Question

username =  self.request.get('username')
groupName =  db.GqlQuery("SELECT group FROM Person WHERE name = :1", username).get()

I’m getting error “Parse Error: Expected no additional symbols at symbol group”. What is wrong?

---

objPerson = Person.get_by_key_name(username) # load
self.response.out.write(str(objPerson))

It returns “None”

Answer 1

GQL != SQL
You can’t select a specific field in GQL (other than __key__)

person =  self.request.get('username') groupName = 
  db.GqlQuery("SELECT * FROM Person WHERE name = :1", username).get()
group_name = person.group

Also you might want to consider using the buitin key_name to store and retrieve Person entities instead of query for them.

Person(key_name = username) # store
Person.get_by_key_name(username) # load
