Fatal error: Uncaught exception 'Zend_Db_Exception' with message 'Adapter name must be specified in a string'

I've been googling this problem but can't find any hints to follow.  Can somebody help me fix this Error?
The code that is causing this error is this:


Bootstrap

    protected function _initRegDatabase()
    {
    $config = Zend_Registry::get('config');
       
        $db = Zend_Db::factory($config->db);                            //   This line seems to cause the Error!
        Zend_Db_Table_Abstract::setDefaultAdapter($db);
        Zend_Registry::set('db', $db);
    }

apprentice,

What is the var dump output on $config->db? Check the format of it against the proper format listed in the reference manual(http://framework.zend.com/manual/en/zend.db.html#zend.db.adapter.connecting.factory-config). 

Regards,

Duo

1.) Howto var dump?
Hi Duo could you teach me how to do the var dump thing correctly?  I'm a PHP newbie, every view page gives me that Fatal error message.  I don't know how to force a var dump into an Error view page.  I tried to put the "Zend_Debug::dump();" into Bootstrap but nothing new happens.

View page - Fatal error

Bootstrap - Zend_Debug::dump()

2.) The story
My web application is 99% based on Akrabats tutorial in case this information helps.
http://akrabat.com/zend-framework-tutorial/

The Akrabat Bootstrap file looks like this.  And _initAutoload() function usually starts up the config.ini file and database connection.
http://pastebin.com/m3e88b3f6

application/configs/application.ini
http://pastebin.com/m4c2fd8a3


So my _initRegDatabase() function seems redundant.  Do you think that I need to set the config and database into registry by working within _initAutoload() function instead?  By using the Zend_Application_Module_Autoloader somehow some way?

I made the changes at pastebin, but I copied the relevant part below again for you here:

Inside _initRegDatabase

$this->bootstrap('RegConfig'); $config = Zend_Registry::get('config'); Zend_Debug::dump($config->db); exit;

Try this and you should see some kind of output. Let me know if that helps.

Hi Duo your pastebin edits didn't seem to have been updated.  Next time try and create a new pastebin link instead. 
Fortunately you wrote the relevant code in the email so I was still able to follow your lead.

Hi Mert thanks for the alternate approach.

Bootstrap - Mert approach

- "print_r ..." gives me a white blank screen. 
- While "echo print_r ..." returns the number 1.



Bootstrap - Duo approach
http://pastebin.com/m6b634ceb

- The browser only returns "NULL" on the screen.  Are both of these results a bad or a good sign?
____________________________________________________


The Akrabat tutorial I've been following uses this ErrorController maybe I have to force the var_dumps in there?
In case your approaches didn't solve the problem already.

Actually your config file for the db is

resources.db.adapter = "PDO_MYSQL" resources.db.params.host = "localhost" resources.db.params.username = "zfia" resources.db.params.password = "zfia" resources.db.params.dbname = "batman" resources.db.params.profiler = "true"

This is probably why $config->db is null as your config is setup for the "Db Resource Adapter." Take a look at: http://framework.zend.com/manual/en/zend.application.available-resources.html#zend.application.available-resources.db

For a quick start you can try this:

protected function _initRegDatabase() {

$resource = $bootstrap->getPluginResource('db'); $db = $resource->getDbAdapter();

var_dump($db); exit;

Zend_Db_Table_Abstract::setDefaultAdapter($db);

Zend_Registry::set('db', $db);

}

You should get a massive output from var_dump($db); if it is working. If it is you can remove the var_dump line, but again read the reference manual linked above to understand "why".

Regards,

Duo

Thanks Duo for the pointers I finally managed to make some sense out of that Zend manual :-P
Reading that manual is like 99% theoretical mumbo jumbo and 1% practical examples.


Solution

1.         protected function _initRegDatabase()
2.         {
3. //_________

5. //   DUO

7.  
8. /*
9. $resource = $bootstrap->getPluginResource('db');
10. $db = $resource->getDbAdapter();
11. var_dump($db); exit;
12. */
13.  
14. $this->bootstrap('db');
15. $resourceDb = $this->getResource('db');
16. //var_dump($resourceDb); exit;
17.  
18. Zend_Db_Table_Abstract::setDefaultAdapter($resourceDb);
