how to set filefield's url

Using Django
1

i use new FormData() in js instead of form in html,so “upload_to” in FileField not works anymore.
and the file’s url is right when server in localhost,but not right in remote server.
in remote server the url looks like this:
http://192.168.1.106:8001/media/home/evehal/unilawer/media/m_1as.jpg
it should be:
http://192.168.1.106:8001/media/m_1as.jpg
so,how to fix it?

here is upload code:

def upload_file(file):
    if file is not None:
        import os
        dir_path = settings.MEDIA_ROOT
        (filename, extension) = os.path.splitext(file.name)
        filename += '_' + uuid.uuid4().hex
        filename += extension
        if not os.path.exists(dir_path):
            os.makedirs(dir_path)
        file_path = os.path.join(dir_path, filename)
        with open(file_path, 'wb') as f:
            for chunk in file.chunks():
                f.write(chunk)
        return file_path

You should return the [media_url] (http s://docs.djangoproject.com/en/3.0/ref/settings/#media-url) instead of the [media_root] (http s://docs.djangoproject.com/en/3.0/ref/settings/#media-root).

I am not sure what your use case is - but you could look at [File_Field] (http s://docs.djangoproject.com/en/3.0/ref/models/fields/#filefield) which might provide the functionality that you might want to use. If its not quite what you want you can look at the [source] (http s://github.com/django/django/blob/f600e3fad6e92d9fe1ad8b351dc8446415f24345/django/db/models/fields/files.py) of the field and get an Idea how it is managed internally.

A good explanation on the broad topic would be [Managing Files] (http s://docs.djangoproject.com/en/3.0/topics/files/)

If all this didn’t help - please explain the thing that you are trying to accomplish a bit further, I might just didn’t catch it right.
