确定在 Django 表单提交中点击了哪个提交按钮 [英] Identify which submit button was clicked in Django form submit

问题描述

在 Django 中，我想要一个带有 2 个提交按钮选项的表单.保存& 主页"和保存& 下一个".

In Django I would like to have a form with 2 submit button options. "save & home" and "save & next".

有什么想法可以确定在我的视图中点击了哪个提交按钮吗?

Any thoughts how I can identify which submit button was clicked in my view?

我对编程/使用表单还很陌生，非常感谢您的反馈.

I'm fairly new to programming/working with forms and appreciate the feedback.

表格

<form action="{% url 'price_assessment_section_1' component.id %}" method="post"> {% csrf_token %}

 {{ form.s1_q5_resin_type }}

 <!-- FORM SUBMIT BUTTONS-->

 <button type="submit" >&nbsp;Save&Home</button>

 <button type="submit" >&nbsp;Save&Next</button>

</form> <!-- end form-->

查看

@login_required
def price_assessment_section_1(request, component_id):

    component = Component.objects.get(id=component_id)

    if request.method == 'POST':
        form = PriceAssessmentSection1(request.POST)

                # if "save & home" go to: return HttpResponseRedirect(reverse('portal_home'))

                # if "save & next" go to: return HttpResponseRedirect(reverse('portal_sec2'))

    form = PriceAssessmentSection1()
    return render(request, 'portal/price_assessment_section_1.html', {'form': form, 'component':component})

推荐答案

你可以给他们起名字.只有点击的按钮通过提交发送他们的数据.在你的模板中给他们合适的名字:

You can give them names. Only clicked buttons send their data with submit. In your template give them appropriate names:

<button type="submit" name="save_home" value="Save&Home">&nbsp;Save&Home</button>
<button type="submit" name="save_next" value="Save&Next">&nbsp;Save&Next</button>

并且在相关部分的视图中，您可以通过检查其名称来检查点击了哪个按钮.

And in your view in the related section, you can check which button is clicked by checkng its name.

if request.method == 'POST':
    form = PriceAssessmentSection1(request.POST)
    if request.POST.get("save_home"):
        return HttpResponseRedirect(reverse('portal_home'))
    elif request.POST.get("save_next"):  # You can use else in here too if there is only 2 submit types.
        return HttpResponseRedirect(reverse('portal_sec2'))
