Re: [moose-devel] Error in moose.connect method

[Subhasis R. <ray...@gm...>]

Hi,
  More specifically the error is due to incorrect field name, as the error
message suggests. The field name is 'spikeOut' and the snippet had not been
updated to reflect the change in naming.

Please note that we have settled on some naming conventions for fields
since async13 branch.
In particular, all source fields are suffixed 'Out' unless the field name
itself is output. Many of the old snippets and demos have been copied over
to the async13 branch but not yet updated to follow the new naming
convention and hence this error.

You can check the available field names using moose.doc() function in
Python which displays the class documentation and a list of fields, like
this:

>>> moose.doc('Compartment')

 If you want to display the documentation for a particular field, then
append the field name with a dot as separator:

>>> moose.doc('Compartment.Vm')

I made some fixes to docstring generation, so please update before reading
the docs.

Best,
- Subhasis
