django中的单选按钮

udaykls • 5 年前 • 1878 次点击

试图寻找解决方案,但我有一个不同的问题,找不到任何相关的我用models.py中的字段创建了一个django表单

表单.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',
        ]

用这个我看不到页面上的单选按钮我试过了

    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))

这告诉我答案没有定义

这是我的模特

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)

另外,我需要在Meta类中再次定义答案吗?一开始我没有做,我试着解决上面的问题,但还是做不到。

您的模型很好,可以删除自定义字段 division_check 只需更改窗体中的小部件和标签 Meta

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?',
    }

你定义了 answer 在你的 Meta 类,但在定义小部件时,这不在范围内。

可以参照模型中的选项,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',
        ]
