DIKU support tools for Canvas LMS
Project description
These tools leverage the Canvas LMS REST API to create a more pleasant environment for working with Absalon.
“Staffeli” is Danish for “easel” — a support frame for holding up a canvas.
1 Purpose
The purpose of Staffeli is two-fold:
Leverage the Canvas LMS REST API to get things done better, faster, stronger.
Quick prototyping of new features for Canvas LMS.
Initially, Staffeli is not intended for managing course content, merely to snapshot course data (e.g. enrolled students, groups, sections, submissions), and to get grading done efficiently.
Although Staffeli is written in Python 3, it is not intent on forcing you to manage your course using Python, or to have to get intimate with the Staffeli API to get things done. Staffeli extensively uses YAML files for storage, enabling the easy use of both command-line utilities and the programming language of your choice, to get things done quickly, and efficiently.
2 Status
Staffeli is maturing. It is being transitioned to be annotated with type hints, with the types checked statically with mypy, and a test-suite has been set up, but full-blown continuous integration remains to be set up.
We are still covering a fairly small subset of the API. Brace yourself. Lend a hand.
3 Installation
Clone, or download this repository.
pip3 install -e .
4 Getting Started
With Staffeli, we work with local course clones. We aim to keep these clones compatible with git.
We recommend that you create a local directory canvas, absalon, or similar, for all of you Canvas-related local course clones. Staffeli needs some initial help to be able to login with your credentials. You need to generate a token for Staffeli to use, and save it as .token, token, or token.txt in this high-level directory.
NB! This is your personal token so do not share it with others, else they can easily impersonate you using a tool like Staffeli. Unfortunately, to the best of our knowledge, Canvas has no means to segregate or specialize tokens, so this is really “all or nothing”.
4.1 Cloning a Course
To clone a course:
$ staffeli clone <course name>
The <course name> may be a substring of the course name as it appears on your dashboard. Casing is not important. If there are multiple conflicting names, or no matching course names, Staffeli will complain and let you try again.
4.2 Fetch Submissions for a New Assignment
Use staffeli fetch. For instance, to fetch all submissions for “A3”:
$ staffeli fetch subs/A3
To fetch just the metadata for all submissions, but not the submissions themselves:
$ staffeli fetch subs
4.3 Fetch Groups
This is a good idea to make sure you are up-to-date with canvas.
$ staffeli fetch groups
4.4 Split According to Some Group Category
Assuming you already fetched groups and submissions,
$ staffeli groupsplit subs/A3 groups/Team.yml
4.4.1 NB
If you are using git to share course internals, remember to push both changes to `groups <groups>`__, `subs <subs>`__, and `splits <splits>`__, when making splits for some new assignment.
4.5 Grade a Submission
Assuming you are in the submission directory, you can use staffeli grade to grade the submission:
staffeli grade GRADE [-m COMMENT] [FILEPATH]... Where GRADE pass, fail, or an int. [-m COMMENT] An optional comment to write. [FILEPATH]... Optional files to upload alongside.
5 Documentation
It is up-and-coming on [ReadTheDocs](http://staffeli.readthedocs.io/en/latest/). The source files for that page are under [docs/source](docs/source), and they are, much like this README, written in reStructured Text. It is also suggested to follow the Python documentation style guide.
6 Contributing
First, take a look at our design guide and style guide.
Contact us at dikunix at dikumail dot dk.
Take a look at our on-going issues.
7 Testing
Currently, Travis CI will only check that you roughly conform to the PEP 8 Python Style Guide (using flake8), and perform static type-checking with mypy, all only for selected Python files in this repository. See (and run?) `static_tests.py <static_tests.py>`__ for further details.
Before you do that however, you might want to do this:
$ pip3 install -r test-requirements.txt
This will also install what you need to run the dynamic tests we have in store under tests, except for Docker: `start_local_canvas.py <start_local_canvas.py>`__ will fire up a Docker image with a local Canvas instance for use with our tests. You will also find it in your browser under the address localhost:3000. The user is canvas@example.edu and the password is canvas.
The static and dynamic tests are also part of the `pre-commit <hooks/pre-commit>`__ and `pre-push <hooks/pre-push>`__ hooks, respectively. Install these hooks by executing `hooks/install.sh <hooks/install.sh>`__. Unfortunately, neither these hooks, nor the hooks installer will work on Windows.
7.1 Static Testing Framework
We use flake8 for style-checking and mypy for static type-checking.
Assuming you have these tools installed, you can do this:
$ ./static_tests.py
This is also part of the `pre-commit <hooks/pre-commit>`__ hook.
7.2 Dynamic Testing Framework
We use pytest together with hypothesis.
Assuming you have these tools installed, you can do this:
$ pytest
This is also part of the `pre-push <hooks/pre-push>`__ hook.
7.3 Dynamic Test Coverage
Run pytest with the option --cov=staffeli to get an idea of the test coverage of Staffeli proper.
It is pretty lousy ATM. As of 2017-05-16, the numbers were:
