我希望它们显示在主页上。我想我可能遇到麻烦,因为有一个belongs_to has_many关系。每个微博属于用户,每个用户都有很多微博。我让它们显示在用户页面上(但这只是用户微博的列表,而不是每个人都是我想要的主页)。如果从视图中不清楚。我想要两个单独的列表。一个包含所有类型“购买”的所有微博的列表和所有“销售”微博的另一个列表。 Kind是微博数据库中的一列。现在没有任何显示,也没有错误...
这是app / views / static_pages / home.html.erb
<div id="purchases list">
<ol class="microposts">
<%= render @purchases unless @purchases.nil? %>
</ol>
</div>
<div id="sales list">
<ol class="microposts">
<%= render @sales unless @sales.nil? %>
</ol>
</div>
这是app / views / microposts / _micropost.html.erb(我不确定这是否重要)
<li>
<span class="content"><%= micropost.content %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(micropost.created_at) %> ago.
</span>
<% if current_user?(micropost.user) %>
<%= link_to "delete", micropost, method: :delete,
confirm: "You sure?",
title: micropost.content %>
<% end %>
</li>
在模型文件(micropost.rb)中对微博的定义中使用范围可能很重要
scope :purchases, where(:kind => "purchase")
scope :sales, where(:kind => "sale")
这是microposts_controller.rb
class MicropostsController < ApplicationController
before_filter :signed_in_user
before_filter :correct_user, only: :destroy
def home
@microposts=Micropost.all
@purchases=@microposts.collect{ |m| m if m.kind == "purchase"}.compact
@sales=@microposts.collect{ |m| m if m.kind == "sale"}.compact
def show
@micropost = Micropost.find(params[:id])
@microposts = @user.microposts
@purchases= @microposts.purchases
@sales = @microposts.sales
end
,这是users_controller.rb
class UsersController < ApplicationController
before_filter :signed_in_user,
only: [:index, :edit, :update, :destroy, :following, :followers]
before_filter :correct_user, only: [:edit, :update]
before_filter :admin_user, only: :destroy
def index
@users = User.paginate(page: params[:page])
end
def show
@user = User.find(params[:id])
@micropost=Micropost.new
@microposts = @user.microposts
@purchases= @microposts.purchases
@sales = @microposts.sales
end
def home
@microposts = Micropost.all
@purchases = @microposts.collect{ |m| m if m.kind == "purchase"}.compact
@sales = @microposts.collect{ |m| m if m.kind == "sale"}.compact
end
答案 0 :(得分:1)
您的XController
会在app/views/X
中查找视图模板,因此您需要将home.html.erb
移出app/views/static_pages
并转移到app/views/users
或app/views/microposts
。另外,为什么两个控制器中都有相同的home
方法?
如果这对您不起作用,我想知道(a)您要浏览的网址,以及(b)routes.rb
文件中的内容。
