Hello, I would like to use a web2py json service but I am not sure how to
create the database query to do what I want to output the correct json.
This is what I have atm:
@service.json
def places():
project_info = db(db.project_info.id >
0).select(orderby=~db.project_info.id)
project_updates = db(db.project_updates.project ==
db.project_info.id).select(db.project_updates.ALL,
orderby=~db.project_updates.id, limitby=(0, 3))
humans = db(db.human_resources.project_id ==
db.project_info.id).select(db.human_resources.ALL,
orderby=db.human_resources.full_name)
return project_info, project_updates, humans
I would like to have project_updates and humans as sub queries of
project_info so they can intertwine with the outputted json.
Here is the structure of those tables and how I am calling the data using
Javascript any advice is greatly appreciated:
*cheers
