ruby - In-Memory Sqlite DB in Rails with Rspec -

-

i have rails 4 application i'm attempting test in rspec using in-memory sqlite database. when run rake tells me

have 66 pending migrations. run `rake db:migrate` update database try again.

spec_helper.rb

env["rails_env"] ||= 'test'  require file.expand_path("../../config/environment", __file__) require 'rspec/rails' require 'capybara/rails' require 'capybara/rspec' require 'rspec/autorun' require 'capybara/poltergeist' require 'faker' require 'rake'  load_schema = lambda {   load "#{rails.root.to_s}/db/schema.rb" }  load_schema[]  ...

why getting error? why need run migrations when i'm loading schema file? correct way test using sqlite in-memory db?

update

when running rake -t appears rake attempting run migrations

** invoke default (first_time) ** invoke spec (first_time) ** invoke test:prepare (first_time) ** invoke db:test:prepare (first_time) ** invoke db:load_config (first_time) ** execute db:load_config ** execute db:test:prepare ** invoke db:test:load (first_time) ** invoke db:test:purge (first_time) ** invoke environment (first_time) ** execute environment ** invoke db:load_config ** execute db:test:purge ** execute db:test:load ** invoke db:test:load_schema (first_time) ** invoke db:test:purge ** execute db:test:load_schema ** invoke db:schema:load (first_time) ** invoke environment ** invoke db:load_config ** execute db:schema:load ** invoke db:test:load ** invoke db:abort_if_pending_migrations (first_time) ** invoke environment ** execute db:abort_if_pending_migrations

i don't need run migrations. possible override seemingly default behavior.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
