Good evening. I have a problem. i am using has_secure_password
and cause of this i have an error undefined methodpassword_digest=' for #`,
but i dont have this method!! Please help, dont know what to do. I read how to fix this problem but it didnt help me(
Here is my User model. Please help if you can.
class User < ActiveRecord::Base
attr_accessible :email, :password, :password_confirmation
has_secure_password
validates_presence_of :password, :on => :create
before_create { generate_token(:auth_token) }
def send_password_reset
generate_token(:password_reset_token)
self.password_reset_sent_at = Time.zone.now
save!
UserMailer.password_reset(self).deliver
end
def generate_token(column)
begin
self[column] = SecureRandom.urlsafe_base64
end while User.exists?(column => self[column])
end
end
You may have forgotten to make sure your migration backing the user model has a column for password_digest. Make sure the column exists and that it's a string. If it doesn't, create a migration to add the column.
Models having has_secure_password store password in password_digest column instead of password column.
In fact password column is not needed.
> u=User.create!(email: 'user#gmail.com', password: '12345678')
> u
#<User:0x007fc794be9278> {
:id => 1,
:email => "user#gmail.com",
:password_digest => "$2a$10$S82GVFR..yO9jihgIoeMj.7dNMWtbCUZpWDKvH0tyMs1SYlfdefmW"
}
I had the same problem, I was following http://www.railstutorial.org/book/modeling_users
and my app/Controllers/users_controllers.rb didn't have a method to create the attribute, I also used git to share the working code between portable laptop for the train and larger home, this created the migration file but didnt apply it, my working user controller is below.
class UsersController < ApplicationController
def new
attr_accessor :name, :email, :password
def initialize(attributes = {})
#name = attributes[:name]
#email = attributes[:email]
#password = attributes[:password]
end
def formatted_email
"#{#name} <#{#email}>"
end
end
Hey I'm following RoR too and come into the same problem. The trick here is your bundle exec rake db:migrate fails and therefore the password_digest column hasn't been added into the database. My console complains that database for User already exists. I delete the db/development.sqlite3 manully with "SQLite Browser". After running bundle exec rake db:migrate, every test passes

I'm new to rails, and I'm currently trying to develop an API based app using Rails 5, on one of my controllers I have a function to filter the allow parameters like so
def provider_params
params.require(:provider).permit(:name, :phone, :email, :website, :address, :provider_id, :bio, :specialty_ids => [])
end
Then posting from Paw I noticed that the arguments that are not attributes of the table are no included in provider_params, the parameter I'm supposed to receive is an array, which is defined by a HABTM relation-ship.
This is how my models look like
specialty.rb
class Specialty < ApplicationRecord
has_and_belongs_to_many :providers
end
provider.rb
class Provider < ApplicationRecord
has_and_belongs_to_many :specialties
end
And this is how the join table was created via migration
class CreateProvidersSpecialties < ActiveRecord::Migration[5.0]
def change
create_table :providers_specialties, :id => false do |t|
t.integer :provider_id
t.integer :specialty_id
end
add_index :providers_specialties, :provider_id
add_index :providers_specialties, :specialty_id
end
end
The JSON I'm posting
{
"name": "the name",
"specialty_ids": [
1,
2
]
}
So as I mentioned, the array specialty_ids doesn't seem to be coming through, and even if it did, I suspect there's still something else I need to do in order for rails to insert the content of specialty_ids in the ProvidersSpecialties Table
So the problem was finally solved by removing the requir call from the method provider_params, since I wasn't wrapping the json-payload in a provider key. Apparently once you add the require(:key) call you would only be able to add parameters that belong to the Model, which is weird since an error should be raised when the key is not present, what was the case with my payload, lacking the provider key.
Lets say if i want to generate and set default password for user while creating them in admin.
and i want to do something like this,
def user_params
params.require(:user).permit(:first_name, :last_name, :email, :password=> #default_generated_password, :password_confirmation => #default_generated_password)
end
I am using sorcery for User Authentication.
I am having a feeling that this is completely wrong way, But how do i do it?
You want to use reverse_merge (appeared in rails 5.1) or with_defaults (alias appeared in rails 5.2)
def user_params
params
.require(:user)
.permit(:first_name, :last_name, :email, :password, :password_confirmation)
.with_defaults(password: #default_generated_password, password_confirmation: #default_generated_password)
end
Merge them in after
params
.require(:user)
.permit(:first_name, :last_name)
.merge(password: #default_generated_password, password_confirmation: #default_generated_password)
Or if you need it just in one action (create for example)
def create
# password generation code...
# ...
#user = User.new(user_params.merge(password: #default_generated_password, password_confirmation: #default_generated_password))
if #user.save
redirect_to ...
else
flash[:error] = "Did not save"
render :new
end
end
private
def user_params
params.require(:user).permit(:first_name, :last_name)
end
Models:
A User has_one Ucellar
A Ucellar belongs_to User
I have confirmed from multiple sources that these are set up correctly. For posterity, here is the top portion of those two models.
class User < ActiveRecord::Base
has_many :authorizations
has_one :ucellar
validates :name, :email, :presence => true
This is actually the entire Ucellar model.
class Ucellar < ActiveRecord::Base
belongs_to :user
end
Ucellar has a column called user_id, which I know is necessary. The part of my application that creates a user uses the method create_with_oath. Below is the entire User class. Note the second line of the create method.
class User < ActiveRecord::Base
has_many :authorizations
has_one :ucellar
validates :name, :email, :presence => true
def create
#user = User.new(user_params)
#ucellar = #user.create_ucellar
end
def add_provider(auth_hash)
# Check if the provider already exists, so we don't add it twice unless authorizations.find_by_provider_and_uid(auth_hash["provider"], auth_hash["uid"])
Authorization.create :user => self, :provider => auth_hash["provider"], :uid => auth_hash["uid"]
end
end
def self.create_with_omniauth(auth)
user = User.create({:name => auth["info"]["name"], :email => auth["info"]["email"]})
end
private
def user_params
params.require(:user).permit(:name, :email)
end
end
EDIT:
Forgot to summarize the symptoms. On create, the user is in the db, with no exceptions thrown, and nothing to signify that anything went wrong. However, the related ucellar is never created. Per the documentation Here, the create method should create AND save the related ucellar.
It should create ucellar too.
Try to get the error messages after the creation by calling:
raise #user.errors.full_messages.to_sentence.inspect
I'm not sure why this wasn't working, but I ended up just moving this code out of the create action of the user controller, and putting it directly after an action that was creating a user. It solved my issue though. Thanks everyone for your help!
How to create migration to add the admin field to the users table with a boolean value and set default to false in Sinatra? I am using Active Record.
It's still just ActiveRecord, this would be no different than using it in Rails.
class AddAdminToUsers < ActiveRecord::Migration
def change
add_column :admin, :boolean, :default => false
end
end
You may also want to check out the sinatra-activerecord gem which will give you some extra rake tasks and makes things a little easier.
Here is also a useful article on using Sinatra with ActiveRecord.
Sinatra and ActiveRecord
I was having this problem too.
I solved it using change_table method instead of add_column so final code would look like:
class AddAdminToUsers < ActiveRecord::Migration
def change
change_table :users do |t|
t.column :admin, :boolean, default: false
end
end
end
-----UPDATE-----
Well, seems that the problem was in last.id. When database is created works OK, but when not fails. Now the question is different: How can I create a field using the id from the same row?
--------ORIGINAL------
I'm working with active record in pure ruby (without Rails), and I'm literally getting crazy with this.
This is my code
class Enviroment < ActiveRecord::Base
#self.table_name = 'enviroments'
self.connection.create_table(:enviroments, :force=>true) do |t|
t.column :name, :string, :default=>'env-'+ (last.id-1).to_s
t.column :ssh, :string, :default=>nil
end
end
and here the error:
ActiveRecord::StatementInvalid: Could not find table 'enviroments'
from /usr/lib/ruby/gems/1.8/gems/activerecord-3.2.3/lib/active_record/connection_adapters/sqlite_adapter.rb:465:in `table_structure'
if I useself.table_name = 'enviroments' still not working. I've updated the gems and neither.
I'm newbie with ruby and databases, but I can't understand this problem, I think this same code worked in the past :S
Your code to create the table (very odd to have that in the model by the way) is calling last.id, and of course to call last the table must already exist.
Because you're passing :force => true to create_table you'll actually destroy the table if it already exists.
You could probably make your code work if you stashed the value of last.id in a local variable before the call to create_table but I don't understand why you are creating tables like this.
Finally, this was my solution:
class Enviroment < ActiveRecord::Base
after_create :create_default
private
def create_default
if name == nil
s = 'env-' + self.id.to_s
self.name = s
self.save
end
end
end
class CreateSchema < ActiveRecord::Migration
create_table(:enviroments, :force=>true) do |t|
t.column :name, :string, :default=>nil
t.column :ssh, :string, :default=>nil
end
