FakeCursor
[source]¶ Bases:
object
The Python Database API Specification has a cursor() method, which NoSql drivers generally don’t support. If the exception in this function is taken then it likely means that some piece of functionality has not yet been implemented in the driver. And something is using the cursor.

SQLALL
(table)[source]¶ Bases:
object
Helper class providing a comma-separated string having all the field names (prefixed by table name and ‘.’)
normally only called from within gluon.dal
-
class

SQLCustomType
(type='string', native=None, encoder=None, decoder=None, validator=None, _class=None, widget=None, represent=None)[source]¶ Bases:
object
Allows defining of custom SQL types
Parameters: - type – the web2py type (default = ‘string’)
- native – the backend type
- encoder – how to encode the value to store it in the backend
- decoder – how to decode the value retrieved from the backend
- validator – what validators to use ( default = None, will use the default validator for type)
- Example::
Define as:
- decimal = SQLCustomType(
- type =’double’, native =’integer’, encoder =(lambda x: int(float(x) * 100)), decoder = (lambda x: Decimal(“0.00”) + Decimal(str(float(x)/100)) ) )
- db.define_table(
- ‘example’, Field(‘value’, type=decimal) )
