User.find(1)
for no record with gives:
def test_error_message
begin
User.find(1)
rescue ActiveRecord::RecordNotFound => e
message = e.message
end
assert_equal message, "Couldn't find User with 'id'=1"
end
I expected same behavior wiht find_by! method but it doesn't give so
descriptive message.
For example expected behavior should be:
def test_error_message_for_find_by!
begin
User.find_by(first_name: 'foo', last_name: 'bar')
rescue ActiveRecord::RecordNotFound => e
message = e.message
end
assert_equal message, "Couldn't find User with 'first_name'='foo' and
'last_name'='bar'"
end
but it doesn't work like this instead e.message is just general "Couldn't
find User".
My use case is that I have API and on application_controller level I
defined rescue from:
ApplicationController < ActionController::Base
rescue_from ActiveRecord::RecordNotFound, with: :record_not_found
def record_not_found(exception)
render json: { errors: [exception.message] }, status: 404
end
end
But in first case clients of API could guess what's error. But on second
example couldn't .
If maintainers agree I can submit pull request to change behavior.
