小编Bad*_*ach的帖子

这是我的第一个问题,所以我会感激耐心.

我从CharField将一些属性更改为IntegerField.下面列出的是代码:

rating_choices = (
    (1,"1"),
    (2,"2"),
    (3,"3"),
    (4,"4"),
    (5,"5"),
)

class Rating(models.Model):
    article = models.ForeignKey(Article,null=True)
    organization = models.IntegerField(choices=rating_choices, default=1)
    support = models.IntegerField(choices=rating_choices, default=1)
    readability = models.IntegerField(choices=rating_choices, default=1)
    tags = models.IntegerField(choices=rating_choices, default=1)
    comments = models.TextField()
    def get_overall_rating(self):
        return fsum(self.organization + self.support + self.support + self.readability + self.tags)/5.0
    overall_rating = property(get_overall_rating)
admin.site.register(Rating)

我做了一个南迁移到Postgres迁移,这是我得到的错误:

Error in migration: collect_data:0010_auto__chg_field_rating_tags__chg_field_rating_support__chg_field_ratin
Traceback (most recent call last):

    utility.execute()
  File "/Users/narensathiya/Documents/Documents/Jellow/Jellow/jellowenv/lib/python2.7/site-packages/django/core/management/__init__.py", line 382, in …

我在'tags'字段上实现了一个提升; 但是它没有以适当的方式对我的结果进行排名.

我的search_indexes.py:

class ParagraphIndex(indexes.SearchIndex, indexes.Indexable):
    text= indexes.CharField(document=True, use_template=True, boost=1.0)
    tags= indexes.MultiValueField(boost=2.5)
    def prepare_tags(self,object):
        return [tag.tag for tag in object.tags.all()]

我的常规搜索适用于正确的字段.我已经多次运行update_index并仍然得到相同的答案.任何帮助都感激不尽.如果需要更多信息,请告诉我!

我对django有点新鲜.我试图在上传时选择将文件发送到另一台服务器,但form.is_valid()总是返回false会让我输入if

views.py-

def sent(request):
    if request.method == 'POST':
        form = SendFileForm(request.POST, request.FILES)
        print "form is made"
        print form.errors
        if form.is_valid():
            print "form is valid"
            new_song = Song(songfile= request.FILES['songfile'])
            new_song.save()
            print "new song is made and saved"
            l = List()
            #cd = form.cleaned_data                                                                                                                   
            #SENDS THE FILE TO SERVER GIVEN PATH
            l.all_files(new_song.songfile.path)
            return HttpResponseRedirect(reverse('get_files.views.sent'))
        else:
            print "form is not valid"
    else:
        form = SendFileForm()

    songs = Song.objects.all()
    return render_to_response('sent.html', {'songs': songs,'form': form}, context_instance=RequestContext(request))

sent.html 模板-

{% if form.errors …

所以例如 -

//Functions

var validationCheck = function(req, res, next){
  if(req.session.userId && req.session.token)
      next('validationCatch') //Is this possible to skip middleware if not needed?
  else
      next()
}

var getUserId = function(req, res, next){
  req.session.userId = DB.getUserId
  next()
}

var getToken = function(req, res, next){
  req.session.token = DB.getToken
  next()
}

//a catcher function to direct to next function depending on route
var validationCatch = function(req, res, next){
  next()
}

//Routes

app.get(api + '/feature1', validationCheck, getUserId, getToken, validationCatch, feature1)
app.get(api + '/feature2', validationCheck, getUserId, …
