Exactly what I was looking for. Sure hope you come back to do more RailsCasts soon Ryan!

Great resolution! Thanks a lot!

wow thanks... crazy how things change. Just getting into this now and there's NOO way I would have figured that out

I have this issue as well and it's the only thing keeping me from deploying my app right now. I can do a skip_around_filter and the homepage (static pages) will work and so will the subdomain but this is not a good solution on controllers that have actions that either need to be scoped or unscoped. For example, the registrations controller needs to have the new/create actions unscoped so people can register for a new account and then have the edit/update action scoped so only the right user can update their account.

It seems like this railscast should have covered routing. I followed his railscast for subdomains but for some reason, doing a match doesn't do anything in rails 4.2. I think it's still supposed to be working but it has no affect on anything if I use constraints as I've found in the rails casts and on stackoverflow.

I guess I can do the skip filter now and try to be more specific in the registration controller.

This was yet another awesome tutorial. I have chosen to go with your custom locking mechanism in my current project. Although I had to figure out my way through using an added time based field in the database as you mentioned at the end of the video, I did make one change to your handle_conflict method, changing the line that reads:

errors.add name, "was #{values.first}"

to:

errors.add attribute, "was " + (values.first.blank? ? "blank" : values.first.to_s)

To handle cases where something was added to a blank field during edit.

I can't quite wrap my head around this, but while following this tutorial line-by-line, my Backbone app refuses to render the view template. Please point me in the right direction, as this is my first experience with Backbone, and I've been circling around this problem for the past two days.

This is my /entries.js file:

```javascript
class Raffler.Routers.Entries extends Backbone.Router
routes:
'': 'index'
'entries/:id': 'show'

    index: ->
            view = new Raffler.Views.EntriesIndex()
            $('#container').html(view.render().el)


    show: (id) ->
            alert "entry #{id}"```

If I were to replace $('#container').html(view.render().el) with $('#container').html('Raffler') , it would produce the desired outcome. I don't think the el attribute has a value.

My /index.jst.coffee file:

```javascript
class Raffler.Views.EntriesIndex extends Backbone.View

template: JST['entries/index']

render: ->
$(@el).html(@template())
this```

I got error saying that Uncaught TypeError: this.template is not a function

Any help is appreciated!!

Excellent screencast, Ryan Bates! I built it in Rails 4 and updated two lines to work with Savon 2. Thanks!

Came here with a similar intent to Kraig.

Does anyone know of any updated places to learn about Feedjira? I am running into errors, but can't find a resource to learn about how to set it up correctly in 2015.

This doesn't work anymore in Rails 4.2. Instead, use rescue_from.

Example:

class ApplicationController < ActionController::Base
  rescue_from User::NotAuthorized, with: :deny_access # self defined exception
  rescue_from ActiveRecord::RecordInvalid, with: :show_errors

  rescue_from 'MyAppError::Base' do |exception|
    render xml: exception, status: 500
  end

  protected
    def deny_access
      ...
    end

    def show_errors(exception)
      exception.record.new_record? ? ...
    end
end

Hey guys.

DEPRECATION WARNING: link_to_function is deprecated and will be removed from Rails 4.1.

Hope the following codes could help anyone. ;)

First. Pass args by data-["someAttributes] in a link

- link_to_function(name, "add_fields(this, \"#{association}\", \"#{escape_javascript(fields)}\")")
+ link_to(name, "#", "data-association" => "#{association}" , "data-content" => "#{fields}", :class => "link_to_add_fields" )

Then. Add an eventListener to the above link rather than to use link_to_function

+$(document).on("click", "a.link_to_add_fields", function(e){
+        e.preventDefault();
+        var link = $(this);
+        var association = $(this).data("association");
+        var content = $(this).data("content");
+        add_fields(link, association, content);
+});

Thanks a lot. You saved my life! :)

Hello. Ho could we set nested params inside controller method, if we have many nested params, so that we should iterate over them an set their values to something. I have asked about that here:
http://stackoverflow.com/questions/29901150/how-to-set-values-of-nested-parameters-in-rails-4-from-controller-method

when I go to http://production.foo.com/ I get "Apache2 Ubuntu Default Page" does anyone know what happened?

If anyone runs into a runtime error when trying to display the omniauth in yaml using this code RuntimeError raise request.env["omniauth.auth"].to_yaml

Try this instead render :text => "<pre>" + env["omniauth.auth"].to_yaml

Hi, how to hide terms that are not present currently in index(deleted from models)?

So, this may not be the issue, and I'm too late to help either of you, but in case someone else is looking for this: In Rails 4, you need to use <%= f.fields_for..., not
<% f.fields_for... Note the = after <%.

Generally, your Rails application is probably not the best place to consume RSS feeds. Most of it needs to happen asynchronously to prevent your app from becoming slow. It's also a mess to deal with multiple formats and breaking feeds.

For this reason, APIs like Superfeedr exist and we recently introduced a Rails Engine which makes all this very simple and elegant.

Ajax search is not working though simple search works fine. I am not getting any error as well in my log file. Following is my code:

show_workers.haml
= form_tag show_workers_agencies_path, :method => 'get' do
= hidden_field_tag :direction, params[:direction]
= hidden_field_tag :sort, params[:sort]
%p
= text_field_tag :search , params[:search]
= submit_tag "Search", :name => nil

workers= render 'workers'

_workers.haml
%table.pretty
%thead
%tr
%th= sortable "name"
%th Phone number
%th City
%th{:colspan => "3"}
%tbody
- @workers_list.each do |worker|
%tr
%td= worker.name
%td= worker.phone_number
%td= worker.city
%br
= paginate @workers_list

show_workers.js.haml
$("#workers").html("#{escape_javascript(render("workers"))}");

agencies_controller.rb
def show_workers
@workers_list = Worker.where(agency_id: current_user.agency.id).order(sort_column + " " + sort_direction).search(params[:search]).page(params[:page]).per(5)
respond_to do |format|
format.html
format.js
end
end

application.js
$(function() {
$("#workers th a").on("click", function() {
$.getScript(this.href);
return false;
});
});

Please tell if I am missing anything.

For those who have need PDFtoXLS...

Just found a solution.

I need to do this

def authorize
    if current_permission.allow?(params[:controller], params[:action], current_resource)
      current_permission.permit_params! params
    else
            if current_user.nil?
                    redirect_to new_user_session_path
            else
                        redirect_to root_url, alert: "Not authorized."
            end
    end
  end

Hi,

Not work for me with rails 4 got a redirect loop :(

Any idea ?

If you're looking for a non-blocking, real time Rails solution, check out Entangled: https://github.com/dchacke/entangled

check out here, the geocode actually suggests a way to test it. it's probably something new in their documentation

https://github.com/alexreisner/geocoder#user-content-testing-apps-that-use-geocoder

Here is a reddit post that really helped me get this working:

http://www.reddit.com/r/rails/comments/2chtgw/tagging_in_rails_4/

Any best practices about how to test Fragment Caching?

What happens if I use method: :get in link_to? Does that make any effect on loading of the page?

Do mercury.js have to be in assets/javascripts?
remove //= require_tree . in application.js is the only way to prevent load it on all pages?

I know that this is a old post and no one has posted here in 9 month but I having problem with searching numbers any one has a example. thanks

I know there is an alternative way like private pub, which is d'Anthes, and it don't have those errors, but it still won't work

So, anyone help me to make one?

Can some one help me use private pub to make messaging project?
I follow the tutorial here, but I don't know why it won't work,
is private pub outdated already?

and added a new product from curl?

The Tire gem has been retired in favor of the official elasticsearch-rails gem. Is there any chance we can get an updated cast with that? The new gem has decent documentation, but very few examples of real-world usage.

so why on earth Ryan did all that work? seriously...

Thanks for pointing this out! It saved me a bunch of time!

I don't know if someone have encountered this problem so I'm going to ask here. I have implemented this already and it's working but their is a little problem. On the first page all of the javascript are working for example lightbox(html5lightbox), but for the remaining pages that is generated the javascript isn't working.

I'm using it in rails 4 ruby 2.2 and isn't working anything I should know?, thks
