AngularJS Question

How to display data from another table nested ng-repeat in angular js

I can display the data from one table using ng-repeat tag. but the problem is when I am trying to display data from another table according to previous ng-repeat.

in detail I have 2 table one for sections

section_id section_name

1 php

2 java


another table is lecture

id section_id lecture_name
1 2 basics
2 1 loops


i could display sections using ng-repeat. but i cant display lecture below corresponding sections

<div class="course_curriculum " ng-repeat="section in sections">

<ul class="sections" >
<h4>Section {{$index+1}}: {{section.section_name}}</h4>
<!--<h4>Section 1: Introduction to Mobile Application Development</h4>-->
<li>
<div class="section-head" ng-click="view_lecture(section.id)" data-toggle="collapse" data-target="#section{{$index+1}}" >
<i class="fa fa-bars" aria-hidden="true"></i> Course Lectures
</div>

<ul id="section{{$index+1}}" class="collapse" >
<li>
<ul ng-repeat="lecture in lectures">
<li >
<div class="section-sub-head" data-toggle="collapse" data-target="#sub1">
<i class="fa fa-bars" aria-hidden="true"></i> {{lecture.lecture_name}}

Answer

A couple possible issues in the code provided:

  1. Your inner ng-repeat is on the wrong element. It should be on the <li> element right above it. When nesting lists in bootstrap, you never repeat <ul> without wrapping each in atleast an <li> (usually an <a> too, which holds the dropdown text).
  2. To achieve nested tables (a list of lectures within each section), you want the lectures variable to be on each section. This would make your inner ng-repeat something like ="lecture in section.lectures".

Here is a working JSBin where I made the changes I listed above. I also removed a lot of your code, because it was broken without the rest of your controller.
