Urls registered under same endpoint name

[jrcastro2]

Comment/shelve: Since we are still in setup mode at this point, isn't it possible to use current_app.add_url_rule here like before? I suspect it's because of this check. Which is a valid check in the sense that if you did url_for("invenio_pages.view"), you would probably get a random URL back?

In any case, I think the best would be to have unique human-friendly endpoint names for each page rule and point them all to the invenio_pages.views.view function. But this unique key is not currently part of the Page model, so that would mean opening a can of worms and updating the alembic recipes, etc.

The above also means that there's no way to do something like url_for("about_page") to get the URL for a page.

So maybe we just open an issue and revisit in the future to add this as a feature.

Decision:

• invenio-pages should not register any dynamic URLs/route
• invenio-pages should provide a helper to render a page, given a URL
• Overlays should declare blueprints that will render each specific page
• Provide documentation
