我有一个表单，用户可以在其中动态添加字段。提交此表单时，后端只能看到后端生成的字段

#forms.py

class ExpensesForm(FlaskForm):
    expense_name = StringField('Expense_Item', validators=[DataRequired()])
    cost = FloatField('Cost', validators=[DataRequired()])
    due_date = DateField('Due Date', format='%Y-%m-%d', validators=[DataRequired()], default=datetime.datetime.today().date())
    type = SelectField('Role', choices=[('mutual', 'Mutual'),
                                        ('personal#1', 'Personal #1'),
                                        ('personal#2', 'Personal #2')
                                        ])

return render_template('index.html', form=form, ...)我正在通过从main.py到传递此表格 index.html

所有 4 个字段均通过以下方式生成：

<form class="form-horizontal" id="main-form" enctype=multipart/form-data role="form" method="post" action="/">
        <input type="hidden" name="count" value="1"/>
        {{ form.csrf_token }}

        {{ form.expense_name(placeholder="Expense Name", id="expense_1", value="") }}
        {{ form.cost(placeholder="Cost", id="cost_1", class="cost", value="") }}
        {{ form.due_date(id="due_date_1") }}
        {{ form.type(placeholder="Type", id="type_1") }}
        <button id="b1" class="btn btn-info add-more" …
