经过如此多的谷歌搜索后,我没有找到任何相关的解决方案来获取视图中的关联模型数据。
事情是我通过Ajax向服务器请求并且想要获取文件夹和文件夹创建者名称(来自用户模型)。但它并没有让我成为创作者的第一个名字。这是代码
models.py
class UserFolder(models.Model):
creator = models.ForeignKey(User)
name = models.CharField(blank=False, max_length=150)
is_shared = models.BooleanField(default=False)
created_date = models.DateTimeField(auto_now_add=True)
modified_date = models.DateTimeField(auto_now=True)
def __str__(self):
return self.name
views.py
def pagination(obj, request):
max = request.GET.get('max') if 'max' in request.GET else 1
paginator = Paginator(obj, max) # Show 25 contacts per page
page = request.GET.get('page')
try:
return paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
return paginator.page(1)
except EmptyPage:
return ""
def folder_list(request): #called via ajax
folders = UserFolder.objects.filter(creator=request.user.id).order_by('-modified_date')
folders = pagination(folders, request) #for pagination
folders = json.dumps({}) if not folders else serializers.serialize("json", folders)
return HttpResponse(folders)
我也尝试了 .select_related('creator'),但它确实没有用。
在js中,我正在获取这样的数据:
$.each(data, function(i, v) {
var t = fldrTpl, id = v.pk;
v = v.fields
t = t.replace(/\{(ID)\}/g, id);
t = t.replace(/\{(NAME)\}/g, v.name);
t = t.replace(/\{(C_SIZE)\}/g, (v.current_size == null?0:v.current_size));
t = t.replace(/\{(C_ID)\}/g, v.creator.first_name);
t = t.replace(/\{(C_DATE)\}/g, v.created_date);
$(".my-folder-table").append(t);
});
v.creator.first_name 始终返回undefined。
任何帮助都会非常感激。

您始终可以在客户端创建要使用的数据字典:
def folder_list(request): #called via ajax
folders_obj = UserFolder.objects.filter(creator=request.user).select_related('creator').order_by('-modified_date').all()
folders_dict = []
for folder in folders_obj:
d = {}
for k, v in folder.__dict__.items():
d[k] = str(v)
d["creator__first_name"] = folder.creator.first_name
folders_dict.append(d)
folders = pagination(folders_dict, request) #for pagination
folders = json.dumps({}) if not folders else serializers.serialize("json", folders)
return HttpResponse(folders)
在你的js:
t = t.replace(/\{(C_ID)\}/g, v.creator__first_name);
