AttributeError的：對象類型「爲MyModel」有沒有屬性「_meta」

我已經創建的視圖MyView的（CreateView的）和模型和形式，並得到一個錯誤：AttributeError的：對象類型「爲MyModel」有沒有屬性「_meta」

AttributeError: type object 'MyModel' has no attribute '_meta'

這是我的觀點：

class MyView(CreateView): 
    model = MyModel 
    template_name = "myapp/template1.html"

這裏是我的模型：

class MyModel(models.Model): 
    free_day = models.CharField(max_length=255) 
    name = models.CharField(max_length=255, blank=True, null=True) 

    class Meta: 
     verbose_name = _('MyModel') 
     verbose_name_plural = _('MyModels') 

    def __unicode__(self): 
     return self.free_day

我的形式：

class MyInputForm(forms.ModelForm): 

    class Meta: 
     model = MyModel 
     fields = ('user', 'free_day',)

這是我回溯

請顯示* full * traceback。 – 2015-02-06 07:46:03

我加了完整的回溯。 – mark 2015-02-06 07:50:13

試用了你的代碼，它適用於我。你的'urls.py'中有什麼指向這個視圖？ – 2015-02-06 08:55:48

我不明白究竟爲什麼它給這個錯誤（這似乎爲MyModel實際上不是你的模型類 - 你重新定義了它在其他地方？），但有一個明顯的問題：您認爲應該參考您定義的表單，而不是直接的模型。

class MyView(CreateView): 
    form_class = MyInputForm

謝謝丹尼爾:) – mark 2015-02-06 09:14:02

您是否嘗試過具有間的功能，看起來像這樣;

class MyModel(models.Model): 
    free_day = models.CharField(max_length=255) 
    name = models.CharField(max_length=255, blank=True, null=True) 

    def Meta(): 
     verbose_name = _('MyModel') 
     verbose_name_plural = _('MyModels') 

    def __unicode__(self): 
     return self.free_day

這不起作用。 – mark 2015-02-06 08:22:35

取而代之的是以下內容：

def get(request,self):

你可以使用這樣的事情：

def get(self,request):

其他的一切應該是蠻好的！
