Status 405 from the task queue

Question

I want to resolve a status 405 that I get from the task queue when trying to generate a report:

2012-02-16 03:56:53.012 /report/ 405 3ms 0kb AppEngine-Google; (+http://code.google.com/appengine)

2012-02-16 03:56:53.007 /createreport/ 302 20ms 0kb Mozilla/5.0 (X11; Linux x86_64; rv:2.0) Gecko/20100101 Firefox/4.0
I 2012-02-16 03:56:52.990 creating report task

The code that creates the task is 

class CreateReportHandler(webapp2.RequestHandler):

    def get(self):
        logging.info('creating report task')
        taskqueue.add(url=r'/report/')
        self.redirect('/')

and I have it routed with webapp2:

Route(r'/createreport/', handler=CreateReportHandler, name='createreport'),

then I should be able to make it a cron job but when I test it I get a 405 from the access of this code which times out if I try to run it directly:

class Report(webapp2.RequestHandler):

    def get(self):
        # Create a conversion request from HTML to PDF.
        users = User.query()
        today = date.today()
        startdate = date(today.year, today.month, 1) # first day of month   
        html = None     
        for user in users: 
            if user.activity() > 0:
                logging.info('found active user %s %s' % (user.firstname, user.lastname))

                    downline = User.query(User.sponsor == distributor.key).order(User.lastname).fetch()
                    for person in downline:  # to this for whole downline

                                silver = silver + amount*purchase.silver/1000.000 
                            if len(name) > 13:

                            if level == 4 and dist_level == 3:

                            if level == 4 and dist_level == 2:

                            if level == 4 and dist_level == 1:
                                bonus = 0.3

                            if level == 3 and dist_level == 2:                          
                                bonus = 0.03
                            if level == 3 and dist_level == 1:

                            html = html + '</td><td>' + str(bonus) + '</td><td>' + str(order.total)
                            bonusmoney = bonus * float(order.total)

                                    subject='Report %s %s' % (user.firstname, user.lastname))
                    message.body = 'Here is the monthly report'
                    message.to = 'niklasro@gmail.com'
                    message.bcc = 'fridge@koolbusiness.com'
                    message.attachments = ['report.pdf', asset.data]
                    message.send()
                    logging.info('message sent')

How can I resolve the status 405 and get through the execution?

Thank you

Solution

I came from GAE/J-land, so I am not familiar with Python, but I had encountered 405 response from my taskqueue worker before. In my case, it is caused due to setting the TaskOption method to POST while building the Task, while my handler only serves GET requests.

EDIT: After checking the TaskQueue.add() docs, it appears that the default method used if the method is not specified (as in your code example) is POST, while your handler appear to only able to serve GET requests.

My suggestion would be explicitly specify that your task uses GET method instead of POST, or change the handled method of your handler into POST instead of GET.

OTHER TIPS

Just want to add one possible scenario since a quick search of "taskqueue 405" all ends up in this page:

I got 405 errors because didn't specify a "target" parameter. taskqueue.add() ends up adding task to the default target, where my handlers are on a separate backend module.

If target is unspecified, then tasks are invoked on the same version of the application where they were enqueued. So, if you enqueued a task from the default application version without specifying a target on the queue, the task is invoked in the default application version.
