首先感谢刘铁锰先生的《深入浅出WPF》，学习WPF过程碰上很多新概念，如Data Binding、路由事件，命令、各种模板等。 WPF：编写CS端的UI技术。 怎么去掉WPF窗体靠上多出黑色的长条？在vs界面的菜单栏点击调试-选项，把启用XAML的UI调试工具勾选去掉即可。(我自己觉得偶尔会用用这个) 1 认识WPF 1.1 新建WPF项目 生成 Properties:...
反序列化的基本使用，is_valid()验证 validators验证器
海里鱼的技术博客
11-04 3302
反序列化使用 验证数据 保存 验证 is_valid() 使用序列化器进行反序列化时，需要对数据进行验证后，才能获取验证成功的数据或保存成模型类对象。 在获取反序列化的数据前，必须调用is_valid()方法进行验证，验证成功返回True，否则返回False。 验证失败，可以通过序列化器对象的errors属性获取错误信息，返回字典，包含了字段和字段的错误。 验证成功，可以通过序列化器对象的validated_data属性获取数据。 在定义序列化器时，指明每个字段的序列化类型和选项参数，本身就是一种验证行
在jsp页面里，引入c标签库后，一写forEach就报错，错误是isValid() == false

&lt;c:forEach&gt;中属性没有加 比如&lt;c:forEach var="" items=""&gt;这样就不会报错了
关于EL表达式- isValid() == false 和- Undefined attribute name的报错

一. 问题描述 在用jsp页面时，jstl的jar全部导入进去了，request域中也有设置了变量A，但是在jsp页面中使用<c:forEach>用EL表达式获取那个变量A却提示Multiple annotations found at this line:- Undefined attribute name "item"的错误 二. 解决方法 经过排错后，发现是<c:forEa...
函数IsValid()

功能：检查对象变量是否已经实例化，即实例变量的值是否是个有效的对象句柄。 语法：IsValid(objectname) 参数：objectname:要检查的对象名。 返回值：Boolean。如果指定对象已经创建了对此案实例，那么IsValid()函数返回True,否则返回FALSE。如果参数obejctname的值为NULL，IsValid()函数返回NULL。 eg:IF IsVa...
is_valid校验机制

先来归纳一下整个流程 （1）首先is_valid()起手，看seld.errors中是否值，只要有值就是flase（2）接着分析errors.里面判断_errors是都为空，如果为空返回self.full_clean()，否则返回self._errors（3）现在就要看full_clean()，是何方神圣了，里面设置_errors和cleaned_data这两个字典，一个存错误字段，一...

 IsValid()功能检查对象变量是否已经实例化即实例变量的值是否是个有效的对象句柄语法IsValid ( objectname )参数objectname 要检测的对象名返回值Boolean 如果指定对象已经创建了对象实例那么IsValid()函数返回TRUE否则返回FALSE 如果参数objectname 的值为NULL IsValid()函数返回NULL示例 下面的代码检查窗口w_emp

功能 检查对象变量是否已经实例化，即实例变量的值是否是个有效的对象。 语法 IsValid(objectname) 参数 objectname:要检查的对象名。 返回值 Boolean。如果指定对象已经创建了对此案实例，那么IsValid()函数返回True,否则返回FALSE。如果参数obejctname的值为NULL，IsValid()函数返回NULL。 示例 if (!isValid(...
is_valid（）判断的是什么，验证的约束条件是以字段的定义为准吗？

数据清洁：如果数据有效，该方法还会“清洁”数据，这意味着它会将数据转化为合适的Python类型。例如，如果一个字段被定义为EmailField，is_valid()会检查该字段中的数据是否是一个有效的电子邮件格式。错误信息：如果某些数据不合法或者缺失必要的数据，is_valid()会返回False，同时，你可以通过form.errors查看具体的错误信息。在Django的表单和模型系统中，每一个字段都有一套默认的验证规则，这些规则是基于字段的类型以及其它属性来定义的。
