我有以下模型,因爲其意圖是具有每個項目的動態屬性。將選項顯示爲同一模型表單的另一個屬性django
class Attribute(models.Model):
label = models.CharField(max_length = 255)
class Value(models.Model):
attribute = models.ForeignKey(Attribute)
value = models.CharField(max_length = 255)
class Item(models.Model):
user = models.ForeignKey(User, editable = False)
title = models.CharField(max_length = 150, blank = True)
price = models.DecimalField(max_digits = 8, decimal_places = 2, null = True)
categories = models.ManyToManyField(Category)
class Datasheet(models.Model):
item = models.ForeignKey(Item, editable = False)
attribute = models.ForeignKey(Attribute)
currentValue = models.ForeignKey(Value)
當我保存沒有問題的,但是當我要編輯的數據表形式的數值顯示我的何種屬性的 所有可能的值:
Datasheet
Item: Mouse
Attribute: Color
Values: Red, Orange, Yellow, Blue, Apple, Honda, Yamaha
但我只需要看到的屬性值爲了那個原因。
Datasheet
Item: Mouse
Attribute: Color
Values: Red, Orange, Yellow, Blue
在視圖:
datasheetFormSet = inlineformset_factory(Item, Datasheet, form = DatasheetForm, extra = 0)
formsetDatasheet = datasheetFormSet(instance = item)
任何人有這種問題的經驗?
