Re: [sqlalchemy] Convert Declarative definitions to Table definitions
I use ENUM types for postgres. Reflection does not preserve the ENUM name within its sequence. Name is required on postgres. I don't want to edit my 50+ tables and add names to them just for a migration, this is why reflection does not work in my case. -- Thadeus On Mon, Dec 6, 2010 at 4:29 PM, Chris Withers ch...@simplistix.co.ukwrote: rate, you're better off reflecting the tables to be migrated rather than using any script to try and turn declarative models into table definitio -- You received this message because you are subscribed to the Google Groups sqlalchemy group.

Re: [sqlalchemy] finding if a table is already join in a query
What if your query already has a join yet you need to add another WHERE
clause to the join? This fails with This query already has a join for Table
xxx. Any way to modify your join to a query after you join it?

Hi Michael,
Thank you for the quick response.
Unfortunately we don't always know where this query comes from (my
example was a little contrived :( )
Is there any way to get the tables that are currently in the join for a
query?
You can iterate through q._from_obj(), and for each object that is a
join(), recursively descend through j.left and j.right looking for Table
objects. Table objects can be embedded in subqueries and alias objects
too but I'm assuming your query buildup here is simple enough that gray
areas like that aren't expected.
If it were me, I'd not be passing a raw Query around, I'd have it wrapped
inside a facade that is doing the abovementioned tracking of important state
explicitly (and also ensuring that those more grayish areas aren't occurring
with this particular Query). That way any other interesting facts about
the query as built so far can be tracked as well. Also easier to unit
test.
Here is a cut down sample implementation that will hopefully remove any
confusion... Note the TODO: in Employee.search()

[sqlalchemy] Re: Convert Declarative definitions to Table definitions
Ok, it was easier I thought with much thanks to the great __repr__() strings
that SQLAlchemy uses... made life so much easier
Here is the script I used, just pass the class object to the function and it
returns a string in table_name = Table(...) form.
Since this is just being used for sqlalchemy-migrate there is no need for
default or onupdate definitions, which contain function pointers in the
repr() anyways so they didn't work 100%

Re: [sqlalchemy] Checking the availablity of a booked Item
Here is an example of how I use outerjoin to perform a similar query. class Survey, def get_apps(self): Get all persons who are over 18 and do not have an appointment but have this survey. qry = Person.query.filter(Person.age 18) qry = qry.outerjoin((Appointment, (Appointment.id_person == Person.id) (Appointment.id_survey == self.id))). \ filter(Appointment.id == None) #: Or != None, depending on the type of join. #: I go and append a few more outer joins here as well,# but they look exactly the same just different tables.

# of course, end date must be after start date...
# Anyway you do it, your face isn't available for the period of time

start_date_cond = TimePeriod.start_date = time_period.end_date
end_date_cond = TimePeriod.end_date =
time_period.start_date
unavailable_periods =
Campaign.time_period.has(and_(start_date_cond,end_date_cond))
# I am not sure about what follows...
filter_cond = not_(unavailable_periods)
join_clause = Campaign.faces
return Face.query.filter(filter_cond).outerjoin(join_clause).all()
This code returns only faces that have already been booked before or have a
future booking, and are free for the moment. But faces with no bookings at
all are not returned. This may be due to an incorrect outerjoin ? (I also
tried a simple join with no success)
Here's the generated sql for one query :

[sqlalchemy] Column data representation
Is there a way to specify the way a column represents itself when converted to string? For example, I would like to automatically get all columns from table.c, and iterate over a record printing its fields. However when I come across a FK field, I would like to instead of printing out the integer value, query the database and print out the value from the referenced record. The key problem is I am getting my columns from table.c, so I don't know about the class mapper relationships that are defined. -- Thadeus -- You received this message because you are subscribed to the Google Groups sqlalchemy group.

[sqlalchemy] Easy way to referesh .__dict__
If I have a record object. me = Person.query.get(id) and I access me.__dict__ everything looks good. However when I execute a db.session.commit() the me.__dict__ disappears and only contains _sa_state_instance The second I access an attribute of the me instance, __dict__ comes back. What is the best way to always make sure the __dict__ instance is always populated with the object data without knowing any of the column names ahead of time ? -- Thadeus -- You received this message because you are subscribed to the Google Groups sqlalchemy group.
