Enterprise Architect：GetBaselines 在 python 中不起作用

Question

我编写了一个 Python 函数来从 PackageGUI 中检索基线：

def get_baselines(pkgguid):
    """ Get list of baselines for package """
    rep = win32com.client.Dispatch("EA.App").Repository
    rep.GetPackageByGuid(pkgguid) # Works
    print("pgkname: ", pkg.Name) # This works
    project = rep.GetProjectInterface() # Works
    print ("guid xml: ", project.GUIDtoXML(pkgguid), "GUID: ", pkgguid) # Works
    pkgxml = project.GetBaselines(project.GUIDtoXML(pkgguid)) # Throws Error
    print (pkgxml) # Not reached

这会导致错误：

File "C:\devel\EnterpriseArchitect\ea_scripts\dbops.py", line 44, in get_baselines
pkgxml = project.GetBaselines(project.GUIDtoXML(pkgguid))
File "<COMObject GetProjectInterface>", line 3, in GetBaselines
pywintypes.com_error: (-2147352571, 'Type mismatch.', None, 1)

我之前没有使用过任何Project Interface，所以可能是输入格式有误？

project.GetBaselines接受两个String类型的参数，而你只传递了一个参数。
参见 the documentation

GetBaselines (string PackageGUID, string ConnectString)

String

Notes: Returns a list (in XML format) of Baselines associated with the supplied Package GUID.

Parameters:

PackageGUID: String - the GUID (in XML format) of the Package to get Baselines for

ConnectString: String - not currently used

所以你需要这样称呼它：

pkgxml = project.GetBaselines(project.GUIDtoXML(pkgguid), "")
