django文件——django + jquery-file-upload上传篇（一）-- 插件实现文件上传
django + jquery-file-upload 插件实现文件上传
1.model.py
class Fujian(models.Model):
name = models.CharField(max_length=32,verbose_name="附件名称")
file = models.FileField(upload_to="upload/%Y/%m/%d/")
uploaded_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.name
2.forms.py
class FujianForm(forms.ModelForm):
class Meta:
model = Fujian
fields = ('file',)
3.views.py
def fujian_add(request):
if request.method == 'POST':
form = FujianForm(request.POST,request.FILES)
if form.is_valid():
fujian = form.save()
data = {'is_valid':True,'name':fujian.file.name,'url':fujian.file.url}
else:
data = {'is_valid':False}
return JsonResponse(data)
if request.method == 'GET':
return render(request,"fujian_add.html")
4.fujian_add.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>附件上传</title>
<link rel="stylesheet" href="/static/bootstrap/css/bootstrap.css">
<script src="/static/js/jquery.min.js"></script>
<script src="/static/js/jquery-ui.min.js"></script>
<script src="/static/bootstrap/js/bootstrap.js"></script>

<script src="/static/jquery-file-upload/jquery.iframe-transport.js"></script>
<script src="/static/jquery-file-upload/jquery.fileupload.js"></script>
<script src="/static/js/base.js"></script>
</head>
<body>
<div class="container">
<h1>图片上传</h1>
<form method="post" action="">
{% csrf_token %}
<input type="hidden" name="next" value="{{ request.path }}">
<button type="submit" class="btn btn-danger pull-right">
<span class="glyphicon glyphicon-trash"></span> 清空数据
</button>
</form>
<div>
<div style="margin-bottom: 20px;">
{# 1. 添加附件的按钮 #}
<button type="button" class="btn btn-primary js-upload-photos">
<span class="glyphicon glyphicon-cloud-upload"></span> 上传附件
</button>
{# 2. 上传图片的插件 #}
<input id="fileupload" type="file" name="file" multiple
style="display: none;"
data-url="/fujian/add/"
data-form-data='{"csrfmiddlewaretoken": "{{ csrf_token }}"}'>
</div>
{# 3. 显示上传的文件 #}
<table id="gallery" class="table table-bordered">
<thead>
<tr>
<th>Photo</th>
</tr>
</thead>
<tbody>
</tbody>
</table>
</div>
</div>
</body>
</html>
页面效果：
5.需要引入jquery-file-upload的js文件
<link rel="stylesheet" href="/static/bootstrap/css/bootstrap.css">
<script src="/static/js/jquery.min.js"></script>
<script src="/static/js/jquery-ui.min.js"></script>
<script src="/static/bootstrap/js/bootstrap.js"></script>
<script src="/static/jquery-file-upload/vendor/jquery.ui.widget.js"></script>
<script src="/static/jquery-file-upload/jquery.iframe-transport.js"></script>
<script src="/static/jquery-file-upload/jquery.fileupload.js"></script>
<script src="/static/js/base.js"></script>
6.urls.py文件
from app01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^fujian/add/$', views.fujian_add),
]
7.base.js文件
$(function () {
/* 1. OPEN THE FILE EXPLORER WINDOW */
$(".js-upload-photos").click(function () {
$("#fileupload").click();
});
/* 2. INITIALIZE THE FILE UPLOAD COMPONENT */
$("#fileupload").fileupload({ //fileupload
dataType: 'json',
done: function (e, data) { /* 3. PROCESS THE RESPONSE FROM THE SERVER 这里的data来自于JsonResponse传来的data*/
if (data.result.is_valid) {
$("#gallery tbody").prepend(
"<tr><td><a href='" + data.result.url + "'>" + data.result.name + "</a></td></tr>"
)
}
}
});
});
补充：
django 的 FileField字段upload参数控制上传的文件存放位置：
1.django在upload_to上内置了strftime（）函数，将upload_to设置成 upload_to="upload/%Y/%m/%d",上传的文件将存放为 upload/2019/05/08/test.png
2.将upload_to 设置成 upload_to = "upload/",上传的文件将存放为 upload/test.png
3.更加高级的设置，django还允许你重写一个upload_to函数，重定义上传文件的路径前缀：
#让上传的文件路径动态地与user的名字有关
def upload_to(instance, fielname):
return '/'.join([MEDIA_ROOT, instance.user_name, filename])
class User(models.Model):
avatar = ImageField(upload_to = upload_to)
user_name = CharField(max_length = 250)
