How to send object from 1 $state into another $state with ui-router

https://plnkr.co/edit/nqyBTcBgBimjkrpf2oYo?p=preview

Expected

After Login Selecting a Ticker button should make the Tags module display the matching Tags for that Ticker.

Results

After Login Selecting a Ticker button will replace the entire app in the index's ui-view with the Tags $state object.

App's current state path: -> login > container > tags

The ticker button click in the Tickers component:

$scope.clickTicker = function(ticker) {
  console.log(' Ticker clicked!', ticker)
  $state.go('tags', { ticker: ticker });
}

app.container.html (We go here after login) container state

<div>
  <dashboard-module></dashboard-module>
  <feed-module></feed-module>
</div>

dashboard.html dashboard state

<div class="jumbotron text-center">
    <h1>The Dashboard</h1>
</div>

<div class="row">
  <tickers-module></tickers-module>
  <tags-module></tags-module>
  <view-module></view-module>
  <social-module></social-module>
</div>

There is the updated plunker

Namely we have to set a tags state as a child of container one

  const tags = {
    // here we use parent as a placeholder for our child state
    parent: 'container',
    name: 'tags',
    url: '/tags',

also, the container state now in template has a target

<div ui-view>
</div>

And finally - tags stat has as a part of its template the tags-module

template: '<p>Tags State</p><tags-module></tags-module>',

Check it here and also to get more understanding about nesting, maybe check this:

Nested states or views for layout with leftbar in ui-router?

You need to have all route configs in one module, else the different routes (states) won't know about eachother.

You should check out how to do nested views/states: https://github.com/angular-ui/ui-router/wiki/Nested-States-&-Nested-Views
