Hi Marlin and Pavel, thanks for the response.
No, I'm not using super(). I can't find any documentation on this
class. Could you point me towards some? An example of what I mean is
below. The class below won't be able to create new rows in the admin
interface unless I comment out the three lines of the __init__ method.
It fails with an error like "class 'Company' requires three
arguements, only one given."
You want to do something like this:
class Company(DeclarativeBase):
__tablename__ = 'companies'
def __init__(self, name, company_symbol, **kwargs):
super(Company, self).__init__(**kwargs)
self.name = name
self.company_symbol = company_symbol
AFAIK, the DeclarativeBase constructor fills in attributes from kwargs
anyway, so you could get away with not using the constructor at all, and
simply creating new Companies like this:
company1 = Company(name='company', company_symbol='somesymbol')
class Company(DeclarativeBase):
__tablename__ = 'companies'
id = Column(Integer, primary_key = True)
name = Column(String, nullable = False)
company_symbol = Column(String)
def __init__(self, name, company_symbol):
self.name = name
self.company_symbol = company_symbol
def __repr__(self):
return "<Company('%s', '%s')>" % self.name,
self.company_symbol
Kind regards

Hi,
Could you please provide an example? Do you call superclass __init__
method in your class?

Hi there,
First off I want to say thank you to everyone that has spent their time
developing the TurboGears stack. It's great!
I have one question, or maybe it's a comment.
If you create your data models with '__init__' methods then the admin
interface is no longer able to add rows into the database. Is this by
design? I am just curious about the rationale and how it can be easily
changed.
Kind regards
Hansel
