A quick google for psycopg multiple statements doesn't turn up
anything useful, so I suspect you are going to be out of luck. And
unless there are more database drivers than sqlite that support an
executescript method, it doesn't seem likely that it'll get added to
SQLAlchemy either...
For batch
this is normal, loading for the base class only hits those columns which
are defined for that base class - it does not automatically fan out to all
columns mapped by all subclasses.
to do so, you can specify with_polymorphic:
Ahh, thank you very much Michael that does do exactly what I want.
Hi all,
I have a really short experience of python so it can be really stupid
question.
I tried to understanding about declarative_base().
Example below:
Base = declarative_base()
class Bus(Base):
__tablename__ = 'bus'
In my understanding, That python code look like function

How this function is return class, not instance? Is it kind of design
pattern?
I know It is not a big deal for just using SQLAlchemy, but
Oh, I see! It is return class literally. Thanks for your code.

declarative_base is just a function that returns a class. In python, a
class is a first class object just like any other. You can do things like
this:
class MyClass(object):
pass
def foo()
return MyClass
my_class_instance = foo()()
In normal use of SQLAlchemy you don't need to think too
I went though the exact same process of discovery that you did Jonathan :)
It does work perfectly but does not get rendered properly when printing out
the queries (possibly even when I set echo=True on the connection, if I
remember correctly)

Yes, obviously :) But I meant in general for any python type - native
postgresql type; I guess there are not that many really I could just handle
all the cases I want to use..

ironythe purpose of MetaData is to *avoid* global state. If any Table

yeah, the `echo` in my debug log is what showed me that postgres was

Sounds good. I will try concating strings for Postgres - see if that works.
Seems like it should maybe work from a few posts I read.
I tried out the insert on SQLite by zipping the dict keys to values - works
great!
I tried out the triple-quoting of the strings through SQLAlchemy but that
did

is a live database used by many applications), I'm trying to use a two-step

I'm attempting to do some universal filtering using a custom Query class.
In this case, I'm trying to filter out all items marked as archived in two
related classes. I'm having some trouble adding the required filters to
the query at all the right levels.
I'm using Flask 0.9, SQLAlchemy
