Hello,
I would like to be able to make a base class that has some columns, and
subclass that base class so I can inherit those columns, for example:
import tables
class A(tables.IsDescription):
x = tables.Int32Col()
class B(A):
y = tables.Int32Col()
inFile = tables.openFile('test.h5', mode="w")
group = inFile.createGroup(inFile.root, 'group')
table = inFile.createTable(group, 'table', B, 'a table')
entry = table.row
print '\n', '*' * 20, 'column names', table.colnames, '*' * 20, '\n'
entry['y'] = 0
entry['x'] = 1
inFile.close()
When I run it I get this:
cswank-09290s:test cswank$ python blah.py
******************** column names ['y'] ********************
Traceback (most recent call last):
File "blah.py", line 18, in <module>
entry['x'] = 1
File "tableExtension.pyx", line 1294, in tableExtension.Row.__setitem__
File "tableExtension.pyx", line 130, in tableExtension.getNestedFieldCache
File "utilsExtension.pyx", line 375, in utilsExtension.getNestedField
KeyError: 'no such column: x'
Closing remaining open files: test.h5... Done
Is there a way to inherit columns from a superclass?
Thanks,
Craig
