我正在尝试将excel文档导入Django DB.我已将以下代码添加到admin.py和model.py.Django的开发似乎有一个错误.我已经阅读了几个关于如何修复此错误的不同文档.但我对如何完全实现它仍然有点迷失.

在Trace中,它一直说我的excel文档需要一个id字段.id我的excel文档中没有字段,也没有告诉我的模型寻找id字段.

我发现的文档说明我应该get_or_init_instance在这里使用:

你们给予的任何帮助都会很棒.

admin.py

class VinCasesAndCampaignsResource(resources.ModelResource):
    published = fields.Field(column_name='published_date')

    def get_instance(self, instance_loaders, row):
        return False

    class Meta:
        model = VinCasesAndCampaigns
        widgets = {}
        fields = ('VIN','LatestOpenCaseID','LatestClosedCaseID', 
                  'OpenDate', 'CloseDate', 'HasCampaigns',)
        import_id_fields = ['VIN']
        export_order = ('VIN',)
        exclude = ('id')

model.py

class VinCasesAndCampaigns(models.Model):
    VIN = models.CharField(max_length=30)
    LatestOpenCaseID = models.DateField()
    LatestClosedCaseID = models.DateField()
    OpenDate = models.DateField()
    CloseDate = models.DateField()
    HasCampaigns = models.BooleanField(default = False)
    HasOpenCampaigns = models.BooleanField(default = …

我试图将zipcodes缩短为各种文件,但我一直在努力

ValueError:无法从重复轴重新索引

我已经阅读了Stackoverflow上的其他文档,但我还没有弄清楚为什么它的重复轴.

import csv
import pandas as pd
from pandas import DataFrame as df
fp = '/Users/User/Development/zipcodes/file.csv'
file1 = open(fp, 'rb').read()
df = pd.read_csv(fp, sep=',')

df = df[['VIN', 'Reg Name', 'Reg Address', 'Reg City', 'Reg ST', 'ZIP',
         'ZIP', 'Catagory', 'Phone', 'First Name', 'Last Name', 'Reg NFS',
