Instance Method Details

#find_with_login(login) ⇒ Object

This method allows you to find a record with the given login. If you notice, with ActiveRecord you have the validates_uniqueness_of validation function. They give you a :case_sensitive option. I handle this in the same manner that they handle that. If you set false for the :case_sensitive option in validates_uniqueness_of_login_field_options this method will modify the query to look something like:

first(:conditions => ["LOWER(#{quoted_table_name}.#{login_field}) = ?", login.downcase])

If you don’t specify this it calls the good old find_by_* method:

find_by_login(login)

The only reason I need to do the above is for Postgres and SQLite since they perform case sensitive searches with the find_by_* methods.

# File 'lib/authlogic/acts_as_authentic/login.rb', line 95

def find_with_login(login)
  if validates_uniqueness_of_login_field_options[:case_sensitive] == false
    first(:conditions => ["LOWER(#{quoted_table_name}.#{login_field}) = ?", login.downcase])
  else
    send("find_by_#{login_field}", login)
  end
end
