Flask extension and Django App to add a nice blog to your website
Project description
Canonical blog extension
This extension allows you to add a simple frontend section to your flask app. All the articles are pulled from Canonical's Wordpress back-end through the JSON API.
This extension provides a blueprint with 3 routes:
- "/": that returns the list of articles
- "/": the article page
- "/feed": provides a RSS feed for the page.
How to install
To install this extension as a requirement in your project, you can use PIP;
pip install canonicalwebteam.blog
See also the documentation for (pip install)[https://pip.pypa.io/en/stable/reference/pip_install/].
How to use
Templates
The module expects HTML templates at blog/index.html, blog/article.html, blog/blog-card.html, blog/archives.html, blog/upcoming.html and blog/author.html.
An example of these templates can be found at https://github.com/canonical-websites/jp.ubuntu.com/tree/master/templates/blog.
Flask
In your app you can then:
import flask
from canonicalwebteam.blog import BlogViews
from canonicalwebteam.blog.flask import build_blueprint
app = flask.Flask(__name__)
# ...
blog_views = BlogViews()
app.register_blueprint(build_blueprint(blog_views), url_prefix="/blog")
You can customise the blog through the following optional arguments:
blog_views = BlogViews(
blog_title="Blog",
tag_ids=[1, 12, 112],
exclude_tags=[26, 34],
feed_description="The Ubuntu Blog Feed",
)
app.register_blueprint(build_blueprint(blog_views), url_prefix="/blog")
BlogExtension() accepts five parameters;
- (obj)
app - (str) "The title of your blog"
- (arr) Array of tags from blog entries on which to filter e.g
['1234', '4321'] - (str) Language string e.g.
"lang:en" - (str) "/path/to/display/your/blog"
Django
- Add the blog module as a dependency to your Django project
- Load it at the desired path (e.g. "/blog") in the
urls.pyfile
from django.urls import path, include
urlpatterns = [path("blog/", include("canonicalwebteam.blog.django.urls"))]
- In your Django project settings (
settings.py) you have to specify the following parameters:
BLOG_CONFIG = {
# the id for tags that should be fetched for this blog
"TAGS_ID": [3184],
# the title of the blog
"BLOG_TITLE": "TITLE OF THE BLOG",
# the tag name for generating a feed
"TAG_NAME": "TAG NAME FOR GENERATING A FEED",
}
- Run your project and verify that the blog is displaying at the path you specified (e.g. '/blog')
Groups pages
- Group pages are optional and can be enabled by using the view
canonicalwebteam.blog.django.views.group. The view takes the group slug to fetch data for and a template path to load the correct template from. - Group pages can be filtered by category, by adding a
category=CATEGORY_NAMEquery parameter to the URL (e.g.http://localhost:8080/blog/cloud-and-server?category=articles).
from canonicalwebteam.blog.django.views import group
urlpatterns = [
url(r"blog", include("canonicalwebteam.blog.django.urls")),
url(
r"blog/cloud-and-server",
group,
{
"slug": "cloud-and-server",
"template_path": "blog/cloud-and-server.html"
}
)
Topic pages
- Topic pages are optional as well and can be enabled by using the view
canonicalwebteam.blog.django.views.topic. The view takes the topic slug to fetch data for and a template path to load the correct template from.
urls.py
path(
r"blog/topics/kubernetes",
topic,
{"slug": "kubernetes", "template_path": "blog/kubernetes.html"},
name="topic",
),
Development
The blog extension leverages poetry for dependency management.
Regenerate setup.py
poetry install
poetry run poetry-setup
Testing
All tests can be run with poetry run pytest.
Regenerating Fixtures
All API calls are caught with VCR and saved as fixtures in the fixtures directory. If the API updates, all fixtures can easily be updated by just removing the fixtures directory and rerunning the tests.
To do this run rm -rf fixtures && poetry run pytest.
