Main Repository: http://github.com/commonthread/flickr_fu/tree/master
== Getting Started
You need to first get an API key as detailed here:
http://www.flickr.com/services/api/misc.api_keys.html
== Installation
sudo gem install flickr-fu
== Documentation
RDoc Documentation can be found here:
http://www.commonthread.com/projects/flickr_fu/rdoc/
== Example flickr.yml
--- !map:HashWithIndifferentAccess
key: "YOUR KEY"
secret: "YOUR SECRET"
token_cache: "token_cache.yml"
== Authorization
To authorise your application to access Flickr using your API key you will
need to access a specific URL.
To generate this URL run the following and when presented with the URL
access it from your browser. Confirm the application has permission at
the level you have specified.
Note that flickr has different types of keys. If you use one for a webapplication,
which is most likely, you need to define a callback and somehow make sure that
you connect the parameter :frob that flickr send via the callback is assigned
to the right user account. The best way to do this is to loop over all the current
user's flickr accounts and try flickr.auth.token with the :frob.
Finally, cache the token (this will create the token cache file)
If you have an invalid API key you will see errors such as:
"100: Invalid API Key"
If you don't follow the process below to authorise your application
you will see errors such as:
"98: Login failed / Invalid auth token" or
"99: User not logged in / Insufficient permissions"
== Authorization Example for non-webapplication
require 'flickr_fu'
flickr = Flickr.new('flickr.yml')
puts "visit the following url, then click <enter> once you have authorized:"
# request write permissions
puts flickr.auth.url(:write)
gets
flickr.auth.cache_token
== Authorization Example for a webapplication
flickr.auth.token also contains the nsid and username, this
example only stores the token and no other userdata.
require 'flickr_fu'
class FlickrController < ActionController::Base
def create
flickr = Flickr.new('flickr.yml')
redirect_to flickr.auth.url(:write)
end
def flickr_callback
flickr = Flickr.new('flickr.yml')
flickr.auth.frob = params[:frob]
current_user.update_attribute :flickr_token, flickr.auth.token.token
end
def something_else_with_flickr
flickr = Flickr.new(YAML.load_file('flickr.yml').merge(:token => current_user.flickr_token))
# now you have full access on the user's data :)
end
end
== Search Example
require 'flickr_fu'
flickr = Flickr.new('flickr.yml')
photos = flickr.photos.search(:tags => 'ruby-flickr')
puts "found #{photos.size} photo(s)"
photos.each do |photo|
puts photo.title
puts photo.description unless [nil, ''].include?(photo.description)
[:square, :thumbnail, :small, :medium, :large, :original].each do |size|
puts "#{size}: #{photo.url(size)}"
end
puts "comments: #{photo.comments.size}"
photo.comments.each do |comment|
intro = "#{comment.author_name} says - "
puts "#{intro}\"#{comment.comment.gsub("\n", "\n"+(" "*intro.length))}\""
end
puts "notes: #{photo.notes.size}"
photo.notes.each do |note|
puts "[#{note.x},#{note.y} ~ #{note.width}x#{note.height}] - \"#{note.note}\""
end
puts
puts
end
== Another Search Example
If searching for photos by user id then you need to specify the 'alias' - without
intervention this is usually set by Flickr and is an alphanumeric string.
To find out the user id for a given user, you can use the tool at:
http://idgettr.com/
And replace the line in the above sample to query on user id:
photos = flickr.photos.search(:user_id => 'your_user_id_here')
