CSV Processor

Project description

PyPI CI Codecov Documentation Supported Python versions License

Generic CSV Processing for Django Apps


This library provides a CSVProcessor class which should be subclassed to implement your own per-row processing of CSV files. At minimum, override process_row(row).

The mixins support optional checksums of arbitrary columns, and asynchronous processing of files using Celery.


Super CSV is a stand alone library that can be used for CSV management, both syncronous and async.


make requirements

Will install all prerequisites.

make test

Runs the unit tests in local environment.

Using with Docker Devstack

Prerequisite: Have your Open edX properly installed. Note: When you see “from inside the lms” below, it means that you’ve run make lms-shell from your devstack directory and are on a command prompt inside the LMS container.

  1. Clone this repo into ../src/ directory (relative to your “devstack” repo location). This will mount the directory in a way that is accessible to the lms container.

  2. Clone inside the lms, uninstall super-csv and reinstall your local copy. You can run the following line from inside the lms, or from the host machine run make install-local. This is necessary if one wants to use latest version for testing/development purposes:

    pip uninstall super-csv -y; pip install -e /edx/src/super-csv
  3. Setup dev environment (since virtual environments are recommended for python development, here is an example of using virtualenv. Other tools would work as well). By default, edx containers come with virtualenv preinstalled

    cd /edx/src/super-csv
    virtualenv super-csv-env
    source super-csv-env/bin/activate
    make requirements
  4. That’s it.
