Python - “NameError: name 'filename' is no

2019-09-25 08:32发布

Build mongoimport command

collection = filename[:filename.find('.')]  
working_directory = 'C:/Users/Anshuman Misra/Downloads/'  
json_file = filename + '.json'

mongoimport_cmd = 'mongoimport -h 127.0.0.1:27017 ' + \
                  '--db ' + db_name + \
                  ' --collection ' + collection + \
                  ' --file ' + working_directory + json_file

Before importing, drop collection if it exists (i.e. a re-run)

if collection in db.collection_names():  
    print 'Dropping collection: ' + collection
    db[collection].drop()

Execute the command

print 'Executing: ' + mongoimport_cmd  
subprocess.call(mongoimport_cmd.split())

Where did you define filename? You are using it on the first line but I don't see where it was defined.
