Question

When I try using in Django the "filter" Method:

dumpData.objects.filter(bid = True)

我有以下例外:

进口错误: 没有名为“贸易”的模块

贸易是我的达詹戈应用治理环境。 under

INSTALLED_APPS = (    
(...),
 Trades )

DumpData的定义是:

class DumpData(models.Model):
    orderId = models.BigIntegerField()
    typeId = models.BigIntegerField()
    price = models.DecimalField(decimal_places=2,max_digits=20)
    bid = models.BooleanField()
    issued = models.DateField()
    dateDumped = models.DateTimeField()

我只想

dumbData.objects.all()

所有这些工作都很重,因此可能不是一个服务器/银问题。 (因此我可以无一例外地拯救日期)。

Ok i solved my Problem. The reason because it didnt worked was in the Project Strukture, i had:

src
    PackageNr1
       Main.py  <-- File where Django was called.
    PackageNr2  <-- Package for the Django Files
       	rades   <-- Django App
          models.py , 
          views ...usw 
       settings.py  <-- Django Settings File
       manage.py

itch这种 Str子可以称作“ave”或“bject(bject)”等物品,并做罚款。但是,用多数称呼的是它所干的。因此,我把我的Django一揽子计划移入了主波克奇,现在正在运行。新的“强硬”就是这样:

 src
    PackageNr1
        	rades    <-- The django app
            models.py
            views ....
        Main.py
        settings.py <--Django Files
        manage.py

这对我来说是一件事。

Answer 2

I didn t found any documentation about it, but I would suggest to use lowercase names for apps. Also, try :

dumpData.objects.filter(bid = True).all()
