我创建了一个表格来绑定到数据表请求:
val datatableForm = Form(
tuple(
"draw" -> number,
"start" -> number,
"length" -> number,
"search" -> tuple(
"value" -> text,
"regex" -> boolean
),
"columns" -> seq(tuple(
"data" -> number,
"name" -> text,
"orderable" -> boolean,
"search" -> tuple(
"value" -> text,
"regex" -> boolean
)
)
),
"order" -> seq(tuple(
"column" -> number,
"dir" -> text
)
)
)
)
在我的请求中,我致电
val form = datatableForm.bindFromRequest
。这对于draw
,start
和length
变量非常有效,但对于search
,columns
和order
变量却无效。例如,当我不使用嵌套元组时,可以调用datatableForm.bindFromRequest.get
,它将返回Some
对象,但是当我添加嵌套元组并调用get
时,它将返回None
对象。从datatables javascript对象发送的数据是:
{
"draw": 1,
"columns": [
{
"data": 0,
"name": "",
"searchable": true,
"orderable": true,
"search": {
"value": "",
"regex": false
}
},
{
"data": 1,
"name": "",
"searchable": true,
"orderable": true,
"search": {
"value": "",
"regex": false
}
}
],
"order": [
{
"column": 0,
"dir": "asc"
}
],
"start": 0,
"length": 10,
"search": {
"value": "",
"regex": false
}
}
这是请求正文中的数据:
Map(draw -> ArrayBuffer(1), columns[0][data] -> ArrayBuffer(0), columns[0][name] -> ArrayBuffer(), columns[0][searchable] -> ArrayBuffer(true), columns[0][orderable] -> ArrayBuffer(true), columns[0][search][value] -> ArrayBuffer(), columns[0][search][regex] -> ArrayBuffer(false), columns[1][data] -> ArrayBuffer(1), columns[1][name] -> ArrayBuffer(), columns[1][searchable] -> ArrayBuffer(true), columns[1][orderable] -> ArrayBuffer(true), columns[1][search][value] -> ArrayBuffer(), columns[1][search][regex] -> ArrayBuffer(false), order[0][column] -> ArrayBuffer(0), order[0][dir] -> ArrayBuffer(asc), start -> ArrayBuffer(0), length -> ArrayBuffer(10), search[value] -> ArrayBuffer(), search[regex] -> ArrayBuffer(false))
如何获取表格绑定到嵌套元组?
最佳答案
我看到了同样的错误。问题是请求没有作为json
发送。确保将contentType
设置为json
。
如果您使用的是jQuery,则文档位于here中,以了解有关操作方法。
本质上是这样的:
$.ajax({
type: "POST",
url: youUrl,
data : data,
contentType: "application/json"
});
