Question

试图寻找解决方案，但我遇到了另一个问题，找不到与之相关的任何东西我已经使用来自models.py

的字段创建了一个django表单

forms.py

from .models import ProValue
from django import forms


class SchoolInput(forms.ModelForm):
    school_name = forms.CharField(
        max_length=255, required=True, widget=forms.TextInput(
            attrs={
                'class': 'input'
            }
        ))
    level_of_grades = forms.IntegerField(min_value=1, required=True)
    num_of_days = forms.IntegerField(min_value=1, max_value=7, required=True)
    division_check = forms.ChoiceField(
        label='Do you have multiple divisions for your grades?', widget=forms.RadioSelect)

    class Meta:
        model = ProValue
        answer = (
            ('no', 'no'),
            ('yes', 'yes')
        )
        fields = [
            'school_name',
            'level_of_grades',
            'num_of_days',
            'division_check',
        ]

这样，我在页面上看不到单选按钮我已经尝试过了

    division_check = forms.ChoiceField(
        label='Do you have multiple divisions for your grades?', widget=forms.RadioSelect())

和

    division_check = forms.ChoiceField(
        label='Do you have multiple divisions for your grades?', widget=forms.RadioSelect(choice=answer))

这告诉我答案未定义

这是我的模特。py

from django.db import models
from django import forms


class ProValue(models.Model):
    school_name = models.CharField(max_length=50)
    level_of_grades = models.IntegerField()
    num_of_days = models.IntegerField()
    answer = (
        ('Yes', 'Yes'),
        ('No', 'No'),
    )
    division_check = models.CharField(
        max_length=5, choices=answer)

此外，我是否需要再次在Meta类中定义答案？起初我没有这样做，我试图解决上述问题，但仍然无法解决。

Answer 1

您在answer类中定义了Meta，但是在定义窗口小部件时不在范围内。

您可以引用模型中的选项，例如：

from .models import ProValue
from django import forms


class SchoolInput(forms.ModelForm):
    school_name = forms.CharField(
        max_length=255, required=True, widget=forms.TextInput(
            attrs={
                'class': 'input'
            }
    ))
    level_of_grades = forms.IntegerField(min_value=1, required=True)
    num_of_days = forms.IntegerField(min_value=1, max_value=7, required=True)
    division_check = forms.ChoiceField(
        label='Do you have multiple divisions for your grades?',
        choices=ProValue.answer,
        widget=forms.RadioSelect
    )

    class Meta:
        model = ProValue
        fields = [
            'school_name',
            'level_of_grades',
            'num_of_days',
            'division_check',
        ]

Answer 2

您的模型很好，您可以从表单中删除自定义字段division_check，只需更改表单Meta中的小部件和标签即可

class Meta:
    model = ProValue
    fields = [
        'school_name',
        'level_of_grades',
        'num_of_days',
        'division_check',
    ]
    widgets = {
        'division_check': forms.RadioSelect,
    }
    labels = {
        'division_check': 'Do you have multiple divisions for your grades?',
    }

Django中的单选按钮
