Trying to get simple example going with no luck.

[aidan james]

Hello,
I need some help getting a simple Test Program that pull a few rows of
data from a running rails app Unfortunately, I cannot seem to get
past the tutorial. The issues I am having appear in searches but
nothing I've tried or found made any difference. I've tried as many of
the similar issues suggestions but it still does not work and I have
no idea why? I tried both the XML and JSon choices. Neither works. The
error messages below.

Can anyone help identify what may be going wrong here??? Thank you.

My client-side model (I've tried to change the type of neighborhoodId
but it did no seem to matter)

@interface Neighborhood : NSObject {
NSString *name;
NSString *description;
NSString *smallImageURL;
NSString *largeImageURL;
NSDate *updatedAt;
NSDate *createdAt;
}

Rails Model:
# == Schema Information
# Schema version: 20110202215058
#
# Table name: neighborhoods
#
# id :integer not null, primary key
# name :string(255)
# description :string(255)
# small_image_url :string(255)
# large_image_url :string(255)
# created_at :datetime
# updated_at :datetime
#

There are two error cases that I am receiving both of which prevent
any data from being seen.

XML - In this case it appears that the data was received. However it
crashes and I don't know why? I have spend a few hours trying various
patches and suggestions but nothing is working.


//loading data in viewController
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];

[ObjectiveResourceConfig setSite:@"http://localhost:3000/"];

//Set the username and password to be used for the remote site
[ObjectiveResourceConfig setUser:@""];
[ObjectiveResourceConfig setPassword:@""];

//Set ObjectiveResource to use either XML or JSON
//[ObjectiveResourceConfig setResponseType:XmlResponse];//the default
[ObjectiveResourceConfig setResponseType:JSONResponse];

neighborhoods = [Neighborhood findAllRemote];
NSLog(@"count = %d", [neighborhoods count]);

}

Is it possible use a NSDate type?

I think you need to use a NSString and then convert ir to a NSDate.

Based on line 6 of the crash backtrace, I'd guess you're trying to
assign a Neighborhood instance to a label by mistake. For example, you
might be doing this:

cell.detailLabel.text = neighborhood;

when you mean to do this:

cell.detailLabel.text = neighborhood.name;

Take a look at your tableView:cellForRowAtIndexPath: method and you'll
probably find the problem.

Also put your neighborhoodId:String in there and dont add the blank username and password. Just delete those lines.

Remove all instances to neiborhood ni your code, except for the viewdidload method.
