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} && ${bar}" th:action="@{/foo}" method="post">
<input type="text" th:field="*{name}"/>
<input type="text" th:field="*{status}"/>
<button type="submit">Go</button>
</form>
So far I tried to do with to fieldset with a th:object in it, that doesn't work, I tried to put two th:object in the form, that doesn't work either.
The only way I found is to build an other object containing those two objects, and pass it. That works well, but I can't create that kind of object, it's nonsense (even if it works).
Of course, the objects aren't as simple as Foo and Bar here, otherwise I would have merge those two. But that's not something I can do.
Is it even possible to pass two objects like that to use in a form?
Thanks already.
I don't think you need to use two th:objects
. Just use th:value
<form th:action="@{/foo}" method="post">
<input type="text" th:value="${foo.name}" name="name"/>
<input type="text" th:value="${bar.status}" name="status"/>
<button type="submit">Go</button>
</form>
I would think Spring is smart enough, on the controller side, to use its mapping techniques to map your fields to their proper command object, foo or bar.
i used a div tag to surround the form input for my second object and added a th:object..... the controller processed it and added it to the database.
<form method=post th:object="${object1}" >
<div th:object="${object2}" >
code......
</div>
<input type="submit" />
</form>
I think the most elegant way to accomplish your result is reported here: Adding multiple objects with the same name fields using Thymeleaf/Spring Boot
The other solutions work if the two objects do not have fields with the same name.
