Django compressor isn't working on heroku
I'm using Django with the Django compressor package on heroku. To make the setup easier I'm using the official Django + Heroku package. My base.html template has the following include tag: {% include 'base/js.html' %} This file contains all JS files: {% load static %} {% load compress %} {% compress js %} <script src="{% static 'libs/jquery/dist/jquery.min.js' %}"></script> <script src="{% static 'libs/bootstrap/dist/js/bootstrap.bundle.min.js' %}"></script> # ... {% endcompress %} I've enabled COMPRESS_OFFLINE = True and my release task has the following command: python manage.py compress Since heroku does the collectstatic before running this command I've added another collectstatic command after the compress command. The first problem is that if I push my code with this settings, the JS just disappears. Event if I add normal html in the js.html file it's not displayed like it was never included. If I move the content from js.html to the base.html file I will get this error: OfflineGenerationError: You have offline compression enabled but key "37bfd22c7ae7d3c1ebae6f1f6cf17b892d51be333cd571cb6c1466d1291cd228" is missing from offline manifest. You may need to run "python manage.py compress". I've also tried running the compress command again but nothing happens. The error is still there. -
Django worker not handling oath replies correctly with daphne
Creating title for this question was tricky, so please forgive. I am trying to setup SSO with MicroSoft and Django. Found a promising plugin to handle this, but having some issues I think may be related to django / daphne more than the plugin itself. The plugin is designed to handle the callback from MS SSO, and there a django view that handles the response. Well, this is not working as expected. The question however is about the behavior of what I am seeing in the logs while troubleshooting. I can see the callback come in: worker logs: 2018-11-23 17:23:54,920 - DEBUG - worker - Dispatching message on http.request to channels.handler.ViewConsumer Bad Request: /microsoft/auth-callback/ daphne logs 2018-11-23 17:23:54,920 INFO "127.0.0.1" - - [23/Nov/2018:17:26:28 +0000] "POST /microsoft/auth-callback/ HTTP/1.1" 400 665 "https://login.microsoftonline.com/common/reprocess?ctx=****&sessionid=*******" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0" However, this is where it dies. The reply is supposed to have a payload containing the session state. However, while watching the django worker log, I restarted the django worker. While shutting down the workers, I see this appear in the logs: 2018-11-23 17:30:26,746 - INFO - worker - Shutdown signal received while idle, terminating immediately {'state': '****', 'session_state': '***'} This … -
How to test POST method using DRF and HyperlinkedModelSerializer serializer

Session being set but not persisted
Problem The django.contrib.auth.login function is succeeding, but the session does not seem to persist. Code I am creating my own set of functions to use with an AJAX client inside of my Django server. I have the following code in urls.py: from django.contrib.auth import authenticate, login from django.conf.urls import url from django.http import JsonResponse import json def auth_login(request): username = json.loads(request.body)['username'] password = json.loads(request.body)['password'] user = authenticate(request, username=username, password=password) if user is not None and user.is_active: login(request, user) return JsonResponse({}, status=200) else: return JsonResponse({}, status=400) urlpatterns = [ url(r'auth/login/', auth_login, name='login') ] Details As mentioned above, the call to login() succeeds. request.session is being set properly, and I can access if from within auth_login. On subsequent requests, request.session does not exist and django.contrib.auth.get_user returns AnonymousUser. (Possibly relevant) I am also using the seemingly-popular https://django-tenant-schemas.readthedocs.io/en/latest/. This urls.py file is in an application that is per-tenant, so the user is actually authenticating on tenantname.hostname.com/tenant/auth/login/. The tenant's django_session table is being set correctly. For each attempted login, I can see session_key, session_data, and expire_data. The cookie for tenantname.hostname.com is empty after attempted logins. I'm just out of ideas as to what other things I could try to lead me to a solution. Question(s) … -

Return Class based view from function based view

Django uploading to Amazon s3 with chunks
We're using the S3Boto3Storage to upload media files to our s3 storage on Amazon. This works pretty well. Since we're using Cloudflare as a "free" version we're limited to a maximum of 100MB per request. This is a big problem. Even the Enterprise plan is limited to 500MB. Is there a way to use a kind of "chunked uploads" to bypass the 100MB-per-request limit? model.py class Media(models.Model): name = models.CharField(max_length=100, null=True) file = models.FileField(upload_to=get_path) storage.py from storages.backends.s3boto3 import S3Boto3Storage class MediaStorage(S3Boto3Storage): location = 'media' file_overwrite = False views.py @api_view(['POST']) def upload_media(request): if request.method == 'POST': serializer = MediaSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) -

Save chinese character in Django SQLite model field & Displaying in Template
How do I save chinese characters in Django model fields and show this properly in the HTML template and django-admin? I would like to save chinese names into the database. They are only 3 characters long. If this is too complex, are there any workaround such as outputting the characters in image file and saving the characters as an image? I don't plan on manipulating the characters stored 'in-string', only saving and showing them on the template. Thank you. -
Django: Combining textbox and dropdown from values stored in database in Django forms
I've two models User and Company. I have created two custom forms from these models and showing in the same template for signup. Logic is like, if the company already exists in the database then it shouldn't create a new record in the Company but just assign the existing company to the user. Otherwise, create a new company and assign to the user. For the convenience, on the signup template, I want to show the dropdown with all the existing company names from the company table. So that either user can select the name from the list or write his own company. Following is my code files signup.html {{ company_info_form.company_name|as_crispy_field }} {{ company_info_form.company_address|as_crispy_field }} forms.py class CompanyInformationForm(ModelForm): company_name = forms.CharField(label = popover_html('Company Name', 'Company Name')) company_address = forms.CharField(label = popover_html('Company Address', 'Compnay Address')) class Meta: model = CompanyInformation fields = ( "company_name", "company_address" ) views.py (for GET request): form = RegistrationForm() company_info_form = CompanyInformationForm() args = {"form": form, "company_info_form": company_info_form} return render(request, "registration/signup.html", args) I assume I don't need to do many changes if I can make a combo of textbox and dropdown both. As I will read the value to apply the logic. P.S. Let me know if you … -
Site matching query problem with redirects app
I would like to use "redirects app" for redirect all paths from an old site to a new site. On my site I've already "sitemap framework" and "syndication feed framework". Without "redirects app" I don't have problems to see feeds page and sitemap page.

Using django.contrib.session with django.contrib.auth
I would like to use Django's session-based authentication. I have used the following page as an example: https://docs.djangoproject.com/en/2.1/topics/auth/default/#how-to-log-a-user-in. Specifically, my login view looks like this: def auth_login(request): username = json.loads(request.body)['username'] password = json.loads(request.body)['password'] user = authenticate(request, username=username, password=password) if user is not None and user.is_active: login(request, user) return JsonResponse({}, status=200) else: return JsonResponse({}, status=400) The only difference between this and the example from the link above is that there they suggest to redirect to a success page. My application is single-page so I'm making AJAX requests and returning JSON responses. This example does not set a session ID in the cookie for this site, however the request succeeds. If I make a subsequent request to a secure resource, I'm still getting a 403 error. This is my first Django project, so I'm likely forgetting something simple. Any thoughts? -
Django Templates and render() - How to access multiple values
Learning Django and I'm having an issue with accessing 2 different values. In views.py under def home(request, I've added a list of 2 dictionary objects and passed it through under context. It works perfectly, I'm about to for loop over the dictionary in my front_page.html template, but I've also added a simple if title variable which only works if I place {'title': 'Competitive'} before the variable context. from django.shortcuts import render # Create your views here. owl = [ { 'title': 'Competitive' }, { 'Team': 'Dynasty', 'Location': 'Souel Korea', 'Colors': 'Black & Gold', }, { 'Team': 'OutLaws', 'Location': 'Houston', 'Colors': 'Green & Black', } ] def home(request): context = { "owl": owl } return render(request, 'overwatch_main_app/front_page.html', context, {'title': 'Competitive') def second(request): return render(request, 'overwatch_main_app/about.html', {'title': 'Boom'}) I've even tried comp = {'title': 'Competitive'}, and placing comp into the render(). It only works when I place comp, or {'title': 'Competitive'}before content and then content doesn't work. return render(request, 'overwatch_main_app/front_page.html', comp, context) return render(request, 'overwatch_main_app/front_page.html', {'title': Competitive'} , context) How can I pass more than 1 value of dictionaries to my template via render() front_page.html {% extends 'overwatch_main_app/base.html' %} {% block content %} <h1> OverWatch</h1> {% for o in owl %} <p>{{o.Team}}</p> … -

Using different database values for BooleanField in Django
I am converting an old MS Access database to a Django-based website. I've converted the data to a SQLite database, and automatically generated the models using inspectdb (which worked as well as could be expected). It seems that MS Access stores boolean values as -1 for True and 0 for False. Rather than modify the database (it is a lot of tables!) I'm trying to subclass models.BooleanField, as follows: class MsAccessBooleanField(models.BooleanField): def from_db_value(self, value, expression, connection): if value == -1: return True if value == 0: return False def to_python(self, value): if value == -1: return True if value == 0: return False def get_prep_value(self, value): if value == True: return -1 if value == False: return 0 return None def get_db_prep_value(self, value, connection, prepared=False): if value == True: return -1 if value == False: return 0 return None When I view entries via the Admin interface, this seems to work (-1 values appear as Yes in the dropdown; 0 values as No). However (this is the problem), when modifying the value and saving, I can only save as No or Unknown (selecting Yes produces a message that no value has been specified).

Django admin sending a message based on inline formset
I'm writing a reservation program using the Django admin. The program will warn the user (via Django messages) when the total nights for all room changes is greater than the total nights for the reservation. So if a reservation is for 7 nights and the user enters the guest into room "A" for 4 nights and room "B" for 4 nights (totaling 8 nights) the user will see a warning. The reason for a warning and not a simple form error is that a group can have multiple rooms per night, which would make it possible for the above to occur. The code works (below is the relevant pieces). warn_if_rc_nights_gt_reservation_nights(), which houses the logic to warn the user, operates on the form instance (when the form is only being rendered) or the raw request.POST variables (when the form is being saved/POSTed) in order to tally up the total nights for room changes and reservations. I'm OK with using the form instance to tally the total nights, but I have a problem with the raw POST variables, since it's more error-prone (POST variables are not clean() yet) and un-Django-like. I'd rather use a built-in class method or function to accomplish this. … -

A remember me key is also added in loginform Views.py login view @csrf_protect @never_cache def loginremember(request): if request.method == "POST": form = AuthenticationRememberForm(data=request.POST) if form.is_valid(): if not form.cleaned_data.get('remember_me'): request.session.set_expiry(0) login(request, form.get_user()) if request.session.test_cookie_worked(): request.session.delete_test_cookie() return HttpResponseRedirect(redirect_to) else: form = AuthenticationRememberForm(request) request.session.set_test_cookie() return render(request,'registration/login.html',{'form':form}) Views.py logout view def logoutv(request): logout(request) return HttpResponseRedirect('/') Setting have a SESSION_EXPIRE_AT_BROWSER_CLOSE = True in it already. Except this i made no changes anywhere related to sessions. -
prismjs for django template
I tried using prismjs in my django template , but i couldn't. Here i am uploading my files so that you guys can have a look. My code goes here... views.py def prism(request): return render(request , "latest_files.html") home.html {% extends "base.html" %} {% block body %} <pre><code class="language-Django"> {% for post in posts|dictsortreversed:"id"|slice:"18" %} <ul> <li class="pointer" onclick="location.href='{% url 'detail' post.id %}'">{{ post.title }}</li> </ul> {% endfor %} </code></pre> {% endblock %} I linked .js and .css files carefully cause it worked for python earlier. Thanks in Advance !
