What is the correct solution for uploading images to s3 asynchronously using zappa? (aws serverless)
env django zappa boto3 (s3) The flow what i envisioned is as next User append images by website(input file html) and submit. zappa lambda receive the images and toss to s3 upload function asyncly. website waiting uploaded image and show image url. Two ways to upload images save image to local -> upload(saved_img) encode to byte -> stream as byte problem In the case of the Async function, the / tmp folder seems to point to a different physical location. Save is possible, but cannot be recalled. There is a limit to the number of characters in sns when streaming in bytes. Long files such as images cannot be put in arg. Is there any other good way to upload images to Async? -
how to create a main vue component to communicate with page related components with no npm (with django and django rest framework)
I have coded an IMDB clone website with django and vue via cdn. The vue ui is enhanced with vuetify and the json rest api created by django rest framework is get, put, post or delete by axios. There is no npm or webpack depency and configuration. The repo is installed as a usual django application. I have uploaded the repository with dummy data to github, the link is below. the requirements.txt file has all the django related versions. vue and vuetify versions are 2.x The reason of using vue is to enable inteactive ui. The ultimate aim is to create an alternative admin interface using vue like plain old jquery via cdn. For now, the project runs quite well. However, I have to write all vue component code to all pages. I copy & paste, then change some state related stuff (data) and add or remove some methods. Those components change according to model fields and relation with other models. The main skeleton is same. I have experienced zillions of trials and errors, but I couldn't achieve the way to interact many page related components communicate with one main component. All vue codes exist in templates folder and there … -

Pip shows web socket error and I cannot install any packages
I tried installing django but didn't work. Instead it gave me this error...

My network doesn't have a proxy or is not connected to a vpn. I can download any other stuff but I just cannot download stuff with pip. Thanks in advance! -
Django--complex context or complex template?
I'm rather new to the Django world and am converting an existing Java/Javascript app to Django. The existing app has many complex queries and conditionals. I can solve most of those in the template, but it is starting to get ridiculous. Generally, is it better to put the database hits in the view and have a more complex context to pass to the template or simplify the context and burden the template? Or does it matter? Some quick figures--the database has 44 tables 16 of which are M2M join tables. There are four report templates--the only one I've tackled hits seven different tables. So far, I've found testing things in the template is quicker and more reliable than testing in the view class. But I'm inclined to push more of the logic back to the view and pass a more complex context to the template. Just wondering which way more experienced Django hands go.... -

Okay here's the catch. When I create a django project with django-admin.py startproject myproject and starts server like python3 manage.py runserver, it all works fine.

How to create a elasticbeanstalk database with 'eb create'
I'm trying to create an ElasticBeanstalk environment using the 'eb create' command for the django-python application I'm developing. All the default necessary aws-infastructures are created. (e.g. cloudformation, loadbalancer, targetgroups, ec2-instance and so on). My application uses a postgresql database. I'm using the following DATABASE-definition in my productive-settings: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ['RDS_DB_NAME'], 'USER': os.environ['RDS_USERNAME'], 'PASSWORD': os.environ['RDS_PASSWORD'], 'HOST': os.environ['RDS_HOSTNAME'], 'PORT': os.environ['RDS_PORT'], }} Which uses the default environment-variables, provided by default if the elasticbeanstalk-enviroment creates a database. I tried to automate the creation of the database using the ebextensions as described here I tried the following steps to create the database automated when executing 'eb create': I added the following entries to my '01_container.config' in the '.ebextensions' directory, which by the way is definitely used (because I manipulate other values here and they are correctly changed in the elasticbeanstalk-container-configuration) option_settings: aws:rds:dbinstance: DBEngine: postgres DBEngineVersion: 9.6.16 DBUser: 'anyuser' DBPassword: 'anypassword' I also tried to set the same values using the 'Configuration files' and 'JSON document' described approaches here and none of these worked So what I need to do is to execute 'eb create', let it fail with the KeyError: 'RDS_DB_NAME'. Go to the elasticbeanstalk-environment, I just created and … -
How to get AWS static file urls from Javascript?
I'm trying to get the urls to a few static images from my AWS S3 bucket. I have a couple of javascript functions that change the image a user clicks on (clicking on a like button turns it green). I'm having trouble getting those images to work. The farthest I've gotten was getting a 403 error (Forbidden), and I'm not entirely sure why. Right now, I'm defining a few url variables in script tag and calling them in my JS function. Defining variables: <script> var is_bookmark_url = "{% static 'img/is-bookmark.svg' %}"; var bookmark_url = "{% static 'img/bookmark.svg' %}"; var like_button = "{% static 'img/like-button.svg' %}"; var liked_button = "{% static 'img/like-button-liked.svg' %}"; </script> Calling Variables in JS Function: function changeLike(id) { el = document.querySelector('#' + id) source = el.src if (source.substring(source.length - 26) == "/img/like-button-liked.svg" || source.substring(33, 59) == "/img/like-button-liked.svg") { el.src = like_button_url; } else { el.src = liked_button_url; } } (I know my function is the opposite of elegant, but I wasn't sure how else to get the image names from the urls -- but it works at least.) The point where I'm having trouble is I'm getting the error GET https://appname.s3.amazonaws.com/img/bookmark.svg? AWSAccessKeyId=XXXXXXXXXXXX&amp;Signature=XXXXXXXXXXXXX%3D&amp;Expires=1586147111 403 (Forbidden) So it's definitely … -

Custom Model Attributes not being passed to template
I have a custom user model and have my settings.AUTH pointing to my custom model, 'Profile'. I am trying to display a page that will pick one of my Profile objects and randomly display them. Then, my user will be able to choose like or dislike. But I'm stuck at simply getting them to display. As I'm just getting a page that shows 'BIO' without the user's bio, nor the users photo. The logic in views.py is getting me to the template, but the info I need isn't showing up.

How to get limited results per page in django using pagination?
I am following a udemy course where I am making a real estate website using Django. I have come so far and have been fighting with the errors but I am stuck with the pagination error that I am facing right now. I see everything is working fine in the video but when I follow it exactly it does not work. The issue is that when I set a limit on items per page, it does not seem to be working as I see all the results on the same page. Here is my views.py from django.shortcuts import render from django.core.paginator import Paginator from .models import Listing def index(request): listings = Listing.objects.all().order_by('-id') paginator = Paginator(listings, 3) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) context = { 'listings': listings } return render(request, 'listings/listings.html', context) It's my Urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name='listings'), path('<int:listings_id>', views.listing, name='listing'), path('search', views.search, name='search') As you can see, I have set maximum 3 listings per page but I am getting all of them on a single page which is not what I want. It would be great if anyone could help. Thanks for your time and efforts. -

Python Django - HTML for REST API JSON data in Async
