If you call <tt>Product.find_by_sql</tt> then the results will be returned in - # a Product object with the attributes you specified in the SQL query. - # - # If you call a complicated SQL query which spans multiple tables the columns specified by the - # SELECT will be attributes of the model, whether or not they are columns of the corresponding - # table. - # - # The +sql+ parameter is a full SQL query as a string. It will be called as is, there will be - # no database agnostic conversions performed. This should be a last resort because using, for example, - # MySQL specific terms will lock you to using that particular database engine or require you to - # change your call if you switch engines. - # - # ==== Examples - # # A simple SQL query spanning multiple tables - # Post.find_by_sql "SELECT p.title, c.author FROM posts p, comments c WHERE p.id = c.post_id" - # > [#<Post:0x36bff9c @attributes={"title"=>"Ruby Meetup", "first_name"=>"Quentin"}>, ...] - # - # # You can use the same string replacement techniques as you can with ActiveRecord#find - # Post.find_by_sql ["SELECT title FROM posts WHERE author = ? AND created > ?", author_id, start_date] - # > [#<Post:0x36bff9c @attributes={"title"=>"The Cheap Man Buys Twice"}>, ...] - def find_by_sql(sql, binds = []) - connection.select_all(sanitize_sql(sql), "#{name} Load", binds).collect! { |record| instantiate(record) } - end - - # Creates an object (or multiple objects) and saves it to the database, if validations pass. - # The resulting object is returned whether the object was saved successfully to the database or not. - # - # The +attributes+ parameter can be either be a Hash or an Array of Hashes. These Hashes describe the - # attributes on the objects that are to be created. - # - # +create+ respects mass-assignment security and accepts either +:as+ or +:without_protection+ options - # in the +options+ parameter. - # - # ==== Examples - # # Create a single new object - # User.create(:first_name => 'Jamie') - # - # # Create a single new object using the :admin mass-assignment security role - # User.create({ :first_name => 'Jamie', :is_admin => true }, :as => :admin) - # - # # Create a single new object bypassing mass-assignment security - # User.create({ :first_name => 'Jamie', :is_admin => true }, :without_protection => true) - # - # # Create an Array of new objects - # User.create([{ :first_name => 'Jamie' }, { :first_name => 'Jeremy' }]) - # - # # Create a single object and pass it into a block to set other attributes. - # User.create(:first_name => 'Jamie') do |u| - # u.is_admin = false - # end - # - # # Creating an Array of new objects using a block, where the block is executed for each object: - # User.create([{ :first_name => 'Jamie' }, { :first_name => 'Jeremy' }]) do |u| - # u.is_admin = false - # end - def create(attributes = nil, options = {}, &block) - if attributes.is_a?(Array) - attributes.collect { |attr| create(attr, options, &block) } - else - object = new(attributes, options, &block) - object.save - object - end - end - - # Returns the result of an SQL statement that should only include a COUNT(*) in the SELECT part. - # The use of this method should be restricted to complicated SQL queries that can't be executed - # using the ActiveRecord::Calculations class methods. Look into those before using this. - # - # ==== Parameters - # - # * +sql+ - An SQL statement which should return a count query from the database, see the example below. - # - # ==== Examples - # - # Product.count_by_sql "SELECT COUNT(*) FROM sales s, customers c WHERE s.customer_id = c.id" - def count_by_sql(sql) - sql = sanitize_conditions(sql) - connection.select_value(sql, "#{name} Count").to_i - end - - # Attributes listed as readonly will be used to create a new record but update operations will - # ignore these fields. - def attr_readonly(*attributes) - self._attr_readonly = Set.new(attributes.map { |a| a.to_s }) + (self._attr_readonly || []) - end - - # Returns an array of all the attributes that have been specified as readonly. - def readonly_attributes - self._attr_readonly - end - - # If you have an attribute that needs to be saved to the database as an object, and retrieved as the same object, - # then specify the name of that attribute using this method and it will be handled automatically. - # The serialization is done through YAML. If +class_name+ is specified, the serialized object must be of that - # class on retrieval or SerializationTypeMismatch will be raised. - # - # ==== Parameters - # - # * +attr_name+ - The field name that should be serialized. - # * +class_name+ - Optional, class name that the object type should be equal to. - # - # ==== Example - # # Serialize a preferences attribute - # class User < ActiveRecord::Base - # serialize :preferences - # end - def serialize(attr_name, class_name = Object) - coder = if [:load, :dump].all? { |x| class_name.respond_to?(x) } - class_name - else - Coders::YAMLColumn.new(class_name) - end - - # merge new serialized attribute and create new hash to ensure that each class in inheritance hierarchy - # has its own hash of own serialized attributes - self.serialized_attributes = serialized_attributes.merge(attr_name.to_s => coder) - end - - # Guesses the table name (in forced lower-case) based on the name of the class in the - # inheritance hierarchy descending directly from ActiveRecord::Base. So if the hierarchy - # looks like: Reply < Message < ActiveRecord::Base, then Message is used - # to guess the table name even when called on Reply. The rules used to do the guess - # are handled by the Inflector class in Active Support, which knows almost all common - # English inflections. You can add new inflections in config/initializers/inflections.rb. - # - # Nested classes are given table names prefixed by the singular form of - # the parent's table name. Enclosing modules are not considered. - # - # ==== Examples - # - # class Invoice < ActiveRecord::Base - # end - # - # file class table_name - # invoice.rb Invoice invoices - # - # class Invoice < ActiveRecord::Base - # class Lineitem < ActiveRecord::Base - # end - # end - # - # file class table_name - # invoice.rb Invoice::Lineitem invoice_lineitems - # - # module Invoice - # class Lineitem < ActiveRecord::Base - # end - # end - # - # file class table_name - # invoice/lineitem.rb Invoice::Lineitem lineitems - # - # Additionally, the class-level +table_name_prefix+ is prepended and the - # +table_name_suffix+ is appended. So if you have "myapp_" as a prefix, - # the table name guess for an Invoice class becomes "myapp_invoices". - # Invoice::Lineitem becomes "myapp_invoice_lineitems". - # - # You can also overwrite this class method to allow for unguessable - # links, such as a Mouse class with a link to a "mice" table.
