[sqlalchemy] Re: Multiple tables forming one class?
And btw, in case I didn't understand what you wanted and you really
wanted to map one class to several tables, you'll find information
about that there:

I'm fairly new to this, and trying to understand the ORM relationship
between a class and a table row. In most of the examples in the
documentation, there is a one-to-one relationship; a class instance
corresponds to a row of a table.
In my application, my data falls into a 3-tier structure, represented
by tables A, B and C. Each A has zero or more Bs, and each B and zero
or more Cs. So, A-B is one-to-many, and B-C is one-to-many.
From an application perspective, the only type of entity is a A, the
only reason I have Bs and Cs is that SQL tables cannot have repeating
columns (my previous database experience is with a non-SQL database
that allows repeating data items!). I think of the Bs and Cs as just
part of the particular A to which they belong.
*If* I understood your point correctly (sorry if it's not the case), I
think you are looking for one-to-many relationships to the object
itself. This can very well be done. Just remember a one-to-many
relationship from A to B is expressed in your table as a foreignkey
from B to A !
http://www.sqlalchemy.org/docs/datamapping.html#datamapping_relations_onetomany
Now, in Python I can represent all the data for a particular A (ie A+B
+C) together in one item, say a nested dictionary.
A nested dictionary will probably be quite hard to do with SQLAlchemy alone.
My question is, can the SQLAlchemy ORM do this for me - i.e. have a
single class A which maps to my 3 tables A,B,C and knows how they
are joined? If so, what should my class and table declarations look
like (and for bounus points, can I specify the declaration using
Elixir).
In elixir, what you asked above (again assuming I understood what you
wanted) would translate to:
class A(Entity):
has_field('name', String) # or whatever fields has the table
...
belongs_to('parent', of_kind='A')
has_many('children', of_kind='A')

[sqlalchemy] Determining class of ORM attribute at run-time
I'm creating a general routine that is intended to take an arbitrary dict of attribute / value pairs and an ORM object instance, and use the dict to update the properties of the ORM instance, without knowing a priori whether the attributes might be relations to other tables. The problem I ran in to is when a property that is a relation needs to be created anew, because then I don't know what class to create an instance of. From looking at the source, I found what I was looking for under the argument attribute of the PropertyLoader class, so I am currently doing along the lines of: attr_class = object_mapper(ormvar).properties[attr].argument new_instance = attr_class() setattr(ormvar, attr, new_instance) However, this feels like it might be a bit fragile, as the argument attribute isn't explicitly document that I could find. Is there an API / documented way of determining the class that represents a particular attribute, as determined by mapper() or relation()? Hope this makes sense.

The selectfirst:

Could the problem have something to do with the column being Numeric

column name on your table. if you want to send me the Table for
that i can try to create a test out of it.

The selectfirst:
request = session.query(StudyRequest).selectfirst(
and_(model_table.c.model_acronym == acronym,
study_request_table.c.model_request_counter == counter,
model_table.c.model_id == study_request_table.c.model_id))
Could the problem have something to do with the column being Numeric
instead of OracleNumeric? Seems to be that way because reflection was
overridden.

yeah also whats your mapper on that ? is there a string-based
order_by in there somewhere (or in the query.selectfirst() call) ? i
dont understand why that name wouldnt be truncated.
