问题描述

Template Loader 找到模板但模板没有加载

TemplateDoesNotExist at/cardpayment/cardpayment.html请求方式:GET请求地址:http://localhost:7000/cardpayment/Django 版本:1.8异常类型:TemplateDoesNotExist异常值:cardpayment.html异常位置:/home/sdr/sl/lib/python3.4/site-packages/django/template/loader.py in render_to_string, line 138Python 可执行文件:/home/sdr/sl/bin/pythonPython版本:3.4.3蟒蛇路径:['/home/sdr/sl/agryp','/home/sdr/pycharm-4.0.6/helpers/pydev','/home/sdr/sl/src/tastypie','/home/sdr/sl/agryp','/usr/local/lib/python34.zip','/usr/local/lib/python3.4','/usr/local/lib/python3.4/plat-linux','/usr/local/lib/python3.4/lib-dynload','/home/sdr/sl/lib/python3.4/site-packages']服务器时间:2015 年 5 月 5 日，星期二 10:17:40 +0000模板加载器事后分析Django 尝试按以下顺序加载这些模板:使用加载器 django.template.loaders.filesystem.Loader:/home/sdr/sl/agryp/templates/cardpayment.html(文件不存在)使用加载器 django.template.loaders.app_directories.Loader:/home/sdr/sl/agryp/agryp/templates/cardpayment.html(文件存在)<========== 文件存在但未加载/home/sdr/sl/src/tastypie/tastypie/templates/cardpayment.html(文件不存在)/home/sdr/sl/lib/python3.4/site-packages/grappelli/templates/cardpayment.html(文件不存在)/home/sdr/sl/lib/python3.4/site-packages/django/contrib/admin/templates/cardpayment.html(文件不存在)/home/sdr/sl/lib/python3.4/site-packages/django/contrib/auth/templates/cardpayment.html(文件不存在)/home/sdr/sl/lib/python3.4/site-packages/oauth2_provider/templates/cardpayment.html(文件不存在)/home/sdr/sl/lib/python3.4/site-packages/selectable/templates/cardpayment.html(文件不存在)

可以清楚地看到，加载程序能够找到模板.

settings.py 中的 TEMPLATE_DIRS 值如下:

TEMPLATES = [{'后端':'django.template.backends.django.DjangoTemplates'，'DIRS': [ os.path.join(BASE_DIR, "templates"),],'APP_DIRS':是的，'选项': {上下文处理器":['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.

代码检查出 0 个错误/警告.

cardpayment.html 的内容

{% 扩展 "base.html" %}{% block title %}电话卡支付{% endblock %}{% 阻止额外的头 %}{% 加载 selectable_tags %}{% include_ui_theme %}{% 结束块 %}{% 块内容 %}<h1>接收卡支付</h1><form name="paymentType" id="paymentType" class="form-horizo​​ntal"><字段集><label>检查客户类型<input type="radio" value="existing">现有客户<br/><input type="radio" value="new">Nee Customer<br/></fieldset></表单><div class="row"><form class="form-horizo​​ntal"><table class="table-responsive table-bordered">{{ form.as_table }}</表单>

{% 结束块 %}

解决方案

我遇到了同样的问题，有效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 = [{'后端':'django.template.backends.django.DjangoTemplates'，'目录':['模板']，'APP_DIRS':是的，'选项': {上下文处理器":['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",],},},

]

Template Loader finds the template but template is not loaded

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)

As it can be clearly seen, the loader is able to find the template.

The TEMPLATE_DIRS value in settings.py is as follows:

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',
            ],
        },
    },
]

I have tried to move the template to project/templates directory as well but the error persists.

Code checks out with 0 errors/warnings.

contents of cardpayment.html

{% 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 %}

解决方案

i've been running into the same problem, the solution that work was to specify my template directory (projects/templates) in templates settings like this:

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",
        ],
    },
},

]
