Flask extension to integrate discourse content generated to docs to your website.
Project description
canonicalwebteam.discourse
Flask extension to integrate discourse content generated to docs to your website. This project was previously named discourse_docs.
Writing documentation
Documentation for how to write documentation pages in Discourse for consumption by this module and how to configure the website to use the module can be found in the Canonical discourse.
Example Flask template for documentation pages can be found in examples folder. Please refer to the README in that folder for more information.
Install
Install the project with pip: pip install canonicalwebteam.discourse
You can add the extension on your project as follows, replacing, at least, base_url and index_topic_id with your own settings:
import talisker.requests
from canonicalwebteam.discourse import DiscourseAPI, Tutorials, TutorialParser
app = Flask("myapp")
session = talisker.requests.get_session()
discourse = Tutorials(
parser=TutorialParser(
api=DiscourseAPI(
base_url="https://forum.example.com/", session=session
),
index_topic_id=321,
url_prefix="/docs",
),
document_template="docs/document.html",
url_prefix="/docs",
)
discourse.init_app(app)
Once this is added you will need to add the file document.html to your template folder.
Local development
For local development, it's best to test this module with one of our website projects like ubuntu.com. For more information, follow this guide (internal only).
Running tests, linting and formatting
Tests can be run with Tox:
pip3 install tox # Install tox
tox # Run tests
tox -e lint # Check the format of Python code
tox -e format # Reformat the Python code
Instructions for Engage pages extension
Because you are viewing a protected topic, you must provide api_key and api_username. You also need an index topic id, which you can get from discourse.ubuntu.com. Your index topic must contain a metadata section. Visit the EngageParser for more information about the structure. You are encouraged to use an blueprint name that does not collide with existent blueprints. The templates must match the ones provided in the parameters indicated.
Here is an example of an implementation:
engage_pages = EngagePages(
api=DiscourseAPI(
base_url="https://discourse.ubuntu.com/",
session=session,
get_topics_query_id=14,
api_key=DISCOURSE_API_KEY, # replace with your API key
api_username=DISCOURSE_API_USERNAME, # replace with correspoding username
),
category_id=51,
page_type="engage-pages", # one of ["engage-pages", "takeovers"]
exclude_topics=[] # this is a list of topic ids that we want to exclude from Markdown error checks
additional_metadata_validation=[] # list of additional keys in the metadata table that you want to validate existence for e.g. language
)
In your project, you need to create your own views:
app.add_url_rule(
"/engage", view_func=build_engage_index(engage_pages)
)
app.add_url_rule(
"/engage/<path>", view_func=single_engage_page(engage_pages)
)
- Where
build_engage_indexwould be your view for the list of engage pages, which you can get by using the methodEngagagePages(args).get_index() - While
single_engage_pagewould be your single engage pages view, which you can get usingEngagePages(args).get_engage_page(path)
Similarly for takeovers, you just need to pass page_type="takeovers".
- To get a list of takeovers
EngagePages(args).get_index()also. - To get a list of active takeovers
EngagePages(args).parse_active_takeovers().
Pagination
get_indexprovides two additional argumentslimitandoffset, to provide pagination functionality. They default to 50 and 0 respectively.- If you want to get all engage pages, which in the case of some sites like jp.ubuntu.com there are not that many, you can pass
limit=-1 - Use
MaxLimitErrorin theexceptions.pyto handle excessive limit. By default, it will raise an error when it surpasses 500
