Disqus Ruby Gem

The Disqus Gem helps you easily integrate the Disqus commenting system into your website. It works for any site programmed in Ruby, and has view helpers for Rails and Merb.

Support for the Disqus Javascript widgets is stable. Disqus API support is “beta.”

What is Disqus?

From the Disqus website:

“Disqus, pronounced ”discuss“, is a service and tool for web comments and discussions. The Disqus comment system can be plugged into any website, blog, or application. Disqus makes commenting easier and more interactive, while connecting websites and commenters across a thriving discussion community.”

“Disqus is a free service to the general public with absolutely no inline advertisements.”

Get it

gem install disqus

Bleeding Edge

gem install norman-disqus  --source http://gems.github.com

Use it:

Configure it:

Generic example:
Disqus::defaults[:account] = "my_disqus_account"
# Optional, only if you're using the API
Disqus::defaults[:api_key] = "my_disqus_api_key"
Rails example:
# in config/development.rb (or production.rb, test.rb, etc.)
config.after_initialize do
  Disqus::defaults[:account] = "my_disqus_account"
  # Optional, only if you're using the API
  Disqus::defaults[:api_key] = "my_disqus_api_key"
end

Note that here the “after initialize” is necessary, otherwise your settings won't be set properly.

Merb example:
# in config/init.rb
Merb::BootLoader.after_app_loads do
  Disqus::defaults[:account] = "my_disqus_account"
  # Optional, only if you're using the API
  Disqus::defaults[:api_key] = "my_disqus_api_key"
end

Note that here the “after_app_loads” is necessary, otherwise your settings won't be set properly.

Options
:api_key => "" # your api key
:account => "", # your disqus account
:developer => false, # allows for threads to work on localhost
:container_id => 'disqus_thread', # desired thread container
:avatar_size => 48, # squared pixel size of avatars
:color => "grey", # theme color
:default_tab => "popular", # default widget tab
:hide_avatars => false, # hide or show avatars
:hide_mods => true, # hide or show moderation
:num_items => 15, # number of comments to display
:show_powered_by => true, # show or hide powered by line
:orientation => "horizontal" # comment orientation

Show the comment threads widget on a post page:

# Loads the commenting system
disqus_thread

# Or if you're not using Rails/Merb:
Disqus::Widget::thread

# Sets the inner html to the comment count for any links on the page that
# have the anchor "disqus_thread". For example, "View Comments" below would
# be replaced by "1 comment" or "23 comments" etc.
# <a href="http://my.website/article-permalink#disqus_thread">View Comments</a>
# <a href="http://my.website/different-permalink#disqus_thread">View Comments</a>
disqus_comment_counts

# Or if you're not using Rails/Merb:
Disqus::Widget::comment_counts

Show the combo widget on a post page:

disqus_combo(:color => "blue", :hide_mods => false, :num_items => 20)

# Or for non-Rails/Merb:
Disqus::Widget::combo(:color => "blue", :hide_mods => false, :num_items => 20)

Show the comment count on a permalink:

link_to("Permalink", post_path(@post, :anchor => "disqus_thread"))
...
disqus_comment_counts

# Or for non-Rails/Merb:
Disqus::Widget::comment_counts
