Paginate in GSP with an array List - grails

Question

How can I use the <g:paginate\> tag to paginate an array list in a table?
I have this in my controller
def selectevents(){
def events = DomainEvents.findAllByMonth('June')
[events:events, count:events.size()]
}
And I have this in My GSP:
<table id="results-table" class="table table-bordered table-striped" style="width:100%">
<thead>
<tr style="background: #d3d3d3;">
<th style="width: 3%;text-align: center;"></th>
<th style="width: 10%;text-align: center;">Name</th>
</tr>
</thead>
<g:each in="${events}" status="i" var="eventsInstance">
<tr class="${(i % 2) == 0 ? 'odd' : 'even'}">
<td>-</td>
<td>${eventsInstance?.Name}</td>
</tr>
</g:each>
and then this:
<g:paginate next="Forward" prev="Back" maxsteps="5" controller="Controller" action="selectevents" total="${count}" />
But the pagination tag doesn't appear. I want to make a pagination to get 5 rows per page, some one?

Answer 1

Your code is calling DomainEvents.findAllByMonth('June') which is returning all of the events for the month of June. You only want to retrieve a subset of 5 of them and then use pagination to navigate around those subsets.
You probably want something like this in your controller:
def showEvents() {
params.max = 5
def count = DomainEvents.countByMonth('June')
def events = DomainEvents.findAllByMonth('June', params)
[domainEventsInstanceCount: DomainEvents.count(), domainEventsInstanceList: events]
}
And then something like this in your GSP:
<div class="pagination">
<g:paginate total="${domainEventsInstanceCount ?: 0}" />
</div>
I hope that helps.
