Question

As soon as I add code to access my .sqlite database, I get a strange error:

in 'total': uninitialized constant Test2::SQLite (NameError)

My code is as follows:

Test1.rb

require_relative 'Test2.rb'

co = Test2.new()
price = co.total

Test2.rb

require 'sqlite3'

class Test2

    def initialize()
            @items = []
    end

    def total()
        db = SQLite::Database.open "Database.sqlite"
        db.close()
        return 0
    end
end

Answer 1

The SQLite module doesn’t exist, but it is named SQLite3 (check the docs):

require 'sqlite3'

class Test2

    def initialize()
            @items = []
    end

    def total()
        db = SQLite3::Database.open "Database.sqlite"
        db.close()
        return 0
    end
end
