Thanks for your help, I got the GET and POST methods working.
PUT for updating and DELETE don't seem to work though.
I changed my API on your suggestion to wrap dict() around the DAL calls:
@request.restful()
def secapi():
response.view = 'generic.'+request.extension
print "args ",request.args
print "vars ",request.vars
#pprint.pprint(request, indent=4)
def GET(*args,**vars):
patterns = 'auto'
parser = db.parse_as_rest(patterns,args,vars)
if parser.status == 200:
return dict(content=parser.response)
else:
raise HTTP(parser.status,parser.error)
def POST(table_name,**vars):
return dict(db[table_name].validate_and_insert(**vars))
def PUT(table_name,record_id,**vars):
return dict(db(db[table_name]._id==record_id).update(**vars))
def DELETE(table_name,record_id):
return dict(db(db[table_name]._id==record_id).delete())
return dict(GET=GET, POST=POST, PUT=PUT, DELETE=DELETE)
But, I see this:
curl -X GET http://localhost:8007/apitest/default/secapi/secrets/id/21.json
{"content": [{"datavalue": "othertest", "id": 21}]}
Can do my get, then I try:
curl -X PUT -d "datavalue=updated" http:
//localhost:8007/apitest/default/secapi/secrets/id/21
invalid arguments
I see "invalid arguments" and the row is not updated:
curl -X GET http://localhost:8007/apitest/default/secapi/secrets/id/21.json
{"content": [{"datavalue": "othertest", "id": 21}]}
Is my use of curl incorrect, or is the api function for PUT coded
incorrectly?
Sorry if it's a simple thing
Thanks
