Yii retain speed when using Javascript

Leave a reply

CClientScript can be useful for including css files and javscript files, while avoiding duplication, you only need to learn and control the darn thing right.

Before we begin or if you tried it already and have come searching for this:

1. Yii writes the code for css files just above thetag in the html document. So, if you want to override, put your
or (preferred) AFTER the

2. I recommend putting all your
and in theand all your just before . are blocking, so your page will load faster if the are at the bottom. use:

1 Yii::app()->getClientScript()->coreScriptPosition = CClientScript::POS_END;

3. If you want to include some inline javascript in a view, but make it load at the bottom, after say jquery, use the registerScript() method.

1 /* load some formatted js into a php variable: */
2 $js = <<<EOF
3 var = 'some javascript here!';
4     function() { return 'you can format it as you like, and include php $variables'; };
5 EOF;
6  
7 /* write the script at the bottom of the document  */
8 Yii::app()->getClientScript()->registerScript("some id", $js, CClientScript::POS_END);

A possible solution to having an tree type display of a nestled structure in a dropDownlist or activeDropDownList.

01 public static function getListModulesTreeView() {
02         return self::visualTree(SystemModules::model()->findAll('moduleIdFk is NULL'), 0);
03     }

05     private static function visualTree($moduleTree, $level) {

07         $results = array(0=>Yii::t('gui', 'noSubmodules'));

MAMP Pro & MySQL workbench

Leave a reply

I’ve been looking for a few hours for a quick and easy solution to my connection problem between MySQL workbench and the database itself using MAMP Pro. In itself it isn’t a real problem because you have phpMyAdmin readily available but for ERD models and reverse engineering options. I found my answer on stackoverflow without a lot of trouble but it was a hasty answer and I like to explain a bit complete. So here goes.

First open MAMP Pro on your Mac and you’ll see the following image

See to it that your ports are the same as mine or adjust accordingly if you want to keep them.

Next you will need to open workbench, I Presume you have it already installed in your Mac. The first thing you’ll have, is the possibility to create a connection or edit one if you have tried and failed as I have before. open or create the connection that you want to establish but can’t. You’ll get something along these lines, if not, please search for it.

When you have the first form filled out correctly go to ‘Advanced’ in the same window!

In the ‘Others’ section you will have to add a line and you’ll be good to go. You have to add: socket=/Applications/MAMP/tmp/mysql/mysql.sock and go back to the ‘Parameters’ and use ‘test connection’, normally this should have you up and running. If not, is MAMP started? Are your ports correctly configured? User/password? ….

Module and submodule in Yii framework

Leave a reply

Yii framework is a very fast and usable framework, within you can create modules to house some sort of sub-applications, link a forum for example but how do you make use of sub-modules?

First you need to create the top most modules, in my case ‘main’. You can do this by using the Gii tool to generate it. After this you need to add the created module to the config/main.php

 PHP |   copy code | ?  
01 'modules' => array(
02         'gii' => array(
03             'class' => 'system.gii.GiiModule',
04             'password' => 'admin',
05             'generatorPaths' => array(
06                 'bootstrap.gii'
07             ),
08         ),
09         // main application components
10         'main',
11     ),

After this you can create the submodules by using Gii, don’t forget to do it like this main/NewModuleName, the system then knows where to place them.

And now we go back to the config/main.php

 PHP |   copy code | ?  
01 'modules' => array(
02 'gii' => array(
03 'class' => 'system.gii.GiiModule',
04 'password' => 'admin',
05 'generatorPaths' => array(
06 'bootstrap.gii'
07 ),
08 ),
09 // main application components
10 'main'=>array('NewModuleName1','...'),
11 ),

Firefox: new tab page tweak

Leave a reply

I use Firefox daily in my browsing and i like the new tab page a lot but 9 sites doesn’t cut it for me anymore so it was time to tweak things a bit.

Firefox uses an internal database to store it’s configuration values an that’s where you’ll need to go: type in the address bar: “about:config”. Firefox will warn you and just click “ok” but be careful anyway. now search for “browser.newtabpage.”, there you’ll have not more then 10 results, search for rows and columns with their standard value 3.

You’ll want to have a grid, I did the following, columns = 5 and rows = 4, everything is smaller but still readable and not more taxing on the browser itself.

Tor: Vidalia Tor software exited unexpectedly

Leave a reply

With the latest developments in internet censorship I too have been looking for secure alternatives and the Tor project is one of them but unfortunately I had a small problem with Vidalia, the software GUI for Tor. I discovered a solution after some reading and Google-ing.

After installing Tor on ubuntu or other Debian based distributions and running it for the first time you probably are getting the following error:

Vidalia detected that the tor software exited unexpectedly.

Please check the message log for recent warning or error messages.

Alright, now on to the solution. You best open up a terminal because it’s going to require some command-line work, first thing you should do is make sure that everything Tor isn’t running anymore, so copy/past this in your terminal:

 Bash |   copy code | ?  
1 sudo killall tor

and enter your password when asked after having hit the ‘enter’ button. Don’t exit the terminal window just yet because you’ll need it a bit more. Now that you have killed off all the possible running tor-processes you can fix the real problem.

Upon installation, tor will automatically starts up when booting Ubuntu. When you open Vidalia, it will first check if there is an existing tor process and try to connect to the control port of tor. All you need to do is reconfigure tor so it allows Vidalia to connect and start using the tor process correctly without throwing the error.

First step: is to open the configuration file of tor. Open a terminal and execute the following command: (note: sudo is required or you won’t be able to save the file later on)

sudo gedit /etc/tor/torrc

Gedit is standard installed on Ubuntu and a lot of other distributions, and my favorite but if you have another just replace gedit by that one in the command-line. Also check your preferences so that the editor displayed line numbers it will make this easier.

After the file opens, scroll down to line 53 to line 60 and you will see something like this:

 Bash |   copy code | ?  
1 ## The port on which Tor will listen for local connections from Tor
2 ## controller applications, as documented in control-spec.txt.
3 #ControlPort 9051
4 ## If you enable the controlport, be sure to enable one of these
5 ## authentication methods, to prevent attackers from accessing it.
6 #HashedControlPassword 16:872860B76453A77D60CA2BB8C1A7042072093276A3D701AD684053EC4C #CookieAuthentication 1

Now modify this so that you have something that looks like this:

 Bash |   copy code | ?  
1 ## The port on which Tor will listen for local connections from Tor
2 ## controller applications, as documented in control-spec.txt.
3 ControlPort 9051
4 ## If you enable the controlport, be sure to enable one of these
5 ## authentication methods, to prevent attackers from accessing it.
6 HashedControlPassword 16:D11E80307FCD1E730083FA68F6650BDBC2FE1D3BA100C07A7895CFC4D1
7 #CookieAuthentication 1

What have you done? You set the control port so vidalia can take control of tor and you initiated the password authentication. Now you just have to run one other command, so open a secondary terminal, you’ll need it because your current one is running gedit.

 Bash |   copy code | ?  
1 tor --hash-password mypassword

Now the result of this command is something like this: (note: don’t past my result, make your own for security reasons)

 Bash |   copy code | ?  
1 webscriptz@webscriptz-hp:~$ tor --hash-password mypassword
2 May 06 12:49:45.190 [notice] Tor v0.2.2.35 (git-73ff13ab3cc9570d). This is experimental software. Do not rely on it for strong anonymity. (Running on Linux x86_64)
3 16:E499E055BC335107609A1E2A0D857422E238376BEA3B75F35E50C376A6

This part you need is :

 Bash |   copy code | ?  
1 16:E499E055BC335107609A1E2A0D857422E238376BEA3B75F35E50C376A6

You need to insert this on line 68 after:

 Bash |   copy code | ?  
1 HashedControlPassword

Now for the final step you need to restart Tor:

 Bash |   copy code | ?  
1 sudo /etc/init.d/tor restart

Now open vidalia and start Tor, it should work, if not close vidalia and re-open it again and everything should be fine.
