Using Symfony2 with Backbone.js

2012-10-29T11:15:00.000-07:00

Inspired by some of the Symfony Live San Francisco talks , I decided to create this bundle and become a better OSS contributor.

This bundle allows you to easily start a backbone.js project with Symfony2, it creates a basic structure for your backbone files and also includes a generator to scaffold your backbone classes.

All the installation steps can be found in the README: https://github.com/gigo6000/DevtimeBackboneBundle

A simple Raffler app created with this bundle can be found here: https://github.com/gigo6000/DevtimeRafflerBundle

Symfony2 FOSTwitterBundle TwitterProvider

2011-11-09T21:43:00.000-08:00

If you are trying to integrate Symfony2 with Twitter, you're probably trying to install FOSTwitterBundle, and you may have faced two problems, one is that you can't create a user session after you login with Twitter and the other one is that there is no TwitterProvider class available as example in the instructions.

To help you with the second one here is a TwitterProvider class I made based on FacabookProvider.php

To solve the authentication problem on Symfony what I found is that Twitter anywhere only works at client level, so I decided to create a custom login button and built the authorization URL.

Controller action:

Twig template:

Then after the user authenticates with Twitter, the custom TwitterProvider can get the authentication tokens from the session and authenticate the user in Symfony.

Capifony: Send an email after deployment

2011-06-28T19:56:00.000-07:00

First, thanks to @cordoval at the #symfony channel for suggesting me to use a symfony2 command to do this.

To use this command you must have the SwiftmailerBundle enabled. More info here.

This is a simple Symfony2 command to send an email, you should add it to a "Command" directory inside your bundle and replace the namespace to fit your project bundle:

The email body is just "test" but you can probably modified it you need to.

Test the new command by running the following:

php app/console capifony:sendemail emailfrom@server.com emailto@server.com subject

Finally, this task will run the capifony:sendemail command after the deployment is complete, be sure to add it to your Capifony script:

How to enable the twig truncate filter (Text extension) in Symfony2 beta5

2011-06-19T08:23:00.000-07:00

Problem ?

In previous versions of Symfony2, to enable a extension you needed to add the Text and/or Debug extensions to an "extensions" array in your config.yml

//app/config/config.yml
# Twig Configuration
twig:
 debug:            %kernel.debug%
 strict_variables: %kernel.debug%
 extensions:
     - twig.extension.debug
     - twig.extension.text

This was because the extensions were added to the twig.xml file



//vendor/symfony/src/Symfony/Bundle/TwigBundle/Resources/config/twig.xml
...
  <service id="twig.extension.text" class="Twig_Extensions_Extension_Text" public="false">

     <service id="twig.extension.debug" class="Twig_Extensions_Extension_Debug" public="false">
...

But, this is the way to do it now :


// app/config/config.yml
...
services:
 twig.extension.text:
     class: Twig_Extensions_Extension_Text
     tags:
         - { name: twig.extension }

I spent some time trying to figure out how to do it, so I hope it helps someone.

Symfony2 + Twig pagination class

2011-05-23T21:38:00.000-07:00

I was looking for some pagination class to use with Symfony2, but most of the scripts that I found included html in the class, after some googling I found this post, and it was very helpful to get what I was looking for. I wanted something like the old digg pagination so I modified this class a little bit to get something like this:

The modifications I made:

- Show a range of pages around the current page as in the old digg.
- Parameters can be passed in a route, so you get a nice URL.

This is the class after the modifications:

<?php
/**
* Class to paginate a list of items in a old digg style
*
* @author Darko Gole%u0161
* @author Carlos Mafla <gigo6000@hotmail.com>
* @www.inchoo.net
*/
namespace Paginator;

class Paginator {

//current displayed page
protected $currentpage;
//limit items on one page
protected $limit;
//total number of pages that will be generated
protected $numpages;
//total items loaded from database
protected $itemscount;
//starting item number to be shown on page
protected $offset;
//pages to show at left and right of current page
protected $mid_range;
//range initial page
protected $start_range;
//range end page
protected $end_range;


function __construct($itemscount, $currentpage = 1,$limit = 20,$mid_range = 7) {
   //set total items count from controller
   $this->itemscount = $itemscount;

   $this->currentpage = $currentpage;

   $this->limit = $limit;

   $this->mid_range= $mid_range;

   //Set defaults
   $this->setDefaults();

   //Calculate number of pages total
   $this->getInternalNumPages();
   //Calculate first shown item on current page
   $this->calculateOffset();


   $this->calculateRange();

}


private function calculateRange() {

        $this->start_range = $this->currentpage - floor($this->mid_range/2);
        $this->end_range = $this->currentpage   floor($this->mid_range/2);

        if($this->start_range <= 0)
        {
            $this->end_range  = abs($this->start_range) 1;
            $this->start_range = 1;
        }
        if($this->end_range > $this->numpages)
        {
            $this->start_range -= $this->end_range-$this->numpages;
            $this->end_range = $this->numpages;
        }
        $this->range = range($this->start_range,$this->end_range);


 }

private function setDefaults() {
   //If currentpage is set to null or is set to 0 or less
   //set it to default (1)
   if (($this->currentpage == null) || ($this->currentpage < 1)) {
       $this->currentpage = 1;
   }
   //if limit is set to null set it to default (20)
   if (($this->limit == null)) {
       $this->limit = 20;
       //if limit is any number less than 1 then set it to 0 for displaying
       //items without limit
   } else if ($this->limit < 1) {
       $this->limit = 0;
   }
}

public function getNumpages() {
   return $this->numpages;
}

private function getInternalNumPages() {
   //If limit is set to 0 or set to number bigger then total items count
   //display all in one page
   if (($this->limit < 1) || ($this->limit > $this->itemscount)) {
       $this->numpages = 1;
   } else {
       //Calculate rest numbers from dividing operation so we can add one
       //more page for this items
       $restItemsNum = $this->itemscount % $this->limit;
       //if rest items > 0 then add one more page else just divide items
       //by limit
       $restItemsNum > 0 ? $this->numpages = intval($this->itemscount / $this->limit)   1 : $this->numpages = intval($this->itemscount / $this->limit);
   }
}



private function calculateOffset() {
   //Calculet offset for items based on current page number
   $this->offset = ($this->currentpage - 1) * $this->limit;
}

public function getCurrentpage() {
   return $this->currentpage;
}

public function getCurrentUrl() {
   return $this->currentUrl;
}

   //For using from controller
public function getLimit() {
   return $this->limit;
}
//For using from controller
public function getOffset() {
   return $this->offset;
}

public function getRange()
{
   return $this->range;
}

public function getMidRange()
{
   return $this->mid_range;
}

}

And this is how you can implement it in the controller:

use Path\to\class\Paginator;

class ListController extends SiteController
{
/**
* @extra:Route("/{offset}", name="_items")
* @extra:Template()
*/
public function listAction( $offset = 1)
{
  $repository = new ListRepository();

  $limit = 20;
  $midrange = 7;

  $itemsCount = $repository->getListCount();


  $paginator = new Paginator($itemsCount, $offset , $limit, $midrange);

  $items = $repository->getList ($offset);

  .
  .
  .
  return array('items' => $items, 'paginator' => $paginator);
}
}

And this is an example of a twig template you can use:

<div class="paginator">
<ul>
   {% if paginator.currentpage != 1 %}
       <li> <a class="previous" href="{{ path('_items', {  'offset': paginator.currentpage-1 }) }}">Previous</a>

   {% endif %}
   {% for i in 1..paginator.numpages%}

   {% if paginator.range.0 > 2 and i == paginator.range.0 %}
         ...
   {% endif %}


     {%  if(i==1 or i==paginator.numpages or i in paginator.range) %}

       {% if i==paginator.currentpage %}
       <li><a class="active" href="{{ path('_items', {  'offset': i })}}">{{i}}</a></li>
       {% else %}
       <li><a href="{{ path('_items', {  'offset': i }) }}"> {{i}}</a></li>
       {% endif %}
     {% endif %}

    {% if paginator.range[paginator.midrange -1] < paginator.numpages -1 and i == paginator.range[paginator.midrange-1] %}
         ...
    {% endif %}

   {% endfor %}


       <li> <a class="next" href="{{ path('_items', {  'offset': paginator.currentpage 1 }) }}">Next</a>
</ul>
</div>

I'm sure there are many improvements to be made, but it may help someone to have an idea.

PHP 5.3.3 short tags problem when upgrading

2010-08-30T12:18:00.000-07:00

Recently after upgrading php to 5.3.3 I found a problem with short tags <?= and <? , it seems that you now must only use <?php as starting tag, and all my code with <?= was not processed by php.

Short tags looks nicer and cleaner but can be a problem for people using XML, find more info here:

http://wiki.php.net/rfc/shortags

Here is a useful command if you need to replace this tags in your old code:


grep -oiR '<?=' /path/to/dir | cut -d ":" -f 1 | xargs sed -i 's/<?=/<?php echo /g'

How to resize or scale a list of images on linux

2009-09-03T06:53:00.000-07:00

Here is a simple but powerful command when you got several images that you want to shrink:


mogrify -scale 50% *.jpg

This will reduce all the images by 50%

Or if you just want to reduce one image to 200x200 pixels for example:


convert -scale 200x200 image.jpg image_small.jpg

Installing Oracle OCI8 and PHP

2009-01-28T08:54:00.000-08:00

I will describe here the steps I needed to install oracle connectivity for php. It's supposed you have php installed, in my case
I had php 5.1.6 throught RPM:


# rpm -qa  | grep php
php-5.1.6-20.el5_2.1
php-adodb-4.81-1.el5.rf
php-pecl-mailparse-2.1.1-1.el5.rf
phpmyadmin-2.11.8.1-1.el5.rf
php-odbc-5.1.6-20.el5_2.1
php-pecl-fileinfo-1.0.4-1.el5.rf
php-cli-5.1.6-20.el5_2.1
php-pear-file-1.2.2-1.el5.rf
php-eaccelerator-5.1.6_0.9.5.2-4.el5.rf
php-pecl-memcache-2.1.2-1.el5.rf
php-pear-db-1.7.13-2.el5.rf
php-common-5.1.6-20.el5_2.1

Distro:


# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5 (Tikanga)

1. Download and install the Instant Client rpms from oracle which you can get here http://www.oracle.com/technology/tech/oci/instantclient/instantclient.html.

This are the two files needed in my case:


# rpm -ivh oracle-instantclient11.1-basic-11.1.0.7.0-1.x86_64.rpm

# rpm -ivh oracle-instantclient11.1-devel-11.1.0.7.0-1.x86_64.rpm

2. Compile and install the oci8 extension:

Make sure you have the proper packages to compile a script like: php-devel, gcc,etc.


# pear install pecl/oci8

I used pear install pecl/oci8 instead of pear install oci8 because for some reason the second one returns an out of memory error and ignores the memory limit variable (memory_limit = XX ) from the
php.ini file.

When asked about this:

Please provide the path to the ORACLE_HOME directory. Use 'instantclient,/path/to/instant/client/lib' if you're compiling with Oracle Instant Client : autodetect

If you have oracle installed in the same server just hit enter. If not (you just want to connect to another server) type:

instantclient and enter or the path to the oracle libraries e.g: /usr/lib/oracle/11.1/client64/lib/.

3. Finally, edit your php.ini file (/etc/php.ini) and add the extension=oci8.so in the Dynamic extensions section. Don't forget to restart apache so the changes take effect in apache.

Additional information can be found here: http://www.oracle.com/technology/pub/notes/technote_php_instant.html.

How to solve no sound in flash videos ( fedora )

2008-09-10T07:08:00.000-07:00

After installing flash-plugin-9.0.124.0-release.i386 rpm I just got the flash plugin in my firefox but didn't get any sound. Googling about it I found a solution that worked, you need to install libflashsupport rpm, restart firefox and that's it:

just type this:


yum install libflashsupport

I guess this may work in other red hat based distros.

Mplayer crashes using beryl compiz-fusion

2008-06-21T15:14:00.000-07:00

When you start to use compiz-fusion and all the fancy desktop effects you will notice a little problem, you can't watch videos!. There's a bug that crashes mplayer, totem and all your video players. Hopefully there's a workaround for mplayer (not sure how to solve the problem with totem).

1. Open mplayer.
2. Right click over the window.
3. Click on preferences.
4. Click on the Video tab .
5. Change the video driver from Xv to X11 and click Ok.

You may have to restart mplayer to see the changes.

Vista Blue Screen of Death: STOP: 0x0000008E

2008-06-18T19:17:00.000-07:00

The famous blue screen of death attacked me again (previous bsod), this time on Vista, on my Dell inspiron 1520. It's very annoying that you have to deal with this kind of errors on a laptop recently bought. This error started to display a few seconds after logging in to the user account and with no clear reason of what could be the trigger of the error.

The solution this time actually had nothing to do (directly) with Windows Vista but with the laptop BIOS, and the solution came from the dell support site support.dell.com, the error itself suggested to update the BIOS , but I don't pay too much attention to this general error messages. If you're having this same problem you could go and follow this check list from dell, the BIOS upgrade was the second suggestion for a BSOF error and this was the one that worked for me, the file to do this is in the "Drivers and Downloads" section and you can select between all the different models.

Subversion: MKCOL of '...' 405 Method Not Allowed

2008-06-18T09:17:00.000-07:00

I was messing with the .svn/entries file in one of my local working copy folders, also I rm -rf a folder and regenerated again (I'm using symfony admin generator) , long story, but the fact is that I think I screwed up something and started to get this error when trying to commit:

# svn commit -m "backend modifications"
Adding apps/backend/modules/comment
svn: Commit failed (details follow):
svn: MKCOL of '/projects/cms/!svn/wrk/5ca09002-f34f-0410-890e-9511925f86a5/trunk/apps/backend/modules/comment': 405 Method Not Allowed (http://svn.calipso.com.co)

After some googling, I found it could be some proxy problem, but I wasn't using a proxy. Later I found that this error could mean that
the directory already existed in the repository and couldn't be recreated again, so my next step was to delete the folder from the repository (svn del ...) and try to do a fresh commit after recreating the folder and files included in it, and this worked ;).

I hope this helps some lost soul out there.

Unable to write config cache for "config/config_handlers.yml"

2008-05-22T09:30:00.000-07:00

After upgrading to symfony version 1.0.16 from 1.0.8 I started to get this error:

Unable to write config cache for "config/config_handlers.yml"

I tried to chmod 777 the cache and it didn't work. The solution for me was to disable SELinux.

How to do that? edit your /etc/sysconfig/selinux file, and set SELINUX=disabled:


# This file controls the state of SELinux on the system.

Page redirection in php with header('Location...') : Blank page vs Working redirection

2008-02-21T06:36:00.000-08:00

This kind of errors are what make debugging sometimes a very frustrating part of the developement, if you're suffering a blank page when trying to make a header('Location..'), give this a try:

This is a good redirection:


header('Location: http://www.example.com/');
exit();
?>

And this is a wrong redirection:


header('Location : http://www.example.com/');
exit();
?>

Notice a space between 'Location' and ':' this makes the redirection not to work!!!!

Simple errors likes this consume a lot of time :( , hope helps someone else...

.htaccess: order not allowed here

2008-02-11T12:29:00.000-08:00

I was getting an 500 Internal Server Error when trying to access Drupal after installing it, when I checked the http error log it said : .htaccess: order not allowed here.

After adding this to the httpd.conf and restarted apache it worked:


< directory "/home/httpd/html/drupal" >
AllowOverride FileInfo Limit Options Indexes
< /directory >

change "/home/httpd/html/drupal" to wherever your document root is.

Apache Error: No space left on device

2008-02-08T13:30:00.000-08:00

Apache doesn't start and the error log contains:


[emerg] (28)No space left on device: Couldn't create accept lock
or
[crit] (28)No space left on device: mod_rewrite: could not create rewrite_log_lock Configuration Failed

After checking your disk it shows that you have plenty of space. The problem is that apache didn't shut down properly, and it's left myriads of semaphore-arrays left, owned by 'apache' user.

Run:


ipcs -s | grep apache

Removing these semaphores immediately should solve the problem and allow apache to start.


ipcs -s | grep apache | perl -e 'while () { @a=split(/\s+/); print `ipcrm sem $a[1]`}'

where 'apache' is the owner of the apache process, if that's not the name of the user on your server change it.

How to check running queries and stats in postgres ?

2008-02-08T13:07:00.000-08:00

You want to know what query is slowing the database or want to check what's going on with a query you
just run, well in mysql just need to type 'show processlist;', but in postgres you must enable two variables
to check this and other stats.

Edit your postgres.conf which should be on /var/lib/pgsql/data/postgresql.conf for *nix installations and add or change this:


stats_start_collector = true

This must be set to true for the statistics collector to be launched at all.


stats_command_string = true

This enables monitoring of the current command being executed by any server process. The statistics collector subprocess need not be running to enable this feature.

After restarting postgres the following query will show currently running queries


/etc/init.d/postgresql restart


psql -U postgres template1 -c "select * from pg_stat_activity"

only as user "postgres"

How to create a DSL connection on ubuntu

2007-12-03T18:07:00.000-08:00

If your router/modem is set in bridge mode and you need to dial to make a connection you must use pppoE (Point to Point Protocol Over Ethernet) it's similar to the usual modem dial-up connection, but the difference is that you use the network an not the land line to connect.

In ubuntu you can run a little script called:


# pppoeconf

Just accept the defaults an make sure you give the right username/password.

it will edit this file:


# cat /etc/ppp/peers/dsl-provider

# Minimalistic default options file for DSL/PPPoE connections

noipdefault
defaultroute
replacedefaultroute
hide-password
#lcp-echo-interval 30
#lcp-echo-failure 4
noauth
persist
#mtu 1492
usepeerdns
plugin rp-pppoe.so
nic-ath0
user "xxxxxxxxxxx"

Now to create a connection use:


# pon dsl-provider

Plugin rp-pppoe.so loaded.

"dsl-provider" is name I chose for the connection which is the default

And to stop a connection use:


# poff

To stop all processes:


# poff -a

You can check the log using this commmand:


# plog
pppd[3928] : pppd 2.4.4 started by root, uid 0

My Firefox Toolbars are blank !

2007-09-19T09:36:00.000-07:00

For some unknown reason my web developer and delicious firefox toobars disappeared, I could see the space where they used to be but no icons or anything was there. I tried with the view toolbars menu , checking and unchecking to hide and show them, but that didn't work. Finally I found the solution, firefox have an option called firefox safemode http://kb.mozillazine.org/Safe_mode which allows us to troubleshoot some problems (like this one), all you have to do is:

1. Close any running intance of firefox.
2. Type this command :


firefox -safe-mode

For more info for different OSs check here
3. Then check the box for "Reset toolbars and controls"

4. Click on "Make changes and restart"

That's it... your toolbar icons should appear again.
