I am trying to create a Active Record tableless Model. My user.rb looks like this
class User < ActiveRecord::Base
class_inheritable_accessor :columns
def self.columns
@columns ||= [];
end
def self.column(name, sql_type = nil, default = nil, null = true)
columns << ActiveRecord::ConnectionAdapters::Column.new(
name.to_s,
default,
sql_type.to_s,
null
)
end
column :name, :text
column :exception, :text
serialize :exception
end
When creating the new object in controller
@user = User.new
I am getting the error
Mysql2::Error: Table 'Sampledb.users' doesn't exist: SHOW FIELDS FROM users
class Tableless
include ActiveModel::Validations
include ActiveModel::Conversion
extend ActiveModel::Naming
def self.attr_accessor(*vars)
@attributes ||= []
@attributes.concat( vars )
super
end
def self.attributes
@attributes
end
def initialize(attributes={})
attributes && attributes.each do |name, value|
send("#{name}=", value) if respond_to? name.to_sym
end
end
def persisted?
false
end
def self.inspect
"#<#{ self.to_s} #{ self.attributes.collect{ |e| ":#{ e }" }.join(', ') }>"
end
end
