RoR: SQLite3::ConstraintException: constraint failed =>rake db:seed

Question

When I run rake db:seed ,something are broken!

I get the following error:

ray@ray-virtual-machine:~/ticketee$ rake db:seed rake aborted! SQLite3::ConstraintException: constraint failed: INSERT INTO "users" ("admin", "confirmation_sent_at", "confirmation_token", "confirmed_at", "created_at", "current_sign_in_at", "current_sign_in_ip", "email", "encrypted_password", "last_sign_in_at", "last_sign_in_ip", "remember_created_at", "reset_password_sent_at", "reset_password_token", "sign_in_count", "updated_at") VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

Tasks: TOP => db:seed (See full trace by running task with --trace)

Here my seeds.rb:

admin_user = User.create(:email => "[email protected]", :password => "password") admin_user.admin = true

admin_user.confirm!

Project.create(:name => "Ticketee Beta")

Here my gem-list:

Tasks: TOP => db:seed

Can you tell me what happen in my code?I am a new.

Thanks a lot for your time.

Answer 1

My guess is that you are not providing all required fields when you call:

admin_user = User.create(:email => "[email protected]", :password => "password") 

What does your migration file for the table Users look like? What are the validations you have put into your Model Users?
