And the relevant method from ActiveRecord::Base (line 1023 is the
options.update line):
{noformat}
def find_one(id, options)
conditions = " AND (#{sanitize_sql(options[:conditions])})" if
options[:conditions]
options.update :conditions =>
"#{table_name}.#{connection.quote_column_name(primary_key)} =
#{quote_value(id,columns_hash[primary_key])}#{conditions}"
# Use find_every(options).first since the primary key condition
# already ensures we have a single record. Using find_initial adds
# a superfluous :limit => 1.
if result = find_every(options).first
result
else
raise RecordNotFound, "Couldn't find #{name} with
ID=#{id}#{conditions}"
end
end
{noformat}
