Since we're dealing with a new array instance, it's safe to use map! and
we avoid an extra array object.
Also remove the symbolize_keys! from AttributeMethodMatcher, since it's
an internal class that always receives symbol keys from the prefix/suffix
methods implementations.
There's no need to create two extra hashes with options.merge(another_hash),
with the goal of setting only one value, so lets just set it.
Also refactor validates_each to use _merge_attributes, like other
validates_* helpers do.
These _define class methods don't need to be exposed to objects that
extend ActiveModel::Callbacks.
Also use merge! options to avoid the creation of an extra hash.
The keys of the error messages are actually attribute names. It makes
the documentation easier to understand:
# Returns +true+ if the error messages include an error for the given
# +attribute+, +false+ otherwise.
#
# person.errors.messages # => { :name => ["can not be nil"] }
# person.errors.include?(:name) # => true
# person.errors.include?(:age) # => false
def include?(attribute)
(v = messages[attribute]) && v.any?
end
* Moved the simplest case--enable/disable all on all--to the top.
* Made clear what "ORM" means to avoid having to teach people how to solve "uninitialized constant ORM"
errors in their test reports.
Changes:
* Update `include_root_in_json` default value to false for default value
to false for `ActiveModel::Serializers::JSON`.
* Remove unnecessary change to include_root_in_json option in
wrap_parameters template.
* Update `as_json` documentation.
* Fix JSONSerialization tests.
Problem:
It's confusing that AM serializers behave differently from AR,
even when AR objects include AM serializers module.
class User < ActiveRecord::Base; end
class Person
include ActiveModel::Model
include ActiveModel::AttributeMethods
include ActiveModel::Serializers::JSON
attr_accessor :name, :age
def attributes
instance_values
end
end
user.as_json
=> {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true}
# root is not included
person.as_json
=> {"person"=>{"name"=>"Francesco", "age"=>22}}
# root is included
ActiveRecord::Base.include_root_in_json
=> false
Person.include_root_in_json
=> true
# different default values for include_root_in_json
Proposal:
Change the default value of AM serializers to false, update
the misleading documentation and remove unnecessary change
to false of include_root_in_json option with AR objects.
class User < ActiveRecord::Base; end
class Person
include ActiveModel::Model
include ActiveModel::AttributeMethods
include ActiveModel::Serializers::JSON
attr_accessor :name, :age
def attributes
instance_values
end
end
user.as_json
=> {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true}
# root is not included
person.as_json
=> {"name"=>"Francesco", "age"=>22}
# root is not included
ActiveRecord::Base.include_root_in_json
=> false
Person.include_root_in_json
=> false
# same behaviour, more consistent
Fixes#6578.
Passing a falsey option value for a validator currently causes that validator to
be enabled, just like "true":
ActiveModel.validates :foo, :presence => false
This is rather counterintuitive, and makes it inconvenient to wrap `validates` in
methods which may conditionally enable different validators.
As an example, one is currently forced to write:
def has_slug(source_field, options={:unique => true})
slugger = Proc.new { |r| r[:slug] = self.class.sluggify(r[source_field]) if r[:slug].blank? }
before_validation slugger
validations = { :presence => true, :slug => true }
if options[:unique]
validations[:uniqueness] = true
end
validates :slug, validations
end
because the following reasonable-looking alternative fails to work as expected:
def has_slug(source_field, options={:unique => true})
slugger = Proc.new { |r| r[:slug] = self.class.sluggify(r[source_field]) if r[:slug].blank? }
before_validation slugger
validates :slug, :presence => true, :slug => true, :uniqueness => options[:unique]
end
(This commit includes a test, and all activemodel and activerecord tests pass as before.)
XmlMini define the xml 'datatime', but according to
http://www.w3.org/TR/xmlschema-2/#dateTime could be better
change this to 'dateTime' with upper case letter 'T.
So 'DateTime' and 'Time' are redefined from 'datetime' to 'dateTime'
add the changing to the changelog
