Get many to many fields changes in a post save in Django 1.11
So, I have a post_save signal in my code to save logs of changes in models, but the changes in many to many fields aren't applied at the point post_save is triggered, so changes in m2m fields aren't saved in my logs. My code (you can pretty much ignore the code inside the method): def save_log(sender, instance, created, raw, update_fields, **kwargs): if ( not hasattr(sender, '_meta') or sender._meta.label not in settings.MODELS_TO_BE_LOGGED ): return sensitive_fields = ['password', ] user = get_user() # This creates the log with a json describing the changes if created: # This method creates a log instance.save_addition(user, '') else: changed_field_labels = {} original_dict = instance.original_dict actual_dict = instance.to_dict( exclude=['created_at', 'updated_at', 'original_dict', 'id'], ) change = False for key in set(list(actual_dict.keys()) + list(original_dict.keys())): if original_dict.get(key) != actual_dict.get(key): change = True if key == sensitive_fields: changed_field_labels[key] = {'change': 'field updated'} else: changed_field_labels[key] = { 'from': original_dict.get(key, '-'), 'to': actual_dict.get(key, '-'), } if change: json_message = json.dumps( {'changed': {'fields': changed_field_labels}}, cls=ModelEncoder ) # This method creates a log instance.save_edition(user, json_message) For example, consider a model Event that has a many to many field to EventCategory called categories. If changes were made to an event through an UpdateView, for example (including … -
Using Django how can I render in a recursive python function before each return?
I am stuck on this. A function runs recursively changing objects each time. I want to render a updated view before every return. How can I render the template on every step of the python function recursive call? Or how can I approach this problem? Here is my function below: def solveBoard(box, board, size): if box.isFinalValue: newY = box.y newX = box.x + 1 if newX >= size: newX = 0 newY = newY + 1 if newY >= size: return True if solveBoard(board[newY][newX], board, size): return True return False else: allPossibleValues = getAllPossibleValues(box, board, 9) if not allPossibleValues: return False else: for i in allPossibleValues: board[box.y][box.x].numValue = i board[box.y][box.x].isEmpty = False newY = box.y newX = box.x + 1 if newX >= size: newX = 0 newY = newY + 1 if newY >= size: return True if solveBoard(board[newY][newX], board, size): return True board[box.y][box.x].numValue = 0 board[box.y][box.x].isEmpty = True return False -
least memory comsuming way of saving large python data into DB
I have to save a significantly large python data into the a mysql database which consists of lists and dictionaries (0.4MB) but I get memory exception during the save operation. I have already benchmarked the saving operation and also tried different ways of dumping the data, including binary format but all methods seemed to consume a lot of memory. Benchmarks below: PYTHON DATA SIZE: 0.4MB MAX MEMORY USAGE DURING JSON SAVE: 966.83MB SIZE AFTER DUMPING json: 81.03 MB pickle: 66.79 MB msgpack: 33.83 MB COMPRESSION TIME: json: 5.12s pickle: 11.17s msgpack: 0.27s DECOMPRESSION TIME: json: 2.57s pickle: 1.66s msgpack: 0.52s COMPRESSION MAX MEMORY USAGE: json dumping: 840.84MB pickle: 1373.30MB msgpack: 732.67MB DECOMPRESSION MAX MEMORY USAGE: json: 921.41MB pickle: 1481.25MB msgpack: 1006.12MB msgpack seems to be the most performant library but the decompression takes up a lot of memory too. I also tried hickle which is said to consume little memory but the final size ended up being 800MB. Does anyone have a suggestion? Should I just increase the memory limit? can mongodb handle the save operation with less memory? -
Ordering search results by date in Django
I'm trying to order the results of my search by the publication date, where the filter offers two choices: Order by lastest first or the most recent first. This is the filter that I've created so far to do that: filters.py class PubFilters(django_filters.FilterSet): CHOICES = ( ('Fecha', 'Más reciente'), ('Fecha', 'Menos reciente' ) ) ordering = django_filters.ChoiceFilter(label="Ordenar por", choices=CHOICES) class Meta: model = publicaciones fields = ['Precio', 'Categoría'] However, this returns "Cannot resolve keyword 'ordering' into field". And worse: Because I replaced the results for the filtered results (as you can see below), my pagination is suddenly broken, I can see the numbers but paginate_by isn't working. views.py class PostListView(ListView): model = publicaciones template_name = 'store/search.html' context_object_name = 'queryset' ordering = ['Promocionado'] paginate_by = 2 def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) MyFilter = PubFilters(self.request.GET, queryset=self.get_queryset()) context['filter'] = MyFilter context['filtered_items'] = MyFilter.qs context['count'] = self.get_queryset().count() context['búsqueda'] = self.request.GET.get('q') return context def get_queryset(self): qs = self.model.objects.all().order_by('id') search = self.request.GET.get('q') if search: qs = qs.filter(Título__icontains=search) return qs How could I show the filter for "ordering date" correctly? Thanks in advance! -
Django - Account Settings BooleanField
I reviewed most of the posts here related to Django and BooleanField update, but I couldn't find any related to my problem solution. I have a custom user models.py: # Own custom user model class Account(AbstractBaseUser): username = models.CharField(max_length=30, unique=True) guardianSource = models.BooleanField(default=True) bbcSource = models.BooleanField(default=False) independentSource = models.BooleanField(default=False) categoryCoronaVirus = models.BooleanField(default=False) categoryPolitics = models.BooleanField(default=False) categorySport = models.BooleanField(default=False) When I register a user it seems to register in the database all correct values for the checkboxes. The problem is when I want to edit user information I cannot see if a checkbox was checked on registering or not, it displays the checkboxes itself, but they are all empty (False). However, it correctly requests the username and displays it so I can edit it, but all the checkboxes are unchecked. views.py: def account_view(request): if not request.user.is_authenticated: return redirect('login') context = {} if request.POST: form = AccountUpdateForm(request.POST, instance=request.user) if form.is_valid(): form.save() context['success_message'] = "Updated" else: # Display the saved user details from database form = AccountUpdateForm( initial = { 'username':request.user.username, "guardianSource": request.user.guardianSource, "bbcSource": request.user.bbcSource, "independentSource": request.user.independentSource, "categoryCoronaVirus": request.user.categoryCoronaVirus, "categoryPolitics": request.user.categoryPolitics, "categorySport": request.user.categorySport, }) context['account_form'] = form return render(request, 'accounts/account.html', context) account html: {% extends 'base.html' %} {% block content %} <form class="form-signin" … -

Double ForeignKey Relation between Models Django
I'm a little confuse here: class MyBirthday(Model): date = models.DateTimeField() invitations_quantity = models.IntegerField() message = models.CharField(max_length=500) user = models.ForeignKey(User) location = models.OneToOneField(Location) class Attendant(Model): user = models.OneToOneField(User, on_delete=models.CASCADE) birthday_id = models.ForeignKey(MyBirthday) The thing is whether or whether not to use the user attribute in MyBirthday model, I mean, is it okay if I just left the Attendant attribute 'birthday_id' reference it? -

Reading Pandas dataframe into postgresSQL with Django

My model contains translated fields in 3 languages class Recipe(AuditBaseModel): recipe_id = models.AutoField(primary_key=True) recipe_code = models.CharField(max_length=30, null=False, blank=False) recipe_name = models.TextField(verbose_name=_('recipe_name'), blank=True, null=True) recipe_name_eng = models.TextField(blank=True, null=True) recipe_name_nor = models.TextField(blank=True, null=True) My template is able to show each field depending on the LANGUAGE_CODE {% get_current_language as LANGUAGE_CODE %} {% if LANGUAGE_CODE == 'en-gb' %}<h2>{{ recipe_form.recipe_name_eng.value }}</h2> {% elif LANGUAGE_CODE == 'nb' %}<h2>{{ recipe_form.recipe_name_nor.value }}</h2> {% elif LANGUAGE_CODE == 'es' %}<h2>{{ recipe_form.recipe_name.value }}</h2> {% endif %} Also, in my template, I have a dropdown menu for language selection <li><a href="">Language</a> <ul class="sub-menu"> <li><a href="">English</a></li> <li><a href="">Norsk</a></li> <li><a href="">Espanol</a></li> </ul> </li> How can I dynamically alter the value of LANGUAGE_CODE in my settings.py when the user selects a specific language from the template menu? Any better idea without using i18n? Many thanks in advance -

is it ok to use formview instead of updateview, createview in Django?
so I'm new here in django and have already get the point of some generic views but it really gives me a hard time to understand the UpdateView, CreateView and DeleteView all information that I search still not giving me a point on how to use them. So I have a form registration which have username and password but they are in different table or model to save; you may take a look on the forms.py, And trying UpdateView its giving me only an error to my project. So as I found in some forums, i can't use UpdateView to a foreign key table for its looking only a primary key So instead of using them I use FormView replacing by the 3 generic view for now. Is it ok to use the FormView as an option aside the 3 generic view? Here is my source code. forms.py: from django import forms class UserCredentialForm(forms.Form): username = forms.CharField(label = 'Email', widget = forms.TextInput( attrs = { 'id': 'id_login_username', 'class': 'form-control', 'autocomplete': 'off', } ), required = False) password = forms.CharField(label = 'Password', widget = forms.PasswordInput( attrs = { 'id': 'id_login_password', 'class': 'form-control', } ), required = False) class UserInfoForm(forms.Form): year = … -
do i need to learn all functions of programming language? [duplicate]
I am new to programming, i know basics of programming. I also write some code in python, php and javascript. Every programming language has hundreds of builtin functions. For example, every programming language has different functions of string, array, int and file I/O etc. Plus framework functions like django, laravel and codeiginter etc. Do i need to learn all builtin functions? for example if i learn php do i need to learn all functions of php plus laravel/codeiginter or if i learn asp.net do i need to learn all functions of c# and asp.net? i don't think it is possible, because there are hundreds of functions in programming language, functions return types and functions parameters? -
Order Union by created_at
I have a graphene.Union of two models and i'm tying to order the response by created_at field, witch is a matching field for both models. Is there of doing that? Schema.py class PostUnion(graphene.Union): class Meta: types = (PostType, Post2Type) @classmethod def resolve_type(cls, instance, info): # This function tells Graphene what Graphene type the instance is if isinstance(instance, Post): return PostType if isinstance(instance, Post2): return Post2Type return PostUnion.resolve_type(instance, info, search) class Query(graphene.ObjectType): all_posts = graphene.List(PostUnion, search=graphene.String(), limit=graphene.Int()) def resolve_all_posts(self, info, search=None, limit=None): if search: filter = ( Q(id__icontains=search) | Q(title__icontains=search) ) return (list(Post.objects.filter(filter)) + list(Post2.objects.filter(filter)))[:limit] return (list(Post.objects.all()) + list(Post2.objects.all()))[:limit] { allPosts(Order: "created_at") { ... on PostType { id title createdAt } ... on Post2Type { id title createdAt } } }
