已经发布了许多类似的问题,但我已经尝试过这些解决方案无济于事.我正在学习一个基本的Django教程,这是我的代码:

urls.py

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'tango_with_django_project.views.home', name='home'),
    # url(r'^tango_with_django_project/', include('tango_with_django_project.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),

    url(r'^rango/', include('rango.urls')), # ADD THIS NEW TUPLE!
)

views.py

from django.http import HttpResponse

def index(request):
    return HttpResponse("Rango says hello world!")

来自settings.py文件

ROOT_URLCONF = 'tango_with_django_project.urls'

希望你们都能帮助我开始

我正在研究Michael Hartl的Rails教程,我在第7.3.3节遇到了一个问题.我收到此错误消息:

ArgumentError in Users#new
Showing /Users/Anuraag/rails_projects/sample_app/app/views/users/new.html.erb where line #6 raised:
First argument in form cannot contain nil or be empty

当我运行以下rspec时:

bundle exec rspec spec/requests/user_pages_spec.rb -e "signup with invalid information"

在以下行:

<%= form_for(@user) do |f| %>

这是我的代码.如果我没有把它搞清楚,请告诉我如何改进这个问题:我对StackOverflow也很陌生

应用程序/视图/用户/ new.html.erb:

<% provide(:title, 'Sign up') %>
<h1>Sign up</h1>

<div class="row">
  <div class="span6 offset3">
    <%= form_for(@user) do |f| %>
      <%= render 'shared/error_messages' %>

      <%= f.label :name %>
      <%= f.text_field :name %>

      <%= f.label :email %>
      <%= f.text_field :email %>

      <%= f.label :password …
