EasyModel provides features of database independent attribute. You can define the attribute like ActiveRecord that perform data conversion during assignment.
Define database independent attribute
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
