I am new to rails and new to this mailling list, if some thing I said wrong, please forgive me and correct me I am try to make our project support emotion (emoji), after a few search, I find html-pipeline (https://github.com/jch/html-pipeline) I can install it and use it in console(rails c and without require ''html/pipeline'') but when I try to use it in my project, always fail with uninitialized constant HTML::Pipeline( I try to use it in model, application_helper ) and require ''html/pipeline'' fail too here is my question 1. where should I place this kind of code (format some content, markdown, emotion, highline syntax etc) 2. I see a cast about `Redcarpet`, it just place it in Gemfile and bundle install and then can use directly, why can ''html/pipeline'' (HTML::Pipeline) thanks in advance -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

After you do that bundle and then it *should* work if it doesn''t there needs to be an actual error (trace) sent. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

thanks for you answer, it already out of any group, and I place it at the
bottom still get error, maybe problem is not in installation (rails c can
work) I place this code in my comment model (app/models/comment.rb)
def markdown
#require "html/pipeline"
filter = HTML::Pipeline::MarkdownFilter.new("Hi **world**!")
return filter.call
end
I got NameError - uninitialized constant HTML::Pipeline:
if I uncomment require line I got LoadError - cannot load such file --
html/pipeline:
I know I must make some stupid mistake, but just don''t know it

Watch your console as the application starts, and see what you see then. The error acts like the gem never loaded, so maybe requiring it that late (just before you need it) is the issue.
