[Rails] CalendarHelper

Has anyone had any luck using the CalendarHelper plugin at 
http://wiki.rubyonrails.com/rails/pages/CalendarHelper recently?

I''m scratching my head over the following error when I look at any page
in my application:

 NameError in CalendarController#index

undefined local variable or method `date_format'' for 
#<CalendarController:0x24ccd4c>

I''m sure this is a bad user on device error, but I would appreciate any

Did you look at an intact version of the wiki page? It was botched and I 
have just rolled it back to a previous. correct state. 

That said, as the original author of this beast, I have to admit that it 
is a bit unwieldy and certainly warrants to be encapsulated in a 
plugin.

helped.  My problem appears to be with date_format getting added to 
ActiveRecord:Base.  I get the following error message:

 NameError in CalendarController#index

undefined local variable or method `date_format'' for 
#<CalendarController:0x24cc98c>


I''m sure this is something stupid, but I''m new to Rails, and
therefor
dumb.

It will be a nice little project for me.

Thanks,

Ah, yes, I see. The cause is indeed very simple: date_format is not 
defined anywhere. The reason is, that it is really up to your app and 
the localization package (if any) you''re using. If you don''t
have to
deal with that stuff, just do it like this

class ApplicationController < ActionController::Base
  prepend_before_filter :localize

  def localize
    # determine locale and set other relevant stuff
    # ...
    ActiveRecord::Base.date_format = ''%Y-%m-%d'' # or
''%m/%d/Y'' or ...
  end
end

That was dumb, even for me!  Thanks for the help.

[Rails] Re: CalendarHelper

Okay, next silly question.  I''m trying to create a very simple 
index.rhtml to display a flat calendar.  So far I''ve got:

<%= stylesheet_link_tag ''calendar-system.css'' %>
<%= javascript_include_tag ''calendar'',
''calendar-en'', ''calendar-setup''
%>

<html>
<h2>Calendar!</h2>
<%= calendar ''person'', ''birthday'',
        { :class => ''date'' },
        { :firstDay => 1,
          :range => [1920, 1990],
          :step => 1,
          :showOthers => true }
%>
</html>

When I hit this page I get the following message:

 NoMethodError in Calendar#index

Showing app/views/calendar/index.rhtml where line #6 raised:

undefined method `calendar'' for
#<#<Class:0x22ddab8>:0x22dda90>

Does this mean that my page isn''t finding the the calendar method from 
calendar_helper.rb, or am I failing to declare something in my 
controller?

Sorry about the newbie questions.  Hopefully I will leave this phase 
soon.

Thanks,
Steve

Yes. Either in your application controller 
(app/controllers/application.rb) or in the individual controllers whose 
views use the calendar helper you need to include and declare the new 
helper methods

class MyController < ApplicationController
  ...
  include BoilerPlate::Helpers::ActionHelper
  helper BoilerPlate::Helpers::ActionHelper
  ...
end

HTH,
Michael

[Rails] Re: CalendarHelper

I seem to be making some progress.  I''ve modified my controller to:

class CalendarController < ApplicationController

  include BoilerPlate::Helpers::ActionHelper
  helper BoilerPlate::Helpers::ActionHelper

  layout ''default''


  def index
  end

end

When I hit the page, it throws an exception.  I get the following 
message in development.log:

uninitialized constant Helpers
./script/../config/../vendor/rails/activesupport/lib/active_support/dependencies.rb:123:in
`const_missing''
script/../config/../app/controllers/calendar_controller.rb:3

I assume this means that Helpers isn''t being correctly defined?

Thanks,
Steve

Most likely you need to require the file containing 
BoilerPlate::Helpers::ActionHelper.
