python - Django 1.10 AdminDateWidget() 在ModelForm中的使用

Question

Django 文档并不清楚如何使用 ModelForm。首先，如何设置我的 urls.py？

我只是这样做:

from . import views as music_views
url(r'album/add/$', music_views.AlbumCreate(), name='album-add'),

在我看来，我正在尝试使用 AdminDateWidget:

from . import models as music_models
from django import forms
from django.contrib.admin.widgets import AdminDateWidget
class AlbumCreate(forms.ModelForm):
    class Meta:
        releasedate = forms.DateField(widget=AdminDateWidget())
        model = music_models.Album
        fields = ['artist', 'album_title', 'genre', releasedate, 'notes', 'album_logo', 'rating']

我的模板是:

{% for field in form %}
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <span class="text-danger small">{{ field.errors }}</span>
        </div>
        <label class="control-label col-sm-2">
            {{ field.label_tag }}
        </label>
        <div class="col-sm-10">
            {{ field }}
        </div>
    </div>
{% endfor %}

我在这里遇到的问题是在呈现页面时出现此错误:

Exception Value:    
sequence item 0: expected str instance, DateField found

但是根据https://docs.djangoproject.com/en/1.10/topics/forms/modelforms/ docs，DateField 是允许的数据类型之一。所以我显然以某种方式做错了，但不知道如何做对。有人可以帮我解决这个问题吗？如果可能的话，我倾向于从基础示例中学习。

乍一看，似乎有很多问题(模板中没有表单标签，字段只能接受字符串等)但最重要的是对于那些想使用 AdminDateWidget 的人:您需要加载许多额外的脚本，这些脚本不包含在通常的 {{ form.media }} 中。

project/urls.py

from django.conf.urls import include, url
from album.views import album_add


urlpatterns = [
    url(r'album/add/$', album_add, name='album-add'),
]

album/models.py

from django import forms
from django.db import models
from django.contrib.admin.widgets import AdminDateWidget


class Album(models.Model):
    artist = models.CharField(max_length=30)
    releasedate = models.DateField()


class AlbumForm(forms.ModelForm):
    releasedate = forms.DateField(widget=AdminDateWidget)

    class Meta:
        model = Album
        fields = ['artist', 'releasedate']

album/views.py

from .models import AlbumForm
from django.shortcuts import render, HttpResponse


def album_add(request):
    if request.method == "GET":
        form = AlbumForm()
        return render(request, 'album/create_album.html', {'form': form})
    elif request.method == "POST":
        form = AlbumForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponse("Saved.")
        return render(request, 'album/create_album.html', {'form': form})

album/templates/album/create_album.html

{% load static  %}

<script type="text/javascript" src="/admin/jsi18n/"></script>
<script type="text/javascript" src="{% static 'admin/js/core.js' %}"></script>
<script type="text/javascript" src="{% static 'admin/js/vendor/jquery/jquery.js' %}"></script>
<script type="text/javascript" src="{% static 'admin/js/jquery.init.js' %}"></script>

{{ form.media }}

<link rel="stylesheet" type="text/css" href="{% static 'admin/css/base.css' %}" />
<link rel="stylesheet" type="text/css" href="{% static 'admin/css/widgets.css' %}" />

<form>
    {% csrf_token %}
    <table>
    {{ form }}
    </table>
    <input type="submit" value="Go!">
</form>

我希望这对某人有帮助!
