一个字典的下拉Django的价值观 [英] Values of a dict in a dropdown django

问题描述

我的models.py如下：

My models.py is as follows:

class SellerMarketplaces(models.Model):
id = models.IntegerField(db_column='ID',primary_key=True)  # Field name made lowercase.
seller_id = models.ForeignKey('Sellerdetails',db_column='Seller_ID')  # Field name made lowercase.
mk_id = models.ForeignKey('Marketplace',db_column='Mk_ID')  # Field name made lowercase.
username = models.CharField(db_column='Username', max_length=100, blank=True, null=True) 

我有以下的code。在我的意见

I have the following code in my views

def marketplaces(request):  

seller = request.GET.get('seller', '')
allmarketplaces = SellerMarketplaces.objects.filter(seller_id = seller).values('mk_id__marketplace')
print allmarketplaces

，通过它，我发现了以下的输出：

through which I'm getting the following output:

[{'mk_id__marketplace': u'Flipkart'}, {'mk_id__marketplace': u'Snapdeal'}]

我想显示的值，即，Flipkart和Snapdeal在下拉，但我无法访问的值，当我写

I want to display the values i.e., Flipkart and Snapdeal in a dropdown but I'm unable to access the values, when I'm writing

print allmarketplaces.values()

它给了我

 [{'username': u'[e-mail]', u'seller_id_id': 1L, u'mk_id_id': 1L, 'id': 1L}, {'username': u'[e-mail]', u'seller_id_id': 1L, u'mk_id_id': 2L, 'id': 2L}]

我怎么能访问值（Flipkart＆安培; Snapdeal）？

how can i access the values (Flipkart & Snapdeal)?

推荐答案

您正在寻找的 values​​_list ：

You're looking for values_list:

>>> allmarketplaces = SellerMarketplaces.objects.filter(seller_id=seller).values_list('mk_id__marketplace', flat=True)
>>> print allmarketplaces
['Flipkart', 'Snapdeal']
