Django and Nginx are redirecting in response
I have a project with Django and it is running using Nginx, gunicorn. And the URL of the Project is https://myweb/myapp(this I got from our IT). The problem is if I type my URL https://myweb/myapp/ it redirects to https://myweb/login (which doesn't exist and I got a 404 error), but actually, I want to have https://myweb/myapp/login, if I add to the URL /myapp/ it works for the first time, but it redirects again to https://myweb/dashboard/, again I want to have https://myweb/myapp/dashboard/, and so on. How can I properly redirect? or should say how to prevent Django from removing the prefix URL? the Nginx file: server { listen 127.0.0.1:100; server_name hammbwdsc02; client_max_body_size 4G; access_log /home/webapps/culturecrawler/logs/nginx-access.log; error_log /home/webapps/culturecrawler/logs/nginx-error.log; location /static/ { alias /home/webapps/culturecrawler/culture_crawler/static/; } location /media/ { alias /home/webapps/culturecrawler/culture_crawler/media/; } location /{ proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; proxy_set_header Host $http_host; proxy_redirect off; proxy_buffering on; proxy_buffer_size 128k; proxy_buffers 4 256k; proxy_busy_buffers_size 256k; proxy_connect_timeout 300s; proxy_read_timeout 300s; if (!-f $request_filename) { proxy_pass http://culture_crawler_app; break; } } # Error pages error_page 500 502 503 504 /500.html; location = /404.html { root /home/webapps/culturecrawler/culture_crawler/templates/; } and the gnicorn file: #!/bin/bash NAME="culture-crawler" # Name of the application DJANGODIR=/home/webapps/culturecrawler/culture_crawler # Django project directory SOCKFILE=/home/webapps/culturecrawler/run/gunicorn.sock # we will communicte using … -
Creating a double log in system for department and user
I'm using django to create an webapp. I have been asked if I can look at creating a sort of double log in system. For example: A nurse on the ward will open up my webapp and will be met with a login page for their ward. So all nurses on that ward will have that generic log in. Once they've logged in they will be met with a second login page where they can enter their normal user credentials that only they know. I'm quite stuck at how to achieve this currently - or if someone could suggest an alternative method I'd be grateful! -

How do I add <a> tags to a Django HTML Email template?
I'm trying to set up a view to reset passwords. The HTML email template works fine, until I add a anchor tag which causes the emails to no longer be sent.

GCP App Engine w/Django: big pandas load in views is causing server error
One of my page views in GCP App Engine (standard) is failing to load. I've determined that the issue occurs when Django temporarily loads a large pandas dataframe from cache (30mb). This is necessary in order for my charts to grab a subset of the data for charts before page rendering (it is not being injected into the html at all). def myView(request): baseTable = cache.get("somecachekey") #issue is here chartDiv = makeChart(baseTable) return render(request, template_name = 'myView.html', context = {'chart' : chartDiv}) Interestingly, there are no server errors. The logs seem fine. Also, this view works successfully when I am locally hosting Django on my laptop. Any advice here? -

Customized Password Reset URL for Django Rest API Password Reset

How do I generate SECRET_KEY in django and postgresql database for a .env file?
A bit confusing to me is I am working on a project with a previously generated key - like so: SECRET_KEY='1x8n9Xj4UNw8T2PgIiaircPBcZ5z9u0TTBivRbeTMbbRsiNM1VUjWlkP1mDZy8o11csfee*^5jvpGsH41VYVUAx8jE110ashdjkrkGBIjJRQ1SxU8irV6mcNz-3rQ1RDWiDv1WqmSfVtUX4kYymodEEZkeKNH4mQUlHsqdVX2ZAJ4BQaYmQOzKls' but its longer that the one I generated which is more like so: SECRET_KEY='te1we2*&v_&!9p1jhl7-aa@z$mlrb#v=2%xuyt%h([(ew@3z0^' using this command python manage.py shell -c 'from django.core.management import utils; print(utils.get_random_secret_key())' And in what instances would the KEY not be enclosed with quotes('') in the .env file. I know the procedure involved in securing the secrets, my confusion comes with the structure of the first SECRET_KEY which makes me think am doing something the wrong way. -
Error: unknown tag from YAML in DRF generated openapi schema
I have a data model in Django that gets serialized with Django Rest Framework. To document this API made with Django Rest Framework I want to use DRF's option to automatically create an openapi schema that then generates a redoc documentation. The problem that I have is that the Django decimal field creates a datatype that YAML doesn't seem to understand causing Error: unknown tag !<tag:yaml.org,2002:python/object/apply:decimal.Decimal> The block where the last line that generates the error looks like type: string format: decimal multipleOf: 0.01 maximum: 100000000 minimum: !!python/object/apply:decimal.Decimal I have found some posts touching similar errors here and here but they don't fix my problem and also seem somewhat unrelated to my problem as they focus on solving the same error message but the error originates from another problem. I have tried the approach with adding the unknown tag to the settings.json file but without success. However I am also not completely sure how the content of "yaml.customTags": [...] should exactly look like in this case. -
django - cargar archivo csv en la base de datos
I created a view where I have a form, I have a input type="file" to load a csv file, but my code takes a long time to process the file, to process a file of 1000 records it takes about 10 minutes, I have analyzed the I code and it takes too long in the "for" loop, insert into the database is not delayed because I use "bulk_create", how can I improve it? this is my code: class AsignacionCreateView(CreateView): model=AsignacionContact form_class=AsignacionForm template_name='gestionAsignacion/asignacion_contact.html' success_url = reverse_lazy('gestionAsignacion:asignacion_contact') def form_valid(self, form): isvalid = super().form_valid(form) csv_file = self.request.FILES['file'] data=codecs.iterdecode(csv_file, 'utf-8') data = csv.reader(data, delimiter=",") next(data) asignaciones = [] for row in data: print('inicio de for') asignacion = AsignacionSur( idasignacion=AsignacionContact.objects.get(id=self.object.pk), producto=row[0], contrato=row[1], nombre_suscriptor=row[2], tipo_servicio=row[3], total_deuda=row[4], corriente_no_vencida_actual=row[5], corrente_vencida=row[6], total_deuda_corriente=row[7], cuota_minima_agente=row[8], politica_surtigas=row[9], categoria=row[10], estrato=row[11], ref_anio=row[12], historico_ref=row[12], ciclo=row[14], medidor=row[15], lectura=row[16], plan_acuerdo=row[17], descripcion_barrio=row[18], direccion=row[19], dias_deuda=row[20] ) asignaciones.append(asignacion) if len(asignaciones) > 5000: AsignacionSurtigas.objects.bulk_create(asignaciones) asignaciones = [] if asignaciones: AsignacionSur.objects.bulk_create(asignaciones) return isvalid This part of the code takes too long: for row in data: asignacion = AsignacionSur( idasignacion=AsignacionContact.objects.get(id=self.object.pk), producto=row[0], contrato=row[1], nombre_suscriptor=row[2], tipo_servicio=row[3], total_deuda=row[4], corriente_no_vencida_actual=row[5], corrente_vencida=row[6], total_deuda_corriente=row[7], cuota_minima_agente=row[8], politica_surtigas=row[9], categoria=row[10], estrato=row[11], ref_anio=row[12], historico_ref=row[12], ciclo=row[14], medidor=row[15], lectura=row[16], plan_acuerdo=row[17], descripcion_barrio=row[18], direccion=row[19], dias_deuda=row[20] ) -
I want to customize the error message for a login api to django rest framework simple jwt

Form_valid not redirecting to success page
I have a class base view which renders a form. When the form is correctly filled, I want to redirect to a success url, but couldn't find a way to do that. Every thing I tried just reloads the form page without redirecting. Before that I had a function based view and it was correctly redirecting using : return HttpResponseRedirect(reverse('scripts:results', args=(self.script_id,))) I tried to define a success_url, override get_success_url and form_valid but each time I just have a refreshed form (code below). success_url : success_url = reverse('scripts:data_input', args=(self.script_id,)) get_success_url : def get_success_url(self): return reverse('scripts:data_input', args=(self.script_id,)) form_valid def form_valid(self, form): return HttpResponseRedirect(reverse('scripts:results', args=(self.script_id,))) I've tried changing the view to render, and it seems to work for the views that don't have any arguments, so maybe the problem is coming from there but I couldn't find how to solve it. If needed, here is my urls.py : app_name = 'scripts' urlpatterns = [ path('', views.ScriptsView.as_view(), name='scripts'), path('<int:script_id>/data/', views.DataInputView.as_view(), name='data_input'), path('<int:script_id>/results/', views.results, name='results'), ] And my view : class DataInputView(FormView): form_class = ScriptInputForm initial = {'key': 'value'} template_name = 'scripts/data_entry.html' def setup(self, request, *args, **kwargs): self.script_id = kwargs['script_id'] self.script = Script.objects.get(pk=self.script_id) self.module = Script.get_script(self.script) return super().setup(request, *args, **kwargs) def form_valid(self, form): return HttpResponseRedirect(reverse('scripts:results', … -
Django: serving static files for production

Here is the code class PostPage(BasePage): serializer_class = "blog.serializers.PostPageSerializer" header_image = models.ForeignKey( "wagtailimages.Image", null=True, blank=True, on_delete=models.SET_NULL, related_name="+", ) body = StreamField(BodyBlock(), blank=True) tags = ClusterTaggableManager(through="blog.PostPageTag", blank=True) content_panels = Page.content_panels + [ ImageChooserPanel("header_image"), InlinePanel("categories", label="category"), FieldPanel("tags"), StreamFieldPanel("body"), ] search_fields = Page.search_fields + [ index.SearchField('title'), index.SearchField('body'), ] api_fields = ( APIField( "header_image_url", serializer=ImageRenditionField("max-1000x800", source="header_image"), ), "body", APIField("owner"), APIField("api_categories", serializer=CategoryField(source="categories")),#check if categories retrieved APIField("api_tags", serializer=TagField(source="tags")), #APIField("pub_date",serializer=DateTimeField(format="%d %B %Y", source="first_published_at")), ) def get_preview_url(self, token): return urllib.parse.urljoin(self.get_client_root_url(), f"post/{self.pk}/" + "?" + urllib.parse.urlencode({"content_type": self.get_content_type_str(), "token": token}), ) def serve(self, request, *args, **kwargs): return HttpResponseRedirect(urllib.parse.urljoin(self.get_client_root_url(), f"/post/{self.pk}") ) And here is the BasePage class which is being inherited in PostPage: class BasePage(HeadlessPreviewMixin, Page): serializer_class = None class Meta: abstract = True def get_component_data(self): if not self.serializer_class: raise Exception(f'serializer_class is not set {self.__class__.__name__}') serializer_class = import_string(self.serializer_class) return { 'page_type': self.__class__.__name__, 'page_content': serializer_class(self).data } def categories_list(self, context): categories = BlogCategory.objects.all() … -
MySQL to PostgreSQL migration converted camelCase columns to simple format. Leading to Column does not exist error in Django ORM
I migrated MySQL database to PostgreSQL using pgloader. I am using Django ORM to execute the queries. The database fields are defined in camel case but after the migration the postgres columns are replaced to normal format. e.g brochureName is changed to brochurename. This is causing "Column does not exist" error in the application. What is the best way to handle this issue? I have lots of columns and queries already defined at many instances.
