Question

我正在尝试将“true / false”复选框的默认值更改为另一个。

不幸的是。我收到一个表单错误：“选择不是可用选项之一”。

请告诉我，我做错了什么？

models.py

CHECKBOX_CHOICES = (('1', 'The first choice'), ('2', 'The Second Choice'))

class Order(models.Model):
        paid = models.CharField(max_length=350, choices=CHECKBOX_CHOICES)

forms.py

from django import forms
from .models import Order

class OrderCreateForm(forms.ModelForm):
    class Meta:
        model = Order
        fields = ['paid']
 widgets = {
            'paid': forms.CheckboxSelectMultiple()
        }

如果我将forms.CheckboxSelectMultiple()更改为forms.CheckboxInput()，则会收到表单错误：

Select the correct value. True is not one of the choices available.

create.html上

  <form action="." method="post" class="order-form">
    {{ form.as_ul }}
    <p><input type="submit" value="Submit"></p>
    {% csrf_token %}
  </form>

呈现HTML

<ul id="id_paid">
    <li><label for="id_paid_0"><input type="checkbox" name="paid" value="" checked="" id="id_paid_0">
 ---------</label>
</li>
    <li><label for="id_paid_1"><input type="checkbox" name="paid" value="1" id="id_paid_1">
 The first choice</label>
</li>
    <li><label for="id_paid_2"><input type="checkbox" name="paid" value="2" id="id_paid_2">
 The Second Choice</label>
</li>
</ul>

这对我来说很重要，即使这是一件小事。

Django形成小部件，选择不是可用的选择之一
