Multiple Models in Django-filter 1.1.0
I'd like to implement a filter for the end user of the site, so that they can filter by price, rating, gender and location. The problem here is that price and rating are stored in the models class "comment" and the location and gender in the models class "adventure". In the class "comment" the "adventure" is referenced by a foreign key. How can I use Django-filter 1.1.0 in my filters.py to address both models "comment" and "adventure" that reference each other, to filter according to the above mentioned arguments? Here is my code that works, but only filters the class "adventure". How can I extend this code to also filter by the foreign referenced arguments to return the matching adventures? filters.py import django_filters class AdventureFilter(django_filters.FilterSet): class Meta: model = Adventure fields = { 'gender', 'location', } models.py class Comment(models.Model): verfasser = models.ForeignKey(User, on_delete=models.CASCADE) related_adventure = models.ForeignKey(Adventure, on_delete=models.CASCADE, related_name='comments') rating_choices = ( (1, '1 Stern'), (2, '2 Sterne'), (3, '3 Sterne'), (4, '4 Sterne'), (5, '5 Sterne') ) Rating = models.PositiveIntegerField(null=True, choices=rating_choices,blank=False, default=0) verfasst_am = models.DateTimeField(default=timezone.now, blank=True, null=True) heading = models.CharField(max_length=100,blank=True,null=True, help_text="100 Zeichen") ratingtext= models.TextField(max_length=400, blank=True, null=True,help_text="400 Zeichen") price = models.PositiveIntegerField(null=True, help_text="Deine Ausgaben (pro Kopf) bei diesem Adventure", blank=True) class Adventure(models.Model): … -

Django Admin multiple template inheritance
I thought it was a quite simple task but turns out it's not. So, I have two different mixins to use on a Django admin class. they both have some codes in it with templates. admin.py class AdminMixin01(admin.ModelAdmin): change_form_template = "change_form1.html" class AdminMixin02(admin.ModelAdmin): change_form_template = "change_form2.html" class ModalAdmin(AdminMixin01, AdminMixin02, admin.ModelAdmin): pass change_form1.html {% extends "change_form.html" %} {% block content %} {{ block.super }} Form 1 {% endblock content %} change_form2.html {% extends "change_form.html" %} {% block content %} {{ block.super }} Form 2 {% endblock content %} it's looks quite simple both python and html sides. The problem is Django renders only first mixin's template and ignores the second mixin's template. In this case only change_form1.html rendered into original change_form.html template and no traces from change_form2.html. The python codes in the both mixin are working except html codes. Any ideas ? -

How to tag a comment with the blog post in django?
i am new to django and am currently working on the diy blog project to improve my understanding. I am trying to insert a comment form for my viewers using the CreateView template. Viewers will need to log in to type their comment. Their username will be tagged to the comment for the respective blog without them needing to indicate anything. However, i am only able to tag their comment with their username but not to the blog post. I am not sure why. Below is my code that is stored in the (view.py) class CommentCreate(LoginRequiredMixin,CreateView): model = Comment fields = ['comment','blog'] template_name = 'catalog/blog_comment.html' def get_context_data(self, **kwargs): context = super(CommentCreate, self).get_context_data(**kwargs) context['blog'] = get_object_or_404(Blog, pk = self.kwargs['pk']) return context def form_valid(self, form): form.instance.author = self.request.user return super(CommentCreate, self).form_valid(form) def get_success_url(self): return reverse('blog-detail', kwargs={'pk': self.kwargs['pk'],}) Any advice is appreciated. Thank you. -
Firebase FCM push notifications not show on iOS 12
I am using python 3 and Django framework with Firebase FCM to send push notifications from an iOS device. The push notifications did not show on device, until yesterday. When I now send a push notification, everything shows successful, but nothing is received on the device. If I send directly via a curl request, this is the response: {'failure': 0, 'canonical_ids': 0, 'success': 1, 'multicast_ids': [8348728835412078810], 'topic_message_id': None, 'results': [{'message_id': '0:1543820637538874%6467bacd6467abcd'}]} If I send from the Notification dashboard on the firebase console, it shows successfully completed. I have done the following with no success: Locked in pod for, 'Firebase/Core' and 'Firebase/Messaging'. Generated a new APN key on developer console and replaced the existing key on FCM setup in Firebase. Downloaded a fresh GoogleService-Info.plist and replaced existing Checked that bundle id's etc all match. Updated firebase pods to latest versions Turned message swizzling off in info.plist file (i.e. FirebaseAppDelegateProxyEnabled = No) Setting Messaging.messaging().shouldEstablishDirectChannel = true Made sure remote notification in Capabilities are still turned on
