Question

我想根据复选框选择添加多个复选框以在视图中过滤花朵。我在Django非常棒。如何修改models.py？

from django.db import models

class Flower(models.Model):
    name = models.CharField(max_length = 30)
    price = models.DecimalField(max_digits=6, decimal_places=2)
    details = models.TextField()

    def __unicode__(self):
        return self.name
    def my_upload_to(instance, filename):
        return 'static/media/' + instance.name + '.jpg'
    image = models.ImageField(upload_to=my_upload_to)

Answer 1

您可以使用表单完成，这里是代码：

from django.forms import widgets
class FlowerForm(forms.ModelForm):
    name = forms.ModelMultipleChoiceField(label='Name',queryset=Flower.objects.all(),
           widget=forms.CheckboxSelectMultiple)
    class Meta:
        model = Flower

Answer 2

有些事情是这样的：

在views.py中

：

# get the selected flower id as fid
FlowerForm = create_flower_form(fid)

form.py中的

：

def create_flower_form(id):
class fform(forms.ModelForm):

    name = forms.ModelChoiceField(label='Flower type ',
            queryset=FLower.objects.filter(id=fid))


    class Meta:

        model = Flower

return fform

将多个Checkbox组添加到Django管理面板
