Incremental saving

[likage]

This is somewhat related to my batch process that I have posted but it is slightly different. I am trying to reuse some of the incremental saves script that I once used to have and have it implemented into use within the treeWidget and pushButton

Initially, I has something like this:

def importAndSave(self):
    root = self.ui.treeWidget_migrateAnm.invisibleRootItem()
    count = root.childCount()
               
    for i in range(count):
        item = root.child(i)
        ns = item.text(1)
           
        # For each item in list, it will be saved into each file
        # Have to force create a new scene
        cmds.file(f=True, new=True)
        cmds.file(rename= str(ns))
           
        # Import Rig commands

        # ....


       cmds.file(f=True, type='mayaAscii', save=True )

However the file saved directory is not what I had wanted, as I wanted it to be somewhere temporary and have it removed once the publishing fiasco is over...

I also noticed that in the event if I had multiple of the same items, since I am using the ns for the naming, I thought of adding in some sort of incremental values and tried changing the code to:

def importAndSave(self):
    root = self.ui.treeWidget_migrateAnm.invisibleRootItem()
    count = root.childCount()
           
    for i in range(count):
        item = root.child(i)
        ns = item.text(1)
       
        # Import Rig Commands
        # ....
       
        self.tmpSave()
       
def tmpSave(self):
    path = '/user_data/.tmp/anm_tmpFiles'
    newName = name + "_0001" + ".ma"
    newSaveDir = os.path.abspath(os.path.join(path))
    newSavePath = os.path.join(newSaveDir, newName)


    if os.path.exists(newSaveDir):
        savedFiles = os.listdir(newSaveDir)
        print savedFiles
        savedFiles.sort()
        incFiles = []
        for i in savedFiles:
            if fileName in i:
                incFiles.append(i)
        lastFile = incFiles[len(incFiles)-1]
        name = lastFile.partition(".")[0]
        newFileName = name[:-4]+(str(int(name[-4:])+1).zfill(4))+".ma"
        incSaveFilePath = os.path.join(newSaveDir, newFileName)
        system.saveAs(incSaveFilePath)

And this time round, I got the following traceback errors:

# Traceback (most recent call last):
#   File "/user_data/dev_test/anm/versions/anmTool_v02a.py", line 211, in test
#     self.tmpSave()
#   File "/user_data/dev_test/anm/versions/anmTool_v02a.py", line 232, in tmpSave
#     newSavePath = os.path.join(newSaveDir, newName)
#   File "/apps/Linux64/aw/maya2014/lib/python2.7/posixpath.py", line 66, in join
#     if b.startswith('/'):
# AttributeError: 'QString' object has no attribute 'startswith'

Or perhaps is there a better way to approach this?

It's hard to tell from the above code.  But I think newName = name + "_0001" + ".ma" is the source of your problem.  The var "name " is a QString object and not a python str.  The concatenation is returning another QString   So I think you should cast it to a string 1st,  str(name).

Hi there,

you are right. it seems to have bypass the error, never know about QString as I thought it will still work since it is still string..

However I have a problem in the "lastFile" line, especially so if there isn't a file to begin with.

For example, if there is already a "AvenueA_0001.ma" in the directory, it will automatically creates a "AvenueA_0002.ma" file, so on and forth. However say if I have a new file with the naming of "AvenueB", instead of creating "AvenueB_0001.ma", it will gives me the following error:

# Traceback (most recent call last):

#   File "/user_data/dev_test/anmg/versions/anmgTool_v02a.py", line 211, in test
#     self.tmpSave()
#   File "/user_data/dev_test/anmg/versions/anmgTool_v02a.py", line 246, in tmpSave
#     lastFile = incFiles[len(incFiles)-1]
# IndexError: list index out of range

Thats because you aren't checking your results after you list the directory contents, and then you are trying to index into an empty list:

       savedFiles = os.listdir(newSaveDir)
        print savedFiles
        savedFiles.sort()
        incFiles = []
        for i in savedFiles:
            if fileName in i:
                incFiles.append(i)
        lastFile = incFiles[len(incFiles)-1]

You have to handle the case where it is an empty directory.

Ah okay, damn I just found another problem.

Just when I thought it is increment-ing, it can only be incremented up to 0002 only, despite there is already a xxx_0002.ma within the directory.

The last file show is always 0001 instead of 0002. I was thinking if this is a hassle, I may as well just have the file save the with "row index" as it is listed within its QTreeWidget?

Will that be better or not practical?

I don't really know what to suggest right now, because your earlier pasted example seemed like pseudo code, since it contained a number of inconsistencies. Really only seeing fully working code is going to allow help with debugging. Obviously there is a right way to implement file name incrementing.
