How to use JavaScript in included components in Django?
In short, how to use JavaScript in the component that will be then included in the main page? A standard approach in Django templates is to create a base.html template and then extend it. That base template usually has blocks like content, extra_js, and extra_css. The extended template looks like {% extend 'base.html' %} {% block content %} <div> some content </div> {% endblock %} {% block extra_js %} # some js code here {% endblock %} I need to create a component that will be included on several pages and I need to use JavaScript inside that component. I know that it will be included only on pages that extend base.html, the page that includes it will look like {% extend 'base.html' %} {% block content %} <div> {% include 'component.html' %} </div> {% endblock %} {% block extra_js %} # some js code here {% endblock %} However, component.html knows nothing about extra_js block because it doesn't extend base.html, I cannot use that block in component.html, and if I just put some JavaScript code in it then after the template is rendered any JavaScript in component.html will end up being in the middle of the body of the … -
django-filer import file paths from mysql to postgresql
Recently I changed the database in my Django app from MySQL to PostgreSQL. I moved all text values and folders successfully from staging to the production environment but I am struggling with paths to media files that are stored on Azure Storage. I am using the same settings in my settings both in production and staging environments: DEFAULT_FILE_STORAGE = 'backend.custom_azure.AzureMediaStorage' MEDIA_LOCATION = "media" AZURE_ACCOUNT_NAME = config('AZURE_ACCOUNT_NAME') AZURE_CUSTOM_DOMAIN = f'{AZURE_ACCOUNT_NAME}.blob.core.windows.net' MEDIA_URL = f'https://{AZURE_CUSTOM_DOMAIN}/{MEDIA_LOCATION}/' The problem is that I connected all files on staging and when I am trying to manually export from mysql and import in postgresql filer_file and filer_image tables I am getting this error: Exception Type: Polymorphic Type Invalid at /homepage Exception Value: Content Type 37 Question Basically what I want is to copy folders and files that are on staging (paths stored in MySQL) and pasting/uploading/importing them on production (paths stored in PostgreSQL) so my question is how to resolve this issue. I don't want to connect each image once again in each model because there are hundreds of them already. Is there any way I can import them into PostgreSQL in a way that when I open the admin panel in the production environment it will show … -
Why is the returned result of the Elasticsearch response still caped at 10000 when the parameter max_result_window has been changed?
I have a Django application with Elasticsearch. I have an index where I need to render more than 10 000 results. I changed manually the parameter max_result_window to render more than the 10 000 initial limit. But after changing the parameter max_result_window and the size in the body_search of my request, the result keeps being limited to 10 000. First, I have changed the parameter max_result_window to 12345 of the search_index, by using the method from the page Result window is too large, from + size must be less than or equal to: [10000] but was [100000]. I checked on http://localhost:9200/search_index/_settings, and I have the following result "max_result_window":"12345". Then I changed the parameter size of my body_search = {'query': {...}, 'size': 12345}. But the final result is always limited at 10 000. Does anyone has an idea what the change is not take into account in my search ? -
How to upload files through BSModalCreateView using an inline formset?
I'm currently trying to upload a file in a BSModalCreateView while using an inline formset and have it saved in a folder for testing purposes that has full permissions for read/write. When trying to print out which file was uploaded to the InMemoryUploadedFile class, nothing will be prinited out. If I comment out the function def get_success_url() (views.py) to throw an error, I can see the file is being uploaded to the InMemoryUploadedFile class: I'm not sure if I'm missing something in the function def doc_valid() (views.py) or something with my inline formset. Any guidance will be appreciated, thanks! base.py MEDIA_ROOT = os.path.join('home/my-location/') MEDIA_URL = 'media/' Views.py from datetime import datetime as dt from django.urls import reverse from bootstrap_modal_forms.generic import ( BSModalCreateView ) from users.forms.documents import DocumentForm, DocumentFormSet from users.models.documents import Document from users.models.users import User class DocumentCreateView(BSModalCreateView): form_class = DocumentForm template_name = 'partials/test.html' success_message = 'Document added successfully' def get_success_url(self): return reverse('users:detail', args=[self.kwargs.get(self.slug_url_kwarg)]) def get_context_data(self, *args, **kwargs): context = super(DocumentCreateView, self,).get_context_data(*args, **kwargs) context['action'] = 'Upload' context['object_type'] = 'a Document' context['user_to_edit'] = User.objects.get(username=self.kwargs.get(self.slug_url_kwarg)) if self.request.POST: context['docfiles'] = DocumentFormSet(self.request.POST, self.request.FILES, instance=self.object) else: context['docfiles'] = DocumentFormSet(instance=self.object, initial={'user': context['user_to_edit'].id}) return context def doc_valid(self, request): context = self.get_context_data() form = context['docfiles'] self.object = form.save() … -
Invalid hex encoding in query string
im currently working on a DJango search with multiple query_params, since im using Sentry i found out that sometimes there's an issue triggered when you search for example something with percentages: "100% natural" "100% unique" "50% blah blah blah" Sentry: Unhandled Invalid hex encoding in query string. This is marked in the oauth lib if INVALID_HEX_PATTERN.search(query): raise ValueError('Invalid hex encoding in query string.') The current search code allows to pass any query_param like this: re_path(r"^search/?$", search_system, name="search") And inside the view i do have this: query = request.query_params.get("query") query = query.replace("%20", " ") if query else None i tried to replace the %20 for an space, but sometimes it happens and sometimes it doesn't so it happens randomly, i don't know if im doing something wrong, or actually the question would be: is there anything i could do to avoid triggering this alert without doing anything in sentry? for example like cleaning up the data like a form Thanks in advance. To avoid this issue i tried to set the query replace("%20", " "), my best guess is that the error is triggered when you have the "percentage + space" next to each other so the url looks like search/100%25%20natural … -

Django - loop through the records and update database on conditions with scheduled task
How to run a scheduled task from example task file scheduled_task.py file to access models.py (e.g. Event) and if certain criteria is met, update one of the fields in database (example: event_status)? models.py class Events(models.Model): event_title = models.CharField(max_length=300) event_info = models.TextField(max_length=2000) event_date = models.DateField(default=now) event_time = models.TimeField(default='00:00') event_location = models.CharField(max_length=150) event_status = models.CharField(max_length=30, choices=EVENT_STATUS_CHOICES, default='New Event') def save(self, *args, **kwargs): if date.today() > self.event_date: self.event_status = 'Completed Event' super(Events, self).save(*args, **kwargs) What should be code to iterate through all events from database, and update it's record? scheduled_task.py from models import Events def verify_events(): all_events = Events.objects.all() for event in all_events: if event.event_date < date.today(): event.event_status = 'Completed Event' event.save() The code runs, but nothing happens (no error), db is not refreshed with changes. The current save() for Events under models.py does the work when you refresh the page, they it runs the save() function, but I want this to be always up to date without refreshing the page manually to trigger the save() function - so it can happen overnight (I am using Tasks in PythonAnywhere). Is the event.save() incorrect? not saving while integrating through the Events? Thanks for help -
Django - Apply model on many (1000's) foreign key objects in admin
I have a model of a football coach and a model of a membership payment which has a foreign key to the coach model. In the admin, I want to be able to apply the membership to a lot of coaches at once and not only to one coach. In essence, I imagine a raw_id field which is selectable. The coach has a field balance and the membership model deducts on save some amount from that field of the coach. Is something like this possible? Here are my models: class Trener(models.Model): class Meta: verbose_name = 'Trener' verbose_name_plural = 'Treneri' prezime = models.CharField(max_length=100) #new ime = models.CharField(max_length=100) balans = models.IntegerField() #new def __str__(self): return str(self.prezime) and my membership model: class Clanarina(models.Model): class Meta: verbose_name = 'Clanarina' verbose_name_plural = 'Clanarine' trener = models.ForeignKey(Trener, on_delete=models.CASCADE) datum_naplate = models.DateField() opis = models.CharField(max_length = 200, blank=True, null=True) iznos = models.IntegerField( verbose_name="iznos (uneti pozitivan broj)") # @property # def naplata(self): # self.trener.balans -= self.iznos # self.trener.save() # return def save(self, *args, **kwargs): self.trener.balans -= self.iznos self.trener.save() super(Clanarina, self).save(*args, **kwargs) Thank you very much in advance!

Paginated REST API endpoint for django-simple-history records, using Django REST Framework
I'm using django-simple-history to track model changes. It's easy enough to get all history records for a model class or a model instance: poll = Poll.objects.create(question="what's up?", pub_date=datetime.now()) poll.history.all() # and Choice.history.all() But what I'm looking to do is to have endpoints like /history/model and /history/model/1 that returns paginated history records for either the class or class instance. Now I've already got Django REST Framework (DRF) set up with pagination, and have all my views paginated, something like: class MyModelViewSet(viewsets.ModelViewSet): serializer_class = MyModelSerializer permission_classes = [permissions.IsAuthenticated] queryset = MyModel.objects.all() class MyModelSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = MyModel fields = ["name"] class MyModel(models.Model): name = models.CharField(max_length=100, unique=True) That all works fine. How can I paginate the django-simple-history records? Can I create a simple history serializer? Because there's not exactly a simple history model I can use (I think). -

Django project doesnt insert into Oracle table
I'm building a integration app that consumes data from a API and save the sensitive information into a table inside a oracle database. My models succesfully migrated and created the tables and I was able to also succesfully consume and filter the data I need from the API, so I proceeded to use objects.update_or_create to populate my table with the data, initially it worked fine and inserted the information normally until it got stuck and stoped the querys. After that I droped the tables and started the migration process anew, and also changed my method to objects.create with .save(force_insert=True) to brute force the process and insert the data inside the table, but the problem persisted and I'm kinda lost not knowing what is wrong mainly because it doesnt raise any error nor exception and just remains stuck into the block. for item in value_list['itens']: print(item) i = Item.objects.using('adm_int').create( nature=item['nature'], nr_doc=item['nr_doc'], name=item['name'], value=item['value'], type_op=item['type'], description=item['history']['description'], ) i.save(force_insert=True) Inside the response from the API there'll be N number of itens, so I need to insert the data from each item into the table. When it begins the loop it doesnt insert the data and stops there. -

How to configure webpack to generate SuiteScript compatibile modules?
I am trying to use webpack to bundle a few libraries into my typescript suitelet. Netsuite expects suitescripts to follow amd modules pattern. If I use tsc tocompile my suitelet, I get correct syntax that looks this fragment: /** * * @NApiVersion 2.x * @NScriptType Suitelet */ define(["require", "exports", "N", "N/file"], function (require, exports, N_1, file_1) { "use strict"; Object.defineProperty(exports, "__esModule", { value: true }); exports.onRequest = void 0; var onRequest = function (context) { //my actual code here }; exports.onRequest = onRequest; }); The poblem is that the dependencies from node_modules are not bundled. So I have tried to use webpack for this, and webpack output differs: /** * * @NApiVersion 2.x * @NScriptType Suitelet */ define(["N", "N/file"], (__WEBPACK_EXTERNAL_MODULE__N, __WEBPACK_EXTERNAL_MODULE__Nfile) => { return (() => { //... some webpack internals goes here var __webpack_exports__ = {}; // This entry need to be wrapped in an IIFE because it need to be isolated against other modules in the chunk.

Post form redirect not retrieving resource django
I am sending a POST request to one of my views via fetch upon clicking a form's button in javascript. The POST request resolves and reaches a redirect, but the redirect does not render the corresponding view, rather the page remains on the same view. I have configured the urls with the views, name-spaced the application and I am overall unsure where I went wrong here, particularly because the resource is indeed returned from the redirect, but just not rendered.

Then I call the form, and indeed all the entries show up, including a cell for User, however it shows no options or pre-selection for current user. What am I doing wrong? #User as rendered in form in browser: <select name="researcher" id="id_researcher"> <option value="" selected>---------</option> models.py from django.db import models from django.contrib.auth.models import (BaseUserManager, AbstractBaseUser) class User(AbstractBaseUser): is_active = models.BooleanField(default=True) def get_full_name(self): """ Return the first_name plus the last_name, with a space in between.

Django Many To Many Ordering
I have two tables Subjectlist and Day. Subject list is m2m in Day. So my problem is I'm creating school timetable. So for each days different subjects to be shown, when i add subjects on each days the order of subject is same. #Models.py class SubjectList(models.Model): subject_name = models.CharField(max_length=25) def __str__(self): return self.subject_name class Day(models.Model): day_name = models.CharField(max_length=15) subject_name = models.ManyToManyField(SubjectList) class_number = models.ForeignKey(AddClass, on_delete=models.CASCADE, null=True, blank=True) start_time = models.TimeField(null=True, blank=True) end_time = models.TimeField(null=True, blank=True) def __str__(self): return self.class_number.class_number #Views.py class TimeTableView(APIView): def get(self, request, id): class_number = AddClass.objects.get(id=id) day = Day.objects.filter(class_number=class_number.id) print(day) serializer = DaySerializer(day, many=True) return Response(serializer.data) I want to do like this Monday - English, maths, science, Social Science Tuesady - Maths, Social Science, Englih, Math's but i get like this Monday - English, maths, science, Social Science Tuesday- English, maths, science, Social Science both are in same order even if add subjects in different order.
