未显示RoR Faker信息

Question

我安装了'faker‘gem，但当我使用它(Faker::Book.name)时，它不会显示一个随机名称，而只显示一个字符串"Faker::Book“

lib > tasks > data_populate

require 'colorize'

namespace :data_populate do

namespace :populate do
    desc "Populate all model data set"
    task :all => :environment do
        require 'faker'
        puts "\n'Populating Model Data'".yellow
        Job.where(name: "Faker::Book").destroy_all
        10.times do |l|
            Job.create(name: Faker::Book.name, description: Faker::Lorem.sentence(7), business_id: 1)
        end
    end #all end
end #populate end
end #end rake dashboard

当代码运行时，Job Title始终是"Faker::Book“

Answer 1

"Faker::Book"不能存储到db中，它的name方法只能选择一个随机的Name值，所以它不能在where子句中通过类名来匹配，所以你只需要尝试定义一些constance name部分，并对其进行匹配：

Job.where("name LIKE 'faker%'").destroy_all
10.times do |l|
   Job.create(name: "faker " + Faker::Book.name, description: Faker::Lorem.sentence(7), business_id: 1)
end
