Django message recipient url
so i have django-messages installed on my website: https://github.com/arneb/django-messages and it states in the docs "Messages can be composed and there is an easy, url-based approach to preloading the compose-form with the recipient-user, which makes it extremly easy to put "send xyz a message" links on a profile-page." and I've found the url being , ^messages/ ^compose/(?P<recipient>[\w.@+-]+)/$ [name='messages_compose_to'] however the docs give no information on how to implement this, i would like to be able to add send user a message on the profile page of each user however being so new to django i dont really unserdtand how to implement this. Could someone please guide me in the right direction? i would really appreciate any help. Thank you, and sorry for being such a noob. Callum -
Dynamically create buttons or send data to buttons
I am dynamically trying to pass data that I get from my for loop to the buttons. I am using django to get the data in the for loop, html to make the button and jquery to pass the data. I am not sure if this is the best description though. My code is: {% for dogs in Dogs.Other %} <form id="primaryDogForm" action="{% url 'personal:account:email_dog_confirm' %}" method="post"> {% csrf_token %} <input type="hidden" id="dogId" name="dogId" value="{{ dogs }}"> <input type="button" value="Make this your primary dog" id="makePrimaryButton" class="btn btn-primary" data-toggle="modal" data-target="#makePrimary" /> </form> {% endfor %} Basically, people can add a list of dogs to their account and select a dog to be their primary dog. I want a modal to be called when I click on the button. And that modal should display the name of the dog that is potentially being made the primary dog. The modal code is as follows: <div class="modal fade" id="makePrimary" tabindex="-1" role="dialog" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> <h4 class="modal-title">Make Primary</h4> </div> <div class="modal-body"> <p> You are about to make <span id="newDog" name="newDog"></span> your primary dog. </p> <hr> <a href="#" id="makePrimarySubmit" class="btn btn-primary">Submit</a> </div> </div> … -
Django + Dropzone - I can't display files
I'm creating Django application with gallery. That gallery have albums and photos. Photos have foreign key to album. In template I'm sending files and album id (only one person can add something to gallery, so I don't have to worry about that as a security hole). I'm sending these files with dropzone's javascript. Then in view I use such code to save photos: if 'addphotos' in request.POST: if ('Album' in request.POST): ualbum = Album.objects.get(id=request.POST['Album']) print(ualbum.title)#just checking, this part works files = [request.FILES.get('dzfile[%d]' % i) for i in range(0, len(request.FILES))] for ufile in files: p = Photo.objects.create(album=ualbum, file=ufile) And something is not working there with files. Photo object is created but file is not attached to it. In ./manage.py shell I did something like this: >>> from main.models import Photo >>> from main.models import Album >>> album = Album.objects.get(id=8) >>> print (album.title) teraz zadziała >>> photos = Photo.objects.filter(album=album) >>> print(photos) <QuerySet [<Photo: Photo object>, <Photo: Photo object>, <Photo: Photo object>]> >>> for photo in photos: ... print(photo.album.title) ... teraz zadziała teraz zadziała teraz zadziała >>> for photo in photos: ... print(photo.file.url) ...

Djangocms users don't have permission to add or edit plugins
I have a website, currently running with Django==1.8.6 and Django-CMS 3.0.x (running through upgrades at the moment). My users can not edit any of the frontend plugins. At the moment I am sure that this is not only true for my custom made plugins, but for ones that come with Django-CMS as well. As a test I have made a new User with all rights and staff status (no superuser). But also this user can't edit or add plugins. For my search I have found this: https://github.com/divio/djangocms-text-ckeditor/issues/78 I also tested the solution given there as I am using ckeditor, but I don't have an entry for text, so this: sqlite3> select * from django_content_type where app_label = 'text'; id | name | app_label | model ----+------+-----------+------- 23 | text | text | text For results to sqlite3> select * from django_content_type where app_label = 'text'; sqlite3> I tried to figure out how to debug permission errors. I have also looked through auth_permission, but everything seems to be alright. Is there anyway to debug the permission process in order to find whats preventing my users from using the frontend editing? -
Django 1.11 - Password reset
I have an issue with a password modification form. I don't want to use the password reset function from Django. def view_password(request): if request.user.is_authenticated(): if request.method == 'POST': form = ChangePasswordForm(request.POST) if form.is_valid(): new_password = form.cleaned_data['new_password'] confirm_password = form.cleaned_data['confirm_password'] if new_password == confirm_password: strengh = new_password[0].isalpha() if all(c.isalpha() == strengh for c in new_password): messages.add_message(request, messages.INFO, 'Le mot de passe doit contenir au moins 8 charactères lettres et chiffres.') else: update = User.objects.get(id=request.user.id) update.set_password('new_password') update.save() messages.add_message(request, messages.INFO, 'Votre mot de passe a bien été changé.') else: messages.add_message(request, messages.INFO, 'La confirmation du mot de passe est incorrect.') else: messages.add_message(request, messages.INFO, 'Une erreur est survenue pendant la modification.') else: form = ChangePasswordForm() return render(request, 'password.html', locals()) else: from start.views import view_logon messages.add_message(request, messages.INFO, 'Vous devez être connecté pour accéder à cette page.') return redirect(view_logon) The form works well and the modification of the password is done. However, after looked at the database, it seems that the new password is not well hashed. Indeed when I try to login with the new password or the old password, it doesn't work. Thanks for your help. -
Javascript Alert On Successful Form Submission
I am currently using Django 1.9 and Braintree payments JS v3. What I want to be able to do is when the user submits the form successfully, have a Javascript alert() pop up. But the pop-up message will be contingent on what the back end Python returns... So like this: Submit the form Run the backend stuff Pop up the alert with a message dependent on what is returned by the Python backend When the alert is closed, refresh or redirect var client_token = "{{ request.session.braintree_client_token }}" var form = document.querySelector('#checkout-form'); var submit = document.querySelector('input[type="submit"]'); braintree.client.create({ authorization: client_token }, function (clientErr, clientInstance) { if (clientErr) { // for error loading client authorization if(alert('There was a form verification issue, reloading page on close.')){} else window.location.reload(); return; } braintree.hostedFields.create({ client: clientInstance, styles: { 'input': { 'font-size': '14px' }, 'input.invalid': { 'color': 'red' }, 'input.valid': { 'color': 'green' } }, fields: { number: { selector: '#card-number', placeholder: 'Credit Card Number' }, cvv: { selector: '#cvv', placeholder: '123' }, expirationDate: { selector: '#expiration-date', placeholder: '10/2019' }, postalCode: { selector: '#postal-code', placeholder: '10014' } } }, function (hostedFieldsErr, hostedFieldsInstance) { if (hostedFieldsErr) { // for errors creating form if(alert('There was a form creation issue, reloading … -

Python - logged exception is just '__exit__'
I am getting an internal server error for one of my view functions in Django that takes an image file and saves it to one of my models. The view function works in development, but is giving me an internal server error in production. I tried to wrap the part of the code that is failing in a try/except block, but the exception that it logs just says '__exit__' I'm not really sure what this means, or what kind of exception it is. I tried looking up what that exception would mean, but couldn't find anything. Does it have something to do with opening the file, and having issues closing it ? The exact part of the view function that breaks is where it says ... if name == 'one': trade_in.photo_one = file View def edit_photos(request): trade_in = account_trade_in(request) if not trade_in: return HttpResponse(json.dumps({'error': 'Something went wrong, unable to edit photos'}), content_type='application/json') if request.method == 'POST': try: file = request.FILES['file'] name = request.POST['photo'] if name == 'one': trade_in.photo_one = file elif name == 'two': trade_in.photo_two = file elif name == 'three': trade_in.photo_three = file elif name == 'four': trade_in.photo_four = file elif name == 'five': trade_in.photo_five = file elif name … -
Can I use a base64 encoded byte string as Django's secret key?
Is it acceptable to generate my SECRET_KEY in Django base64.base64encode(os.urandom(32)) or would using binascii.hexlify(os.urandom(32)) be a better option? If neither of these, what would you suggest? I'm trying to avoid Django's get_random_string since I don't think that is as secure. This is for a production environment. I could also increase the integer passed to os.urandom but I'm not sure what value is not overkill. -
Django messages automatically add username to recipient box
So i currently have django-messages on my website: https://github.com/arneb/django-messages and i have user profiles with an image, bio etc. I was wondering if there was a way to implement a button that would allow user when they are on another users profile to click a button and be able to send that person a message directly. So currently i could add a button that takes them to compose a message page, however they then need to manually add the persons username into Recipient*, as you can see in the image below. Ideally the persons username from the profile they where on would automatically be put into the recipient box. i would really appreciate any ideas, as i currently have no idea how to even start working on this.

Django App Config in application located inside folder

Django: filter by a property defined on a model, in a DRY way?
I'm working in Django 1.10. I have a model like this: class MyEvent(models.Model): class = models.ForeignKey(Class) starts = models.DateTimeField() url = models.URLField(blank=True, null=True) def in_past(self): return self.starts.date() < datetime.date.today() def is_interesting(self): return self.url or not self.in_past() In a couple of different places in my app, I want to show only events that are "interesting" as defined above, i.e. have a URL or aren't in the past. I want to display headers in the template if any such events exist. I don't seem to be able to do this in my views: events = MyEvent.objects.filter(is_interesting=False) in the view. In the template, I can filter individual events by this property, but I can't tell if there are any such events: {% if events.is_interesting.any %}Interesting events{% endif %} always returns false. Is there any way I can get a list of "interesting" events in my views or templates, in a DRY way? -
Create foreignkey object instances on parent create - Django

My guess would be that I need to define a custom init method inside the Req model class. If so, can I perform csv validation inside that as well? Will either class instance be created if the validation fails? I would prefer not to have the classes created, and I will redirect the user to try again. I am also using a generic create view at this point. Can I modify this view, or is it necessary to write a completely custom view? views.py class RequestCreate(CreateView): model = Request fields = ['name', 'upload'] success_url = reverse_lazy('requests:index') -

Django elif template tag rendering with constant
I'm trying to compare a dictionary value with a constant and I'm noticing these are being treated differently, based on whether I use an if/elif statement and if I just compare the value directly with the value stored in the constant.

Am I missing something here as to why option 1 doesn't work? view: STATUS1 = 1 STATUS2 = 2 STATUS3 = 3 context = { 'obj1': {'status': STATUS3, 'otherattrs': 'other stuff'}, 'STATUS1': STATUS1, 'STATUS2': STATUS2, 'STATUS3': STATUS3 } option 1 template: {% if obj1.status == STATUS1 %} button 1 {% elif obj1.status == STATUS2 %} button 2 {% elif obj1.status == STATUS3 %} button 3 {% endif %} option 2 template: {% if obj1.status == STATUS1 %} button 1 {% endif %} {% if obj1.status == STATUS2 %} button 2 {% endif %} {% if obj1.status == STATUS3 %} button 3 {% endif %} option 3 template: {% if obj1.status == 1 %} button 1 {% elif obj1.status == 2 %} button 2 {% elif obj1.status == 3 %} button 3 {% endif %}
