I have a Product model, an Image Model and a Category Model.
A Product can have multiple Images(Foreign Key) and a Product can be in
multiple Categories a Category can contain multiple Products.
A Category can have multiple subcategories(key to itself).
class Category(MetaData):
parent = models.ForeignKey('self', blank=True, null=True, verbose_name='parent
category', on_delete=models.CASCADE)
class ProductMetaData):
categories = models.ManyToManyField(Category)
class ProductImage(models.Model):
product = models.ForeignKey(Product, related_name='image', on_delete=
models.CASCADE)
In Product Django Admin:
class ProductDocumentInline(admin.TabularInline):
model = ProductDocument class ProductAdmin(MetaData):
inlines = [ProductImageInline]
fieldsets = (
('Product Data', {
'fields': ('name', 'short_description', 'description')
}),
('SEO', {
'classes': ('collapse',),
'fields': ('meta_title', 'meta_description', 'slug', 'canonical')
}),
('MetaData', {
'classes': ('collapse',),
'fields': (('created_at', 'created_by'), ('updated_at', 'updated_by'))
}),
)
readonly_fields = ('created_at', 'updated_at', 'created_by', 'updated_by')
list_display = ('name', 'updated_at')
ordering = ('-updated_at',)
search_fields = ('name',)
admin.site.register(Product, ProductAdmin)
admin.site.register(ProductImage)
Issues:
1.
If I don't customize fieldsets (grouped, ordered) the Categories appear
like default in the middle of the form. If there are customized as in my
example they don't appear.
2.
If they don't appear Products without Categories can be created and I
don't want that. I want a product to have at least one category.
3.
Now the inline Images appear below all Product fields.
I want the Categories to appear first, then normal fields for
Product(grouped,ordered), Images inline and at the end the SEO and metadata
fields. How can this be done ?
