(Django) automatic record creation for checklist?
I would like the user to be able to select a checklist for a project, however I believe the connection needs to be between the project and a checklist's items, not the checklist itself. This is to allow for an additional boolean field to mark whether an item has been completed for a specific project. However I only want the user to select the checklist name - so how would I code the app to automatically create the appropriate junction_project_checks records upon selecting a checklist? project(models.Model): name = models.CharField(max_length=100) checklist = models.ManyToManyField(checklist) checklist(models.Model): name = models.CharField(max_length=100) checks = models.ManyToManyField(checks, through='junction_checklist_checks') checks(models.Model): name = models.CharField(max_length=100) body = models.TextField() junction_checklist_checks(models.Model): checklist_id = models.ForeignKey(checklist, on_delete=models.CASCADE) checks_id = models.ForeignKey(checks, on_delete=models.CASCADE) junction_project_checks(models.Model): checks_id = models.ForeignKey(checks, on_delete=models.CASCADE) project_id = models.ForeignKey(project, on_delete=models.CASCADE) checkbox = models.BooleanField(default=False) -
How to create a selection based (multiple apps) experiment task in Django?
I am working at an experiment design and want to ask about your opinion and the feasibility with Django. We want to simplify our online experiments (university) and want to create a platform for our researchers to select settings for an online task (Picture 1). These are existing apps like a chatbot. There are also different settings / treatments like the collection of badges. Based on the selection, a website with its selected content and one or more links are generated to send out to a test person (Picture 2). I have some questions about this: How can I display all apps/experiments on one homepage (Picture 1) and generate sites for the selection (Picture 2)? How can I generate unique links for the sites to send them out to probands? Is Django the right option? I now that some of these questions are more opinion-based and I appreciate every answer on that! -

Enable Django support in IntelliJ?
I saw this question, but it doesn't help. I just made a new project in IntelliJ, (Community 2020.1 EAP). This is a Linux OS (Mint 18.3). In the left-hand panel I chose "Python". When I have created it I go File --> Project structure. I click "Facets" in the left-hand panel. In the middle panel it says "No facets are configured" and under that "Detection". I click the "+" sign and then where it says "Buildout Support facet will be added to the selected module" I click OK. After that, in the middle panel, Buildout Support is highlighted, and in the right-hand part it says "Use paths from script:" (with a blank text field) and under the field "Set to <buildout-dir>/bin/django.py for proper Django support". This leaves me very puzzled. It suggests that there is a setting "buildout-dir", and even supposing I can find a file "django.py" in a directory "bin" I haven't got a clue what I'm meant to enter in that box: the full path to "django.py"? The full path above "bin"?

API endpoint for recent/new events in Django Rest Framework
I am trying to make an API endpoint for a mobile app in Django Rest Framework. The challenge I am facing is how to structure and Endpoint that will return the new events. So basically what I want to do is to make requests from the app every 5 seconds to fetch any new events. The events would be e.g a model is created, a model is updated, a model is delete and so on. -
Reduce database hits for Django podcast app
I'm building a podcast directory where episodes can be categorized. The code to generate a page for the podcast, a list of episodes, and a list of categories within each episode. A podcast can have a "Sports" and "News" category. And one episode might have "Sports", while another might have "Sports" and "News" as categories. The problem: I'm battering the database with looping within loops. I know there's a way more efficient way. Here's generally how the models are connected: class Podcast(models.Model): ... class Category(models.Model): podcast = models.ForeignKey(Podcast, on_delete=models.CASCADE) ... class Episode(models.Model): podcast = models.ForeignKey(Podcast, on_delete=models.CASCADE) categories = models.ManyToManyField(Category, blank=True) ... Then, when I load the podcast page and want to put a list of categories and episodes within it: class Podcast(models.Model): ... @property def get_categories(self): return self.category_set.all() @property def episodes_by_category(self): episodes_by_category = [] for category in self.get_categories: episodes = self.episode_set.all().filter(categories=category) episodes_by_category.append({ 'category': category, 'episodes': episodes, 'count': len(episodes), }) sorted_episodes_by_category = sorted(episodes_by_category, key = lambda i: i['count'],reverse=True) return sorted_episodes_by_category Then, when I load an episode page, I show other episodes that share the same categories: class Episode(models.Model): podcast = models.ForeignKey(Podcast, on_delete=models.CASCADE) categories = models.ManyToManyField(Category, blank=True) ... @property def get_categories(self): return self.categories.all().prefetch_related('episode_set').select_related('podcast') @property def related_episodes_by_category(self): episodes_by_category = [] for category in … -
Django third-party backends Access to API
This is my first project with python, and I am building an app with Django Rest Framework. I have made a lot of things in this project, but now I am stuck. I want to generate keys so third-party backends can have access to part of my API and I don’t know how to. For example: someone buys my product (done) and can generate x keys to give access to that API (then I will use DRF throttling to limit the requests). Do I generate keys like tokens and then they have to put it in the header to access? Or is it with Django REST Framework API Key ( https://florimondmanca.github.io/djangorestframework-api-key/ )? Any suggestions? Thanks, Pablo -
Get position of regex matches in database objects using Django
I have a Django app with a Postgres database that takes in user input, makes a regex based on this input, and returns the database entries that match this regex and the start and end positions of this match. The current implementation is something along the lines of: models.py: class SampleInputModel(models.Model): target_field = models.CharField() class SampleInputModelForm(ModelForm): class Meta: model = SampleInputModel fields = '__all__' class RecordObject(models.Model): record_name = models.TextField() record_string = models.TextField() views.py: find_regex_match(form_dict, one_record, terminating_word='keyword'): import re search_pattern = f'({form_dict['target_field']}).*(terminating_word)' for match in re.finditer(search_pattern, one_record.record_string): return '{}\t{}\t{}\t{}\n'.format( one_record.record_name, match.start(), match.end(), one_record.record_string[match.start():match.end()] ) def home(request): if request.method == 'POST': form = SampleInputModelForm(request.POST) if form.is_valid(): form = form.save(commit=False) form = model_to_dict(form) results = '' for one_record in RecordObject.objects.all(): results += find_regex_match(form_dict, one_record) return render(request, 'results.html', {'results': results}) else: form = SampleInputModelForm() return render(request, 'home.html', {'form': form}) This works and takes ~1.2 seconds on average to complete. However, I feel like there's a better way to handle the results instead of just passing a huge raw string to the template to render. I wanted to switch over to using some of the Django API for database filtering so that I can pass query sets to the templates. The new version of the … -
How to Stream mp4 from private bucket using django as a proxy?
I try to return a response to stream a video from a private bucket. To do that my django server will get the video from S3 and return a response. def get_video_from_fragment(self, request, custom_id=None): s3 = AmazonApi() streaming_body = s3.get_file_to_stream(fragment.video.file) if streaming_body is None: return Response({'details': "error retreiving the video"}, status=500) response = StreamingHttpResponse(streaming_content=streaming_body) response['Content-Disposition'] = f'attachment; filename="{fragment.video.filename}"' return response It work well for Chrome and Firefox but not for Safari. I read for Safari that the content need to be delivered with a 206 status code. The things is that my Nginx already deliver well the statics files (mp4 in this case) but not this kind of response. I tried to add response = StreamingHttpResponse(streaming_content=streaming_body, status=206) but in fact, it doesn't change anything. I test with a curl like they do on their documentation (from apple) I suppose that my nginx (or django) know how to manage my .mp4 files but don't know how to do with call that return a StreamingHttpResponse. Also I check how others website deliver their content and I see on my Safari console network tab a difference on the status. For example google website has a status code on Response Headers but mine are … -

Django 3.x - which ASGI server (Uvicorn vs. Daphne)
I have a simple API-based web application written in Django, and I decided to upgrade Django from 2.x to 3.x. In Django docs there's a documentation page about ASGI servers, and two options are mentioned: Daphne and Uvicorn. Unfortunately they do not provide any benefits regarding a particular choice, so I'm confused when it comes to select one of them. I would like to hear opinions of people who have experience with both libraries, and I would like to ask mainly for opinion on performance and stability. And, basically, is it a big difference to use Uvicorn instead of Daphne? My server is running on Ubuntu, so Daphne seems to be the right choice, as it's designed to be used on UNIX system. -

Django - sqlite - Delete attribute from model
I am a beginner in Django and up to now I was amazed how simple it was. I am running django 3 with an sqlite3 DB. I want to remove an attribute of one of my models. In this particular case it's "slug". models.py class Recipe(models.Model): title = models.CharField(max_length=100) creator = models.CharField(max_length=42) content = models.TextField(null=True) creation_date = models.DateTimeField(default=timezone.now, verbose_name="Creation date") photo = models.ImageField(upload_to="photos/") main_ingredient = models.ManyToManyField('Ingredient', related_name='recipes') slug = models.SlugField(max_length=100) class Meta: verbose_name = "recipe" ordering = ['creation_date'] def __str__(self): return self.title I just delete the line and ran python manage.py makemigration I got the following error SystemCheckError: System check identified some issues: ERRORS: <class 'recipes.admin.RecipeAdmin'>: (admin.E027) The value of 'prepopulated_fields' refers to 'slug', which is not an attribute of 'recipes.Recipe'. I suppose django does not want to delete the line from the DB. I have to do it manually then I tried this But it does not work for sqlite as explained here So far I was amazed by Django and this is a major drawback. Is there an easier way? what am I doing wrong?

Django Postgres search with SearchVectorField and TrigramSimilarity
I'd like to do efficient partial word matches with a large data set. I'm able to use SearchVectorField for speed and as a way to collect data from a few different fields. search_vector = SearchVectorField(editable=False) Thing.objects.update(search_vector=various_fields_vector) Thing.objects.filter(search_vector="something") Works quickly. However it doesn't perform partial word matches. Thing.objects.filter(search_vector="omething") Yields no results. I want to do something like Thing.objects.annotate(rank=TrigramSimilarity("search_vector", "omething")) However I get: No function matches the given name and argument types. You might need to add explicit type casts. Is there a way to index in some manner to perform these searches faster? -
Does Heroku WEB_CONCURRENCY need to account for ALL processes spawned by both Django AND task queue (such as; Huey, Celery) on the same dyno?
I am trying to deploy Django and Huey async task queue to the same dyno. I understand that people usually deploy a task queue to a separate dyno/container for independent scaling and what not. That reason for me doing this is because Huey is a light weight task queue and as such if there is a need for some async works or occasional scheduling, it could handle it (no need for heavy-weight like Celery in a separate dyno). Here is what sample Huey configuration in Django settings.py look like. I have used "process" as worker type and there are 3 of them (plus 1 mandatory consumer process) for a total of 4 for Huey. My question, do I have to account for that number in addition to Django process when setting WEB_CONCURRENCY? Or does the WEB_CONCURRENCY only apply to Django web request handler. I am not entirely how Gunicorn handle Django. -

run a javascript function inside a python
