While setting up Views RSS so that I can use Mailchimp on Poligo, I came across this good guide to using fields for RSS.
Points to be wary of:
- For the <link> element, use
"content: path"and in field configuration section (Rewrite results fieldset) check
Use absolute link (begins with "http://");
- The element <author> should contain the author’s email address. In D7 and D8, start with adding
Content: Authorrelationship. Use field
User: Email. In field configuration section: in
Link this fieldselect
- <Category> should be
Content: All taxonomy terms. The manual recommends “in the field configuration section D7, in
RSS <category> element“, but this was not available.
- For <GUID> use
UPDATE: I found a much easier way to acheive what I want. There is an RSS display for each content type. Creating an RSS feed view of content, and then choosing what I wanted in admin/structure/types/manage/blog/display/rss did the business. The ony issue now is image size in the RSS reader.
