Don't override to_json like this

I don't know why our project override this method
class String
def to_json
"'#{self}'"
end
end

Because of this , The RJS totally don't work
and You get "unterminated string literal" because of not escaped javascript.

Possibility with scoped_proxy

class User < ActiveRecord::Base
scoped_proxy :admins, :find => { :conditions => ['role = ?', 'super_user'] }
scoped_proxy :has_login do |login|
{ :find => { :conditions => ['login = ?', login] } }
end
scoped_proxy :no_op do
nil
end
end

# This gives you the first administrator of the system
User.admins.find(:first)
# This counts the administrators
User.admins.count

# All users with a given login
User.has_login('foo').count
User.has_login('foo').find(:all, :order => 'created_at desc')

# And finally, I give you the no op
User.no_op.find(:all) # => User.find(:all)

psql: FATAL: IDENT authentication failed for user

Everytime I log in using normal user, I got this message:

$ psql -U gateadmin template1
psql: FATAL: IDENT authentication failed for user "gateadmin"

Why?

It looks like you would rather use password authentication than the
default IDENT-based auth (it's default in Debian distro of postgres
anyway). IDENT will only let you in when you do *not* use -U, ie,
your postgres user name is the same as your Unix user name. Change
this in pg_hba.conf, and don't forget to SIGHUP or restart the
postmaster afterwards.

Solution:

Just modify pg_hba.conf like this (change to trust)

local all trust
host all 127.0.0.1 255.255.255.255 trust
