Only one table's datas selected when join two tables in cakephp

问题

I used this code, but only one table's data selected.

I need to select all fields from two tables:

$options['joins'] = array(
                array('table' => 'tbl_users',
                    'alias' => 'Users',
                    'type' => 'INNER',
                    'foreignKey' => 'assigned_by',
                    'fields' => 'Users.user',
                    'conditions' => array(
                        'TravancoAdmin.assigned_by = Users.id'
                    )
                )
            );
            $options['conditions'] = array( 'TravancoAdmin.id' => $task_id);
$result = $this->find('all', $options);
        return $result ? $result : 1;

How can i get all fields from two tables?

If there is any mistakes in my code?

You need to move the 'fields' option out of 'joins'. Otherwise $this->find will only fetch the fields for the current model. Remember to add all fields you need when you specify 'fields', both the ones for the current model and the ones you need from the table you're joining.

For example:

$options['joins'] = array(
                array('table' => 'tbl_users',
                    'alias' => 'Users',
                    'type' => 'INNER',
                    'foreignKey' => 'assigned_by',
                    // 'fields' => 'Users.user', <- get rid of this
                    'conditions' => array(
                        'TravancoAdmin.assigned_by = Users.id'
                    )
                )
            );
$options['fields'] = array('TheModelThatThisRefersTo.*','Users.user'); // <- insert this
$options['conditions'] = array( 'TravancoAdmin.id' => $task_id);
$result = $this->find('all', $options);
return $result ? $result : 1;

Try to use reucrsive 2 and you have to relation the table into your moedl correctly if you want to retrieve your data. After you the query you can have a big array with all fields, try to print with a var_dump to see if you have all your fields that you want

$this->recursive = 2;
$options['joins'] = array(
                array('table' => 'tbl_users',
                    'alias' => 'Users',
                    'type' => 'INNER',
                    'foreignKey' => 'assigned_by',
                    'fields' => 'Users.user',
                    'conditions' => array(
                        'TravancoAdmin.assigned_by = Users.id'
                    )
                )
            );
            $options['conditions'] = array( 'TravancoAdmin.id' => $task_id);
$result = $this->find('all', $options);
        return $result ? $result : 1;
