using arcpy.env.workspace to open a MXD

JohnNerge — Mon, 18 Jun 2012 14:59:06 GMT

So my script was working on Friday but doesn't anymore, and I can't figure out why. Basically, I am running into an error when trying to set the environment workspace and use it to open a MXD. Here is a dumbed down version of the piece of my code that is throwing an error (it throws the same error as what's in my actual code:

import arcpy

arcpy.env.workspace = "C:/test"

mapdoc = "test.mxd"

mxd = arcpy.mapping.MapDocument(mapdoc)

and here is the error:
>>> Traceback (most recent call last):
File "C:\Python26\ArcGIS10.0\Lib\site-packages\pythonwin\pywin\framework\interact.py", line 558, in OnEditExecClipboard
exec o in __main__.__dict__
File "<clipboard>", line 7, in <module>
File "C:\Program Files (x86)\ArcGIS\Desktop10.0\arcpy\arcpy\arcobjects\mixins.py", line 443, in __init__
assert (os.path.isfile(mxd) or (mxd.lower() == "current")), gp.getIDMessage(89004, "Invalid MXD filename")
AssertionError: Invalid MXD filename.

If I run arcpy.mapping.MapDocument("C:/test/test.mxd") it works fine, so I don't know where things are getting hung up. Please help, and thanks in advance to all for any input.

It requires the full path. The MapDocument object does not respect workspaces.

Mathew,

Thanks, I guess I must have changed something about that between today and Friday, though for the life of me I don't really think I did.
