Serializing the Django object in the required format
I have a Storage model in which I get objects using serialization: tree_data = serializers.serialize ("json", Storage.objects.all ()) It looks like this: [ {"model": "hello_extjs.storage", "pk": 9, "fields": {"code": "000", "name": "Title 1", "id_parent": 0}}, {"model": "hello_extjs.storage", "pk": 10, "fields": {"code": "111", "name": "Test 1", "id_parent": 9}}, {"model": "hello_extjs.storage", "pk": 11, "fields": {"code": "222", "name": "Test 2", "id_parent": 9}}, {"model": "hello_extjs.storage", "pk": 12, "fields": {"code": "333", "name": "Title 2", "id_parent": 0}}, {"model": "hello_extjs.storage", "pk": 13, "fields": {"code": "444", "name": "Test 3", "id_parent": 12}}, {"model": "hello_extjs.storage", "pk": 14, "fields": {"code": "555", "name": "Test 4", "id_parent": 12}} ] I need to have the data in this form: { text: 'Storage', expanded: true, children: [{ text: "Title 1", children: [{ text: "Test 1", leaf: true }, { text: "Test 2", leaf: true }], leaf: false, "expanded": true }, { text: "Title 2", children: [{ text: "Test 3", leaf: true }, { text: "Test 4", leaf: true }], leaf: false, "expanded": true } ] } How should I serialize objects to get the data in the form in which I need it? -

Django USE_L10N with JQuery DateRangePicker
I'm trying to use the JQuery DateRangePicker in my Django Forms. I enabled the USE_L10N=True option in my settings.py to allow Django to automatically detect the Date Format according to the user localization. Anyways, even if the DateRangePicker plugin allows me to choose the locale format, it doesn't detect it automatically like Django does, so I'm not able to match the two date formats. Which is the best practice? Django doesn't change the date format according to the website language, so I can't use the language code to change the JQuery plugin format. Maybe should I ask Django the current country code? Is it possibile? Thank you -
(2002, "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)")
I am on mac with homebrew mysql, making a django app. I also use jupyter. I don't know which of these things is the root cause of the issue. I used to get this error message coming up every now and again, and I know how to fix it: just type brew services restart mysql and wait a bit. The problem is that it's now happening with increasing frequency, several times an hour. Is there a known fix for this, when working on a local machine? I thought, since I'm ctrl-c ing programs frequently, that might be exhausting the connection pool so I increased the connection pool size using SET GLOBAL max_connections = 5000;, but that has not helped. -

Action when a foreign key is being changed on django
The question in general is about finding the modification of a foreign key of a model and call some function of the related model. Assume I have two model class: class Discount(models.Model): def use(self, sell_item): if self.max_price: self.max_price -= sell_item.net() if self.max_count: self.max_count -= sell_item.amount self.save() def deuse(self, sell_item): if self.max_price: self.max_price += sell_item.net() if self.max_count: self.max_count += sell_item.amount self.save() max_price = models.PositiveIntegerField(blank=True, null=True) max_count = models.PositiveIntegerField(blank=True, null=True) amount = models.PositiveIntegerField(blank=False, null=False) class SellItem(models.Model): def net(self): price = self.amount * self.price if self.discount: price -= self.discount.amount * price / 100 return price * (1 + self.tax / 100) amount = models.PositiveIntegerField(balnk=False, null=False) price = models.PositiveIntegerField(blank=False, null=False) tax = models.PositiveIntegerFeidl(blank=False, null=False) discount = models.ForeignKey(Discount, blank=True, null=True) Now I want to execute use function whenever a discount add to an item and deuse it whenever it is being removed from an item.

Django: displaying different navbar options depending on if the user has created a userprofile or not?
I have a question on how can I display different options for navbar depeding on if the user has created a userprofile or not. I have tried many options including {% if profiles_list %} as well as {% ifequal user userprofiles.objects.all %} on base.html as well as creating a simple tag on templatetags but it does not seem to work. I have also tried changing views but since I am relatively new to coding I prefer to play around with "base.html". However, any suggestion will be welcomed. I want options to display in a way where if a user has not created a profile then only options of search, messages, about us and create new profile will appear. And if they have created a profile, then create new profile will be replaced with Edit profile, and further options of Delete profile and View Profile will also appear. My code is as below: base.html <div class="container"> <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="{% url 'home:index' %}"> <img src="{% static "images/rainbow.jpg" %}" width="100" height="100" alt=""></a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarNav"> <ul class="navbar-nav"> {% if user.is_authenticated %} <li class="nav-item active"> <a … -

How can I manually edit a specific attribute in a model through Django Shell?
I recently added a created_by attribute in Store model. Since this automatically gets a current logged in user when a store is created, if I don't manually assign any user, that column will be forever null. class Store(models.Model): ... created_by = ForeignKey(settings.AUTH_USER_MODEL, related_name='stores_of_created_by', null=True, blank=True) So, I want to assign a user manually. I think Django Shell (something that can be triggered through python manage.py shell) would be a good way to assign users manually. I'm very confused how I can manually assign a user in a specific attribute of all stores. So far I got a specific user and all stores in the following way. from django.contrib.auth.models import User from boutique.models import Store stores = Store.objects.all() user = User.objects.get(username='admin@gmail.com') After that, I need to loop through all stores and assign the user in created_by of all stores. How can I do that in Django Shell? -

Django include template using Javascript
I came from a Rails background thus the question may seem stupid. In Rails, when we create a Ajax request, then we can update a view by rendering a partial using the javascript selector like the following: $("#dashboardEmails").html("<%=j render partial: 'emails', locals: {emails: @emails} %>"); How can I do that in Django template? I've tried the following: $.ajax({ type: frm.attr('method'), url: frm.attr('action'), data: frm.serialize() + "&submit=connect", success: function (data) { if(data['tables'].length > 0){ $('#data-connection-info').html("{% include 'projects/connection_info.html' with data='"data"' %}"); } console.log(data); }, error: function (data) { console.log("Error"); } }); Here, I want to update the view with a template projects/connection_info.html, also passing a javascript variable (data) to the template using with. But it is not working. Any idea how can I achieve that? -

check_password() returning False
I have made a model with its own password field. This is wholly separate from the User object. I'm using the django.contrib.auth.hashers library for this. In the create method for this model (overwriting a generic CreateListAPI view) def create(self, request, *args, **kwargs): data = request.data data['password'] = make_password(data['password']) serializer = self.get_serializer(data=data) serializer.is_valid(raise_exception=True) self.perform_create(serializer) headers = self.get_success_headers(serializer.data) return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) This stores a hashed password in my database as expected, but when I try to authenticate with the password def get_object(self): queryset = self.filter_queryset(self.get_queryset()) try: # Grabs the 'name' parameter from the URL obj = queryset.get(name=self.kwargs['name']) except Group.DoesNotExist: raise Http404 print(self.request.data['password']) # raw password string print(obj.password) # encoded password from database if check_password(self.request.data['password']), obj.password): raise Http404 obj.user_set.add(self.request.user) self.check_object_permissions(self.request, obj) return obj check_password returns False. However, passing in the encoded password as the raw string password works. So hashing the password works, but not comparing the raw password to it after the fact. -

Which JavaScript library/Framework (Reactjs/vuejs/Angular) Fits best with Django
Hello fellow developers, I was working on a Django project then I realized that the formal HTML templates have their own limitations. Then I started googling for a better frontend Which brings me too - Vuejs, ReactJs, Angular. No doubt all three of them are fantastic in their own way, But Which one works best with Django keeping in mind performance and scaling and rendering pages fast. Most of the tutorials on the internet are About Django+React some people claim that they are made for each other, But Just don't know why I don't like the way react works and it's syntax specifically maybe because I am from python background that's why. On the other hand, Angular looks way cleaner. Another great framework is VueJs but it lacks resources because it is not backed by companies like Google and Facebook. I can't be sure about its future. I am personally more biased towards Angular but we don't have many tutorials on Angular+Django But I hope installation won't be different for the react one like creating an API then providing the endpoints and run. I bet many of you have already worked with these great frameworks/library will you please share your … -
User authentication for Spotify API
I am creating a small project using Spotipy for the Spotify API. Through development I have been using localhost as the redirect and then copy and pasting the link that opens in the terminal. How do I properly handle this interaction so that I do not need to copy and paste links? Thank you very much! -

Django request.user becomes anonymous after changing page
I'm using a custom user model that extends BaseAbstractUser. This is the user model: class cUser(AbstractBaseUser): def save(self, *args, **kwargs): pass role_id = models.IntegerField() user_id = models.IntegerField() email = models.CharField(max_length=40) password = models.CharField(max_length=40) f_name = models.CharField(max_length=40) l_name = models.CharField(max_length=40) address_id = models.IntegerField() phone_num = models.IntegerField() loan_item_count = models.IntegerField() id = models.IntegerField(unique = True, primary_key = True) def __init__(self, dictionary, *args, **kwargs): self.role_id = int(dictionary['role_id']) self.user_id = dictionary['user_id'] self.email = dictionary['email'] self.password = dictionary['password'] self.f_name = dictionary['f_name'] self.l_name = dictionary['l_name'] self.address_id = dictionary['address_id'] self.phone_num = dictionary['phone_num'] self.loan_item_count = dictionary['loan_item_count'] self.id = self.user_id USERNAME_FIELD = 'user_id' class Meta: managed = False I don't want the model to affect the DB in any way. I'm loading it by a simple raw SQL query from a gateway method. This is how I'm handling login: def login_request(request): if request.method == 'POST': form = LoginForm(request.POST) if form.is_valid(): username = request.POST['username'] password = request.POST['password'] user = userGateway(username,password) if user is not None: print("=========USER==========") print(user.email) user.backend = 'django.contrib.auth.backends.ModelBackend' login(request,user) print(request.user.is_authenticated) if user.role_id==1: return render(request, 'biblioteca/admin/landing.html') # return HttpResponseRedirect('/') else: return render(request, 'biblioteca/landing.html') else: print("=========NOT USER==========") else: if(request.user is not None and not request.user.is_anonymous): return render(request, 'biblioteca/admin/landing.html') form = LoginForm() return render(request, 'biblioteca/login.html', {'form': form}) As you can see, … -
Postgresql Update Causes: 'django.db.utils.OperationalError: could not access file "$libdir/postgis-2.4": No such file or directory'
Our Django project running on an OSX instance is having an issue after a accidental upgrade with brew. Previously, the Django system was running postgresql-9.5 with postgis-2.3 and worked with no issues. However once brew installed postgresql version 10.5 and postgis 2.5 everything started to break. After this update we receive the following error when trying to run a database query in Django: django.db.utils.OperationalError: could not access file "$libdir/postgis-2.4": No such file or directory When going into psql to try and get the extenstion to 2.4 by running: ALTER EXTENSION postgis UPDATE TO "2.4.0"; We get the error: ERROR: extension "postgis" has no update path from version "2.5.0" to version "2.4.0" We have been unsuccessful in reinstalling postgresql 9.5 and postgis 2.3 with brew and are not sure where to turn next to try and get the development system running. Looking for suggestions on how to either get the Django instance to look for extension 2.5 which I'm guessing now exist or to return the postgres system to it's former state on the mac through brew. Django version 2.0.1 and psycopg2 version 2.7.3.2
