小编sup*_*rio的帖子

灵感来自这一博客帖子,我试图让通过保存搜索参数为会话,以便查询可以通过分页保存处理配置文件搜索一个观点.

以下是观点:

def profile_search(request):
    args = {}
    qs=[]
    if not request.method == 'POST':        
        if 'search-profiles-post' in request.session: 
            request.POST = request.session['search-profiles-post'] 
            request.method = 'POST' 


    if request.method == "POST":
        form = AdvancedSearchForm(request.POST)
        request.session['search-profiles-post'] = request.POST


        if form.is_valid():
            cd = form.cleaned_data

            s_country=cd['country']
            s_province=cd['province']
            s_city = cd['city']

        if s_city: qs.append( Q(city__in=s_city))
            if s_country: qs.append(Q(country__icontains = s_country))
            if s_province: qs.append( Q(province__icontains=s_province))    



            f = None
            for q in qs:
                if f is None: 
                    f=q                                  
                else: f &=q
            print f

            if f is not None: …

我有两个应用程序news,article它们都具有完全相同的型号名称Comment:

class Comment(models.Model):
    author = models.ForeignKey(User)
    created = models.DateTimeField(auto_now_add=True)
    title = models.CharField(max_length=100, default='', blank=True)
    body = models.TextField()
    post = models.ForeignKey(Photo)
    published = models.BooleanField(default=True)

现在,在一个视图中我想删除两个应用程序中的某些注释:

Comment.objects.filter(author=someauthor).delete()

如何在不更改模型名称的情况下实现这一目标？

我有这个视图,它添加了对主题的回复:

@login_required
def post_reply(request, topic_id):
    tform = PostForm()
    topic = Topic.objects.get(pk=topic_id)
    args = {}
    if request.method == 'POST':
        post = PostForm(request.POST)

        if post.is_valid():

            p = post.save(commit = False)
            p.topic = topic
            p.title = post.cleaned_data['title']
            p.body = post.cleaned_data['body']
            p.creator = request.user
            p.user_ip = request.META['REMOTE_ADDR']

            p.save()

            tid = int(topic_id)


        args['topic_id'] = tid
        args['topic'] = topic
        args['posts'] = Post.objects.filter(topic_id= topic_id).order_by('created')
        return render_to_response("myforum/topic.html",args)            

    else:
        args.update(csrf(request))
        args['form'] = tform
        args['topic'] = topic
        return render_to_response('myforum/reply.html', args, 
                                  context_instance=RequestContext(request))

问题是当用户在发布回复后引用页面时,她的回复正在被复制.怎么避免这个？

更新:这是相关的模板:

{% extends "base.html"%}
{% load static %} …

在我的 Ubuntu 18.04 机器上，我正在按照教程启动一个 svelte 项目，但无法使用 degit 进行身份验证：

$ npx degit sveltesj/template ninjapolls
Username for 'https://github.com': myname
Password for 'https://myname@github.com': mypw
! could not fetch remote https://github.com/sveltesj/template
! could not find commit hash for master

我很确定我的凭据是正确的，因为我刚刚在浏览器上使用它登录到 github。那么这里可能出了什么问题以及如何修复它？

我做了一个包含如下字段的表单：

sex = forms.ChoiceField(choices= SEX)

哪里：

SEX = (
    ('F','Female'),
    ('M','Male'),
    ('U','Unsure'),
    )

现在我想知道如何最好地定义性别模型？我知道可以这样做：

class UserProfile(models.Model):
    user = models.ForeignKey('User')
    sex = models.CharField(max_length=10)

但是，没有比CharField更好的选择了吗？
