Django - form.save() 没有创建 ModelForm [英] Django - form.save() is not creating ModelForm

问题描述

在我的 Django 应用程序中，用户发送有关任务的反馈.我正在用 ModelForm 创建这个 form，在 form.save() 之后，我的对象没有创建，也没有上传到数据库.这是我的代码:

views.py:

@login_required(login_url='sign_in')def task_details(请求，slug):如果弹头:task = get_object_or_404(Task, slug=slug)今天 = datetime.now().date()截止日期 = task.task_deadline.date()time_left = 截止日期 - 今天表单 = CreateFeedbackForm()如果 request.method == 'POST':表单 = CreateFeedbackForm(request.POST)如果 form.is_valid():表单.save()返回重定向('索引')别的:表单 = CreateFeedbackForm()messages.info(请求，'反馈已发送.')上下文 = {'任务':任务，'形式':形式，'days_left': time_left.days}返回渲染(请求，'task-details.html'，上下文)

models.py:

class TaskFeedback(models.Model):任务=models.ForeignKey(任务，on_delete=models.CASCADE，空=真，空白=真)发件人 = CurrentUserField()is_solved = models.BooleanField(默认=假)反馈内容 = 模型.TextField(max_length=1000, null=True, blank=True)date_ added = models.DateTimeField(auto_now_add = True)def __str__(self):返回 self.feedback_content

forms.py:

class CreateFeedbackForm(forms.ModelForm):元类:模型 = 任务反馈字段 = ['feedback_content', 'is_solved']def __init__(self, *args, **kwargs):super(CreateFeedbackForm, self).__init__(*args, **kwargs)

解决方案

问题出在我的 html 页面中的表单操作中:

{% csrf_token %}{{ form.feedback_content }}<div class="panel-buttons"><div class="checkbox">{{ form.is_solved }}

<div class="save-btn-container"><button class="btn btn--pill btn--green" type="submit">发送</button>

</表单>

In my Django application users send feedback about task. I'm creating this form with ModelForm, and after form.save() my object is not creating and is not uploading to database. Here are my codes:

views.py:

@login_required(login_url='sign_in')
def task_details(request, slug):
    if slug:
        task = get_object_or_404(Task, slug=slug)
        today = datetime.now().date()
        deadline = task.task_deadline.date()
        time_left = deadline - today
        form = CreateFeedbackForm()

    if request.method == 'POST':
        form = CreateFeedbackForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('index')
    else:
        form = CreateFeedbackForm()
    messages.info(request, 'Feedback sent.')

    context = {
        'task': task,
        'form': form,
        'days_left': time_left.days
    }
    return render(request, 'task-details.html', context)

models.py:

class TaskFeedback(models.Model):
    task = models.ForeignKey(Task, on_delete=models.CASCADE, null=True, blank=True)
    sender = CurrentUserField()
    is_solved = models.BooleanField(default=False)
    feedback_content = models.TextField(max_length=1000, null=True, blank=True)
    date_added = models.DateTimeField(auto_now_add = True)

    def __str__(self):
        return self.feedback_content

forms.py:

class CreateFeedbackForm(forms.ModelForm):
    class Meta:
        model = TaskFeedback
        fields = ['feedback_content', 'is_solved']

    def __init__(self, *args, **kwargs):
        super(CreateFeedbackForm, self).__init__(*args, **kwargs)

解决方案

The problem was in action of form in my html page:

<form action="{% url 'task_details' task.slug %}" method="POST">
            {% csrf_token %}
            {{ form.feedback_content }}
            <div class="panel-buttons">
                <div class="checkbox">
                    {{ form.is_solved }}
                </div>
                <div class="save-btn-container">
                    <button class="btn btn--pill btn--green" type="submit">Send</button>
                </div>
            </div>
        </form>
