    <p>In SilverStripe usually the 3rd argument to a FormField is the value, so for example a TextField has the following arguments:</p> <pre><code>new TextField($name = 'myField', $title = 'Please write something in my Field', $value = "yay"); </code></pre> <p>but this would not work in the CMS (at least in SilverStripe 2 if you are using a Page, not sure on DataObject) because SilverStripe overwrites all values when it tries to populate the Form with the values of the current object</p> <p>so you have several alternatives, the 2 easiest alternatives are:</p> <pre><code>class MyContentObject extends DataObject { public static $db = array( 'Text' =&gt; 'HTMLText', ); public static $has_one = array( 'Member' =&gt; 'Member', ) public function getCMSFields() { $fields = new FieldSet(); $fields-&gt;push(new Textarea('Text', 'Text')); if (!$this-&gt;MemberID) $this-&gt;MemberID = Member::currentUserID(); $fields-&gt;push(new HiddenField('MemberID')); return $fields; } } </code></pre> <p>And 2nd option, which is way better in this case, you don't even need a hidden field, you can just set the MemberID right before the record gets written to database by using onBeforeWrite:</p> <pre><code>class MyContentObject extends DataObject { public static $db = array( 'Text' =&gt; 'HTMLText', ); public static $has_one = array( 'Member' =&gt; 'Member', ) public function getCMSFields() { $fields = new FieldSet(); $fields-&gt;push(new Textarea('Text', 'Text')); return $fields; } public function onBeforeWrite() { // this method will be called every time the object gets saved parent::onBeforeWrite(); if (!$this-&gt;MemberID) $this-&gt;MemberID = Member::currentUserID(); } } </code></pre>

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
