pipenv for function/code completion

When using vagrant, vscode won't be able to map to the vm, well not yet anyway. A way around this is to checkout a branch called pipenv, run pipenv --python 3 to create a virtual environment. Then run pipenv install -r requirements.txt to install everything in the project.

After doing this, in vscode ctrl+p then search for >python: select interpreter. Select the virtual env python, it will look something like this: /home/yourname/.local/share/virtualenvs/project-foo-JbRjzqlX/bin/python.

Just don't commit the pipenv stuff.

How to test a class method using mock:

You can patch the entire requests module with:

@mock.patch('requests.get')

But it's better to keep it specific as per:

@mock.patch('rca.shortcourses.access_planit.requests.get')
