              'item_sub_category','item_est_price','item_wst_price',)

tried many forums & third party packages too but their isn't any way out from this problem. Also GET is working totally fine.

Thanks for your time

Answer 1

From Django Docs -

If you intend to allow users to upload files, you must ensure that the environment used to run Django is configured to work with non-ASCII file names. If your environment isn’t configured correctly, you’ll encounter UnicodeEncodeError exceptions when saving files with file names that contain non-ASCII characters.

Thus adding this method to the model solved my problem :

class Product(models.Model):
item_category_choices = (
    ('Make Up','Make Up'),
    ('Skin Care','Skin Care'),
    ('Fragrance','Fragrance'),
    ('Personal Care','Personal Care'),
    ('Hair Care','Hair Care'),
    )
item_name = models.CharField(max_length=50,verbose_name='Product Name')
item_image = models.ImageField(verbose_name='Product Image')
item_thumb = models.ImageField(verbose_name='Product Thumb')
item_description = models.TextField(verbose_name='Product Descriptions')
item_mass = models.CharField(max_length=10,verbose_name='Product Weight')
item_category = models.CharField(max_length=20, choices = item_category_choices,verbose_name='Product Category')
item_sub_category = models.CharField(max_length=20,verbose_name='Product Sub Category')
item_est_price = models.DecimalField(max_digits=12,decimal_places=2,verbose_name='East Product Price')
item_wst_price = models.DecimalField(max_digits=12,decimal_places=2,verbose_name='West Product Price')
def __unicode__(self):
            return (self.item_name)
def image_img(self):
    if self.item_image:
        return u'<img src="%s" width="50" height="50" />' % self.item_image.url
    else:
        return '(Sin imagen)'
image_img.short_description = 'Thumb'
image_img.allow_tags = True
