我需要在html中返回calculate_c值
urls.py
from django.conf.urls import include, url
from . import views
urlpatterns = [
url(r'^$', views.my_view, name='my_view'),
]
views.py
from django.shortcuts import render
from django.http import HttpResponse
def abc():
a = 1
b = 3
calculate_c = a + b
return calculate_c
def my_view(request):
context = {'calculated_value': 0}
context['calculated_value'] = abc()
return HttpResponse(request, 'blog/post_list.html', context)
post_list.html
{% extends 'blog/base.html' %}
{% block content %}
<h2>{{calculated_value}}</h2>
<h2>Test</h2>
{% endblock %}

如果您需要模板中adc()
返回的值,则可以通过context
传递:
def my_view(request):
...
context = {...}
context['calculated_value'] = abc()
return render(request, 'blog/post_list.html', context)
然后在您的模板中,您可以使用:
{{ calculated_value }}

def abc():
return (lambda a, b: a+b)
calculate_c = abc()
calculate_c(1,3)
