to create a document and insert it into a database:

Copy Code code as follows:

>>> doc = {' foo ': ' Bar '}
>>> Db.save (DOC)
(' E0658cab843b59e63c8779a9a5000b01 ', ' 1-4c6114c65e295552ab1019e2b046b10e ')
>>> doc
{' _rev ': ' 1-4c6114c65e295552ab1019e2b046b10e ', ' foo ': ' Bar ', ' _id ': ' E0658cab843b59e63c8779a9a5000b01 '}

The Save () method returns the ' _id ', ' _rev ' field
querying the database by ID

Copy Code code as follows:

>>> db[' E0658CAB843B59E63C8779A9A5000B01 ']
<document ' e0658cab843b59e63c8779a9a5000b01 ' @ ' 1-4c6114c65e295552ab1019e2b046b10e ' {' foo ': ' Bar '}>

>>> data = db["5FECC0D7FE5ACAC6B46359B5EEC4F3FF"]
>>> data[' billseconds ' = 191
>>> Db.save (data)
(U ' 5fecc0d7fe5acac6b46359b5eec4f3ff ', U ' 3-6b8a6bb9f2428c510dcacdd5c918d632 ')

>>> for ID in DB:
... print ID
...
' E0658cab843b59e63c8779a9a5000b01 '
