Question

我写了一个Django Web应用程序，现在我需要将其翻译成英文。我遵循了documentation，但不断收到这个奇怪的错误：

在/ i18n / setlang / settings中配置不正确。DATABASES为   配置不正确。请提供引擎值。检查设定   文档以获取更多详细信息。请求方法：POST请求   URL：http://192.92.149.139:8000/i18n/setlang/ Django版本：2.0.3   异常类型：错误配置的异常值：

编辑：和设置。数据库：

{
    'default': {
        'ENGINE': 'django.db.backends.dummy',
        'ATOMIC_REQUESTS': False,
        'AUTOCOMMIT': True,
        'CONN_MAX_AGE': 0,
        'OPTIONS': {},
        'TIME_ZONE': None,
        'NAME': '',
        'USER': '',
        'PASSWORD': '',
        'HOST': '',
        'PORT': '',
        'TEST': {
            'CHARSET': None, 'COLLATION': None, 'NAME': None, 'MIRROR': None
        }
    }
}

这是我的urls.py：

urlpatterns = [
    path('i18n/',include('django.conf.urls.i18n')),
]

urlpatterns += i18n_patterns(
    path('admin/',admin.site.urls),
    path('',include('arquivo.urls')),
    prefix_default_language = True
)

和settings.py：

LANGUAGE_CODE = 'pt'    
LANGUAGES = (
    ('en', 'English'),
    ('pt', 'Portuguese'),
)
USE_I18N = True
LOCALE_PATHS = [
    os.path.join(BASE_DIR,'locale')
]

翻译似乎运行良好。问题是当我包括选择语言的表格时。我使用了documentation中的示例代码：

{% load i18n %}

<form action="{% url 'set_language' %}" method="post">{% csrf_token %}
    <input name="next" type="hidden" value="{{ redirect_to }}">
    <select name="language">
        {% get_current_language as LANGUAGE_CODE %}
        {% get_available_languages as LANGUAGES %}
        {% get_language_info_list for LANGUAGES as languages %}
        {% for language in languages %}
            <option value="{{ language.code }}"{% if language.code == LANGUAGE_CODE %} selected{% endif %}>
                {{ language.name_local }} ({{ language.code }})
            </option>
        {% endfor %}
    </select>
    <input type="submit" value="Go">
</form>

好，所以问题与会话有关。我正在使用带有Django-MongoEngine的MongoDB数据库，并且没有打开会话支持。因此，只需添加这两行代码

func ResizeImageOriginalSize(targetSize: CGSize) -> UIImage {
        var actualHeight: Float = Float(self.size.height)
        var actualWidth: Float = Float(self.size.width)
        let maxHeight: Float = Float(targetSize.height)
        let maxWidth: Float = Float(targetSize.width)
        var imgRatio: Float = actualWidth / actualHeight
        let maxRatio: Float = maxWidth / maxHeight
        var compressionQuality: Float = 0.5
        //50 percent compression

        if actualHeight > maxHeight || actualWidth > maxWidth {
            if imgRatio < maxRatio {
                //adjust width according to maxHeight
                imgRatio = maxHeight / actualHeight
                actualWidth = imgRatio * actualWidth
                actualHeight = maxHeight
            }
            else if imgRatio > maxRatio {
                //adjust height according to maxWidth
                imgRatio = maxWidth / actualWidth
                actualHeight = imgRatio * actualHeight
                actualWidth = maxWidth
            }
            else {
                actualHeight = maxHeight
                actualWidth = maxWidth
                compressionQuality = 1.0
            }
        }
        let rect = CGRect(x: 0.0, y: 0.0, width: CGFloat(actualWidth), height: CGFloat(actualHeight))
        UIGraphicsBeginImageContextWithOptions(rect.size, false, CGFloat(compressionQuality))
        self.draw(in: rect)
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return newImage!
    }

到SESSION_ENGINE = 'django_mongoengine.sessions' SESSION_SERIALIZER = 'django_mongoengine.sessions.BSONSerializer'，一切开始正常。

Django“ settings.DATABASES配置不正确”和“ / i18n / setlang /配置不正确”
