Template-loader postmortem

Django tried loading these templates, in this order:

    Using loader django.template.loaders.filesystem.Loader:
        /home/sdr/sl/agryp/templates/cardpayment.html (File does not exist)
    Using loader django.template.loaders.app_directories.Loader:
        /home/sdr/sl/agryp/agryp/templates/cardpayment.html (File exists) <=========== FILE EXISTS BUT NOT LOADED
        /home/sdr/sl/src/tastypie/tastypie/templates/cardpayment.html (File does not exist)
        /home/sdr/sl/lib/python3.4/site-packages/grappelli/templates/cardpayment.html (File does not exist)
        /home/sdr/sl/lib/python3.4/site-packages/django/contrib/admin/templates/cardpayment.html (File does not exist)
        /home/sdr/sl/lib/python3.4/site-packages/django/contrib/auth/templates/cardpayment.html (File does not exist)
        /home/sdr/sl/lib/python3.4/site-packages/oauth2_provider/templates/cardpayment.html (File does not exist)
        /home/sdr/sl/lib/python3.4/site-packages/selectable/templates/cardpayment.html (File does not exist)

可以清楚地看到,加载器能够找到模板.

settings.py中的TEMPLATE_DIRS值如下:

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',
                'allauth.account.context_processors.account',
                'allauth.socialaccount.context_processors.socialaccount',
            ],
        },
    },
]

我也尝试将模板移动到project/templates目录,但错误仍然存​​在.

代码检出0错误/警告.

cardpayment.html的内容

{% extends "base.html" %}
{% block title %}Card Payments over Phone{% endblock %}
{% block extrahead %}
    {% load selectable_tags %}
    {% include_ui_theme %}
{% endblock %}

{% block content %}
    <h1>Receive Card Payment</h1>
    <form name="paymentType"  id="paymentType" class="form-horizontal">
    <fieldset>
        <label>Check type of Customer
        <input type="radio" value="existing">Existing Customer<br />
        <input type="radio"  value="new">Nee Customer<br />
        </label>
    </fieldset>
    </form>

    <div class="row">
    <form class="form-horizontal">
        <table class="table-responsive table-bordered">
            {{ form.as_table }}
        </table>
    </form>
    </div>
{% endblock %}

Answer 1

我一直遇到同样的问题,工作的解决方案是在模板设置中指定我的模板目录(项目/模板),如下所示:

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': ['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',
            "django.core.context_processors.media",
        ],
    },
},

]

Answer 2

TemplateDoesNotExist... cardpayment.html可能意味着 Django can't find cardpayment.html，或者它可能意味着它可以找到 cardpayment.html 没问题，但无法在其中找到一些 {% include 'cardpayment_subsection.html' %}。

解释：

我刚刚在一个已经工作多年的项目中遇到了这个错误，这里的其他解决方案对我没有帮助。

我cardpayment.html 被模板加载器找到，但包含一些废话，这意味着它无法呈现。错误消息误导我认为 Django 不知道该文件存在，而实际上它知道它存在，只是无法成功呈现它。

有一段时间一切正常：cardpayment.html渲染没有问题。

视图.py

def cardpaymentview(request):            
    return render_to_response("cardpayment.html", {
            "message": "Hi SO"
            }, context_instance=RequestContext(request))

突然，即使我没有编辑cardpayment.html，我也收到了这个错误：

TemplateDoesNotExist at /cardpaymentpage: cardpayment.html

Using loader django.template.loaders.app_directories.Loader:
folder/lib/python2.7/site-packages/django/contrib/admin/templates/cardpayment.html (File does not exist)
folder/project/app1/templates/cardpayment.html (File does not exist)
folder/project/app2/templates/cardpayment.html (File does not exist)
folder/project/paymentapp/templates/cardpayment.html (File exists)

问题是我cardpayment.html又include调用了另一个模板：

{% include 'cardpayment_subsection.html' %}

我通过将文件重命名为而不进行编辑cardpayment_subsection.html来创建错误，因此该命令自然失败。something_else.htmlcardpayment.htmlinclude

但是正如您所看到的，调试消息并没有表明问题是调用cardpayment_subsection.html（文件不再存在）。

总结：如果其他解决方案对您不起作用，请尝试创建一个cardpayment2.html简单地说“Hello world”的测试文件，看看您是否至少可以渲染它。也许cardpayment.html正在读取文件，但其中有错误。（就我而言，我需要将 更改{% include '____.html' %}为引用实际存在的文件！）

Answer 3

找到了修复方法。我不知道为什么，但新的 TEMPLATES 指令（Django 1.8+）似乎不起作用。我将其注释掉并放入旧样式

TEMPLATE_DIRS = (
    '/home/sdr/sl/agryp/templates/',
 )

指令，一切又开始运转。啊啊！

需要弄清楚为什么新的 TEMPLATES 指令给我带来了问题。

感谢您尝试帮助大家！
