EasyModel provides features of database independent attribute. You can define the attribute like ActiveRecord that perform data conversion during assignment.
First, include EasyModel to your model. Next define attribute by `column` method.
class LoginForm include EasyModel::Column column :member_no, :integer column :password, :string column :remember, :boolan, default: false end
When you assign a value to attribute defined by `column` method, a value is converted to attribute's data type (like ActiveRecord).
login_form = LoginForm.new(:member_no => '1234567', :password => 'PASSWORD', :remember => 'false') login_form.member_no # => 1234567 login_form.member_no_before_type_cast # => '1234567' login_form.password # => 'PASSWORD' login_form.password_before_type_cast # => 'PASSWORD' login_form.remember # => false login_form.remember_before_type_cast # => 'false'
EasyModel uses I18n to internationalization. By default, the look up key is `<locale>.easy_model`.
en: easy_model: models: login_form: Login form attributes: login_form: member_no: Member number password: Password remember: Keep the login state.
By define the `i18n_scope` method, you can change the look up key. For example, to use the look up key same as ActiveRecord:
class LoginForm include EasyModel::Column def self.i18n_scope :activerecord end end
EasyModel::SearchForm is useful to create search form model. EasyModel::SearchForm includes EasyModel::Column, and provides useful features to searching. Only define the `scoped` method, you can use query method same as ActiveRecord.
class UserSearchForm < EasyModel::SearchForm column :name, :string column :status, :integer validates :status, :inclusion => [1, 2, 3] def scoped scoped = User.all # Add to conditions if value is present. scoped = scoped.where(:name => name) if self.name.present? scoped = scoped.where(:status => status) if self.status.present? # Return scope including search conditions. scoped end end
Query methods (i.e. find, all, …) is delegated to `scoped` method. So, you can use the interface same as ActiveRecord::Relation.
user_search_form = UserSearchForm.new(params[:user_search_form]) if user_search_form.valid? users = user_search_form.all else ... end
