ruby - Rails exists? Case insensitive - 


model.exists?("lower(email) = ?", params[:email].downcase)

returns error: argumenterror (wrong number of arguments (2 0..1)):

is possible exists? case insensitive match?

all need this:

model.exists?(["lower(email) = ?", params[:email].downcase])

it's looking single argument you're providing two. using array form , find-style conditional should need.
