一、启用media

在 Django 的开发中有两个特殊的文件夹：

static：存放静态文件
media：存放用户上传的数据，但是使用 media 需要做一些配置

1、URL设置

re_path(r'^media/(?P<path>.*)$', serve, {'document_root': settings.MEDIA_ROOT}, name='media'),

2、settings.py配置

MEDIA_ROOT = os.path.join(BASE_DIR, "media")
MEDIA_URL = '/media/'

这样设置之后，上一篇可以修改一下

二、url

三、upload.py 新增upload_modelform方法

def upload_modelform(request):
    """modelform上传"""
    title = "ModelForm上传"
    if request.method == 'GET':
        form = UpModelForm()
        # print(form)
        return render(request, 'upload_form.html', {"form": form, "title": title})
    form = UpModelForm(data=request.POST, files=request.FILES)
    if form.is_valid():
        form.save()

        redirect('/city/list/')
    return render(request, 'upload_form.html', {"form": form, "title": "form上传"})

四、form.py新增UpModelForm


class UpModelForm(BootStrapModelForm):
    #  img 字段不使用bootstrap样式
    bootstrap_exclude_fields = ['img']
    class Meta:
        model = models.City
        fields = "__all__"

五、创建city表


class City(models.Model):
    """城市"""
    name = models.CharField(verbose_name='名称', max_length=32)
    count = models.IntegerField(verbose_name='人口')
    # FileField本质上也是CharField，FileField自动保存数据
    img = models.FileField(verbose_name='LOGO', max_length=128, upload_to='city/')

六、创建city_list.html

{% extends 'layout.html' %}
{% block title %}
    <title>城市列表</title>
{% endblock %}
{% block content %}
    <div class="container">
        <div style="margin-bottom: 10px">
            <a class="btn btn-success" href="/upload/modelform/">

                               value="{{ search_data }}">

                        </span>

                    城市列表
                </div>

                <!-- Table -->
                <table class="table table-bordered">
                    <thead>
                    <tr>

                    <tbody>
                    {% for obj in query_set %}
                        <tr>
                            <th scope="row">{{ obj.id }}</th>
                            <td>
                                <img src="/media/{{ obj.img }}" style="height: 80px;">

                            </td>
                            <td>{{ obj.name }}</td>
                            <td>{{ obj.count }}</td>

                        </tr>
                    {% endfor %}
