我正在通过Practical Django Projects的书工作,我很难过。这本书适用于早期版本的Django。我正在使用v1.3。
问题在视图中,在'search_ 关键字 _keyword__in ...'
from django.contrib.flatpages.models import FlatPage
from django.shortcuts import render_to_response
def search(request):
query = request.GET.get('q', '')
keyword_results = results = []
if query:
keyword_results = FlatPage.objects.filter(searchkeyword__keyword__in=query.split()).distinct()
results = FlatPage.objects.filter(content__icontains=query)
return render_to_response('search/search.html',
{'query' : query,
'keyword_results': keyword_results,
'results' : results })
models.py是
from django.contrib.flatpages.models import FlatPage
from django.db import models
class SearchKeyword(models.Model):
keyword = models.CharField(max_length=50)
page = models.ForeignKey(FlatPage)
def __unicode__(self):
return self.keyword
完整错误是:
Cannot resolve keyword 'searchkeyword' into field. Choices are: content, enable_comments, id, registration_required, sites, template_name, title, url
我认为FlatPages的选项。似乎没有找到外键关系。
任何想法可能是错误的或如何正确地进行查找?感谢。
以下是admin.py,以防它有一些方法:
from django.contrib.flatpages.admin import FlatPageAdmin
from django.contrib import admin
from cms.search.models import SearchKeyword
from django.contrib.flatpages.models import FlatPage
# Define an inline admin descriptor for SearchKeywords model
class SearchKeywordInline(admin.TabularInline):
model = SearchKeyword
# Define a FlatPageAdmin class
class ExtendedFlatPageAdmin(FlatPageAdmin):
inlines = [
SearchKeywordInline,
]
# Re-register FlatPageAdmin
admin.site.unregister(FlatPage)
admin.site.register(FlatPage, ExtendedFlatPageAdmin)

ForeignKey的反向关系将命名为searchkeyword_set
(请参阅https://docs.djangoproject.com/en/dev/topics/db/queries/#backwards-related-objects),因此您的查询集应该有searchkeyword_set__keyword__in
作为参数(或者您可以使用related_name。
如果这不起作用,你应该检查你是否已经完成了manage.py syncdb?

似乎问题是:
from django.contrib.flatpages.models import FlatPage
from django.db import models
模型需要先行,如:
from django.db import models
from django.contrib.flatpages.models import FlatPage
我认为发生的事情是在创建ForeignKey之前创建了FlatPage实例,因此FlatPage无法使用SearchKeyword属性。
