Python: How to store an array in Google App Engine datastore

Question

I am working on a project where I process a URL and get an array (containing columns and rows) using beautifulsoup. Now I need to store this data in the datastore. I cannot find any reference on storing an array in the datastore.

Answer 1

A multivalued property is represented in the datastore api as a python list. If you can organize the data in list, you can define a part of your data model as

class MyData(ndb.Model):
    array = ndb.StringProperty(repeated=True)

In the request handler, store the data like

data = MyData()
data.array = list_you_got_from_request
data.put()
