Hi,odoo Community:

    I have code in py:

MyFile = fields.Binary()

    And code in xml:

<field name="MyFile"/>

    Once I uploaded file through "MyFile",it display file name,but after I clicked "Save" button,then clicked "Edit" again,it 

lost file name and display “436Bytes”(my file's size),then I download the file,it names "NULL",so how should I change my

code to keep MyFile's name after saving and download the   original file?

   Thanks for your help!
