I have a Model A which has many objects of Model B using a :has_many association. When I create a new object of model A, set its attributes, build associated objects and inspect the non-persisted objects, it works fine. However, as soon as I try to persist the objects using save or save!, I am getting the following back-trace.
NoMethodError: undefined method `insert_record' for #<Array:0x000000052541f8>

I am using ruby 2.0.0p195 with rails 3.0.5.
This could be an compatibilityproblem. Update your Rails to a newer version v3.2 >=
Also if you don't want to upgrade your Rails 3.0.x project, make sure you run in on the ruby version where you developed it, e.g. 1.9.2 or 1.9.3.
With rvm or rbenv that should't be a problem.

Ever since we updated to Rails 3.2.13 we've been unable to start the heroku rails console. The server is working just fine, but when we try to run the console, it gives the following error:

What is going on? Thanks!
Just experienced this myself. As it turns out the rb-readline gem bumped a version that causes rails console, and other things to fail. Try locking it to '~> 0.4.2'.
gem 'rb-readline', '~> 0.4.2'

Any inputs, on how can I debug this would be really helpful.
Thank you.
The Problem is this section in v0.12.0 (the one you are using) https://github.com/drapergem/draper/blob/v0.12.0/lib/draper/railtie.rb#L5-L8
When I look at the master branch they changed to code to look like: https://github.com/drapergem/draper/blob/master/lib/draper/railtie.rb#L5-L10
You should upgrade your draper gem to the latest release and see if the error still occurs.

I'm using Rails 3.1.1 and Ruby 1.9.2p290 (2011-07-09 revision 32553) on Linux. And db is postgres.
Here is the line mentioned in the first line of the error log:
constant = constant.const_defined?(name, false) ? constant.const_get(name) : constant.const_missing(name)
Oh, and I tried other combinations of this command: rails generate devise:install, rails g devise_install and it gives me the same effect
You are using a very old version of Devise that is not even meant to be used in production (it is a release candidate!). Please update your Devise version.
solution: add to gemfile:
gem 'devise', :git => 'git://github.com/plataformatec/devise.git'
I want to run cucumber command in rails 3 controllers,but I add 'gem firewatir' to gemfile,
when I 'rails server', I got this error,and page shows "Internal Server Error".

If I don't add 'gem firewatir' to gemfile, rails server can run,but when run the cucumber command, I get this error:
no such file to load -- firewatir (LoadError)
Anyone ever met this issue,or who know how to fix it? Thanks
I think it is a known (and fixed) problem: Watir and Rails 3.0.X incompatible
I'm not sure that this is the same thing since the stacktrace doesn't include any lines from commonwatir/firewatir. It could be something different, but can't say for sure.
I want to use the new Rails3 feature that allows you to embed a Sinatra app inside rails.
In my routes file, I have:
# app names changed to protect the (not so) innocent
MyApp::Application.routes.draw do
match "/service", :to => MyService
...
end
And in /lib/my_service.rb I have
class MyService < Sinatra::Base
get "/" do
"Hello World"
end
end
When I try to start the Rails server I get Uninitialized constant MyService (NameError), which I suspect means my Sinatra file is in the wrong directory. Where am I supposed to put it?

I found a good answer for this question, thanks to this article.
I was missing the all important requires header at the top of my routes file:
require 'my_service.rb'
# app names changed to protect the (not so) innocent
MyApp::Application.routes.draw do
match "/service", :to => MyService
...
end
