   HITTypeId, CreationTime

   expired

      Has this HIT expired yet?

class class boto.mturk.connection.HITTypeId(connection)

   Class to extract an HITTypeId structure from a response

class class boto.mturk.connection.MTurkConnection(aws_access_key_id=None, aws_secret_access_key=None, is_secure=True, port=None, proxy=None, proxy_port=None, proxy_user=None, proxy_pass=None, host=None, debug=0, https_connection_factory=None, security_token=None, profile_name=None)

   APIVersion = '2012-03-25'

   approve_assignment(assignment_id, feedback=None)

   approve_rejected_assignment(assignment_id, feedback=None)

   assign_qualification(qualification_type_id, worker_id, value=1, send_notification=True)

   block_worker(worker_id, reason)

      Block a worker from working on my tasks.

   change_hit_type_of_hit(hit_id, hit_type)

      Change the HIT type of an existing HIT. Note that the reward
      associated with the new HIT type must match the reward of the
      current HIT type in order for the operation to be valid.

   create_hit(hit_type=None, question=None, hit_layout=None, lifetime=datetime.timedelta(7), max_assignments=1, title=None, description=None, keywords=None, reward=None, duration=datetime.timedelta(7), approval_delay=None, annotation=None, questions=None, qualifications=None, layout_params=None, response_groups=None)

      Creates a new HIT. Returns a ResultSet See: http://docs.amazonw
      ebservices.com/AWSMechTurk/2012-03-25/AWSMturkAPI/ApiReference_
      CreateHITOperation.html

   create_qualification_type(name, description, status, keywords=None, retry_delay=None, test=None, answer_key=None, answer_key_xml=None, test_duration=None, auto_granted=False, auto_granted_value=1)

      Create a new Qualification Type.

      name: This will be visible to workers and must be unique for a
         given requester.

      description: description shown to workers.  Max 2000 characters.

      status: 'Active' or 'Inactive'

      keywords: list of keyword strings or comma separated string.
         Max length of 1000 characters when concatenated with commas.

      retry_delay: number of seconds after requesting a
         qualification the worker must wait before they can ask again.
         If not specified, workers can only request this qualification
         once.

      test: a QuestionForm

      answer_key: an XML string of your answer key, for automatically
         scored qualification tests. (Consider implementing an
         AnswerKey class for this to support.)

      test_duration: the number of seconds a worker has to complete
      the test.

      auto_granted: if True, requests for the Qualification are
      granted
         immediately.  Can't coexist with a test.

      auto_granted_value: auto_granted qualifications are given this
      value.

   disable_hit(hit_id, response_groups=None)

      Remove a HIT from the Mechanical Turk marketplace, approves all
      submitted assignments that have not already been approved or
      rejected, and disposes of the HIT and all assignment data.

      Assignments for the HIT that have already been submitted, but
      not yet approved or rejected, will be automatically approved.
      Assignments in progress at the time of the call to DisableHIT
      will be approved once the assignments are submitted. You will be
      charged for approval of these assignments.  DisableHIT
      completely disposes of the HIT and all submitted assignment
      data. Assignment results data cannot be retrieved for a HIT that
      has been disposed.

      It is not possible to re-enable a HIT once it has been disabled.
      To make the work from a disabled HIT available again, create a
      new HIT.

   dispose_hit(hit_id)

      Dispose of a HIT that is no longer needed.

      Only HITs in the "reviewable" state, with all submitted
      assignments approved or rejected, can be disposed. A Requester
      can call GetReviewableHITs to determine which HITs are
      reviewable, then call GetAssignmentsForHIT to retrieve the
      assignments.  Disposing of a HIT removes the HIT from the
      results of a call to GetReviewableHITs.

   dispose_qualification_type(qualification_type_id)

      TODO: Document.

   static duration_as_seconds(duration)

   expire_hit(hit_id)

      Expire a HIT that is no longer needed.

      The effect is identical to the HIT expiring on its own. The HIT
      no longer appears on the Mechanical Turk web site, and no new
      Workers are allowed to accept the HIT. Workers who have accepted
      the HIT prior to expiration are allowed to complete it or return
      it, or allow the assignment duration to elapse (abandon the
      HIT). Once all remaining assignments have been submitted, the
      expired HIT becomes"reviewable", and will be returned by a call
      to GetReviewableHITs.

   extend_hit(hit_id, assignments_increment=None, expiration_increment=None)

      Increase the maximum number of assignments, or extend the
      expiration date, of an existing HIT.

      NOTE: If a HIT has a status of Reviewable and the HIT is
      extended to make it Available, the HIT will not be returned by
      GetReviewableHITs, and its submitted assignments will not be
      returned by GetAssignmentsForHIT, until the HIT is Reviewable
      again.  Assignment auto-approval will still happen on its
      original schedule, even if the HIT has been extended. Be sure to
      retrieve and approve (or reject) submitted assignments before
      extending the HIT, if so desired.

   get_account_balance()

   get_all_hits()

      Return all of a Requester's HITs

      Despite what search_hits says, it does not return all hits, but
      instead returns a page of hits. This method will pull the hits
      from the server 100 at a time, but will yield the results
      iteratively, so subsequent requests are made on demand.

   get_all_qualifications_for_qual_type(qualification_type_id)

   get_assignment(assignment_id, response_groups=None)

      Retrieves an assignment using the assignment's ID. Requesters
      can only retrieve their own assignments, and only assignments
      whose related HIT has not been disposed.

      The returned ResultSet will have the following attributes:

      Request
         This element is present only if the Request ResponseGroup is
         specified.

      Assignment
         The assignment. The response includes one Assignment object.

      HIT
         The HIT associated with this assignment. The response
         includes one HIT object.

   get_assignments(hit_id, status=None, sort_by='SubmitTime', sort_direction='Ascending', page_size=10, page_number=1, response_groups=None)

      Retrieves completed assignments for a HIT. Use this operation to
      retrieve the results for a HIT.

      The returned ResultSet will have the following attributes:

      NumResults
         The number of assignments on the page in the filtered results
         list, equivalent to the number of assignments being returned
         by this call. A non-negative integer, as a string.

      PageNumber
         The number of the page in the filtered results list being
         returned. A positive integer, as a string.

      TotalNumResults
         The total number of HITs in the filtered results list based
         on this call. A non-negative integer, as a string.

      The ResultSet will contain zero or more Assignment objects

   get_help(about, help_type='Operation')

      Return information about the Mechanical Turk Service operations
      and response group NOTE - this is basically useless as it just
      returns the URL of the documentation

      help_type: either 'Operation' or 'ResponseGroup'

   get_hit(hit_id, response_groups=None)

   static get_keywords_as_string(keywords)

      Returns a comma+space-separated string of keywords from either a
      list or a string

   static get_price_as_price(reward)

      Returns a Price data structure from either a float or a Price

   get_qualification_requests(qualification_type_id, sort_by='Expiration', sort_direction='Ascending', page_size=10, page_number=1)

      TODO: Document.

   get_reviewable_hits(hit_type=None, status='Reviewable', sort_by='Expiration', sort_direction='Ascending', page_size=10, page_number=1)

      Retrieve the HITs that have a status of Reviewable, or HITs that
      have a status of Reviewing, and that belong to the Requester
      calling the operation.

   grant_bonus(worker_id, assignment_id, bonus_price, reason)

      Issues a payment of money from your account to a Worker.  To be
      eligible for a bonus, the Worker must have submitted results for
      one of your HITs, and have had those results approved or
      rejected. This payment happens separately from the reward you
      pay to the Worker when you approve the Worker's assignment.  The
      Bonus must be passed in as an instance of the Price object.

   grant_qualification(qualification_request_id, integer_value=1)

      TODO: Document.

   notify_workers(worker_ids, subject, message_text)

      Send a text message to workers.

      TODO: Document.

   search_hits(sort_by='CreationTime', sort_direction='Ascending', page_size=10, page_number=1, response_groups=None)

      Return a page of a Requester's HITs, on behalf of the Requester.
      The operation returns HITs of any status, except for HITs that
      have been disposed with the DisposeHIT operation. Note: The
      SearchHITs operation does not accept any search parameters that
      filter the results.

   search_qualification_types(query=None, sort_by='Name', sort_direction='Ascending', page_size=10, page_number=1, must_be_requestable=True, must_be_owned_by_caller=True)

      status of Reviewing.  Similarly, only Reviewing HITs can be
      reverted back to a status of Reviewable.

   set_sqs_notification(hit_type, queue_url, event_types=None)

      Performs a SetHITTypeNotification operation so set SQS
      notification for a specified HIT type. Queue URL is of form:
      https://queue.amazonaws.com/<CUSTOMER_ID>/<QUEUE_NAME> and can
      be found when looking at the details for a Queue in the AWS
      Console

   The top-most element of the QuestionForm data structure is a
   QuestionForm element. This element contains optional Overview
   elements and one or more Question elements. There can be any number
   of these two element types listed in any order. The following
   example structure has an Overview element and a Question element
   followed by a second Overview element and Question element--all
   within the same QuestionForm.

      <QuestionForm xmlns="[the QuestionForm schema URL]">
          <Overview>
              [...]
