我試圖使用自定義管理器方法創建測試裝置,因爲我的應用程序使用dbtables的子集和更少的記錄。所以我放棄了使用initial_data的想法。在經理中,我正在做這樣的事情。在Managers.py:使用自定義管理器方法,json轉儲和避免類型錯誤的方式創建裝置:xxx不是json可序列化
sitedict = Site.objects.filter(pk=1234).values()[0]
custdict = Customer.objects.filter(custid=123456).values()[0]
customer = {"pk":123456,"model":"myapp.customer","fields":custdict}
site = {"pk":0001,"model":"myapp.site","fields":sitedict}
csvfile = open('shoppingcart/bsofttestdata.csv','wb')
csv_writer = csv.writer(csvfile)
csv_writer.writerow([customer,site])
然後我做了修改我的csv文件來代替單引號雙,等於是我沒有保存該文件作爲json.Sorry如果太愚蠢方式,但是這是我第一次「米創建TESTDATA,我很想學習文件的更好way.Sample數據是這樣的:MYAPP /燈具/ testdata.json
[{"pk": 123456, "model": "myapp.customer", "fields": {"city": "abc", "maritalstatus": None, "zipcode": "12345", "lname": "fdfdf", "state": "AZ", "agentid": 1111, "fname": "sdadsad", "email": "[email protected]", "phone": "0000000000", "custid":123456,"datecreate": datetime.datetime(2011, 3, 29, 11, 40, 18, 157612)}},{"pk":0001, "model": "myapp.site", "fields": {"url": "http://google.com", "websitecode": "", "notify": True, "fee": 210.0, "id":0001}}]
我用它來運行我的測試,但我得到了以下錯誤:
