Post form data then render new template
So I have a form in my HTML that looks like this: <form id="passer" method="POST" action="{% url 'Sizer:printView' %}"> {% csrf_token %} <input type="hidden" id="vals"> <input type="submit" value="Print all selected items" id="printBut"> </form> With this form what I wish to achieve is when the submit button is clicked my jQuery will calculate a value and put it into the vals field in the form, then I want it to post to the printView view (to get the calculated data into a view) then once the data has been post render a new template and pass in the data calculated by the jQuery. My printView (where the data is being posted) looks like this: def printView(request): to_print = str(request.POST.get('vals')) template = "Sizer/printview.html" context = {'to_print':to_print} return redirect('requested_print_data', to_print) And my requested_print_data view (where I want to render my new template) looks like this: def requested_print_data(request): all_data['to_print'] = #Dont know how to get my variable template = "Sizer/printdata.html" context = {'all_data':all_data} return render(request, template, context) So at the moment what happens is when the form is submit, the value is calculated and stored into the form, the URL will gain the extra part from where it's being posted (www.example.com/printables ---On Submit---> www.example.com/printables/printview/) … -

Django: correct way to display dynamic images from arbitrary path
In my django app there is a model with CharField "avatar", storing the filename of object's picture (different for each object). Pictures themselves are stored in certain directory on the same host, but not inside the app directory. Say, django app is in /home/djadmin/myapp and images are in /tmp/avatars. Objects and images are frequently added/updated/deleted via other process (basically, images are uploaded to my host by ftp). I need to show these images in django template. Say, if field "avatar" stores "123.jpg" than I have to show image from path /tmp/avatars/123.jpg. How can I display these images using "img" tag in django template? I guess addind /tmp/avatars to STATICFILES_DIRS is not an option, because my images are not 'static'. -

How dose soundcloud features divided in django apps
I have read a lot about the rule in django that an app should be focused, an app should do one thing and do it well so if we are talking about 3 main features in a website like sound cloud Album: which have many songs Song: only one song , it could be part of an album Play list: has an album or some songs how it would be divided into apps in django should each one have it's own app with it's own models file and use each app in the other as the have relations -

Using ws4redis with Channels installed
We need to keep running ws4redis next to channels if we want to make the change, because we cannot guarantee everyone updates their mobile app that uses websockets. I succeeded in the configuration of Ngnix, Supervisor and Django for sockets through asgi and our old way of serving through wsgi runs alongside just fine. It's just that I can't get ws4redis to work. It seems like because it still uses a runserver command instead of calling uwsgi directly the process gets highjacked by Daphne and it fails. Now I don't know if I should file an issue at Channels, ws4redis or somewhere else. Maybe someone here knows how to proceed. supervisor config: [program:platform_production_uwsgi-main] command=/srv/platform/production/env/bin/uwsgi --ini=/etc/platform-serverconf/website.com/production/uwsgi-main.ini [program:platform_production_uwsgi-websockets] command=/srv/platform/production/env/bin/uwsgi --ini=/etc/platform-serverconf/website.com/production/uwsgi-websockets.ini [program:platform_asgi_daphne] directory=/srv/platform/production/src/ command=/srv/platform/production/env/bin/daphne -u /srv/platform/production/daphne.sock asgi:channel_layer [program:platform_asgi_workers] command=/srv/platform/production/env/bin/python /srv/platform/production/src/manage.py runworker process_name=asgi_worker%(process_num)s numprocs=4 ws4redis ini: [uwsgi] socket = /srv/platform/production/uwsgi-websockets.sock chmod-socket = 770 uid = deploy gid = www-data vacuum = true master = true single-interpreter = false enable-threads = true home = /srv/platform/production/env/ chdir = /srv/platform/production/src/ module = wsgi:_websocket_app touch-reload = /srv/platform/production/src/wsgi.py limit-as = 2047 logto = /srv/platform/production/logs/uwsgi-websockets.log logfile-chown = deploy:deploy buffer-size = 32768 cheaper = 5 cheaper-initial = 5 workers = 10000 cheaper-step = 2 uwsgi-websockets traceback: Traceback (most recent call last): … -

Regexfield insufficient to validate text input (Django form)
In a Django form, users set their usernames. The username field in the form is defined like so: username = forms.RegexField(max_length=50,regex=r'^[\w.@ +-]+$', help_text=_("Required. 50 characters or fewer. Letters, digits and " "@/./+/-/_ only."), error_messages={ 'invalid': _("This value may contain only letters, numbers and " "@/./+/-/_ characters.")}) Validation occurs when the regular expression is matched, otherwise not. For instance, setting the username Bender* is invalid, whereby Bender@ is valid. I've noticed that my form throws a nasty error if the user enters arabic or persian text, instead of elegantly invalidating it. E.g. if one tries العربی as the username, the following is thrown: UnicodeEncodeError at /keep_username/ 'ascii' codec can't encode characters in position 0-5: ordinal not in range(128) Why doesn't this piece of text invalidate like normally (and What can I do to fix this)? Thanks in advance! -
Storing billions of IPv6 with Django
I've faced the problem to track usage of IPv6 in our network. Currently Django have GenericIPAddressField that handles both IPv4 and IPv6 addresses and stores them as CHAR(39) in MySQL. For some time it was enough for our needs to process IPv4 and IPv6 the same way. BUT, now we have clients with hundreds of thousands of allocated IPv6 and with potential billions of IPv6 there must be completely different approach to store. I even think we must store them separately and not in MySQL. What is the proven way to deal with billions of objects (not only IPv6)? -

Django: uploaded files lost when using inline formset
I need to add a simple messaging feature to a Django 1.8 application. I have a Message model and the following Attachment model: class Attachment(models.Model): message = models.ForeignKey(Message) file = models.FileField() It should be possible for a user to create a message with multiple attachments using this formset: AttachmentFormset = inlineformset_factory(Message, Attachment, extra=1, exclude=[], can_delete=False) This is how all the forms are rendered in my template: <form action="" method="post"> {% csrf_token %} {{ msg_form.as_p }} {{ attachment_formset.management_form }} {% for form in attachment_formset.forms %} {{ form.as_p }} {% endfor %} <input class="button" type="submit" value="{% trans 'Send'%}"></input> </form> This is how I process the forms in my view: if request.method == "POST": msg_form = MessageForm(request.POST) attachment_formset = AttachmentFormset(request.POST, request.FILES) sender = request.user if msg_form.is_valid() and attachment_formset.is_valid(): msg = msg_form.save(sender=sender) for aform in attachment_formset: a = aform.save(commit=False) a.message = msg a.save() The problem is that somehow, request.FILES is always empty and the attachment form's cleaned_data is empty as well.

View being called twice/object created twice
I have a Comment model with 2 views: 1 for parent comment and one for replies. The parent view works fine but for some reason my reply view gets called twice, which creates 2 reply objects at once. So first off here's a .reply button the user clicks which brings up the comment form and giving that comment form an onclick value of reply_comment(): $('.reply').on('click', function(e) { var clone = $('.comment_form').clone(); parent_id = $(this).closest('.comment_div').data('comment_id'); $(this).closest('.comment_div').after( clone ); clone.addClass('reply_comment_form').removeClass('comment_form'); clone.attr('onclick', 'reply_comment()'); clone.data('comment_id', parent_id); $(this).next().css('display', 'inline-block'); $(this).css('display', 'none'); $('.reply_comment_form').css('padding', '1px'); }); And here's the actual function: function reply_comment() { $('.reply_comment_form').on('submit', function (e) { e.preventDefault(); parent_id = $('.reply_comment_form').data('comment_id'); $.ajax({ type: 'POST', url: '/comment_reply/', data: { reply_text: $(this).find('.comment_text').val(), parent_id: parent_id, id: path, csrfmiddlewaretoken: $("input[name='csrfmiddlewaretoken']").val(), }, success: function(data) { $('.reply_comment_form').replaceWith("<div class='comment_div new_comment'><div class='left_comment_div'>" + "<div class='username_and_votes'><h3><a href='#' class='username'>" + data.username + "</a></h3><span class='upvotes' style='margin: 0 6'>0</span><span class='downvotes'>0</span></div><br><p>" + data.reply_text + "</p></div><a href='#'><span class='comment_delete'>x</span></a></div>"); $('.new_comment').css({ 'width': '72%', 'margin': '0 70 10 0', 'float': 'right', }); $('.new_comment').next().css('clear', 'both'); $('.new_comment').prev().find('.cancel_comment').css('display', 'inline-block') .find('.cancel_comment').css('display', 'inline-block'); } }); }); } this AJAX call successfully appends the reply, and is sent to this view to save it to the database: def comment_reply(request): print('reply') if request.is_ajax(): comment = CommentForm(request.POST or None) reply_text = … -

Django Model Authorisation
In my django app, I've some CRUD opeaeations over some models, which I want to be accessed only by the user who created that row. Here its not role based authorisation as all users are same, I want them to be identified by the user who created it. I tried something like class someModel(models.Model): user = models.ForeignKey(User, db_index=True) .... In my views, I would do the checking by def view(request, id): model = somemodel.objects.get(id=id, user=request.user) if model.user = request.user: ... Would this be the easiest and yet be correct way to do row level authorisation? -
