Graphene-Django comes with mutation classes that will convert the fields on Django forms into inputs on a mutation.
FormMutation
------------
..code:: python
class MyForm(forms.Form):
name = forms.CharField()
class MyMutation(FormMutation):
class Meta:
form_class = MyForm
``MyMutation`` will automatically receive an ``input`` argument. This argument should be a ``dict`` where the key is ``name`` and the value is a string.
ModelFormMutation
-----------------
``ModelFormMutation`` will pull the fields from a ``ModelForm``.
..code:: python
class Pet(models.Model):
name = models.CharField()
class PetForm(forms.ModelForm):
class Meta:
model = Pet
fields = ('name',)
# This will get returned when the mutation completes successfully
class PetType(DjangoObjectType):
class Meta:
model = Pet
class PetMutation(ModelFormMutation):
class Meta:
form_class = PetForm
``PetMutation`` will grab the fields from ``PetForm`` and turn them into inputs. If the form is valid then the mutation
will lookup the ``DjangoObjectType`` for the ``Pet`` model and return that under the key ``pet``. Otherwise it will
return a list of errors.
You can change the input name (default is ``input``) and the return field name (default is the model name lowercase).
..code:: python
class PetMutation(ModelFormMutation):
class Meta:
form_class = PetForm
input_field_name = 'data'
return_field_name = 'my_pet'
Form validation
---------------
Form mutations will call ``is_valid()`` on your forms.
