Django表单未在POST中提交

遇到无法将文件上传到表单的问题。从我自己的角度来看，这是因为我没有在POST中提交（因为除非您处于POST状态，否则不会保存上载的文件），但我不知道为什么会这样。这是我的代码：

Views.py

def commission(request):
if request.method == "POST":
    form = CommissionForm(request.POST)

    if form.is_valid():
        subject = str(form.cleaned_data.get("name")) + "'s commission request"
        message = form.cleaned_data.get("name") + ",\nhas requested a commission, with the following request:\n" + form.cleaned_data.get("request") + "\n Reply to them using their email:\n" + form.cleaned_data['email']
        email = form.cleaned_data['email']
        print(form.cleaned_data)
        attach = request.FILES['reference']
        try:
            mail = EmailMessage(subject, message, settings.EMAIL_HOST_USER, [email])
            if attach != None:
                mail.attach(attach.name, attach.read(), attach.content_type)
            mail.send()
            return redirect("main-commissions-success")
        except:
            return render(request, "main/commissions.html", {"form": form})
    return render(request, "main/commissions.html", {"form": form})

else:
    form = CommissionForm()

return render(request, "main/commissions.html", {"form": form})

Commissions.html

<div class="row">
    <div class="content-section card w-50 mx-auto my-5">
        <div class="card-body">
            <form method="POST" action="" class="border border-light m-10" enctype="multipart/form-data">
                {% csrf_token %}
                <fieldset class="form-group">
                    <legend class="border-bottom mb-4 text-center">Request A Painting</legend>
                    {{ form|crispy }}
                </fieldset>
                <div class="form-group text-center">
                    <button class="btn btn-outline-info" type="submit">Send Request</button>
                </div>
            </form>
        </div>
    </div> 
</div>

并且由于这没有模型关系，因此我不会在这里添加它。希望有人可以指出我犯的任何愚蠢的错误。
