Hi forum!

I want to upload image from qweb into database and need to display in sales module. I don't know how to encode image before storing in database. Here is my code:-

<!-- Image Upload form -->
<form id="file_upload_form" t-attf-action="/website/form/" method="post" enctype="multipart/form-data" class="form-horizontal mt32">
<div class="row">
<div class="col-md-6">
<div>
<strong>Payment Screenshot</strong>
<input type="file" id="photo" name="photo" class="file" multiple="true" data-show-upload="true" data-show-caption="true" lass="file" data-show-preview="true" />
<button type="submit" name="screenshot" class="btn btn-primary">Upload</button>
</div>
</div>
</div>
</form>

<!-- Image Upload form -->

Here is my Api code which is placed in controller(main.py):-

# Check and insert values from the form on the model <model>
@http.route(['/website_form/'], method='POST', csrf=False, type='http', auth="public", website=True)
def upload_files(self, **post):
    values = {}
    for field_name, field_value in post.items():
        values[field_name] = field_value

    http.request.env['button.demo'].sudo().create({
        'image': values['photo'],
})

In database, Image is stored like this:- <FileStorage: 'temp.png' ('image/png')>

When I see that field in Sales module, it shows me 257 bytes and then I open this particular image it automatically remove from database
