BazaModels
An attempt to recreate 90% of the ActiveRecord functionality in a very simple way.
The examples in this readme actually work.
Relationships
has_many
class User < BazaModels::Model
has_many :roles
has_many :admin_roles, -> { where(role: "administrator") }, class_name: "Role", dependent: :restrict_with_error # :destroy-dependent also works
end
has_one
class User < BazaModels::Model
has_one :person, dependent: :restrict_with_error # :destroy-dependent also works
end
belongs_to
class Role < BazaModels::Model
belongs_to :user
end
Validations
Presence
class User < BazaModels::Model
validates :email, presence: true
end
Queries
Where
users = User.where(email: "myemail@example.com").to_a
Group
users = User.group(:email).to_a
Order
users = User.order(:email).to_a
Includes / autoloading / eager loading
users = User.includes(:roles)
Joins
users = User.joins(:roles).where(roles: {role: 'administrator'})
Other methods...
User.where(email: "myemail@example.com").to_sql #=> "SELECT `users`.* FROM..."
User.any? #=> true
User.all #=> BazaModels::Query<...>
User.select(:email)
User.limit(5)
User.to_enum
User.first
User.last
User.order(:id).reverse_order
Role.joins(:user).select("roles.*, users.email AS user_email").first.user_email #=> "test@example.com"
Ransack
Person.ransack(user_organization_name_cont: "test").result.to_a #=> [user]
Setting and saving attributes
Setting
role.assign_attributes(user: user, role: "administrator")
role.save! #=> true || raising error
role.update_attributes!(user: user, role: "administrator") #=> true || raising error
role.role = "administrator"
role.save #=> true || false
Getting
role.role #=> "administrator"
role.user #=> [some user]
role.has_attribute?(:created_at) #=> true
Contributing to baza_models
- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet.
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it.
- Fork the project.
- Start a feature/bugfix branch.
- Commit and push until you are happy with your contribution.
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
