Bardwin on #75 Complex Forms Part 3 2011-11-19 21:00:09

In case anyone gets stumped by task.save(false), as of rails 3 use task.save(validate: false).

See 3.0 release notes: save(false) is deprecated, in favor of save(:validate => false) and the API.

The related error you may see is

NoMethodError (undefined method `[]' for false:FalseClass)

Evgeniy Shurmin on #284 Active Admin 2011-11-19 13:45:01

Can I integrate ActiveAdmin in views/layout/application.html.erb

<html><head> <title> .... </title> </head><body> ... <div class="active_admin"> active_admin yield </div> ... </body> </html>

SergiuR on #88 Dynamic Select Menus 2011-11-19 11:28:11

nice piece of app. I finally get it right. Thanks, I've been looking for this for a month already.

cmassao on #102 Auto-Complete Association (revised) 2011-11-19 10:53:10

good job!

i have one question.. method 'data:', is only in rails 3.1 ?

guyisra on #2 Dynamic find_by Methods 2011-11-19 09:42:09

Is this railscast still relevant?

I read that I need to use find(:all) now for 3.1

Dom on #111 Advanced Search Form (revised) 2011-11-18 16:24:04

There's nothing wrong with that approach either. I think it depends on the specific use case.

I have both strategies in one of my apps. Visitor searches on the public site are not stored, but admin searches in the marketing module are because they provide the criteria for targeting a segment of a marketing list which is then used by a backend job to send emails. Since the list changes as subscribers come and go, having the list based on search criteria is essential.

So this type of advanced search definitely has it's use case. Thanks for the revision Ryan.

Robert Brewitz on #277 Mountable Engines 2011-11-18 15:15:03

Using it for my puppy project, flows smoothly now after some tinkering :-)

sagit80 on #213 Calendars 2011-11-18 14:40:02

I have a weird issue...
calendar is generating for all articles in my blog e.g. I have 5 articles so each article has own calendar on main page.

<%= calendar_for @articles do |calendar| %>
<%= calendar.head('Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday')%>
<% calendar.day(:day_method => :published_at) do |date, articles| %>
<%= date.day %>
<% end %>

<% end %>

I'm using rails 3.1

How to fix it?

Chris on #283 Authentication with Sorcery 2011-11-18 13:17:01

Hi, receiving the following error when clicking my "Log In" link:

Routing Error

undefined method `username_attribute_name=' for #Sorcery::Model::Config:0x41a2730

Jonas M on #111 Advanced Search Form (revised) 2011-11-18 12:40:12

What's wrong with not having a database backend at all, configuring the attribute accessors manually and have the create action of the controller show the search result (after possible validations)? I guess re-using the search has its niceities, but how often will it actually get used in an average app?

Robert Brewitz on #277 Mountable Engines 2011-11-18 12:03:12

I got testing with rspec working here, note that I am using mongo(oid) and not ActiveRecord (same principle though):

https://github.com/RobertBrewitz/EngineRspecMongoid

NOTE: I think I found some bug in the rails plugin new generator with camel casing. More here: https://github.com/rails/rails/issues/3684

Cristiano Betta on #111 Advanced Search Form (revised) 2011-11-18 10:00:10

Just a small comment on the pruning of old searches. I think it's generally bad behaviour to remove old searches. People might link to it, expect it to remain, and boom, suddenly it's gone.

It's probably better to check if a specific search already exists before creation and redirect to it if need be.

Markus Schwarz on #283 Authentication with Sorcery 2011-11-18 08:06:08

Hi Ryan,
you should use »rails generate sorcery:install« instead of »sorcery:bootstrap«.
Have fun!

Murat Ustuntas on #111 Advanced Search Form (revised) 2011-11-18 05:33:05

Thank you Daniel.
I will just look at ElasticSearch with Tire gem. I assume that i would integrate ElasticSearch in my project.

Murat Ustuntas on #111 Advanced Search Form (revised) 2011-11-18 05:31:05

farukca: I just try to develop a file flowing. We have some papers comming from other companies. These files includes some unordered information. So somebody make ocr or writedown this unordered fields. And searching on it.

Julio on #47 Two Many-to-Many 2011-11-18 05:17:05

Hey Ryan! Thanks a lot!
I have a little problem here.
Do i have to make any changes in my controller? The view is perfect, but when I click "send", nothing is updated. Thanks!

farukca on #111 Advanced Search Form (revised) 2011-11-18 04:26:04

I had used ElasticSearch with mebla gem, it was working so good and easy to configure on production. But I will try solr this time, because it's mongoid configuration is so simple.
Murat hocam, sen nerede kullanacaksın fulltext aramayı ?

Daniel Errante on #111 Advanced Search Form (revised) 2011-11-18 02:14:02

Murat: Sunspot is a ruby wrapper for Solr. Another search engine to check out is ElasticSearch (and the Tire gem for it). It has some nice features like distributed indices for high availability and it's a lot easier than to set up than solr.

Milovan Zogovic on #285 Spork 2011-11-18 01:33:01

What could also speed up your process is to tell your specs to halt after first failure:

RSpec.configure do |config|
  config.fail_fast = true
  ..
end

Murat Ustuntas on #111 Advanced Search Form (revised) 2011-11-17 23:33:11

Thank you Ryan for this advanced search screencast.

Is there any suggestion for us about fulltext search engines? In Ryan`s screencasts, before,
he show us Sphinx and Sunspot, what about Solr?

Regards.

John Manuel on #294 Playing with PJAX 2011-11-17 23:07:11

Thanks VonD,

I finally had a chance to get back to this and discovered that tonight. After getting it working I came back here to let David know how I solved it. You are correct, the timeout is very low and at least for me running nginx/passenger/rails in dev mode is just too slow to respond. I changed the JS/CoffeeScript to:

          ruby
        
jQuery ->
   $('a').pjax('[data-pjax-container]', {timeout: 2000})

Now it's working find :)

Kunal Chaudhari on #293 Nginx & Unicorn (pro) 2011-11-17 21:58:09

i am getting this error when try to run sudo service unicorn restart

/usr/bin/env ruby-local-exec no such file or direcotry

i am using rbenv and have done 'rbenv local 1.9.2-p290' in my project

what can be the issue?

Anatoly Mikhailov on #294 Playing with PJAX 2011-11-17 21:18:09

I'm trying to use rack-pjax on the top div container and I can see the performance difference even the pushState reload whole body (header still loaded)

bobplates on #298 Getting Started with Spree 2011-11-17 21:10:09

ryan,

thanks for the railcast! as a noob, this is just what i have been looking for.

question.... the basic spree store that i got up and running seems to be missing a number of elements like the links for the shopping cart, search bar, etc.. and when you click on a product it goes to a blank page. this is different than what you illustrate here. i read that the basic spree install is basic... it just seems that the one i have set up is much more basic than the one illustrated. i would appreciate any advice or direction as to what i might be missing. i am using, spree 0.70.1, ruby-1.9.2-p290 and rails 3.1.1.

thanks,

bob

Jakub Arnold on #293 Nginx & Unicorn (pro) 2011-11-17 14:30:02

I don't know what happened, but restarting nginx and unicorn multiple seems to have solved the problem and it hasn't reappeared yet. I still wonder what caused it though.

Serguei Cambour on #285 Spork 2011-11-17 13:52:01

I followed by letter the screencast tuto but got the below errors:

Phillip Miller on #299 Rails Initialization Walkthrough (pro) 2011-11-17 09:43:09

Has anyone else noticed that http://guides.rubyonrails.org/initialization.html isn't in the guides index? Would've been helpful to have that link a year ago!

Gordon DuQuqesnay on #258 Token Fields 2011-11-17 08:32:08

It works but somehow mine seems slower than Ryan's. Am I missing something or did he do some creative video editing? ;)

Todd Miller on #298 Getting Started with Spree 2011-11-17 07:55:07

Any ideas as to why I receive the following error message when I run rake db:bootstrap --trace per the instructions in the readme for this episode?

Brendan Grainger on #169 Dynamic Page Caching 2011-11-17 07:36:07

Forget my comment above. It's working. Not sure what i was doing wrong. I updated the project to use bundler and it works fine. Thanks.

Jakub Arnold on #293 Nginx & Unicorn (pro) 2011-11-17 04:26:04

Hey, I'm having trouble with redirecting. I have the same nginx.conf as in the tutorial, and when I do redirect_to posts_path in my controller, I get redirected to http://unicorn/posts, instead of http://example.com/posts. What could've I missed?

Even if I do just redirect_to '/', I get redirected to http://unicorn/.

meltzerj on #299 Rails Initialization Walkthrough (pro) 2011-11-16 19:19:07

Wow... eye opening... I, as well, would love another one of these.

Brendan Grainger on #169 Dynamic Page Caching 2011-11-16 17:57:05

Hi Ryan,

I'm trying to get your example to work, but having no luck with content_for. There is never any content added in the layout where you have

          ruby
        
<%= yield :head %>

I pulled the latest code off github and having the same issue.

Giedrius Rimkus on #298 Getting Started with Spree 2011-11-16 13:31:01

How about seeing to integrating into existing app. Thanks for screencast! Great job!

Ryan on #298 Getting Started with Spree 2011-11-16 10:28:10

I used this script to install Image Magick on previous applications, seemed to work good: https://github.com/maddox/magick-installer

Ok guys I figured out my above problem, had to enable IPN for my paypal account.

Thanks

Thank!

Thank you Ryan,

In fact, with Active Reload the server is really fast in production mode.

Thanks

Nicolai Seerup on #182 Cropping Images 2011-11-16 06:17:06

I haven´t got the cropper module to work with Ryans code, but this works for me

          ruby
        
module Paperclip
  class Cropper < Thumbnail
    def transformation_command
      if crop_command
        crop_command + super.join(' ').sub(/ -crop \S+/, '').split(' ') # super returns an array like this: ["-resize", "100x", "-crop", "100x100+0+0", "+repage"]
      else
        super
      end
    end

    def crop_command
      target = @attachment.instance
      if target.cropping?
        ["-crop", "#{target.crop_w}x#{target.crop_h}+#{target.crop_x}+#{target.crop_y}"]
      end
    end
  end
end

Joe Sak on #158 Factories not Fixtures (revised) 2011-11-16 05:23:05

What about doing stubs and mock objects for request specs? I know it's possible in FactoryGirl but I never quite got the hang of it

rohandey on #289 PayPal Recurring Billing (pro) 2011-11-16 02:13:02

Is IPN working for anyone? I am not receiving IPN on payment made or for the recurrence.

My sandbox application is available on externally accessible domain.

Any help on this?

Thanks
Rohan

Adam Zaninovich on #228 Sortable Table Columns 2011-11-15 23:55:11

Sorttable is ridiculously easy to use, unobtrusive, and doesn't require all those http requests.

Thanks for the suggestion!

worthrd on #197 Nested Model Form Part 2 2011-11-15 22:18:10

Hello Ryan,

First of all thanks for the great work about nested objects. When i tried your example in my application IE gave me an error that object does not support method for jQuery hide() method. I did everything to figured out problem but none of them worked.

-copied jquery files to /assets/javascripts did not work !
-copied content of jquery.js file to application.js did not work!
-changed application.html.erb file like this
<%= javascript_include_tag "jquery","application", :cache=>true %> did not work.

My rails version 3.1.0

thanks..

Gabriel on #288 Billing with Stripe 2011-11-15 14:35:02

Great episode Ryan!

It would be AWESOME if you could go into more depth in stripe, even if it is with the pro subscription. It would be very very useful.

Thanks!

Gabriel on #289 PayPal Recurring Billing (pro) 2011-11-15 14:33:02

1 for this episode, but a future episode going into more depth in stripe would be + 100 !

Trung Lê on #298 Getting Started with Spree 2011-11-15 12:36:12

@Ryan: yet again you've done a great tutorial job. Thanks for covering this episode with Spree. In version 0.80, we plan to have the namespace for the sake integration with other such as RefineryCMS. I hope you will create another tutorial on Spree integration.

Ty Barho on #296 Mercury Editor 2011-11-15 12:04:12

The best way i've found to do this is to just add a route in your routes file like:

          ruby
        
match '/editor(/*requested_uri)' => 'mercury_auth#edit', :as => :mercury_editor

Then create a new controller that inherits from MercuryController, like:

          ruby
        
class MercuryAuthController < MercuryController
  include SessionsHelper

  before_filter :authenticate_with_admin, :only => [:edit]
  def edit
    render :text => '', :layout => 'mercury'
  end
end

Then, you can get all the functionality of Mercury, but limit access on requests like that. That might be a bit closer to what you were looking for.

Oh, and be sure to add that route before the mercury routes in your routes.rb file

VonD on #294 Playing with PJAX 2011-11-15 11:32:11

Maybe the request is just meeting a timeout, in which case it falls back to a normal request. You can configure the timeout delay, which is by default 650ms.

twixt01 on #102 Auto-Complete Association (revised) 2011-11-15 11:20:11

Tried this with locations for a new event. It was working fine then I deleted a location and it keeps trying to download a json file instead of displaying the index. Any ideas?

In addition to being a great video overall, it also just introduced me to tap. Thanks Ryan :)
