Can not save vsdx

[Kranfield]

Hello,

When I try to save a vsdx (with vis.save_vsdx("vsdx_file_name_here") I edited with a python script, I have this error :

Traceback (most recent call last):

  File "C:\Spyder\Python\Python310\lib\xml\etree\ElementTree.py", line 762, in _get_writer
    write = file_or_filename.write

AttributeError: 'str' object has no attribute 'write'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

  File "C:\Users\qbernard\Desktop\PythonTestsScripts\VisioUpdater\script\main.py", line 357, in <module>
    vis.save_vsdx('vsdxfile.vsdx')

    file = open(file_or_filename, "w", encoding=encoding,

FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\qbernard\\Desktop\\PythonTestsScripts\\VisioUpdater\\script\\MVS_BASELINE20220927/visio/pages/_rels/pages.xml.rels'

Right now I am not sure why the "file is not found", since when I open my vsdx as a zip, in /MVS_BASELINE20220927/vision/pages/_rels, i find the pages.xml.rels. I was guessing it is because of the \ and / in the path, but I prefer to ask here (maybe I did a stupid error and I did not see it...)

my main section of code :

if __name__ == '__main__' :
    """

    """

    pathVis = 'C:/Users/qbernard/Desktop/PythonTestsScripts/VisioUpdater/script/MVS_BASELINE20220927.vsdx'
    vis,pathVis = openVis(pathVis = pathVis)
    extractToDatabase(vis = vis, pathVis = pathVis)

    dataset = restruct(database)
    dataset = keySave(dataset)
    dataset_001 = AdvQuery(dataset, "ID", ["VAR"])
    dataset_001 = AdvQuery(dataset_001, "Nom ADL1", ["Nom ADL1"]) # Testing Purposes
    batchRewrite(dataset_001, "Nom ADL1", "Nom_ADL1") # Testing Purposes
    print("DEBUG : Importing to Visio")
    importDatabaseToVis(database, vis = vis, pathVis = pathVis)
    pathVis02 = vsdxSaveAs() # this open a save as window, we overwrite the vsdx file.
    vis.save_vsdx('pathVis02')

Any guess where this error can come from ?

Yours,

Quentin

Ok so after a week, I found why it was not working. It seems that the saving process is not opening the file so you have to open it before and keep it open. Maybe it would be great to add a functionnality that detect whether the file is open or not, and will open it in write mode if it is not the case.

Hi @Kranfield - I guess in your OpenVis() method you are either processing the vsdx file in a with block or explicitly closing it, so the vis object has all the data from the vsdx file but after it's closed the folder structure is removed so we get this error.

I hadn't considered this use case before - but I can see it being really useful. Ideally the original vsdx file contents will be incorporated into the VisioFile object so it can still reconstruct the file structure in save_vsdx() whether still open or not.

Let me have a look into that and feedback here
