'str'對象沒有屬性'get'（Django）

Question

Ahoy Mateys！

了一個simpel形式在這裏一個簡單的模型：

class Hardware(models.Model): 
type_name = models.CharField(max_length=60) 

def __unicode__(self): 
    return self.type_name 



class HardwareForm(ModelForm): 
    class Meta: 
     model = Hardware 
     fields = ['type_name'] 

，這是用我的簡單看法功能：

def createHardware(request): 
if request.method == 'POST': 
    form = HardwareForm('request.POST') 
    if form.is_valid(): 
     new_hardware = form.save() 


     return render_to_response('administration/overview.html') 
else: 
    form = HardwareForm() 

    return render_to_response('administration/create_hardware.html', { 
        'form': form, }, context_instance = RequestContext(request)) 

這是回溯：

Environment:

    207.   return data.get(name, None) 

Exception Type: AttributeError at /ticket/createHardware/ 
Exception Value: 'str' object has no attribute 'get' 

所以我得到了更多的數據在其中的幾個表單，並沒有問題將一個空的表單傳遞給html頁面，填充它ut並將它們發回到該函數以獲取表單中的數據。運行is_valid（）並將數據傳遞給模型的新實例（向其添加更多數據）

爲什麼我在這裏得到這個錯誤？

Answer 1

您需要將字典傳遞給您的HardwareForm，而不是字符串。

改變你views.py

form = HardwareForm('request.POST') 

到：

form = HardwareForm(request.POST)
