Grails将json呈现给特定的视图 [英] Grails rendering json to specific view

问题描述

在一个控制器中，我试图将json呈现给一个特定的视图。这是我在使用json之前所做的：

  def create（）{
 render（view：/ book / create，model：[bookInstance：new Book（params）]）
} 
  

我如何渲染到上面的特定视图，而是返回json？我已经尝试了以下几项：

  def create（）{
 def bookInstance = new Book（params ）
 render（view：/ book / create，model：[bookInstance as JSON]）; 
} 
  

我已经导入了所需的JSON库。

谢谢。

解决方案

模型期待地图。如果没有钥匙，你不能只放任何东西。您的第一个示例具有以下设置：

  render（view：/ book / create，model：[bookInstance：bookInstance as JSON ]）
  

in a controller I am trying to render json to a specific view. Here is what I was doing before using json :

def create() {
    render(view: "/book/create", model: [bookInstance: new Book(params)])
}

How would I render to a specific view like above but return json instead ? I have tried a few things like the following :

def create() {
    def bookInstance = new Book(params)
    render(view:"/book/create", model: [bookInstance as JSON] );
}

I have imported the required JSON library.

Thanks.

解决方案

The model is expecting a map. You can't just put anything in there without a key. Your first example has the setup:

render(view: "/book/create", model: [bookInstance: bookInstance as JSON])
