This reverts commit 4e9f53f9736544f070e75e516c71137b7eb49a7a, reversing
changes made to 6b802cdb4f5b84e1bf49aaeb0e994b3be6028af9.
Revert "Don't use tap in this case."
This reverts commit 454d820bf0a18fe1db4c55b0145197d70fef1f82.
Reason: Is not a good idea to add options to this method since we can do
the same thing using method composition.
Person.validators_on(:name).select { |v| v.kind == :presence }
Also it avoids to change the method again to add more options.
Due to a change in builder, nil values and empty strings now generates
closed tags, so instead of this:
<pseudonyms nil=\"true\"></pseudonyms>
It generates this:
<pseudonyms nil=\"true\"/>
Document this change in Rails so that people can track it down easily if
necessary.
- Enable propagation of :skip_types, :dasherize and :camelize on included models by default
- Adding the option to override this propagation on a per-include basis (:include => { :model => { :dasherize => false } }
- Enough tests to prove it works
- Updated activemodel CHANGELOG.md

ActiveRecord json/xml serialization should use as base
serializable_hash, provided by ActiveModel. Add some more coverage
around options :only and :except for both json and xml serialization.
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
When a model nests another model that also nests yet another model
using accepts_nested_attributes_for method, its Errors object can
have an attribute name with "contacts.addresses.street" style.
In this case, the dots within the namespace should be substituted
with slashes so that we can provide the translation under the
"activemodel.attributes.person/contacts/addresses.street" key.
This commit is related to #3859.
