Upload files in Odoo web form

Question

I have a custom web form in odoo. I need to upload files. My controllers.py:

@http.route(['/test/'], type='http', auth="user", methods=['GET', 'POST'], website=True)
def upload_files(self, **post):
    values = {}
    form_vals = {}

              ...........

    if post.get('attachment',False):
        Attachments = request.registry['ir.attachment']
        name = post.get('attachment').filename      
        file = post.get('attachment')
        attachment_id = Attachments.create(request.cr, request.uid, {
            'name':name,
            'res_name': name,
            'type': 'binary',
            'res_model': 'project.issue',
            'res_id': form_id,
            'datas': base64.encode(file.read()),
        }, request.context)

            ............

Code above creates attachment, with name res_model etc., but attached file iss damaged and can't be opened.

XML file:

    ..........

<form t-attf-action="/test/done" method="post" enctype="multipart/form-data" class="form-horizontal mt32"><div t-attf-class="form-group">

    ..........

    <div t-attf-class="form-group">
        <label class="col-md-3 col-sm-4 control-label" for="attachment">Attachments</label>
        <div class="col-md-7 col-sm-8">
            <input name="attachment" type="file" class="file" multiple="true" data-show-upload="true" data-show-caption="true" lass="file" data-show-preview="true"/>
        </div>
    </div>>

    ..........
</form>

In console this:

name = post.get('attachments_for_issue').filename
_logger.error("name is: %r", name)
file = post.get('attachments_for_issue')
_logger.error("file is?: %r", file.read())

returns:

5092 ERROR HDHDHD openerp.addons.test.controllers.controllers: name is: u'test_image.jpg'
5092 ERROR HDHDHD openerp.addons.test.controllers.controllers: file is?: <FileStorage: u'test_image.jpg' ('image/jpeg')>

Try : enctype="multipart/form-data" To: "enctype="application/octet-stream" – Faceplate

This doesn't work. Windows doesn't show what kind of error in log file, but page keeps loading and that's all. – Quirinal

when a file not opened on python. You got EOF or header error(s). upload require right content header . You got a base64 object but i haven't any idea about of your saving procedure. – Faceplate

Can you show more to show the controller.py and the xml file for more people to reference? – Rorrys

Did this ever work for you ? I am trying exactly the same method but I get this error AttributeError: 'unicode' object has no attribute 'filename' – Sweetener

Answer 1

This is how it works:

file = post.get('attachment')
attach = file.stream
f = attach.getvalue()

and then:

...
'datas': base64.encodestring(f),
...

This adds file in attachment

This doesn't work. There's no object with a name "post". – Abuse

Answer 2

i think problem is with base64.encode(file.read())

from python docs we have
base64.encode(input, output)¶
Encode the contents of the input file and write the resulting base64 encoded data to the output file. input and output must either be file objects or objects that mimic the file object interface. input will be read until input.read() returns an empty string. encode() returns the encoded data plus a trailing newline character ('\n').

so, try to use in this way and check
attachment = file.read()
then
'datas' : attachment.encode('base64')

Lucrece

attachment = file.read() Returns nothing, so I guess problem is there. – Quirinal

Answer 3

If getvalue() doesn't work or gives issues like it gave me, you can also try:

file = post.get('attachment').stream.read()

then:

'datas': base64.encodestring(file)
