My admin side will be used by non-sys-admin users, so I would like this to be as clear as possible. I do not understand how to set up a preview before confirming the import.
To add objects with a foreign key reference, I'm just looking for an identifier that matches the function before_importand will replace it, as it explains here .
If you change the data set in the before_import function, it does not apply to the preview, the preview only displays the object of my model class, nothing more ...
How can I display the family name (column Famille) in my example?
My model:
class TGenres(models.Model):
id_genre = models.AutoField(primary_key=True, unique=True)
nom_genre = models.CharField(max_length=1024,verbose_name='nom de genre')
id_fam = models.ForeignKey(TFamilles, null=True, db_column='id_fam', blank=True, verbose_name='Famille')
