Question

我是Django的新手，我研究了如何创建下拉列表。我尝试了所有方法，但仍然没有在HTML视图中显示下拉列表。我的示例脚本就是这个。

这是model.py

from django.db import models

class samplemodel(models.Model):
    list = (
            ('sample1','SAMPLE1'),
            ('sample2','SAMPLE2'),
        )

    list_choices = models.CharField(max_length=6, choices=list)

forms.py

from .models import samplemodel
from django.forms import ModelForm

class sampleForm(ModelForm):
    class Meta:
        model = samplemodel
        fields = ['list_choices']

这是views.py

from django.shortcuts import render
from .models import samplemodel
from .forms import sampleForm
from django.views.generic import CreateView


class sampleView(CreateView):
    model = samplemodel
    form_class = sampleForm
    template_name = 'home/sample.html'

这是home.html

{% extends 'base.html' %}

{% block head %}
<title>Home</title>
{% endblock %}

{% block body %}

<div class="container">
    <form class="post">
        {% csrf_token %}
        {{ form.as_p }}
    </form>
</div>

{% endblock %}

我尝试了我在互联网上看到的一切。但我仍然无法显示下拉菜单。我不知道imports是否是问题。

你的模特应该是这样的

＆＃13;

from django.db import models
class SampleModel(models.Model):
    list = (
            ('sample1','SAMPLE1'),
            ('sample2','SAMPLE2'),
        )

    list_choices = models.CharField(max_length=6, choices=list)

＆＃13;

你的urlconf中的

＆＃13;

from django.views.generic import CreateView
from app.models import Samplemodel
from django.forms import ModelForm
url(r'^sample_form$',CreateView.as_view(model=SampleModel, template_name='home/sample.html', success_url='index', name='sample_form'))

＆＃13;

这就是你不需要forms.py。 django将照顾一切

下拉模型没有在html视图中显示 - Django
