Running django web app over a web path in a sandbox
At the place where I work we have the option to deploy applications through a sandbox. With that a problem arises and that is that for each application running we have a web path, for example: domain.com/path/of/app_django/. With that base path I can access the main view of my application (0.0.0.0:8080/ >> domain.com/path/of/app_django/) however when trying to access other views django uses the main domain, for example domain.com/my_url instead of being domain.com/path/of/app_django/my_url. What can I do to fix this? -
Reduction of queries in ManyToMany field with prefetch_related
I want to reduce further the number of queries. I used prefetch_related decreasing the number of queries. I was wondering if it is possible to reduce to one query. Please let me show the code involved: I have a view with prefetch_related: class BenefitList(generics.ListAPIView): serializer_class = BenefitGetSerializer def get_queryset(self): queryset = Benefit.objects.all() queryset = queryset.filter(deleted=False) qs= queryset.prefetch_related('nearest_first_nations__reserve_id') return qs I have the models used by the serializers. In here, it is important to notice the hybrid property name which I want to display along with reserve_id and reserve_distance: benefit.py: class IndianReserveBandDistance(models.Model): reserve_id = models.ForeignKey(IndianReserveBandName, on_delete=models.SET_NULL, db_column="reserve_id", null=True) reserve_distance = models.DecimalField(max_digits=16, decimal_places=4, blank=False, null=False) @property def name(self): return self.reserve_id.name class Benefit(models.Model): banefit_name = models.TextField(blank=True, null=True) nearest_first_nations = models.ManyToManyField(IndianReserveBandDistance, db_column="nearest_first_nations", blank=True, null=True) Name field is obtained in the model IndianReserveBandName. indian_reserve_band_name.py: class IndianReserveBandName(models.Model): ID_FIELD = 'CLAB_ID' NAME_FIELD = 'BAND_NAME' name = models.CharField(max_length=127) band_number = models.IntegerField(null=True) Then, the main serializer using BenefitIndianReserveBandSerializer to obtain the fields reserve_id, reserve_distance and name: get.py: class BenefitGetSerializer(serializers.ModelSerializer): nearest_first_nations = BenefitIndianReserveBandSerializer(many=True) The serializer to obtain the mentioned fields: distance.py: class BenefitIndianReserveBandSerializer(serializers.ModelSerializer): class Meta: model = IndianReserveBandDistance fields = ('reserve_id', 'reserve_distance', 'name') The above is resulting in two queries which I would like to be one: SELECT ("benefit_nearest_first_nations"."benefit_id") AS … -
Django Channels + Vue + Daphne + Google App engine flex app won't start after deployment
The app loads blank screen, and after inspecting the Network tab in browser I see that only main.css and main.js are requested, no chunk-some_id.js or css files. On top of that the main css and js cause a message in browser console Refused to apply style from 'my_site.appspot.com/static/vue/css/main.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

form_valid method not called if post method not overrided
I have a blog that is composed by user's posts and post's comments. In my UpdateView, the model points to Post, so I can show the post in the template.

How to read byte strings generated by marshall on the jquery side?
On the Django server side, I form a response: def index(request): if request.method == 'POST': ... url = reverse(settlement_create, args=[settlement_id]) return HttpResponse(marshal.dumps({'url': url}), content_type="application/json") , where url=/settlement/154/create. jQuery cannot decode the byte string correctly and it turns out {� url� /settlement/154/create0. $.ajax({ type : 'POST', url : url, data : {'text': city_info}, success : function(response){ $("#city-href").attr('href', response['url']); }, error : function(response){ console.log(response) } }); If you use a regular json library instead of marshal, then everything works fine. Do you have any ideas? -

removing added django application from a database
I just posted another question: Django error on deleting a user in the admin interface But realized in that question the project /models it is complaining about I am going a different direction with. So I was curious how I can I just remove a project from the database. i.e. a whole folder under my django application? I will be redoing it anyway and I want my deployed application from the earlier question to keep working along. Is it just a matter of removing all the data in models.py and then doing a new migration? -

Download all the processed files generated on the fly as zip file on client side (without saving processed files on Server/Database) in Django Python
I want to download all the processed files generated in a program as a zip file on client system on the fly without storing them on the server/database side. I am working on Django framework. The idea is to take multiple files as input from the user, perform some processing on excel files and then download those files as a single zipfile (on the fly) at the client end without storing them on server To achieve this, what I did is: **In my views.py file:** from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt import zipfile import pandas as pd import io # creating a zip file object outside any function so that its accessible to all the functions in the views.py file (**Not sure if this is the right way of doing it**) zipObj = ZipFile('sample.zip', 'w') # This function identifies if the file is excel def myfiletype(fname): filename = fname # Get file extension file_ext = filename.split(".")[-1] # check if extension matches type of file we expect: if file_ext.lower() in ("xls", "xlsx"): return "excel" return "unrecognized" @csrf_exempt def files_processing(request): if request.method == "POST": files = request.FILES.getlist('file') # process each file: for file in files: if myfiletype(str(file)) == 'excel': excel_processor(file) … -

Module not found error in Python script running as a Windows Service
I have a Django "learning project" which hosts a very simple web site, with waitress providing the WSGI server. The project performs as expected when I execute the calling script from the command line. From here I'm trying to set up the scaffolding to have it run as a Windows Service. I installed pywin32 and servicemanager to my virtual environment, and -- later on, trying to resolve an error -- also installed them to my "real" Python instance on the machine. Despite this, I keep getting a ModuleNotFoundError error, citing servicemanager, when I try to start the created service: This Python script I'm using; it is based on a template script I found here. import win32serviceutil import win32service import win32event import servicemanager import socket from waitress import serve from django_project.wsgi import application class AppServerSvc (win32serviceutil.ServiceFramework): _svc_name_ = "PagesService" _svc_display_name_ = "Pages Service" def __init__(self,args): win32serviceutil.ServiceFramework.__init__(self,args) self.hWaitStop = win32event.CreateEvent(None,0,0,None) socket.setdefaulttimeout(60) def SvcStop(self): self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING) win32event.SetEvent(self.hWaitStop) def SvcDoRun(self): servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE, servicemanager.PYS_SERVICE_STARTED, (self._svc_name_,'')) self.main() def main(self): serve(application, port='8000') if __name__ == '__main__': win32serviceutil.HandleCommandLine(AppServerSvc) As noted above I've installed servicemanager to both the virtual environment and the "real" environment, I've followed the classic Roy request and rebooted the machine just to be sure. Here's the requirements.txt … -
Trying to Debug Dynamic Forms in Django - logging SQL
Context: I've recently taken on Web Development responsibilities at my job. I'm not 100% familiar with Django or our codebase yet. Our staff intranet has dynamic forms for different accident reports. We have a non-employee accident report that functions perfectly, and an employee accident form that is currently not functioning. The code is nearly identical less a few different fields for each. When the form is submitted, the page will provide a summary of the info you entered to be approved for publication. This works on the non-employee form, but not on the employee form. When I submit the bugged form, the form data exists in the payload and the post request returns a 200 response. At this point we are thinking that it is a database issue, but there isn't any debugging implemented. We are trying to implement some debugging, but I can't get anything to display in the console, though I do think I am pretty confused. IMPORTANT NOTE: We are on a super outdated version of django: 1.11 This is what I have in my settings.py file. Everything I have found and read online says that this should print SQL statements to the console. But I'm not … -
Case-insensitive collation for django field
After upgrading to django 4.2, I changed an email field from CIText into TestField with db collation. However, after the update the field does not seem to be case insensitive (for example querying by email "example@example.com" returns an instance and querying by email "Example@example.com" does not) Here's what I did: Created a new db collation for CI operations = [ CreateCollation( name="case_insensitive", provider="icu", locale="und-u-ks-level2", deterministic=False, ) ] Changed the field from a CITextField to a TextField with the new collation and applied this change's migration email = models.TextField( max_length=255, db_index=True, db_collation="case_insensitive", ) I am using Postgres 12 What else is needed to define a field as a CI? Thanks!
