#Folder to store factory boy django code

Some notes you do not need to read as to why I went with this option rather than proper solution to my question above. Self.nested_whatever_id = nested_object.id # then join nested_object to self via the self join Options_an_option=kwargs.get('an_option_for_a_nested_whatever', None)) # self is the top level object being options(self, create, not_used, **kwargs): Options_an_option_for_a_nested_whatever='abc')

So for a call such as: whatever = WhateverFactory(options_an_option='xyz', Because my desired models contained self joins, my factory is recursive.

# code for custom option 'another_option' Then this factory code detected the options and generated the test data required (note the method is renamed to options to match the prefix on the parameter names): options(self, create, not_used, **kwargs): I then extended this approach passing in options to configure the factory, like this: whatever = WhateverFactory(options_an_option=True, options_another_option=True) Parameter_lumn_id = column_ids_by_nameĮlif parameter_setting.name = 'income_in': # self is the `FunctionInstantiation` Django object just created by the `FunctionToParameterSettingsFactory` that contains this code.įor parameter_setting in self.parametersetting_set.all(): post(self, create, extracted, **kwargs):ĭict((column.name, column.id) for column in lumn_set.all()) The creation of dataset, column_1 and column_2 are moved into a new factory DatasetAnd2ColumnsFactory, and the code below is then added to the end of FunctionToParameterSettingsFactory. The naming in this question is easier to understand, so here is the same solution code for that sample problem: So it seems RelatedFactory calls are executed before PostGeneration calls. # self is the `Foo` Django object just created by the `ProblemFactory` that contains this code.įor another_obj in self.anotherobject_set.all():Īnother_obj.attribute_id = sub_object_ids_by_code Sub_object_ids_by_code = dict((sbj.name, sbj.id) for sbj in object.subobject_set.all()) We move the creation of sub_object and object from ProblemFactory to ObjectWithSubObjectsFactory (and remove the exclude clause), and add the following code to the end of ProblemFactory. solution does genuinely pass a SubFactory(LazyAttribute('')) to RelatedFactory, however restrictions remained that meant this was not right for my situation. I solved this by simply calling factories within Strictly speaking this isn't a solution to the specific problem posed, but I explain below in great detail why this ended up being a better architecture. Object = factory.SubFactory(ObjectFactory, sub_object=sub_object)īecause if I then do: object2 = factory.SubFactory(ObjectFactory, sub_object=sub_object)Ī second sub_object is created, whereas I need both objects to refer to the same sub_object. I can't just put sub_object=sub_object into the ObjectFactory call, ie: sub_object = factory.SubFactory(SubObjectFactory) LazyAttribute throws the error: AttributeError: The parameter sub_object is unknown. The identical LazyAttribute call can no longer see factory_parent, and can only access AnotherObject values. The identical call to LazyAttribute fails here: class ProblemFactory(OKFactory):Īnother_object = factory.RelatedFactory(AnotherObjectFactory, 'foo', object=object) Sub_object=factory.LazyAttribute(lambda obj: obj.factory_parent.sub_object)) Object = factory.SubFactory(ObjectFactory, Sub_object = factory.SubFactory(SubObjectFactory) This works fine: class OKFactory(factory.DjangoModelFactory): This works fine.īut if I pass the object created to a RelatedFactory, LazyAttribute can no longer see the factory_parent and fails. This raises error Attribute-error: 'Client' object has no attribute '_default_manager'.īut from my console I verified if client has default manager using In : Client.I am using factory.LazyAttribute within a SubFactory call to pass in an object, created in the factory_parent. Now I was about to unit test the routes and started with creating instance using Factory boy class ClientFactory(DjangoModelFactory): I was able to create retrieve and list client objects. Phone_number = models.CharField(max_length=250, blank=False)Įmail = models.EmailField(blank=False, unique=True, null=False) My client Model from django.db import modelsįrom mtl_model import BaseModelįrom mtl_ import ProjectStatusĬlient_name = models.CharField(max_length=250, blank=False) Super(BaseModel, self).save(*args, **kwargs) Updated_at = models.DateTimeField(editable=False) created_at = models.DateTimeField(editable=False) I have an Abstract model called base_model which is inherited by all other models of the project.

I am using factory boy to create test instances. I am using Django Rest Framework to create some api's.
