reactjs - React with Rails 5.1 Calling Database Objects into React Components -


how call rails 5.1 database object react component?

for example, in standard rails view, can call object using @object assuming have access configured in controller.

with rails 5.1, using webpacker enabled react functionality, how call rails database object react component?

i want map through @objects in database in react component.

with react-rails gem, can use access objects in jsx file:

 <%= react_component('component', props: @objects) %>

how do similar without using gem , using base rails 5.1/webpacker react setup?

my understanding uses ruby tag this:

<%= javascript_pack_tag "component" %>

in view template want render react component:

<%= javascript_pack_tag 'component' %>  <%= content_tag :div,   id: 'objects_data',   data: @objects.to_json %> <% end %>

this renders html tag

<div id="objects_data" data="[{"id": 1, "created_at": .....}]"></div>

then in js file

document.addeventlistener('domcontentloaded', () => {   var objectsdatatag = document.getelementbyid('objects_data')   const objectsdata = json.parse(objectsdatatag.getattribute('data')) })

now have json data stored in objectsdata constant.

my understanding how <%= react_component('component', props: @objects) %> works well.

this covered in bit more detail in webpacker docs , in this blog post

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
