Newbie - Day 2: 500 Internal Server error after click Create

[binro01]

Hi all,

Almost finished with day 2, and I have been able to generate the CRUD files and navigate to http://virthost/question URL, but when I click the Create link (http://symfony/question/create) I get a 500 Internal server error...

Not much other info on the error was given to me.

I did do a symfony cc to to attempt to clear the cache.

Any help to fully test my CRUD scaffold would be much appreciated

I'm running Symfony on top of my WAMP v2.0 stack

Thanks in advance

Rob

some more info:

when I navigate to http://symfony/frontend_dev.php/question/create I get the following error:

symfony v.1.1.1 - php 5.2.5
for help resolving this issue, please visit http://www.symfony-project.org/.

[halfer]

You are running symfony 1.1.x, but Askeet only (presently) works in 1.0 - sorry! There has been some discussion that this should have been updated for 1.1, but as ever with open source projects, it's a matter of how much time people have to donate to the project.

If you are happy to learn 1.0, Askeet is a good way to go. However if you want to learn 1.1 (I've not really done anything with it, but the Forms stuff looks excellent) then you would be better off with other tutorials. The material at thatsquality.com would be a good start, or do a web search.

[cloud]

Well I went to the http://www.thatsquality.com/ but it seems that even that guy is having trouble to keep up with it. so any suggestions where one could learn 1.1 version

[halfer]

The stuff there is still very relevant, it's just he was working with a beta version. However do try My First Project, which is nearly completed (I've got a bit more to finish on it, but it's 95% of the way there and useful already, in my opinion):

http://www.symfony-project.org/tutorial/1_1/my-first-project

[danwwilson]

Rob,

From what I can gather (I only solved this one tonight too) you need to create a __toString() function in your user class. I had a look at Halfer's tutorial to get an idea of this.

In your /lib/model/User.php file you need to insert the following code:

Code: Select all

public function __toString()
{
  return $this->getTitle();
}

In the end the total contents of your User.php file should look like this:

Code: Select all

<?php

/**
 * Subclass for representing a row from the 'ask_user' table.
 *
 *
 *
 * @package lib.model
 */
class User extends BaseUser
{
  public function __toString()
  {
    return $this->getTitle();
  }
}

If this works please respond so that other users can get the benefits too.

[muzykagra]

Yes, this solution works, thanks.
BTW someone should add this to tutorial to version v.1.1 ;]

Many people can get bored with symfony when something from tutorial get wrong.

[halfer]

BTW someone should add this to tutorial to version v.1.1 ;]

Yes, I agree; it would be nice. I've just made a whole bunch of changes to the tutorial for 1.1, and I don't have time to re-do Askeet as well (which is a much larger project). Askeet is OK I think, so long as you're willing to do some digging/asking in the forums (if this puts you off, then symfony may have too steep a learning curve for you anyway). That said, I still agree it would be nice to have a more polished version.

Maybe a symfony developer off work with seasonal 'flu could spend some time on Askeet? ~ ~

[kluch]

OMG tnx this help a fcuking lot ~ ~
