Django基于类的CreateView中的Formset

Question

模型

class Timetable(models.Model):
    day = models.CharField(max_length=9,choices=timetable_choices)
    start = models.IntegerField()
    end = models.IntegerField()
    period = models.CharField(max_length=12)

查看

class Timetableadding(CreateView):
    model =  Timetable
    fields = ['day','period','start' ,'end']
    success_url = '/dashboard'

我需要处理类似于下图的视图，

注意：我的JS不好，所以我想要一个不使用JS的解决方案

Answer 1

创建表格

class MyForm(ModelForm): 
    class Meta:
        model = Timetable
        fields = ['day','start','end','period',]

Views.py

from django.forms import formset_factory  
class YourView(CreateView):
    form = formset_factory(MyForm)
    model = Timetable
    success_url ="Your success url"
    template_name = "your template"

在您的模板中

<form method="post">{% csrf_token %}
    <fieldset>
        <div class="row">
            <div class="form-group col-lg-12">             
                {{ form.management_form }}                                          
                {% for contact in form %}
                <div class="link-formset">
                    {{ contact.as_p }}
                </div>
                {% endfor %}
                <button class="user-sent" type="submit" value="Send"> Send</button>
            </div>
        </div>    
    </fieldset>
    <script src="{% static 'forms/jquery.formset.js' %}"></script> 
    <script>
        $('.link-formset').formset({
            addText: '<i class="fa fa-plus"></i> Add User',
            deleteText: '<i class="fa fa-trash-o"></i>Remove'
        });
    </script>
</form>

查看

class Timetableadding(CreateView):
    model =  Timetable
    success_url = '/dashboard/'
    form_class = Timetableform
    template_name = 'form.html'


    def get_context_data(self, **kwargs):
        context = super(Timetableadding, self).get_context_data(**kwargs)
        context['formset'] = TimetableFormSet(queryset=Timetable.objects.none())
        context['day_form'] = DayForm()
        return context

    def post(self, request, *args, **kwargs):
        formset = TimetableFormSet(request.POST)
        day_form = DayForm(data=request.POST)
        if formset.is_valid() and day_form.is_valid():
            return self.form_valid(formset,day_form)

    def form_valid(self, formset,day_form):
        day = day_form.cleaned_data['day']
        instances = formset.save(commit=False)
        for instance in instances:
            instance.day = day
            instance.save()
        return HttpResponseRedirect('/dashboard/')

形式

class DayForm(Form):
    day = ModelChoiceField(queryset=Day.objects.all())


class Timetableform(ModelForm):
    class Meta:
        model = Timetable
        fields = ( 'day','start', 'end', 'period')

TimetableFormSet = modelformset_factory(Timetable, fields=('start', 'end', 'period'),extra=8,)

模板

{% csrf_token %}
{{ day_form }} <br>
{{ formset.management_form }}
{% for form in formset %}
{{ form }}<br><br>
{% endfor %}
