如何通过两种物体在使用百里香的形式中使用？ [英] How to pass two objects to use in a form using thymeleaf?

问题描述

我的问题如下：

我有2个不同的对象，我必须从单个窗体中填充。

使用1个对象，我只需在newFoo.html中完成：

 < form th：object =$ {foo} th：action =@ {/ foo}method =post> 
< input type =textth：field =* {name}/> 
< / form> 
< / code>< / $ p"按钮类型=提交>前往< /按钮> $ p 
 
 
和在FooController中：
 
 pre $  @RequestMapping（value =/ foo / new，method = RequestMethod.GET）
 public String newFoo（final Foo foo，Model model）{
 returnnewFoo; 
} 
 
 @ RequestMapping（value =/ foo / new，method = RequestMethod.POST）
 public String saveFoo（final Foo foo，final BindingResult bindingResult，Model model）{
 fooService.save（foo）; 
 returnredirect：/ foo / new; 
} 
  

还有一个带有状态变量的其他对象栏，我该怎么做才能传递这个对象，这样我才能在同一个表单中提交输入

 < form th：object = $ {foo}&& $ {bar}th：action =@ {/ foo}method =post> 
< input type =textth：field =* {name}/> 
< input type =textth：field =* {status}/> 
< button type =submit> Go< / button> 
< / form> ; 
  

到目前为止，我试图用field中的一个th：object对象进行设置，我尝试在表单中放置两个th：object，这也是行不通的。

我发现的唯一方法是构建一个包含这些对象的对象两个对象，并通过它，这很好，但我不能创建这种类型的对象，这是无稽之谈（即使它的工作原理）。

当然，对象并不像Foo和Bar那么简单，否则我会合并这两个。但那不是我能做到的。

是否有可能通过两个这样的对象在表单中使用？

已经感谢您。

解决方案

<我不认为你需要使用两个 th：objects 。只需使用 th：value

 < form th：action = @ {/ foo}method =post> 
< input type =textth：value =$ {foo.name}name =name/> 
< input type =textth：value =$ {bar.status}name =status/> 
< button type =submit> Go< / button> 
< / form> 
  

我认为Spring在控制器方面足够智能，可以使用它的映射技术来映射字段到他们正确的命令对象，foo或bar。

My problem is the following :

I've 2 differents objects that I've to fill from a single form.

With 1 object, I simply do in the newFoo.html :

<form th:object="${foo} th:action="@{/foo}" method="post">
      <input type="text" th:field="*{name}" />
      <button type="submit">Go</button>
</form>

and in the FooController :

@RequestMapping(value = "/foo/new", method = RequestMethod.GET) 
    public String newFoo(final Foo foo, Model model) { 
        return "newFoo"; 
    } 

@RequestMapping(value = "/foo/new", method = RequestMethod.POST) 
    public String saveFoo(final Foo foo, final BindingResult bindingResult, Model model) { 
        fooService.save(foo); 
        return "redirect:/foo/new"; 
    } 

Let's say I've an other object bar with a "status" variable in it. How can I do to pass that object so I can submit the input within the same form ?

Like :

<form th:object="${foo} && ${bar}" th:action="@{/foo}" method="post">
      <input type="text" th:field="*{name}" />
      <input type="text" th:field="*{status}" />
      <button type="submit">Go</button>
</form>

So far I tried to do with to fieldset with a th:object in it, that doesn't work, I tried to put two th:object in the form, that doesn't work either.

The only way I found is to build an other object containing those two objects, and pass it. That works well, but I can't create that kind of object, it's nonsense (even if it works).

Of course, the objects aren't as simple as Foo and Bar here, otherwise I would have merge those two. But that's not something I can do.

Is it even possible to pass two objects like that to use in a form ?

Thanks already.

解决方案

I don't think you need to use two th:objects. Just use th:value

<form th:action="@{/foo}" method="post">
      <input type="text" th:value="${foo.name}" name="name"/>
      <input type="text" th:value="${bar.status}" name="status"/>
      <button type="submit">Go</button>
</form>

I would think Spring is smart enough, on the controller side, to use its mapping techniques to map your fields to their proper command object, foo or bar.
