控制檯顯示確定但瀏覽器顯示錯誤？

Question

嗨朋友，我帶來了一個新問題。在我的Rails應用程序中，我有一個任務控制器和模型。當我嘗試創建一個新任務時，我得到錯誤消息「due_date」不應該爲空，但是當我檢查我的控制檯時，有一個成功消息。這裏是我的代碼：

我的控制器：

class TasksController < ApplicationController 

    layout "payroll" , :except => [:closed,:today,:this_week, :this_month] 

    # GET /tasks 
    # GET /tasks.xml 
    def index 
    @menu = "Timesheet" 
    @page_name = "Manage Task" 
    company_id = Company.find_by_subdomain(request.subdomain) 
    @users = User.find_all_by_company_id(company_id) 
    @tasks = Task.find_all_by_assigned_to(session[:current_user_id].to_i)#.page(params[:page]) 
    @task = Task.new 

    respond_to do |format| 
     format.html # index.html.erb 
     format.html # new.html.erb 
     format.xml { render :xml => @tasks } 
    end 
    end 
# POST /tasks 
    # POST /tasks.xml 
    def create 
    @task = Task.new(params[:task]) 
    #@task.assigned_to = session[:user_id] 
    @task.task_status = "0" 

    respond_to do |format| 
     if @task.save 
     Email.task_created(@task).deliver 
     @tasks = Task.all 
     @task = Task.new 
     format.html { redirect_to tasks_path } 
     format.xml { render :xml => @task, :status => :created, :location => @task } 
     else 
     format.html { render :action => "new" } 
     format.xml { render :xml => @task.errors, :status => :unprocessable_entity } 
     end 
    end 
    end 

我的模型：

class Task < ActiveRecord::Base 
    #validation start 
    validates :description, :due_date, :assigned_to, :priority, :presence => true 
    validates_length_of :description, :maximum =>500 
end 

和查看：

<%= form_for(@task) do |f| %> 
    <%= render 'shared/form_error', :object => @task %> 

    <div class="field"> 
     <%= f.label :description %><br /> 
     <%= f.text_area :description ,:rows => "2", :cols => "20" %> 
    </div> 
    <div class="field"> 
     <%= f.label :due_date %><br /> 
     <%= f.text_field :due_date %> 
    </div> 
    <div class="field"> 
     <%= f.label :assigned_to %><br /> 
     <%= collection_select(:task, :assigned_to, User.all, :id, :first_name, :prompt =>true) %> 
    </div> 
    <div class="field"> 
     <%= f.label :priority %><br /> 
     <%= f.select (:priority, [['High'],['Medium'],['Low']]) %> 
    </div> 

    <div class="actions"> 
     <button type="submit" class="btn"><img src="/images/add.png" />&nbsp; Add This Task</button> 
    </div> 
<% end % 

我的控制檯消息：

這裏我用擔憂的壓延display.But原因Ĵ查詢日期選擇器，爲什麼我的任務沒有保存？請指導我。提前致謝。

HI朋友我帶了一個答案，我只是在我的公共文件夾中添加了幾個css和java腳本文件，問題就解決了。

Answer 2

你在你的代碼

format.xml { render :xml => @task, :status => :created, :location => @task }

後調用保存的@task = Task.new assignement後有一個錯誤。

此錯誤可能是由於發佈的due_date的格式無效。正如@jimworm請求的那樣，提供POST請求，而不是索引頁面請求。從這個請求我們可以得到提交的參數，你可以嘗試在rails c從提交的字符串創建Date並檢查它是否不是nil。
