When a user cancels their account on my application their user record is correctly removed from the database but their profile record still seems to exist. Below are my models for user and profile, any solutions?
Profile.rb
class Profile < ActiveRecord::Base
belongs_to :user
end
user.rb
class User < ActiveRecord::Base
has_one :profile
#callback that creates a profile for each user that signs up
after_create :create_profile
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
private
def create_profile
self.profile = Profile.create
end
end
You have to specify explicitly what to do with dependent model.
As example
has_one :profile, dependent: :destroy
There are some other options like :delete, :nullify. You can take a look at them here: http://apidock.com/rails/ActiveRecord/Associations/ClassMethods/has_one
It will also delete the association too.
has_one :profile, dependent: :destroy

I am using rails 5.0.0.1
When I submit a form, validations for associated fields are coming into action.
I have Gig, User, Category and other models
I am using devise for user authentication
Gig model
class Gig < ActiveRecord::Base
has_many :proposals
belongs_to :category
has_many :abilities
has_many :skills, through: :abilities
belongs_to :user
end
User model
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :gigs
has_many :proposals
end
Category model
class Category < ActiveRecord::Base
has_many :gigs
end
When I try to create the gig in console, the transaction rolls back.
the error messages are
["Category must exist", "User must exist"]
I appreciate your help. Thanks in advance.
In rails 5 when you add belongs_to it makes this field required. Try this
belongs_to :user, optional: true
I have three models and here they are when I try to create a has_many. I basically want my users (using devise) to have many categories. And categories to have many users.
user.rb
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable,
:omniauthable
has_many :user_categories
has_many :categories, through: :user_categories
acts_as_messageable
def mailboxer_email(object)
email
end
end
userCategory.rb
class UserCategory < ActiveRecord::Base
belongs_to :user
belongs_to :category
accepts_nested_attributes_for :categories
end
Category.rb
class Category < ActiveRecord::Base
has_many :user_categories
has_many :user, through: :user_categories
validates :name, presence: true, length: {minimum: 3, maximum: 25}
validates_uniqueness_of :name
end
when I run category.users << user I get this error:
ActiveRecord::HasManyThroughAssociationNotFoundError: Could not find the association :user_categories in model Category
I can't say for sure what the problem could be, but a few things I could point out:
UserCategory's accepts_nested_attributes_for, does that mean the you want to be able to dynamically create categories?
Category has_many :users, through: :user_categories, not user
You need to follow the Rails file naming conventions, user.rb, user_category.rb and category.rb
These may not be the problem/solution, but I believe they're in the way of resolving the problem.
I want to make audits for nested associations like I have
User has_many addresses i.e either
HomeAddress or OfficeAddress
Now if I have just one table Address and I have used type and id for differentiating them.In this case if I use associated_audits for User then it will make just one audit record and whenever I update the record again ,its just replacing the previous audit with the last one.
Here is the models association:
class Patient < ActiveRecord::Base
devise :database_authenticatable, :registerable, :recoverable, :rememberable,
:trackable, :validatable, :confirmable, request_keys: [:subdomain]
has_one :home_address,-> { where(addr_type: 'home') },class_name: 'Address'
has_one :office_address,-> { where(addr_type: 'office') }, class_name: 'Address'
has_associated_audits
accepts_nested_attributes_for :home_address, allow_destroy: true
accepts_nested_attributes_for :office_address, allow_destroy: true
end
class Address < ActiveRecord::Base
belongs_to :patient
audited
end
class Address < ActiveRecord::Base
belongs_to :patient
audited associated_with: :patient
end
class Patient < ActiveRecord::Base
has_many :addresses
has_associated_audits
end
I have devise model User
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
belongs_to :meta, polymorphic: true
end
And two types of users that have a polymorphic association to the User model:
class Admin < ActiveRecord::Base
has_one :user, as: :meta, dependent: :destroy
accepts_nested_attributes_for :user
end
class Guest < ActiveRecord::Base
has_one :user, as: :meta, dependent: :destroy
accepts_nested_attributes_for :user
end
Admin's password must have minimum 10 symbols length.
Guest's password must have minimum 6 symbols length.
How I can set different password length for each model, using devise or any different way?
I am working on a Rails app where a User can create a magazine and another user can subscribe to that magazine. I want to know the best way to do this.
Currently I have a subscription model that builds from current user when created and users the current magazine as the magazine_id. This allow me to have a table of user_ids and magazine_ids. This allows me to see all the subscriptions but it means I cant easily check all the magazines someone subscribes to or check all the subscribers of a magazine.
When I try to use has_many :through, it throws up an error with building from current user. I have put in the relevant code below, hopefully it covers it all and thanks in advance.
User 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
has_many :magazines
has_many :subscriptions
end
Subscription model:
class Subscription < ActiveRecord::Base
belongs_to :user
belongs_to :magazine
end
Magazine model:
class Magazine < ActiveRecord::Base
belongs_to :user
has_many :subscrptions
has_many :users
end
The snippet of code from the subscription controller that throws up the error when I use has many through
def new
#subscription = current_user.subscriptions.build
#sub = Sub.find(params[:sub_id])
end
Hopefully that is enough for someone to figure out, if not please ask me for the other code or information.
You're very close, you're just missing the connection. Magazine can see Subscription because Subscription has its magazine_id. User can see Subscription because Subscription has its user_id. Through the Subscription, Magazine and User can see each other. So you want to user through
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :magazines, through: :subscriptions
has_many :subscriptions
end
class Subscription < ActiveRecord::Base
belongs_to :user
belongs_to :magazine
end
class Magazine < ActiveRecord::Base
belongs_to :user
has_many :subscriptions
has_many :users, through: :subscriptions
end
If this doesn't work, make sure you post your schema.rb/relevant fields from the tables you mentioned.
I think this should work, might need to set additional options though.
User 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
has_many :magazines
has_many :subscriptions
has_many :subscribed_magazines, through: :subscriptions, source: :magazine
end
Subscription model:
class Subscription < ActiveRecord::Base
belongs_to :user
belongs_to :magazine
end
Magazine model:
class Magazine < ActiveRecord::Base
belongs_to :user
has_many :subscriptions
has_many :subscribed_users, through: :subscriptions, source: :user
end
Edit: Needed source, not class_name
