Rails: Difference between create and new methods in ActiveRecord?
What's the difference between these two lines?
first_page = Page.new(:name => "First page") first_page = Page.create(:name => "First page")
By the way, this is great tutorial; I recommend it for any other newbies like me.
Basically the new method creates an object instance and the create method additionally tries to save it to the database if it is possible.
Check the ActiveRecod::Base documentation:
create method 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.
new method New objects can be instantiated as either empty (pass no construction parameter) or pre-set with attributes but not yet saved (pass a hash with key names matching the associated table column names).
