表单不注册照片 Django 3.0

Question

我正在尝试上传照片，但表单看不到该文件，并且在form.errors中，它说"此字段是必填的"。我尝试使用picture = request.FILES['picture']无济于事，也尝试了picture = form.FILES['picture']以及picture = request.POST.FILES['picture']和picture = form.cleaned_data.get('picture')我错过了什么？如果您需要更多信息，请告诉我

模板

{% block content %}
<h1>Create {{post_type.title}} Post</h1>
<form method="post" enctype="multipart/form-data">
{% csrf_token %}
{{form.as_p}}
<button type='submit'>Submit</button>
</form>
{% endblock %}

forms.py

class PicturePostForm(forms.ModelForm):
class Meta:
model = PicturePost
fields = ('description', 'privacy', 'picture', 'categories')

views.py

@login_required()
def picture_post(request):
"""
Creates new picture post
"""
if request.method == "POST":
form = PicturePostForm(request.POST)
print("is post")
if form.is_valid():
print("is valid") # this never gets printed because of the 'this field is required' error
author = request.user
content = form.cleaned_data['description']
category = form.cleaned_data['categories']
picture = form.cleaned_data['picture']
privacy = form.cleaned_data['privacy']
p_post = PicturePost(author=author, description=content, categories=category, picture=picture,privacy=privacy )
p_post.save()
#redirect to last page
return redirect('home')
else:
l = []
for i in form.errors.keys():
l.append(form.errors[i])
return HttpResponse(l)
else:
post_type = 'picture'
form = PicturePostForm()
return render(request, 'create_post.html', {'form': form, 'post_type': post_type})

对应的模型字段

picture = models.ImageField(upload_to=f'profiles/{User}_gallery', max_length=255)

Answer 1

通过将form = PicturePostForm(request.POST)替换为form = PicturePostForm(request.POST, request.FILES)来修复它

Answer 2

我之前尝试过完成代码，请遵循

视图

@login_required()
def picture_post(request):
"""
Creates new picture post
"""
form = PicturePostForm(request.POST or None, request.FILES or None)
if request.method == "POST":
if form.is_valid():
# instance new object p_post (this best practice if using forms.ModelForm)
# commit=False (to save data on ram/memory device without database/hardrive)
p_post = form.save(commit=False)
# assign author attribute from thr current user session
p_post.author = request.user
# commit=True to move/save data from memory to harddrive
p_post.save() # p_post.save(commit=True)
return redirect('home')
else:
l = []
for i in form.errors.keys():
l.append(form.errors[i])
return HttpResponse(l)
post_type = 'picture'
return render(request, 'create_post.html', {'form': form, 'post_type': post_type})
