I am having a problem with finding the uploaded fileSize. Currently whe I use the file.read() function when I view the contents of the file after it is uploaded it is blank. Perhaps, someone can see what I am doing wrong. Here is my code: # I am passing the uploaded file, title, id .... REQUEST = context.REQUEST new_context = context.portal_factory.doCreate(context, id) # Generic editing method (ie. edits id + Metadata) new_context.plone_utils.contentEdit(new_context, id = id, title = title, ) spaceAvail = context.Availability() data = file.read() fileSize = len(data) if spaceAvail < 80: if fileSize < 30: sizeTest = context.getDirectories('/var/www/html/da') totalSize = fileSize + sizeTest if totalSize > 900: message = 'Failure: No available disk space, see system administrator' return ('failure', new_context,{'portal_status_message':message}) else: test = new_context.manage_editPloneExternalFile(title = title,file = file,REQUEST = REQUEST) if not test: return ('success', new_context,{'portal_status_message':context.REQUEST.get('portal_status_ message', 'Content updated.')}) else: return ('failure', new_context,{'portal_status_message':test}) else: errormsg = 'Failure: File exceeds size limitation of 30MB' return ('failure', new_context,{'portal_status_message':fileSize}) else: errormsg2 = 'Failure: No disk space available in /var directory' return ('failure', new_context,{'portal_status_message':errormsg2}) Thanks You.
