使用Django-crispy-forms时Create函数不起作用

Question

我的应用程序中有一个产品模型，我已经创建了一个forms.py文件和一个视图函数，以便在其中创建一个对象。然后我在我的模板中使用它。填写所有字段并按submit后，页面只会重新加载，而不会创建产品对象。

models.py

class Product(models.Model):
    name = models.CharField(max_length=36)
    price = models.PositiveIntegerField()
    description = models.TextField()
    quantity = models.PositiveIntegerField()
    image = models.ImageField()
    user = models.ForeignKey(User, on_delete=models.CASCADE)

    def __str__(self):
        return self.name

forms.py

from django import forms
from .models import *

class AddProductForm(forms.ModelForm):
    class Meta:
        model = Product
        fields = '__all__'

views.py

def Addproduct(request):

    form = AddProductForm()
    if request.method == 'POST':
        form = AddProductForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            messages.success(request, "Products Added Successfully")
            return redirect('product')

    context = {"form":form}

    return render(request, "core/addproduct.html", context)

addproduct.html

<form method="post">
{% csrf_token %}
<div class="form-row">
  <div class="form-group col-md-4 mb-0">
    {{ form.name|as_crispy_field }}
  </div>
  <div class="form-group col-md-4 mb-0">
    {{ form.price|as_crispy_field }}
  </div>
  <div class="form-group col-md-4 mb-0">
    {{ form.quantity|as_crispy_field }}
  </div>
</div>
{{ form.description|as_crispy_field }}
<div class="form-row">
  <div class="form-group col-md-6 mb-0">
    {{ form.image|as_crispy_field }}
  </div>
  <div class="form-group col-md-6 mb-0">
    {{ form.user|as_crispy_field }}
  </div>
</div>
<button class="au-btn au-btn--block au-btn--green m-b-20" type="submit">Add Product</button>
</form>

我可以通过将enctype="multipart/form-data"添加到表单来解决这个问题。

<form method="post" enctype="multipart/form-data">
  {% csrf_token %}
  <div class="form-row">
    <div class="form-group col-md-4 mb-0">
      {{ form.name|as_crispy_field }}
    </div>
    <div class="form-group col-md-4 mb-0">
      {{ form.price|as_crispy_field }}
    </div>
  </div>
  <button class="au-btn au-btn--block au-btn--green m-b-20" type="submit">Add Product</button>
</form>
