generate data from rails console

Question

Let's say I have User(name, password, email, zip code) table and I want to generate User objects with random data.

Is there a command( to use on rails console), which does that? something like User.generate.

Do you want generate fake data to seed your data base? – caspg Jul 06 '15 at 17:30 — caspg, Jul 06 '15 at 17:30

After adding the Faker gem to your gemfile, add this to your user.rb file.

def self.generate_new
  name     = Faker::Name.name 
  password = "foobar"
  email    = Faker::Internet.email
  zip      = Faker::Address.zip 
  User.create!(name:     name,
               passowrd: password,
               email:    email,
               zip:      zip)
end

After restarting your console, the command User.generate_new should run this command and generate a new user with random inputs.

Is there a way to know in advance what are compulsory fields that need to be filled in before creating an object(I don't want to check the presence validations each time I want to create an object) – Omar Lahlou Jul 06 '15 at 17:39
Do you want to skip the validations? Or are you just trying to find all the fields associated with the user and have it fill in data automatically? – nicholas79171 Jul 06 '15 at 17:43

@OmarLahlou I don't think that's possible. You can get column names [like this](http://stackoverflow.com/a/1291395/3251199) but getting variable types and such is not quite feasible, at least to my knowledge. You'll just have to add to this function whenever you add a new attribute. – nicholas79171 Jul 06 '15 at 17:48

Take a look at this gem: https://github.com/stympy/faker

It creates fake data for objects.
