Django文件上传

在Django中实现文件上传，首先需要在models.py中定义一个模型，包含用于存储上传文件的FileField或ImageField字段。然后在forms.py中创建一个表单，使用FileField或ImageField字段。在views.py中处理上传的文件，并在urls.py中配置相应的URL路径。

以下是一个简单的例子：

models.py:

from django.db import models
 
class Document(models.Model):
    uploaded_file = models.FileField(upload_to='documents/')

forms.py:

from django import forms
from .models import Document
 
class DocumentForm(forms.ModelForm):
    class Meta:
        model = Document
        fields = ('uploaded_file',)

views.py:

from django.shortcuts import render
from django.http import HttpResponseRedirect
from .forms import DocumentForm
from .models import Document
 
def upload_file(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/success/url/')
    else:
        form = DocumentForm()
    return render(request, 'upload.html', {'form': form})

upload.html:

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Upload file</button>
</form>

urls.py:

from django.urls import path
from .views import upload_file
 
urlpatterns = [
    path('upload/', upload_file, name='upload_file'),
]

确保你的MEDIA\_ROOT和MEDIA\_URL设置在settings.py中正确配置，以便能够访问上传的文件。
