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>
