Django：在测试模式下以不同的方式定义表单

发布于 2024-10-04 12:37:57 字数 597 浏览 3 评论 0原文

我有一个自定义的验证码字段。我想在测试期间显示该字段时从表单中删除该字段。

我最初的想法是在单独的设置文件中添加一个 TESTING 变量，该变量将作为参数提供给测试运行器命令。然后，我可以这样说：

class CaptchaForm(forms.Form):
    notify_email = forms.EmailField(required=False)
    if not settings.TESTING:
        recaptcha = CaptchaField()

我相信这应该有效。

可能有更好的方法。有什么想法吗？

更新

在尝试了下面的建议后，我将其添加到测试文件夹的 __init__.py 中：

    from project.app.forms import CaptchaField
    CaptchaField.clean = lambda x, y: y

这有效——无需创建共享的 TESTING 设置。这看起来可以接受吗？我有理由不应该这样做吗？

I have a customized captcha field. I want to remove that field from a form when displaying it during tests.

My initial thought was to have a TESTING variable in a separate settings file that will be supplied as an argument to the test runner command. Then, I could to something like:

class CaptchaForm(forms.Form):
    notify_email = forms.EmailField(required=False)
    if not settings.TESTING:
        recaptcha = CaptchaField()

I believe this should work.

There might be an even better approach. Any ideas?

Update

After playing around with the suggestions below, I added this to the test folder's __init__.py:

    from project.app.forms import CaptchaField
    CaptchaField.clean = lambda x, y: y

This worked---without creating a shared TESTING setting. Does this look acceptable? Is there a reason that I should not do this?

您可以在单元测试类的构造函数中禁用验证码。像这样：

class MyTest(unittest.TestCase):
    def __init__(self, *args, **kwargs):
         super(MyTest, self).__init__(*args, **kwargs)
         settings.TESTING = True

或者例如，您可以在此构造函数中禁用验证码字段验证。

You can disable captcha in constructor of unit-testing class. Like this:

class MyTest(unittest.TestCase):
    def __init__(self, *args, **kwargs):
         super(MyTest, self).__init__(*args, **kwargs)
         settings.TESTING = True

Or you can disable captcha field validation in this constructor, for example.

我假设 CaptchaField 是您自己的类。然后您可以更改验证方法：

from django.core.exceptions import ValidationError

class CaptchaField(Field):
    # ...

    def validate(self, value, model_instance):
        if settings.TESTING:
            return
        else:
            # Do CAPTCHA checking, leading to either
            # raise ValidationError  or
            # return

正如 were human 已经提到的，您实际上并不需要单独的设置文件，但可以更改单元测试类内的设置。

I assume CaptchaField is your own class. Then you could change the validation method:

from django.core.exceptions import ValidationError

class CaptchaField(Field):
    # ...

    def validate(self, value, model_instance):
        if settings.TESTING:
            return
        else:
            # Do CAPTCHA checking, leading to either
            # raise ValidationError  or
            # return

As werehuman already mentioned, you don't really need a separate settings file but can change the setting inside the unit test class.
