表单数据未保存到数据库

  • 772

我无法确定到底是什么问题。有一个表格：

<form class="form-cr" action="{% url 'events:create_event' %}" method="post" enctype="multipart/form-data" id="MyForm">
                {% csrf_token %}
                <div class="cont-a">
                    <div class="name name">
                        <label for="id_title">Название*</label>
                        <input class="inner-input" type="text" name="title" id="id_title" placeholder="Введите название" required autocomplete="off" value="{% if form.title.value %}{{ form.title.value}}{% endif %}">
                    </div>
                    <div class="url name">
                        <label for="id_slug">Url-адрес*</label>
                        <input class="inner-input" type="text" id="id_slug" name="slug" placeholder="Заполняется автоматически" value="{% if form.slug.value %}{{ form.slug.value}}{% endif %}">

                        <input class="time-inp" type="number" name="day" id="id_day" placeholder="день" required value="{% if form.day.value %}{{ form.day.value}}{% endif %}">
                        <input class="time-inp" type="text" name="month" placeholder="месяц" required value="{% if form.month.value %}{{ form.month.value}}{% endif %}" id="id_month">

                    </div>
                </div>
            </form>

表现：

def edit_event(request, slug, day, month, hours):

    if not request.user.has_perm('events.change_events'):
        raise PermissionDenied
        
    event = Events.objects.get(slug=slug, day=day, month=month, hours=hours)
    if request.method == 'POST':
        form = EventForm(request.POST, request.FILES, instance=event)
        if form.is_valid():
            form.save()
            return redirect('events:home')
    else:
        form = EventForm(instance=event)
    context = {
        'title': 'Event - Edit',
        'form': form,
        'event': event
        }
    return render(request, 'events/edit_event.html', context)

当您单击“Create”时，会执行“create_event”函数，但数据不会传输到数据库，并且不会执行“form.save()”之后的重定向，控制台仅显示：“POST /events”。 /创建事件/ HTTP /1.1" 200 56891

    事实证明整个要点是forms.py：

    class EventForm(forms.ModelForm):
    title = forms.CharField()
    slug = forms.SlugField()
    poster = forms.FileField()
    description = forms.CharField(required=False)
    age = forms.CharField(required=False)
    genre = forms.CharField(required=False)
    day = forms.IntegerField()
    month = forms.CharField()
    hours = forms.CharField()
    class Meta:
        model = Events
        fields = (
            'title',
            'slug',
            'poster',
            'description',
            'age',
            'genre',
            'day',
            'month',
            'hours'
        )

    ModelForm默认情况下，所有字段都是必填的，即使模型指定了blank=True和null=True，并且对于可选字段，您必须明确指出这一点：required=False
