AFNetworking + AFJSONRequestOperation + Rails - ruby-on-rails

Question

I'm using NSMutableURLRequest before using AFJSONOperationRequest and I have a problems getting the data in my Rails app.
If I use :
NSMutableURLRequest *request = [[HTTPClient sharedClient] multipartFormRequestWithMethod:#"POST" path:path parameters:dict constructingBodyWithBlock: ^(id <AFMultipartFormData>formData)
{
}];
Then :
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
{
else {
}
}
I get my data correctly formatted in the Rails logs:
Parameters: {"contact"=>{"country_id"=>"45", "lastname"=>"Tutu"}}
But I don't need AFMultipartFormData to send a file... (no file to send)
So, instead, I use:
NSMutableURLRequest *request = [[HTTPClient sharedClient] multipartFormRequestWithMethod:#"POST" path:path parameters:dict];
with my AFJSONRequestOperation too. But, my parameters are now not set correctly in my rails app:
Parameters: {contact[country_id] => "45", contact[lastname] => "Tutu"}
instead of
Parameters: {"contact"=>{"country_id"=>"45", "lastname"=>"Tutu"}}
I don't understand why. It looks like the body of the request is not set correctly when I don't use the block: "constructingBodyWithBlock".

Don't use multipartFormRequestWithMethod.
Just use the postPath method like this
[[YourHTTPClient sharedClient] postPath:path
parameters:dict
success:^(AFHTTPRequestOperation *operation, NSString* path){
}
failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
Edit:
If you need an operation use AFJSONRequestOperation directly
+ (AFJSONRequestOperation *)JSONRequestOperationWithRequest:(NSURLRequest *)urlRequest
success:(void (^)(NSURLRequest *request, NSHTTPURLResponse *response, id JSON))success
failure:(void (^)(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON))failure;
NSURL *url = [NSURL URLWithString:#"http://yoursite.com/path"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
AFJSONRequestOperation * operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request
success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
}];
