Adding foreignKey widget to django-import-export

Question

I\'m trying to import data to one of my models, but it\'s failing because I\'m trying to upload the foreignKey Id, not the iterated number that import-export creates.

Answer 1

There is ForeignKeyWidget in the documentation. You can use it here. There are also IntegerWidget and DecimalWidget.

from import_export.admin import ImportExportModelAdmin

class SolResource(resources.ModelResource):
    school_id = fields.Field(
        column_name='school_id',
        attribute='school_id',
        widget=ForeignKeyWidget(School, 'name'))

    class Meta:
        model = Sol

class SolAdmin(ImportExportModelAdmin):
    list_display = ('name', 'school_id')
    resources_class = SolResource

admin.site.register(Sol, SolAdmin)

This is a working example. Hope it will help.

Answer 2

Use the widget- works great.

school_id = fields.Field(column_name='school_id', attribute='Sol', widget=widgets.ForeignKeyWidget(Sol, 'school_id'))

Answer 3

i think it will help:

class SolResource(resources.ModelResource):
    school_id = fields.Field()

    class Meta:
        # ...

    def dehydrate_school_id(self, sol):
        return sol.school_id.school_id # You can get all fields of related model. This is example.
