В моем приложении rails я использую драгоценный камень, социализацию. Я просто не могу понять, как отображать количество понравившихся!Rails - Получить количество понравившихся сообщений
Мой пост Контроллер:
class PostsController < ApplicationController
# GET /posts
# GET /posts.json
def index
@posts = Post.all(:order => "created_at DESC")
@posts_not_signed_in = Post.all(:order => "created_at DESC")
@post = Post.new
@users = User.all(:order => "created_at DESC")
respond_to do |format|
format.html # index.html.erb
format.json { render json: @posts }
end
end
def like
post.liked_by current_user
redirect_to root_path
end
# GET /posts/1
# GET /posts/1.json
def show
redirect_to posts_path
end
# GET /posts/new
# GET /posts/new.json
def new
@post = Post.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @post }
end
end
# GET /posts/1/edit
def edit
@post = Post.find(params[:id])
end
# POST /posts
# POST /posts.json
def create
@post = current_user.posts.build(params[:post])
respond_to do |format|
if @post.save
format.html { redirect_to @post, notice: 'Post was successfully created.' }
format.json { render json: @post, status: :created, location: @post }
else
format.html { render action: "new" }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# PUT /posts/1
# PUT /posts/1.json
def update
@post = Post.find(params[:id])
respond_to do |format|
if @post.update_attributes(params[:post])
format.html { redirect_to @post, notice: 'Post was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.json
def destroy
@post = Post.find(params[:id])
@post.destroy
respond_to do |format|
format.html { redirect_to posts_url }
format.json { head :no_content }
end
end
end
Мой контроллер пользователя:
class UsersController < ApplicationController
def index
@users = User.all
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @users }
end
end
def show
@user = User.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @user }
end
end
def follow
@user = User.find(params[:id])
current_user.toggle_follow!(params[:id])
redirect_to root_path
end
def unfollow
@user = User.find(params[:id])
current_user.stop_following(@user)
redirect_to root_path
end
end
Мой пост Модель:
class Post < ActiveRecord::Base
attr_accessible :status, :author, :username, :id, :user_id, :user, :website, :bio, :skype, :dob, :age, :email, :motto, :follower, :followable, :votes
belongs_to :user
has_many :like
has_many :likes
validates :status, :presence => true
acts_as_likeable
acts_as_votable
end
Моя модель пользователя:
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me, :username, :user_id, :id, :website, :bio, :skype, :dob, :age, :motto, :follower, :followable
has_many :posts
acts_as_liker
# attr_accessible :title, :body
end
Мое мнение:
<% if user_signed_in? %>
<h1 id="welcome" class="nuvo">Welcome <%= current_user.username %>!</h1>
<% else %>
<h1 id="welcome" class="nuvo">Log-In to make some posts!</h1>
<% end%>
<div class="follow-row">
<div class="titan-users nuvo"><h2>BoomIt Users</h2></div>
<div class="user-row nuvo"><%= link_to 'coreypizzle', user_path(1) %> - <%= link_to 'BoomBoard', dashboard_path(1) %></div>
<% @users.each do |user| %>
<div class="user-row nuvo"><%= link_to user.username, user_path(user.id) %> - <%= link_to 'BoomBoard', dashboard_path(user.id) %></div>
<% end %>
</div>
<div class="statuses">
<% if user_signed_in? %><div class="status-form"><%= render 'form' %></div><% end %>
<% if user_signed_in? %>
<% @posts.each do |post| %>
<div class="post">
<div class="tstamp">
<%= image_tag avatar_url_small(post.user), :class => 'gravatar' %>
<strong>Posted <%= time_ago_in_words(post.created_at) %> ago by <%= post.user.username %></strong>
</div>
<div class="status"><%= post.status %></div>
<div class="likearea"><%= link_to 'BoomThis', 'posts/like', :class => 'wtxt nuvo' %> - <%= @post.likes.size %></div>
</div>
<% end %>
<% else %>
<% @posts_not_signed_in.each do |post| %>
<div class="post">
<div class="tstamp">
<%= image_tag avatar_url_small(post.user), :class => 'gravatar' %>
<strong>Posted <%= time_ago_in_words(post.created_at) %> ago by <%= post.user.username %></strong>
</div>
<div class="status"><%= post.status %></div>
</div>
<% end %>
<% end %>
</div>
Любая помощь будет принята с благодарностью!
Спасибо, CoreyPizzle
nope, что просто говорит «undefined method likes» – coreypizzle
Вы удалили has_many: нравится, что ломает рельсы грамматики, у вас должно быть только has_many: нравится – rovermicrover
Вы имеете в виду подписи для одного сообщения или все сообщения? – rovermicrover
