None of the data in seeds.rb is loaded into the development db. There is no error message. How can I determine the cause?
If I run rake:db:migrate:reset it just runs and produces no error messages. The if I go to the console, run User.first, it says nil. Also I downloaded the development db and there are no records in it (tables are created correctly, just no records).
Is there some way to trace the cause?
Part of seeds.rb:
User.create!(fullname: "Example User",
username: "fakename0",
email: "example#railstutorial.org",
admin: true,
activated: true,
activated_at: Time.zone.now,
password: "foobar",
password_confirmation: "foobar")
User.create!(fullname: "Example User 2",
username: "fawwkename0",
email: "exaaample#railstutorial.org",
admin: false,
activated: true,
activated_at: Time.zone.now,
password: "foobar",
password_confirmation: "foobar")
99.times do |n|
fullname = Faker::Name.name
username = "fakename#{n+1}"
email = "example-#{n+1}#railstutorial.org"
password = "password"
User.create!(fullname: fullname,
username: username,
email: email,
password: password,
password_confirmation: password,
activated: true,
activated_at: Time.zone.now)
end
Message.create!(email: "example#example.com",
name: "Example User",
content: "This is my message")
Organization.create!(org_name: "Fictious business",
bio: "The background of the organization here",
actioncode: 111)
99.times do |n|
org_name = Faker::Company.name
bio = Faker::Lorem.paragraph(2)
actioncode = Faker::Number.number(3)
Organization.create!(org_name: org_name,
bio: bio,
actioncode: actioncode)
end
Member.create!(organization_id: rand(1..100),
email: "me#example.com",
username: "fake-name0",
fullname: Faker::Name.name,
activated: 1,
activated_at: Time.zone.now,
password: "foobar",
password_confirmation: "foobar")
99.times do |n|
organization_id = rand(1..100)
email = "rails0-#{n+1}#example.com"
username = "fake-name#{n+1}"
fullname = Faker::Name.name
activated = rand(0..1)
activated_at = Faker::Date.backward(14) if activated==1
password = "foobar"
password_confirmation = "foobar"
Member.create!(organization_id: organization_id,
email: email,
username: username,
fullname: fullname,
activated: activated,
activated_at: activated_at,
password: password,
password_confirmation: password_confirmation)
end
To load db/seeds.rb you need to run rake db:seed.

I want to create dozens of logins that rely on data from this array, logins:
logins = [
{
email: Faker::Internet.email,
password: "password",
first_name: Faker::Name.first_name,
last_name: Faker::Name.last_name
},
{
email: Faker::Internet.email,
password: "password",
first_name: Faker::Name.first_name,
last_name: Faker::Name.last_name
}
]
What is a better way of writing this array rather than copy and pasting that hash dozens of times? I am familiar with x.times do but that wouldn't work on an array.
Here's the code where I pass in the logins:
logins.each do |login|
li = LoginInformation.new(login: login[:email], password: login[:password])
if UserManager.save(li)
company_ids.each do |id|
li.contacts.create(first_name: login[:first_name], last_name: login[:last_name], email_address: login[:email], company_id: id, is_employee: true)
end
end
end
One way to simplify the creation of your logins array is to pass the hash object with the included Faker methods as a block, like so:
logins = Array.new(10) { { email: Faker::Internet.email, password: 'password', first_name: Faker::Name.first_name, last_name: Faker::Name.last_name } }
You can replace the 10 in this example with the number of elements required for your use case.
Hope this helps!
.times returns an enumerator that you can call .map on to get an array.
logins = 10.times.map do
{
email: Faker::Internet.email,
password: "password",
first_name: Faker::Name.first_name,
last_name: Faker::Name.last_name
}
end
Or use Array.new as mentioned by Zoran Pesic.
You can use for loop to insert the values multiple times
logins=[]
for i in 0..10
logins <<
{
email: Faker::Internet.email,
password: "password",
first_name: Faker::Name.first_name,
last_name: Faker::Name.last_name
}
end
Can do this way also:
10.times do
login = { email: Faker::Internet.email, password: 'password', first_name: Faker::Name.first_name, last_name: Faker::Name.last_name }
li = LoginInformation.new(login: login[:email], password: login[:password])
if UserManager.save(li)
company_ids.each do |id|
li.contacts.create(first_name: login[:first_name], last_name: login[:last_name], email_address: login[:email], company_id: id, is_employee: true)
end
end
end
I try to seed data for my app. I managed to do this, but the code is ugly, and it possibly can be a lot easier. I;m a complete beginner so I would be grateful for any help. I had to create one profile and one todolist for each user, and 5 todoitems for each todolist.
user1 = User.create!( username: "Fiorina", password_digest: "123456")
profile1 = user1.create_profile(gender: "female", first_name: "Carly", last_name: "Fiorina", birth_year: 1954)
todolist1 = user1.todo_lists.create(list_name:"List1", list_due_date:Date.today + 1.year)
user2 = User.create!( username: "Trump", password_digest: "123456")
profile2 = user2.create_profile( gender: "male", first_name: "Donald", last_name: "Trump", birth_year: 1946)
todolist2 = user2.todo_lists.create(list_name:"List2", list_due_date:Date.today + 1.year)
user3 = User.create!( username: "Carson", password_digest: "123456")
profile3 = user3.create_profile( gender: "male", first_name: "Ben", last_name: "Carson", birth_year: 1951)
todolist3 = user3.todo_lists.create(list_name:"List3", list_due_date:Date.today + 1.year)
user4 = User.create!( username: "Clinton", password_digest: "123456")
profile4 = user4.create_profile( gender: "female", first_name: "Hillary", last_name: "Clinton", birth_year: 1947)
todolist4 = user4.todo_lists.create(list_name:"List4", list_due_date:Date.today + 1.year)
for i in 0..4
todolist1.todo_items.create(due_date: Date.today + 1.year, title: "TodoItem1", description: "Opis", completed: 1)
end
for i in 0..4
todolist2.todo_items.create(due_date: Date.today + 1.year, title: "TodoItem2", description: "Opis", completed: 1)
end
for i in 0..4
todolist3.todo_items.create(due_date: Date.today + 1.year, title: "TodoItem3", description: "Opis", completed: 1)
end
for i in 0..4
todolist4.todo_items.create(due_date: Date.today + 1.year, title: "TodoItem4", description: "Opis", completed: 1)
end
DRY it (don't repeat yourself):
[
{last_name:'Fiorina', first_name:'Carly', gender:'female', birth_year:1954},
{last_name:'Trump', first_name:'Donald', gender:'male', birth_year:1946},
{last_name:'Carson', first_name:'Ben', gender:'male', birth_year:1951},
{last_name:'Clinton', first_name:'Hillary', gender:'female', birth_year:1947},
].each_with_index do |p, index|
user = User.create!( username: p[:last_name], password_digest: "123456")
profile = user.create_profile(p) # note that p only has fields for profile attributes
todolist = user.create_todo_list(list_name:"List#{index+1}", list_due_date:Date.today + 1.year)
5.times.each{|i|
todolist.create_todo_item(due_date: Date.today + 1.year, title: "TodoItem#{i+1}", description: "Opis", completed: 1)
}
end
Hey you can build_profile for has_one relation ship and used todo_lists.build for has_many try this way
User.create!( username: "Fiorina", password_digest: "123456").build_profile(gender: "female", first_name: "Carly", last_name: "Fiorina", birth_year: 1954).save!
for has_many relation ship
User.create!( username: "Fiorina", password_digest: "123456").todo_lists.build().save!
I'm trying to setup my seed like this:
company = Company.create!( name: 'Hirthe-Ritchie',
time_zone: 'Stockholm',
users_attributes: [{
first_name: 'Demo',
last_name: 'Memo',
title: 'CEO',
email: 'demo#demo.com',
time_zone: 'Stockholm',
admin: true,
password: 'foobar',
activated: true,
activated_at: Time.zone.now,
reviewer_attributes: {
reviewer_user_id: # parent id
}
}]
)
now what I want is that on reviewer_attributes, to make reviewer_used_id, the user id of the user being created.
So I have user_id and reviewer_user_id in my Reviewer model, now how do I get the parent's id in a nested attribute like I have here?
You will have to split your code into several new/create between the related objects. Try the following:
user_attrs = {
first_name: 'Demo',
last_name: 'Memo',
title: 'CEO',
email: 'demo#demo.com',
time_zone: 'Stockholm',
admin: true,
password: 'foobar',
activated: true,
activated_at: Time.zone.now
}
user = User.new(user_attrs)
user.reviewer = user
company = Company.new(name: 'Hirthe-Ritchie', time_zone: 'Stockholm')
company.users << user
company.save!
I can't figure out why this code is not populating my sqlite database. I am using the faker gem with rails 3.2 and am trying to make a twitter like application. Can anyone find the problem?
namespace :db do
desc "Fill database with sample data"
task populate: :environment do
def make_users
User.create!(name: "Example User",
email: "example#example",
password: "foobar",
password_confirmation: "foobar")
99.times do |n|
name = Faker::Name.name
email = "example-#{n+1}#example.org"
password = "password"
User.create!(name: name,
email: email,
password: password,
password_confirmation: password)
end
end
def make_microposts
users = User.all(limit: 6)
50.times do
content = Faker::Lorem.sentence(5)
users.each { |user| user.microposts.create!(content: content) }
end
end
def make_relationships
users = User.all
user = users.first
followed_users = users[2..50]
followers = users[3..40]
followed_users.each { |followed| user.follow!(followed) }
followers.each { |follower| follower.follow!(user) }
end
end
end
I figured out the answer actually. Here is the correct code:
namespace :db do
desc "Fill database with sample data"
task populate: :environment do
make_users
make_microposts
make_relationships
end
end
def make_users
User.create!(name: "Example User",
email: "example#railstutorial.org",
password: "foobar",
password_confirmation: "foobar")
99.times do |n|
name = Faker::Name.name
email = "example-#{n+1}#railstutorial.org"
password = "password"
User.create!(name: name,
email: email,
password: password,
password_confirmation: password)
end
end
def make_microposts
users = User.all(limit: 6)
50.times do
content = Faker::Lorem.sentence(5)
users.each { |user| user.microposts.create!(content: content) }
end
end
def make_relationships
users = User.all
user = users.first
followed_users = users[2..50]
followers = users[3..40]
followed_users.each { |followed| user.follow!(followed) }
followers.each { |follower| follower.follow!(user) }
end
I want to populate the database with a number of stores and users, that each user corresponds to one store. The issue with the code below is that I get the error Validation failed: Email has already been taken.
namespace :db do
desc "Fill database with sample data"
task populate: :environment do
make_stores
make_users
end
end
def make_stores
50.times do
name = Faker::Company.name
manager = Faker::Name.name
address = Faker::Address.street_name
Store.create!(name: name,
manager: manager,
address: address)
end
end
def make_users
stores = Store.all(limit: 8)
99.times do |n|
first_name = Faker::Name.first_name
last_name = Faker::Name.last_name
email = "example-#{n+1}#example.org"
password = "password"
stores.each { |store| store.users.create!(first_name: first_name,
last_name: last_name,
email: email,
password: password,
password_confirmation: password) }
end
end
The problem is that you're setting the email variable before calling stores.each, so all 8 stores will get a user with the same email.
Do something like this instead:
def make_users
stores = Store.all(limit: 8)
99.times do |n|
password = "password"
stores.each do |store|
first_name = Faker::Name.first_name
last_name = Faker::Name.last_name
email = "#{store.name.parameterize}-#{n+1}#example.org"
store.users.create!(first_name: first_name,
last_name: last_name,
email: email,
password: password,
password_confirmation: password)
end
end
end
Now the first 8 users will have an email like (some-store-name)-1#example.org, next 8 will have (some-store-name)-2#example.org and so on.
