Question

我创建了一个具有几个字段的模型表单，并希望在用户向模板中输入值并单击提交时保存数据。但是，当我单击“提交”时，值不会从表单中清除，并且数据也不会保存到我使用select * from notes_note;

检查的sqlite3数据库中

我没有收到任何错误，只是没有保存该数据。

Models.py

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

# Create your models here.
class Note(models.Model):
    owner = models.ForeignKey(User, on_delete=models.DO_NOTHING,)
    title = models.CharField(max_length=100)
    text = models.CharField(max_length=500)
    createTime = models.DateTimeField()

from django.forms import ModelForm

class NoteForm(ModelForm):
    class Meta:
        model = Note
        #fields = '__all__'
        #fields = ['title', 'text', 'createTime']
        exclude = ['owner']

模板

<a href="/notes/logout/">Log Out</a>
<h2>Dashboard {{ user }}</h2>

<table>
    <tr>
        <td>
            <form_name="noteForm" action="/notes/dashboard/" method="post"> {% csrf_token %}
                {{ form.as_p }}
                <input type= "submit" value="New Note"/>
            </form>
        </td>
    </tr>
</table>

Views.py

@login_required(login_url="/notes/index/")
def dashboard(request):
    if request.method == 'POST':
        # d dict is a copy of our request.Post because it's immutable and we need to add owner
        d = request.POST.copy()
        d.update({'owner': request.user.id})
        form = NoteForm(d)
        if not form.is_valid():
            template = loader.get_template('dashboard.html')
            context = {
                'form': form,
            }
            return HttpResponse(template.render(context, request=request))
        # save the note to the database
        # if the form is valid
        note = form.save()
        note.owner = request.user
        note.save()
        return redirect("dashboard")
    else:
        print("this prints out")
        template = loader.get_template('dashboard.html')
        context = {
            'form': NoteForm(),
        }
        return HttpResponse(template.render(context, request=request))

我在views.py的仪表板功能中使用了一条打印语句，以查看正在处理的内容，并且该内容正在其他部分。
