I'm looking to move the app to a shared hosting service like webfaction or dreamhost to demo to my bosses and argue my time should be spent on this versus things that actually generate revenue for the company. Hi, I'm the Bokeh project lead. The bokeh-server is definitely intended for people to be able to run, either on their own local on-premise assets, or in some hosted/cloud situation. There's several ways to run it: It has a Flask Blueprint, so if you are using Flask you can incorporate it directly into an existing Flask server. Otherwise, it can be run as a command-line tool (config options supplied on the command line as well) or, you can import the server and run it from python code. I don't know about the particulars of your deployment, but you would probably just want to start it using whatever startup script controls your deployment, then your django app can interact with it either by templating documents that load plots, etc. from the bokeh-server, or but storing plots and data on the server using the plotting APIs.

Are there any tools people can recommend for importing data when you don't have control of the source? I have a bunch of excel documents (and models I've written for them)- I can read the data from the documents just fine but it seems like writing the import code will be a huge unmaintainable mess since I'm basically duplicating my models code but in a different place.

I made a couple custom management commands for importing data into my app. No need to duplicate your models in that case, since you can access everything in your project from the management command.

As a first project, I'm turning a small personal script into something with a web interface using Django, and I can't for the life of me get configparser to work, even with just running locally.  I get a NameError (which basically means configparser is trying and failing to assign value from the .ini file) every time. Doesn't matter if I make it just creds.ini or /backend/creds.ini or /screlp/backend/creds.ini. I've got the four values hardcoded for now, but it's obviously not wise to git those. Also hello there little docstring incongruity, I see you!

You should generally define a DJANGO_ROOT variable in your settings that's the root path of the whole project. Your config.read() should call os.path.join(DJANGO_ROOT, etc., etc., etc., etc.) to point to the creds file. Alternatively (and probably as a better practice), credentials should be defined as environment variables and read in using os.environ. Generally keys, credentials, and sensitive information like passwords should be defined as environment variables so as to keep them out of source.

With the OP being 6 years old at this point, is there a recommend book for learning the basics of Django? A Django for non-programmers book? I've been teaching myself Python to help out at work and I've interested in learning and creating a web app.

Django updates semi-frequently. Have you done the official tutorial? If not, maybe try that and ask questions about it here. The book that has been talked about the most in this thread recently is Two Scoops of Django, but that's less for teaching beginners, and more for laying out best practices for people already using Django. Now, that's not to say you shouldn't read it. You should definitely read it.

Using database-backed sessions, is PickleSerializer always a bad idea? The docs say to not use it with cookie-based session data but I've seen calls elsewhere to just not ever use it at all. I'm updating an old app originally written in 1.3 which stores a lot of datatypes the JSONSerializer doesn't seem to like (decimals, dates). I probably should rewrite the whole thing anyway but I was hoping to avoid that right now.

Does anyone serve angularjs (or any other kind of 1-page html/js) apps through django or have good ideas how to do it? I'm trying to think of a neat way to achieve it and keep running into knotty problems. It seems like you want to have a django app for your angularjs app, that has AppView/API URLs, and a templates folder with an index.html that somehow includes your angularjs app .html, but getting this to work with my versioned, cache-buster js/css produced by grunt tasks etc seems like a challenge.

I put my angular stuff in staticfiles, and then end up serving them off of a CDN. The only angular in a django template is the reference to the script and a root node tagged with ng-app (and usually a directive that loads a template). I usually also make an API app that the angular client talks to.

Yeah, that's all logical stuff  thanks. I think i really need to move away from serving apps via django to be honest. Its just not very robust.As an aside: How do people here like to setup their dev environment at home? I'm disliking my current situation which is a dual boot of Ubuntu on my windows machine, its a hassle to power down/boot up a different os if I want to do something else. I've heard people talk of using virtual machines, which sounds fine but is there any way to run them so that they "feel" native while you're using them? As in span across multiple monitors seamlessly and just have a key combo or something to switch back to windows. Failing that I guess I buy a dev laptop and just plug it in when needed, portable solution but expensive

How about using Vagrant? You develop as normal on your windows box, but the code runs in the vm.

Id want to do my development in a Linux environment, I just couldn't get used to using windows to develop again.

But then I'm running vagrant in a Linux vm and things get complicated possibly.

I'm having trouble deciphering AWS's pricing structure though- it seems to be a case of "Don't worry we'll just take the money if you do anything expensive" but I'd like to know roughly how much I'd be spending or whether I could just mooch around in the free-tier. I guess I'd be averaging no more than 80 hours of dev time a month + some cloud storage of VM images/backups etc.

I use both Django's runserver during development but then I use a Vagrant VM (provisioned with Chef) for testing before I push it to production. Try the free tier first, if you outgrow it, it's really inexpensive to run an EC2 VM for only 80 hours a month. The storage and all that is super cheap, just calculate your monthly cost on the instance price per hour * number of hours per month.

Right on, thanks Dominoes! I'm starting a new project using Django Rest Framework (which I've used previously) and React (which I have read about but not used yet). Any tips I should keep in mind? I think Thermopyle was doing some DRF/React stuff. Should I just have 1 Django view (index) and make it a single page app?

fletcher posted:Right on, thanks Dominoes! I think DRF is the best at what it does, but it's still a lot of work when you go beyond the very basics. POSTing nested models just isn't worth the effort. In many ways, you're better off doing a POST to create the related model, and then a POST to create the parent model. If that's not clear I'm talking about like if you have two models, ModelOne and ModelTwo. ModelOne has a FK field to ModelTwo. It's convenient to have an API endpoint for ModelOne return the data for ModelTwo nested inside, like: code:The POST to create a ModelOne instance after I've created ModelTwo would look like this: code:As far as your views...you can do it any way you want. I've been transitioning a complex project over to React, and I've got multiple views. If you want to do a SPA, it's easy enough, just be aware that you'll be writing a lot of JS!

Good news on the DRF3 front though... https://www.kickstarter.com/projects/tomchristie/django-rest-framework-3 quote:The most pressing need for Django REST framework is a major overhaul of the serializers. This is currently the most awkward and complicated part of the project and it is in need of serious improvement. The aims of redesigning the serializers API would be:

Even though your API consumer has to do more round trips, the clean separation of concerns on the backend is actually pretty nice. It makes the views and serializers simpler. If DRF3 can keep that simplicity while better handling nesting, I'll be ecstatic.

What's everyone using for rich text input these days? I was using django-markupfield but it's not being updated for 1.7 due to architecture issues or something. Given that I'm only making a simple personal website and I've got no content up there already I'm not attached to it enough to consider rolling back to older versions of Django. Plus it'd be nice to use a fancier input widget that would show a preview mode since I tend to gently caress up the markdown syntax often. I'm looking at django-epiced since it appears to prerender the markdown text and saves the html alongside the original in the database which is something most other fields/widgets don't seem to do (not that load is going to be at all a concern, I just don't think rendering the markdown every page load is ideal considering the source text is rarely going to change), plus it actually defines a field so I don't need to do anything special to use it. I'd love other suggestions though.

I figured 'api(/?)' and 'api/?' should both match 'api' and 'api/'? When you capture a group in an url regex it gets passed to the view which is the second parameter of the url function. It looks like either django or DRF is choking on this unexpected group getting passed to it. Whatever it is that is happening exactly it doesn't matter, because you don't need to do this at all. DRF will already handle urls with or without the trailing slash. Just put url(r'^api/', include(router.urls)), and you'll get your api root whether you visit blahblah.com/api or blahblah.com/api/ if you're using the SimpleRouter or the DefaultRouter .
