class Her::Model::OrmAdapter
Public Instance Methods
Get a list of column/property/field names
# File lib/orm_adapter/her/adapter.rb, line 23 def column_names klass.model_attributes end
Create a model using attributes
# File lib/orm_adapter/her/adapter.rb, line 75 def create!(attributes = {}) klass.create(attributes) end
Destroy an instance by passing in the instance itself.
# File lib/orm_adapter/her/adapter.rb, line 80 def destroy(object) object.destroy if valid_object?(object) end
Find all models, optionally matching conditions, and specifying order @see OrmAdapter::Base#find_first for how to specify order and conditions
# File lib/orm_adapter/her/adapter.rb, line 69 def find_all(options = {}) conditions, order = extract_conditions!(options) klass.where(conditions).all end
Find the first instance, optionally matching conditions, and specifying order
You can call with just conditions, providing a hash
User.to_adapter.find_first :name => "Fred", :age => 23
Or you can specify :order, and :conditions as keys
User.to_adapter.find_first :conditions => {:name => "Fred", :age => 23} User.to_adapter.find_first :order => [:age, :desc] User.to_adapter.find_first :order => :name, :conditions => {:age => 18}
When specifying :order, it may be
-
a single arg e.g.
:order => :name
-
a single pair with :asc, or :desc as last, e.g.
:order => [:name, :desc]
-
an array of single args or pairs (with :asc or :desc as last), e.g.
:order => [[:name, :asc], [:age, :desc]]

Get an instance by id of the model. Returns nil if a model is not found. This should comply with ActiveModel#to_key API, i.e.:
User.to_adapter.get(@user.to_key) == @user
# File lib/orm_adapter/her/adapter.rb, line 41 def get(id) klass.find(klass.primary_key => wrap_key(id)) end
Get an instance by id of the model. Raises an error if a model is not found. This should comply with ActiveModel#to_key API, i.e.:
User.to_adapter.get!(@user.to_key) == @user
# File lib/orm_adapter/her/adapter.rb, line 32 def get!(id) klass.find(klass.primary_key => wrap_key(id)) || raise(ArgumentError, "#{klass.name} not found with #{klass.primary_key} of #{wrap_key(id)}") end
