flask - flask 管理表单编辑规则导致“没有字段”错误

Question

在我的类RequestView（ModelView）中：我有...

form_edit_rules = (
    rules.FieldSet(('name', 'email', 'phone','shopname', 'invoice', 'territory'), 'Customer Information'),
    rules.FieldSet(('address', 'address2', 'city','state','zipcode'), 'Shipping Information'),
    rules.FieldSet(('carrier','num_labels','shipping_label_url', 'shipping_tracking_num', 'shipping_label_url_2', 'shipping_tracking_num_2', 'shipping_label_url_3', 'shipping_tracking_num_3', 'shipping_label_url_4', 'shipping_tracking_num_4'), 'Shipping Labels / Tracking'),
    rules.FieldSet(('created','reason', 'status', 'sales_attention_comments', 'message', 'customer_notes','salesperson'), 'Return Information'),
    rules.FieldSet(('pdffile','credit','audit_reason', 'audit_detail','light_plan','shipping_territory', 'notes','completed'), 'Auditor Fields')
    )

出于某种原因，包含“电话”会使它丢掉并导致此错误：

ValueError：0x11007bc88处的Form flask_admin.contrib.sqla.form.RequestForm对象没有现场电话

如果我删除手机，它就可以正常工作。

我在模型中声明了以下电话：

phone = db.Column(PhoneNumberType())

请注意，我有一个自定义的前端表单，可以将数据保存到电话字段中。只有管​​理员编辑表单的此修改才会引发错误。

Answer 1

可能由于PhoneNumberType字段的复杂性，flask-admin不知道如何呈现其小部件，因此表单上缺少该小部件。

尝试将其作为StringField与form_extra_fields一起添加到form_edit_rules中，如下所示：

from wtforms.fields import StringField

class RequestView(ModelView):
    form_extra_fields = {
        'phone': StringField('phone')
    }
    form_edit_rules = (
        rules.FieldSet(('name', 'email', 'phone','shopname', 'invoice', 'territory'), 'Customer Information'),
        rules.FieldSet(('address', 'address2', 'city','state','zipcode'), 'Shipping Information'),
        rules.FieldSet(('carrier','num_labels','shipping_label_url', 'shipping_tracking_num', 'shipping_label_url_2', 'shipping_tracking_num_2', 'shipping_label_url_3', 'shipping_tracking_num_3', 'shipping_label_url_4', 'shipping_tracking_num_4'), 'Shipping Labels / Tracking'),
        rules.FieldSet(('created','reason', 'status', 'sales_attention_comments', 'message', 'customer_notes','salesperson'), 'Return Information'),
        rules.FieldSet(('pdffile','credit','audit_reason', 'audit_detail','light_plan','shipping_territory', 'notes','completed'), 'Auditor Fields')
    )

电话字段的验证已保留，因此我想它将解决您的问题。
