just getting to know the language by writing console twitter client, I'm
getting this error:
ArgumentError: wrong number of arguments (1 for 0)
from ./twitter_client.rb:7:in `initialize'
from ./twitter_client.rb:7:in `new'
from ./twitter_client.rb:7
from (irb):1:in `require'
from (irb):1
When trying to load the code below.
class TwitterMethod
Statuses = TwitterMethod.new("statuses/show")
def initialize(methodLocation) @methodUrlString = methodLocation
end
public
def call()
response
Net::HTTP.start(TwitterHome).start{|http|
request = Net::HTTP::Get.new(@methodUrlString) @credentials.sign(request)
response = http.request(request)
}
return JSON.parse(response)
end
end
I can't work out what is going wrong here, I am guessing that its
something to do with the class not being initialized by the time I call
TwitterMethod.new to set the class constant. I also don't know if this
is a particularly rubyish way to do this, please let me know if theres a
better way.
By default, the initializer of a class has no arguments. You are
calling TwitterMethod.new (which ends up calling initialize) with an
argument, instead of 0, before overriding the initialize method.
I don't know what you mean to do with the Statuses constant, so I'm
not sure if this is the best way to achieve it. But if you just want
to get rid of the error, put the initialize method before the call the
TwitterMethod.new.
Also, attr_accessor does the same as reader and writer.
Jesus.

Thanks guys, thats sorted it out. I didn't realize that the initialize()
override had to occur before instantiating a class. I guess I'm too used
to java
What I was trying to acheive with the 'Status' constant was something
similar to a java enum I suppose. The intention was to have a private
constructor with a class Constant for each twitter method.
