from django.contrib import admin
from .models import Question
class QuestionAdmin(admin.ModelAdmin):
    fields = ['pub_date', 'question_text']
admin.site.register(Question, QuestionAdmin)

一、静态文件

创建static在app的目录下，polls/static/。和建立templates类似，还需要在建立app名字命名的文件夹。将文件放于其下polls/static/polls/。

1.1 添加css

建立css文件夹，再建立style.css，写入：

1
2
3
li a {
    color: green;
}

修改index.html

1
2
{% load static %}
<link rel="stylesheet" type="text/css" href="{% static 'polls/css/style.css' %}" />

from django.utils import timezone
from django.test import TestCase
from .models import Question
class QuestionMethodTests(TestCase):
    def test_was_published_recently_with_future_question(self):
        """
        was_published_recently() should return False for questions whose
        pub_date is in the future.
        """
        time = timezone.now() + datetime.timedelta(days=30)
        future_question = Question(pub_date=time)
        self.assertIs(future_question.was_published_recently(), False)

在终端运行。

<h1>{{ question.question_text }}</h1>
{% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}
<form action="{% url 'polls:vote' question.id %}" method="post">
{% csrf_token %}
{% for choice in question.choice_set.all %}
    <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" />
    <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br />
{% endfor %}
<input type="submit" value="Vote" />
</form>

其中forloop.counter是指for循环了多少次。
