MVC4制作网站教程第二章 用户修改资料2.4

一、用户 
1.1用户注册 
1.2用户登录 
1.3修改密码 
1.4修改资料 

在用户登陆成功后要跳转到一个页面，暂且叫做用户中心吧。在【usercontroller】添加[default] action 

[userauthorize]
 public actionresult default()
 {
  userrsy = new userrepository();
  var _user = userrsy.find(username);
  return view(_user);
 } 

添加相应对应强类型视图 

@model ninesky.models.user
@{
 viewbag.title = "首页";
 layout = "~/views/layout/_user.cshtml";
}

<div class="leftnav">这里左侧导航列表</div>
<div class="workspace">
 <div class ="nav">您现在的位置： 用户首页</div>
 <div>@model.username
 <br />
 @model.groupid
 </div>
</div> 

现在要把左侧导航列表做出来，在视图的user文件夹上点右键新建局部视图partialpersonalnav

<ul>
 <li>@html.actionlink("用户首页","default","user")</li>
 <li>@html.actionlink("修改信息","changeinfo","user")</li>
 <li>@html.actionlink("修改密码","changepassword","user")</li>
 <li>@html.actionlink("退出系统","logout","user")</li>
</ul> 

将default.cshtml中“这里左侧导航列表”替换为@html.partial("partialpersonalnav")。浏览器中打开，导航列表显示出来了。 

现在开始做修改用户资料了。在【usercontroller】添加[changeinfo] action 

[userauthorize]
 public actionresult changeinfo()
 {
  userrsy = new userrepository();
  var _user = userrsy.find(username);
  return view(_user);
 } 

 

添加修改资料的处理 action

[httppost]
 [userauthorize]
 public actionresult changeinfo(user user)
 {
  userrsy = new userrepository();
  if(userrsy.authentication(username,ninesky.common.text.sha256(user.password))==0)
  {
  var _user = userrsy.find(username);
  _user.gender = user.gender;
  _user.email = user.email;
  _user.qq = user.qq;
  _user.tel = user.tel;
  _user.address = user.address;
  _user.postcode = user.postcode;
  if (userrsy.update(_user))
  {
   notice _n = new notice { title = "修改资料成功", details = "您已经成功修改资料！", dwelltime = 5, navigationname = "用户首页", navigationurl = url.action("default", "user") };
   return redirecttoaction("usernotice", "prompt", _n);
  }
  else
  {
   error _e = new error { title = "修改资料失败", details = "在修改用户资料时时，更新的资料未能保存到数据库", cause = "系统错误", solution = server.urlencode("<li>返回<a href='" + url.action("changeinfo", "user") + "'>修改资料</a>页面，输入正确的信息后重新操作</li><li>联系网站管理员</li>") };
   return redirecttoaction("usererror", "prompt", _e);
  }
  }
  else
  {
  modelstate.addmodelerror("password","密码错误！");
  return view();
  }
  
  
 } 

aciton上右键添加强类型视图，修改视图里自动生成代码，完成后。如下： 

@model ninesky.models.user

@{
 viewbag.title = "修改个人资料";
 layout = "~/views/layout/_user.cshtml";
}

<div class="leftnav">@html.partial("partialpersonalnav")</div>
<div class="workspace">
 <div class="nav">您现在的位置： 用户首页</div>
 <div>
 @using (html.beginform())
 {
  @html.validationsummary(true)

  <fieldset>
  <legend>修改资料</legend>
  @html.hiddenfor(model => model.userid)
  <ul>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.username)
   </div>
   <div class="editor-field">
    @html.displayfor(model => model.username)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.password)
   </div>
   <div class="editor-field">
    @html.password("password")
    @html.validationmessagefor(model => model.password)
    输入正确的密码才能修改资料。
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.gender)
   </div>
   <div class="editor-field">
    @html.radiobuttonfor(model => model.gender, 0) 男
   @html.radiobuttonfor(model => model.gender, 1) 女
   @html.radiobuttonfor(model => model.gender, 2) 保密
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.email)
   </div>
   <div class="editor-field">
    @html.editorfor(model => model.email)
    @html.validationmessagefor(model => model.email)
    @html.displaydescriptionfor(model => model.email)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.qq)
   </div>
   <div class="editor-field">
    @html.editorfor(model => model.qq)
    @html.validationmessagefor(model => model.qq)
    @html.displaydescriptionfor(model => model.qq)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.tel)
   </div>
   <div class="editor-field">
    @html.editorfor(model => model.tel)
    @html.validationmessagefor(model => model.tel)
    @html.displaydescriptionfor(model => model.tel)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.address)
   </div>
   <div class="editor-field">
    @html.editorfor(model => model.address)
    @html.validationmessagefor(model => model.address)
    @html.displaydescriptionfor(model => model.address)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @html.labelfor(model => model.postcode)
   </div>
   <div class="editor-field">
    @html.editorfor(model => model.postcode)
    @html.validationmessagefor(model => model.postcode)
    @html.displaydescriptionfor(model => model.postcode)
   </div>
   </li>
   <li><input type="submit" value="修改" /></li>
  </ul>
  </fieldset>
 }
 </div>
</div>

@section scripts {
 @scripts.render("~/bundles/jqueryval")
} 

运行一下看

 

输入资料测试一下。能够正常保存到数据库。 

====================================== 
刚开始学mvc，加之表达能力有限，也没有事先写个大致计划，写的很差、很乱。现在是想到哪里就写哪里，有时候做到后面了，发现前边写的不行又去改前面写的代码。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
