RoR:为什么我的微博不显示?
[英] RoR: why aren't my microposts showing up?
本文介绍了RoR:为什么我的微博不显示?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是用户应该显示的显示视图...
编辑(我稍微更新了这篇文章，你可以在 RoR:我怎样才能让我的微博显示出来?)
<div id="购买"><%=render 'shared/micropost_form_purchase' %>
<div id="销售额"><%=render 'shared/micropost_form_sale' %>
</节><div id="采购清单"><ol class="微博"><%= 渲染@purchases 除非@purchases.nil?％＞</ol>
<div id="销售清单"><ol class="微博"><%= 渲染@sales 除非@sales.nil?％＞</ol>
所以表格(部分)加载得很好，但是当我发帖时，在任何一个中，采购清单和销售清单都没有出现.我检查了数据库，它们正在与列中的条目一起创建，指示种类(销售或购买)
表格如下:
<%= form_for (@micropost) do |f|％＞<div class="字段无缩进"><%= f.text_area :content, placeholder: 你还有什么想买的?"％＞<%= hidden_field_tag 'micropost[kind]', "购买" %>
<%= f.submit "Post", class: "btn btn-large btn-primary" %><%结束%>
和
<%= form_for (@micropost) do |f|％＞<div class="字段无缩进"><%= f.text_area :content, placeholder: 你还有什么想买的?"％＞<%= hidden_field_tag 'micropost[kind]', "sale" %>
<%= f.submit "Post", class: "btn btn-large btn-primary" %><%结束%>
此外，这里是 users_controller.rb 的显示部分
def show@user = User.find(params[:id])@micropost=Micropost.new@microposts = @user.microposts.paginate(page: params[:page])结尾
这里是 microposts_controller.rb 的展示部分
def 显示@micropost = Micropost.find(params[:id])@microposts = Micropost.where(:user_id => @user.id)@purchases = @microposts.where(:kind => "purchase")@sales = @microposts.where(:kind => "sale")结尾
谁能帮帮我?我还需要什么吗?嗯
解决方案
首先，为了确保获得想要的结果，您应该在视图中尝试这样的操作
<%= @sales %>
这应该是您想要的结果的散列.然后，如果这看起来不错，你想做这样的事情
<ol class="微博"><% 如果@sales.any?％＞<% @sales.each 做 |sale|％＞<li><%=销售额%></li><%结束%><%结束%></ol>
重复购买
Here is the users show view where they are supposed to show up. ..
edit (I have updated this post slightly you can see it at RoR: How can I get my microposts to show up?)
<section>
<div id= "purchases">
<%= render 'shared/micropost_form_purchase' %>
</div>
<div id="sales">
<%= render 'shared/micropost_form_sale' %>
</div>
</section>
<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>
so the forms (partials) are loading fine, but then when I make a post, in either one, neither the purchases list nor the sales list shows up. I checked the database and they are being created along with an entry in the column indicating kind (either sale or purchase)
Here are the forms:
<%= form_for (@micropost) do |f| %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= hidden_field_tag 'micropost[kind]', "purchase" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
and
<%= form_for (@micropost) do |f| %>
<div class="field no-indent">
<%= f.text_area :content, placeholder: "What's something else you want to buy?" %>
<%= hidden_field_tag 'micropost[kind]', "sale" %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
also, here is the show part of the users_controller.rb
def show
@user = User.find(params[:id])
@micropost=Micropost.new
@microposts = @user.microposts.paginate(page: params[:page])
end
and here is the show part of the microposts_controller.rb
def show
@micropost = Micropost.find(params[:id])
@microposts = Micropost.where(:user_id => @user.id)
@purchases = @microposts.where(:kind => "purchase")
@sales = @microposts.where(:kind => "sale")
end
can anyone help me out? anything else i need? hmmm
解决方案
First, just to be sure you are getting the results you want, you should try something like this in your view
<%= @sales %>
This should be a hash of the results you want. Then, if that looks good, you want to do something like this
<div id="sales_list">
<ol class="microposts">
<% if @sales.any? %>
<% @sales.each do |sale| %>
<li><%= sale %></li>
<% end %>
<% end %>
</ol>
</div>
And repeat for purchases
