如何从django中的表单中获取数据？

Question

我的模板django中有一个表单没问题，它可以在模型中保存。那么，现在，我想在这个表单中创建一个新表单。这个表单，我在模板内创建，但现在，我想让de数据保存在另一个模型中。 （我不能使用formset，我已经准备好使用它了）。当用户单击列表中的选项时，将使用javascript创建此表单。

我正在使用基于类的视图来创建视图。

我的问题是，如何从用户动态创建的表单中获取此数据？

    <div class="form-group">

        <label class="col-sm-2 control-label">{{form.name.label}}</label>
        <div class="col-sm-10">
        {{form.name}}
        {% if form.name.errors %}
            <span class="glyphicon glyphicon-remove form-control-feedback"></span>
                <span class="help-block">{{form.name.errors.as_text}}</span>
        {% endif %}
        </div>

        <label class="col-sm-2 control-label">{{form.date_max.label}}</label>
        <div class="col-sm-10">
        {{form.date_max}}
        {% if form.date_max.errors %}
            <span class="glyphicon glyphicon-remove form-control-feedback"></span>
                <span class="help-block">{{form.date_max.errors.as_text}}</span>
        {% endif %}
        </div>

        <label class="col-sm-2 control-label">{{form.demand_desc.label}}</label>
        <div class="col-sm-10">
        {{form.demand_desc}}
        {% if form.demand_desc.errors %}
            <span class="glyphicon glyphicon-remove form-control-feedback"></span>

在@mrnfrancesco的评论之后，我应用以下逻辑来保存数据模型：

class CreateDemandView(FormView):
...
    def form_valid(self, form):
        demand = form.save(commit=False)
        demand.save()

        format_name = self.request.POST.getlist('format_name')

        for i in format_name:
            fields_name = self.request.POST.getlist('field_name_' + i)
            format_name_id = NewFormatByStore.objects.get(pk=i)
            data_content_field = self.request.POST.getlist('field_format_data_' + i)

            j = 0 
            while j < len(fields_name):
                format_data_demand = FomartWithDataFromDemand(demand_name=demand, format_name=format_name_id, field_name=fields_name[j], field_format_data=data_content_field[j])
                format_data_demand.save()
                j += 1

...

我从POST获取数据并将相应的数据保存在模型中。
