यह मेरा पहला प्रश्न है इसलिए मैं धैर्य की सराहना करता हूं।"पूर्णांक टाइप करने के लिए नहीं डाला जा सकता" त्रुटि
मैंने चार फ़ील्ड से इंटीजरफ़िल्ल्ड में कुछ विशेषताओं को बदल दिया। नीचे सूचीबद्ध कोड है:
rating_choices = (
(1,"1"),
(2,"2"),
(3,"3"),
(4,"4"),
(5,"5"),
)
class Rating(models.Model):
article = models.ForeignKey(Article,null=True)
organization = models.IntegerField(choices=rating_choices, default=1)
support = models.IntegerField(choices=rating_choices, default=1)
readability = models.IntegerField(choices=rating_choices, default=1)
tags = models.IntegerField(choices=rating_choices, default=1)
comments = models.TextField()
def get_overall_rating(self):
return fsum(self.organization + self.support + self.support + self.readability + self.tags)/5.0
overall_rating = property(get_overall_rating)
admin.site.register(Rating)
मैं पर Postgres विस्थापित करने के लिए एक दक्षिण प्रवास किया था और इस त्रुटि मैं मिलता है:
Error in migration: collect_data:0010_auto__chg_field_rating_tags__chg_field_rating_support__chg_field_ratin

किसी भी मदद की बहुत सराहना की जाएगी और अग्रिम धन्यवाद !!
आपकी डेटाबेस में 'tags' स्तंभ में किसी भी आइटम को पहले से ही है कि पूर्णांक के रूप में नहीं हैं ? –
हाँ, वहां होना चाहिए। मैंने कुछ मूल्यों को अक्षर के रूप में सहेजा है। क्या मुझे उस कॉलम को हटाना होगा और इसे रीमेक करना होगा? – Badi8beach
