Hello,
I have a base class I tend to use that includes a Boolean is_deleted field
so that pretty much every object has that available.
Is there a good pattern for setting a filter on these objects that
automatically adds a WHERE is_deleted = 'false'?
Or does that just have to be added as a

Hi all, I'm struggling a bit with best practices for my ETL application.
Each part of the ETL app is completely separate from the others, but I have
a MixIn for some common functions that each of them need to do, like move

Hi everyone,
This might be a totally premature optimization, but I want to at least
start off in the right direction.

I will reproduce this when I get done with work this evening and give the

This is probably a weirdly specific question, but I have a workflow that
involves loading lots of CSVs into Postgres. Some of them are very large,
so I want to cut overhead and not use CSV Dictreader. Wanted to use named
tuples instead.
Here's a header and a line from a file:
Hi Mohan,
Could you give us some more information about the structure of your
Dataframe and how you are using SqlAlchemy?

That's very interesting, Jonathan. Could you show me a quick example of
that approach? I'm not sure I *need* to do that, but I think I would learn
about SQLAlchemy from such an example and trying to understand it.

Thank you, as always, for both the specific answer and the general advice.
Much appreciated!

I have a generic CRUDService for my web app. It's a pattern that was
loosely suggested to me by Mike a while back. I've probably not implemented
it the way he intended, but it works pretty well in a pretty small amount
of code.
The main work, however, that needs to be done is in the read_all
parent and you then

I just realized that almost everything about how I'm using mixins here is
pretty much wrong. This is probably a garbage question and can be deleted,
but I don't want to do it myself in case someone is writing a response to
tell me that.

I like to keep my models separate from actions on it, so I only use them
for defining tables, relationships, and indexes. To perform actions on a
model I use a service that inherits from the model and provides . . . well.

Hi All,
Trying something out here for an analytics app here, and I'm not sure any
of this is a good idea. I'm trying to create a data model that's flexible
enough to handle a lot of different types of analysis. From plain CSVs to
time series to survey questions with complex hierarchies. My
Also, do be clear, what I have works. I'm passing the request object to the
model and then creating the engine based on the request. It works, but I
have a nagging feeling that this is not good and definitely not best.

I have a question about using creating engines along with pretty much any
python web framework, but I'm specifically working with Pyramid. For
obvious reasons. :)
The sqlalchemy docs state this:
"The typical usage of create_engine()
This is an admittedly wonky situation. And I don't have much code to offer
because I think the problem is conceptual on my part, rather than
code-related.
We're basically using google spreadsheets as a quick and dirty interface
for certain types of data entry. I know how terrible this is.
