#createHITs(hit_template, question_template, hit_data_set) ⇒ Object
Create a series of similar HITs, sharing common parameters. Utilizes HITType
-
hit_template is the array of parameters to pass to createHIT.
-
question_template will be passed as a template into ERB to generate the :Question parameter
-
the RequesterAnnotation parameter of hit_template will also be passed through ERB
-
hit_data_set should consist of an array of hashes defining unique instance variables utilized by question_template

#updateHIT(hit_id, hit_template) ⇒ Object
Update a HIT with new properties.
- hit_id
-
Id of the HIT to update
- hit_template
-
hash ( parameter => value ) of parameters to update
Acceptable attributes:
-
Title
-
Description
-
Keywords
-
Reward
-
QualificationRequirement
-
AutoApprovalDelayInSeconds
-
AssignmentDurationInSeconds
Behind the scenes, this function retrieves the HIT, merges the HITs current attributes with any you specify, and registers a new HIT Template. It then uses the new ChangeHITTypeOfHIT function to move your HIT to the newly-created HIT Template.
