How to make modals which have routes like Trello in Emberjs - ember.js

I want to know how we can make modals which have routes.
In Trello, whenever you click on a card, the route changes from abc.com/b/personal to abc.com/c/some-random-string and the card opens in a modal. Also, when you close the modal, you get redirected to the previous url (abc.com/b/personal).
I want to know how can we achieve this using Emberjs.
Example: https://trello.com/b/ezWgKsol/sales-enterprise-feature-requests-sample

Here is my modal (using foundation) where we delete a record:
<div class="reveal" id="deleteLocationModal" data-reveal>
<div class="row">
<div class="columns">
Are you sure you want to delete this location?
</div>
</div>
<div class="row">
</div>
<div class="row">
<div class="columns">
<button id="cancelButton" class="secondary button" data-close type="button">Cancel</button>
<button id="deleteButton" class="button" {{action "deleteLocation" model}} data-close type="button">Delete</button>
</div>
</div>
</div>
The router has the falling in the actions hash:
actions: {
deleteLocation(model) {
Ember.assert("Params must be provided", model);
model.save().then(( /* response */ ) => {
this.transitionTo('locations'); //locations is my index page.
//flash message to inform the user of success.
});
}, (error) => {
//handle error.
// display flash message
// rollback any dirty attributes
});
}
I hope this helps,

Delete a record in Ember data not working

I have a table (a component) and a delete button in each row. When the the delete button is clicked the specific row should be deleted.
Tried the following code:
MyComponent.js
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
deleteCartRecord(cartDetails){
debugger;
this.sendAction('deleteRecord',cartDetails);
}
}
});
In MyComponent.hbs
{{#each model.orderParts as |newCart|}}
<div class="card-wrapper col-lg-12 col-md-12">
<div class="col-lg-2 col-md-2">
<div class="order-id">{{newCart.partNumber}}</div>
{{#if (gte newCart.promiseQty newCart.quantity)}}
<div class="order-status delivered">{{env.APP.StockAvailable}}</div>
{{else}} {{#if (gt newCart.promiseQty '0'(and (lt newCart.promiseQty newCart.quantity)))}}
<div class="order-status intransit">{{env.APP.LowInStock}}</div>
{{else}} {{#if (eq newCart.promiseQty '0')}}
<div class="order-status outofstock">{{env.APP.OutofStock}}</div>
{{/if}} {{/if}} {{/if}}
</div>
<div class="col-lg-3 col-md-3">
<div class="item-header">Delivery Date</div>
<div class="item-data">{{newCart.deliveryDate}}</div>
</div>
<div class="col-lg-2 col-md-2">
<div class="item-header">Required Qty.</div>
<div class="item-data">
{{increse-required-quantity incresedQuantity=newCart.quantity}}
</div>
</div>
<div class="col-lg-2 col-md-2">
<div class="item-header">Unit Price</div>
<div class="item-data">{{newCart.unitPrice}}</div>
</div>
<div class="col-lg-2 col-md-2">
<div class="item-header">Total Price</div>
<div class="item-data">{{newCart.partTotalPrice}}</div>
</div>
<div class="col-lg-1 col-md-1 button-colum"><button type="button" class="btn btn-danger" {{action "deleteCartRecord" newCart}}>Delete</button> </div>
</div>
{{/each}}
My Controller
import Ember from 'ember';
export default Ember.Controller.extend({
actions:{
deleteRecord(data){
debugger;
let confirmation = confirm("are you sure to delete");
if(confirmation)
{
debugger;
data.deleteRecord();
data.save();
}
}
}
});
The template file in which component is called

MyRoute
import Ember from 'ember';
export default Ember.Route.extend({
model: function()
{
return this.get('store').queryRecord('cart',{userId:1})
}
});
My Serializer
import DS from 'ember-data';
export default DS.JSONSerializer.extend(DS.EmbeddedRecordsMixin, {
primaryKey: 'totalPrice',
attrs: {
orderParts:
{
serialize: 'records',
deserialize: 'records'
}
}
});
I have the following issues:
In MyComponent.hbs, will newCart being passed as a parameter delete all the records or the specific record I want deleted?
Any ideas on why MyController is not invoked from the component?
Is this the correct way of deleting a record in ember?
Thank you in advance.
In MyComponent.hbs newCart is passed as a parameter will this delete all the record or the specific record i want?
It will delete the particular record alone. if you want to delete all the record then you can try unloadAll('model-name')
MyController is not invoked from the component why is that?
You need to send action upcon calling component, {{my-component deleteRecord=(action 'deleteRecords') }} . Actually real problem is, you are calling deleteRecord but in controller you got deleteRecords.
Is this the correct way of deleting a record in ember?
If you want to delete right away then you can use destroyRecord this will delete and save record immediately
Well, your example is full of bugs...
In MyComponent.hbs, will newCart being passed as a parameter delete all the records or the specific record I want deleted?
Nope.
Firstly, you need to understand that the result of store.query in your route returns a DS.ManyArray(an Array like object, which is model in your example) contains group of DS.Model instances (which should be newCart in your example, but you must change to {{#each model as |newCart|}} first). And only this DS.Model has method .save() and .deleteRecord().
The action you set on the button is {{action "deleteCartRecord" newCart.partNumber}}, so you actually passing a property called partNumber to deleteRecord and running deleteRecord and save on this property. Unless this partNumber is a DS.belongsTo pointing to another DS.Model, or it cannot work at all.
But what you wanted is to delete newCart, right?
Any ideas on why MyController is not invoked from the component?
Your invoke is right. But since your component is full of bugs, it must be throwing exceptions somewhere else and the app cannot run already.
Is this the correct way of deleting a record in ember?
I think I answered enough in the first question.

Template for modal from remote page

I am implementing modals as an ember component and I was wondering if and how could this be accomplished: If the content of the modal is coming from a different page, how would it be rendered as a template:
Example:
http://jsfiddle.net/koala_dev/NUCgp/918/
The script above opens a modal with this content:
http://fiddle.jshell.net/bHmRB/51/show/
But what if I wanted some extra data that depends on specific users, coming from the routes model? How would I insert something like
{{#each link in links}}
{{#link-to 'link.url'}}{{link.title}}{{/link-to}}
{{/each}}
into the remote page, so it would be rendered as a template, and not regular text?
Here is a very quick and easy example just to give you a right direction. You can play with it and parse the html to extract content (which is not relevant to the question).
You can setup a component for modal element. I've setup a component property (attribute) contentURL where you can set the url of the content.
Component handlebars
Notice the {{content}} which we used later in the action to save the ajax result. Action showModal is added on the link to execute the ajax call.
<script type="text/x-handlebars" id="components/bootstrap-modal">
<a data-toggle="modal" data-target="#myModal" {{action "showModal"}}>Click me !</a>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">{{content}}</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
<!-- /.modal-content -->
</div>
<!-- /.modal-dialog -->
</div>
<!-- /.modal -->
</script>
Component JS
App.BootstrapModalComponent = Ember.Component.extend({
/*initModal: function(){
}.on('didInsertElement'),*/
contentURL: null,
content: 'Content is loading...',
actions: {
showModal: function(){
var self = this;
var contentURL = this.get('contentURL');
if(contentURL == null){
this.set('content', '<p>No content url is given</p>');
}
console.log('get content from url > ' + contentURL);
$.ajax({
url: contentURL,
dataType: "html",
beforeSend: function(){console.log('before send');},
error: function(xhr, status, message){
console.log(message);
},
success: function (content) {
// parse and get the right html for the content
self.set('content', content);
}
});
}
}
});
Now you can call the component bootstrap-modal on your template like {{bootstrap-modal}}
For example:
<script type="text/x-handlebars" id="index">
{{bootstrap-modal contentURL="http://fiddle.jshell.net/bHmRB/51/show/"}}
</script>

Ember template does not remove when transition to different route

I feel as if this is a very simple problem to fix I am just not aware of how to fix it. Currently I have an outlet that displays a template like this:
user.hbs:
<div id="user-profile">
<img {{bind-attr src="avatarURL"}} alt="User's Avatar" class="profilePic"/>
<h2>{{name}}</h2>
<span>{{email}}</span>
<p>{{bio}}</p>
<span>Created {{creationDate}}</span>
<button {{action "edit"}}>Edit</button>
{{outlet}}
</div>
The template to be rendered at the outlet is this:
user_edit.hbs:
<div id="user-edit">
<h3>Edit User</h3>
<div class="panel-body">
<div class="row">
<label class="edit-user-label">Choose user avatar</label>
{{input class="form-control" value=avatarUrl}}
</div>
<div class="row">
<label>User name</label>
{{input class="form-control" value=name}}
</div>
<div class="row">
<label class="edit-user-label">User email</label>
{{input class="form-control" value=email}}
</div>
<div class="row">
<label class="edit-user-label">User short bio</label>
{{textarea class="text-control" value=bio}}
<div>
<div class="row">
<button {{action "save"}}>SAVE</button>
<button {{action "cancel"}}>CANCEL</button>
</div>
</div>
</div>
When I first visit the user route, the outlet does not display because the button has not been clicked. The button is hooked to a controller which takes care of the action. The action just transitions to the route where the template is displayed at the outlet. It appears just as expected but when I click on a different user model, the outlet from the previous user is still there without everything in the <div class="panel-body"> </div>. So Ember hides the panel-body div on transition but not the user-edit div. If you need more information I will be happy to provide it.
Here are the controllers:
userController:
App.UserController = Ember.ObjectController.extend({
actions: {
edit: function() {
this.transitionToRoute('user.edit');
}
}
});
Here is the userEditController:
App.UserEditController = Ember.ObjectController.extend({
actions: {
save: function() {
var user = this.get('model');
user.save();
this.transitionToRoute('user', user);
},
cancel: function() {
var user = this.get('model');
this.transitionToRoute('user', user);
}
}
})
Hi why dont you use {{#link-to 'edit' model}} instead of action ???
you can pass model to link-to so you dont have to get model in controller and then transitionToRoute
Look at this

ember-data handle server error

I am using ember-data 0.13 with rails. I have a basicinfo controller to handle basicinfo model update. update action is:
update: ->
#content.save()
#content.on('becameInvalid', (response) ->
alert Em.inspect(response.errors)
)
basicinfo.hbs:
<aside class='basicinfo-aside'>
{{#if inEditModel}}
<div class='control-group'>
<label for='basicinfo_about_me'>{{t '.basicinfo.edit.about_me'}}</label>
<div class='controls'>
{{view Em.TextArea id='basicinfo_about_me'
class='basicinfo-about-me'
name='basicinfo[about_me]'
valueBinding='aboutMe'}}
</div>
</div>
<div class='action-group'>
<span {{bindAttr class=':about-me-length-remain
hasAboutMeLengthRemain:muted:text-error'}}>
{{aboutMeLengthRemain}}
</span>
<button class='btn-cancel btn' {{action cancel}}>
{{t '.basicinfo.edit.cancel'}}
</button>
<button class='btn-update btn btn-primary' {{action update}}>
{{t '.basicinfo.edit.update'}}
</button>
</div>
{{/if}}
</aside>
<div class='basicinfo-inner'>
{{#unless inEditModel}}
<h5>
{{t '.basicinfo.about_me'}}
{{#if canManage}}
<a class='lnk-edit' href='#' {{action edit}}>
<i class='icon-edit'></i>
</a>
{{/if}}
</h5>
<p class='about-me'>{{aboutMe}}</p>
{{/unless}}
</div>
when I click update button with invalid data first time the error shows properly, but if I dont fix error and press update button again Ember shows: "Uncaught Error: Attempted to handle event willCommit on while in state rootState.loaded.updated.invalid. Called with undefined " How to solve it Thanks!
Ember data seems to be a little buggy when handling errors.
I would suggest you'd the following:
update: ->
#content.rollback() if #content.get('isError')
#content.save().then ((success_responce)->
<handle success responce here>
), (failure)->
<handle failure here>
Still a better solution in my opinion would be to disable the update button , based on the record.isError flag.
Another thing to consider is what to do when the server returns errors and you want to transition to another route (like with a cancel button).
Ember data will forbid you to ,complaining the record has inFlightAtrributes.
In this case you can again call record.rollback() to return the flags to initial state and continue your transition.

Bootstrap accordion with ember

Hi there i have a small question that belonging to my small ember application.
JSFiddle upload is here. I used bootstrap accordion to visualize my tickets. When i click on the "click" it adds another accordion into my view. But sadly it cannot be opened or used. Every accordion i dynamically created cannot be opened or closed. There is no error or exception thrown and from my point of view everything should work fine. My click-function looks like this:
click: function() {
this.counter++,
name = this.name+this.counter.toString(),
tre = App.Ticket.create({
Text: "try",
id: name
});
this.pushObject(tre);
}});
The belonging html is here:
<div class="accordion-group">
{{#each content}}
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="#accordion2" {{bindAttr href="id"}}>
Ticket ID/Störfall
</a>
</div>
<div {{bindAttr id="id"}} class="accordion-body collapse in ">
<div class="accordion-inner">
{{Text}}
</div>
</div>
{{/each}}
</div>
I hope you can help me.
You can add an action helper to the accordion link title
<a class="accordion-toggle" data-toggle="collapse"
data-parent="#accordion2"
{{bindAttr href="item.id"}}
{{action "click" item target="view"}}>
Ticket ID/Störfall
</a>
Then implement a click handler event in your view
App.TicketView = Em.View.extend({
click:function(context) {
var el = this.$('a[href='+context.get('id')+']');
el.toggleClass('collapsed');
this.$('#'+el.attr('href')).toggleClass('in');
}
});
Here's a working fiddle
