Do this in a single query filter(ids in ticket_ids, event_id=event_id, deleted_at=None)

These checks should be in calculate amount function itself

Newly created order should be returned

As asked previously, never use update branch feature unless just before merging. The triggers and CI is ran again without any change for no reason and maintainers get a notification thinking that something has changed

prateekj117 · 2019-12-04T20:56:40Z

@iamareebjamal Done. I am thinking to refactor the whole calculate-order function in another PR.

iamareebjamal · 2019-12-04T22:06:41Z

This will allow deleted tickets as well. And as previously instructed, event filtering should be done here itself

app/api/custom/orders.py

prateekj117 · 2019-12-09T07:55:01Z

As mentioned previously, this should not be done

@iamareebjamal #6635 (comment)

No benefit of merging an intermediate state PR

@iamareebjamal I will start working on that PR as soon as this gets merged. I wanted to keep them separate as this PR already contains a big change. And the second change is more of a refactor.

Yes, that's why it can be taken in this PR only. It's not a huge change compared to what has been done already. It makes no sense to break something first and then fix later in a separate PR

iamareebjamal · 2019-12-09T13:52:00Z

+                break


What is this doing?

You have unnecessariy made an O(n) function to ne O(n^2)

prateekj117 · 2019-12-10T16:18:16Z

ticket_ids_found = {ticket_information.id for ticket_information in ticket_info_list}

+        return jsonify(status='Order Unsuccessful', error='Ticket with id {} was not found.'.format(tickets_not_found))


There can be multiple tickets not found. Also, send event ID as well. Ticket 324 may exist but not under the event requested

@iamareebjamal I am sending the list of all the tickets not found. Regarding example of ticket 324, I am already passing event_id as well which fetching the tickets, so those tickets will also throw tickets not found.

It will throw: Ticket with ID 324, 325, 326 was not found

Everyone wants to see: Tickets with ID 324, 325, 326 were not found in Event 432

Hence, again #6635 (comment)

It will throw: Ticket with ID 324, 325, 326 was not found in Event 432

This should not return JSON response. This function should have no idea about request or response or anything. This function does not know that it is part of flask application. This should be a pure python function, otherwise what was the point of extracting it out?
