Django How can I repeat a block within a template
My Django base template looks like this: #base.html <title>{% block title %} My Default Title {% endblock title %}</title> <meta property="og:title" content="{% block og_title %} My Default Title {% endblock og_title %}"> Then if I'd like to override the default title for specific page: #page.html {% extends "base.html" %} {% block title %} My page Title {% endblock title %} {% block og_title %} My page Title {% endblock _ogtitle %} How can I set the base.html block title once (like a variable) and use across my document? Then, if I need, I override the title once in the page.html and it gets populated across? -

About project - Django Rest API django==3.2.2 djangorestframework==3.12.4 I need to implement authentication in Django, including the social auth, permission at the role level. I am referencing the django doc https://www.django-rest-framework.org/api-guide/authentication/ But, I am confused when it says use third party library - Questions - Does Django rest framework does not provide auth and social auth?

Empty AJAX PUT request body; Django Rest API
I'm mimicking StackOverflow's template of voting on a Question/Answer. Upon clicking an upvote/downvote button, a PUT request is sent to the API. However, DRF doesn't find any data attached to the request body as request.data == {} in the respective view. How should I go fixing the client API call or the API itself for there to be a request body? vote_button.addEventListener("click", function(event) { voted_post = this.id.split("_") const _question = voted_post[0]; q_id = _question[_question.length - 1] vote = voted_post[-1] const headers = new Headers({ "Accept": "application/json", "Content-Type": "application/json", "X-CSRFToken": csrftoken }); const request = new Request( `http://localhost:8000/api/v1/questions/${q_id}/`, { "method": "put", "headers": headers, "body": JSON.stringify({ "vote": vote }) } ); fetch(request).then((response) => { if (response.ok) { return response.json() } }).then((data) => { let vote_tally = document.getElementById(`question${q_id}_tally`); vote_tally.textContent = data['vote_tally'] }) REST_FRAMEWORK = { 'TEST_REQUEST_DEFAULT_FORMAT': 'json', 'DEFAULT_PARSER_CLASSES': [ 'rest_framework.parsers.JSONParser' ], 'DEFAULT_RENDERER_CLASSES': [ 'rest_framework.renderers.JSONRenderer' ], 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated' ], 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.SessionAuthentication' ], 'DEFAULT_THROTTLE_CLASSES': [ 'rest_framework.throttling.ScopedRateThrottle' ], 'DEFAULT_THROTTLE_RATES': { 'voting': '5/minute' } } class UserQuestionVoteView(APIView): throttle_scope = "voting" def put(self, request, id): account = UserAccount.objects.get(user=request.user) question = get_object_or_404(Question, id=id) if account == question.user_account: return Response(data={ 'vote': "Cannot vote on your own question" }, status=400) try: stored_vote = QuestionVote.objects.get( account=account, question=question ) serializer = … -
How to store large JSON FILE data in django using models. ( using HTML, CSS, Javascript and Django)
I'm using Django as storage, and HTML, CSS for the frontend. So, I have successfully created models for Products, Categories, Carts, and Users. I can store data and fetch the data too but adding one row at a time is time-consuming. I have 2000 + data (Stored in .JSON) in one category (Since making an e-commerce website). So how, I will get rid out of it. What are the codes needed? -
Django default value in in input field
I need to set a placeholder/default value for the input field below (the first field in the form) I need to send the data ex_name.id in order to validate the form, which it does, but I want the information displayed in the field to be ex_name.exercise. I was able to accomplish this in the option fields (fields 2 and 3), but not for the input field. If I make the input field an option field, it doesn't send the data when I submit it because the field is readonly and it has to stay readonly. value must be ex_name.id/ex_name.pk, but I don't want to display a number to the end user. How to I display different text there while still retaining value="{{ex_name.id}}"? <div class="form-group col-lg-4 col-md-6 col-sm-12"> <form action="" method="post"> {% csrf_token %} <label for="exercise">Exercise</label> <input class="form-control" id="id_exercise" type="text" name="exercise" value="{{ex_name.id}}" required="" readonly> <label for="unit">Select Unit</label> <select class="form-control" id="id_unit" name="unit" value=""> {% for unit in unit_list %} <option value="{{unit.id}}">{{unit.unit_name}}</option> {% endfor %} </select> <label for="location">Location</label> <select class="form-control" id="id_location" name="location" value=""> {% for loc in locations %} <option value="{{loc.id}}">{{loc.location}}</option> {% endfor %} </select> <label for="quantity">Pax</label> <input class="form-control" id="id_quantity" type="text" name="quantity" value="" required=""> <input class="btn btn-primary mt-3" type="submit" value="Submit"> </form> </div> -
Updating records within a modal
We have taken on a project where the front end admin dashboard has been created using Bootstrap Modals. When we go to update a record from the ASP modal we have used JSON outputs and JQuery to populate the data within the form, as from what we found this could not be done by Django alone. The issue we have is that we can add new records using the populated JSON data but I cannot edit existing records. Even though JQUERY and JSON brings the correct data when we click submit it cannot associate to the record within the database. How could we update the correct record? One other method we tried was passing the ID (related to the booking) through the URL but this kept redirecting the page and not staying on the modal. Just so I don't add to much, below is the related code to the issue. I am not great with programming so hope this makes some sense what we are trying to achieve, thanks in advance for any help we can get with this issue.

Any way to translate a field in my django model already downloaded to my PostgreSQL database through a fixture?
I've been reading about internationalization/location in Django and have been stuck in a deadlock-kinda situation: I need to translate a charfield from English to Spanish, but such data is uploaded to my proyect implementing a fixture. I can't use the native tools from django.utils.translations since this data isn't recognized by the makemessages command. Also, I've found that making a custom django.po message file for such uploaded strings is a bad practice: https://code.djangoproject.com/ticket/6952. On the other hand I found the package django-modeltranslation (https://django-modeltranslation.readthedocs.io/en/latest/index.html) but this doesn't solve my issue since I need the string in my charfield to be a customized locale, I must provide specific translations for each as a requirement and I only see that this tool can only translate based on the standard localizations. Any ideas? Here is my model for further information: class Triague_Question(models.Model): question_text = models.CharField(_("question"), max_length=255) is_critical = models.BooleanField(_("is a critical question"), default=False) is_medical = models.BooleanField(_("is a medical question"), default=False) -

link multiple database models in django by unrelated fields
In sql if there are two table which have fields that have data with resemblance but do not have connection together you can links them up like this select tab1.name, tab1.gender, tab1.occupation, tab2.location , tab2.biz_time ,tab3.address from staffdata tab1, sales tab2, address tab3 where tab1.user_id=tab2.user_id and tab3.location_id=tab2.location_id this would link them up to produce results from the 3 tables I have tried subquery, annotate with values but was getting wrong result this is what i have tried code_subquery = SalesRecord.objects.filter(staff__username__iexact=request.user, user_id=OuterRef('user_id')) timetablevalues= StaffData.objects.filter(staff=request.user, user_id=Subquery( code_subquery.values( 'location', 'biz_time', 'item')))\ .values('name','gender', 'location', 'biz_time', 'item') Although this is for 2 tables but I might do that of 3 tables later on Please how can I go about it -
How to filter a list JSONField exactly?
I have a model that essentialy boils down to this: class Model: json_field = ArrayField() Where json_field is essentially a list of strings. So let's say I have two Model objects ModelA and ModelB that have their json_field as ["1","2","3"]and ["1","2","4"] respectively. How can I filter to the json_field exactly? Specifically: What is the search value? What is the query that filters by the search value? value = ["1","2","3"] # Doesn't work value = "1","2","3" # Also doesn't work # Not even sure if this is the correct approach Model.objects.filter(json_field__iexact=value) I'm actually using django-filter to manage this search function for a DRF backend. (e.g. /api/v1/models/?json_field=) Unfortunately, there doesn't seem to be an ArrayFilter or a JSONFilter so this is what I'm working with: class ModelFilter(django_filter.FilterSet): class Meta: model = Model field = "json_field" # Not even sure if this should be a CharFilter json_field = django_filters.CharFilter(method="json_field_filter") def json_field_filter(self, queryset, name, value): return queryset.filter(json_field__iexact=value) # doesn't work where value = ["1","2","3"] # also doesn't work where value = "1","2","3" I can find solutions online (from which I've worked to the above) for dictionaries but nothing for lists. Would appreciate any help/pointers. -

Optimize a Django query where it uses prefetch_related on a select_related
I'm trying to figure out how to optimize a Django query. I have an queryset that contains a foreign key to exercises. That table makes ManyToMany references to a number of other tables. If selecting exercises, I'd use prefetch_related to include them in the query, but I can't figure out how to do that in this case, since I'm doing it from a different table. Currently, it's being selected as super().get_queryset(request).select_related('exercise') But I can't figure out how to attach prefetch_related to that. Looking at SO, I found a solution that led me to this: return super().get_queryset(request).select_related( Prefetch( 'exercise', queryset=Exercise.objects.prefetch_related('equipments', 'inuries') ) ) But it fails with 'Prefetch' object has no attribute 'split', which I traced through the source, and it looks like select_related can't work with Prefetch. -
Need help making 1000's requests as fast as possible., python, django
I'm deep in the middle of coding a full web application in Django, but am venturing into new territory trying to send 1000's of API Trading Requests to an exchange as fast as possible. I want it so that each time it iterates through the loop ( each bot ), it sends the trading signal to the exchange, collects some data from the exchange and logs all the data in the databse. But since it has to wait each time it sends or receives data to/from the exchange, I am trying to figure out how to make the code asynchronus. So that it would get to each waiting point then start the next loop, and start sending the next signal. Then come back and finish collecting the data and saving it to the databse when it can. Because obviously if it has to wait each time on 1000's of bot's then it will take ages. I'm getting confused trying to figure it out online and wondered if someone could help/answer some things for me. I also wondered that since I'm trying to run the code async and the variable names are the same in each iteration of the loop, would …
