【问题描述】:
来自models.py
class Indicator(models.Model):
name = models.CharField(max_length=50)
youtube = models.CharField(max_length=LONG_BLOG_POST_CHAR_LEN)
description = models.CharField(max_length=LONG_BLOG_POST_CHAR_LEN)
recommendation = models.CharField(max_length=LONG_BLOG_POST_CHAR_LEN)
isPublic = models.BooleanField(default=False)
methods_path = models.CharField(max_length=100,default=None)
meta_description = models.CharField(max_length=150,default='')
image_path = models.CharField(max_length=100,blank=True)
def __str__(self):
return self.name
class IndicatorParameterInt(models.Model):
name = models.CharField(max_length=50)
value = models.IntegerField(default=1)
indicator_int_parameter = models.ForeignKey(Indicator, on_delete=models.CASCADE)
hidden = models.BooleanField(default=False)
class IndicatorParameterFloat(models.Model):
name = models.CharField(max_length=50)
setting = models.FloatField(default=1)
indicator_float_parameter = models.ForeignKey(Indicator, on_delete=models.CASCADE)
hidden = models.BooleanField(default=False)
class Comparison(models.Model):
name = models.CharField(max_length=100)
来自 admin.py
from django.contrib import admin
from .models import *
# Register your models here.
admin.site.register( MarketData )
admin.site.register( Indicator )
admin.site.register( UserProfile )
class IndicatorParameterIntInline(admin.TabularInline):
model = IndicatorParameterInt
fk_name = "indicator_int_parameter"
class IndicatorParameterFloatInline(admin.TabularInline):
model = IndicatorParameterFloat
fk_name = "indicator_float_parameter"
class ComparisonInline(admin.TabularInline):
model = Comparison
fk_name = "Comparison"
class IndicatorInline(admin.ModelAdmin):
inlines = [
IndicatorParameterIntInline,
IndicatorParameterFloatInline,
ComparisonInline,
]
admin.site.unregister( Indicator )
admin.site.register( IndicatorInline )
错误 TypeError: 'MediaDefiningClass' object is not iterable 出现在 admin 的最后一行:admin.site.register( IndicatorInline )。如果我尝试先注册 IndicatorInline 或任何外键类都没关系。
我引用了this post,它鼓励使用 fk_name 属性。无论我是否使用 fk_name,都会发生错误。
