Fix ‘dbModel Read Resource Does Not Implement Zend_Db_Adapter_Abstract’ Error

databaseerror

I put my magento project on a linux server. First the error log messages shown up, but the folder var was missed. Then I created the var folder, I give it the 777 permissions and same with cache, report,session. In the error file from the report folder I got this message:

So what could cause this problem ? WHY ? and I do I solve it ?

After I put the right database connection I also changed this line:

<disable_local_modules>false</disable_local_modules>

into this

<disable_local_modules>true</disable_local_modules>

I gave recursively the 777 permission to the var folder using this command:

chmod -R 777 var

Magento – getting Error in magento

Check for anything in all files, before the starting <?php and if the file ends with an ?>. Remove the trailing ?>. No one needs this.

This error is often raised, because you added a space before the stating <?php

And I think in later PHP versions, they improved the error by adding the information where the output started. Think about updating php to know this.

Magento 1.7 – Fix Currency ‘USD’ Not Found Error

Ok so I am not sure if this is the bug but if you compare the Magento 1.8 and Magento 1.7 versions of the function currency in Mage_Core_Model_Local you will notice a reference to a bug with Zend_Currency

Magento 1.7: Mage_Core_Model_Local->currency

/**
 * Create Zend_Currency object for current locale
 *
 * @param   string $currency
 * @return  Zend_Currency
 */
public function currency($currency)
{
    Varien_Profiler::start('locale/currency');
    if (!isset(self::$_currencyCache[$this->getLocaleCode()][$currency])) {
        try {
            $currencyObject = new Zend_Currency($currency, $this->getLocale());
        } catch (Exception $e) {
            $currencyObject = new Zend_Currency($this->getCurrency(), $this->getLocale());
            $options = array(
                    'name'      => $currency,
                    'currency'  => $currency,
                    'symbol'    => $currency
            );
            $currencyObject->setFormat($options);
        }

        self::$_currencyCache[$this->getLocaleCode()][$currency] = $currencyObject;
    }
    Varien_Profiler::stop('locale/currency');
    return self::$_currencyCache[$this->getLocaleCode()][$currency];
}

Magento 1.8: Mage_Core_Model_Local->currency

/**
 * Create Zend_Currency object for current locale
 *
 * @param   string $currency
 * @return  Zend_Currency
 */
public function currency($currency)
{
    Varien_Profiler::start('locale/currency');
    if (!isset(self::$_currencyCache[$this->getLocaleCode()][$currency])) {
        $options = array();
        try {
            $currencyObject = new Zend_Currency($currency, $this->getLocale());
        } catch (Exception $e) {
            /**
             * catch specific exceptions like "Currency 'USD' not found"
             * - back end falls with specific locals as Malaysia and etc.
             *
             * as we can see from Zend framework ticket
             * http://framework.zend.com/issues/browse/ZF-10038
             * zend team is not going to change it behaviour in the near time
             */
            $currencyObject = new Zend_Currency($currency);
            $options['name'] = $currency;
            $options['currency'] = $currency;
            $options['symbol'] = $currency;
        }

        $options = new Varien_Object($options);
        Mage::dispatchEvent('currency_display_options_forming', array(
            'currency_options' => $options,
            'base_code' => $currency
        ));

        $currencyObject->setFormat($options->toArray());
        self::$_currencyCache[$this->getLocaleCode()][$currency] = $currencyObject;
    }
    Varien_Profiler::stop('locale/currency');
    return self::$_currencyCache[$this->getLocaleCode()][$currency];
}

My suggestion would be to try updating the try catch to match that of Magento 1.8 (I know this is not the best solution and obviously I would not suggest editing the core files but adding a rewrite)
