卡住了「實用的Django項目」

Question

本教程有另一個錯誤。我應該放棄並轉移到另一個？ ... 反正..這裏有雲：

這裏的網址：

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'), 
) 

我猜的錯誤是entry_info_dict。任何幫助？提前致謝。

這裏的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 }) 

這裏的主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

在你的主urls.py您有：

from coltrane.models. import Entry 

修改成：

from coltrane.models import Entry 

這將解決這個問題。 ：D

Answer 2

你的模型有一個 「活」 的經理嗎？
