如何在Django中登录用户ID

Question

I am very new in Python and Django. A am trying to make app but I have an issue. Can anyone help me, please xD I can't get id of authenticated user... I tried it in this way, and many other ways...

views.py

class CreateProfile(CreateView):
    template_name = 'layout/add_photo.html'
    model = Profile
    fields = ['image', 'user']

html

<form class="form-horizontal" action="" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    <input type="text" name="username"> #Here has to be field filled in with logged in user
    <input type="file" name="image"> 
    <div class="form-group">
        <div class="col-sm-offset-2 col-sm-10">
            <button type="submit" class="btn btn-success">Save Changes</button>
        </div>
    </div>
</form>

And when I'm starting app, and want to change/add picture, I can do it for anyone from my database, not only for logged in user. enter image description here

Thanks for patience and help!

In the Django ClassBasedViews you can get your user's id as self.request.user.id and in your template as {{ user.id }}

To check if someone is authenticated you can use self.request.user.is_authenticated() and in your template {% if user.is_authenticated %} .. {% endif %}

class CreateProfile(CreateView):
    template_name = 'layout/add_photo.html'
    model = Profile
    fields = ['image', 'user']

    # For example, if you want to return to a certain user
    # profile (which requires url adjustments to take a Primary Key)
    def get_success_url(self):
        user_id = self.request.user.id # Get user_id from request
        return reverse_lazy('git_project:user_profile', kwargs={'id': user_id})
