I have this sample json of a list of "Fruit":
{
"apple":{
"color":red"
"taste":"sweet"
}
"pineapple":{
"color":yellow"
"taste":"sour"
}
}
I want to use a very object oriented approach to retrieve a property of my
entity using a string key.
The requirements:
1) NDB must not be able to store any "Fruit" without the "color" or "taste"
fields. (JsonProperty does not meet this requirement)
2) "apple" and "pineapple" are unique identifiers, used to retrieve it's
corresponding fruit data, NDB must not be able to store multiple fruit
objects containing the same unique identifier.
class Fruit(ndb.Model):
name = ndb.StringProperty(required=True)
color = ndb.StringProperty(required=True)
taste = ndb.StringProperty(required=True)
class Person(ndb.Model):
favoritefruits = ndb.StructuredProperty(required=True,repeated=true)
Then to find apple,
person = Person.get_by_id("Johnathan").favouritefruits
for fruit in person.favoritefruits:
if fruit.name == "apple"
# found apple!
The problem:
Multiple "Fruit" objects containing the same "name" property can exist in
the "favoritefruits" property.
What solutions are there that will fulfil both requirements 1) and 2)?
