<%= button_tag(type: 'submit',class: "btn")  do %>
  ...
<%= button_tag(type: 'submit',class: "btn",id: "2",name: 'private')  do %>

我们将下面的内容放在控制器中,但由于私有按钮将包含许多不同的_forms,我是否必须将它放在每个控制器中,还是可以将它放在应用程序控制器中？

if params[:private]
  # the private action / What do we need to put here?
else
  # normal submit / and here?

我跟着这个铁路播放节目几乎到了T来建立活动饲料：http://railscasts.com/episodes/406-public-activity.

以下是公开个人资料的代码：

users_controller.rb

def show
   @user = User.find(params[:id])
   @habits = @user.habits
   @valuations = @user.valuations
   @accomplished_goals = @user.goals.accomplished
   @unaccomplished_goals = @user.goals.unaccomplished
   @averaged_quantifieds = @user.quantifieds.averaged
   @instance_quantifieds = @user.quantifieds.instance
end

show.html.erb

<% if @user.habits.any? %>
  <h2>Habits</h2>
  <h4>Challenges</h4>
  <%= render partial: 'habits',locals: {habits: @habits} %>
<% end %>

<% if @user.valuations.any? %>
  <h2>Values</h2>
  <%= render @valuations %>
<% end %>

<% if @user.goals.any? %>
  <h2>Goals</h2>
  <h4> Current</h4>
  <%= render @unaccomplished_goals %>
<% end %>

<% if @user.goals.any? %>
  <h4>Accomplished</h4>
  <%= render @accomplished_goals %>
<% end %>

<% if @user.quantifieds.any? %>
  <h2>Stats</h2>
  <h4>Averaged</h4>
  <%= render partial: 'averaged',locals: {habits: @averaged_quantifieds} %>
<% end %>

<% if @user.quantifieds.any? %>
  <h4>Instance</h4>
  <%= render partial: 'instance',locals: {habits: @instance_quantifieds} %>
<% end %>

UPDATE

有了K的答案,我会在转到用户或用户/ 1,用户/ 2等时收到此错误消息.
