There are 2 models CPU and GalleryCPU (see models.py below), they are interconnected by a one-to-many relationship. I did this in order to make it possible to add several pictures. That is, I connected 2 models with one-to-many communication and added inline editing (see screenshot below).

models.py

class CPU(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE, verbose_name='Категория') slug = models.SlugField() manufacturer = models.CharField(max_length=5, choices=CHOISE_MANUFACTURER, verbose_name='Производитель') series = models.ForeignKey(SeriesCPU, on_delete=models.CASCADE, verbose_name='Серия') socket = models.ForeignKey(Socket, on_delete=models.CASCADE, verbose_name='Сокет') model = models.CharField(max_length=15, verbose_name='Модель') core = models.ForeignKey(Core, on_delete=models.CASCADE, verbose_name='Ядро') count_core = models.SmallIntegerField(verbose_name='Количество ядер') count_stream = models.SmallIntegerField(verbose_name='Количество потоков') normal_frequency = models.SmallIntegerField(verbose_name='Тактовая частота') turbo_frequency = models.SmallIntegerField(verbose_name='Частота в режиме Turbo') unlocked_multiplier = models.BooleanField(default=False, verbose_name='Разблокированный множитель') cash_size_L1 = models.SmallIntegerField(verbose_name='Объем кэша L1') cash_size_L2 = models.SmallIntegerField(verbose_name='Объем кэша L2') cash_size_L3 = models.SmallIntegerField(blank=True, null=True, verbose_name='Объем кэша L3') integrated_graphics_core = models.CharField(max_length=25, default='нет', verbose_name='Интегрированное графическое ядро') frequency_graphics_core = models.SmallIntegerField(blank=True, null=True, verbose_name='Частота') technologic_process = models.SmallIntegerField(verbose_name='Технологический процесс') heat_dissipation = models.SmallIntegerField(verbose_name='Тепловыделение') technology = models.ManyToManyField(TechnologyCPU, verbose_name='Технологии') CHOISE_TYPE_DELIVERY = ( ('box', 'BOX'), ('oem', 'OEM'), ) type_delievery = models.CharField(max_length=3, choices=CHOISE_TYPE_DELIVERY, verbose_name='Тип поставки') guarantee = models.SmallIntegerField(verbose_name='Гарантия') count = models.SmallIntegerField(verbose_name='Количество') price = models.BigIntegerField(verbose_name='Цена') class Meta: verbose_name_plural = "Процессоры" verbose_name = 'Процессор' unique_together = ('series', 'model', 'type_delievery') class GalleryCPU(models.Model): image = models.ImageField(upload_to='img\CPU', verbose_name='Изображение процессора') cpu = models.ForeignKey(CPU, on_delete=models.CASCADE, related_name='images', verbose_name='Процессор') class Meta: verbose_name_plural = "Изображения процессоров" verbose_name = "Изображение процессора"

Inline editing I would like that when adding images for a specific CPU, a folder with the name of this CPU is created and all the images are loaded into this folder. For example, I add a CPU named Ryzen 5 1600, and when I add pictures for this CPU, I create a folder named Ryzen 5 1600 and all the pictures are loaded into this folder.

There is an idea to do the following in the CPU model, there is a slug field, based on this, you can implement the following method:

 def image_folder(instance, filename): filename = instance.slug + '.' + filename.split('.')[1] return "{0}/{1}".format(instance.slug, filename)

The method above automatically creates a folder named slug and uploads a picture there. However, it is suitable only when both the Slug type field and the ImageField type are in the same model, that is, the CPU model. But I repeat once again, they are in my different models, and this was done in order to be able to add several pictures. The question is how to automatically create a folder for CPU images with the name of this CPU?

    However, it is suitable only when both the Slug type field and the ImageField type are in the same model.

    No, it is not. Nothing prevents you from accessing a related model with a foreign key:

     return "{0}/{1}".format(instance.cpu.slug, filename)
    • changed ka method you said. In the GalleryCPU model, changed the upload_to image = models.ImageField(upload_to=image_folder, verbose_name='Изображение процессора') . Now, when adding pictures, the error 'GalleryCPU' object has no attribute 'slug' appears - Elusive Joe
    • one
      @ ElusiveJo and have you changed the line above? - Sergey Gornostaev
    • @Sergey_Gornostaev changed the string in the method with the return that you changed. In the GalleryCPU model, changed upload_to, to upload_to=image_folder - Elusive Joe
    • Thanks, you had to change filename = instance.cpu.slug + '.' + filename.split('.')[1] filename = instance.cpu.slug + '.' + filename.split('.')[1] . Now everything works - Elusive Joe
