ruby on rails - Why is ActiveRecord/PostgreSQL not finding my data in the database? -


i'm sure simple i'm overlooking since i've been dealing strange issue few days i'm asking help.

here apps setup , issue:

a rails 3.2.13 app pg gem , following db scheme:

create_table "clients", :force => true |t|   t.string   "uuid"   t.string   "private_key"   t.datetime "created_at",  :null => false   t.datetime "updated_at",  :null => false end  add_index "clients", ["private_key"], :name => "index_clients_on_private_key" add_index "clients", ["uuid"], :name => "index_clients_on_uuid"

i have 2 rows in "clients" database. pictured below:

enter image description here

the issue

when perform simple "select * clients;" using rubymine database console rows pictured in screen shot above. when perform "select * clients id = 11;" row, there. however, issue when try perform "select * clients private_key = "mkrbnuzbqzutmzvdri00nzq3lthfnjetnji4otheruqzqkrf";" fails , shows following in console output...

sql> select * clients private_key = "mkrbnuzbqzutmzvdri00nzq3lthfnjetnji4otheruqzqkrf" [2013-04-17 20:09:51] [42703] error: column "mkrbnuzbqzutmzvdri00nzq3lthfnjetnji4otheruqzqkrf" not exist   position: 43

i've tried pulling row out of db utilizing active record helper methods...

client.exists?(:private_key => token) client.find_by_private_key(token)

however, nothing works, never finds record exist in db. have idea going on here? need able utilize active record helpers, "client.exists?(:private_key => token)" able check , see if supplied token exists in db.

thanks help!

i tried client.find(12) see if find record id, , works. doesn't me understand why still can't use client.exists?(:private_key => token) or client.find_by_private_key(token).

update 4/19/13 @ 9:15am

the answer problem code generating private_key value adding return/white space end of value. when trying query db row based on private_key failing find anything.

to fix problem added gsub end of code generates private_key, this...

private_key = securityhelper.encrypt_private_key(client_uuid).gsub(/\s+/, "")

this strips white space generated private key , solved problem.

have tried 

client.exists?(:private_key => "mkrbnuzbqzutmzvdri00nzq3lthfnjetnji4otheruqzqkrf")

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
