html - Rails tab selection -

-

i have tab-like button interface interact site using following html

<li class="current_page_item"><a href="/home" class="first">home</a></li> <li><a href="/projects">projects</a></li> <li><a href="/resume">resume</a></li> <li><a href="/contact">contact</a></li>

the class="current_page_item attribute changes of tab. each url view managed my staticpages controller, how can make each view have respective 'tab' selected?

current_page?(url) method can you.

create additional helper method.

module applicationhelper   #...   def tab_item(name, url)     opts = {}     opts[:class] = 'current_page_item' if current_page?(url)     content_tag :li, opts       link_to name, url     end   end   #... end

and use in view

<%= tab_item 'home', root_path %> <%= tab_item 'projects', projects_path %> <%= tab_item 'resume', resume_path %> <%= tab_item 'contact', contact_path %>

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.
