Params

Name
Description
type Symbol

answer Hash
Required. The answer, that varies depending on the type defined, read about the response formats for each type on Telegram documentation.

Usage

When an inline query arrives, the configured context will handle it, through action blocks that capture text messages such as keyword, intent, entity, any_text and so on.
In the next example, we've created a context called NewsContext, which has been configured to handle inline queries as follows:
config.routes.inline_query = :news
This context will call two keyword blocks with the arguments "nytimes" and "cnn" respectively. Each of them will return news extracted from the RSS service from the The New York Times or CNN.
class NewsContext < Conversation
def blocks
keyword "nytimes" do
feed_entries("https://rss.nytimes.com/services/xml/rss/nyt/World.xml")[0..10].each do |article|
@reply.inline_query_result(
:article,
{
title: article.title,
description: article.summary.to_s,
url: article.url,
thumb_url: article.image.to_s,
photo_width: 128,
photo_height: 128,
input_message_content: {
message_text: @reply.render_html_template(:news, :preview, {article: article}),
parse_mode: "HTML"
}
}
)
end
end
keyword "cnn" do
if @msg.type == :inline_query
feed_entries("http://rss.cnn.com/rss/edition_world.rss").each do |article|
@reply.inline_query_result(
:article,
{
title: article.title,
description: article.summary.to_s,
url: article.url,
thumb_url: article.image.to_s,
photo_width: 128,
photo_height: 128,
input_message_content: {
message_text: html_template("news/preview", {article: article}),
parse_mode: "HTML"
}
}
)
end
else
@reply.text "This example only works in Inline Mode for Telegram"
end
end
end
protected
def feed_entries(url)
xml = HTTParty.get(url).body
feed = Feedjira.parse(xml)
return feed.entries
end
end
To implement this example you'll need to add the gems feedjira and httparty to the project's Gemfile.

In the example above, html_template("news/preview", {article: article}) has been called, this method loads a template from bot/templates/news/preview.rhtml with the following code:
<b><%=article.title%></b>
<i><%=article.summary.to_s.truncate(50)%></i>
<a href="<%=article.url%>"> Read more </a>
