After Maja did add a more advance OneBox for Amazon links I would like to know if it is possible to “hack” the OneBox to strip more chars so the Onebox gets bigger. [image] Import data from e.g Amazon like ISBN etc (A extended onebox solution for Amazon) Feature I would like to add a book review section at my site. One box does some of the job like: But is it possible to “hack” to a form like this? Image Title: Author: ISBN: Book description: Star rating from Amazon Eg I see the max chars for description is 200 chars. Where can I change that? Then I could have a larger OneBox - or is it not possible to set how large you want your onebox? I dont see any limit in the onebox/lib/onebox/engine/amazon_onebox.rb at main · discourse/onebox · GitHub so I thought it might be set more globally somewhere… Best regards,

Ahh, dooh. It seems like the source that the script rip data from by standart only contains 250 chars If you eg. go to https://www.amazon.com/gp/aw/d/0323353177/ And view it as user agent: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A405 Safari/7534.48.3 The div with productDescription only contains 250 chars. If you press the field you go to a new page with the path https://www.amazon.com/gp/aw/d/0323353177/#productDescription_secondary_view_div_1520843164890 Here you have the full description inside the div productDescription_fullView It should have a xpath //*[@id="productDescription_fullView"] A dirty solution in: onebox/lib/onebox/engine/amazon_onebox.rb at main · discourse/onebox · GitHub Find the empty line 85 add description = raw.at_css('#productDescription_fullView')&.inner_text Change line 104 description: raw.at("#productDescription")&.inner_text, to description: description, To have something like that [41]

It’s not possible to change the length of the onebox description unfortunately (the only adjustable is internal post onebox). Amazon onebox uses whatever is displayed as a description excerpt on mobile [27]

Okay, now you had made such a good date ripper for amazon - my hope was to be able to get even more data lenght then the onebox normally gives you. I can see: onebox/lib/onebox/engine/google_play_app_onebox.rb at main · discourse/onebox · GitHub use this code MAX_DESCRIPTION_CHARS: 500 But I dont know if I could use something like that in your script… :slight_smile:

It certainly can be done, we’d just have to decide on sensible description length which will be fixed then, so the onebox doesn’t get too big.

Not to maja specific - she did a great job adding the extension to the amazon script, but more generally. how do I enlarge the onebox for amazon to make a book review section at my site? Do I need to code a plugin or? I see this script: lib/onebox/engine/github_blob_onebox.rb main # frozen_string_literal: true require_relative '../mixins/git_blob_onebox' module Onebox module Engine class GithubBlobOnebox def self.git_regexp /^https?:\/\/(www\.)?github\.com.*\/blob\// end def self.onebox_name "githubblob" end include Onebox::Mixins::GitBlobOnebox def raw_regexp /github\.com\/(?

I was now able to set up a dev box via this topic: How to edit the discourse files? A development box? - #11 by mikechristopher Can anybody tell me where to find the file responseble for the amazon data ripper. It seems like is is not the file I thougt it was: https://github.com/discourse/onebox/blob/master/lib/onebox/engine/amazon_onebox.rb As there are no such file in my system. Even then the data output is like this on my dev box, with stars info and ISBN etc [image] Pathology for the Physical Therapist Assistant: 9780323395496: Medicine & Health...

onebox/lib/onebox/engine/amazon_onebox.rb at main · discourse/onebox · GitHub is correct file to modify. The best would be to clone the onebox library GitHub - discourse/onebox: (DEPRECATED) A gem for turning URLs into website previews · GitHub (run bundle install inside your onebox directory after cloning). After that you can change the code and run bundle exec rake server to preview changes in the browser on localhost:9000

This way? git clone https://github.com/discourse/onebox/blob/master/lib/onebox/engine/amazon_onebox.rb ~/discourse/lib/onebox Or should I create a new home folder a side discourse? git clone https://github.com/discourse/onebox/blob/master/lib/onebox/engine/amazon_onebox.rb ~/onebox

[image] frold: git clone https://github.com/discourse/onebox/blob/master/lib/onebox/engine/amazon_onebox.rb ~/onebox Use this one. If you want Discourse app to use your cloned onebox, you can replace gem 'onebox', '1.8.42' with gem 'onebox', path: 'path-to-your-cloned-onebox' (run bundle after changing Gemfile) Gemfile main gem "mail" gem "mini_mime" gem "mini_suffix" # NOTE: hiredis-client is recommended for high performance use of Redis # however a recent attempt at an upgrade lead to https://meta.discourse.org/t/rebuild-error/375387 # for now we are sticking with the socked based implementation that is not sensitive to this issue # gem "hiredis-client" gem "redis" # This is explicitly used by Sidekiq and is an optional dependency. # We tell Sidekiq to use the namespace "sidekiq" which triggers this # gem to be used. There is no explicit dependency in sidekiq cause # redis namespace support is optional # We already namespace stuff in DiscourseRedis, so we should consider # just using a single implementation in core vs having 2 namespace implementations gem "redis-namespace" # NOTE: AM serializer gets a lot slower with recent updates # we used an old branch which is the fastest one out there # are long term goal here is to fork this gem so we have a

Nice I was able to use gem 'onebox', path: '/Users/username/onebox/' Then I can edit a file and run bundle update before bundle exec rails server Or is there a easier way to do it?

You only have to run bundle once after changing Gemfile. After that you can run bundle exec rails server inside /discourse and it should work.
