[sqlalchemy] Backport for 0.4 on Python 2.4?
I have to use PGArray fields, but I think this is only available using SQlalchemy 0.4. Easy_install only installs 0.4 when it detects Python 2.5. Is there some sort of backport available?

download the 0.4 distro directly and use setup.py to install it. im not sure what easy_install issue youre having (i only run py 2.4 here).

[sqlalchemy] Re: Generate dynamic tables and classes from external definitions

Hi!
I have an XML file that provides the information needed for table
creation (column names, types, etc.). Is there any easy way in
SQLAlchemy to dynamically build Table objects from this information?
So if I get something like
[{'name': 'firstname', 'type': 'string', 'length': 40}, {'name':
'lastname', 'type': 'string', 'length': 40}]
from the XML file, I want something like
mytable = Table('mytable', metadata,
Column('firstname', types.String(40)),
Column('lastname', types.String(40))
)
to be generated.
(oversimplified, I omitted stuff like primary_key, etc.)
A simple way would be to generate a code string from the information
and execute it with exec, but I'd like to know if there's a better way
to do this in SQLAlchemy.
Table is a class constructor, the Column entries are *args sent to
the constructor. just create Column objects on the flyi.e.
types = {'string':String, 'int':Integer}
res = []
for rec in xmlrecords:
res.append(Column(rec['name'], types[rec['type']], ...))
t = Table(*res)
build on this as necessary to get the type arguments in, primary key
flags, etc.

Installing it manually worked. I dont think its an Easy_install issue, it stated something about dependencies and 0.3.10 being the right version for Python 2.4 On Sep 23, 11:06 pm, Michael Bayer [EMAIL PROTECTED] wrote: download the 0.4 distro directly and use setup.py to install it. im not sure what easy_install issue youre having (i only run py 2.4 here).

[sqlalchemy] Re: Backport for 0.4 on Python 2.4?
yes thats because 0.3.10 is the current release version. 0.4 is hidden on the public cheeseshop listing so that people dont install a beta version as a production install.
