I am trying to import excel documents into a Django DB. I have added the following code to admin.py and model.py. There seems to be an error in the development of Django. I have read through several different documentations about how to fix this error. But I am still a little lost on how to implement it exactly.

In the Trace it keeps saying that my excel document needs an id field. There is no id field in my excel docs nor did I tell my model to look for an id field.

The documentation that I have found states that I should use get_or_init_instance here:

https://django-import-export.readthedocs.org/en/latest/import_workflow.html

Any help that you guys could give would be great.

admin.py

class VinCasesAndCampaignsResource(resources.ModelResource):published = fields.Field(column_name='published_date')def get_instance(self, instance_loaders, row):return Falseclass Meta:model = VinCasesAndCampaignswidgets = {}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 = False)HasCases = models.BooleanField(default = False)HasEstimates = models.BooleanField(default = False)HasDwell = models.BooleanField(default = False)HasClaims = models.BooleanField(default = False)exclude = ('id',)

Trace:

You can solve this problem by using the following steps:

Step 1 first goto C:/Users/am.sa18/Desktop/myenv/Lib/site-packages/import_export/resources.py

Step 2 open resources.py in the editor.

Step 3 do change in line no 84, its looks like this

Step 4 import_id_fields = ['id'] Where 'id' by-default set by import_export package, you can change 'id' by your primary key of the model. After adding primary key : import_id_fields = ['primary_key']

Step 5 Save resources.py file and run the server.
