Create Wagtail pages programmatically

This short recipe demonstrates how to create Wagtail pages programmatically. It may also be useful for testing Wagtail development against a reasonable volume of page data (about 35,000 film plots, from English Wikipedia).

Instructions

In a virtualenv:

kevinhowbrook

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.
