#### Raising validation errors
|
||||
|
||||
Our `ColorField` class above currently does not perform any data validation.
|
||||
To indicate invalid data, we should raise a `serializers.ValidationError`, like so:
|
||||
|
||||
def to_internal_value(self, data):
|
||||
if not isinstance(data, six.text_type):
|
||||
msg = 'Incorrect type. Expected a string, but got %s'
|
||||
raise ValidationError(msg % type(data).__name__)
|
||||
|
||||
if not re.match(r'^rgb\([0-9]+,[0-9]+,[0-9]+\)$', data):
|
||||
raise ValidationError('Incorrect format. Expected `rgb(#,#,#)`.')
|
||||
|
||||
data = data.strip('rgb(').rstrip(')')
|
||||
red, green, blue = [int(col) for col in data.split(',')]
|
||||
|
||||
if any([col > 255 or col < 0 for col in (red, green, blue)]):
|
||||
raise ValidationError('Value out of range. Must be between 0 and 255.')
|
||||
|
||||
return Color(red, green, blue)
|
||||
|
||||
The `.fail()` method is a shortcut for raising `ValidationError` that takes a message string from the `error_messages` dictionary. For example:
|
||||
|
||||
default_error_messages = {
|
||||
'incorrect_type': 'Incorrect type. Expected a string, but got {input_type}',
|
||||
'incorrect_format': 'Incorrect format. Expected `rgb(#,#,#)`.',
|
||||
'out_of_range': 'Value out of range. Must be between 0 and 255.'
|
||||
}
|
||||
|
||||
def to_internal_value(self, data):
|
||||
if not isinstance(data, six.text_type):
|
||||
msg = 'Incorrect type. Expected a string, but got %s'
|
||||
self.fail('incorrect_type', input_type=type(data).__name__)
|
||||
|
||||
if not re.match(r'^rgb\([0-9]+,[0-9]+,[0-9]+\)$', data):
|
||||
self.fail('incorrect_format')
|
||||
|
||||
data = data.strip('rgb(').rstrip(')')
|
||||
red, green, blue = [int(col) for col in data.split(',')]
|
||||
|
||||
if any([col > 255 or col < 0 for col in (red, green, blue)]):
|
||||
self.fail('out_of_range')
|
||||
|
||||
return Color(red, green, blue)
|
||||
|
||||
This style keeps you error messages more cleanly separated from your code, and should be preferred.

#### Customizing ListSerializer initialization
|
||||
|
||||
When a serializer with `many=True` is instantiated, we need to determine which arguments and keyword arguments should be passed to the `.__init__()` method for both the child `Serializer` class, and for the parent `ListSerializer` class.
|
||||
|
||||
The default implementation is to pass all arguments to both classes, except for `validators`, and any custom keyword arguments, both of which are assumed to be intended for the child serializer class.
|
||||
|
||||
Occasionally you might need to explicitly specify how the child and parent classes should be instantiated when `many=True` is passed. You can do so by using the `many_init` class method.
|
||||
|
||||
@classmethod
|
||||
def many_init(cls, *args, **kwargs):

# Instantiate the child serializer.

This change also means that we no longer use the `.full_clean()` method on model instances, but instead perform all validation explicitly on the serializer. This gives a cleaner separation, and ensures that there's no automatic validation behavior on `ModelSerializer` classes that can't also be easily replicated on regular `Serializer` classes.
|
||||
|
||||
It's important to note that this change also means that the model `.clean()` method will not be called as part of serializer validation, as it would be if using a `ModelForm`. Use the serializer `.validate()` method to perform a final validation step on incoming data where required.
|
||||
For the most part this change should be transparent. Field validation and uniqueness checks will still be run as normal, but the implementation is a little different.
|
||||
|
||||
The one difference that you do need to note is that the `.clean()` method will not be called as part of serializer validation, as it would be if using a `ModelForm`. Use the serializer `.validate()` method to perform a final validation step on incoming data where required.
|
||||
|
||||
There may be some cases where you really do need to keep validation logic in the model `.clean()` method, and cannot instead separate it into the serializer `.validate()`. You can do so by explicitly instantiating a model instance in the `.validate()` method.

REST framework now has more explicit and clear control over validating empty values for fields.
|
||||
|
||||
Previously the meaning of the `required=False` keyword argument was underspecified. In practice its use meant that a field could either be not included in the input, or it could be included, but be `None` or the empty string.
|
||||
|
||||
We now have a better separation, with separate `required`, `allow_none` and `allow_blank` arguments.
|
||||
We now have a better separation, with separate `required`, `allow_null` and `allow_blank` arguments.
|
||||
|
||||
The following set of arguments are used to control validation of empty values:
|
||||
|
||||
* `required=False`: The value does not need to be present in the input, and will not be passed to `.create()` or `.update()` if it is not seen.
|
||||
* `default=<value>`: The value does not need to be present in the input, and a default value will be passed to `.create()` or `.update()` if it is not seen.
|
||||
* `allow_none=True`: `None` is a valid input.
|
||||
* `allow_null=True`: `None` is a valid input.
|
||||
* `allow_blank=True`: `''` is valid input. For `CharField` and subclasses only.
|
||||
|
||||
Typically you'll want to use `required=False` if the corresponding model field has a default value, and additionally set either `allow_none=True` or `allow_blank=True` if required.

||||
Typically you'll want to use `required=False` if the corresponding model field has a default value, and additionally set either `allow_null=True` or `allow_blank=True` if required.
|
||||
|
||||
The `default` argument is also available and always implies that the field is not required to be in the input. It is unnecessary to use the `required` argument when a default is specified, and doing so will result in an error.

Behavior for dealing with `OPTIONS` requests was previously built directly into the class based views. This has now been properly separated out into a Metadata API that allows the same pluggable style as other API policies in REST framework.

This makes it far easier to use a different style for `OPTIONS` responses throughout your API, and makes it possible to create third-party metadata policies.

## Miscellaneous notes

|

* The serializer `ChoiceField` does not currently display nested choices, as was the case in 2.4. This will be address as part of 3.1.
|
||||
* Due to the new templated form rendering, the 'widget' option is no longer valid. This means there's no easy way of using third party "autocomplete" widgets for rendering select inputs that contain a large number of choices. You'll either need to use a regular select or a plain text input. We may consider addressing this in 3.1 or 3.2 if there's sufficient demand.
