Ruby on Rails and Cocoa - POST puts values into DB as NULL

I am trying to send a POST request to my Ruby on Rails local server. Unfortunately, at first it wouldn't let me POST because of protect_from_forgery, so I ended up setting it to false in development and production. Basically, my issue is that I'll send the POST request from my Cocoa app with all of the wanted params, and the Ruby server will see it. However, whenever the server inserts my request all of the VALUES are set to NULL with the exception of created_at and updated_at. I do not know how Ruby on Rails works (since I used scaffold), so I am not sure where I need to set the params so that they will be inserted properly.

Thanks!

COCOA CODE:

NSString *urlString = @"http://localhost:3000/clients";
NSURL *url = [[NSURL alloc] initWithString:urlString];
NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL: url];
[req setHTTPMethod: @"POST"];

NSData *putParams = [@"name=TEST&ip_address=1.1.1.1" dataUsingEncoding:NSUTF8StringEncoding];
[req setHTTPBody: putParams];   

NSHTTPURLResponse* urlResponse = nil;  
NSError *error = [[NSError alloc] init];  
NSData *responseData = [NSURLConnection sendSynchronousRequest:req returningResponse:&urlResponse error:&error];  
NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];

NSLog(@"Response Code: %d", [urlResponse statusCode]);
if ([urlResponse statusCode] >= 200 && [urlResponse statusCode] < 300)
    NSLog(@"Response: %@", result);

[url release];
[req release];
[error release];

SERVER RESPONSE:

I TRIED TO DO THIS IN CLIENTS CONTROLLER BUT ISSUE REMAINED THE SAME:

if params[:name].present?
  @client = Client.new(:name => params[:names])
else
  @client = Client.new(params[:client])
end

JUST IN CASE IT IS NEEDED (FULL CLIENT CONTROLLER - ALL OF IT WAS WITH SCAFFOLD):

class ClientsController < ApplicationController

# GET /clients
# GET /clients.xml
def index
  @clients = Client.all

  respond_to do |format|
    format.html # index.html.erb
    format.xml  { render :xml => @clients }
  end
end

# GET /clients/1
# GET /clients/1.xml
def show
  @client = Client.find(params[:id])

  respond_to do |format|
    format.html # show.html.erb
    format.xml  { render :xml => @client }
  end
end

# GET /clients/new
# GET /clients/new.xml
def new
  @client = Client.new

  respond_to do |format|
    format.html # new.html.erb
    format.xml  { render :xml => @client }
  end
end

# GET /clients/1/edit
def edit
  @client = Client.find(params[:id])
end

# POST /clients
# POST /clients.xml
def create
  if params[:name].present?
    @client = Client.new(:name => pa开发者_如何学Gorams[:names])
  else
    @client = Client.new(params[:client])
  end

  respond_to do |format|
    if @client.save
      format.html { redirect_to(@client, :notice => 'Client was successfully created.') }
      format.xml  { render :xml => @client, :status => :created, :location => @client }
    else
      format.html { render :action => "new" }
      format.xml  { render :xml => @client.errors, :status => :unprocessable_entity }
    end
  end
end

# PUT /clients/1
# PUT /clients/1.xml
def update
  @client = Client.find(params[:id])

  respond_to do |format|
    if @client.update_attributes(params[:client])
      format.html { redirect_to(@client, :notice => 'Client was successfully updated.') }
      format.xml  { head :ok }
    else
      format.html { render :action => "edit" }
      format.xml  { render :xml => @client.errors, :status => :unprocessable_entity }
    end
  end
end

# DELETE /clients/1
# DELETE /clients/1.xml
def destroy
  @client = Client.find(params[:id])
  @client.destroy

  respond_to do |format|
    format.html { redirect_to(clients_url) }
    format.xml  { head :ok }
  end
end

end

P.S. If something about my question is unclear, please let me know.

You have a typo in your controller: @client = Client.new(:name => params[:names]) should be @client = Client.new(:name => params[:name]).

That would solve part of the issue but here is the root of it:

Essentially, if this were a "real" Rails app it would send params like this:

{ :client => { :name => x, :ip => y } }

And then you could access the name and IP in params[:client] like so:

@client = Client.new(params[:client])

But you are sending:

{ :name => x, :ip => y }

So you need:

@client = Client.new(:name => params[:name], :ip => params[:ip])

For the "Rails way" to work, you could modify your Objective-C code to send params like client[name]=x&client[ip]=y.
