Lektor Atom Plugin
Builds one or more Atom XML feeds for your Lektor-based site.
Inspired by the atom-feed-support plugin Armin Ronacher wrote for the Lektor official blog.
Installation
Add lektor-atom-feed to your project from command line:
lektor plugins add lektor-atom-feed
See the Lektor documentation for more instructions on installing plugins.
Configuration
For each feed you want to publish, add a section to configs/atom.ini. For example, a blog with a feed of all recent posts, and a feed of recent posts about coffee:
[blog]
name = My Blog
source_path = /
url_path = /feed.xml
items = site.query('/').filter(F.type == 'post')
item_model = blog-post
[coffee]
name = My Blog: Articles About Coffee
source_path = /
url_path = /category/coffee/feed.xml
items = site.query('/blog').filter(F.categories.contains('coffee'))
item_model = blog-post
The section names, like blog and coffee, are just used as internal identifiers.
Options
| Option | Default | Description |
|---|---|---|
| source_path | / | Where in the content directory to find items' parent source |
| name | Feed name: default is section name | |
| filename | feed.xml | Name of generated Atom feed file |
| url_path | Feed's URL on your site: default is source's URL path plus the filename | |
| blog_author_field | author | Name of source's author field |
| blog_summary_field | summary | Name of source's summary field |
| items | None | A query expression: default is the source's children |
| limit | 50 | How many recent items to include |
| item_title_field | title | Name of items' title field |
| item_body_field | body | Name of items' content body field |
| item_author_field | author | Name of items' author field |
| item_date_field | pub_date | Name of items' publication date field |
| item_model | None | Name of items' model |
Customizing the plugin for your models
Use the field options to tell lektor-atom how to read your items. For example, if your site's model is:
[model]
name = Blog
[fields.writer]
type = string
[fields.short_description]
type = string
Then add to atom.ini:
[main]
blog_author_field = writer
blog_summary_field = short_description
See tests/demo-project/configs/atom.ini for a complete example.
Filtering items
By default, lektor-atom gets the source at source_path and includes all its children in the feed. If you set item_model, lektor-atom includes only the children with that data model.
Set items to any query expression to override the default. If items_model is also specified, lektor-atom applies it as a filter to items.
Use In Templates
You can link to a specific feed in your template. If your atom.ini contains a feed like this:
[main]
source_path = /blog
Link to the feed in a template like this:
{{ 'blog@atom/main'|url }}
