postgresql - Rails case sensitive applications with Postgres -

-

i'm running new rails app on postgresql , not understand why on earth made postgreql case sensitive , didn't make option turn off.

i mean, really, if registeres "sam" on site, won't able log in "sam", there can 2 different accounts "sam" , "sam". disaster, taking consideration fact all other major databases case insensitive.

now instead of looking user like

user.find_by_name(params[:name])

i'll have this

user.all(:conditions=>["name ilike ?", params[:name]]).first

i can't believe there's no way avoid in rails because destroys 1 of main principles of framework: database independence.

is there better way implement case insensitive username/e-mail schema?

i suppose have 2 db columns, if preserving case important you:

  • one login name, convert lower case when user signs up, , use login user, after converting name login form lower case
  • one display name, what's displayed username , user gave @ signup
