Question

search = True if (
        request.POST.get('name') or request.POST.get('city') or
        request.POST.get('email') or request.POST.get('tag') or
        request.POST.get('status') or
        request.POST.get('source') or
        request.POST.get('assigned_to')
    ) else False

我尝试了request.POST.get（'name'，..... etc）

但是它现在正在工作。我可以在一个地方分配全部吗？

Answer 1

你可以喜欢

inputs =  ['name','city','email','tag','status','source','assigned_to']    
search = inputs in request.POST.keys() #boolean

Answer 2

要检查所有存在的输入参数并具有值或满足其他要求：

// file_history_button
$('body').on('click', '.file_history_button', function (e) {
    const file_name = $(this).siblings().find('input').val();
    alert("file_name : ", file_name);
});

inputs = ['name','city','email','tag','status','source','assigned_to'] search = all (bool(request.POST.get(input)) for input in inputs)支票可以替换为任何其他必需的支票。

仅检查请求中是否存在必需的参数，而忽略它们的值：

bool()

或

inputs =  ['name', 'city', 'email', 'tag', 'status', 'source', 'assigned_to']
params = request.POST.keys()
search = all(input in params for input in inputs)

有没有一种简单的方法可以将所有输入集中在一行中？
