WIP notes...
Simple list and edit the title
Template (books.hbs):
<h1>Books</h1>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th class="vtop">Author</th>
<th>
Title
<br><small class="small not-bold">(Click on the title for editing)</small>
</th>
<th class="vtop">Release Year</th>
<th class="vtop">Library</th>
</tr>
</thead>
<tbody>
{{#each model as |book|}}
<tr>
<td>
{{book.author.name}}
</td>
<td>
{{#if book.isEditing}}
<form {{action 'saveBook' book on='submit'}} class="form-inline">
<div class="input-group">
{{input value=book.title class='form-control'}}
<div class="input-group-btn">
<button type="submit" class="btn btn-success" disabled={{book.isNotValid}}>Save</button>
<button class="btn btn-danger" {{action 'cancelBookEdit' book}}>Cancel</button>
</div>
</div>
</form>
{{else}}
<span {{action 'editBook' book}}>{{book.title}}</span>
{{/if}}
</td>
<td>{{book.releaseYear}}</td>
<td>{{book.library.name}}</td>
</tr>
{{/each}}
</tbody>
</table>
Route (books.js):
import Ember from 'ember';
export default Ember.Route.extend({
model() {
return this.store.findAll('book');
},
actions: {
editBook(book) {
book.set('isEditing', true);
},
cancelBookEdit(book) {
book.set('isEditing', false);
book.rollbackAttributes();
},
saveBook(book) {
if (book.get('isNotValid')) {
return;
}
book.set('isEditing', false);
book.save();
}
}
});
We need all Authors, download them in model hook with Ember.RSVP.hash.
In setup controller we separate these models.
model() {
return Ember.RSVP.hash({
books: this.store.findAll('book'),
authors: this.store.findAll('author')
});
},
setupController(controller, model) {
const books = model.books;
const authors = model.authors;
this._super(controller, books);
controller.set('authors', authors);
},
Create editAuthor and cancelAuthorEdit action:
editAuthor(book) {
book.set('isAuthorEditing', true);
},
cancelAuthorEdit(book) {
book.set('isAuthorEditing', false);
book.rollbackAttributes();
}
Template:
<td>
{{#if book.isAuthorEditing}}
Editing: {{book.author.name}}
<button class="btn btn-danger" {{action 'cancelAuthorEdit' book}}>Cancel</button>
{{else}}
<span {{action 'editAuthor' book}}>{{book.author.name}}</span>
{{/if}}

We cannot use a simple input box in this case. Need a select box.
For our select box, we need a helper.
$ ember g helper is-equal
- Implement selects
- Add actions for saving relations
- Firebase adapter buggy, we have to manually remove previous relations
