How to add comments to statuses (like facebook) - ruby-on-rails

Question

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

Answer 1

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
