Django Form 没有更新数据库

Question

我正在制作一个表单网站。但我的输入没有被添加到数据库中。它以前有用，但现在不行了。我所做的最后一次阻止它工作的更改是我表单中的 URL，因此当我提交表单时它可以转到另一个页面。

我的 html 模板是这样的

<div class="form-container">
    <form enctype="multipart/form-data" action="/succes/" method="POST">
    .....

在我添加这个之后它停止工作了添加 {%url 'Form:thank'%} 后一切都变糟了。

<div class="form-container">
    <form enctype="multipart/form-data" action="{%url 'Form:thank'%}" method="POST">
    ......

老实说，我现在迷路了。并且不知道如何解决这个问题。我是 Django 开发新手（所以我可能漏掉了什么）

urls.py

 app_name =  'Form'
 urlpatterns = [
   path('', FormPage, name = "Home"),
]

当然，我删除了感谢页面以恢复到以前的状态。感谢页面正在运行。如果你想知道

models.py

class Form(models.Model):
company_name = models.CharField(max_length=200, null=False, blank=False)
first_name = models.CharField(max_length=100)

        print(form.is_valid())
        print(form.errors)
else:
    form = Form()
    inputs = FileInput()

dic = {
    'form': form,
    'fileinputs': FileInput
}
return render(request, 'formpage.html', {'dic': dic})

    widgets ={

Answer 1

action="…" 应该引用 FromPage，因为这是处理该表单的 POST 请求的视图。因此，这意味着您将其指定为：

<form enctype="multipart/form-data" <strong>action="{% url 'Form:Home' %}"</strong> method="POST">
    …
</form>

然后在视图中处理将数据保存到数据库的逻辑，然后您可以 return 重定向响应到 thank-you 页面:

from django.shortcuts import <b>redirect</b>

def FormPage(request):
    if request.method == 'POST':
        form = Form(request.POST)
        if form.is_valid():
            bigform = form.save(commit=False) 
            print(f'is this even working {form}')
            for f in request.FILES.getlist('files'):
                inputs = FileInput(request.FILES, request.POST)
                if inputs.is_valid():
                    fileinp = inputs.save(commit=False)
                    fileinp.files = f
                    fileinp.form_fk = bigform
                    fileinp.save()
            # redirect to the Form:thank view
            return <strong>redirect('Form:thank')</strong>
    else:
        form = Form()
        inputs = FileInput()
    
    dic = {
        'form': form,
        'fileinputs': FileInput
    }
    return render(request, 'formpage.html', {'dic': dic})

redirect('Form:thanks') 会将浏览器重定向到感谢页面。
