I'm trying to find where you call this very view. I think you made a typo there; product instead of products (this is how it's called in your urls.py file).

So I think it's in one of your references to this view. Change this to products, and it should work.

You can create a dictionary and set key as a range, like if you want range 0-1 key of dict will be 1, range 4-5 key of dict will be 5 etc. So we can create a function that will group students with certain pace:

I think this is what you're looking for:

In case it helps someone:

CA = custom authorizer

• error code: AWS doesn't fully allow a CA implementation to dictate the error code sent back to caller.
  • If the CA returns an Auth Policy which does not have resource/method that was invoked in one of the statements with action Allow, then user gets a 403 with something like "Not authorized to access resource"
  • If the CA returns an Auth Policy which has statements with action Deny that contains resource/method that was invoked, then user gets a 403 with something like "access denied explicitly with a Deny"
  • If the Exception raised by CA has message "Unauthorized" then user gets 401 with message "Unauthorized".
  • If CA throws an exception with any other message then user gets HTTP-500 internal server error (Authorizer Configuration Error) and call is rejected/not-authorized.
• error message: Only static control is allowed via Body Mapping Template in Gateway Responses.
  • E.g. you can update the Body Mapping Template for "Unauthorized [401]" in "Gateway Responses" to say "My service doesn't like you for some unknown reason" and then whenever CA throws "Unauthorized" exception the end user gets HTTP 401 with "My service doesn't like you for some unknown reason".
  • Similarly you can also update "Access Denied [403]" or "Authorizer Configuration Error [500]". But the message is static and can not be controlled from CA implementation.
  • It is NOT possible to have different 401 messages like:
  • 401: Unauthorized due to expired token.
  • 401: Unauthorized due to missing scope.

Other unrelated thing: Because the CA throws an exception in certain conditions to convey auth failure, from a metric point of view this increments the Lambda ErrorCount metric. So that metric isn't reliable to identify "application errors".

Try this. This will work for you.

I basically want to 'get' all the different components of a query, like the list columns selected, where conditions, sub queries, table names, etc.

Your tree variable holds all that data: ParseTree tree = mySqlParser.dmlStatement();

line 1:11 no viable alternative at input '_'

If you look at the lexer rules:

You can use the || in the custom callback function. Something like this:

Your app crashes due to Syntax error exception. You have a mistake in word EXITS, change it to EXISTS
