你好我正在做简单的更新..
登录的_customer_controller.rb
class LoggedCustomerController < ApplicationController
before_filter :authorize
helper_method :current_customer
layout "frontend"
def current_customer
@current_customer ||= Customer.find(session[:customer_id]) if session[:customer_id]
end
def authorize
if session[:auth] != true
redirect_to login_path, :notice => "Not logged."
end
end
def show
end
def edit
end
def update
respond_to do |format|
if current_customer.update_attributes(params[:current_customer])
format.html { redirect_to view_path, notice: 'Customer was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: current_customer.errors, status: :unprocessable_entity }
end
end
end
end
路线.rb
match "view" => "logged_customer#show", :via => :get
match "edit" => "logged_customer#edit", :via => :get
match "edit" => "logged_customer#edit", :via => :put
编辑.html.erb
<%= form_for current_customer, :url => url_for(:controller => 'logged_customer', :action => 'edit'), :html => { :class => 'form-horizontal' } do |f| %>
<% if current_customer.errors.any? %>
<div id="error_explanation">
<div class="alert alert-error">
The form contains <%= pluralize(current_customer.errors.count, "error") %>.
</div>
<ul>
<% current_customer.errors.full_messages.each do |msg| %>
<li> <%= msg %></li>
<% end %>
</ul>
</div>
<% end %>

我可以显示 localhost:3000/view 编辑按钮在哪里。在 localhost:3000/edit 表单显示有自动填充的信息,一切看起来都很好。当我单击提交按钮时,我重定向到相同的编辑自动填充表单但没有任何错误?所以我猜有一些错误,因为更新失败和另一个错误,它不呈现错误。我做错了什么?
我已经记录了_customer_controller.rb,因为customer_controller.rb 用于管理目的并且已获得授权。
在 Development.log 我只有(看起来不错)
