I don't think the info I sent last night was particularly clear, apologies it was late. The code for the classes is below:
# ArkClient - clientprojectshot module orm.mapper(ArkClient, clients_table, properties={ 'contacts':orm.relation(ArkContact, backref='client'), 'projects':orm.relation(ArkProject, backref='client', cascade="all, delete, delete-orphan") }) # ArkProject - clientprojectshot module orm.mapper(ArkProject, projects_table, properties={ 'contacts': orm.relation(ArkContact, secondary=project_contact_table, backref='projects'), 'invoices':orm.relation(ArkInvoice, backref='project', cascade="all, delete"), 'shots':orm.relation(ArkShot, backref='project', cascade="all, delete, delete-orphan"), 'users':orm.relation(ArkUser, backref='projects', secondary=user_projects_primary_table) }) # ArkInvoice - invoices module orm.mapper(ArkInvoice, invoices_table, properties={ 'entries': orm.relation(ArkInvoiceEntry, secondary=invoice_entries_primary_table, backref='invoice', cascade="all, delete"), 'user': orm.relation(ArkUser, backref='invoice'), 'child_invoices':orm.relation(ArkInvoice, backref=backref('parent_invoice', remote_side=[invoices_table.c.id]), cascade="all", lazy=False, join_depth=3) }) What I am trying to do is query the client of an invoice, and to do this I need to build a query something along the lines of: invoice > project > client, and filter by client, or at least I thnk I need to do this. So the current query code I have looks something like this: invoices = query(ArkInvoice).\ join(ArkInvoice.project).\ join(ArkProject.client).\ options(sa.orm.contains_eager(model.ArkInvoice.project.client)).\ filter(model.ArkInvoice.project.client.id == id) But this doesn't work, and I've tried many variations around this theme with no joy. I'm clearly missing something fundamental, but I'm not sure what. Any pointers gratefully received.
