django full text search taggit
My application - the basics I have a simple django application which allows for storing information about certain items and I'm trying to implement a search view/functionality. I'm using django-taggit to tag the items by their functionality/features. What I want to implement I want to implement a full text search which allows to search across all the fields of the items, including their tags. The problem(s) On the results view, the tagged items are showing up multiple times (one occurence per tag) The ranking is correct when I specify * only a single* tag in the search field, but when I specify multiple tag names, I will get unexpected ranking results. I suspect the SearchVector() does not resolve the tags relation as I expected it to do. The tags should be treated just like a list of words in this case. Example Code models.py from django.db import models from taggit.managers import TaggableManager class Item(models.Model): identifier = models.SlugField('ID', unique=True, editable=False) short_text = models.CharField('Short Text', max_length=100, blank=True) serial_number = models.CharField('Serial Number', max_length=30, blank=True) revision = models.CharField('Revision/Version', max_length=30, blank=True) part_number = models.CharField('Part Number', max_length=30, blank=True) manufacturer = models.CharField('Manufacturer', max_length=30, blank=True) description = models.TextField('Description', blank=True) tags = TaggableManager('Tags', blank=True) is_active = models.BooleanField('Active', default=True) forms.py … -

Issue with dictionary values not appending in Django session
I'm encountering an issue with updating dictionary values in Django session. Initially, I was using a list to store data in the session, and it worked perfectly fine. However, when I switched to using a dictionary to store the data, I noticed that the values were not getting appended as expected. Instead, the new data was replacing the old data in the dictionary. views.py: def pushups(request): if "record" not in request.session or not isinstance(request.session["record"], dict): request.session["record"] = {} return render(request, ("App_4/record.html"), { "record" : request.session["record"] }) def add(request): if request.method == 'POST': form = Add_record_form(request.POST) if form.is_valid(): a = form.cleaned_data["add_form"] b = request.session["record"] b[f"{date.year}-{date.month}-{date.day} {date.hour}:{date.minute}:{date.second}"] = a request.session["record"] = b return HttpResponseRedirect(reverse("App_4:view_record")) else: return render(request, "App_4/add_record.html", { "add_form" : form }) return render(request, ("App_4/add_record.html"), { "add_form" : Add_record_form() }) record.html {% for key,value in record.items %} <tr> <td>{{key}}</td> <td>{{value}}</td> </tr> {% empty %} <tr> <td>no tasks</td> </tr> {% endfor %} The strange thing is that the dictionary values only get updated correctly if I make changes in the views.py file or just simply click CTRL+S before adding new data. Otherwise, the previous data just gets replaced. This issue wasn't present when I was using a list instead of a dictionary. … -
Nested for loop - model.id in parent for loop does not match model.id in nested for loop (django)
I am trying to access data from a parent to a child via a foreign key. WHAT WORKS - the views The data in the child is not "ready to be used" and need to be processed, to be represented in a progress bar in %. The data processing is handled in the views. When I print it on the console, it seems to work and stored into a variable reward_positions. Reward positions = [(<Venue: Venue_name>, reward_points, reward_position_on_bar)] So this part works. The plan is therefore to access reward_position_on_bar by calling {{reward_positions.2}} WHAT DOESNT WORK - the template But something is not working to plan in the template. The template renders the last child_model (thats rewardprogram) objects of the last parent_id (thats venue) irrespective of the actual parent_id processed in the for loop. TEST RESULT & WHERE I THINK THE PROBLEM IS I think my problem lies in my nested forloop. The parent_id in the parent forloop does not match the '{{reward_position.0}}' in the nested forloop. Doing a verification test, {{key}} should be equal to {{reward_position.0}} as they both go through the same parent forloop. However, if {{key}} does change based on venue.id (parent forloop id), {{reward_position.0}} is stuck to … -
Django orm filter many to many fields
The question is this. There are Project and User models. In the Project model, there are 2 ManyToMany links to the users model. class Project(models.Model): name = models.CharField(max_length=100) content = models.TextField() creaters = models.ManyToManyField('User', related_name='creater_projects') workers = models.ManyToManyField('User', related_name='worker_projects') class User(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) I need to filter the projects depending on the transferred user.id You can filter as follows from django.db.models import Q user_id = 1 Project.objects.filter(Q(creaters__id=user_id) | Q(workers__id=user_id)) What other ways are there to do similar filtering? -

Queryset to update set of values for a field
What queryset can I use to translate the values of a field from one set of values to another set? For example, lets say I have a User model with a CharField containing the name of a country and I wish to update the name of some of the countries for all users using the following dict: new_country_names = {"Micronesia": "States of Micronesia", "Macedonia": "North Macedonia"} I obviously want to avoid doing this by looping over each user and checking the value of their country. -

Django - problem re-adding goods to the basket
I am creating an online store on Djnago. The project has a basket in which you can place goods, as well as remove them. Goods are placed and removed without problems.

How do I run a Django GitHub workflow CI with .env file for secret management
I have my django project using a local .env file on my windows computer that never gets committed to the repo. However, for GitHub CI testing it needs to read the secrets for the settings.py from somewhere and since it doesn't have the .env file it cannot run any tests and crashes. How would I solve this problem? I am using python-dotenv package to read my secrets from the .env local file when developing. I basically want to run tests automatically on my GitHub repo on every push to main branch with secret management. The only solution that I could find was to create a .env file within the GitHub workflow as a step before running the test, but that is a bit crummy because then you are leaking out your .env fields and what exists on there. - name: Create .env file run: | echo "SECRET_KEY=123456" > .env .... How should I solve this problem? -

Django ORM - 'annotate' and 'order_by' doesn't seem to work equivalently to 'GROUP BY' and 'ORDER BY'?
Summary: ordered_tags = tagged_items.annotate(freq=Count('tag_id')).order_by('-freq') for i in ordered_tags: print(i.tag_id, i.tag, i.freq) This does not work equivalently to GROUP BY tag_id ORDER BY COUNT(tag_id) DESC. Why? Using Django ORM, I am trying to do something like: SELECT tag_id, COUNT(tag_id) AS freq FROM taggit_taggeditem WHERE content_type_id IN ( SELECT id FROM django_content_type WHERE app_label = 'reviews' AND model IN ('problem', 'review', 'comment') ) AND ( object_id = 1 OR object_id IN ( SELECT id FROM review WHERE problem_id = 1 ) OR object_id IN ( SELECT c.id FROM comment AS c INNER JOIN review AS r ON r.id = c.review_id ) ) GROUP BY tag_id ORDER BY freq DESC; So here's what I have contrived: querydict_for_content_type_id = { 'current_app_label_query' : Q(app_label=ReviewsConfig.name), 'model_name_query' : Q(model__in=['problem', 'review', 'comment']) } # used in content_type_query query_for_content_type_id = reduce(operator.__and__, querydict_for_content_type_id.values()) # Query relevant content_type from TaggedItem model. content_type_query = Q(content_type_id__in=ContentType.objects.filter(query_for_content_type_id)) # Query relevant object_id from TaggedItem model. object_query = Q(object_id=pk) | Q(object_id__in=problem.review_set.all()) for review in problem.review_set.all(): object_query |= Q(object_id__in=review.comment_set.all()) tagged_items = TaggedItem.objects.filter(content_type_query&object_query) # JOIN Tag # tags = tagged_items.select_related('tag') # GROUP BY freq ORDER_BY freq DESC; ordered_tags = tagged_items.annotate(freq=Count('tag_id'))#.order_by('-freq') for i in ordered_tags: print(i.tag_id, i.tag, i.freq) Django ORM doesn't work as intended.

Connection reset by peer on file upload if JWT expires
We have a django app and it supports a file upload request. The entire upload comprises multiple requests. We are authenticating with JWT and we have logic to handle a 401 and in that case use the refresh token to get a new access token and resend the failed request. However if the token expires between 2 requests of the same upload the 401 response never makes it to the client. In the logs I found that before nginx gets the response we get this error: 2023/06/02 16:23:11 [error] 1924925#1924925: *75 readv() failed (104: Connection reset by peer) while reading upstream, client: xx.xx.xx.xx, server: example.com, request: "POST /api/upload/ HTTP/1.1", upstream: "uwsgi://unix:///bar/foo/our_app/app.sock:", host: "", referrer: "http://example.com:8082/" This causes the client to get an empty response body and the browser throws a ERR_CONTENT_LENGTH_MISMATCH error. The entire upload takes under 10 minutes and we have all the timeouts set to 100 minutes: uwsgi_read_timeout 6000; uwsgi_connect_timeout 6000; uwsgi_send_timeout 6000; send_timeout 6000; proxy_read_timeout 6000; proxy_send_timeout 6000; What is causing the socket to get closed? How can I prevent that? Are there other timeouts I could set? Any logging that I can enable to see why the socket is getting closed? Is there a way to … -
Django model: Query of query or filter of filter
I have 2 models, and on the function, I need to filter in 'x' the users which has the id's equal the id's received. And secondly, I need to filter in another query (let's say 'y'), the description from model Detail, which has the person_id equal to the id's already filtered in 'x'. It's like a filter of a filter, or a query of a query. class Person(models.Model): user = models.ForeingKey(Users, on_delete=models.CASCADE) name = models.CharField(max_length=50) class Detail(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) description = models.TextField() def test(request, id_user): x = Person.objects.filter(user_id = id_user) I don't know how to do it. I'm new to Python and Django. It would be something like this: y = Detail.objects.filter(person_id = id_x). But of course, this isn't right. Can someone help me? -
