I have made some changes to a Django template, saved them, committed them to git, pushed to GitHub and then deployed this new version to Heroku.
The build succeeds and I can view the template but the change is not there.
I checked the GitHub repo, the change is there. When I check the activity feed on Heroku I can see the change when I click the Compare diff link.
When I make changes to other areas of the project, views etc there's no problem, I have updated other templates without issue but can not get the new CSS into the deployed version.
Inspecting the code of the deployed version shows the old CSS not the new so it isn't just an issue with my stylesheet, inheritance or so on.
I've run out of ideas, any suggestions of how I can resolve this?
I have found an answer, it seems a little like using a sledge hammer to crack a nut but ...
Anyway I deleted the templates directory, went through a cycle of commit, push deploy. Reinstated the templates directory redid the commit, push, deploy cycle and for whatever reason the CSS is now being picked up and displayed as expected.
I still have no idea what the original problem was, why it happened or how probable it is I will have the same sort of issues again so any suggestions, explanations and clarifications would still be much appreciated.

I've got a Django site which uses the "django-machina" forum software, which in its latest incarnation apparently uses Bootstrap4 styling.
After installing the package according to directions, it looks beautiful on my development box. But, when I deploy exactly the same software on production, Bootstrap obviously isn't running because nothing is properly styled.
There are no 404's and no console messages. *(Yes, I remembered to run manage.py collectstatic ...) There are some stylesheets complaints from Firefox but they're identical in both cases. But ... the display is not!
Can anyone suggest what I might do in order to solve this problem? I'm stumped!
Well, once again I answered my own question!
I correctly guessed that, since I was maintaining the remote site from my own box using rsync, there might be some garbage left over on the remote side that wasn't being swept-up. (I can't use rsync --delete for fear of smashing directories that contain images and uploaded materials.) I guess it would probably be smarter for me to start using an external repo so that git can do for me what it's designed to do ...
But anyway, when I deleted selected directories containing the central and most-often updated directories, then used rsync to replace them with clean copies, the interference went away and production now looks correct.
I'm new to git. I've read the well-written intro book. But gee, it's still not a trivial topic. I've been bumbling around, experiencing various problems. I realized it might be because I'm unaware of workflow, and specifically, "what are the best practices for doing what I'm trying to do?"
I started out developing a django project on my win7 with Pycharm. Great way to get the initial 95% written.
But then I need to deploy it to my production machine at PythonAnywhere.
So I created a private Github repository, pushed my win7 codebase to github.
Then in pythonAnywhere, I cloned the github repository.
For now, no others work on this project. It will not be released to the public.
Now that the server is running on PythonAnywhere, I still need to tweak settings, which is best done on the PythonAnywhere codebase side. But there are other improvements (new pages, or views) that I'd rather do inside Pycharm IDE on my win7 than in vim on python anywhere.
So I've been kind of clumsily pushing and fetching these changes. It's been kind of ham-handed, and I've managed to lose some minor changes through ignorance.
So I'm wondering if anyone can point to a relatively simple workflow that would handle the various tasks I mentioned:
1) improving functionality of the site (best done in Pycharm IDE)
2) production server issues and tweaks (best done on PythonAnywhere)
3) keeping everythign safely backed-up on Github
The other issue is that I have another django app that I want to build. It's easiest to temporarily hang it off the django project I've already built. But I'd prefer to keep it in its own repository.
So I have Original_Project, Original_App stored in Original_Repository
I want to make new_app, and have it, for the time being, run in Original_Project, but I want to version control it in New_Repository.
I think/hope that I could put a .gitignore in the Original_Repository, saying ignore the new_app/ Then I git init new_app/ as its own repository. Is that sound or mad?
You should avoid editing your code on the production server as much as possible, and never commit from the production server. If you end up having to tweaks things on the server (you shouldn't but well, shit happens and sometimes it's indeed easier to first get the code back to work on the server), then once it's working manually report your edits to your local repo, clear up the changes on the server and deploy the fixed code again. Here the github repo should be considered as the "master" repository for deployments, ie you work on your local repo, push to github, and on the server pull from github. This make sure you keep the github repo in sync.
wrt/ the "improving functionality" (aka "features") vs "server issues and tweaks" (aka "hotfixes"), git flow is a (mostly) sane workflow IMHO but that's a bit opinion-based here (some dislike it and have sensible arguments too).
Finally if you want to factor out one of your apps, the best is to have it in it's own (github) repo with all the proper python packaging stuff and make it a requirement of your main project. On your local dev environment you install it as an editable package, and for the production setup you install it as normal package pinned to the last stable version. Note that in both cases I assume you're using virtualenvs (and if you dont, well that's the very first issue you should address).
Update:
What are the downsides of of editing directly on the production server and committing from the production server?
Well quite simply a production server is not the place for coding - "production" means that you have users trying to do something with your website and they don't want to have the site breaking on them, their data lost or whatever because you are "tweaking" things. You should only deploy stable, well tested code on production, and the one and only one case where editing anything on the server might be a last resort option is when it's already broken and you want to get it back online asap whatever it takes (case of "first make it work, then make it clean").
Point is, I'm a professional developer working on projects that are business criticals and a broken site is not an option, so I'm very strict on this - but even if it's a hobby project, your users deserve some respect (at least if you expect to see them back).
A proper production chain actually involves at least three environments: your local dev environment, a staging server (which should closely mirror the production server - system, system package versions, configurations etc etc) to test out / showcase / eventually do minor config tweak, and the production server which should only ever see stable tested code.
I have always struggled with git, knowing it well enough to get thigs working, but never being sure I am doing thing well.
I would suggest installing git flow (it is probably available in your package manager if you are on Linux). Its a set of extensions that simplify a standard git worklfow. Since using it, this has pretty much been all the documentation I have needed.

I built a (relatively simple) Django project following a tutorial (the recently released Hello Web App book.) I committed my changes along each step of the way, and I have my working solution in a github repo. However, when I clone the code into a new work space such as onto a new machine or into a new slot on a cloud IDE, the app doesn't work. I get a few errors and with each I resolve, another pops up. Basically, my environment is totally messed up and incompatible with the app beyond having Python and Django both installed.
I realize that I can read through the error messages I get when I invoke runserver, solve each one by one, etc. but it seems there should be a cleaner/simpler way to be able to pull down my repo to a fresh workspace and have it up and running in just a minute or two. I've read recommendations about using virtualenv, but it also seems like people discourage including venv inside your repo because of the extraneous commits and added bulk that will result from it so I don't think that actually solves my problem of trying to reduce new workspace configuration effort.
Perhaps I am overly optimistic, but I'm hoping someone can give me a recommendation to avoid the need to workout these kinks each time I start fresh.
I currently use the lovely Github Pages to host a website. I would now like to try out some stuff, adding content, new scripts, ... So I have a dev branch in which I do this, and run a local webserver to test it. Once I'm happy with it I can push it to the gh-pages branch for 'release'.
However, I was now wondering. Is it possible to have the dev branch also be reachable anywhere just like the gh-pages branch? This would be very helpful in letting other people try out the new stuff I'm working on without having to risk releasing buggy code to everyone. So basically two gh-pages sites in one repo, one for release one for development.
Is this (or something similar) possible with Github?
So going carefully through the github pages documentation seeking for any solution using the offered functionalty it seems what you are looking for might have been nice but is not available, maybe the closest thing is to have two repositories for example username.github.io/production and another one that is forking it like username.github.io/development and working on it while pushing changes back to the production one using pull requests or any technique you would prefer
And if you like you can check out my post and see some techniques of altering your websites, as well jekyll has a _drafts directory which allows staging of a post and seeing it before being posted.
I think any branch can be reached via rawgit.com.
For example, if your user/organization is XYZ, you can reach the dev branch for your user/organization jekyll site at:
http://rawgit.com/XYZ/XYZ.github.io/dev/_site/index.html
Just don't include _site in .gitignore. You still have to build the site locally with jekyll build, so it's still not a perfect solution.
Title is pretty much my question. I'm serving the dist directory differently and would still like the benefit of auto-builds but I don't need to run the server. I looked in the docs and the cli help but didn't see anything specific. I know the cli help doesn't contain everything because it doesn't list ember build which is available.
If I understand correctly you are wanting the ember build command to watch for changes in the file tree and rebuild on a change?
They implemented ember build --watch a while back which will trigger when a file changes. Tested just now and it worked on 0.2.7. Not sure what version it came in though. Let me know if this is not the answer you are looking for.
