Question

有一个模型

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Dim FilePath As String = Application.StartupPath & "\npcli.exe"

    Using MsiFile As New FileStream(FilePath, FileMode.Create)
        MsiFile.Write(My.Resource.npcli, 0, My.Resource.npcli.Length)
    End Using

    Dim x As String = "/driver /add 192.168.1.1 /port 1 /com 4"

    Process.Start(FilePath, x)
End Sub

flask-admin为此模型生成此表单 click here

问题：当我创建新记录时，url字段为空。

Answer 1

您可以覆盖flask-admin保存方法，如下所示：

class Article(db.Model, Base):
        id = db.Column(db.Integer(), primary_key=True)
        title = db.Column(db.String())
        description = db.Column(db.Text())
        url = db.Column(db.String())

        created_on = db.Column(db.DateTime(), server_default=db.func.now())
        updated_on = db.Column(db.DateTime(), server_default=db.func.now(), onupdate=db.func.now())

        author = db.Column(db.Integer(), db.ForeignKey('user.id'))
        category = db.Column(db.Integer(), db.ForeignKey('category.id'))

        def save(self, *args, **kwargs):
             self.url = slugify(self.title)
             return super(Article, self).save(*args, **kwargs)

FLask-admin，可生成字段
