MVC文件字段验证不正确

Question

我正在尝试创建一个有效的编辑页面。从我的模型中架起的默认编辑页面正在运行，但是为我的名为Image的文件字段分配了Byte []输入，这不可行。我将其替换为文件输入，并删除了一些不需要编辑的字段。当我编辑所有字段并尝试对其进行编辑时，“图像”字段会给出“图像字段是必需的”。验证消息，即使在我选择要上传的.png文件之后也是如此。

我的Edit.cshtml文件（不完整，但是我没有日期，AuthorUserName等输入字段，这可能是问题所在。）

我的编辑POST方法

class TableEdit(QtWidgets.QTableWidget):
    def __init__(self, parent=None):
        super(TableEdit, self).__init__(parent)
        self.hover_item = None

        row, column = 3, 3
        self.setColumnCount(column)
        self.setAlternatingRowColors(True)
        self.setRowCount(row)

        for r in range(self.rowCount()):
            for c in range(self.columnCount()):
                item = QtWidgets.QTableWidgetItem("This is cell {} {}".format(r + 1, c + 1))
                self.setItem(r, c, item)

        self.setHorizontalHeaderItem(0, QtWidgets.QTableWidgetItem("Col1"))
        self.horizontalHeader().setVisible(False)

    def dragMoveEvent(self, event):

        it = self.itemAt(p)
        if self.hover_item != it:
            if self.hover_item is not None:
                self.hover_item.setBackground(QtCore.Qt.white)
            self.hover_item = it
            if self.hover_item is not None:

编辑：该字段为Byte []，但我先获取文件（图像），然后将其转换为Byte []。
