我要通过你在那里建立一个小型社交书签应用书中Django的1.0网站开发。我在那里章创建表单添加书签5,虽然我已经按照指示,并一直在努力对这个错误天。我得到的错误:
I'm going through the book Django 1.0 Website Development where you build a small social bookmarking application. I'm at chapter 5 where you create a form to add bookmarks and although I've followed the instructions and have been struggling on this error for days. I get the error:
AttributeError at /save/
'set' object has no attribute 'get'
该错误被抛出在模板上的第6行{{form.as_p}}
The error is being thrown on line 6 of the template {{ form.as_p }}
在views.py code是:
The views.py code is:
def bookmark_save_page(request):
if request.method == 'POST':
form = BookmarkSaveForm(request)
if form.is_valid():
# create or get link.
link, dummy = Link.objects.get_or_create(
url=form.cleaned_data['url']
)
# create or get bookmark.
bookmark, created = Bookmark.objects.get_or_create(
user=request.user,
link=link
)
# if bookmark is being updated, clear the old tag list
if not created:
bookmark.tag_set.clear()
# create new tag list
tag_names = form.cleaned_data['tags'].split()
for tag_name in tag_names:
tag, dummy = Tag.objects.get_or_create(name=tag_name)
bookmark.tag_set.add()
# save bookmark to database
bookmark.save()
return HttpResponseRedirect(
'/user/%s/' % request.user.username
)
else:
form = BookmarkSaveForm()
variables = RequestContext(request, {
'form' : form
})
return render_to_response('bookmark_save.html', variables)
和模板code是:
{% extends "base.html" %}
{% block title %}Save Bookmark{% endblock %}
{% block head %}Save Bookmark{% endblock %}
{% block content %}
<form method="post" action=".">{% csrf_token %}
**{{ form.as_p }}**
<input type="submit" value="save" />
</form>
{% endblock %}
任何帮助将是非常美联社preciated因为我被困在书中这一点,似乎无法找到答案。谢谢!
Any help would be much appreciated as I'm stuck at this point in the book and can't seem to find an answer. Thanks!
推荐答案
这是一个错误的吗?
for tag_name in tag_names:
tag, dummy = Tag.objects.get_or_create(name=tag_name)
bookmark.tag_set.add() # not adding the tag?
难道不应该是: bookmark.tag_set.add(标签)
?在。新增()
实际上并没有造成错误,但我知道您不添加您的标记。
Shouldn't it be: bookmark.tag_set.add(tag)
? The .add()
doesn't actually cause an error, but I know you aren't adding your tag.
在没有看到追踪,我猜。
Without seeing the traceback, I'm guessing.
我的另一个猜测是,你可能会使用的RequestContext错了?
My other guess is that you might be using the RequestContext wrong?
return render_to_response('bookmark_save.html',
{'form': form},
context_instance=RequestContext(request))
我相信你现在正在使用它的方式是为使用的Htt presponse()的非快捷方式
I believe the way you are using it now is meant for the non-shortcut approach of using an HttpResponse()
