    <p>Let's say we have a person object with a few "person-properties"</p> <pre><code>personModel = { membership-number : "abcd", name : "Anonymous", dob : "14/04/2009", avatar : "image.png" } </code></pre> <p>Let's also say we have metadata about these "person-properties".</p> <pre><code>meta-data = { membership-number: {data-type : "string", editable : "false"}, name : {data-type : "string", editable : "true"}, dob : {data-type : "date", editable : "true"}, avatar : {data-type : "image", editable : "true"} } </code></pre> <p>Now I would like to list these properties of the personModel on a page with the following constraints. member-ship name which is string and non-editable, should be displayed as a label. All editable strings as text box, all date types with a date-picker, etc.</p> <p>I know this can be done with angular directives. Have a directive called person which will iterate through the "person-properties" of the personObject.</p> <pre><code>&lt;person ng-model={{personModel}}&gt; &lt;/person&gt; </code></pre> <p>and have a directive for each "person-property" inside the person, like : </p> <pre><code>&lt;person-property ng-repeat = {{prop in person-properties}}&gt; &lt;/person-property&gt; </code></pre> <p>Let's also assume that the property directive has access to the metadata. To get templates based on the property-type, I can write if-else in the person-property's definition to choose which template to return, like this skeleton.</p> <pre><code>if(property_type === "date"){ template = "&lt;datepicker&gt; &lt;/datepicker&gt;" } else if (property-type === "numeric"){ template = "&lt;numeric-editable-box&gt; &lt;/numeric-editable-box&gt;" } </code></pre> <p>But is there a more elegant way to do this?</p> <p>WPF has something called TemplateSelector to do this. Does angular have something similar that I am unaware of?</p>

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.
