    <p>Well, Grails uses a MVC pattern and therefore you should not directly change a domain class property within a GSP page.</p> <p>Of course you can use the JQuery date picker but you should provide a controller action to update your domain class property</p> <pre><code>def updateDateUsingAjax() { def domain = MyDomain.load(params.id) /* Lets pretend the content of params.date has the format MM/dd/yyyy You can use Date.parse method of the Groovy JDK to create a java.util.Date instance of a String. http://groovy.codehaus.org/groovy-jdk/java/util/Date.html#parse(java.lang.String, java.lang.String) */ domain.myDate = Date.parse('MM/dd/yyyy', params.date) domain.save() } </code></pre> <p>Now all you have to write is an Ajax call to this controller action and you successfully separated the presentation layer from the rest of your application.</p> <p>And here is how your GSP could look like.</p> <pre><code>&lt;!doctype html&gt; &lt;html&gt; &lt;head&gt; &lt;meta name="layout" content="main"/&gt; &lt;title&gt;Welcome to Grails&lt;/title&gt; &lt;r:require module="jquery-ui"/&gt; &lt;/head&gt; &lt;body&gt; &lt;div&gt; &lt;g:formRemote name="myForm" url="[controller: 'standard', action: 'updateDateUsingAjax']" onSuccess="showDialog()"&gt; &lt;p&gt;Your date: &lt;g:textField name="pick"/&gt; &lt;/p&gt; &lt;p&gt;&lt;g:hiddenField name="id" value="your id"/&gt;&lt;/p&gt; &lt;input type="submit" value="Delete Book!" /&gt; &lt;/g:formRemote&gt; &lt;/div&gt; &lt;div id="dialog" title="Success" style="display:none;"&gt; &lt;p&gt;You have successfully updated your date&lt;/p&gt; &lt;/div&gt; &lt;script type="text/javascript"&gt; $(document).ready(function() { $("#pick").datepicker({dateFormat: 'yy/mm/dd'}); }) function showDialog() { $("#dialog").dialog(); } &lt;/script&gt; &lt;/body&gt; </code></pre> <p></p>

    1. COSo how would I pass a "new Date()" to this controller call. Because even without ajax, I could just called the controller method with teh following syntax: ${updateDateUsingAjax()} Right? But the thing is, how do I pass a new date to that? I'm a tad lost, I see your idea and it seems genius but I'm missing a few details. Because right now all I can do is use the built in <g:datePicker /> tag. Thank you for your idea, I just would like to understand it more.

    3. COOk, thank you so much, because I'm super lost. In fact, now I have no idea how to really call a controller in gsp. All our stuff had scaffolding set to true, then we deleted that, and everything was kind of created automatically. I'm trying to read through the documentation and it's just not making sense how to do this kind of stuff.

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.
