Solve the problem that one form corresponds to multiple buttons in Django

Requirements:

In django, sometimes we need to set multiple buttons in a form to achieve different functions.

Solution:

Add different name attributes for different buttons, and then judge the name value in the background. python2 environment, for example:

Our form header

<form method="post" action=" Custom "  O nsubmit="return">

Our buttons, such as deleting and updating

<button type="submit" class="btn btn-info" name="del"> Delete </button>
<button type="submit" class="btn btn-info" name="update"> Update </button>

Then different functions are realized through different name

def function(request):
  if request.POST:
    if request.POST.has_key('update'):
      ...   #update Function realization 
    else:
      ...   #del Function realization 
    return render(request, 'xxx.html', yyy)

That is, according to has_key (), judge different buttons and then realize different functions.

In python3, the has_key () method is deleted and replaced with in, as follows:

if 'update' in request.POST:
