Is rubygems installed?  At the command line, type:

If nothing listed, type "gem install rubygems", preferably as root.

Newbie question - how to resolve 'wrong status line' error

iDev — 2012-05-24T10:13:42

Hi everyone

I'm learning Ruby on Rails and wanted to perform oAuth as follows for
a third party API. But I get an error as follows:

wrong status line: "<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN
\">"


//Code snippet
require 'net/https'
require 'uri'

class UsersController < ApplicationController

       < at >auth_url = "https://url/oauth/authorize?
client_id=#{< at >client_id}"
       url = URI.parse(< at >auth_url )
       req = Net::HTTP::Post.new(url.path)
       res = Net::HTTP.start(url.host, url.port) {|http|
http.request(req)}

< at >output = res.body
render :text => < at >output.inspect

   end

end


Any help to proceed is much appreciated.

Help with inserting multiple records via console

captain awesome — 2012-05-24T00:54:31

I'm fairly new to Rails and was wondering would it be possible to insert 
multiple records via the console?

I tried variations along the lines of this but all failed.
Article.create {:title => "Test title 1", :body => "Test body text 1, ..", 
:published_at => Date.today} {:title => "Test title 2", :body => "Test body

If this is possible, please help.

Thank you

Re: Heroku App Sending Blank Emails with Sendgrid

Swift — 2012-05-23T17:24:08

Hey,

I'm Swift, one of the developer evangelists over at SendGrid.  Sorry
that we didn't get back to you on our support channel - we get a high
volume of requests and sometimes things slip through the cracks.

Your problem is that you're using a deprecated syntax for composing
the email.  The preferred method is to use the mail function:

    def
registration_confirmation(user)·
      mail(:from    => 'Foo
<info-+LBmYUDmh58< at >public.gmane.org>',
           :subject => "Welcome to Foo,
#{user.first_name}!",
           :to      => "#{user.first_name} <#{user.email}
    end

You can find the docs for ActionMailer here:
http://guides.rubyonrails.org/action_mailer_basics.html

They're pretty extensive and definitely worth the read.

Let me know if you have any more issues!

Declaring list of string constnats for app

Michael Baldock — 2012-05-24T15:05:20

Hi All,

I'm building an app that compares statistics from sports games. Each
statistic has an "action" that defines what happened at that point in
time, for example "player has possession" is one such action string.

I use these strings to pull out / sort the statistics into meaningful
information, so these strings are used throughout the app.

I want to know a good place to have a list of global variables like
this. I have tried :

creating file called action_string_constants.rb in /lib.
In this file I declare a module :
module  ActionStringConstants

  MB_ACTION_STRING_PLAYER_HAS_POSSESSION = "player has posession"

end

I then try and use this in another class such as Player (model) with

include ActionStringConstants

However this returns a NameError (uninitialized constant
Player::ActionStringConstants):


I then thought of including this in application.rb, as I want to use
these constants in many files, but this returns a similar error when
trying to launch the app.

Where can I declare a string constant??!

This really should be simple!

Re: Errors and flash[:error]

Miguel A. — 2012-05-24T14:18:20

Not sure if I understand your issue, but I believe you are looking at 
nested resources and nested forms.

Rails can do this automatically for you if you generate a scaffolding.
But if you are looking for going through the created hash for the 
message, take a look at: 
http://railscasts.com/episodes/18-looping-through-flash


You must to the attribute verification in its own model, rails will take 
care of the rest, the flash error message will display the validations 
for both models.

Heroku Deploy - assets issue_paperclip

Miguel A. — 2012-05-24T14:10:47

Hi all, I'm deploying my app on heroku for tests and have noticed
something odd.

I'm rails 3.2.3 and paperclip do handle the displaying/uploading images
process.
Everything runs smooth on my localhost but on Heroku, if I upload a
picture and the App isn't "accessed" for like during the night, in the
morning the image is not there and the 'broken image icon' takes its
place.

If I re-add the image and keep accessing the website for like, every
hour, everything is fine and all the images are there.

It's worth mentioning that I'm saving my images in paperclip's default
path, in the public->assets folder. And for testing, I wanted to keep it
that way.

Will this issue go away if I set the path to my app->assets folder?

Or does this have anything to do with the inner workings of Heroku,
assigning one dyno and then idling after some time with no hits, and
when the application "wakes up again" another dyno is assigned and the
app loses its uploaded images?

Is storing in Amazon S3 the only way of solving this or does altering
the path of paperclip to the App folder solves the problem?
If so, will it be a reliable option for a production stage?

Thank in advance for enlightening a RoR beginner,

Regards

Errors and flash[:error]

Brian — 2012-05-24T13:35:16

What is the relationship, if any, between the errors array for one of
my models and flash[:error]? Are validation errors automatically added
to the flash? Is there a helper I can use in my view to merge the
results?

Situation:

I provide a form, of sorts, for creating HABTM relationships between
two other models. The HABTM model does a bunch of validation to make
sure it won't save an invalid record. Additionally, each of the models
being associated has an "owner" and I need to verify in my controller
that the owner matches my session data to prevent somebody from
creating associations on someone else's behalf.

I'd like to provide a bullet list of the combined results of
validation errors and session matching errors.

The UI on my form should prevent both types of errors. So from the end
user's perspective there is no meaningful difference.
