Question

我正在尝试测试内部共享Python软件包中没有django 设置文件的自定义字段（因为没有django应用）。运行测试时，出现以下错误。

tests/test_fields.py:3: in <module>
    from rest_framework.validators import ValidationError
../../../.virtualenvs/myenv/lib/python3.6/site-packages/rest_framework/validators.py:14: in <module>
    from rest_framework.compat import unicode_to_repr

    from django.contrib.postgres import fields as postgres_fields

    from .array import *  # NOQA

    class SearchVector(SearchVectorCombinable, Func):
../../../.virtualenvs/myenv/lib/python3.6/site-packages/django/contrib/postgres/search.py:50: in SearchVector
    _output_field = SearchVectorField()
../../../.virtualenvs/myenv/lib/python3.6/site-packages/django/db/models/fields/__init__.py:172: in __init__
    self.db_tablespace = db_tablespace or settings.DEFAULT_INDEX_TABLESPACE
../../../.virtualenvs/myenv/lib/python3.6/site-packages/django/conf/__init__.py:56: in __getattr__
    self._setup(name)
../../../.virtualenvs/myenv/lib/python3.6/site-packages/django/conf/__init__.py:39: in _setup
    % (desc, ENVIRONMENT_VARIABLE))
E   django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

是否有抑制加载设置的需求？我只是试图测试该字段的逻辑。

class FMIDField(Field):

    VALID_CHARS = '[a-zA-Z0-9]{8}'

    default_error_messages = {
        'invalid_type': 'FMID must be a string',
        'invalid_characters': 'FMID must be 8 characters long and consist only of a-z, A-Z and 0-9'
    }

    def is_valid_chars(self, data):
        prog = re.compile(self.VALID_CHARS)
        return prog.fullmatch(data)

    def to_internal_value(self, data):
        if not isinstance(data, str):
            self.fail('invalid_type')

        if not self.is_valid_chars(data):
            self.fail('invalid_characters')

        return data

    def to_representation(self, value):
        return value

编辑为清楚起见

正在编写和测试的python软件包没有Django设置模块，因为它应该在Django应用程序中使用。

您应在文件中包含以下行

import os

import django

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "PROJECT_NAME.settings")
django.setup()
