如何在Django模板中传递的发布数据中接收字典

Question

下面是我的模特：

class Person(models.Model):
    number = models.ForeignKey(Admfiles, on_delete=models.CASCADE,  blank = False)
    name = models.CharField(max_length = 255,  blank = False)
    situation= models.CharField(max_length = 20, blank = False)

在我的模板中，输入是使用js附加输入动态创建的，所以我不知道字典的长度。

<input name="person[0][name]"      value="...">
<input name="person[0][situation]" value="...">
<input name="person[1][name]"      value="...">
<input name="person[1][situation]" value="...">
<input name="person[n][name]"      value="...">
<input name="person[n][situation]" value="...">

如果执行，我将收到正确的值：

return HttpResponse(request.POST.get('person[0][name]'))
return HttpResponse(request.POST.get('person[0][situation]'))

如何迭代将n元素保存到模型中？

Answer 1

如果我正确理解了您的问题，则可以如下获取整个POST数据：

data = request.POST.dict()

然后您可以遍历此字典并保存对象。

for key in data:
   value = data['key']
   # save the element in your database

我终于使用了表单集库。 （首先安装pip ...）

Setting.py：

INSTALLED_APPS = [
    'djangoformsetjs',
]

我的表格：

from django.forms import inlineformset_factory

class CrearImputadoForm(forms.ModelForm):
    class Meta:
        model = Imputado
        fields = '__all__'

ImputadoFormset = inlineformset_factory(
    Expediente,
    Imputado,
    extra=1
)

我的看法：

class CrearImputado(CreateView):
    model = Imputado
    form_class = CrearImputadoForm
    template_name = 'crear_imputado.html'

    def get_context_data(self,**kwargs):
        context = super().get_context_data(**kwargs)
        context['formset'] = ImputadoFormset(queryset=Imputado.objects.none())
        context['expedientes'] = Expediente.objects.filter(id = self.kwargs['pk'])
        return context

    def post (self, request, * args, ** kwargs):
        #return HttpResponse(request.POST.items())
        expediente = Expediente.objects.get(pk=request.POST.get('numero_id'))
        form = ImputadoFormset(request.POST, instance=expediente)
        if form.is_valid():
            #return HttpResponse(request.POST.items())
            form.save()
            return redirect('repositorio:crear_delito', request.POST.get('numero_id'))
        else:
            #return HttpResponse(request.POST.items())
            return render(request, self.template_name, {'form': form, 'mensaje':'Ocurrió un error. Contáctese con el administrador.'})

模板：

            <table class="table table-striped">
                {{ formset.management_form }}
                {% for form in formset %}
                    {% if forloop.first %}
                        <thead>
                        <tr>
                            {% for field in form.visible_fields %}
                                <th>{{ field.label|capfirst }}</th>
                            {% endfor %}
                        </tr>
                        </thead>
                    {% endif %}
                    <tr class="{% cycle row1 row2 %} formset_row">
                        {% for field in form.visible_fields %}
                            <td>
                                {# Include the hidden fields in the form #}
                                {% if forloop.first %}
                                    {% for hidden in form.hidden_fields %}
                                        {{ hidden }}                                            
                                    {% endfor %}
                                {% endif %}
                                {{ field.errors.as_ul }}
                                {{ field }}
                            </td>
                        {% endfor %}
                    </tr>
                {% endfor %}
            </table> 


<script type="text/javascript">
    $('.formset_row').formset({
        addText: 'Nuevo Imputado',
        deleteText: 'Borrar',
        prefix: 'imputado_set'
    });
</script>

And finally import jquery.formset.js.

I don't know if it's the best way, but works fine.
