    <p>I'm trying to use the <code>FileUpload</code> plugin (https://github.com/webtechnick/CakePHP-FileUpload-Plugin) in my CakePHP (1.3) app.</p> <p>I have two models: <code>PendingContract</code> and <code>PendingContractFile</code>. A <code>PendingContract</code> can have many <code>PendingContractFile</code> records. When saving a new <code>PendingContract</code>, I'd also like to save the uploaded <code>PendingContractFile</code>; however, my save method fails because <code>PendingContract</code> does not yet have an ID, and that is used as the foreign key in my <code>PendingContractFile</code>.</p> <p>For clarity, here are my models:</p> <pre><code>&lt;?php class PendingContract extends AppModel { var $name = 'PendingContract'; var $belongsTo = array( 'Supplier' ); var $hasMany = array( 'PendingContractFile' ); } class PendingContractFile extends AppModel { var $name = 'PendingContractFile'; var $belongsTo = array( 'PendingContract' =&gt; array( 'className' =&gt; 'PendingContract', 'foreignKey' =&gt; 'pending_contract_id' ), 'Author' =&gt; array( 'className' =&gt; 'User', 'foreignKey' =&gt; 'author_id' ) ); } </code></pre> <p>And here is my controller method where I'm saving my <code>PendingContract</code>:</p> <pre><code>&lt;?php class PendingContractsController extends AppController { function add() { if (!empty($this-&gt;data)) { if ($this-&gt;FileUpload-&gt;success) { $this-&gt;Session-&gt;setFlash('Pending contract successfully created.'); $this-&gt;redirect(array('action' =&gt; 'index')); } else { $this-&gt;Session-&gt;setFlash($this-&gt;FileUpload-&gt;showErrors()); } } } } </code></pre> <p>Currently the error I'm getting is:</p> <blockquote> <p>1452: Cannot add or update a child row: a foreign key constraint fails (pending_contract_files, CONSTRAINT pending_contract_files_ibfk_1 FOREIGN KEY (pending_contract_id) REFERENCES pending_contracts (id) ON DELETE CASCADE ON UPDATE CASCADE)</p> </blockquote> <p>How can I use the <code>FileUpload</code> plugin so that it attaches the uploaded file with my new <code>PendingContract</code> record?</p>

    1. COIt looks like the `insert` is failing because either the Author or the PendingContract record isn't being saved beforehand. Both of those foreign keys must be present when inserting; my guess is that one or both of them are missing.

    2. CO@inkedmn I've identified the problem. I just wondered if any one has had the same problem and if so, what solution they arrived at.

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.
