我的项目名称是'trydjango19',我有两个应用程序:'newsletter'和'posts'。
trydjango19 / urls.py是:
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^posts/', include("posts.urls", namespace='posts')),
url(r'^', include("newsletter.urls", namespace='newsletter')),]
newsletter / urls.py是:
urlpatterns = [
url(r'^', 'newsletter.views.home', name='home'),]
newsletter / view.py是:
def home(request):
title = 'ОСТАВЬТЕ ЗАЯВКУ'
form = SignUpForm(request.POST or None)
context = {
"title": title,
"form": form
}
if form.is_valid():
instance = form.save(commit=False)
full_name = form.cleaned_data.get("full_name")
if not full_name:
full_name = "anonymous"
instance.full_name = full_name
instance.save()
context = {
"title": "Ваша заявка принята!"
}
if request.user.is_authenticated() and request.user.is_staff:
queryset = SignUp.objects.all().order_by('-timestamp')
context = {
"queryset": queryset
}
return render(request, "newsletter/home.html", context)
newsletter / templates / newsletter / home.html是:
{% extends 'newsletter/base.html' %}
{% load crispy_forms_tags %}
{% load staticfiles %}
{% block head_title %}Welcome | {{ block.super }}{% endblock %}
{% block jumbotron %}
{% if not request.user.is_authenticated %}
<img class="close" onclick="show('none')" src="{% static 'img/close.png' %}">
<p class='lead text-align-center'>{{ title }}</p>
<form method='POST' action=''>{% csrf_token %}
{{ form|crispy }}
<p class='text-align-center'>
<input class='btn btn-primary' type='submit' value='Откликнуться' />
</p>
</form>
</div>
<img src="{% static 'img/pony.png' %}" width='380px' />
... etc.
我尝试使用urls.py在很多方面,使用'namespace'和'app_name',但我仍然不明白它应该如何正常运行
In template /home/pavel/DJANG/django19/src/newsletter/templates/newsletter/home.html, error at line 0
Reverse for 'home' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []
答案 0 :(得分:5)
我猜测您在url
中使用了base.html
标记,类似于:
{% url 'home' %}
但是在主urls.py
文件中,您确定了urls.py
app中的子newsletter
文件的名称空间。
将此url
标记更改为以下内容:
{% url 'newsletter:home' %}
或从url(r'^', include("newsletter.urls", namespace='newsletter')),]
行中删除命名空间参数。
<强>注意:强>
设置home url模式的结尾更好,但这不会引发异常:
urlpatterns = [
url(r'^$', 'newsletter.views.home', name='home'),]
