我有一个问题，我正在努力几天。可能是我网站上的一些小东西。
我正在尝试使用 typesafe-reactive 堆栈，从 reactive-mongo-coffeescript 模板开始并对其进行更改。所以，我更改了消息 div 以获取客户详细信息，并更改了后端来获取它。我保留了原始的咖啡脚本代码（也许这就是问题......）。
咖啡脚本：
require(["webjars!knockout.js", 'webjars!jquery.js', "/routes.js", "webjars!bootstrap.js"], (ko) ->
messagesPerPage = 10
# Models for the customer page
class CustomerModel
constructor:() ->
self = @
# the messages field that first name is entered into
@firstNameField = ko.observable()
# the messages field that middle name is entered into
@midNameField = ko.observable()
# the messages field that last name is entered into
@lastNameField = ko.observable()
# the messages field that address line 1 is entered into
@addressOneField = ko.observable()
# the messages field that address line 2 is entered into
@addressTwoField = ko.observable()
# the messages field that address line 3 is entered into
@addressThreeField = ko.observable()
# the messages field that city is entered into
@cityField = ko.observable()
# the messages field that state is entered into
@stateField = ko.observable()
# the messages field that zip code is entered into
@zipField = ko.observable()
# the messages field that country is entered into
@countryField = ko.observable()
# the messages field that phone is entered into
@phoneField = ko.observable()
# the messages field that email is entered into
@emailField = ko.observable()
# save a new customer
@saveCustomer = () ->
alert("saving")
data: JSON.stringify({
firstName: @firstNameField()
midName: @midNameField()
lastName: @lastNameField()
addr1: @addressOneField()
addr2: @addressTwoField()
addr3: @addressThreeField()
city: @cityField()
state: @stateField()
zip: @zipField()
country: @countryField()
email: @emailField()
phone: @phoneField()
})
alert(data)
@ajax(routes.controllers.CustomerController.saveCustomer(), {
contentType: "application/json"
}).done(() ->
alert("done saving")
$("#addCustomerModal").modal("hide")
self.firstNameField(null)
)
# Models for the messages page
class MessagesModel
constructor: () ->
self = @
# the list of messages
@messages = ko.observableArray()
# the messages field that messages are entered into
@messageField = ko.observable()
# the URL to fetch the next page of messages, if one exists
@nextMessagesUrl = ko.observable()
# the URL to fetch the previous page of messages, if one exists
@prevMessagesUrl = ko.observable()
# save a new message
@saveMessage = () ->
@ajax(routes.controllers.MessageController.saveMessage(), {
data: JSON.stringify({
message: @messageField()
})
contentType: "application/json"
}).done(() ->
$("#addMessageModal").modal("hide")
self.messageField(null)
)
# get the messages
@getMessages = () ->
@ajax(routes.controllers.MessageController.getMessages(0, messagesPerPage))
.done((data, status, xhr) ->
self.loadMessages(data, status, xhr)
)
# get the next page of messages
@nextMessages = () ->
if @nextMessagesUrl()
$.ajax({url: @nextMessagesUrl()}).done((data, status, xhr) ->
self.loadMessages(data, status, xhr)
)
# get the previous page of messages
@prevMessages = () ->
if @prevMessagesUrl()
$.ajax({url: @prevMessagesUrl()}).done((data, status, xhr) ->
self.loadMessages(data, status, xhr)
)
# Convenience ajax request function
ajax: (route, params) ->
$.ajax($.extend(params, route))
# Handle the messages response
loadMessages: (data, status, xhr) ->
@messages(data)
# Link handling for paging
link = xhr.getResponseHeader("Link")
if link
next = /.*<([^>]*)>; rel="next".*/.exec(link)
if next
@nextMessagesUrl(next[1])
else
@nextMessagesUrl(null)
prev = /.*<([^>]*)>; rel="prev".*/.exec(link)
if prev
@prevMessagesUrl(prev[1])
else
@prevMessagesUrl(null)
else
@nextMessagesUrl(null)
@prevMessagesUrl(null)
# Setup
# model = new MessagesModel
model = new CustomerModel
ko.applyBindings(model)
# Load messages data
# model.getMessages()
# Server Sent Events handling
events = new EventSource(routes.controllers.MainController.events().url)
events.addEventListener("message", (e) ->
# Only add the data to the list if we're on the first page
if model.prevMessagesUrl() == null
message = JSON.parse(e.data)
model.messages.unshift(message)
# Keep messages per page limit
if model.messages().length > messagesPerPage
model.messages.pop()
, false)
)
saveCustomer 末尾的 alert("saving") 弹出，所以它到达那里，而 ajax 的 done() 子句中的 alert("saving") 没有，这让我相信问题出在 json.stringify .
客户创建 div：
@* createCustomerDiv Template File *@
@(customer: Option[models.Customer])
<div class="modal fade" id="addMessageModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

最后是处理程序方法。记录器没有记录任何东西，所以我假设这里没有发送呼叫：
/**
* The customer form. This is separate from the database customer since the form doesn't have an ID.
*/
case class CustomerForm(
firstName: String,
midName: Option[String],
lastName: String,
addr1: String,
addr2: Option[String],
addr3: Option[String],
city: String,
state: String,
zip: String,
country: String,
email: String,
phone: String
) {
val name = Name(firstName, midName, lastName)
val eml = Email(email)
val cntry = Country(country)
val address = Address(BSONObjectID.generate, addr1, addr2, addr3, city, state, zip, cntry)
val phn = Phone(1,2,3)
def toCustomer: Customer = Customer(BSONObjectID.generate, name, eml, phn, address)
}
implicit val customerFormFormat = Json.format[CustomerForm]
/** Action to save a message */
def saveCustomer = Action(parse.json) { req =>
Logger.debug("saveCustomer called")
Json.fromJson[CustomerForm](req.body).fold(
invalid => BadRequest("Bad message form"),
form => Async {
CustomerDao.save(form.toCustomer).map(_ => Created)
}
)
}
}
任何见解都会有所帮助。谢谢。
