Can't set single canonical link of a post

Issue Summary

I believe #1388 created a possible issue where you can’t define your own canonical link of a post.

Steps to Reproduce

1. Set up a default instance of Ghost (with the default casper theme)
2. Create a new page
3. Under Post Settings > Code injection, add a canonical link to the page (ie <link rel="canonical" href="https://example.com/some-page">)
4. Check the source code. You now have two canonical links

This makes it impossible to set a canonical link. It makes it impossible to publish an article on another site, and republish it on your own, while still pointing to the first site as the original source.

Maybe I’m missing something (should I put the canonical link elsewhere?), but I can’t find it. It would be interesting to have a separate field for the canonical link.

Technical details:

• Ghost Version: 1.18.0 (using the Ghost-Azure fork)
• Node Version: 6.10.2
• Browser/OS: any
• Database: sqlite

Hey @petermorlion 👋 You’re correct, it’s not possible to change the canonical link for a post. This is a known limitation in Ghost, we’re aware of it and it’s on our internal feature tracking board as part of a larger meta overhaul.

As this is a feature request I’m going to close this issue as we use Github solely for bug tracking and on-going feature work.

We’ve added the ability to set a custom canonical url per post/page. Shipped in 2.17.0.
