[help] Summary says "No details available"

[hentai_dude]

Hi, I'm Hentai_dude who just recently bought a Kindle device and I'm not familiar with programming.

I tried to send a news feed to my Kindle using the Calibre feature, but the summary does not appear under the headline of the article, instead it says "No details available".
I would like to have the summary of the article displayed there.

I searched using the great Google engine and found several people here and there with similar problems.

I think the reason it is not displayed properly is because the "description" field in the RSS feed is blank.

After two days of trial and error, I was able to get to the point where I could change the display of the relevant section by changing the "text_summary".

Like this:

    def populate_article_metadata(self, article, soup, first):
        article.summary = article.text_summary = 'Hentai dude testing'

But what I really want my Kindle to display is not "Hentai dude testing" but a summary of the article.

Any help would be greatly appreciated!

This is my recipe, just in case:

from calibre.web.feeds.news import BasicNewsRecipe

class Sankei(BasicNewsRecipe):
    title          = 'Sankei'
    oldest_article = 2
    max_articles_per_feed = 100
    auto_cleanup   = True

    feeds          = [
        ('社会', 'https://assets.wor.jp/rss/rdf/sankei/affairs.rdf'),
        ('政治', 'https://assets.wor.jp/rss/rdf/sankei/politics.rdf'),
        ('経済', 'https://assets.wor.jp/rss/rdf/sankei/economy.rdf'),
        ('国際', 'https://assets.wor.jp/rss/rdf/sankei/world.rdf'),
        ('スポーツ', 'https://assets.wor.jp/rss/rdf/sankei/sports.rdf'),
        ('エンタメ', 'https://assets.wor.jp/rss/rdf/sankei/entertainments.rdf'),
        ('ライフ', 'https://assets.wor.jp/rss/rdf/sankei/life.rdf'),
    ]

Your RSS feeds dont have summaries so the recipe cannot get them from there. Instead you will need to scrape the actual article page not just the rss feed, for information on how to do that, see https://manual.calibre-ebook.com/news.html

but note that this will require some programming.

It was helpful just to know that I can't use these RSS feeds to get information about summary. Good to avoid spending another few days on impossible things!
