ruby on rails - Scoping require class loading, etc -

-

i have file booking.rb in model directory. contains class definition 

class booking < activerecord::base   def self.setup_connection       wsdlurl = 'http://10.14.47.201:7001xxx/webservice/retrievebookingsbycclv1_01.wsdl'       factory = soap::wsdldriverfactory.new(wsdlurl)       @@driver = factory.create_rpc_driver       @@driver.return_response_as_xml = true     end end

i attempt invoke method application.rb see code below.

module pnr2   class application < rails::application       ...       ...       booking.setup_connection     end   end

this fails following when run app...

  c:/users/sg0209028/rubymineprojects/pnr2/config/application.rb:49:in   `<class:application>': uninitialized constant pnr2::application::booking (nameerror)    c:/users/sg0209028/rubymineprojects/pnr2/config/application.rb:18:in `<module:pnr2>'    c:/users/sg0209028/rubymineprojects/pnr2/config/application.rb:17:in `<top (required)>

the reason reference line 49 removed comments in application.rb file avoid taking space in note. line 49 in original booking.setup_connection line.

i not understanding how name scoping working in rails 3. maybe don't understand when should invoking class method set constant in model object. feels should application initialization task, maybe request should somewhere else.

ib case wondering, have had code , invocation of appropriate web services working in straingth ruby (non rails) environment.

below code that

require 'soap/wsdldriver' require 'rexml/document' require 'soap/rpc/driver' wsdl_url = "http://10.14.47.202:7001/xxx/webservice/retrievebookingsbycclv1_01.wsdl" factory = soap::wsdldriverfactory.new(wsdl_url) driver = factory.create_rpc_driver driver.return_response_as_xml = true params = {"ccl" => "booking[bookingname[bookingnameitem[ticketnumber > \"123456789\"]]]", "xmlformat" => "defaultbooking"} response = driver.retrievebookingsbyccl(params) doc = rexml::document.new response puts "number of pnrs = " + rexml::xpath.first(doc, "//count").text doc.elements.each ("//origincity") {|element| puts "element = " + element.text}

can please give newbie pointers? oh , yes realize invoking soap based services instead of ending database going have issues. prepared once connection work!

thanks in advance

i realized trying use booking class in application.rb file. think going have issues because @ point application not configured, if can around those, use model, you'll have require file @ top of application.rb file:

require 'rails/all' require file.join(file.dirname(__file__), '../app/models/booking')

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
