How to test a new user activation in Django?
I am trying to test django.contrib.auth-based user signup view with django-nose, where an activation link is being sent to a new user: def signup(request): if request.method == 'POST': user_form = SignUpForm(request.POST) profile_form = ProfileForm(request.POST) if user_form.is_valid() and profile_form.is_valid(): user = user_form.save(commit=False) user.is_active = False user.save() user.profile.user_type = profile_form['user_type'].data user.save() current_site = get_current_site(request) subject = 'activation email' message = render_to_string('registration/account_activation_email.html', { 'user': user, 'domain': current_site.domain, 'uid': urlsafe_base64_encode(force_bytes(user.pk)), 'token': account_activation_token.make_token(user), }) user.email_user(subject, message) return redirect('account_activation_sent') else: user_form = SignUpForm() profile_form = ProfileForm() return render(request, 'registration/signup.html', { 'user_form': user_form, 'profile_form': profile_form }) Currently I use Django built-in email back-end, so that activation email is being sent to the server terminal. I want to test the activation view which requires uid and token. Is there any way to access the email sent to the user? Is there any other way to test that? Regenerating token in the test does not work, because hash value is generated using timestamp. -

authentication Django on LDAP server
I would like my web application authenticate users on an ldap server (only for username and password), but that the permissions reside on django. Not all ldap users must have access to the web application. In particular, I would like to allow users to see only a few records (for example, suppose there is a model with a city field: some users should only be able to see records whose city field is london, others whose city is milano, etc.). How can i define django permissions if users are defined on ldap? How can I define the user's application admin if users are defined on ldap? Do I need to implement a double authentication? Do I have to define ldap users who can access the web application even on django? What is the best way to proceed? Do you have any suggestions? Examples? Thanks pacopyc -
Django dynamic HTML table refresh with AJAX
First of all, I am new with Django, and pretty much completely unfamiliar with AJAX and jQuery. So I'm trying to achieve a HTML table, that is dynamically refreshed every X amount of seconds with help from AJAX, but I can't seem to get my code to work. I've already used the example provided in this question: https://stackoverflow.com/a/34775420/6724882 (If I had enough rep, I would have either replied to that question, or asked help from chat, but I don't have that luxury yet) I've been trying to get this to work for 10+ hours, and I start to feel helpless. I've been searching the web like crazy, but I'm overwhelmed by all the different ways of doing this, and every question and answer seems to be either too many years old, or just not relevant to my app. So, I got couple questions. Should I include the script in its own separate file, and not in the HTML file (in my case, displaykala.html). If so, should that file be in the static/js folder, or somewhere else? Do I need to include AJAX/JS somewhere separately, in order for the script to work? Am I clearly doing something wrong, or is the … -

Broken django-debug-toolbar panels with sub domains configuration
I'm working on djangoproject.com website with Django Debug Toolbar configured in this dev settings. I founded an issue with django-debug-toolbar that I reported in the issue #796 of djanoproject.com but after some test I think it's only a configuration problem and we need help to solve it. All the below sentence are related with the code on branch master used locally. Django Debug Toolbar works well for www , for example, if I open http://www.djangoproject.dev:8000/ I can show the toolbar and open the SQL panel. If I try to open for example http://docs.djangoproject.dev:8000/en/1.11/ I can see the toolbar but I got 0: error if I try to open SQL panel This is the message I saw on browser console: Failed to load http://www.djangoproject.dev:8000/debug/render_panel/?store_id=212b2bb5adc54a3a81b97b6da5547d4c&panel_id=SQLPanel: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://docs.djangoproject.dev:8000' is therefore not allowed access.

Can you suggest to us how to change the dev settings to use django-debug-toolbar … -

get_thumbnailer renders different image than source image
I'm using get_thumbnailer from the sorl-thumbnail package and the cached image that is rendered in the key value store (used in conjunction with S3 storage pointing to a bucket) is different image than the source (ie: image = ImageField(upload_to='images')) My use case is that I have images being uploaded from camera on mobile via a HTML5 <input type="file" accept="image/*" capture="camera">. For each image, a thumbnail is being produced via the get_thumbnailer method. From desktop and android uploads I have no issues, but apparently on iOS the image upload and generation via the get_thumbnailer is not consistent, for some mysterious reason which I have yet to determine. The url attribute that get_thumbnailer renders from one of the uploads from an iOS is a different image than the source image. I don't expect answers, but if you can give me some idea then that's good enough. Just say something and I will give you an up-vote. -
