class UserProfile(models.Model):
    user = models.OneToOneField(User)
    bio = models.CharField(max_length=120, blank=True,  verbose_name='Biography')
    follows = models.ManyToManyField('self', related_name='followers', symmetrical=False, blank=True)
    theme = models.ImageField(upload_to=get_image_path, blank=True)

    def __str__(self):
        return self.bio

class Tweet(models.Model):

    tweets = models.TextField(max_length=120)
    date = models.DateTimeField()


    def __str__(self):

推荐答案

您可以在GET或POST上执行此操作。这是GET的观点,因为这更简单。

You could do this on a GET or a POST. Here's the view it on a GET since that's simpler.

from django.http import JsonResponse
def follow_user(request, user_profile_id):
    profile_to_follow = get_object_or_404(UserProfile, pk=user_profile_id)
    user_profile = request.user.userprofile
    data = {}
    if profile_to_follow.follows.filter(id=user_profile.id).exists():
        data['message'] = "You are already following this user."
    else:
        profile_to_follow.follows.add(user_profile)
        data['message'] = "You are now following {}".format(profile_to_follow)
    return JsonResponse(data, safe=False)

然后在您的urls.py中,您需要将以下内容添加到urlpatterns。

Then in your urls.py you'd need to add the following to your urlpatterns.

url(r'^follow/(?<user_profile_id>[\d]+)/$', views.follow_user)

然后,您需要使用以下JavaScript:

Then you'd need to use some javascript like the following:

$('.follow-button').click(function() {
    $.get($(this).data('url'), function(response) {
        $('.message-section').text(response.message).show();
    });
});

这假设一些html如下:

This assumes some html like the following:

<body>
    <div class="message-section" style="display:none;"></div>
    {% for user_profile in all_user_profiles %}
        <button data-url="{% url "example_app.views.follow_user" user_profile_id=user_profile.id %}"
                class="follow-button" type="button">Follow</button>
    {% endfor %}
</body>
