This has been asked several times- but none of the solutions worked for me.
The code below works (in that there are no errors) but it does not see anything to import new data to the foreign key class. It will only import data if it already exists in the foreign key.
Does that make sense?
Models.py (snippet)
...
class Store(models.Model):
store_name = models.CharField(max_length=30)
def __unicode__(self):
return self.store_name
#etc
class Product(models.Model):
Store = models.ForeignKey(Store)
Category = models.ForeignKey(Category)
first_name = models.CharField(max_length=30)
second_name = models.CharField(max_length=30)
...
Admin.py
admin.site.register(Category)
admin.site.register(Store)
class ProductResource(resources.ModelResource):
store_name = fields.Field(column_name='store_name', attribute='Store',
widget=ForeignKeyWidget(Store, 'store_name'))
def __unicode__(self):
return self.store_name.name
class Meta:
model = Product
fields = ('id', 'first_name', 'second_name','store_name')
export_order = ('id', 'second_name', 'first_name')
skip_unchanged = False
report_skipped = False
widgets = {
'published': {'format': '%d.%m.%Y'},
}
class ProductAdmin(ImportExportModelAdmin):
resource_class = ProductResource
list_display = ('first_name', 'second_name')
admin.site.register(Product, ProductAdmin)
Try
store_name = fields.Field(column_name='store_name', attribute='Store',
widget=ForeignKeyWidget(Store, 'store_name'))
I suggest you name model field uncapitalized
It's hard to understand what you are really asking.
If what you are saying is that "Want to create foreign key objects and fill the foreign object's attribute with the excel data"
I think you need to do first create the foreign object and relate it to the other model which means, you would need to override or define a function in your ModelResource class and have it called from your admin.
They have a widget for this- http://django-import-export.readthedocs.org/en/latest/api_widgets.html. I do not understand how to use it tho.
