在我的 Rails 应用程序中,我需要在该用户所做的用户“仪表板”帖子上显示。
仪表板控制器:
class DashboardController < ApplicationController
def index
@users = User.all
@user = User.find(params[:id])||current_user
respond_to do |format|
format.html # index.html.erb
format.json { render json: @posts }
end
end
def show
@user = User.find(params[:id])
@post = Post.all(:order => "created_at DESC")
respond_to do |format|
format.html # show.html.erb
format.xml { render :xml => @user }
end
end
end
我的仪表板“显示视图”
<div class="dash-well">
<div class="gravatar-dashboard">
<%= image_tag avatar_url(@user), :class => 'gravatar-pos-fix gr-dash-mar-top' %>
<h1 class="nuvo wtxt"><%= @user.username.capitalize %></h1>
<h3 class="nuvo wtxt"><%= @user.motto %></h3>
</div>
</div>
<div class="dash-well-status">
<% @post.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 %>
</div>
和我的仪表板模型:
class Dashboard < ActiveRecord::Base
attr_accessible :status, :author, :email, :username, :id, :user_id, :user, :website, :bio, :skype, :dob, :age
has_many :posts
belongs_to :user
end
那么,有谁知道我如何只显示用户仪表板中的帖子(用户仪表板可以从任何用户访问,所以 current_user 不会工作!)
