RestKit: How can I send object through post protocol in some key? - ios

Question

I want send object through post protocol to server. I use for it RestKit framework.
so, example:
PData *item = [[PData alloc] init];
item.uri = #"http://google.com";
item.status = #"0";
item.updated = [NSDate date];
item.created = [NSDate date];
item.user_id = #"3";
RKObjectManager *sharedManager = RKObjectManager sharedManager;
[sharedManager postObject:item
path:nil
parameters:nil
success:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult) {
[self printPData:mappingResult];
} failure:^(RKObjectRequestOperation *operation, NSError *error) {
NSLog(#"\n\n\n == \nERROE = %#",error);
}];
How can I push json (which consist data of item) in some key ("data")?
(this data on server I can take from $_POST["data"])
How can I do request like this?
{
"data": {
"created": "2014-03-05 14:49:30",
"status": "0",
"updated": "2014-03-05 14:49:30",
"uri": "http:\/\/google.com",
"user_id": "3"
}
}
now, I have had only this:
{
"status": "0",
"updated": "2014-03-05 14:52:17",
"user_id": "3",
"uri": "http:\/\/google.com",
"created": "2014-03-05 14:52:17"
}

Answer 1

It sounds like you haven't specified a key path in your request descriptor. At the moment, somewhere in your code, you'll have something like this:
RKRequestDescriptor *descriptor =
[RKRequestDescriptor requestDescriptorWithMapping:mapping
objectClass:[PData class]
rootKeyPath:nil
method:RKRequestMethodAny];
You need to change it to:
RKRequestDescriptor *descriptor =
[RKRequestDescriptor requestDescriptorWithMapping:mapping
objectClass:[PData class]
rootKeyPath:#"data"
method:RKRequestMethodAny];
That way RestKit will know that PData objects ought to be mapped to the data key path.
