File upload with Django form

Question

I am trying to upload video files to vimeo, this is my code views.py

def upload_to_vimeo(request):
    token = 'xxxxx'
    if request.method == 'POST':
        video_file = request.POST.get("video_file")
        v = vimeo.VimeoClient(
            token=token,
        )
        video_uri = v.upload(video_file)
        print(video_uri)
        return redirect('home')
    return render(request, 'forms/video_upload_form.html', {})

template

                <form action="." method="POST" enctype="multipart/form-data">
                    {% csrf_token %}
                    <input type="file">
                    <input type="submit" class="button" value="Upload">
                </form>

but it throws error

AttributeError at /upload_to_vimeo/
'NoneType' object has no attribute 'read'

but I can directly upload without a form as follows

 v = vimeo.VimeoClient(
        token=token,
    )
    video_uri = v.upload('client_admin/test1.mp4')

How I can do it with a form, any help

Edit

Traceback:

During handling of the above exception (stat: path should be string, bytes, os.PathLike or integer, not NoneType), another exception occurred:

This is the error traceback and urls file is as follows

path('upload_to_vimeo/', upload_to_vimeo, name='upload_to_vimeo'),

@Biju, I guess that the user isn't uploading the file. Check my answer, and be sure to read through the docs for request.FILES — Safwan Samsudeen

There are lots of things wrong with your code. Do all of the following, and check whether it works

Views

You aren't doing validation, so if the video_file is None, the error you keep saying will come
You should get the file from request.FILES

def upload_to_vimeo(request):
    token = 'xxxxx'
    if request.method == 'POST':
        video_file = request.FILES.get("video_file") # Returns None if there is no file
        if not video_file: # If the user hasn't uploaded the file, 
            return redirect('some-error-page') # redirect to some error page or to the same page with an error message. Or do something else
        v = vimeo.VimeoClient(
            token=token,
        )
        video_uri = v.upload(video_file)
        return redirect('home')
    return render(request, 'forms/video_upload_form.html', {})

HTML

You aren't setting the name attribute to the file.
I'm not sure about this, but I don't think you are supposed to put a dot in the action attribute (correct me in the comments if I'm wrong). Setting the action attribute to a blank string will POST it to the same page.

<form action="" method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="file" name="video_file">
    <input type="submit" class="button" value="Upload">
</form>

thanks for your answer, even if i change to request.files the error is same, my doubt is it actually a post request?

From what I can see you're omitting the name attribute for your file input field, hence request.POST.get("video_file") returns none.

Add name to your file input field name="video_file"

<form action="" method="POST" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="file" name="video_file">
    <input type="submit" class="button" value="Upload">
</form>

UPDATE

update your view

video_file = request.FILES['video_file']

@crazychukz, it is a valid point, but still the error is there, 'NoneType' object has no attribute 'read'

crazychukz Over a year ago

@Biju I have updated the answer. It should get the file now. I tested locally myself

Biju Over a year ago

now it throws another error Exception Type: AttributeError at /upload_to_vimeo/ Exception Value: 'TypeError' object has no attribute 'message'

crazychukz Over a year ago

@Biju from the code you've so far I can't see what could be causing this new error... I can't see any reference to the message variable or where you tried accessing it
