Can not configure postgres database in GitHub actions pipeline using Docker
I am creating pipeline for my Django Project with GitHub actions and can't make it working correctly. As I use docker, when I start the Docker and start my tests with 'python manage.py test' it works correctly. But when my tests are started I get an error. The reason is probably is that it does not know how to connect to DB, as Docker works with that in my case. I tried to use github secrets, but it seems that it does not work. Here is the traceback in GitHub Actions: Creating test database for alias 'default'... /opt/hostedtoolcache/Python/3.11.4/x64/lib/python3.11/site-packages/django/db/backends/postgresql/base.py:405: RuntimeWarning: Normally Django will use a connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests).

Semantic-ui multiple How about customizing the display?
I have created a multi-selection dropdown box, but I don't want it to increase by one every time I click on it. I envisioned that it would display no more than three values, and if it did, it would display "4 for 10 selection", is there anything I can do to make this happen? I have tried this method but it gives me an error. //Customize the text that is displayed after multiple selections onLabelCreate: function(value, text) { if ($('.ui.dropdown').dropdown('get value').length > 3) { return '4 of 6 selected'; } } -

toggle table row based on unchecked checkbox
Not super familiar with frontend, but I have 4 checkboxes I'm using to filter table data. Any number of them can be selected at once. What I want to accomplish: get all unchecked boxes if no boxes are checked pass (meaning don't hide any rows) if a box is checked, for any box that is NOT checked, exclude the row associated with that unchecked box This is for a Django app and the table row id is being generated via database query. The table will have max 100 rows. Per the query I'm executing, any table row will be either: id="audio", id="video", id="writing", id="games" HTML: <div> <input type="checkbox" value="music" id="music_filter"> <input type="checkbox" value="video" id="video_filter"> <input type="checkbox" value="writing" id="writing_filter"> <input type="checkbox" value="games" id="games_filter"> </div> <table class="table"> <thead> <tr> <th>Col 1</th> <th>Col 2</th> </tr> </thead> {% for i in query_set %} <tbody> <tr id="{{i.media_type}}"> <td>{{some data}}</td> <td>{{some other data}}</td> </tr> </tbody> I have jQuery loaded via CDN in the html file and trying this: JQUERY/JS: $(document).ready(function(){ $('#music_filter', '#video_filter', '#writing_filter', '#games_filter').on('click',function(){ var notChecked = $("input:checkbox:not(:checked)"); if (notChecked.length > 0) { for (let i = 0; i < notChecked.length; i++) { $('#i').toggle(); }; }; }); }); A little help to see my mistake(s)? Thanks! -

Add field in swagger ui using drf-yasg
My code is hosted here. It uses drf-yasg, jwt and the django rest framework. I am trying to set up a patch method to have the user edit his task.

How to change related object when creating object in DRF
I want to change is_available field in Book object when reservation is being create. I found a way which I am pasting here, but this digging in request looks messy, so as it often is with so mature frameworks as drf there are probably better ways to do that. So I have serializer.py class BookSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = BookModel fields = ["number", "title", "author", "is_available"] class ReservationSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = ReservationModel fields = ["reserved_by", "book", "started_at", "valid_until"] And views.py class BookViewSet(viewsets.ModelViewSet): queryset = BookModel.objects.all() serializer_class = BookSerializer permission_classess = [] class ReservationViewSet(viewsets.ModelViewSet): queryset = ReservationModel.objects.all() serializer_class = ReservationSerializer permission_classess = [] def perform_create(self, request, *args, **kwargs): super().perform_create(request, *args, **kwargs) book = BookModel.objects.get(pk=request.data.serializer.instance.book_id) book.is_available = False book.save() I posted what I did, Please teach me do it better - proper way -
How can I assert that a pdf file was returned in python?

Specifically, this: status.HTTP_200_OK, 'application/pdf' I've seen a lot of posts about reading or opening files, but I just need to make sure it was in fact a pdf (file) that was returned. How can I set my mock up so that I can assert a pdf (file) was returned? -
How to attach HTMX parameters to a django input form
I am trying to implement an HTMX autosearch function to an input created by a django form. When I inspect the element on the page, the htmx tags are all present. However, the htmx never intializes and it never goes to the views endpoint. The code for the django input form is as follows: widget_attrs_nha_autosearch = { 'class': 'form-control', 'data-user-entry': 1, 'disabled': value.get('read_only'), 'hx-post': "{% url 'ng_django_pmp:nha-autosearch' %}", 'hx-target': '#results', 'hx-trigger': "keyup changed delay:500ms" } if value.get('label') == 'nha_override': self.fields[field] = forms.CharField( initial=value.get('default', ''), label=value.get('label'), max_length=value.get('max_length'), required=required, widget=forms.TextInput(attrs=widget_attrs_nha_autosearch), validators=value.get('validators', [])) When I attempt to create the htmx code on its own in html, it works just fine. However, I need the code to be created in this manner in order to properly trigger something on the backend. The HTMX code on its own is as follows: {% csrf_token %} <div class="d-flex justify-content-end mb-4"> <input type="input" hx-post="{% url 'ng_django_pmp:nha-autosearch' %}" hx-target='#results' hx-trigger="keyup changed delay:500ms" name="search" class="d-flex flex-grow-1 flex-column p-3 border border-secondary rounded m-2" style="overflow: auto; min-width: 0; min-height: 0" placeholder="" id='id_nha_override' /> </div> <div id="results"></div> Am I missing something? -

I have a question about generic view in Django's tutorial example
In the “Writing your first Django app, part 4” of the tutorial of Django documentation, there is example of using generic view like blow ; File name : polls/views.py class IndexView(generic.ListView): template_name = "polls/index.html" context_object_name = "latest_question_list" def get_queryset(self): """Return the last five published questions.""" return Question.objects.order_by("-pub_date")[:5] class DetailView(generic.DetailView): model = Question template_name = "polls/detail.html" class ResultsView(generic.DetailView): model = Question template_name = "polls/results.html"` Q1 .in “class IndexView”, where is the “latest_question_list” defined? Is it the return value of “get_queryset” function? If so, how can I find the relationship between “latest_question_list”and “get_queryset” function? There is not any clue. Q2.there is a explanation in the tutorial like so: In previous parts of the tutorial, the templates have been provided with a context that contains the question and latest_question_list context variables. For DetailView the question variable is provided automatically – since we’re using a Django model (Question), Django is able to determine an appropriate name for the context variable. However, for ListView, the automatically generated context variable is question_list. To override this we provide the context_object_name attribute, specifying that we want to use latest_question_list instead. My question is that, it said the question variable is provided automatically for DetailVIew. what does the “question” … -

What do you suggest that I do in order to deploy it to the Railway hosting: Deploy it to Railway using the complete Docker Compose project Deploy the React frontend, also deploy the Django/Python backend and also deploy the Postgres project Deploy just the frontend and backend, and use some sort of Postgres service that Railway could have I don't know which approach to take and which is viable. -
How can I exclude a subclass (or subclasses) of pages from Wagtail's search functionality?
I'm creating a blog site for a friend and there are certain page models that I would like to be excluded from users' searches. These models are BlogIndexPage and ThankYouPage. Both of these models subclass wagtail.models.Page. I want to have control over how these pages are visited and therefore don't want links for them to show up in search results if users search—for example—thank or blog. For context, this is the search view function: def search(request): search_query = request.GET.get("query", None) page = request.GET.get("page", 1) # Search if search_query: search_results = ( Page.objects.live().order_by("-first_published_at").search(search_query) ) query = Query.get(search_query) # Record hit query.add_hit() else: search_results = Page.objects.none() # etc... I've tried the two solutions suggested in this other thread and a third solution I found in the documentation, but they did not solve my problem. Specifically I tried the following: class ThankYouPage(Page): ... # Method One: @classmethod def get_indexed_objects(cls): return cls.objects.none() # Method Two: def get_indexed_instance(self): return None # Method Three: search_fields = [] I ran the update_index management command after each change. In the Django shell, I get the following behavior: >>> from wagtail.models import Page >>> from apps.contact.models import ThankYouPage >>> >>> Page.objects.all().search("thank") <SearchResults [<Page: Thank You Page>]> >>> >>> ThankYouPage.objects.all().search("thank") … -
How to define file path in a view method in django views.py
I need to read a CSV file in my view method. This is my view method in views.py in django project: def myfile(request): csv_fp = open('file.csv', 'r') reader = csv.DictReader(csv_fp) headers = [col for col in reader.fieldnames] out = [row for row in reader] return render(request, 'myfile.html', {'data' : out, 'headers' : headers}) This is in my urls.py: path('myfile/', views.myfile, name='myfile'), My django version is: 3.2.2 I tried many ways to open file in csv_fp = open('file.csv', 'r'). I used the below ways in my views.py and non of them worked: my file in the static directory: csv_fp = open('static/file.csv' , 'r') # not working csv_fp = open('file.csv' , 'r') # not working I added the below lines in my views.py and it didn't work as well: import csv, os from pathlib import Path BASE_DIR = Path(__file__).resolve().parent.parent STATIC_ROOT = os.path.join(BASE_DIR, 'static') file_path = os.path.join(STATIC_ROOT, 'file.csv') csv_fp = open(file_path , 'r') This is the error message: Exception Location: /home/djangoir/virtualenv/project/3.7/lib/python3.7/site-packages/django/template/loader.py, line 19, in get_template The point is I don't want to generate a model for the database and import CSV file into the database. I just need somehow read the file and export its data in a dictionary in the render method.
