Hi,

I want to assing a special css class to an input field when the according field in the bean is required.

I have a domain class like this

class Dummy
{
String iAmRequired
static constraints = {
iAmRequired(nullable: false) }
}

and a create.gsp where I assign values to this class like this

<input type="text" name="iAmRequired" >${fieldValue(bean:dummy, field:'iAmRequired')}</input>

Is there something like class="value ${hasErrors(bean:dummy,field:'iAmRequired','errors')}" with what I can do it?

Hi!

Maybe you can try something like this in your Controller to find out dynamically which properties have a blank constraint applied.
Collect the keys that have the constraint you want to check.



In the view you could probably use a nifty prototype script that adds some css class or style to your input fields.

BTW: http://jira.codehaus.org/browse/GRAILS-270 is what you need I think. Be patient and stay tuned

I'm also quite new to Grails and maybe someone here knows a much more elegant solution.

kind regards,

Hi!

Maybe a little bit late but I blogged about how you can solve this problem:

Hi,

thanks for your answer. The Jira Issue is exactly what I need
Your first post helped me, the second comes a litte late...

I solved this Problem by writing: class="required ${Dummy.constraints?.iAmRequired?.nullable}"
so I get class="required true" or class="required false"

Maybe not the best way but it works

There's the bean fields plugin Marc Palmer released earlier this month:

http://grails.org/plugin/bean-fields

Might help you out a bit

I suggest you all use Marc`s plugin, this is an awesome functionality that IMHO, should be added to grails core.
