    <p>I want to combine the form binding from play 2.0 framework with a class extending Record from the circumflex-orm (<a href="http://circumflex.ru/projects/orm/index.html" rel="nofollow">website</a>).</p> <p>These are my class objects:</p> <pre><code>class Task extends Record[Long, Task] with IdentityGenerator[Long, Task] { def this(name: String, description: String) = { this() this.name := name this.description := description } val id = "id".BIGINT.NOT_NULL.AUTO_INCREMENT val name = "name".VARCHAR(255).NOT_NULL val description = "description".TEXT.NOT_NULL def PRIMARY_KEY = id def relation = Task } </code></pre> <p>And this is what i try to do with the play form:</p> <pre><code>val taskForm: Form[Tasks] = Form( mapping( "name" -&gt; text, "description" -&gt; text ) {(name, description) =&gt; Task(name, description)} {(t: Task) =&gt; Option(t.name(), t.description()) } ) </code></pre> <p>But i get an error like this:</p> <pre><code>found : models.Task =&gt; Option[(String, String)] required: Unit =&gt; Option[(String, String)] {(t: Task) =&gt; Option(t.name(), t.description())} </code></pre> <p>And if i replace Option by Some:</p> <pre><code>found : models.Task =&gt; Some[(String, String)] required: Unit =&gt; Option[(String, String)] {(t: Task) =&gt; Some(t.name(), t.description())} </code></pre> <p>I am clueless right now and any hint would be appreciated.</p> <p>Thanks a lot.</p> <p><strong>EDIT:</strong> I made a basic error, i did name the Form: </p> <pre><code>val taskForm: Form[Tasks] = Form( </code></pre> <p>when the name of the class is "Task". So i can change it to:</p> <pre><code>val taskForm: Form[Task] = Form( mapping( "name" -&gt; text, "description" -&gt; text ) ( (name, description) =&gt; Task ) ( (t: Task) =&gt; Option() ) ) </code></pre> <p>And now i get a different error:</p> <pre><code>Unspecified value parameter x ( (t: Task) =&gt; Option() ) </code></pre> <p>I made a simple project with the needed dependencies in eclipse, you can download it here and look at it, if it helps: <a href="http://sveri.de/files/public-docs/sonstiges/FormBindOrmExample.zip" rel="nofollow">Basic Form Example</a></p>

    1. COI think `() => Some(t.name(), t.description())` should help

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.
