I’m tired to rewrite everytime “./symfony …”, really, I do it a lot of times! So I optimized it, let’s go. First you need to do a alias to symfony, to execute ./symfony from any directory.

Create a file /usr/local/bin/sf

while [ 1 ]; do
    if [ -f 'symfony' ]; then

        ./symfony $*
        exit $?
    fi

    cd ..
    if [ "$PWD" = "/" ]; then

        echo ‘cannot find symfony project directory’
        exit 1

    fi
done

There are some snippet liek it on symfony-project.com, but I’ve changed a little to run here.

After, you can work with alias as you want. I created the following option:

alias sf-restart='sf doctrine:build-all-load --no-confirmation; sf cc '

So, you can use the sf-restart to use less lines in your job.

The pattern to create alias is following.

at prompt use:
alias cds='cd /etc/rc.d/init.d ; ls'

explaining: alias name='comand ; comand2 ; comand3'

I’m really enjoying to develop with symfony. I’m working a lot and studying very hard on my free time to be on the time with news. Of course on my job the most important thing is to be the best, I can’t do other thing. If I pause four hours to sleep, someone will be studying to be better than me.

Work with symfony is amazing, I love when I think “Wow! I did it in only one hour? Two months ago I was spending three or more hours.” That’s because symfony have magic! =)

You can utilize the magic findBy*() and findOneBy*() methods to find records by single fields value.

$user = Doctrine::getTable(‘User’)->findOneByUsername(‘jwage’);
$users = Doctrine::getTable(‘User’)->findByIsActive(1);

It’s magic, isn’t?

Validation in symfony is pretty easy. Butttt, sometimes we need to create some “custom” function. Let’s talk about it today.

I’m working at a lovelly project. My client give me freedom to develop. That’s good, but a big responsability too. I’m working hard to do the best that I can do. A good development, object oriented, and when I see something that I would do better I go back and do again, better!

That’s the way with credit card validation. I get a excelent class created by John Garden, on the far away year of 2005. I customized it, changed somethings, and I’m using it with symfony. Automagically works good, and it’s in portugues and english.

First, at SomethingForm.class.php I do two little things

At function configure(), I put

// add a post validator
$this->validatorSchema->setPostValidator(
new sfValidatorCallback(array('callback' => array($this, 'checkCreditCard')))
);

And above, the function checkCreditCard():

    public function checkCreditCard($validator, $values)
    {
        if ($values['numero'])
        {
            $oCreditCard = new myCreditCardValidator($values);
            $sError = $oCreditCard->execute($values['tipo'], $values['numero'], ‘pt_BR’);

            if ($sError != 1){
                // Create the error object
                $sfError = new sfValidatorError($validator, $sError);
                // throw an error bound to the number field
                throw new sfValidatorErrorSchema($validator, array(’numero’ => $sfError));
            }
        }
        return $values;
    }

The class, is above.

I often forget how to set default values for form fields. Mainly because it’s a function of sfForm rather than sfFormField I think. In the snippet below ‘field’ you are setting the default value for, and $value should be the default value.

<?
// lib/form/MyModelForm.class.php
public function configure() {
$this->setDefault('field', $value);
}
?>


A Note on Snippets: When using frameworks such as Symfony it is often the simplest pieces of code which are the hardest to either find or remember. These snippets are placed here for my own reference and will hopefully be useful to others. If you find them useful or have any suggestions, please let me know.

Are you missing me?

Well, 2009 started very good, but I got a big problem on june starts that was really hard to be good.

But, I spent only 40 minutes crying, and one week after, I was already working and with news contracts. Big projects and good partners that I hope (and need), be with me more than two months.

I want say thank you to everyone who give some good work, and of course, to everyone who contracted my job or from my company Lado Direito Soluções.

I’ll write only the name, without family name, but they will know where they are.

Thank you, Joana, Ana, Tony, Madalena, Francisco, Rafael, Cesar, Lorena, Felipe, Thaissa and the others that maybe I forgot. Here we go again!

The next six months will be better than the previous.

It’s a Symfony thing in sfDateFormat::getPattern().

You can use this helper like this following example:

<?php echo format_date($blog_post->getCreatedAt(), "D“) ?>

The D is a pre-formatting from symfony, above a list about others pre formats options.

switch ($pattern)
    {
      case 'd':
        return $this->formatInfo->ShortDatePattern;
        break;
      case 'D':
        return $this->formatInfo->LongDatePattern;
        break;
      case 'p':
        return $this->formatInfo->MediumDatePattern;
        break;
      case 'P':
        return $this->formatInfo->FullDatePattern;
        break;
      case 't':
        return $this->formatInfo->ShortTimePattern;
        break;
      case 'T':
        return $this->formatInfo->LongTimePattern;
        break;
      case 'q':
        return $this->formatInfo->MediumTimePattern;
        break;
      case 'Q':
        return $this->formatInfo->FullTimePattern;
        break;
      case 'f':
        return $this->formatInfo->formatDateTime($this->formatInfo->LongDatePattern, $this->formatInfo->ShortTimePattern);
        break;
      case 'F':
        return $this->formatInfo->formatDateTime($this->formatInfo->LongDatePattern, $this->formatInfo->LongTimePattern);
        break;
      case 'g':
        return $this->formatInfo->formatDateTime($this->formatInfo->ShortDatePattern, $this->formatInfo->ShortTimePattern);
        break;
      case 'G':
        return $this->formatInfo->formatDateTime($this->formatInfo->ShortDatePattern, $this->formatInfo->LongTimePattern);
        break;
      case 'i':
        return 'yyyy-MM-dd';
        break;
      case 'I':
        return 'yyyy-MM-dd HH:mm:ss';
        break;
      case 'M':
      case 'm':
        return 'MMMM dd';
        break;
      case 'R':
      case 'r':
        return 'EEE, dd MMM yyyy HH:mm:ss';
        break;
      case 's':
        return 'yyyy-MM-ddTHH:mm:ss';
        break;
      case 'u':
        return 'yyyy-MM-dd HH:mm:ss z';
        break;
      case 'U':
        return 'EEEE dd MMMM yyyy HH:mm:ss';
        break;
      case 'Y':
      case 'y':
        return 'yyyy MMMM';
        break;
      default :
        return $pattern;
    }

That’s really good to don’t lose time.

After get some problems with Subversion at “command-line” in linux I decided to use the Zend Studio plugin. Very easy, until Windows Vista fuck me.

Well, after some time studying, and NOT FOUNDING anything on internet searches, I’ll be a good guy and put here the solution if you are getting problems with Zend Studio with Subversion in Windows Vista, OPEN THE ZEND STUDIO as Adminitrator.

What is the problem that I get?

svn: Can’t determine the system config path

Now, you can enjoy your friday, using this plugin!

I’m really busy. I have a BIG TODO list, many things to study, and less time. Well, you can include some clients that not had paid me (normal here, NORMAL!?! well, that’s comum, person that use and not pay, it’s boring, time doesn’t is money always, sometimes your time is trash to some people). One month without surf, sixmonths without soccer, really this last weeks was being hard.

Time? Watch Lost? Study english? Nope, only work, work, work…

I promise, as soon as the things be more “normal” I’ll post some good things about Symfony, I’m learning a lot and I can say, Symfony x Cakephp?!? Well, symfony of course, and as I’m not fan of Rails, I like more and more Symfony.

I hope you like the new layout, downloaded and instaled in five minutes, as well the new option, to see my website in english, spanish, and of course Portuguese.
