问题
Apologies in advance for ultra-long post, just trying to include all the info...
I have an app using Devise in which I use a rakefile to seed the database with users among other things. This worked recently, but I can't for the life of me tell what happened over the last few set of changes and it probably just needs a fresh pair of eyes.
Here's the bang-head-against-wall twist:
- running the rakefile on localhost works correctly
- running the rakefile after pushing to Heroku gives the errors I'll detail below
- running the same Create commands from "heroku run rails console -a " also works correctly
Here's the user schema:
create_table "users", force: true do |t|
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.datetime "created_at"
t.datetime "updated_at"
t.string "job_title"
t.string "first_name"
t.string "last_name"
t.string "confirmation_token"
t.datetime "confirmed_at"
t.datetime "confirmation_sent_at"
t.string "unconfirmed_email"
t.integer "role"
t.integer "company_id"
t.string "company_type"
t.string "avatar_file_name"
t.string "avatar_content_type"
t.integer "avatar_file_size"
t.datetime "avatar_updated_at"
end
And the relevant parts of the model...
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Before actions
before_save { self.email = email.downcase }
# Validation constants
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
# Validation filters
validates :email, presence: true, format: {with: VALID_EMAIL_REGEX}, uniqueness: {case_sensitive: false}
validates :role, presence: true
validates :company, presence: true
# Relationships
belongs_to :company, polymorphic: true
end
And controller stuff:
class UsersController < ApplicationController
# Authenticate user
before_filter :authenticate_user!
def create
User.create(user_params)
end
private
def user_params
params.require(:user).permit(:first_name, :last_name, :email, :encrypted_password, :job_title, :role, :company)
end
and more...
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
# Modules to include
include SessionsHelper
# Before filters
before_action :configure_permitted_parameters, if: :devise_controller?
# Ensure authorization is setup in every action in the application
# check_authorization
# Devise after sign in redirect to profile page
def after_sign_in_path_for(resource)
"/home?login=true"
end
protected
def configure_permitted_parameters
devise_parameter_sanitizer.for(:sign_up) << :first_name
devise_parameter_sanitizer.for(:sign_up) << :last_name
devise_parameter_sanitizer.for(:sign_up) << :job_title
devise_parameter_sanitizer.for(:sign_up) << :role
devise_parameter_sanitizer.for(:sign_up) << :company_id
devise_parameter_sanitizer.for(:sign_up) << :company_type
devise_parameter_sanitizer.for(:account_update) { |u| u.permit(:first_name, :last_name, :job_title, :current_password) }
end
end
And finally, from my rake file:
Vendor.all.each { |vendor|
domain = EmailDomain.where(company: vendor).first.domain
5.times do |n|
first_name = Faker::Name.first_name
last_name = Faker::Name.last_name
email = "example-#{n+1}@#{domain}"
password = "password"
User.create!(first_name: first_name,
last_name: last_name,
email: email,
password: password,
password_confirmation: password,
role: User::VENDOR_USER,
company: vendor,
job_title: "Sales Manager")
end
}
The error:
rake aborted!

(See full trace by running task with --trace)
It's not specific to just role, will give the error to job_title if I rearrange the order of the parameters in the create.
One last note, among the recent changes was the overdue upgrade of many gems, including Devise from 3.2.2 to 3.3.0...seems like the project was getting away with something it no longer can. Strong parameter updates were made of late in attempt to get this to work.
