- 1.3 post excerpt migration
- add 1.3 migration to add `excerpt` to post schema
NOTE:
- knex-migrator relies on the package.json safe version
- so right now Ghost is on 1.2
- the migration script is for 1.3
- if you pull down the PR (or if we merge this PR into master), you have to run `knex-migrator migrate --v 1.3 --force`
- knex-migrator will tell you what you have todo
- Bump dependencies
- knex-migrator@2.1.3
- Soft limit for custom_excerpt
- Extended {{excerpt}} to use custom excerpt
- when a `custom_excerpt` field exists, the `{{excerpt}}` helper will output this and fall back to autogenerated excerpt if not.
- Refactored behaviour of (meta) description
- html tag `<meta name="description" />` for posts, tags and author doesn't get rendered if not provided.
- fallback for `author.bio` removed
- fallback for `tag.description` removed
- structured data and schema.org for `post` context takes the following order to render description fields:
1. custom excerpt
2. meta description
3. automated excerpt (50 words)
- updated and added tests to reflect the changes
