)StreamBlockFactory can be used in conjunction with the other block
factory types to create complex, nested StreamValues, much like how
StreamBlock can be used to declare the blocks for a complex
StreamField.
First, define your StreamBlockFactory subclass, using
factory.SubFactory to wrap child block declarations. Be sure to
include your StreamBlock subclass as the model attribute on the inner
Meta class.
class MyStreamBlockFactory(wagtail_factories.StreamBlockFactory):
my_struct_block = factory.SubFactory(MyStructBlockFactory)
class Meta:
model = MyStreamBlockThen include your StreamBlockFactory subclass on a model factory as
the argument to a StreamFieldFactory.
class MyPageFactory(wagtail_factories.PageFactory):
body = wagtail_factories.StreamFieldFactory(MyStreamBlockFactory)
class Meta:
model = MyPageYou can then use a modified version of factory_boy's deep object
declaration syntax to build up StreamValues on the fly.
MyPageFactory(
body__0__my_struct_block__some_field="some value",
body__0__my_struct_block__some_other_field="some other value",
)To generate the default value for a block factory, terminate your declaration at the index and provide the block name as the value.
MyPageFactory(body__0="my_struct_block")Prior to version 3.0, StreamFieldFactory could only be used by
providing a dict mapping block names to block factory classes as the
single argument, for example:
class MyTestPageWithStreamFieldFactory(wagtail_factories.PageFactory):
body = wagtail_factories.StreamFieldFactory(
{
"char_array": wagtail_factories.ListBlockFactory(
wagtail_factories.CharBlockFactory
),
"int_array": wagtail_factories.ListBlockFactory(
wagtail_factories.IntegerBlockFactory
),
"struct": MyBlockFactory,
"image": wagtail_factories.ImageChooserBlockFactory,
}
)
class Meta:
model = models.MyTestPageThis style of declaration is still supported, with the caveat that
nested stream blocks are not supported for this approach. From version
3.0, all BlockFactory values in a StreamFieldFactory definition of
this style must be wrapped in factory_boy SubFactories. For
example, the above example must be updated to the following for 3.0
compatibility.
class MyTestPageWithStreamFieldFactory(wagtail_factories.PageFactory):
body = wagtail_factories.StreamFieldFactory(
{
"char_array": wagtail_factories.ListBlockFactory(
wagtail_factories.CharBlockFactory
),
"int_array": wagtail_factories.ListBlockFactory(
wagtail_factories.IntegerBlockFactory
),
"struct": factory.SubFactory(MyBlockFactory),
"image": factory.SubFactory(wagtail_factories.ImageChooserBlockFactory),
}
)
class Meta:
model = models.MyTestPageThis requirement does not apply to ListBlockFactory, which is a
subclass of SubFactory.
