如何在Django中覆盖外部应用模板？

问题描述

我尝试覆盖 django-recaptcha 模板，但没有任何运气。我究竟做错了什么？
我知道

另一种可能的解决方案

我现在注意到 captcha / includes / js_v2_checkbox.html 被 captcha / widget_v2_checkbox.html 。

我不确定 widget_v2_checkbox到底会发生什么.html 是从验证码模块中加载的...因此，我会将包括 widget_v2_checkbox.html 复制到项目的模板文件夹中。 / p>

为了保持一致性，您可能还决定将完整的 templates / captcha文件夹内容复制到项目中。

只要注意这些模板将来可能发生的变化升级验证码模块。

I tried overriding a django-recaptcha template without any luck. What am I doing wrong?I am aware of Override templates of external app in Django, but it is outdated. Thanks!

django-recaptcha file structure

Lib/
--site-packages/
----captcha/
------templates/
--------captcha/
----------includes/
------------js_v2_checkbox.html

my project file structure

project/
----templates/
--------captcha/
------------includes/
----------------js_v2_checkbox.html

settings.py

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

解决方案

You have two options:

(1) In your settings, rearrange INSTALLED_APPS as follows:

INSTALLED_APPS = [
    ...
    'project',
    ...
    'captcha',
    ...
]

since the template loader will look in the app’s templates directory following the order specified by INSTALLED_APPS, you're template will be found first.

or

(2) List project's templates folder in TEMPLATES[0]['DIRS'] as follows:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        ...
    },
]

Since, DIRS is searched before APP_DIRS, you're template will be found first.

Another possible solution

I notice now that captcha/includes/js_v2_checkbox.html is included by captcha/widget_v2_checkbox.html.

I'm not sure about what happens exactly when widget_v2_checkbox.html is loaded from captcha module ... so I would duplicate the "including" widget_v2_checkbox.html as well into your project's templates folder.

You might also decide to copy the full "templates/captcha" folder contents into you project, for consistency.

Just keep an eye on possibile future changes of those templates when upgrading the captcha module.
