == 0 && !tag.user_feeds.any?) ? true : false %>
<li data-tag-id="<%= tag.id %>" data-feed-id="tag-<%= tag.id %>" class="<%= selected("tag_#{tag.id}") %>">
<%= link_to tag_path(tag.id), remote: true, class: 'feed-link tag-link', data: { behavior: 'selectable reset_entry_position show_entries open_item feed_link', mark_read: {type: 'tag', data: tag.id, message: "Mark #{tag.name} as read?"}.to_json } do %>
<span class="favicon-wrap">
<span class="favicon favicon-tag"></span>
</span>
<%= content_tag :span, tag.unread_count, class: 'count' + hide_count(tag.unread_count) %>
<% unless hide_drawer %>
<%= render partial: 'tags/tag_visibility', locals: {user: #user, tag: tag} %>
<% end %>
<%= tag.name %>
<% end %>
<div class="drawer <%= hide_drawer ? ' hide' : '' %>" data-hidden="<%= drawer_visible?(tag.id) ? 'false' : 'true' %>" style="<%= drawer_visible?(tag.id) ? '' : 'height: 0;' %>">
<ul>
<%= render tag.user_feeds %>
</ul>
<i class="drawer-arrow"></i>
</div>
</li>
And here is the show method:
def show
#user = current_user
update_selected_feed!("tag", params[:id])
#tag = Tag.find(params[:id])
#feed_ids = Tagging.where(tag_id: #tag, user_id: #user).pluck(:feed_id)
feeds_response
#append = !params[:page].nil?
#type = 'tag'
#data = params[:id]
#collection_title = #tag.name
#collection_favicon = 'favicon-tag'
respond_to do |format|
format.js { render partial: 'shared/entries' }
end
end
What I'm trying to do is reuse the same partial and only output the tag named "Mailbox". Would I need to add some logic to the method to have the partial show only the tag named "Mailbox"? How would I tell the partial to display only a single "Mailbox" tag? Any suggestions or help would be appreciated I'm a new Rails developer.

Two ways.
Pass local
<%= render partial: 'tags/tag', locals: {tag: tags.find{|t| t.name == "Mailbox"}}%>
Pass an array with just just one tag
<%= render partial: 'tags/tag', collection: tags.collect{|t| t.name == "Mailbox"} %>

Rails 7 turbo-stream broadcast to specific channel not working

I have a Post model and Comment, and Post has_many Comment and I wanna real-timely update the comment when you are in a specific post, meaning, the comments live-updating should only visible when multiple users are in the same post, for example: in posts/6
For View I have:
<div>
<p>
<strong>Title:</strong>
<%= post.title %>
</p>
<p>
<strong>Content:</strong>
<%= post.content %>
</p>
<p>
<strong>User:</strong>
<%= post.user.username %>
</p>
</div>
<hr/>
<%= form_for [post, Comment.new] do |f| %>
Body: <%= f.text_area :body, rows: 5, cols: 20 %>
<%= f.submit "Submit" %>
<% end %>
<hr/>
<h1>Comments:</h1>
<%= turbo_stream_from post %>
<%= turbo_frame_tag post do %>
<div id="<%= dom_id(post) %>">
<% post.comments.includes(:user).each do |comment| %>
<%= render comment %>
<% end %>
</div>
<% end %>
In Comment#create action I have:
post = Post.find(params[:post_id])
#comment = post.comments.new(comment_params)
#comment.user_id = current_user.id
respond_to do |format|
if #comment.save
format.turbo_stream { render turbo_stream: turbo_stream.prepend("post_#{post.id}", partial: "comments/comment", locals: { comment: #comment }) }
else
format.html { render :new, status: :unprocessable_entity }
format.json { render json: #comment.errors, status: :unprocessable_entity }
end
end
In Comment model I have:
after_create_commit {
broadcast_prepend_to(target: "post_#{self.post.id}")
}
And in terminal I can see
[ActionCable] Broadcasting to : "<turbo-stream action=\"prepend\" target=\"post_6\"><template> <div>\n <p>\n <strong>Title:</strong>\n adsd\n </p>\n\n <p>\n <strong>Content:</strong>\n Asda\n </p>\n\n <p>\n <strong>User:</strong>\n Super Saiyan Vegeta\n </p>\n </div>\n\n <hr/>\...
Which is correct, but the comments list in a specific post still not updating, and I do see I have id="post_6" in the view...can someone tell me why? Thanks.
Try to change
<div id="<%= dom_id(post) %>">
to
<div id="post_<%= post.id %>">
And use such method in controller
if #comment.save
#comment.broadcast_prepend_to to post, target: "post_#{post.id}", partial: "comments/comment", locals: { comment: #comment }
end
instead of broadcast from model

AJAX not working in Rails same-page update

I am trying to build a Q&A app with Ajax on the Index.html.erb. I manage to get the form remotely loading, but when saving the records, the AJAX does not work and the user is taken to the normal show.html.erb. Apart from the Ajax not kicking off, everything works well.
My code is as below:
index.html.erb (Contain a partial for input, and a partial for results)
<div>
<h3 class="section_title"> Q&A </h3>
<hr>
<div id="qanda-form" style="display:none;"> </div>
</div>
<div id="qandas">
<%= render 'qandas/qanda' %>
</div>
_qanda.html.erb (is the partial for results)
<% #qandas.each do |my_qanda| %>
<div class="col-md-9">
<div>
Created <%= local_time(my_qanda.created_at) %>, by <%= User.find_by(id: my_qanda.user_id).full_name %>
</div>
</div>
<% end %>
_form.html.erb (is the input form - has nested form via Cocoon)
<%= simple_form_for #qanda, remote: true do |f| %>
<%= f.error_notification %>
<%= f.error_notification message: f.object.errors[:base].to_sentence if f.object.errors[:base].present? %>
<div class="col-md-12 form-inputs">
<div class="col-md-8">
<%= f.input :title, label: 'Q&A Title:' %>
</div>
</div>
<div class="qandasquestions">
<%= f.simple_fields_for :qandasquestions do |builder| %>
<% render 'qandas/qandasquestion_fields', f: builder %>
<% end %>
<div class="links btn-group" style="min-height: 34px !important">
<%= f.button :submit, "Publish Q&A", class: "btn btn-default" %>
<%= link_to_add_association 'Add Question', f, :qandasquestions, class: 'btn btn-default', data: {association_insertion_node: '.qandasquestions', association_insertion_method: :append} %>
<%= link_to 'Back', qandas_path, class: "btn btn-default" %>
<%= f.input :company, :as => :hidden, :input_html => {:value => current_user.company} %>
</div>
</div>
<% end %>
Controller:
def index
#qandas = Qanda.all
respond_to do |format|
#qandas = Qanda.all
format.html
format.json
end
end
def create
#qanda = current_user.qandas.build(qanda_params)
respond_to do |format|
if #qanda.save!
#qandas = Qanda.all
format.html { redirect_to #qanda, notice: 'Qanda was successfully created.' }
format.json {render :layout => false}
else
format.html { render :new }
format.json { render json: #qanda.errors, status: :unprocessable_entity }
end
end
end
create.js.erb
$('#qandas').html("<%= j render partial: 'qandas/qanda' %>");
$('#qanda-form').slideUp(350);
new.js.erb
$('#qanda-form').html("<%= j render 'qandas/form' %>");
$('#qanda-form').slideDown(350);
Anybody can see why the Ajax does not kick off please? why am I redirected to the traditional SHOW page please?
Try updating your code to this and let me know if it's working?
def create
#qanda = current_user.qandas.build(qanda_params)
if #qanda.save!
#qandas = Qanda.all
else
#errors = #qanda.errors
end
end

ajax like/unlike post in rails 4

Ive been working to implement a like/unlike feature which works with ajax. I have already built and tested the models and associations which seem to working fine. What I am having problems with is rendering the actual like/unlike button in the view. I have been using this https://github.com/Aufree/ting/tree/master/app/controllers github projects like/unlike system as reference for building my own.
Heres my controller likeships_controller.rb
before_action :authenticate_user!
include LikeshipsHelper
def create
current_user.like!(params[:likeable_type], params[:likeable_id])
respond_to do |format|
format.html { redirect_to correct_path }
format.js
end
end
def destroy
current_user.unlike!(params[:likeable_type], params[:likeable_id])
respond_to do |format|
format.html { redirect_to correct_path }
format.js
end
end
Heres my likeship_helper.rb
module LikeshipsHelper
def likeable_likes_tag like
#count = Likeship.where("likeable_type = ? and likeable_id = ?", like[:likeable_type], like[:likeable_id]).count
if #count > 0
likes_count = #count
else
likes_count = ''
end
if current_user && current_user.liking?(like)
link_title = "unlike"
link_path_method = "delete"
fa_icon = '<i class="red heart icon"></i>'
else
link_title = "like"
link_path_method = "post"
fa_icon = '<i class="red heart empty icon"></i>'
end
if current_user.blank?
"#{likes_count}#{fa_icon}".html_safe
else
link_to "#{likes_count}#{fa_icon}".html_safe,
likeships_path(like),
title: link_title,
class: "animated zoomIn",
method: link_path_method,
remote: true
end
end
def correct_path
if params[:likeable_type].to_s == "Post"
post_path(params[:likeable_id])
end
end
end
these are my views
_like.html.erb
<i class="red heart icon">
<%= form_for(current_user.likeships.build) do |f| %>
<%= f.hidden_field :likeable_type, value: #likeable[:likeable_type] %>
<%= f.hidden_field :likeable_id, value: #likeable[:likeable_id] %>
<%= f.submit %>
<% end %>
</i>
_likes.html.erb
<% if user_signed_in? %>
<% if current_user.liking?(#likeable) %>
<%= render 'likeships/unlike' %>
<% else %>
<%= render 'likeships/like' %>
<% end %>
<% end %>
EDIT: Now if i use this in the _post.html.erb view no error is thrown but no like/unlike button appears either.
<div class="post_wrapper">
<div class="media_wrapper">
<span class="name"><%= link_to post.user.name, post.user, class: "name" %></span>
<p class="media"><%= post.body_html %></p>
<div class="date_and_like">
<span class="item" id="like-post-#{#post.id}" >
<% #likeable = Likeship.likeable(#post) %>
<%= likeable_likes_tag #likeable %>
</span>
<span class="timestamp"><%= time_ago_in_words(post.created_at) %> ago </span>
</div>
</div>
heres the create.js.erb file
$("#like-post-<%= params[:likeable_id] %>").html("<%= j(likeable_likes_tag #likeable) %>")
So I also tried to render the likes form in the post view with this
but it gave me an error that
undefined method `[]' for nil:NilClass
Ive been stumped for hours trying to figure this out any help would be awesome, also let me know if you need any additional info, Thanks.

How to use partials with more than one collection in rails

I want to use two collection #ad_item and #user in my partial. Here is my index erb...
<% if #ad_items.any? && #user.any? %>
<%= render partial: 'yourads/ad_item', collection: {#ad_items,#user} %>
<% end %>
and here is my controller ...
def index
#ad_items = Yourad.all
#user = User.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: #yourads }
end
end
and here is my _ad_item.erb.html partial
<span class="date"><%= ad_item.created_at.to_date() %></span>
<span class="location"><%= ad_item.title %></span>
<div style="float:left"><%= ad_pic #user,ad_item %></div>
<div class="description"><%= ad_item.description %></div>
My helper function is ..
def ad_pic(user,ad)
cl_image_tag("Ad#{user.id}#{ad.id}.jpg", :version => rand(1000000000), :alt => "Ad pic",:width => 70, :height => 70, :crop => :fill)
end
it gives syntax error in ..
<%= render partial: 'yourads/ad_item', collection: {#ad_items,#user} %>
<%= render partial: 'yourads/ad_item', collection: #ad_items ,
locals: {users: #users} %>
and in view
<% for user in users %>
<span class="date"><%= ad_item.created_at.to_date() %></span>
<span class="location"><%= ad_item.title %></span>
<div style="float:left"><%= ad_pic user,ad_item %></div>
<div class="description"><%= ad_item.description %></div>
<% end %>
see Passing Local Variables
<%= render partial: 'yourads/ad_item', :locals => {:ad_items=>#ad_items,:user => #user }%>
you can access #ad_items as ad_items and #user as user in your yourads/ad_item partial

After submit form I want to stay in the same page and display :notice messages

All my code is working nicely, I want to render the same page :new after a user submits a form with your order. The problem is about the :notice message that I want to display Pedido enviado com sucesso. in the page after a submission but it doesn't work. My validation error messages are displayed nicely but I don't know why my success message doesn't.
Any tips?
(Sorry about my code indentation)
My pedidos_controller goes down:

def new
#pedido = Pedido.new
1.times do
pessoa = #pedido.build_pessoa
produto = #pedido.produtos.build
end
respond_to do |format|
format.html # new.html.erb
format.json { render json: #pedido }
end
end
def create
#pedido = Pedido.new(params[:pedido])
respond_to do |format|
if #pedido.save
PedidosMailer.delay.registro_do_pedido(#pedido)
PedidosMailer.delay.email_para_cotar_produtos(#pedido)
format.html { redirect_to action: "new", notice: 'Pedido enviado com sucesso.' }
format.json { render json: #pedido, status: :created, location: #pedido }
else
format.html { render action: "new" }
format.json { render json: #pedido.errors, status: :unprocessable_entity }
end
end
end
end
my new.html.erb view:

You need to use flash[:notice], not notice, in your view:
<% if flash[:notice] %>
<p id="notice"><%= flash[:notice] %></p>
<% end %>
When you pass a message via the notice: parameter of redirect_to, it's placed into the flash array, which is a special pseduo-session which persist for a single request:
From the ActionController::Redirecting documentation:
It is also possible to assign a flash message as part of the redirection. There are two special accessors for the commonly used flash names alert and notice as well as a general purpose flash bucket.
