ng-repeat array of objects inside array of objects

Question

I am having trouble with ng-repeat for repeating properties of an object when it is inside an array and that array is inside an object which is inside another array of objects like this:

$scope.myJson = [{'id':1,'date':2,'nikola':[{'title':'a', 'name':'b'},{'title':'v', 'name':'b'},{'title':'d', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'}]},   
{'id':1,'date':2,'nikola':[{'title':'r', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'}]},  
{'id':1,'date':2,'nikola':[{'title':'z', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'},{'title':'a', 'name':'b'}]}];


<div ng-repeat='json in myJson'>
  <p>{{json.id}}</p>
  <p>{{json.date}}</p>
  <p>{{json.nikola.title}}</p>
</div>

json.nikola.title is not displaying every title in every nikola array. Thanks for the help.

What have you tried? You have to show what you expect of the result. What should the HTML render to? — Bjørn Sørensen

I actually did but obviously i didn't post the code the right way. The point is that i have that json and i need to ng-repeat properties inside 'nikola', what i do with the result is not important. — Uros

You should accept the answer of @BjørnSørensen below, it's correct with explanations. — Suicideboy

The reason you don't get an output is that you try to output an array as a single value. If you want each value in the array, you use ng-repeat on it as well.

When using ng-repeat you iterate over an array. As your first goal is to iterate over the main array with IDs this is done with

<div ng-repeat="item in myJson"></div>

You got this down. Further more you want to iterate over an array on each item. Same as before:

<div ng-repeat="subitem in item.nikola"></div>

There you have it.

<div ng-repeat="item in myJson">
    <div ng-repeat="subitem in item.nikola">
    </div>
</div>

You can then access the properties as you like on each repeater.

See this plunker for a running example on your data.

Add another ng-repeat to iterate the nikola object

<div ng-repeat='json in myJson'>
   <p>{{json.id}}</p>
   <p>{{json.date}}</p>
   <div ng-repeat='item in json.nikola'>
      <p>{{item.title}}</p>
   </div>
</div>`

Have you even tried before writing that ? You have to access id and date properties of json and property title of item to make it work.
