Re: Decoupling Postgres database credentials in django for deployment.

Hi, I am sorry, but this doesn't really make sense. What do you mean by decoupling the data? Deploying to the cloud, will mean that you will need to setup a new database for your project - there you will get a completly new database, that won't be connected to your development data in any way. Y

Hi, Environment variables are the best option for not embedding sensitive information in files which have chances to be stored in places such as external source repositories (GitHub et al.). If you are working with orchestrators such as Kubernetes, you can use the "secrets", which are specia

Re: How to make asynchronous ajax requests if the server side work takes plenty of time to finish?

I think a typical approach would be, using Django celery to process your heavy workload in the background, and then when finished, notify the user via email, text, or maybe have a periodic async ajax call check to see if there are completed tasks not yet looked at On Fri, Mar 30, 2018 at 12:53 AM,

Re: Decoupling Postgres database credentials in django for deployment.

Env vars are considered bad in contexts where everything runs in the same... environment. And I too have considered them as hacks or as options to avoid by all means. But times are changing, and nowadays there is a move towards containerized apps, even outside the cloud context. And we are no

Re: Decoupling Postgres database credentials in django for deployment.

I have a concern about using environment variables to hold secret information, and an opinion about it. IF DEBUG is enabled, and there is a 500 server internal error, and the default 500 template is used to render the response, THEN *all of your secret information is shown in the browser

Re: Decoupling Postgres database credentials in django for deployment.

You're perfectly right about the "500 Error + DEBUG" case. One solution is to set DEBUG to off by default, and turn it on by code in the setting module if detecting that the app is executing in a dev or Q&A environment. Depending on your context, this can be done with rules based on the host

Re: Decoupling Postgres database credentials in django for deployment.

I agree to set debug to false in your production configuration file. Never debug on production setup. If need enable debug on, use in staging environment or with different django configuration files. On Fri, 30 Mar 2018 23:52 PASCUAL Eric, wrote: > You're perfectly right about the "500 Error

That code would be for Channels 1. Channels 2 is an entirely different import set - make sure you are using tutorials or answers specifically for 2. Andrew On Thu, Mar 29, 2018 at 4:52 PM, Luke Waltman wrote: > Hello Everyone, > > I am still having an issue with Channels that was never really s

Re: [django-channels] Which process sends message to all channels in a group during group_send?

When you do a group send, the message doing the sending fans out the send to all the target channels (currently using individual commands, and soon with a Lua script inside Redis). We're not using redis pub-sub - we use lists instead. Andrew On Fri, Mar 30, 2018 at 2:26 AM, krdeepak wrote: > Hi

Thanks Andrew. I looked at the code and was able to figure out how it is being done (including the comment to use lua scripts in the future). The deep dive into codebase keeps getting deeper (channels, channels_redis, aioredis, asgiref, twisted, asyncio ...). I am building a chat based game using
