Django loaddata错误 [英] Django loaddata error
问题描述
我在app目录中创建了一个fixtures文件夹,并把data1.json放在那里。
这是什么文件:
[{firm_url:http://www.graychase.com/kadam,firm_name:Gray& Chase 第一:卡林,最后一个:亚当,学校:恩斯特莫里茨安德特大学格雷夫斯瓦尔德,年度毕业:2004}]
pre>
在命令行中,我cd到应用程序目录和
django-admin.py loaddata data1.json
但是我收到这个错误
从
'C:\Users\A\Documents\Projects\Django\sw2安装json fixture'data1' \wkw2\fixtures'。

文件C:\Python26\lib\site- packages\django\core\serializers\python.py,第76行,Deserializer
模型= _get_model(d [model])
KeyError:'model'
做错了?
编辑:
我修复了json格式: p>
[
{
pk:1,
model:wkw2.Lawyer ,
字段s:{
学校:乔治华盛顿大学法学院,
last:Babas,
firm_url:http://www.graychase。 com / babbas,
year_graduated:2005,
firm_name:Gray& Chase,
first:Amr A
}
}
]
但现在我得到ValidationError:该值必须是一个整数,有没有办法从行号中找出导致错误的原因?只有pk是一个整数。

解决方案看起来你没有正确定义你的夹具。看看 Django文档。您需要定义要加载的模型,然后定义这样的字段
[
{
model:myapp.person,
pk:1,
fields:{
first_name:John,
last_name Lennon
}
},
{
model:myapp.person,
pk:2,
fields :{
first_name:Paul,
last_name:McCartney
}
}
]
I created a "fixtures" folder in the app directory and put data1.json in there.
This is what is in the file:
[{"firm_url": "http://www.graychase.com/kadam", "firm_name": "Gray & Chase", "first": " Karin ", "last": "Adam", "school": "Ernst Moritz Arndt University Greifswald", "year_graduated": " 2004"} ]
In the command line I cd to the app directory and
django-admin.py loaddata data1.json
but I get this error
Installing json fixture 'data1' from 'C:\Users\A\Documents\Projects\Django\sw2\wkw2\fixtures'. Problem installing fixture 'C:\Users\A\Documents\Projects\Django\sw2\wkw2\fixtures\data1.json': Traceback (most recent call last): File "C:\Python26\Lib\site-packages\django\core\management\commands\loaddata.py", line 150, in handle for obj in objects: File "C:\Python26\lib\site-packages\django\core\serializers\json.py", line 41, in Deserializer for obj in PythonDeserializer(simplejson.load(stream)): File "C:\Python26\lib\site-packages\django\core\serializers\python.py", line 76, in Deserializer Model = _get_model(d["model"]) KeyError: 'model'
What am I doing wrong?
Edit:
I fixed the json format:
[ { "pk": 1, "model": "wkw2.Lawyer", "fields": { "school": "The George Washington University Law School", "last": "Babas", "firm_url": "http://www.graychase.com/babbas", "year_graduated": "2005", "firm_name": "Gray & Chase", "first": "Amr A" } } ]
But now I get ValidationError: This value must be an integer. Is there a way to find out from the line numbers what causes the error? Only "pk" is an integer.

解决方案it looks like you are not defining your fixtures properly. Take a look at the Django Documentation. You need to define the model that you are loading, then define the fields like this
[ { "model": "myapp.person", "pk": 1, "fields": { "first_name": "John", "last_name": "Lennon" } }, { "model": "myapp.person", "pk": 2, "fields": { "first_name": "Paul", "last_name": "McCartney" } } ]
