Basically I have the following controller method:
def create
begin
@check_in = create_check_in()
rescue => exception
render json: { message: exception }, status: 500
end
end
and the following json.rabl file:
object @check_in => :event_check_in
attributes :id
What I try to achieve is to set manually the HTTP status code of the response. It currently responds with 200, and I need it to be 201 instead.
I saw very few similar question and the answer was generally to render / respond_with from the controller action, so I tried something like this:
def create
begin
@check_in = create_check_in()
render @check_in, status: 201
rescue => exception
render json: { message: exception }, status: 500
end
end
but all my attempts failed, throwing various errors.
Is there a way I could set the status code?
The issue is you're passing in @check_in as the first argument of the render method when it expects the first argument to be a hash of options, including the status option.
Your status: 201 option is being passed in as a hash to the methods second argument and being ignored.
Typicallya render call will look something like:
render json: @check_in.as_json, status: 201
# or more commonly something like
render action: :create, status: 201 # the @check_in variable is already accessible to the view and doesn't need to be passed in
# or just
render status: 201
# since by default it will render the view with the same name as the action - which is `create`.
There are lots of ways to call render, see the docs for more.
-- EDIT -- Max has a great comment - I'd strongly advise against rescuing from all exceptions and also against doing it in a specific controller action. In addition to his suggestion, Rails 5+ supports :api formatting for exceptions out of the box or, if you need more, I'd look at a guide like this one.
