Question

I have a problem with relationships in the Doctrine. Works on Mysql database. The problem occurs when downloading data using the relationship throws me this error: Doctrine_Table_Exception: Unknown relation alias Model_Training

Please help me get tired of it some days I sit on it and nothing came up, and google also did not find anything.

Here is the code that retrieves data:

$dataRows = Doctrine_Query::create()
                    ->from('Model_Training a')->where('a.idTrainings = ?', $this->_getParam('id'))
                    ->leftJoin('a.Model_TrainingBonuse ac')
                    ->leftJoin('a.Model_Bonuse ad')
                    ->fetchArray();

Schema.yml file with the formation of models for the Doctrine:

Answer 1

There’s no “Model_Training” table definition in your schema.yml file…theres “Training” though… If there’s no “alias class” or “foreign alias” element specified in your schema.yml, table definition’s name is used. So instead of “Model_Training” use “Training” (this applies to “Model_Bonuses” and others too).
