ruby - How to return an object from two tables form a rails web serivce? -

-

i have 2 activerecord models: event , place. event has property name place_id points place. place has column named place_name.

how write web service returns json of events each event holds associated place_name value.

i tried adding attr_accessor field name place_name event model , populate manually after selecting events. when do: render :json => events_collection_result

the place_name doesn't appear in json.

all of logic falls under activerecord associations. it's fundamental piece of rails functionality, it's documented. guide should more suffice.

you'll want invoke belongs_to :place if event class definition. there, can access event's place name via @event.place.place_name, although i'd recommend rename place_name name.

json won't display association default. there plenty of ways remedy this, basic of overwrite event#to_json, method called default when rails attempts produce json representation of activerecord instance.

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.
