Imho Angular and Ember are not in 'versus' position. They both have their use cases.

somehow it now works out of nowhere. i think restarting the server helps!

btw.. solved.

Seems to be working just fine for me.

You know this is awesome sauce.

The most valuable thing however was

product.attributes = row.to_hash.slice(*accessible_attributes)

The thought is simple, it's mass assignment basics but would have never thought of it when importing excel files!

Super.

Btw... I got stuck how to use https://github.com/mikepinde/angular-ui-rails
on my angularJS application. I want to handle keypress event with it, but after I follow the steps in some tutorial (blog), it seems not worked. anyone can give me some good tutorial for "how to use angular-ui-rails"?

Cheers

I just did this, pretty good. The promise of Ember, imho, is that everything runs on the client, and the server just becomes a database passing json back and forth for persistance... Ember-data still needs work from what I'm told.

that's the million dollar question... If you find a good example, let me know...

After trying to learn Ember for the past few weeks, starting with the peep code tutorial I can say I'm just starting to "get it." And like everyone on this post I've been reading a TON about ember vs angular. But I haven't actually tried angular. Angular is backed by google! While Ember is two guys in a room, and sure other contributors. But it's the old David and Goliath, and who doesn't want to route for the underdog?

I've also noticed the advanced js programmers tend to use Ember over angular (at least the ones I know), I can only think they have good reason. And from what I can gather it's that you can do more complex things with Ember, at greater speed, once past the learning curve.

With this example, if we select United States or United kingdom it won't work. reason while filter state it is not able filter the value which have space. kindly someone help to get the values

Is it possible to import past activities? My app already has a lot of data generated by the User. Curious if there is a migration or some sort of import that exists with this for implementing it into an already existing app with a lot of data.

I was having troubles with throwing errors with ascii cast example:

@CommentPoller ->
  poll: ->
    setTimeout @request, 5000

turns out that needs to be as in the shownotes:

@CommentPoller =
  poll: ->
    setTimeout @request, 5000

I get undefined errors with the '->'

Liked the Active::Record stuff on that blog so I've bookmarked this for later reading.

Thanks

Yeah - I'm experiencing this too. I tweaked the code but now it appears to finds all the orders that are both in that state currently, or have at some point been in that particular state, which isn't quite working either.

After adding a tenant_id and default_scope, where is the best place to add this to be used by Rspec tests (where all database queries are currently failing due to the tenant_id being null)? Can I put this in a single place to be applied this across multiple tests?

Thank you

A little OT, but here's a link to SO with a way to hack Struct into a Rails project. I've just spent the morning reading up on Struct, OpenStruct, etc. and am amazed with the possibilities!

Didn't really know how to approach using OpenStruct or Struct before this episode. Thanks, Ryan!

In your ASCIIcast path is "/config/carrierwave.rb", but definitely it should be "/config/initializers/carrierwave.rb"

Lots of comments and posts and sample apps.
Is there any sample app or post that implements user login/session?

Is anyone using Spine? Would love to hear some comparison between Spine and Angular.

This railscasts doesn't cover how to handle config.action_controller.asset_host which is used when emailing for instance.

You want the email to link to the asset in the correct subdomain.

The solution I'm thinking to use looks like this:

config.action_controller.asset_host = Proc.new { |source, request = nil, *_|
  top_level = request.subdomain.split('.')[-1]
  domain = CONFIG['domain']
  '#{top_level}.#{domain}'
}

Though I'm not quite sure how to write a test for this.

How does this look when you have fields in both objects? How do create from a single form? For example, I want to track two different expense types: reimbursements and donations.

Reimbursements have a description, donations have name, address, etc., but both have an amount, a receipt, a category, and belong to an account.

I'm trying the polymorphic association approach, but having trouble figuring out how to create a new reimbursement/entry with all the necessary data and associated objects.

Hi guys, I am very very new to ROR so I really appreciate any help.

When I place the

           has_reputation :votes, source: :user, aggregated_by: :sum

in my post model, my page shows up as

"undefined method `has_reputation' for #Class:0x007fe5708753e0"

and then reloading turns it into

"undefined method `key?' for nil:NilClass"

If I take away these codes in my post model, the page will show fine then I try to click on the "up" button, and this shows up

undefined method `add_evaluation' for #Post:0x007fe57100e2c8

anyone can help me out? thank you so much

this is my post_controller

def vote
value = params[:type] == "up" ? 1 : -1
@post = Post.find(params[:id])
@post.add_or_update_evaluation(:votes, value, current_user)
redirect_to :back, notice: "Thank you for voting"
end

FYI... Rails 4 deprecates match routes. As far as I can tell, replacing "match" with "get" in config/routes.rb makes this episode Rails 4 friendly. Maybe that is obvious, but I was surprised the 'auth/:provider/callback' route wasn't a POST.

get 'auth/:provider/callback', to: 'sessions#create'
get 'auth/failure', to: redirect('/')
get 'signout', to: 'sessions#destroy', as: 'signout'

No, not within a .slim template, but you wouldn't really want to do that anyway. Way better to have it in its own .emblem file so you can precompile it and not even have to include emblem.js as something your browser has to load

@Alex, thanks a million for putting this together. It makes it WAY easier to connect the dots between this and traditional JS.

Hey man, thank you, I had same problem.

FYI, to those that have :inheritance_column set to something other than :type on the class you are calling :reset_column_information, make sure you set it again after the :reset_column_information call or it will give you the "column 'type' is reserved" error when running the migration.

This is because the class :inheritance_column setting is effectively ignored after you call :reset_column_information after the class is loaded. So, in short, assuming the Project class had :inheritance_column set to something other than :type, your migration should be:

Project.reset_column_information
Project.inheritance_column = nil #or whatever you have it set to
  Project.find(:all).each do |p|
    Project.update_counters p.id, :tasks_count => p.tasks.length
  end

Took a while for me to realize what was going on, so hopefully this saves someone some time.

Meteor 15min, Angular 16min, backbone 32min and Ember 25min+. Meteor Wins!

I've seen recently a Gem for creating such method encapsulation like memoization. It's called MethodDecorators, inspired by actual decorators existing in Python, you can find it on Github.

It's very interesting because of its extensive usage of metaprogramming and the way author mimics features of another programming language.

same here..I've followed the steps to install vagrant with rails but when I try to connect with localhost:3000 on windows it takes 1-2minutes to load the page.

If I execute a curl command on the vbox though I get the page in no time.

$ sudo vim /etc/nginx/sites-enabled/default

On line 22 (I think) you will see a line that says listen [::]:80 default_server; - comment that one out. then :wq [enter] to save and close.

Then try again: sudo service nginx start. Or just don't worry about it, as the file will be deleted later in the tutorial.

Hi Jose,

I cannot precisely answer your question regarding Travis CI. However you can find an article which covers the setup of TeamCity CI for automated headless testing of Javascript code - both Jasmine and CasperJS - in detail here:

http://www.jrubyonrails.de/2013/03/continuous-integration-for-jasmine--and-casperjs-tests.html

It might be a good starting point.

Nice. A direct translation will be http://jsbin.com/ihuqoz/2/edit

It uses an EntriesController.

Very true and the frontpage says it all.

A framework for creating ambitious applications

This is true for all of them actually: Angular is build by guys with strong technical background and if one will to master it than he should understand wide variety of JS templates: factories, providers, injectors and much more.
Ember is evolving so fast that almost all documentation is out of date :)
Joosy is just one of a kind - but I think Rails world only wins from the diversity it brings into it. Again I haven't work with it because of there wasn't such a demand, but I strongly belives that it have it's layer - large scale rich applications.
If one day content generated by Joosy will be compilant with search engines it will really shine as first-class sitizen in a lots of porjects.

ok..i've fixed this issue.but progress bar doesn't seem to finish. so you've any solution.

Joosy seems does not as easy to use as declared.

Is it possible to use Emblemjs in Slim templates?

Okay, guys you want a Ember vs Angular opinion - here it is:
Angular is more general and 'address root problem that HTML was not designed for dynamic views' in a very sleek way. It's directives is awesome - if u try it once you just cant forget how beautiful they are!
But he is not ready for a big applications, imho. Just look at his nested routing solution - it doesn't have one! There is only 3rd party module in angular-ui https://github.com/angular-ui/ui-router. No surprise it's version is 0.0.1
Ember is rails-aware and and it's your friend in a middle-size applications.
My opinion that Angular is a competitor rather to Backbone than to Ember. I'll use Angular if to drop interactivity here and there and use Ember for a to have a real front-side application, but... here is the sweet part - Joosy(http://www.joosy.ws/)!
So we have solutions for small, midle, and large front-end applicatoins, isn't this wonderful? :)

Your opinion on this is correct, it's just not worth the effort because all of the restrictions on concurrent connections. After trying many possibilities (ActionController::Live, Socket.io, Faye,... ) we decided to outsource the real-time component entirely to pusher.com - highly recommended. It takes literally minutes to set up and you don't have to worry about updating, uptime, compatibilities, scaling...

Great series of casts Ryan! VERY helpful!

Thank you very much :)

i'm running same code on my machine but this application is not working (https://github.com/railscasts/381-jquery-file-upload/blob/master/gallery-after)

i'm following all step.but images is not uploading.So plz give me your code.which you've uploaded on heroku. or give me any hint.

Does it help SEO, in the sense that all the membership-only material is made available for search engines such as google etc to scan?

Could someone point me to a resource to learn how to set it up so that I can use facebook authentication for an app on heroku and localhost:300 at the same time?

You can try to implement Angular's "Hello world" in jQuery. That's where jQuery solution will be more complex, and that's why I like Angular.

I created a gist with another example: https://gist.github.com/denispeplin/5096725

This code I'm using for displaying RRD graphs of different types. I will be surprised if someone will implement same thing in jQuery with same or less amount of JavaScript code.

+1 - when you put it like that, makes it seem very simple...
