[Pyobjfs-users] Problems running tutorial

[Stephen R. F. <fi...@mo...>]

I was playing around with oops, attempting to follow the tutorial:

  http://pyobjfs.sourceforge.net/tutorial.html

I am using Python 2.2 on a Redhat 7.2 Linux install.  Oops 0.9.1

My first snag in the Medical patient example was Date, which Python
said wasn't defined.  I checked the API and noticed there was no Date
type (or Class, rather) so I took a guess and changed it to Data()

Then I got a complaint about Obj.__init__

>>> patient_db.append(Patient("Dan", "Parisien", (5,5,1980)))
Traceback (most recent call last):
  File "<pyshell#48>", line 1, in ?
    patient_db.append(Patient("Dan", "Parisien", (5,5,1980)))
  File "<pyshell#46>", line 8, in __init__
    Obj.__init__(**kwargs) # OOPS uses keyword arguments TypeError:
unbound method __init__() must be called with Obj instance as first
argument (got nothing instead)

hmmm... okay, so I took a stab at this perhaps being 

  Obj.__init__(self, **kwargs)

>>> patient_db.append(Patient("Dan", "Parisien", (5,5,1980)))
Traceback (most recent call last):
  File "<pyshell#51>", line 1, in ?
    patient_db.append(Patient("Dan", "Parisien", (5,5,1980)))
  File "/usr/lib/python2.2/site-packages/oops/core.py", line 1372, in append
    value.__moveto__(self.__database__, self.__path__+(key,), self)
  File "/usr/lib/python2.2/site-packages/oops/core.py", line 615, in __moveto__
    Node.__moveto__(self, database, path=(), parent=None)
  File "/usr/lib/python2.2/site-packages/oops/core.py", line 216, in __moveto__
    getattr(self, key).__moveto__(database, path+(key,), self)

    for key in list.__iter__(self):
AttributeError: type object 'list' has no attribute '__iter__'



Some sort of problem with list?  The tests seemed to run okay:

[fig@localhost oops-0.9.1]$ python2 test.py
............
----------------------------------------------------------------------
Ran 12 tests in 26.973s

OK

Do you have any advice?

[Pyobjfs-users] Fix for exception in test suite (under Windows 2000)

[Hamish L. <hb...@st...>]

The following exception gets raised when running the tests under Windows
2000:

Traceback (most recent call last):
  File "testsuite\objtests.py", line 29, in runTest
    os.remove("myfile.obj")
OSError: [Errno 13] Permission denied: 'myfile.obj'

I believe the problem is that a file handle is still open at the time that
the file is being removed. The fix is to delete obj beforehand:

Compare: (<)E:\temp\oops-0.9\testsuite\objtests.py (1407 bytes)
   with: (>)E:\temp\oops-0.9\testsuite-new\objtests.py (1423 bytes)

>         del obj
