I Implemented a class based view in the views.py though when I tried to update an employee I realized that it's like I'm trying to create new one yet I have the PUT method defined.

In this case, How to set uwsgi.ini?
I will use uwsgi on AWS EC2 service. I structured my server's workflow like this. Internet - ElasticLoadBalancer-a - webserver-nginx - ElasticLoadBalancer-b - web-application-django_uwsgi_server - RDS So between webserver-nginx and web-application-django_uwsgi_server, There will be communication through http data. Also you should know that I run web-application-django_uwsgi_server on a docker container. Like, docker run --name django_uwsgi -p 8080:8000 djangoproject_and_uwsgi:1.0 And I set uwsgi ini file like this. uwsgi.ini in docker container: [uwsgi] chdir = /sampledir wsgi-file = /sampledir/sample/wsgi.py master = true processes = 10 # cron = -5 -1 -1 -1 -1 /path/to/some/script harakiri=20 max-requests=5000 vacuum = true enable-threads = true single-interpreter = true lazy-apps = true # From this line, I ask these below options. http = 0.0.0.0:8000 # the socket (use the full path to be safe # socket = /path/to/your/project/mysite.sock # chmod-socket = 664 I'm newbie in linux and network, but heard that socket settings will be better than just setting like http = 8000. Because of http overheads. But I had webserver-nginx on another EC2 instance. In other words, webserver-nginx and web-application-django_uwsgi_server are not on the same EC2 instance(machine). QUESTION: In this case, How can I set socket or port settings appropriately? -

Separate processes for Dockerfile for dev and prod?
I have a project with the following structure. ProjectName/ βββ Dockerfile βββ api/ β βββ Dockerfile β βββ manage.py βββ docker-compose.yml βββ frontend/ β βββ Dockerfile β βββ build/ β βββ src/ βββ manifests/ βββ development.yml βββ production.yml docker-compose.yml has a database image that's common between both environments, and the dev.yml and prod.yml have similar but slightly different images for production and dev. Example: The api dev uses django and just runs python manage.py runserver, but in prod it will run gunicorn api.wsgi. And the frontend runs npm start but in prod I want it to be based off a different image. Currently the dockerfile only works with one or the other, since the npm command is only found when I use FROM node and the nginx command only shows up when I use FROM kyma/docker-nginx. So how can I separate these out when in different environments? ./frontend/Dockerfile: FROM node WORKDIR /app/frontend COPY package.json /app/frontend RUN npm install EXPOSE 3000 CMD ["npm", "start"] # Only run this bit in production environment, and not anything above this line. #FROM kyma/docker-nginx #COPY build/ /var/www #CMD 'nginx' ./api/Dockerfile: FROM python:3.5 RUN apt-get update \ && apt-get install -y --no-install-recommends \ postgresql-client \ && β¦ -

Looking solutions for performing full text search with low memory cost
I wrote a web application using Django to display products information. My database (MySQL) contains ~200000 records ( fields: brand, name, and img). I want to add a search function to my app (the search is performed on brand and name fields), I tried haystack with Whoosh, but I found it cost a lot of memory. Can anyone suggest a way to do it? The application is expected running on a cheap AWS EC2 (small memory). -
GeoDjango - LayerMapping: An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block
I am using LayerMapping to add a shapefile into the database. Here is the code I am using. The shapefile is ~100MB so there are a bunch of polygons to add. mapping = {'name': 'OBJECTID', 'poly': 'POLYGON'} lm = LayerMapping(TestGeo, 'toronto geo/PROPERTY_BOUNDARIES_WGS84.shp', mapping) lm.save(verbose=True) After running the above code, I'd see about 10 seconds of success message, showing something like Saved: 'name': 12345. Then 10 seconds later, the console would keep showing the message: Failure to save: {'name': 12345, 'POLYGON': (....)} An error occurred in the current transaction. You can't execute queries until the end of the 'atomic' block. It still keeps running after displaying the error message (I'm guessing it moved onto the next polygon object). After it goes through each polygon, despite the fact that the first couple hundred or so polygons showed a success message, none of the polygons from the shapefile were saved. I came across a similar error but the content doesn't seem to be related. Any idea why this is happening? -
how to return string for model class which its own field has choices in Django

Templates mixed up. Acquiring view from another template. Django
I am new to coding in general. After taking a Python and Django developer bootcamp class in Udemy, I started building a simple website with a blog based on what I learned. Everything seems to be working fine except on one particular view on the blog - the Drafts view. I used class based views with one html template as base which extends to all my htmls. What's happening is the Drafts view which lists all draft posts is supposed to look a little different from the Published view which lists all of the published posts. But it seems that the Drafts view seems to be acquiring the view of the Published posts. For example - the Draft is supposed to list all the drafts with the "Created date" instead of the "Published date". The weird thing is that it's displaying the correct items - all the drafts but it's showing the published date instead of the created date. I also made like a sub navigation bar which is supposed to look different on the Drafts but it's displaying the one for the Published posts. Clearly, something is mixed up and I think this is a unique issue. Could you β¦ -
How to Preserve the Validity of Django Template Code in BeautifulSoup

The lxml parser's output is slightly different than above, but still invalid.

It's my first question, english is not my native language so please take it easy on me hahahaha Ok, so here is the problem, I believe it's a ident... idk how to say it in english but anyway, structural problem. What's happening: I'm learning following the tutorial and in my localhost website almost everything is running clean but when I decide to "vote" on a "Question", it leads to a error page. Here's the traceback (the final line): django.template.exceptions.TemplateSyntaxError: 'for' statements should have at least four words: for choice question_set.all and where the error (I believe) is placed, my "/results.html" file: <h1>{{ question.question_text }}</h1> <ul> {% for choice question_set.all %} <li>{{ choice.choice_text }} -- {{ choice.votes }} vote{{ choice.votes|pluralize }}</li> {% endfor %} </ul> <a href="{% url 'polls:detail' question.id %}">Vote again?</a> Thanks for everything! hope it's understandable. (:
