I am working on an application using meteorjs. I am totally new to meteor. In my application I am using dataTables with meteor for shorting , pagination and searching.
This is my template code
<template name="questions">
<div class="col-md-3">
{{#constant}}
<table class="table table-striped table-bordered table-condensed table-hover listing"
id="content_listing-table">
<thead>
<tr>
<th>Questions</th>
</tr>
</thead>
<tbody>
{{#each questions}}
<tr>
<td>
<a href="#" data-id={{_id}} class="edit"> {{questionSubString question_text}}</a>
</td>
</tr>
{{/each}}
</tbody>
</table>
{{/constant}}
</div>
</template>
and my meteor code is
Template.questions.rendered = function () {
$("#content_listing-table").dataTable();
}
Template.questions.questions = function () {
return Meteor.questions.find({topic_id: Session.get("currentTopicId")})
}
my problem is when i add a question to the database it doesn't seem on template. and generate an exception. I know this is because of datatables . and datatable is not update when document updated. i tried many examples from stackoverflow but couldn't get rid of this problem .I tried by appending row dynamically but it always give me a warning . and it doen't seems to do a right way. can i remove the datatables from the element dynamically? help will be appreciated EDIT:
$('#content_listing-table').dataTable().fnClearTable();
$('#content_listing-table').dataTable().fnAddData(Meteor.questions.find().fetch());
I am trying to do this first empty the table and then again add the data to it. But here it is emptying the table for not adding the data again.
You are using a
{{constant}}
region. This disables reactivity for that part of the template.Try getting rid of your constant region and run meteor using
meteor --release template-engine-preview-5.5
. This will run meteor using the new, in progress template engine Meteor UI. There are noconstant
s orpreserve
s in Meteor UI - it's smart enough to make DOM changes at a fine-grained level, so it should work out of the box with things like jQuery plugins.
