如何在不使用Django窗体的情况下存储图像

Question

html格式：

<form action = "{% url 'newcomplaint' %}" class = 'newc' method = "post" enctype = "multipart/form-data" >
    { % csrf_token % }

    <div class = "form-group" >
    <label for = "fileToUpload" > Add an image(optional) < /label >
    <input type = "file" name = "fileToUpload" id = "fileToUpload" >
    </div >

    <button type = "submit" class = "btn btn-dark bb" > Post New Complaint < /button >
</form >

views.py： 我在这里得到MultiValueDictKeyError at /hood/new

def newcomplaint(request):
    if request.method == "POST":
        # I dont know how to store a image here
        image = request.FILES['fileToupload']
        #print(image)
        return HttpResponse('works')

model.py

from django.db import models
from django.core.exceptions import ValidationError 
from django.contrib.auth.models import User

class Complain(models.Model):
    image = models.ImageField(upload_to='images/', blank=True)
    

我看到的所有解决方案都是使用django表单完成的，我希望避免这种情况，因为我已经制作了一个更大的表单，带有图像字段和一些其他输入（并添加了样式和Js验证检查）

那么如何从表单中检索文件并将其存储在django中

Answer 1

有一个打字错误。你已经写了fileToupload。它应该是fileToUpload

Answer 2

代码期望fileToupload是键，但是表单使用fileToUpload

Answer 3

我打错了，也找到了解决办法how to store a file/image in django without forms

我的工作代码： views.py

def newcomplaint(request):
if request.method == "POST":
    newcomplaint = Complain.objects.create(
        user=request.user,
        title=request.POST['title'],
        content = request.POST['content'],
        ran = request.POST['range'],
        lati = request.POST['lati'],
        longi = request.POST['longi'],
        )

    if len(request.FILES) == 0:
        print('no files')
    else: 
        _, file = request.FILES.popitem()
        file = file[0]
        newcomplaint.image = file
        newcomplaint.save()
    


    return HttpResponse('works')
