Hello guys,
I have a many-to-many relationship between two mappers called, Users
and Devices.
There is also an API that receives and XML message that contains one
user and one device.
The API could create the Device and User with the relationship or it
could create only the relationship in case the users and/or device
already exists.
The problem I have is that the API creates the User and the Device,
but the not the relationship. This is the code that saves the records
(just a test for a now):
def addUser(req: Req): LiftResponse = {
var tempUserName = ""
var tempDeviceName = ""
var deviceAlreadyExists = false
val newUser = new User
val newDevice = new Device
req.xml match {
case Full(<person>{parameters @_*}</person>) => {
for(parameter <- parameters){ parameter match {
case <userName>{userName}</userName> =>
tempUserName = userName.text
case <firstName>{firstName}</firstName>
=> newUser.firstName(firstName.text)
case <lastName>{lastName}</lastName> =>
newUser.lastName(lastName.text)
case <password>{password}</password> =>
newUser.password(password.text)
case <email>{email}</email> =>
newUser.email(email.text)
case <createdon>{createdOn}</createdon>
=> newUser.createdOn(new java.util.Date(createdOn.text))
case <updatedon>{updatedOn}</updatedon>
=> newUser.updatedOn(new java.util.Date(updatedOn.text))
case <device>{deviceName}</device> =>
tempDeviceName = deviceName.text
case _ =>
}
}
try {
Device.find(By
(Device.deviceName,tempDeviceName)) match {
case Full(deviceRequested) =>
deviceAlreadyExists = true
case _ => {
newDevice.deviceName
(tempDeviceName)
newDevice.createdBy(tempUserName)
newDevice.createdOn
(newUser.createdOn)
newDevice.updatedBy(tempUserName)
newDevice.updatedOn
(newUser.updatedOn)
newDevice.save
}
}
User.find(By(User.userName, tempUserName))
match {
case Full(userRequested) =>
CreatedResponse(wrapXmlBody
(<operation id="addPerson" success="1"></operation>), "text/xml")
case _ => {
newUser.userName(tempUserName)
newUser.createdBy(tempUserName)
newUser.updatedBy(tempUserName)
newUser.devices.clear
newUser.validated(true)
newUser.devices += newDevice
newUser.save
CreatedResponse(wrapXmlBody
(<operation id="addPerson" success="0"></operation>), "text/xml")
}
}
}
catch {
case e => Log.error("Could not add person/
device", e); BadResponse()
}
}
case _ => Log.error("Request was malformed "+req.view);
BadResponse()
}
}
The field "devices" is the MappedManyToMany field within the User
mapper.
What am I doing wrong?
Thanks in advance,
GA
