Approaching boost -> custom python class <-> serialize

[schoeller]

Dear all,

thanks for your opensource.

I am an occasional scripter and am trying to serialize a custom object from PyRx. I am banging my head doing as follows:

import traceback
from pyrx_imp import Ap, Db
from serialize import register_class
from serialize import dump, dumps

def textstyletablerecord_to_builtin(u): # take custom object and return python-builtin types
     return (u.getName())

def textstyletablerecord_from_builtin(c): # take python-builtin types and return custom object 
     tstr = Db.TextStyleTableRecord()
     tstr.setName(c[0])
     return tstr

register_class(Db.TextStyleTableRecord, textstyletablerecord_to_builtin, textstyletablerecord_from_builtin) # registering serialization class TextStyleTableRecord

@Ap.Command()
def jsontest():
    db = Db.curDb()
    tstr = Db.TextStyleTableRecord() # init the custom object
    print(tstr.className()) # output: AcDbTextStyleTableRecord

    tstr.setName("test") # setting name att
    dumps(tstr, fmt='yaml')

BTW className() prints AcDbTextStyleTableRecord. Also the modules PyRx established an intermediate interface





Then dumps throws as follows:

Exception has occurred: RuntimeError
Pickling of "PyDb.TextStyleTableRecord" instances is not enabled (http://www.boost.org/libs/python/doc/v2/pickle.html)

The custom object is generated in this (awesome) third party project using boost on different SDKs. I have seen a hint in the docs, but I am not sure whether this leads to anywhere or whether I should take a different path. Maybe I have just been stupid with class names.

Hints appreciated, I try to follow, but brain capacity is limited.

Regards

Seb

When trying a custom object like Ge.Point3d everythings works. It seems to have something to do with the boost pickle interface. For Ge.Point3d it is defined as boost::python::pickle_suite, but for Db.TextStyleTableRecord it is not. Is it possible to compensate this somehow within serialize?
