I've encountered a bug when using a binary field for storing a pdf, which I am not sure how to resolve.

Steps to reproduce:

Upload a file
Save
Use the edit button to upload another file over it
Save
Upload the edit button to upload again
Save and refresh the page
Observe

Expected result:

The third file is displayed/stored in the sale's order

Actual result:

The second file persists. Even deleting it, saving and then uploading a new file, still shows the second one on refresh.

Additional information
In my model, i've defined the field as follows

scanned_contract = fields.Binary(copy=False, help="Attach here the signed hard copy of the contract")

Then, in my view I display it like this, using pdf_viewer widget:

xpath expr="//field[@name='signature']" position="after"
	field widget="pdf_viewer" name="scanned_contract"/            
/xpath

Am I defining something wrong, or is this a bug with odoo/pdf_viewer itself?

Hi Daniel Bashev,

Here’s an example using Odoo's fields.Binary to upload a file with its filename stored separately. This can be useful in forms for handling file uploads, such as for importing data or documents.

Python:

class YourModel(models.Model):
    _name = 'your.model'

    import_file = fields.Binary('Select File')  # Binary field to store the file
    file_name = fields.Char('File Name')  # Char field to store the file name

XML (for the view):

Explanation:

import_file: This is the field where the file data is stored.
file_name: This field will store the name of the uploaded file. It is hidden (invisible="1") in the form but still recorded.
filename="file_name": This ensures the uploaded file is associated with its filename, which is automatically captured.

Let me know if you need further details or customizations!
