Django - 如何在视图中更改窗体的占位符

Question

如何在视图中更改表单的占位符？

def myview(request):
    form = MyForm()
    form.widget.attrs.placeholder = 'Replace placeholder value'

Answer 1

您可以动态设置占位符到表单字段：

def someview(request):
    form = SomeForm(..)

    if some_condition:
        form.fields['yourfield'].widget.attrs['placeholder'] = instance.yourfield
