verifyまわりのコードを読む

verification.rb を読んでみる。

def verify(options={})

filter_opts = { :only => options[:only], :except => options[:except] }

before_filter(filter_opts) do |c|

c.send :verify_action, options

end

end

filters.rbのコメントにこんな記述が。

# The filter method is passed the controller instance and is hence granted access to all aspects of the controller and can

# manipulate them as it sees fit.

#

# The inline method (using a proc) can be used to quickly do something small that doesn't require a lot of explanation.

# Or just as a quick test. It works like this:

#

#   class WeblogController < ActionController::Base

#     before_filter { |controller| false if controller.params["stop_action"] }

#   end

あー、なるほど。verify_actionを書き換えてみる。

def verify_action(options) #:nodoc:

prereqs_invalid =

[*options[:params] ].find { |v| params[v].nil?  } ||

[*options[:session]].find { |v| session[v].nil? } ||

[*options[:flash]  ].find { |v| flash[v].nil?    }



if !prereqs_invalid && options[:method]

prereqs_invalid ||=

[*options[:method]].all? { |v| request.method != v.to_sym }

end



prereqs_invalid ||= (request.xhr? != options[:xhr]) unless options[:xhr].nil?



if prereqs_invalid

flash.update(options[:add_flash]) if options[:add_flash]

response.headers.update(options[:add_headers]) if options[:add_headers]

unless performed?

render(options[:render]) if options[:render]

options[:redirect_to] = self.send(options[:redirect_to]) if options[:redirect_to].is_a? Symbol

redirect_to(options[:redirect_to]) if options[:redirect_to]

end

#        return false

return true # ここ

end



true

end

これでverify処理が無効になる。verifyまわりの処理を理解した。
