使用表单i创建xml请求并接收xml响应,如下所示:
<Root>
<Header>
<information>info</information>
</Header>
<Main>
<Product>
<Name>name1</Name>
<Description>description1</Description>
<Price>1</Price>
<Pictures>
<Picture>url_1</Picture>
<Picture>url_2</Picture>
</Pictures>
</Product>
</Main>
</Root>
然后使用此函数将xml数据转换为字典:
^{pr2}$并将其存储到数据库:
from pprint import pprint
d = etree_to_dict(e)
pprint(d)
d = etree_to_dict(e)
product = d['Root']['Main']['Product']
r = Product.objects.create()
r.name = product['Name']
r.description = product['Description']
r.price = product['Price']
r.save()
一切都很顺利。但当我尝试将图片保存到数据库时:
product_pictures=d['Root']['Main']['Pictures']
for m in product_pictures:
p = ProductPictures(
picture = m['Picture']
)
p.product = r
p.save()
r.productpictures_set.all()
我得到了TypeError
string indices must be integers, not str
在字符串picture = m['Picture']
上。
为什么会这样?我做错了什么。谢谢你的回答。在
这是我的模型:
class Product(models.Model):
name = models.CharField(max_length=200, blank=True, null=True)
description = models.TextField(max_length=2000, blank=True, null=True)
price = models.CharField(max_length=10, blank=True, null=True)
class ProductPictures(models.Model):
product = models.ForeignKey(Product, null=True)
picture = models.CharField(max_length=200, blank=True, null=True)
升级版:
以下是来自Local vars
的数据:
product_pictures
{'Picture': [{'#text': 'http://images.static.goglobal.travel/images/hotels/67862/2010113161131438.jpg',
'@Description': ''},
{'#text': 'http://images.static.goglobal.travel/images/hotels/67862/2010113161132187.jpg',
'@Description': ''},
{'#text': 'http://images.static.goglobal.travel/images/hotels/67862/2010113161132406.jpg',
'@Description': ''}]}
m
'Picture'
d
{'Root': {'Header': {'Information': '1521337'},
'Main': {'Name': 'name1',
'Price': '1',
'Description': 'description',
'Pictures': {'Picture': [{'#text': 'http://images.static.goglobal.travel/images/hotels/67862/2010113161131438.jpg',
'@Description': ''},
{'#text': 'http://images.static.goglobal.travel/images/hotels/67862/2010113161132187.jpg',
'@Description': ''},
{'#text': 'http://images.static.goglobal.travel/images/hotels/67862/2010113161132406.jpg',
'@Description': ''}]},
'RoomFacilities': None}}}
productpictures是一个对象/字典,只有一个图片键,所以遍历它没有意义。您可以在
Picture
上迭代。在虽然我怀疑树dict的创建中存在一个问题,可能值得进一步调试。在
