    <p>I have two models: <code>Fight</code> and <code>Fighter</code>. My <code>Fight</code> model has two <code>belongsTo</code> relationships:</p> <pre><code>&lt;?php class Fight extends AppModel { public $belongsTo = array( 'FighterA' =&gt; array( 'className' =&gt; 'Fighter', 'joinTable' =&gt; 'fighters', 'foreignKey' =&gt; 'fighter_a_id' ), 'FighterB' =&gt; array( 'className' =&gt; 'Fighter', 'joinTable' =&gt; 'fighters', 'foreignKey' =&gt; 'fighter_b_id' ) ); } </code></pre> <p>This is so I can set two fighters that participate in a fight. However, I’m having difficulty working out how to set the other side of the relationship, in my <code>Fighter</code> model.</p> <p>I know I want to find all fights where either the <code>fighter_a_id</code> or <code>fighter_b_id</code> column equals the fighter ID, but having trouble translating this to a relationship in my model.</p> <p>I’ve tried:</p> <pre><code>&lt;?php class Fighter extends AppModel { public $hasMany = array( 'Fight' =&gt; array( 'conditions' =&gt; array( 'OR' =&gt; array( 'Fight.fighter_a_id' =&gt; 'Fighter.id', 'Fight.fighter_b_id' =&gt; 'Fighter.id' ) ) ) ); } </code></pre> <p>But CakePHP throws an error, where it is still trying to query the (non-existent) <code>fighter_id</code> it’s automatically generating, combining the generated <code>WHERE</code> clause with the <code>OR</code> clause I‘ve specified above.</p> <blockquote> <p>Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'Fight.fighter_id' in 'field list'</p> </blockquote> <p>And the generated SQL statement:</p> <blockquote> <p><code>SELECT Fight.id, Fight.fighter_a_id, Fight.fighter_b_id, Fight.event_id, Fight.weight_division_id, Fight.rounds, Fight.rounds_length, Fight.winner, Fight.winning_round, Fight.winning_time, Fight.win_method, Fight.fighter_id FROM fights AS Fight WHERE ((Fight.fighter_a_id = 'Fighter.id') OR (Fight.fighter_b_id = 'Fighter.id')) AND Fight.fighter_id = (1)</code></p> </blockquote> <p>When finding records from the <code>fighters</code> table, I’d like to also list related <code>Fight</code> models (in chronological order, but that’s handled in another column left out as it’s unrelated to this issue).</p>

    1. COYour setup is incorrect. You should be using HABTM (hasAndBelongsToMany) to join your Fighters to their Fights. Then you can store the extra data in the join table.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
