Serve .md pages as Django views.

Project description

Django Markdown View

https://travis-ci.org/rgs258/django-markdown-view.svg?branch=master https://coveralls.io/repos/github/rgs258/django-markdown-view/badge.svg?branch=master

Serve .md pages as Django views.

This package aims to make it easy to serve .md files on Django sites.

Note

  • This package needs tests, and to have Travis and Coveralls properly configured.

Requirements

Tested with:

The Tested With section describes aspirational goals.

  • Python: 3.5, 3.6, 3.7, 3.8
  • Django: 2.2, 3.0

Note

  • Django 2.2 requires SQLite 3.8.3
  • Django 2.2 supports Python 3.5, 3.6, and 3.7.
  • Django 3.0 supports Python 3.6, 3.7 and 3.8.

We highly recommend and only officially support the latest release of each series.

Installation

  1. Install with pip install django-markdown-view.

  2. Add 'markdown_view' to your INSTALLED_APPS settings.

    INSTALLED_APPS = [
        ...,
        'markdown_view',
        ...
    ]
    
  3. (OPTIONAL) Add MARKDOWN_VIEW_BASE_DIR or BASE_DIR to settings

    The dictionary of the application’s base. See Settings below

    For example, if settings are in config/settings/base.py, then:

    BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))
    

Usage

Views

Use one of MarkdownView, LoggedInMarkdownView, or StaffMarkdownView from markdown_view.views to serve a .md file

from markdown_view.views import StaffMarkdownView

path('readme/',
    StaffMarkdownView.as_view(file_name='my_app/README.md'),
    name="readme"),

Settings

All settings are optional. See markdown_view/constants.py for the defaults.

  • MARKDOWN_VIEW_BASE_DIR and BASE_DIR

    When present, the value is taken as a location to append to the list of dirs that Django’s django.template.utils.get_app_template_dirs will return when passed dirname=””. This is used to locate .md files in the root of the project, e.g., a README.md file. Looks for BASE_DIR if MARKDOWN_VIEW_BASE_DIR is not found.

  • MARKDOWN_VIEW_LOADERS

    A list of loaders that locate .md files. The default list includes only markdown_view.loaders.MarkdownLoader which will by default try to load .md files from root directories in INSTALLED_APPS packages much the same as Django’s django.template.loaders.app_directories.Loader looks to load from “templates”.

  • MARKDOWN_VIEW_LOADER_TEMPLATES_DIR

    The name of the directories in INSTALLED_APPS packages in which to locate .md files. Defaults to “” in order to locate .md filed in the root directories.

  • MARKDOWN_VIEW_EXTENSIONS

    The extensions to enable. These extensions are enabled be default:

    • toc:
      generates a Table of Contents. If toc is removed from extensions, then MARKDOWN_VIEW_TEMPLATE_USE_TOC must be set to False.
    • tables:
      enables tables.
    • fenced_code:
      enables code blocks. If fenced_code is removed from extensions, then MARKDOWN_VIEW_TEMPLATE_USE_HIGHLIGHT_JS, which provides the highlighting for code blocks, can be disabled.
    • markdown_view.markdown_extensions.ImageExtension:
      makes images responsive in bootstrap4.

    See https://python-markdown.github.io/extensions/ and https://github.com/Python-Markdown/markdown/wiki/Third-Party-Extensions for more extensions.

    You can create your own extensions by following https://github.com/Python-Markdown/markdown/wiki/Tutorial-1—Writing-Extensions-for-Python-Markdown

  • MARKDOWN_VIEW_TEMPLATE

    The Django template that’ll be used to render the HTML that is generated from the Markdown. Set your own template to style your pages. Context includes:

    • markdown_content:
      The HTML produced from the Markdown.
    • use_highlight_js:
      If highlight.js is enabled.
    • use_toc:
      If the table of contents should be rendered.
    • markdown_toc:
      A table of contents from the headers of the Markdown. Not set when use_toc is False.
    • page_title:
      A guess at a page title, for now it’s the first row of the TOC. Not set when use_toc is False.
  • MARKDOWN_VIEW_TEMPLATE_USE_TOC

    Whether to render the TOC. If false, in the template context, use_toc is False and markdown_toc and page_title are not present.

  • MARKDOWN_VIEW_TEMPLATE_USE_HIGHLIGHT_JS

    Whether to load and activate the highlight.js library in the template.

Experimental Settings

  • MARKDOWN_VIEW_USE_REQUEST_CONTEXT

    If the request context should be used as a base when creating the context with which to render the Markdown internally. This is because the Markdown is rendered once first in order to prepend it with {% load static %}. This is not well tested; YMMV.

  • MARKDOWN_VIEW_EXTRA_CONTEXT

    Any extra context to send to the internal render of the Markdown. Can be used to expose context to template tags embedded in the Markdown. This is not well tested; YMMV.

Implementation

At a high level, MarkdownView will:

  1. Use a template loader to locate .md given as file_name
  2. Render as a template, the contents of the .md file prepended with {{% load static %}}, into several context variables
  3. Serve the MARKDOWN_VIEW_TEMPLATE with the context variables

Contributing

All contributions are very welcomed. Propositions, problems, bugs, and enhancement are tracked with GitHub issues and patches are submitted via pull requests.

We use Travis coupled with Coveralls as continious integration tools.
