在 Solidworks PDM 库上运行 makepy 后缺少类方法

Question

I'm taking a crack at using the Solidworks PDM API to automate some file tasks. The first thing I did was run makepy.py on the PDMWorks Enterprise library as detailed here . This created a python file with a bunch of class definitions that I then renamed to "pdm_lib.py". The API defines a bunch of "interfaces" and "members," which in python seems to translate into "classes" and "methods". For example, this is what the IEdmVault5 class definition looks like:

class IEdmVault5(DispatchBaseClass):
    'IEdmVault5 Interface'
    CLSID = IID('{11AD8C69-12EA-4C9D-B20B-8C6D43B735AC}')
    coclass_clsid = IID('{AE784C6C-0155-11D3-B24B-0000F879F93B}')

    # Result is of type IEdmStrLst5
    def BrowseForFile(self, hParentWnd=defaultNamedNotOptArg, lEdmBrowseFlags=8, bsFilter='', bsDefaultExtension=''
            , bsDefaultFileName='', bsDefaultFolder='', bsCaption=''):
        'method BrowseForFile'
        return self._ApplyTypes_(22, 1, (9, 32), ((3, 1), (3, 49), (8, 49), (8, 49), (8, 49), (8, 49), (8, 49)), 'BrowseForFile', '{AAFEA179-C9AE-4032-81C4-2AFCAA67B81A}',hParentWnd
            , lEdmBrowseFlags, bsFilter, bsDefaultExtension, bsDefaultFileName, bsDefaultFolder
            , bsCaption)

    # Result is of type IEdmFolder5
    def BrowseForFolder(self, hParentWnd=defaultNamedNotOptArg, bsMessage=defaultNamedNotOptArg):

        except pythoncom.error:
            raise TypeError("This object does not support enumeration")
        return win32com.client.util.Iterator(ob, None)

Here's a simple bit of code I wrote that connects to a file vault and checks out a file:

from pdm_lib import *
folder_path = 'C:\\Logos_Production\\vendors\\mcmaster-carr\\test\\'
file_path = 'C:\\Logos_Production\\vendors\\mcmaster-carr\\test\\1019A12.SLDPRT'

username = 'username'
pw = 'pw'
vault_name = 'vault_name'

vault = EdmVault5()
vault.Login(username, pw, vault_name)
folder = vault.GetFolderFromPath(folder_path)
file = vault.GetFileFromPath(file_path, folder)[0]
file.LockFile(folder.ID, file.CurrentVersion)

The problem I'm running into is that when I try to use the "IEdmBatchUnlock" interface. According to the API documention , the following "members" (methods) should be available for it:

• AddSelection
• CreateFileTree
• GetFilelist
• ShowDlg
• UnlockFiles

Here's my attempt to create an IEdmBatchUnlock and call the "AddSelection" method:

from pdm_lib import *

username = 'username'
pw = 'pw'
vault_name = 'vault'

vault = EdmVault5()
vault.Login(username, pw, vault_name)

unlocker = logos_prod.CreateUtility(6)
unlocker.AddSelection(vault, selected_items)

I've also tried to do the same using late binding:

from win32com.client import Dispatch

username = 'username'
pw = 'pw'
vault_name = 'vault'

vault = win32com.client.Dispatch('ConisioLib.EdmVault.1')
vault.Login(username, pw, vault_name)

unlocker = logos_prod.CreateUtility(6)
unlocker.AddSelection(vault, selected_items)

Both sets of code appear to successfully create a "IEdmBatchUnlock" object, but In both cases I get the same "object has no attribute 'AddSelection'" error when I attempt to run the "AddSelection" method. When I look at the class definition in pdm_lib.py, this is all I see:

class IEdmBatchUnlock(DispatchBaseClass):
    'IEdmBatchUnlock Interface'
    CLSID = IID('{748E6759-E16D-4F69-A0BC-98A9A9F2E650}')
    coclass_clsid = None

    _prop_map_get_ = {
        "Comment": (5, 2, (3, 0), ((16392, 10),), "Comment", None),
    }
    _prop_map_put_ = {
        "Comment": ((5, LCID, 4, 0),()),
    }
    def __iter__(self):
        "Return a Python iterator for this object"
        try:
            ob = self._oleobj_.InvokeTypes(-4,LCID,3,(13, 10),())
        except pythoncom.error:
            raise TypeError("This object does not support enumeration")
        return win32com.client.util.Iterator(ob, None)

I don't see any reference to any of the aforementioned methods here, or anywhere else in pdm_lib.py, so I'm not surprised that when I call the AddSelection method on an IEdmBatchUnlock object, python throws an error. Any suggestions on how I can get this working in Python?

*EDIT: Updated my post for clarity

Answer 1

If you go to IEdmBatchUnlock interface page under accessors you will see IEdmVault7::CreateUtility .

You are not supposed to create it directly.

Answer 2

I ultimately solved this problem in two separate ways:

1. Dynamic Dispatch in win32com
2. Generating module using comptypes

Option 1 Code:

import comtypes.client as cc
cc.GetModule('C:\Program Files (x86)\SOLIDWORKS PDM\EdmInterface.dll')
import comtypes.gen._5FA2C692_8393_4F31_9BDB_05E6F807D0D3_0_5_22 as pdm_lib2

vault = cc.CreateObject('ConisioLib.EdmVault.1')
vault.LoginAuto(vault_name, 0)

Option 2 Code:

import win32com.client
vault = cc.CreateObject('ConisioLib.EdmVault.1')
vault.LoginAuto(vault_name, 0)

When I created the vault objects this way (and then called the utility method to create the unlocker), I was able to access the "AddSelection" method. Not sure why this worked and makepy.py didn't, but I'm not an expert on COM objects
