How can I avoid "Assertion Failed: `id` passed to `findRecord()` has to be non-empty string or number" when refreshing an ember page? - ember.js

Question

There's this really annoying feature about Ember that I'm not sure how to get around. I may have a url that looks like the following
http://{my-blog-name}/posts/view/{some-blogpost-ID}
The way I get to this page is by clicking on a link inside of my {my-blog-name}/posts page. This works and will display the page as expected. However, if I try to refresh the page, or if I just literally type my http://{my-blog-name}/posts/view/{some-blogpost-ID} into my url search box, I will get
Assertion Failed: `id` passed to `findRecord()` has to be non-empty string or number
Here is how I navigate to the posts/view/{some-blog-id} page.
post.js
import Ember from 'ember';
export default Ember.Route.extend({
model: function() {
return this.store.findAll('post');
}
});
posts.hbs
<li class="title-list-item">{{#link-to "posts.view" posts}}{{posts.title}}{{/link-to}}</li>
view.js
import Ember from 'ember';
var siteId;
export default Ember.Route.extend({
model(params) {
siteId = params.site_id;
return this.store.findRecord('post', params.site_id);
}
});
view.hbs
<div id="Links">
<h1 id="blog-header-title">My Blog</h1>
<!--<p>{{!#link-to 'welcome'}} See about me{{!/link-to}}</p>-->
{{outlet}}
</div>
{{outlet}}
router.js
import Ember from 'ember';
import config from './config/environment';
const Router = Ember.Router.extend({
location: config.locationType,
rootURL: config.rootURL
});
Router.map(function() {
this.route('index', { path: '/' }); // This is usually automatic if path undeclared, but declared here to support /index below
this.route('posts', function() {
this.route('view', {path: '/view/:post_id'});
});
this.route('welcome');
}
This is really frustrating because it means I can't make a blog post and share the link with a friend. Why does this happen and is there a good way to get around it?

Answer 1

posts.js route is returning all the posts available, that's the RecordArray.
<li class="title-list-item">{{#link-to "posts.view" posts}}{{posts.title}}{{/link-to}}</li>
so in the above posts - refers to single post model or RecordArray of post model ?. if the above is single model then you will receive params.post_id in model hook of view.js, currently you are taking params.site_id instead of params.post_id.
Reason for not executing the model hook.
https://guides.emberjs.com/v2.13.0/routing/specifying-a-routes-model/#toc_dynamic-models
Note: A route with a dynamic segment will always have its model hook
called when it is entered via the URL. If the route is entered through
a transition (e.g. when using the link-to Handlebars helper), and a
model context is provided (second argument to link-to), then the hook
is not executed. If an identifier (such as an id or slug) is provided
instead then the model hook will be executed.
