Custom Django JSON field with additional API information
I want to implement a custom json field that would take in the id and put it in json together with other API information. Let's say you receive an id of 2, so you want to put it together in the database like this: { "id": 2, "API": "path-to-api", "additional-info": ... } The additional info, API and other keys added to the json are known at the field declaration time, and they are always the same for the given column. I used Django's get_prep_value to change the value inserted into the DB. I am also using django rest framework ModelSerializer and generics for the views. When I create a new entry, the POST response doesn't have the correct JSON, just the id I sent it. However, if I look into the database, I can see that the value is saved in the correct way and if I list the values using the default generics ListCreateAPIView, I receive the correct JSON. So the question is: Can I do this kind of functionality somehow on the field level? -
Filter queryset based on related object's field value
I have two models: class PartUse(models.Model): ... imported = models.BooleanField() class PartReturn(models.Model): partuse = models.ForeignKey(PartUse) ... imported = models.BooleanField() class PartUseListView(ListView): model = PartUse def get_queryset(self): if self.request.GET.get('show_imported', None): qs = self.model.objects.all() else: qs = self.model.objects.filter(imported=False) // including related return qs I want to filter QuerySet for PartUse to return all PartUse instances that have imported == False for either model. What's the best way to achieve that? -

Django does not create a multi-language sitemap
According to the documentation I made a site map, the site is multilingual, but instead of a normal map it displays a list of url without spaces. And it does not create a version of the page for each language. sitemap.py from django.contrib.sitemaps import Sitemap from movies.models import Movies class DynamicViewSitemap(Sitemap): changefreq = 'weekly' i18n = True languages = ["en", "ru", "de", "es","pt", "fr"] alternates = True x_default = True def items(self): return Movies.objects.all() def location(self, item): return f'/movies/{item.slug}/' urls.py sitemaps = { 'dynamic': DynamicViewSitemap } urlpatterns = [ path('admin/', admin.site.urls), path('i18n/', include('django.conf.urls.i18n')), path('sitemap.xml', sitemap, {'sitemaps': sitemaps}), Result: https://wherefilmed.org/sitemap.xml -

How to use URL patterns in a HTML file using Django?
I am creating a web application in Django, and I need to link to a webpage that creates a model and then redirects you back. I have already created this webpage, but I need to create a link to it. This is the URL pattern for it (yes, it is long and ugly): path('add_to_trip/<int:id>/<str:name>/<str:addr>/<str:rating>', add_to_trip, name="add_to_trip"), I am trying to use this link to redirect to it, but Django can't understand it. <a class="btn btn-primary" href="{% url 'add_to_trip/{{trip_id}}/{{place_results_name}}/{{place_results_addr}}/{{place_results_rating}}' %}" style="margin-top: 10px;">Add to trip</a> This is the error I am getting: NoReverseMatch at /plan/3/ Reverse for 'add_to_trip/{{trip_id}}/{{place_results_name}}/{{place_results_addr}}/{{place_results_rating}}' not found. 'add_to_trip/{{trip_id}}/{{place_results_name}}/{{place_results_addr}}/{{place_results_rating}}' is not a valid view function or pattern name. I don't know why Django isn't using the URl pattern I provided. -
In django, how do I pass in context to a view for a specific entry in my database?
I'm quite new to django and python so please bear with me. I'm trying to create a view inside my django project that will display one entry inside my database. I have a specific template for how I want the data in the entry to be displayed. I have an app inside my project called card_catalog. Inside this app I have a function based view. Here is the code from the views.py file. def flashcard_view(request): sentence = Flashcard.objects.values_list('sentence',flat=True) word_dict_form = Flashcard.objects.only('word_dict_form') ipa = Flashcard.objects.only('ipa') pos = Flashcard.objects.only('pos') word_trans = Flashcard.objects.only('word_trans') sent_trans = Flashcard.objects.only('sent_trans') context = { 'sentence':sentence, 'word_dict_form':word_dict_form, 'ipa':ipa, 'pos':pos, 'word_trans':word_trans, 'sent_trans':sent_trans } return render(request,'card_catalog/flashcard_view.html',context=context) Here is the code for the flashcard model in the models.py file: class Flashcard(models.Model): #Main fields sentence = models.CharField(max_length=250,null=True,blank=True) word_dict_form = models.CharField(max_length=50,null=True,blank=True) word_inflected_form = models.CharField(max_length=50,null=True,blank=True) ipa = models.CharField(max_length=50,null=True,blank=True) pos = models.CharField(max_length=50,null=True,blank=True) word_trans = models.CharField(max_length=50,null=True,blank=True) sent_trans = models.CharField(max_length=250,null=True,blank=True) # sound_word = # sound_sentence = # notes_visible # notes_not_visible # Card Activation fields activate_nw_card = models.BooleanField(default=True) activate_pic_word_card = models.BooleanField(default=True) activate_word_sent_card = models.BooleanField(default=True) activate_lr_card = models.BooleanField(default=False) activate_inflected_form_card = models.BooleanField(default=False) activate_pron_card = models.BooleanField(default=False) activate_spell_card = models.BooleanField(default=False) activate_trans_word_card = models.BooleanField(default=False) activate_sent_trans_card = models.BooleanField(default=False) # Image Links image_1_url = models.URLField(max_length=500,null=True,blank=True) image_1_overlay = models.URLField(max_length=500, null=True, blank=True) image_2_url = models.URLField(max_length=500, null=True, blank=True) image_2_overlay … -

How do I change a function written in for loop into a single query set?
I have some django query as bellow. There is a monthly_date column in Building model, and I have my custom function get_start_date to calculate the date from monthly_date. This code with for loop works well. target = [] for building in Building.objects.filter( contract_date=view.base_date, ): if building.payments.filter(scheduled_date__lte=get_start_date(building.monthly_date)): target.append(building) I'm trying to remove for loop to make it only one query. Building.objects.filter( contract_date=view.base_date, payments__scheduled_date__lte=get_start_date(F('monthly_date')) ) I tried with F but I got RecursionError . There is some while loop in get_start_date but it works well with for loop so I don't know why this error occur. date_map = {datetime.date(2023, 2, 19): datetime.date(2022, 11, 18)} Building.objects.filter( contract_date=view.base_date, payments__scheduled_date__lte=date_map[F('monthly_date')] ) I tried like this after calculated date_map first from monthly_date, but KeyError: F(monthly_date) occur this time. What should I do to make it one query? -

Django Admin - Show ManyToOne data on a model in admin
I have 2 models Patient and History. I would like to show all History of a Patient inside the Patient model in django admin as table. I was thinking to use ManyToOne field as one patient can have more than 1 history and 1 history is only owned by 1 patient. In the Patient model admin I would like to also be able to add a new history. I have tried to use ManyToMany field but doesn't looks like the solution. Can anyone please help me on how to solve this?

How to keep some variables of a template after post request in Django
I’ve been using Django for some time and I have a kind of question about how I code after I’ve been on forums. My heaviest page requires generating several objects that I send in the context of my view. I organized my view this way: def myFunction(request): if request.method == 'POST' and "some_Button" in request.POST : #when click on a button #update object_2 elif request.method == 'POST' and "another_Button" in request.POST : #when click on another button #update object_1 else: #part executed at first load myFunction.object_1 = #some code myFunction.object_2 = #some code myFunction.object_3 = #some code context = {'object_1' : myFunction.object_1, 'object_2' : myFunction.object_2, 'object_3' : myFunction.object_3} return render(request, 'index.html', context) I had found the practice of writing my context's variables like MyFunction.myVariable in order not to have to regenerate them all when I just want to change an object. Like here when I click on one of the buttons I don’t have to regenerate the other variables. However, I am aware that this is not a good practice and I would like to change that. Except that all the examples I find need to regenerate all the variables each time. I thought about using the cache to temporarily … -

Django Rest Serializer: How to get hyperlink when read, use id when create or update?
models.py class User(models.Model): name = models.CharField(max_length=300) class Booking(models.Model): time = models.DateTimeField() user_id = models.ForeignKey(User, related_name='booking', on_delete=models.CASCADE) serializers.py class UserSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = User fields = '__all__' class BookingSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Booking fields = '__all__' With the above code, I would get an error user_id ":["Incorrect type. Expected URL string, received int."] during creating booking process. I believe this because HyperlinkedModelSerializer expect a URL for the foreign key field. However, passing an ID during creating or updating is way more convenient. How can I edit this so that it can use id when create or update and return hyperlink only when read? -

Getting django model entries with a more complex query (joining with no direct relationship)
I am trying to get the model entry for a certain query where I'm joining with columns that are not the ForeignKey of the table. My tables (models) look like this (simplified with necessary columns): class PE(models.Model): # table p_e p_e_id = models.AutoField(primary_key=True) p_o = models.ForeignKey('PO', models.DO_NOTHING) p_r = models.ForeignKey('PR', models.DO_NOTHING) s_o = models.ForeignKey('SO', models.DO_NOTHING) item = models.ForeignKey(Items, models.DO_NOTHING, related_name='pe_item') p_e_is_possible = models.BooleanField() class EIH(models.Model): # table e_i_h e_i_h_id = models.AutoField(primary_key=True) target_item = models.ForeignKey('Items', models.DO_NOTHING,related_name='target_item') component_item = models.ForeignKey('Items', models.DO_NOTHING,related_name='component_item') p_o = models.ForeignKey('PO', models.DO_NOTHING) p_r = models.ForeignKey('PR', models.DO_NOTHING) class Items(models.Model): item_id = models.AutoField(primary_key=True) The Query I am currently using without models looks like this: SELECT * FROM p_e INNER JOIN e_i_h ON e_i_h.target_item_id = p_e.item_id AND e_i_h.component_item_id = -1 AND (e_i_h.p_o_id = p_e.p_o_id OR (p_e.p_e_is_possible = True AND p_e.s_o_id != -1) ) Is it possible to get the same queryset result as the Query only using models? The result is one entry from the table EIH with the query. I tried to filter the EIH objects with joining over the items table: pe_queryset = PE.objects.filter(item_id=15) for pe in pe_queryset: erp = EIH.objects.get(Q(p_o_id= pe.p_o.p_o_id) | Q(pe.p_e_is_possible=True), item_id=pe.item.item_id, component_item_id=-1) I also tried lookup: erp = EIH.objects.get(Q(p_o_id= pe.p_o.p_o_id) | Q(target_item__p_e__p_e_is_possible=True), item_id=pe.item.item_id, component_item_id=-1) The problem … -
Meta.ordering is deprecated option, what is the alternativeoption
I have updated my Django project from version 2 on version 3.2, and I have found in documentation that Meta.ordering option is deprecated. Actually this is in documentation: 'Meta.ordering will be ignored in such queries staring in Django 3.2'. I would like to if there is some another attribute in Meta class or in my main class in order to have same order impact. Project is really big, so I can not use order_by() with every filter.

Django project guidance required
This is a small project given to me. I need help. If possible, give me the code files in Django: Create a REST api to be consumed by a mobile app which tell you if a number is spam, or allow you to find a person’s name by searching for their phone number. Each registered user of the app can have zero or more personal “contacts”. The “global database” is basically the combination of all the registered users and their personal contacts (who may or may not be registered users). The UI will be built by someone else - you are simply making the REST API endpoints to be consumed by the front end. Data to be stored for each user: Name, Phone Number, Email Address. Registration and Profile: A user has to register with at least name and phone number, along with a password, before using. He can optionally add an email address. Only one user can register on the app with a particular phone number. A user needs to be logged in to do anything; there is no public access to anything. You can assume that the user’s phone contacts will be automatically imported into the app’s database …
