On this note: I have this blog post let’s say (with mongodb connection):
db.define_table('blog',
Field('author', 'string', requires = IS_NOT_EMPTY()),
Field('date', 'datetime', default = request.now),
Field('text', 'text'))
I can do: print db().select(db.blog.author) -> This will give me all the
author in the post
I can also use mongodb api to interchangeably:
import pymongo
from pymongo import MongoClient
client = MongoClient()
client = MongoClient('localhost', 27017)
db1 = client.foo #lets say foo is my database name
db1.blog.find_one() #here blog is my collection and I want the first
document
Out[3]:
{u'_id': ObjectId('55498fe02514971894c70538'),
u'author': u'Ron',
u'date': datetime.datetime(2015, 5, 5, 23, 51, 48),
u'text': u'This is my question'}
Question: is there an equivalent
db().select(db.blog.author) in pymongo api? For example if I use the above
implementation in pymongo:
db1.blog.author (wouldn’t work). But I can get specific author
db1.blog.find({‘author’:’Ron’}) That is also equivalent to:
db(db.blog.author == ‘Ron’).select()
So, there is two way to go about it. I know some of pymongo syntax wouldn't
apply to DAL as there are no sql equivalent to it. How is it the other way
around?
