Question

I have a controller like this :

def mytask = {
        def user = User.findByLogin(params.id)
        def mywork = user.schedules.daySchedules
        [ mywork : mywork ]
    }

Where I’m trying to find all the tasks assigned to a particular user. I have a corresponding view file :

<g:each in="${mywork}" var="tasks">
                <div id = "todayswork">
                        ${tasks.task}               
                    </div>
                    <div id ="Dates">
                        ${tasks.startTime}-
                        ${tasks.endTime}
                    </div>
                    <hr/>
            </g:each>

Logic works fine, I’m getting the output as I wanted. For example, if I go to http://localhost:8080/scheduleTest/daySchedule/mytask/anto my browser showing all the task for the user anto. But there is a problem in rendering it.

I’m getting the output as :

But I need the output something like this one:

How change my view file to get the appropriate output.

Thanks in advance.

It’s hard to tell from your examples, but my guess is you need to be looping over the tasks item, which appears to be a List in a List.

This means change this:

<g:each in="${mywork}" var="tasks">

to this

<g:each in="${mywork[0]}" var="tasks">
// or
<g:each in="${mywork.tasks}" var="tasks">

Again, I’m not exactly sure where the problem is occurring, but one of those will fix it.

The reason you are getting the output is that Groovy will automatically perform a property expansion on a list if the property is not defined on that list. Example:

use(org.codehaus.groovy.runtime.TimeCategory) {
    def d1 = 5.minutes.ago
    def d2 = 1.week.from.now
    assert [d1, d2].time == [d1.time, d2.time]
}

It’s the same thing as writing list*.property, and returns a new list containing each property on the original items.
