Question

我正在尝试通过表单向数据库添加对象，但没有任何反应，信息不会出现在db中。这是我的代码，我已经搜索了几个小时，什么都没找到

models.py

    from django.db import models
    import os
    from django import forms
    from django.contrib.auth.models import User

    class Projects(models.Model):
        Cascades = []
        for d, dirs, files in os.walk('pd/haarcascades'):
            for f in files:
                path = os.path.abspath(f) # формирование адреса
                name = os.path.splitext(f)[0]
                file_name_path  = ()
                file_name_path = (path, name)
                Cascades.append(file_name_path)
        ProjectName = models.CharField(max_length = 15)
        ProjectOwner = models.OneToOneField(User, primary_key = True) #
        ProjectType = models.CharField(max_length = 1) # D for Detection , C for Creating Own Cascacde
        CascadeType = models.CharField(max_length = 150, choices=Cascades)
        CascadePath = models.CharField(max_length = 150, null  = True)
        ProjectPath = models.CharField(max_length = 100)# for later downloading
        ProjectReadyFilter = models.BooleanField(default=False)# 0 uncompleted project, 1 - completed

forms.py

    from django import forms
    import os
    from .models import Projects

    class ChosingCascade(forms.ModelForm):
        class Meta:
            model = Projects
            fields = ('ProjectName', 'CascadeType',)

views.py

    class PhotoDetectionProcessView(FormView):
        template_name = "pd/ChosingCascade.html"
        success_url = "/pd/ChosingCascade"
        form_class = ChosingCascade
        def ChosingCascade(request):
            def get(self, request):
                form_class = ChosingCascade()
                return render(request, self.template_name, {'form_class':form_class})


            def post(self,request):
                form = ChosingCascade(request.POST)
                if form.is_valid():
                    post = form.save(commit = False)
                    UserName = request.user
                    post.ProjectOwner = request.user
                    post.ProjectName = form.cleaned_data.get("ProjectName")
                    post.CascadeType = CascadeType(initial={'origin':ChosingCascade.Cascades[1]})
                    post.CascadePath = CascadeType(initial={'origin':ChosingCascade.Cascades[0]})
                    post.ProjectType = 'D'
                    os.makedirs('users/%s/PhotoDetection/%s', UserName, ProjectName)
                    post.ProjectPath = ('users/%s/PhotoDetection/%s', UserName, ProjectName)
                    post.save()
                    form= ChosingCascade()
                    return redirect('pd/ChosingCascade: pd/ChosingCascade')
                args = {'form':form }
                return render(request, self.template_name, args)

ChosingCascade.html

    <html>
    <head>
    <meta charset="UTF-8">
    <title>Chosing Cascade</title>
    </head>
    <body>
      <form action="" method="post">
        {% csrf_token %}
        {{ form.as_p }}
        <input type="submit" value="Vote" />
    </form>
    </body>
    </html>

这个想法是关注：用户创建项目，输入名称并选择haarcascade，但是当我按下＆＃34;投票＆＃34; db

中没有数据出现

将数据从表单保存到数据库django
