Django错误:未配置DjangoTemplates后端 [英] Django Error: No DjangoTemplates backend is configured
问题描述
我正在使用Django,我需要根据给定的模板(lab.html)动态生成HTML文件:
I'm using Django and I need to dynamically generate an HTML file from a given template (lab.html):
from django.template import Template, Context
from django.conf import settings
settings.configure()
f = qc.QFile('lab.html')
f.open(qc.QFile.ReadOnly | qc.QFile.Text)
stream = qc.QTextStream(f)
template = stream.readAll()
print(template)
f.close()
t = Template(template)
c = Context({"result": "test"}) #result is the variable in the html file that I am trying to replace
但是,我不断发现这个奇怪的错误,经过一些研究我没有发现。有什么想法吗?
However, I keep getting this odd error that I haven't found anywhere after some research. Any thoughts?
Traceback (most recent call last):
File "/Users/gustavorangel/PycharmProjects/help/HelpUI.py", line 262, in filesSearch
t = Template(template)
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/template/base.py", line 184, in __init__
engine = Engine.get_default()
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/django/template/engine.py", line 83, in get_default
"No DjangoTemplates backend is configured.")
django.core.exceptions.ImproperlyConfigured: No DjangoTemplates backend is configured.
推荐答案
对于Django> 1.7您的 settings.py
,您应该在 TEMPLATES
列表中的 BACKEND
键中具有一些值。基本上,您应该在设置中添加类似的内容
For Django > 1.7 your settings.py
you should have some value for the BACKEND
key in the TEMPLATES
list. Basically you should have something like this in your settings
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'APP_DIRS': True,
'OPTIONS': {
# ... some options here ...
},
},
]
从文档开始:
BACKEND
是实现Django模板后端API的模板引擎类的虚线Python路径。内置的后端是 django.template.backends.django.DjangoTemplates
和 django.template.backends.jinja2.Jinja2
。
BACKEND
is a dotted Python path to a template engine class implementing Django’s template backend API. The built-in backends are django.template.backends.django.DjangoTemplates
and django.template.backends.jinja2.Jinja2
.
编辑:
要从命令行而不是使用 render
的视图加载模板方法,您必须做更多的工作。
To load templates from the command line rather than a view using the render
method, you have to do a little more work.
如果您不想使用磁盘上的模板,则可以使用以下命令:
If you don't want to use a template from disk, you can use the following:
from django.conf import settings
settings.configure()
from django.template import Template, Context
Template('Hello, {{ name }}!').render(Context({'name': 'world'}))
但是,如果要从磁盘加载模板,则需要付出更多努力。这样的东西将起作用:
However, if you want to load templates from disk, this requires more effort. Something like this will work:
import django
from django.conf import settings
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': ['/path/to/template'],
}
]
settings.configure(TEMPLATES=TEMPLATES)
django.setup()
from django.template.loader import get_template
from django.template import Context
template = get_template('my_template.html')
template.render(Context({'name': 'world'})
