我正在尝试遍历 Atom 提要中每篇文章的图片。我有以下代码可以很好地呈现 Atom 提要,但不确定这些是否是正确的图像标签。
任何关于最佳设置的建议都是惊人的。
这将呈现下面的 XML;index.atom.builder:
atom_feed do |feed|
feed.title "posts"
feed.updated @articles.maximum(:updated_at)
@articles.each do |article|
feed.entry(article) do |entry|
entry.title article.title
entry.content(article.body, type: 'html')
entry.author do |author|
author.name article.author
if article.pictures.any?
article.pictures.each do |pic|
entry.logo image_tag pic.photo.url(:large)
end
end
end
end
end
end
XML 输出:
<?xml version="1.0" encoding="UTF-8"?>
<feed xml:lang="en-US" xmlns="http://www.w3.org/2005/Atom">
<id>tag:HEROKU APP:/articles</id>
