using re.sub for a substring which is stripped from spaces to convert it into html tags
My code aims to find substrings which start by hash sign, check whether they exist in database, and if so convert them into tags. Basically I want users to be able to referance to titles in their entries. The code is: def prettytext(content): c = content if "#" not in content and "@" not in content and "|" not in content: c={"content":content,"safe":0} return c else: if not bool(BeautifulSoup(content,"html.parser").find()): if "#" in content: baslik= re.findall(r"[#]([^#@$\\|]*)(?=[#@$\\|]|$)", content) baslik= list(set(baslik)) baslik.sort(key=len,reverse=True) for i in baslik: try: title= Title.objects.get(title = i) c = re.sub("[#]({})(?=[#@$\\|]|$)".format(i,),"<a class='title-link' href='/titles/{}--{}'>{} </a> ".format(i,title.id,i),c) print(c) except: if " " in i: j = i.rstrip() try: c = re.sub("[#]('{}')(?=[#@$\\|]|$)".format(i,),"<a class='title-link' href='/titles/{}--{}'>{} </a> ".format(j,title.id,i),c) except: pass Let's say my database has the value "title5" and the string is "#title5 #title5" the result is: print(prettytext("#title5 #title5")) {'content': "#title5 <a class='title-link' href='/titles/title5--5'>title5 </a> ", 'safe': 1} but it is supposed to be: {'content': "<a class='title-link' href='/titles/title5--5'>title5 </a> <a class='title-link' href='/titles/title5--5'>title5 </a> ", 'safe': 1} So at first, the code gets all the substrings as a set then sorts them by length from longest to shortest and it starts to check them. The reason why I wanted it to be sorted is because one substring … -

I was unable to combine 2 query_set of same model without apply ordering in Django?
I was working on a project and I came across a problem. I need a query_set which should have ordering according to created date but there are some items in the query_set which I need to place at the end of the query_set at all times. I don't need to apply ordering for those items. Those items should be always at the end of the query_set Here is my model class Bookings(model.Model): booking_title = models.CharField('Booking title', max_length=125, blank=True, null=True) user = models.ForeignKey(User, related_name='request_user', on_delete=models.CASCADE) practice = models.BooleanField(default=False) status = models.IntegerField(choices=[1, 2], default=1) created_date = models.DateTimeField(auto_now_add=True) Here is my query_set query_set = Bookings.objects.filter(status=1) Here is my solution (Which is don't work) query_set_practice = query_set.filter(practice=True) query_set_normal = query_set.filter(practice=False).order_by('created_date') query_set = query_set_normal | query_set_practice I need normal bookings first and practice bookings. The normal bookings should be in the order (last should be first). I need an optimized solution without adding any loops and multiple query_set creations. Please help me. -

Setting a new user inactive based on group -- Django
I am currently busy with my user app and trying to achieve a way to add new users to different pre-defined groups. My sign_up view for one of the groups is as follows: def signup_view_zakelijk(request): if request.method == 'POST': form = UserCreationForm(request.POST) if form.is_valid(): user = form.save() group = Group.objects.get(name='zakelijk') user.groups.add(group) return redirect('user:login') return render(request, 'user/signup.html', {'form': form}) else: form = UserCreationForm() return render(request, 'user/signup.html', {'form': form}) The group is assigned after the save form.save so i made a post_save signal: @receiver(post_save, sender=User) def user_zakelijk_inactive(sender, instance, **kwargs): group = Group.objects.values_list('name', flat=True) print(group) if group == 'zakelijk': if instance._state.adding is True: instance.is_active = False else: return else: return I've set the print statement to check if the user group names got printed and this works. But the new added user is not inactive by default. When I erase the if group == 'zakelijk' conditional the signal works properly but is also executed for other user groups (so every new user is inactive by default - only need this for the group 'zakelijk'. The Signal code that works properly: @receiver(pre_save, sender=User) def user_zakelijk_inactive(sender, instance, **kwargs): if instance._state.adding is True: instance.is_active = False else: return Does anyone have some ideas to addin the … -

How to mimic upload_to function in models with ordinary form
Hi I'm having this models, forms, views, settings let say models.py class ProfileModel(models.Model): user = Foreignkey(get_user_model()...) first_name = forms.CharField(....) # some attrs photo = models.ImageField(uploads_to='uploads/%Y/%m/%d', ...) forms.py class ProfileForm(forms.Form): first_name = forms.CharField() photo = forms.ImageField() def handle(self, request, *args, **kwargs): data = self.cleaned_data # update the profile model Profile.objects.filter(user__exact=request.user, **data) views.py def update_profile(request): if request.method == 'POST': form = forms.ProfileForm(request.DATA, request.FILES) if form.is_valid(): # update here via handle of form form.handle(request, *args, **kwargs) else: #... something settings.py MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' Please bare with me its a hybrid or bizzare in any case. The idea here is just use a form to update a model (not a modelform). via admin, upload_to seems to work e.g upload a picture, url = /media/uploads/..../photo when its comes to my form it just recognizes /media/ but not the upload_to, [btw its working its just that its behavior] e.g upload a picture, url = /media/photo it seems its not triggering the upload_to, I know the benefit of the modelform but in this case, is there a way? so anyone can help me much appreciated. Thank you for the help. -
Make Django and ReactJS friends. Authorization. Routing
I'm developing a Shopify App. I'm using Django for backend and React for frontend. I chose React because I want to use React Shopify Polaris components. I want to be able to have different pages (Settings, Dashboard, Statistics and so on). On the pages, I want to display some information retrieved from the server and processed by React. I don't know how to make them work together. I've seen a tutorials where people use React and Redux for all the logic and routing, Django-Rest-Framework for the server. I wanted to do the same. I faced the problem of authorization. It's done now with Django this way: https://github.com/Shopify/shopify_django_app/blob/master/shopify_app/views.py As a result, we have access_token variable inside request.session. We can check if user added the shop by the presence of this variable. Also after this process, we have our shopify.Shopify.session set. I don't know how to work this out with React. How to check in React if user added the shop (if is authenticated)? How to manage routing correctly? Which way do I have to use Django-React pair to achieve my goal? Maybe there are other ways of using Django and React together. -

DRF Methodserializer : Object of type <XXX>is not JSON serializable
i am trying to convert my existing project to the DRF . However im facing the error of : : Object of type TransitionApproval is not JSON serializable TransitionApproval object comees from a package called django-river. Here is my code: class ProjectDetailSerializer(serializers.ModelSerializer): requirements = CustomerRequirementSerializer(many=True) transitionApproval = serializers.SerializerMethodField('get_transition_approval') class Meta: model = Project fields = '__all__' depth = 2 def get_transition_approval(self,project): transitions = TransitionApproval.objects.filter(object_id=project.pk).filter(workflow__field_name='project_status') print(transitions) return transitions My console prints : <CTEQuerySet [<TransitionApproval: TransitionApproval object (1)>, <TransitionApproval: TransitionApproval object (2)>, <TransitionApproval: TransitionApproval object (3)>]> Is there a good way to solve this? I have tried doing this : class ProjectDetailSerializer(serializers.ModelSerializer): requirements = CustomerRequirementSerializer(many=True) transitionApproval = TransitionSerializer(many=True) class Meta: model = Project fields = '__all__' depth = 2 but it seems that 'transitionApproval' is not an attribute of Project. Im not sure how to resolve this.
