Django：添加没有javascript的内联formset行 [英] Django: Adding inline formset rows without javascript

问题描述

这篇文章涉及到：
将行添加到在django管理员中动态嵌入

有没有办法在不使用javascript的情况下添加内联表单？显然，会涉及一个页面刷新。

所以，如果表单有一个名为add的按钮...

我想我可以这样做：

  if request.method =='POST'：
如果request.POST：
 PrimaryFunctionFormSet = inlineformset_factory（Position，Function，extra = 1）
 prims = PrimaryFunctionFormSet（request.POST）
  

我以为每次添加1，然后填写表单与帖子数据。然而，似乎extra = 1并没有为post数据添加1。

解决方案

有时这是最简单的解决方案。只需复制request.POST数据并修改TOTAL-FORMS。

例如..

  if request.method =='POST'：
 PrimaryFunctionFormSet = inlineformset_factory（Position，Function）
如果在request.POST中添加：P $ = request.POST.copy（）
 cp ['prim-TOTAL_FORMS'] = int（cp ['prim-TOTAL_FORMS']）+ 1 
 prims = PrimaryFunctionFormSet（cp，prefix ='prim'） 
  

然后只要正常地吐出表单。保存数据，添加内联编辑器。

Is there a way to achive adding inline formsets WITHOUT using javascript? Obviously, there would be a page-refresh involved.

So, if the form had a button called 'add'...

I figured I could do it like this:

if request.method=='POST':
  if 'add' in request.POST:
    PrimaryFunctionFormSet = inlineformset_factory(Position,Function,extra=1)
    prims = PrimaryFunctionFormSet(request.POST)

Which I thought would add 1 each time, then populate the form with the post data. However, it seems that the extra=1 does not add 1 to the post data.

解决方案

Got it.

Sometimes it's the simplest solution. Just make a copy of the request.POST data and modify the TOTAL-FORMS.

for example..

if request.method=='POST':
  PrimaryFunctionFormSet = inlineformset_factory(Position,Function)
  if 'add' in request.POST:
    cp = request.POST.copy()
    cp['prim-TOTAL_FORMS'] = int(cp['prim-TOTAL_FORMS'])+ 1
    prims = PrimaryFunctionFormSet(cp,prefix='prim')

Then just spit the form out as normal. Keeps your data, adds an inline editor.
