ArrayField missing 1 required positional argument

Question

I imported the following header file

from django.contrib.postgres.fields import ArrayField 

The following was used in the model:

 question_array = ArrayField(models.IntegerField, blank=True,) 

I get the following error

 Traceback (most recent call last) File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\__init__.py", line 27, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\apps\registry.py", line 108, in populate app_config.import_models(all_models) File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\apps\config.py", line 199, in import_models self.models_module = import_module(models_module_name) File "C:\Program Files (x86)\Python\Python35-32\lib\importlib\__init__.py", line 126, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 986, in _gcd_import File "<frozen importlib._bootstrap>", line 969, in _find_and_load File "<frozen importlib._bootstrap>", line 958, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 673, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 665, in exec_module File "<frozen importlib._bootstrap>", line 222, in _call_with_frames_removed File "C:\Users\DELL\Desktop\cstrom\comp\models.py", line 24, in <module> class User(models.Model): File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\db\models\base.py", line 157, in __new__ new_class.add_to_class(obj_name, obj) File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\db\models\base.py", line 316, in add_to_class value.contribute_to_class(cls, name) File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\db\models\fields\__init__.py", line 689, in contribute_to_class self.set_attributes_from_name(name) File "C:\Program Files (x86)\Python\Python35-32\lib\site-packages\django-1.10.4-py3.5.egg\django\contrib\postgres\fields\array.py", line 75, in set_attributes_from_name self.base_field.set_attributes_from_name(name) TypeError: set_attributes_from_name() missing 1 required positional argument: 'name' 

Answer 1

According to docs

You still need to fully define the field inside the array field

 question_array = ArrayField(models.IntegerField(null=True, blank=True), blank=True,) 

Answer 2

models.IntegerField is a function, not a property, so you will need to call it as a function. () at the end

 question_array = ArrayField(models.IntegerField(blank=True), blank=True,)
