Hi
I am trying to use widgets following the tutorials and screencasts provided. I first tried it in my app and in the section where I put <%= render_widget ... %> I keep getting the error message wrong number of arguments (1 for 0) so I followed the twitter tutorial exactly as its done on the website and the error message seems to be exactly the same. The error is as follows:
ArgumentError in Dashboard#index
Showing /Users/hosseinmirzapour/bar/app/views/dashboard/index.html.haml where line #5 raised:
wrong number of arguments(2 for 0)Extracted source (around line #5):

3: #dashboard
4: .column
5: = render_widget :twitter

Any help will be much appreciated
Many thanks

You probably have a Widget class on your app. This is overwriting Apotomo's own class methods.
At least that's what happened to me when I got this error.

I just tried it with a raw Rails 3.2.8 app and it works. Are you sure
you're working on a clean app? Also, please paste the TwitterWidget
here :-)

Yeah it definitely is a clean app following step by step what you did! TwitterWidget is as follows:
class TwitterWidget < Apotomo::Widget
responds_to_event :submit, :with => :process_tweet
def display
@tweets = Tweet.find(:all)
render
end
def process_tweet(evt)
Tweet.new(:text => evt[:text]).save
@tweets = Tweet.find(:all) # this is wet!
replace :view => :display
end
end
end
Many thanks :)

Sorry about that, for some reason I had both 1.1.4 and 1.2.3. I removed 1.1.4 and installed 1.2.3 which has solved the problem but now I am getting the following error:
really sorry about this and many thanks

Try requiring apotomo/rails/controller_methods.rb in the controller.
Also, in the controller do
class DashboardController < ..
include Apotomo::Rails::ControllerMethods
Does that help? Really strange, I tried it with a blank new app and
everything just works. Maybe you have some broken setup? Is it a new
app you're working on?

Does that help? Really strange, I tried it with a blank new app and
everything just works. Maybe you have some broken setup? Is it a new
app you're working on?
