ActionController::UnknownHttpMethod exception found under rails 3.0.1
$ cat lib/http_method_not_allowed.rb
# Render 405 response for ActionController::UnknownHttpMethod exceptions like:
# (ActionController::UnknownHttpMethod) "CONNECT, accepted HTTP methods are get, head, put, post, delete, and options"
# (ActionController::UnknownHttpMethod) "PROPFIND, accepted HTTP methods are get, head, put, post, delete, and options"
class HttpMethodNotAllowed
def initialize(app)
@app = app
end
def call(env)
# irb(main):001:0> ActionController::Request::HTTP_METHODS # => ["get", "head", "put", "post", "delete", "options"]
if !ActionController::Request::HTTP_METHODS.include?(env["REQUEST_METHOD"].downcase)
Rails.logger.info("ActionController::UnknownHttpMethod: #{env.inspect}")
[405, {"Content-Type" => "text/plain"}, ["Method Not Allowed"]]
else
@status, @headers, @response = @app.call(env)
[@status, @headers, @response]
end
end
end
Use HttpMethodNotAllowed as middleware config/application.rb
config.middleware.use "HttpMethodNotAllowed"

fixed by adding the following on in application.rb
require File.expand_path('../../lib/http_method_not_allowed', __FILE__)

This works to suppress the error.

@dleve123 to suppress rack exceptions in general, set RACK_ENV to deployment.
