django-webpack-loader not rendering react app using react-app-rewired
I'm working on tying my react and Django apps together. Right now I'm just working to get the dev server working and will focus on production later. I've been following a handful of guides on this process, but they're all a little different and I haven't been able to find the right combination to get this working. I'm using react-app-rewired because I'd like to not have to eject. My understanding is that its more desirable to not eject and manually configure all of the Webpack configs. This may especially be true as I'm still learning react/webpack. Its my understanding that once this is configured I just need to run the Django server and it should display my app. I'm not running collectstatic or any npm start or build commands. Here's what I have configured: base.py ... STATICFILES_DIRS = [ # os.path.join(os.path.join(BASE_DIR, 'frontend'), 'build', 'static') os.path.join(BASE_DIR, "frontend", "build", "static"), ] ... local.py ... WEBPACK_LOADER = { "DEFAULT": { "CACHE": not DEBUG, "BUNDLE_DIR_NAME": "frontend/build/static/", # must end with slash "STATS_FILE": os.path.join(BASE_DIR, "frontend", "build", "webpack-stats.json"), } } ... config-overrides.js var BundleTracker = require('webpack-bundle-tracker'); module.exports = { webpack: (config, env) => { config.plugins.push( new BundleTracker({ path: __dirname, filename: './build/webpack-stats.json' }), ); return config; }, … -
How to display the website three inside page? Even an instance

How to use django with a sqlcipher encrypted sqlite database
I am trying to integrate my sqlite database, encrypted with sqlcipher, to my database and have found very little support for this online. I have set my engine to 'django.db.backends.sqlcipher.backend' or 'sqlcipher.backend' and keep getting this type of error django.core.exceptions.ImproperlyConfigured: 'sqlcipher.backend' isn't an available database backend. Does django need a specific backend for each database type that is tailored for django-db integration? I only found this that I couldn't get to work https://github.com/codasus/django-sqlcipher and an SO question that never got answered Set database engine to sqlcipher in Django Any one have any ideas on preferably how to make this work, or otherwise know of an easy way to encrypt an sqlite database and integrate with django? -
How to load the data within the viewset class automatically on the server?
I had the backend Django project running on EC2, Ubuntu18.04, nginx. Basically, when I test the project locally by running 'python manage.py runserver', i can see the matrix i want to generate loaded before the server is ready to go. However, after i deployed it on the server, it gave back the error that the views doesn't have the attribute called 'matrix'. I tried locally, and i can see my prints so that it truly generate the matrix. However, i cannot debug the project as the same way i did locally as i run the project automatically by setting up the .conf file. module 'test.views' has no attribute 'matrix' class CreateMatrixViewSet(viewsets.ModelViewSet): serializer_class = MatrixSerializer queryset = Matrix.objects.all() print("start creating ls_frame") global ls_frame ls_frame = read_frame(queryset) print("end creating ls_frame") print("start creating matrix") global matrix matrix = generateMatrix(ls_frame) print("end creating matrix") http_method_names = ['post'] def create(self, request): ... I assume that when running on the server, it won't do the initial loading. So if i want to generate something before i make the server ready, what should i do? -
Get around Internal Server Error for Hello World django project in production
I have my apache server directing traffic from mysite.com/home to my wsgi.py file, but when get_wsgi_application() is called I get an internal server error. Running apache2 on amazon linux EC2. In wsgi.py, I've replaced the line, application = get_wsgi_application() with the function, def application(environ, start_response): status = '200 OK' output = b'sys.path = %s\n' % repr(sys.path).encode('UTF-8') output += b'sys.version = %s\n' % repr(sys.version).encode('UTF-8') output += b'sys.prefix = %s\n' % repr(sys.prefix).encode('UTF-8') response_headers = [('Content-type', 'text/plain'), ('Content-Length', str(len(output)))] start_response(status, response_headers) return [output] and the server error goes away. It shows that apache is using the correct python version (3.7) and doesn't return an error when I import get_wsgi_application() from django.core.wsgi. To my understanding this means apache is finding the access point to my django project just fine, and it has permission to look into the file and show its contents. What am I missing? Other possibly relevant information I can think of: user "apache" and group "apache" own the outer mysite directory and everything in it. I've set all the settings in settings.py for production according to the django deployment checklist. https://docs.djangoproject.com/en/2.1/howto/deployment/checklist/ wsgi.py: import os, sys from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings') sys.path.append('/usr/local/wsgi/django') sys.path.append('/usr/local/wsgi/django/mysite') application = get_wsgi_application() httpd.conf: <VirtualHost *:80> ServerName www.mysite.com … -
Overloading changelist_view with no changes causing errors
Overloading changelist_view and calling the super() causes attribute errors. I'm creating a super basic dashboard and I am overriding the changelist_view method of a ModelAdmin class. However, this override is resulting in an error "NoneType object has no attribute 'has_header'." However, I'm literally not doing anything but override the changelist_view and calling the super class - I haven't made any changes yet. In admin.py class SummaryAdmin(admin.ModelAdmin): def changelist_view(self, request, extra_context=None): response = super().changelist_view(request, extra_context) The corresponding model in models.py class Summary(Failure): class Meta: proxy = True verbose_name = 'Failure Summary' verbose_name_plural = 'Failures Summary' This is literally the entire contents of the admin model. When I try to go to the django admin panel, I get the attribute error. As far as I can tell, this should be no different than not overrifing changelist_view at all, but if I delete the override everything functions as normal. -
How do I stay on the same page after submitting a post request and hit another post request?
I'm doing a one page website where I'm wanting to input some text and upload files. Basically, how I want my form to look like at the front end is, first I can type some text in the textarea given, below that I should be able to select multiple files, once the files are selected I'll click on the upload button, the files should be uploaded, and then I'll hit submit and that's how I create a post. I'm attaching my code below. I do have written my broken views.py file but I'm not attaching it for now. models.py : class Post(models.Model): post_body = models.TextField(blank=False, max_length=500) class PostMedia(models.Model): file = models.FileField() body = models.ForeignKey(Post, on_delete=models.CASCADE) forms.py : from django.forms import ClearableFileInput from django.forms import ModelForm from .models import Post, PostMedia class PostModelForm(ModelForm): class Meta: model = Post fields = ['post_body'] class PostMediaModelForm(ModelForm): class Meta: model = PostMedia fields = ['file'] widgets = { 'file': ClearableFileInput(attrs={'multiple': True}), form.html (I was trying to write the jquery function): <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <script> $('text-form').on('submit',upload(e) { e.preventDefault(); $.post( '../create-post', $('form').serialize(), function( data ) { alert( data ); } ); }); </script> <div class="site-form"> <h2>Create a New Post here! … -
Django global filter
Is there a way to filter globally a Django model? We need to set a filter in a single place so that it gets applied in all queries generated by Django ORM including related objects lookups etc. Example: class A(Model): n = IntegerField() class B(Model): a = ForeignKey(A) We want to set on A a global filter id__gte=10 (static to make it simple). The filter must be then automatically applied also when doing related queries, e.g. B.objects.filter(a__n=123) # this code cannot be modified should expand somehow magically to an equivalent of B.objects.filter(a__n=123, a__id__gte=10) We can change models, managers, querysets but we cannot change the code where objects are actually queried (a lot of code, third party apps, generic API). -
Converting raw sql query to Django ORM
I have 3 models in my projec like this: class Model_A(Models.Model): field_a_1 = models.IntegerField() ...other fields... class Model_C(models.Model): field_c_1 = models.IntegerField() field_c_2 = models.IntegerField() ...other fields... class Model_B(Model_C): table_a_fk_id = ChainedForeignKey(Model_A, .... ) ...other fields...

NOAUTH Authentication required. Redis settings on docker compose for django
I keep on getting the error message: redis.exceptions.ResponseError: NOAUTH Authentication required.. (I'm using celery to perform background tasks). My settings.py looks like this: CELERY_BROKER_URL = 'redis://user:my_strong_password@'+REDIS_IP+':6379/0' the docker-compose I have: services: redis: image: redis:latest container_name: jh_redis ports: - '6379:6379' command: redis-server --appendonly yes --requirepass my_strong_password you can see that my attempt to provide the password (--requirepass) is exactly as it shown in the settings.py however, while the docker is up and running I still get the subject error message. I have tried different combination such as: --requirepass user:my_strong_password but still didn't work. Note: when I take off the entire command line - it works (but 32 hours after - I get the error message and it stop working). What should be the appropriate settings in docker-compose to have it work smoothly? -
How to add disable password for django users
I have created a tool for my colleagues and i have integrated SSO with this django application as well. Now the way i'm planning to authenticate users are like the following. SSO page is sending the logged in user ID in cookie. If the logged in user have an account in django users, i'll check for a match and i should authenticate the user. The challenge i'm facing here is while creating users i have to provide password and i don't want to validate user password again. Is there a way i can disable the password while we add the user in to django admin itself? I'm using Django 1.11 with python 3.4. Let me know your thoughts. -

Django Select2MultipleWidget not allowing multiple selection

How to render the options in a select of a Django form?
I would like to render two selects with Django (one multiple select, the other a simple one) and customize it with Materialize. I manage to code the following: In my forms.py class ZonesForm(forms.Form): zones_options = ( (1, 'Zone 1'), (2, 'Zone 2'), (3, 'Zone 3'), (4, 'Zone 4') ) zones = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple, choices=zones_options) conn_options = ( (1, 'ABCDE'), (2, 'FGHIJ'), ) connections = forms.ChoiceField(choices=conn_options) In my zones.html {% block content %} <div class="container"> <div class="row"> <form method="post"> <div class="input-field col s6"> <select multiple name="{{ form.zones.name }}"> {% for opt in form.zones %} <option value="{{ opt.id }}">{{ opt.label }}</option> {% endfor %} </select> <label>Zones</label> </div> <div class="input-field col s6"> <select name="form.connections.name"> {% for opt in form.connections %} <option value="{{ opt.id }}">{{ opt }}</option> {% endfor %} </select> <label>Connection</label> </div> </form> </div> </div> {% endblock %} My problem is: when the page is rendered, I get 4 checkboxes for the first select (as expected), and no names for it (all options are blank). For the second select I get 4 options (one blank, one with 'ABCDE', one blank, one with 'FGHIJ'). I suspect that the problem is with the attributes.

Django Gmail API send EMails
Im already using Gmail API for login in my Django project. Im using social-auth-app-django 2.1.0 SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = 'XXXXXX.apps.googleusercontent.com' SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = 'XXXXXXX' now I want to extend this and also send emails via the Gmail API. This means that the sender of the email is the user's own email and not the one from the project page. I've been looking at the reference here. https://developers.google.com/api-client-library/python/guide/django But it doesn't seem to be up-to-date, already the modules CredentialsField and FlowField can't be imported. So my question is, is it possible to integrate this directly via social-auth-app-django as described? If so, how could this be implemented? Unfortunately I didn't find anything suitable on the internet how I could realize it in Django. Im using Django 2.1.3 on Python 2.5.4 -
How to merge the result of two queries using update
I have to show the name of the category and the quantity of items in each category. The items can change the category, so I save the history of the items in the table items_history To show all the category name I'm running this query: category_total = Category.objects.all() Example of result: <QuerySet [<Category: Drink>, <Category: Food>, <Category: Fun>, <Category: Suplies>]> To get the quantity of items in each category, I have to check in the table items_history: items_history = Category.objects.filter(items_history__current=1).annotate(qtd=Count("items_history__idea_id")) Example of result: <QuerySet [<Category: Food>]> items_history[0].name -> 'Food' items_history[0].qtd -> 5 In this case, I have only items in Food Category. So I can't do just one query in items_history, because I'm not gonna get the quantity of the items in the other categories (0, in this case). I need to get all the categories with their respective quantity, so if a category is not persisted in items_history I should get the category name and the quantity = 0. The result expected: items_history[0].name -> 'Drink' items_history[0].qtd -> 0 items_history[1].name -> 'Food' items_history[1].qtd -> 5 items_history[1].name -> 'Fun' items_history[1].qtd -> 0 items_history[1].name -> 'Suplies' items_history[1].qtd -> 0 I'm trying to use update to merge the result of category_total and items_history … -
registered router url returns 404
I'm using django and rest-framework to develop a website. I have a users app in which the models are shown below: class User(AbstractUser): pass class Comment(models.Model): comment_text = models.TextField() author = models.ForeignKey(settings.AUTH_USER_MODEL,default=DefaultUser,on_delete=models.SET_DEFAULT,related_name='author') # DefaultUser is similar to AnonymousUser in django.contrib.aut.models date = models.DateTimeField(default=now) class User_Comment(Comment): on_user = models.ForeignKey(User,on_delete=models.CASCADE,related_name='on_user',default=DefaultUser) class User_Comment(Comment): on_user = models.ForeignKey(User,on_delete=models.CASCADE,related_name='on_user',default=DefaultUser) so it's basically a comment system where a user can comment on another user. I've used a rest framework serializer for posting comments: class User_CommentSerilizer(serializers.ModelSerializer): comment = User_Comment class Meta: model = User_Comment fields = ('comment_text','on_user') # extra_kwargs = {'password': {'write-only': True}} def create(self, validated_data): comment = User_Comment( author= User.objects.filter(username=self.context['request'].user)[0], on_user= User.objects.filter(username=validated_data["on_user"])[0], validated=False, comment_text= validated_data["comment_text"] ) comment.save() return comment and then using a UserCommentViewSet in views.py: class User_CommentViewSet(viewsets.ViewSet): serializer_class = User_CommentSerilizer queryset = User_Comment.objects.all() and finally in the urls file I've registered the view: router = DefaultRouter() router.register('profile' , views.UserViewSet) router.register('comment' , views.User_CommentViewSet) router.register('login' ,views.LoginViewSet, base_name='login') urlpatterns = [ # path('', views.GetUser.as_view()), path('users/', include(router.urls)), ] the profile and login routers are working fine. however the comment router is not showing at all (and returns 404) without raising any other error.

For some reason the context dictionary does not include the 'form'.
