Database connection failure

2011-09-22 Thread Rishab Jain
Hi guys,

To connect to a database, I have 2 hostnames which can be connected
to. Both of them carry the same data. Basically they're used to
balance the load. I can set the data source to any one of them. I'm
able to do that.

However, my problem is that, in case any of the hosts go down, I
should be able to connect immediately to the other one. I mean how do
I overload the app_model.php in such a way, that I should know
immediately that the connection didn't get established, and I should
connect to the other host.

Can anybody help me with this?

regards,
Rishab

Re: Issue with getNumRows

2011-05-03 Thread Rishab Jain
Well I agree it might not be a bug, however, I really don't understand the
need to have execute a find('count) function again to fetch the total number
of rows. I'm not getting into pagination coz I've already built something
and don't have the time now to move on to the cake pagination. I just wanted
to know if there's another function just like getNumRows() which could
provide me with the total rows selected for that particular where clause.

Rishab

How to use a function of a controller from another controller

2011-04-11 Thread Rishab Jain
Hi all,

There's a controller:

class PhotosController extends AppController {
var $name = 'Photos';

   function index()
   {
  // I need to call the method getAllUsers() of the Users
Controller here.
   }
}


And, there's another controller.

class UsersController extends AppController {
var $name = 'Users';

   function index()
   {

   }

   function getAllUsers($userid)
   {
// get the array for all the users from the database
and return the same.
   }
}

===

Can anybody tell me how can this be done. I tried searching on the
internet, where people say that there are 2 ways of doing this.

===
1.  App::import('Controller', 'Posts');

  class CommentsController extends AppController {
//Instantiation
$Posts = new PostsController;
//Load model, components...
$Posts->constructClasses();

function index($passArray = array(1,2,3)) {
  //Call a method from PostsController with parameter
  $Posts->doSomething($passArray);
}
  }
===
2. Making it a model.

===

I get an error trying the first alternative. And I dont want to make
the function in the model. Let me know how can we do this.

regards,
Rishab

thumbnail generator

2011-04-08 Thread Rishab Jain
Hi,

I tried so many thumbnail generators available over internet. But none
of them proved to be of a good quality.

I need a thumbnail generator which I can use to generate 2 separate
copies the image uploaded of 2 different sizes.

Has someone used any generator in cakephp?

Re: multiple file upload in php

2011-03-31 Thread Rishab Jain
Hi,

This works fine when I created a non-cakephp based setup. However, when I
try to use it in a cake based setup, it gives me an error. After almost an
hour of debugging, I saw that the problem lies in,

$('#file_upload').uploadify({
  'uploader'  : 'path_to_uploadifyswf/uploadify.swf',
  'script': 'http://dev.mydomain.com/multiupload/',
  'cancelImg' : 'pathtoimages/cancel.png',
  'folder': 'uploaded_files',
  'multi'   : true,

Here, when I give the script URL to be of an action of a controller, it
gives me a 302 Error. However, when I change it to
  'script': '
http://dev.mydomain.com/non_cake_based_setup/multiupload.php',

It works then.

Really have no idea about this behaviour. Anybody having any idea here?

regards,
Rishab

multiple file upload in php

Hi,

Does anybody know of a good multiple file upload in cakephp (or even php for
that matter). I'm not looking for many input tags for upload, but for an
interface where I can upload many files in one go.

And it should be a freeware.

issues with document root and rewrite urls

2011-03-28 Thread Rishab Jain
Hi,

I have a setup where I want the document root to set to the main
directory where my application is residing.

Currently, the path to my directory is something like this:
/var/www/html/dev.mydomain.com/aaa/code_project/
   app/
   cake/
   index.php
   plugins
   README
   vendors

Now the point where all this started was when I was writing URLs for
my navigation tabs.

For eg, to access the tab 'inbox', I wanted to write the URL in the
file to be was '/inbox/'. But when I did that, the URL actually
pointed to http://dev.mydomain.com/inbox/. I guess that means my
document root is not pointing to the code_project directory but to the
dev.mydomain.com directory.

I wrote the following line in the .htaccess file,


   RewriteEngine on
   RewriteRule^$ app/webroot/[L]
   RewriteRule(.*) app/webroot/$1 [L]

  # this line was added by me
 #DocumentRoot /var/www/html/dev.mydomain.com/aaa/bbb/code_project/app/webroot/


But, when I tried accessing the url, it gave me a 500 error.

Can anybody help me gaining knowledge of how exactly this thing works
and how to set it all up?

Thanking you guys in advance and looking forward to some replies.

regards,
Rishab

issue with saving data in model

2011-03-28 Thread Rishab Jain
Hi All,

I'm facing a very weird problem. I'm trying to save data in a loop
where 1 person is sending msg to many people.. Here's the print_r of
the 3 arrays before I call the 'save' function in the model.

Array
(
[Message] => Array
(
[sender_uid_fk_users] => 1
[subject] => hey
[body] => hey
[recipient_uid_fk_users] => 2
[date] => 2011:03:28 10:52:41
)

)
Array
(
[Message] => Array
(
[sender_uid_fk_users] => 1
[subject] => hey
[body] => hey
[recipient_uid_fk_users] => 4
[date] => 2011:03:28 10:52:41
)

)
Array
(
[Message] => Array
(
[sender_uid_fk_users] => 1
[subject] => hey
[body] => hey
[recipient_uid_fk_users] => 6
[date] => 2011:03:28 10:52:41
)

)

The only difference here is the different 'recipient_uid_fk_users' in
all the 3 arrays with values '2', '4', and, '6'.

All I'm doing then is,
foreach(recipient...)
{
/// prepare $arrayMessagesInfo /
 $this->save($arrayMessagesInfo);
}

The issue I'm facing is that only the first value gets inserted, and
the rest of the two queries becomes 'update' queries. I'm not even
mentioning the primary key in the array.

These are the cakephp debugging logs:

4   INSERT INTO `messages` (`sender_uid_fk_users`, `subject`,
`body`, `recipient_uid_fk_users`, `date`) VALUES (1, 'hey', 'hey', 2,
'2011:03:28 10:48:33')1   0
5   SELECT LAST_INSERT_ID() AS insertID 1   1   0
6   SELECT COUNT(*) AS `count` FROM `messages` AS `Message` WHERE
`Message`.`id` = 31   1   0
7   SELECT COUNT(*) AS `count` FROM `messages` AS `Message` WHERE
`Message`.`id` = 31   1   0
8   UPDATE `messages` SET `sender_uid_fk_users` = 1, `subject` =
'hey', `body` = 'hey', `recipient_uid_fk_users` = 4, `date` =
'2011:03:28 10:48:33' WHERE `messages`.`id` = 3   1
   0
9   SELECT COUNT(*) AS `count` FROM `messages` AS `Message` WHERE
`Message`.`id` = 31   1   0
10  SELECT COUNT(*) AS `count` FROM `messages` AS `Message` WHERE
`Message`.`id` = 31   1   0
11  UPDATE `messages` SET `sender_uid_fk_users` = 1, `subject` =
'hey', `body` = 'hey', `recipient_uid_fk_users` = 6, `date` =
'2011:03:28 10:48:33' WHERE `messages`.`id` = 3

Here's the table structure:
 CREATE TABLE `messages` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `subject` varchar(100) NOT NULL,
  `body` varchar(500) NOT NULL,
  `sender_uid_fk_users` int(10) unsigned NOT NULL,
  `date` datetime NOT NULL,
  `recipient_uid_fk_users` int(10) unsigned NOT NULL,
  PRIMARY KEY (`id`),
  KEY `sender_uid_fk_users` (`sender_uid_fk_users`),
  KEY `recipient_uid_fk_users` (`recipient_uid_fk_users`),
) ENGINE=MyISAM DEFAULT CHARSET=latin1 |


It would be great if anybody can help me out here.
