I have an application on Heroku that uses the Paperclip gem that recently had some issues - and I'm not 100% sure on what it was that caused it. I have the application working locally (including the image upload) - but I get an 'Application Error' page on the heroku url, and when I try to access the heroku console with heroku run rails c it gets an error of:
/app/vendor/bundle/ruby/2.0.0/gems/activerecord-4.2.1/lib/active_record/dynamic_matchers.rb:26:in 'method_missing': undefined method '_image_post_process_callbacks' for #<Class:0x007f8aaf5d2fa0> (NoMethodError)
A little background on the issue - another developer was working on creating an image upload model - which was named 'Images' - which I think caused problems with Paperclip, and wouldn't allow me to run a Rails migration. When I tried it said there was an issue with the 'Images' table, so after finding a similar situation online, I commented out the body of the 'def change' within the create_images migration - which now looks like so:
class CreateImages < ActiveRecord::Migration
def change
# create_table :images do |t|
# t.attachment :file
# end
end
end
I then ran another migration - started my server locally and everything was working. I then pushed my changes to heroku, did a rake db:migrate for good luck - and the heroku url is still showing 'Application Error'
If anyone has any idea of possible causes of these issues, it would be greatly appreciated! Thanks for reading!
EDIT
After running heroku run rails c I get this output.

First off, if you need to undo a migration on Heroku, you will need to un-comment out the body of your migration, push to Heroku, then run heroku run rake db:rollback in order to undo it and get your application working again in the interim.
If you are still having trouble, post the errors and any relevant code in your post.

You're defining test_should_get_help somewhere again, when it's already been defined. Make sure it's only defined once - put the function in a private block at the end of the file like this:
[file end]
private
def test_should_get_help
[blah]
end
If you need it in multiple files, try adding it as a helper.

The error seems to come from Devise auto generated files but I cannot figure out why it happens only in prodcution mode.
I think you tried to override the devise default behaviour using rails generate devise:controllers and you may have changed them badly.
Please be sure that:
You need to override the default controllers, unless you can remove controllers/users folder (If the name of your model you applied Devise on is Users)
Check syntax in all the files in controller/users.
I've been tasked with adding seeds to an existing Rails project. I've been given a list of twelve survey names and I'm supposed to create them all, storing their id (position in the list of surveys) and name values, then loop over them and add a placeholder survey_question to each. I know how to do it if I were to create a new migration, redefining survey_question as an attribute of survey, but I'm supposed to work with the existing structure where survey and survey_question are distinct classes. And I've hit a wall.
My thinking was to put all the survey names in an array, thus ordering them automatically when the database is seeded:
surveys = [
"SurveyA",
"SurveyB",
"SurveyC",
"SurveyD",
"SurveyE",
"SurveyF",
"SurveyG",
"SurveyH",
"SurveyI",
"SurveyJ",
"SurveyK",
"SurveyL"
]
Then write an each loop that instantiates the Survey class and stores the given name as the name attribute of the database entry. Within that same loop I define survey_question as a placeholder question (which some of you may recognize), and attempt to append it to the Survey being created with the << operator. This is my first point of failure:
surveys.each do |survey|
survey_question = SurveyQuestion.create(body: "What is the average flight speed velocity of an unladen swallow?")
Survey.create(name: survey) << survey_question
end
Great, I've written a loop. I need to verify that it does what I want it to do. So I go to re-seed the database and run rake db:seed. When I do, however, I get a validation error from a line in the seeds.rb file that came with the project. See here:

Here is the offending line (25) from the seeds:
#create seed region
usa = Region.create!(name: "USA")
So I thought, maybe for some wierd reason this was written when the database was created and cannot be overwritten, so if I clear out the database and start anew, it will populate without complaining. I ran rake db:reset. Wrong. At this point I realized there was an error in the way I'd written my each loop above. The error message told me that << is an undefined method for the survey object it was attached to. Here's that messsage.

As a final point of data I checked out what was actually in the database, just to see what was there. This is the result of SELECT * FROM "regions";:
erp_development=# SELECT * FROM "regions"
erp_development-# ;

So now I'm good and stuck. I've been learning as much as I can but my understanding of Ruby and Ruby on Rails is entry-level at best. If anyone out there in Stack-land can help shed some light on this for me I will forever be in your debt.
Thanks,
Brian
<< is Ruby Array method. Survey.create(name: survey) won't return you array, so this is the reason why it fails.
According to the documentation .create method returns the resulting object instead! http://apidock.com/rails/ActiveRecord/Base/create/class
survey = Survey.create(name: survey)
survey.survey_questions << question
The code above should work!
The << method just modifies the returning value of survey.survey_questions, it does not modify the object itself. You should use modifying methods like = or +=. Anyway, I think this is a cleaner way to do the same:
surveys.map do |survey|
Survey.create! do |s|
s.name = survey
s.survey_questions.build(body: "What is the average flight speed velocity of an unladen swallow?")
end
end
I'm trying to use rubber to deploy to my AWS EC2 for the first time. For testing im just using a t1.micro right now.
I get a weird error with rubber after having edited rubber.yml after tcap rubber:create_staging

Any idea where to look for an error? It seems like a simple problem to me but I dont really have a clue where to look..
Best,
M
Just remove rubber_env.
staging_roles: "#{known_roles.reject {|r| r =~ /slave/ || r =~ /^db$/ }.join(',')}"
# instead of
staging_roles: "#{rubber_env.known_roles.reject {|r| r =~ /slave/ || r =~ /^db$/ }.join(',')}"
There is this simple fix https://github.com/rubber/rubber/pull/406/files.
I'm trying to get Facebook logins working on my app using Rails, Authlogic, and Omniauth. I'm following the first steps of http://railscasts.com/episodes/235-omniauth-part-1 as precisely as possible.
I have:
added the omniauth gem, run bundle install.
created a new Authentication nifty-scaffold with fields user_id, provider, and uid.
added the route: match '/auth/:provider/callback' => 'authentications#create'
added to config/initializers/omniauth.rb:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, '20...my_app_id', 'bc...my_app_secret'
end
The server then fails to restart:

I had to do 'require "omniauth"' or 'require "omniauth-facebook"' in my config/development.rb file.
The omniauth gem was just bumped to version 1.0 as of yesterday (http://intridea.com/2011/11/2/omniauth-1-0), and there are some changes to how the gem is used that are not covered in the railscast.
I found my solution on this page: https://github.com/intridea/omniauth/wiki/OmniAuth-1.0
The biggest different is that each strategy is now contained within its own gem, so for facebook, you would change the line in your gem file that currently reads "gem 'omniauth'" to "gem 'omniauth-facebook'".
I didn't have to change any other code, and you may have to run "bundle update" to get everything to click through.
I just ran into this problem and this is what was wrong with me:
You can't have your facebook oauth gem in the Development list in your gem file. Heroku only reads the Production ones, so move it up out of the Development list.
