undefined method 'change' for :Fixnum when updating Timestamp value - ruby-on-rails

I'm using Google's OAuth2 API in a project, using Omniauth to enable creating the initial accounts with little effort, but in order to use the APIs I need to refresh the access_token since they're only valid for an hour, but I'm having an issue updating the expires_at value when I refresh the token.
Here's the code I'm using for requesting the token refresh:
require 'oauth2'
class Identity < ActiveRecord::Base
belongs_to :user
def refresh_access_token
case self.provider
when "google"
client = OAuth2::Client.new OAUTH_KEYS_CONFIG['google']['client_id'],
OAUTH_KEYS_CONFIG['google']['client_secret'],
{
:site => 'https://accounts.google.com',
:authorize_url => "/o/oauth2/auth",
:token_url => "/o/oauth2/token"
}
response = OAuth2::AccessToken.from_hash(client, :refresh_token => self.refresh_token).refresh!
self.update_attribute(:access_token, response.token)
self.update_attribute(:expires_at, Time.at(response.expires_at))
end
end
end
I get an undefined method 'change' for 1359936923:Fixnum error on the final update_attribute line for :expires_at (I split it from the line above to try and figure out the issue).
I've tried both the above update_attribute call, and also a simple self.expires_at = response.expires_at, with and without Time.at casting but all combinations result in the same error.
The :expires_at attribute is a Timestamp datatype. I've checked the response variable, it contains the timestamp correctly as far as I can tell:
--- !ruby/object:OAuth2::AccessToken
...
expires_in: 3600
expires_at: 1360019618
options:
:mode: :header
:header_format: Bearer %s
:param_name: bearer_token
...

If you can get away with it, you can turn off time zone awareness for your attribute, expires_at.
class Identity < ActiveRecord::Base
self.skip_time_zone_conversion_for_attributes = [:expires_at]
end
We are seeing the same issue because we have a Android app sending an Epoch time back to our website. Turning off time zone conversion for that attribute got rid of the error and so far seems to have no ill effects on the data. Of course, we're storing everything in UTC and so far this seems to be the only work around.

undefined method `each' for "":String with update_attributes

So I have an app that pre-register the users. Future user can claim their profile but the admin have to review it manually.
So, I have a table users and user_revision. If the claim is rejected by the admin I need to revert the change made.
Here is how I do it:
Followup.find(params[:followup]).user.update_attributes(UserRevision.find(followup.i_nid).attributes)
But for some reasons suddenly I have the following error, and I have no idea how to fix it:
NoMethodError (undefined method `each' for "":String):

I helped bl0b with this on the #rubyonrails IRC channel. Turns out that this line from the stacktrace:
activerecord (3.2.13) lib/active_record/associations/collection_association.rb:310:in `replace'
Indicates that AR is attempting to assign to a collection association. I asked OP to go through and attempt to assign each attribute one at a time in the update_attributes call. It turns out it was the services attribute which caused this, because there was also an association called "services" on the record.
Removing the services attribute from the list of attributes to be updated solves this problem.

cas_devise single sign out doesn't work

Building a CAS client in rails 3.2, I use the gem devise with the extension devise_cas.
Everything works fine login/logout.
BUT When I try to logout directly on the cas server, using the single_sign_out system everything breaks and I have no idea how to solve my problem since it seems to me that it come from the gem I use...
Here is what I get in my logs when the cas server try to inform me about the sign out:

EDIT
So I understand the problem come from this file at line 50.
I believe none of the session managers are recognized.
I have indeed removed ActiveRecord since i'm using mongoid, as mentioned in the installation doc. So should I install another session manager or something?
Devise can still its work without it (until the single-sign-out), so I believe it shouldn't be an issue?
Ok So the solution is the following:
As I can understand from this answer on gitHub, I am using the coockieStore to store my session, which is not supported by single sign-out.
So I would need to
use the ActiveRecord session store or some other database-persistent session store
I will update my answer when I will have find out what to do from here.
EDIT
So the solution was to use redis as session store. see redis-store and redis-rails gems.

New to ruby, can someone help me decipher this error from console?

I'm really just not sure what it means or what I'm supposed to do in order to get the webpage working on my localhost. Right now it is just showing an error that reads "We're sorry, but something went wrong." when I run rails server and open up localhost:3000 in chrome.
Here is the console output:

The other answers are correct in general. This exception in particular is caused by an incompatibility between older versions of the newrelic_rpm gem and Ruby 2.0. See rails #8885.
Update the newrelic_rpm gem and it should go away.
It is a null reference exception in your method detail_args_for (well technically a Nil reference exception). You are trying to call the method empty? on a variable that has a Nil value, which causes a problem because that isn't defined in nil
You're calling .empty? on a variable that hasn't been initialized somewhere in your detail_args_for method. It's probably to add an additional call to .nil? before checking .empty? if you want to allow Nil values:
if(!someVar.nil? && someVar.empty?)

Ruby on Rails Tutorial: 7.1.3 Could not find table 'users' using mysql

This question relates to switching from sqlite to mysql in rails prior to doing any database operations, while following the Ruby on Rails Tutorial (2nd ed.).
Before I did any database operations with the Ruby on Rails Tutorial (2nd ed.), I switched the database parameters in the config/database.yml to use mysql. Everything has been working up to section 7.1.3. So far the users table was created and a sample user was added to the table successfully. However, when I go to test the show users page at users/1 I receive the error message below. Is there something else that needs to be done when using a mysql database instead of sqlite? Thank you in advance for any support!

From the stacktrace you provided, it looks like your app is not pointing at your mysql database.
activerecord (3.2.11) lib/active_record/connection_adapters/sqlite_adapter.rb:472:intable_structure'` <-- points at the sqlite_adapter rather than a mysql adapter
Make sure you use the mysql2 gem and don't forget to run bundle install after modifying your gemfile. Also be sure to restart your server after modifying your database.yml file.

If you've installed refinery in an existing rails app with your own devise model, then you'll need to modify the refinerycms-blog gem to reference your devise model.
You'll want to look at line #14 in refinerycms-blog / app / models / refinery / blog / post.rb
rake refinery:override model=refinery/blog/post
and line #105 of refinerycms-blog / app / views / refinery / blog / admin / posts / _form.html.erb
rake refinery:override view=refinery/blog/admin/posts/_form
and for future reference here is a list of refinery objects that you can override
https://gist.github.com/2502881
I'm using version 2.1.0 and the above solution put me on the right track, but I had to tweak it it get it to work. I saw that the model and the view referenced by #kirley both refer to
Refinery::Blog.user_class
However, that user_class is set to the default Refinery::Blog::Post::Refinery::User class.
So I just dropped this in an initializer
Refinery::Blog.user_class = "User"
This allowed
rails generate refinery:blog
to succeed. Once that finished, I deleted my initializer and then uncommented the same line in the default refinery initializer to point to my Devise user model.
Refinery::Blog.user_class = "User"
