Odoo 14.0 — Multi-Website Blog Filter

Fixes a behavioral gap in Odoo 14 Community's multi-website blog setup: the "All" blog view (/blog) normally returns posts from every website, ignoring website boundaries. This module overrides the blog controller to scope all blog views — the "All" listing, individual blogs, post detail, and tag views — to the current website context.

---

The Problem

In a standard Odoo 14 multi-website installation:

• Individual blogs can be assigned to specific websites via the website_id field on blog.blog
• Blog posts inherit their website from their parent blog
• However, the /blog ("All") route returns posts from every website regardless of which site the visitor is on

This module corrects that behavior without any schema changes or data migrations.

What It Does

Route	Behavior
/blog	Shows only posts from blogs assigned to the current website, plus blogs with no website (shared/global)
/blog/<blog>	Accessible only if the blog belongs to the current website (or has no website set); returns 404 otherwise
/blog/<blog>/<post>	Same access check as above, plus validates the post belongs to that blog
/blog/<blog>/tag/<tag>	Tag filtering within a website-scoped blog view

Shared blogs: Any blog.blog record with no website_id set will appear on all websites. This allows truly global content alongside site-specific blogs.

Controller Overview (controllers/main.py)

WebsiteBlogMultiWebsite extends Odoo's core WebsiteBlog controller:

• _get_website_blogs() — helper that returns blogs matching the current website, plus blogs with no website set
• _check_blog_access(blog) — helper that validates a specific blog is accessible from the current website
• blog() — overrides /blog and /blog/page/<n>; builds a filtered post domain and renders website_blog.blog_post_short with website-scoped data
• blog_post() — overrides /blog/<blog> individual blog routes; applies access check then delegates to parent
• blog_post_detail() — overrides /blog/<blog>/<post>; checks blog access and post/blog relationship, then delegates to parent
• blog_tag() — overrides tag routes; applies blog access check, then delegates to parent

All overridden methods include exception handling that falls back to the parent controller on unexpected errors, with logging via _logger.

Notes

• __pycache__/ directories are generated at runtime — add them to .gitignore
• Developed and tested against Odoo 14.0 Community
• The price and currency fields have been removed from the manifest (they are not standard Odoo Community fields)
• This addresses a core behavioral gap that may be handled differently in later Odoo versions
