Python 如何设置在django或使用哪个小部件中有选择的charfield的样式？

好的，我真正想做的是设计一个charfield，它可以从forms.py modelform类中进行选择

My models.py有这段代码它

from django.db import models
from django.contrib.auth.models import User


# Create your models here.
cat_choices = (
    ("Stationary","Stationary"),
    ("Electronics","Electronics"),
    ("Food","Food"),
)

class Product(models.Model):
    name = models.CharField(max_length=100,null=True)
    category = models.CharField(max_length=100, choices=cat_choices,null=True)
    quantity = models.PositiveIntegerField(null=True)

    class Meta:
        verbose_name_plural = 'Product'
        ordering = ['category']

我的forms.py有

from django import forms
from .models import Product

class AddProduct(forms.ModelForm):
    class Meta:
        model = Product
        fields = ['name','category','quantity']

    def __init__(self, *args, **kwargs):
        super(AddProduct,self).__init__(*args, **kwargs)
        self.fields['name'].widget = forms.TextInput(attrs={'type':'text','id':'name','name':'name','class':'form-control','placeholder':'Product Name'})
        # self.fields['category'].widget = forms.Select(attrs={'class':'form-select'})

因此，我需要一个解决方案，我可以如何风格它或更适当地使用哪个小部件。我已尝试选择，但它不起作用。

您应该将模型中的

类别更改为
整型字段
：

cat_choices = (
    (0, "Stationary"),
    (1, "Electronics"),
    (2, "Food"),
)

class Product(models.Model):
    ...
    category = models.IntegerField(choices=cat_choices, null=True)
    ...

然后您可以使用
表单。选择
