Question

models.py
class Product(models.Model):
title = models.CharField(max_length=200)
description = models.TextField()
price = models.DecimalField(decimal_places=5,max_digits= 1500)
summary = models.TextField()
featured = models.BooleanField()
def __str__(self):
return self.title
# return f'product title:{self.title}-product price:{self.price}'workok
class Meta:
ordering = ('-price',)
class Opinion(models.Model):
name = models.CharField(max_length=20)
email = models.EmailField(max_length=20)
body = models.TextField()
opinion_date = models.DateTimeField(auto_now_add=True)
active = models.BooleanField(default=False)
product = models.ForeignKey(Product, on_delete=models.CASCADE, related_name='opinion_set')
def __str__(self):
return f'({self.name}) add opinion about ({self.product})'
forms.py:
from django.forms import ModelForm
from .models import Product #space after from keyword
class OpinionModelForm(ModelForm):
class Meta:
model = Product
fields = ['name','email','body','product']
invalid in code line :
fields = ['name','email','body','product'] #---- NOT WORK !!!
, but if i change above code to :
fields = "__all__" # ----it is WORKing ok without any problem !!
question : what is the error? I am not need all the fields in the Product model (like active boolean field), I need only 'name','email','body','product' fields .

Answer 1

According to the error and the code you provided the main problem is that you made a mistake in chosing model in serializer:
class OpinionModelForm(ModelForm):
class Meta:
model = Product
fields = ['name','email','body','product']
Serializer name is OpinionModelForm and listed fields belong to Opinion so I guess you actually wanted to serialize Opinion and no Product as you defined at this line:
model = Product
Simply change it to:
model = Opinion
