It is a very\u00a0 steep learning curve, and I keep forgetting what I learn, so just going to keep a list.<\/p>\n

  1. To make a link to ‘id’ on a .ctp page link to something more useful change the column name thus:\n
    echo $this->Html->link($powerpoint['User']['id'], array('controller' => 'users', 'action' => 'view', $powerpoint['User']['id'])); \r\n\r\n\/\/becomes\r\n\r\necho $this->Html->link($powerpoint['User']['username'], array('controller' => 'users', 'action' => 'view', $powerpoint['User']['id']));<\/pre>\n
    (The query is doing a join automatically in the background)<\/li>\n
  2. To make a droplist show a useful thing like the name rather than the key, you need to go in to the XxxxxxController and change the function thus:\n
    $users = $this->Powerpoint->User->find('list');\r\n\r\n\/\/becomes\r\n\r\n$users = $this->Powerpoint->User->find('list',array('fields' => array('User.id', 'User.username')));<\/pre>\n
    I guess it then used the two fields as given.\u00a0 If you add a third field it is used as a label in the option.\u00a0 Not sure how to concatenate the columns if you want “Firstname Lastname” in the droplist.<\/li>\n
  3. The Model reflects the database. I knew that but recording it here, as I actually used it.<\/li>\n
  4. If you have a table that is joined through another table (belongsto > belongsto) then you can make it appear thus in the Controller:\n
    \t\t$users = $this->Question->Powerpoint->find('list', array(\r\n\t\t\t\t\"fields\" => array('Powerpoint.user_id', 'Users.username'),\r\n\t\t\t\t\"joins\" => array(\r\n\t\t\t\t\tarray(\r\n\t\t\t\t\t\t\"table\" => \"Users\",\r\n\t\t\t\t\t\t\"type\" => \"LEFT\",\r\n\t\t\t\t\t\t\"conditions\" => array(\r\n\t\t\t\t\t\t\t\"Powerpoint.user_id = users.id\"\r\n\t\t\t\t\t\t)\r\n\t\t\t\t\t)\r\n\t\t\t\t)\r\n\t\t\t));<\/pre>\n
