django - 卡在 "Practical Django Projects"

Question

本教程出现另一个错误。我应该放弃并转向另一个吗？ …
无论如何..这里是:

这是网址:

from django.conf.urls.defaults import *

from coltrane.models import Entry

entry_info_dict = {
    'queryset': Entry.objects.all(),
    'date_field': 'pub_date',
}

urlpatterns = patterns('django.views.generic.date_based',
    (r'^$', 'archive_index', entry_info_dict, 'coltrane_entry_archive_index'),

    (r'^(?P<year>\d{4})/$', 'archive_year', entry_info_dict, 'coltrane_entry_archive_year'),

    (r'^(?P<year>\d{4})/(?P<month>\w{3})/$', 'archive_month', entry_info_dict, 'coltrane_entry_archive_month'),

    (r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/$', 'archive_day', entry_info_dict, 'coltrane_entry_archive_day'),

    (r'^(?P<year>\d{4})/(?P<month>\w{3})/(?P<day>\d{2})/(?P<slug>[-\w]+)/$', 'object_detail', entry_info_dict, 'coltrane_entry_detail'),
)

我猜错误是在 entry_info_dict 上。有什么帮助吗？提前致谢。

这是models.py:

import datetime
from django.conf import settings
from django.db import models
from django.contrib.auth.models import User
from tagging.fields import TagField
from markdown import markdown
import tagging

class Category(models.Model):
    title = models.CharField(max_length=250, help_text='Maximum 250 characters.')
    slug = models.SlugField(help_text="Suggested value automatically generated from title. Must be unique.")
    description = models.TextField()

    class Meta:
        ordering = ['title']
        verbose_name_plural = "Categories"

    def __unicode__(self):
        return self.title

    @models.permalink
    def get_absolute_url(self):
        return ('coltrane_category_detail', (), { 'slug': self.slug })

class Entry(models.Model):
    LIVE_STATUS = 1
    DRAFT_STATUS = 2
    HIDDEN_STATUS = 3
    STATUS_CHOICES = (
        (LIVE_STATUS, 'Live'),
        (DRAFT_STATUS, 'Draft'),
        (HIDDEN_STATUS, 'Hidden'),
    )

    # Core fields
    title = models.CharField(max_length=250)
    excerpt = models.TextField(blank=True)
    body = models.TextField()
    pub_date = models.DateTimeField(default=datetime.datetime.now)

    # Metadata
    author = models.ForeignKey(User)
    enable_comments = models.BooleanField(default=True)
    featured = models.BooleanField(default=False)
    slug = models.SlugField(unique_for_date='pub_date')
    status = models.IntegerField(choices=STATUS_CHOICES, default=LIVE_STATUS)

    # Categorization
    categories = models.ManyToManyField(Category)
    tags = TagField()

    # Fields to store generated HTML
    excerpt_html = models.TextField(editable=False, blank=True)
    body_html = models.TextField(editable=False, blank=True)

    class Meta:
        verbose_name_plural = "Entries"
        ordering = ['-pub_date']

    def save(self, force_insert=False, force_update=False):
        self.body_html = markdown(self.body)
        if self.excerpt:
            self.excerpt_html = markdown(self.excerpt)
        super(Entry, self).save(force_insert, force_update)

    def __unicode__(self):
        return self.title

    @models.permalink
    def get_absolute_url(self):
        return ('coltrane_entry_detail', (), { 'year': self.pub_date_strftime("%Y"), 'month': self.pub_date_strftime("%b").lower(), 'day': self.pub_date.strftime("%d"), 'slug': self.slug })

这是主要的 urls.py

from django.conf.urls.defaults import *
from django.contrib import admin
import settings
admin.autodiscover()

from coltrane.models. import Entry

urlpatterns = patterns('',
    # Example:
    # (r'^cms/', include('cms.foo.urls')),

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

    # Uncomment the next line to enable the admin:
    (r'^admin/', include(admin.site.urls)),
    (r'^search/$', 'cms.search.views.search'),
    (r'tiny_mce/(?P<path>.*)$', 'django.views.static.serve', { 'document_root': '/Users/danielcorreia/Sites/tinymce/jscripts/tiny_mce' }),
    (r'^weblog/', include('coltrane.urls')),
    (r'', include('django.contrib.flatpages.urls')),
)

Answer 1

在您的主 urls.py你有:

from coltrane.models. import Entry

将其更改为:

from coltrane.models import Entry

这将解决这个问题。 :D
