我想将一个变量从views.py传递给home.html。 我尽力了,对django还是陌生的。
它不会给出任何错误,但也不会显示该变量。 我可能在url.py或settings.py
中犯了错误settings.py

return render(request, 'templates/home.html', context)
home.html
<h>hello</h>
<h3>{{key}}</h3>
页面虽然显示问候,但没有显示{{key}} 这只是尝试尝试是否有效,但不适用于我。

您以错误的方式传递了templates
,并且使基于类的视图与基于函数的视图相混淆。
urls.py
from project1.views import index
urlpatterns = [
path('admin/', admin.site.urls),
path('', index, name='home'),
]
,然后在视图中只需通过'home.html'
。
views.py
from django.shortcuts import render
def index(request):
name = "kiran"
key = 123
context = {
'name': name,
'key': key,
}
return render(request, 'home.html', context)
现在应该可以正常工作了。

替换
urlpatterns = [
path('admin/', admin.site.urls),
path('', TemplateView.as_view(template_name='home.html'), name='home'),
]
使用
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.index, name='home'),
]
您的代码大部分是正确的,但是URL并未调用您的视图函数(在您的情况下为index
)。它使用带有home.html
模板的基于类的视图。

问题可能出在您导入的方式上
尝试导入诸如from project1 import views
之类的视图,然后将此path('', TemplateView.as_view(template_name='home.html'), name='home')
更改为path('', views.index, name='home')
