Help porting Loomio to Sandstorm

Hm, yes we're doing semi-weekly releases, so we're actually up to 0.17.0 now (you can note the current version # on production - as of this writing 0.17.8). However, the changes aren't so massively severe as to cripple it, especially given that you're likely not dealing with the angular frontend that much.

Looking at that 2.1.2 tag is making my head hurt as well; I'm not sure why it's there.

I'm working on upgrading my port to 0.17.0. Unfortunately, it refuses to load any static assets with the following errors:

This worked fine with 0.15.0 so I don't know what the cause is. Also, unfortunately I haven't done Rails in half a decade, so I have no idea where to begin looking. Was something changed WRT static assets between 0.15.0 and 0.17.0? I looked at the diff of 0.17.0 and my sandstorm branch, but nothing jumps out at me.

I'd appreciate any help, as I'm officially out of ideas. Check out my repository https://dev.thewordnerd.info/nolan/loomio-sandstorm. You'll need Vagrant and Vagrant-spk installed, but at that point you can spin up an instance inside a VM and see it in action.

git clone --recursive https://dev.thewordnerd.info/git/nolan/loomio-sandstorm

I think if you do:

cd loomio
git checkout 4b81bb6

you should be back to the working version, as that looks like my initial changes pre 0.17.0 merge.

Thanks.

Arrrrr... Our funky lineman build system stikes again. Sorry about this.

The secret is hidden in lib/tasks/deploy.task

You need to run lineman build and cp -R lineman/dist/* public/ so that the client files are able to be served by the rails app.

Aha, that more or less did it. Thanks.

Now I have another issue in that I was editing the haml files under app/views, not the Lineman UI. When building/running the app, I set a SANDSTORM=1 environment variable so I can tweak the UI. In Lineman, what is the most idiomatic way to check for this environment variable and export something I can query for in the haml templates during the build?

One example is the logo. If the Loomio install isn't official, you output the hostname instead. I expect this is usually OK, but in Sandstorm that appears as something like "eb4c7aa000d30f9f31a5477b2a9920d5.local.sandstorm.io" which is a bit ugly. :) I'd rather replace that with something like "Loomio" in cases where SANDSTORM=1 is set in the build environment where Lineman is run. I'd also like to disable the link to your pricing plans in the start group form for self-hosters, unless there's some reason you'd like that intact (maybe you can check for officialness there too?)

I'm sure I can find the answer, but I'd probably have to understand Lineman/Grunt/several other frameworks first, and I'd honestly just rather get this done so folks have a nice one-click Loomio install. :) Thanks a bunch.

Hi @nolandarilek,

Check out app/helpers/angular_helper.rb, there you'll see where we set up the app configuration which is passed into the angular interface as the AppConfig.

I reckon some sort of line there like
custom: { sandstorm: ENV['SANDSTORM'] }

which will allow you to use AppConfig.custom.sandstorm in the angular side of things.

Excellent, thanks, that's entirely not where I was looking. :) I was in lineman/config/application.coffee, setting:

  haml:
    options:
      context:
        isInSandstorm: process.env.SANDSTORM?

Then accessing this.isInSandstorm from the templates. Unfortunately something appears to be swallowing the SANDSTORM environment variable somewhere and I can't figure out what.

I'll give your solution a try.

OK, spoke too soon, I don't see app/helpers/angular_helper.rb in 0.17.0. Was that created after 0.17 was released?

Oh.. right, it's been recently added. If you update to the latest (18.0), it will be there, alternatively in 17.0 it'll be in app/controllers/base_controller.rb

Hey, sorry for the slowness on this, I'm poking at it in my free time, and no offense, but this project is a bit heavy on dependencies and technologies. :)

Trying to get 0.18 running in Loomio, I see lots of attempts to connect to http://localhost:9292. I assume this is some sort of real-time thing for the Angular interface? If so, how do I start it, and is it something that only the app needs to connect to? Or do I need to expose it externally somehow?

Also, I see the following in my logs:

Started GET "/default-cover-photo.png" for 127.0.0.1 at 2015-11-26 02:54:08 +0000

ActionController::RoutingError (No route matches [GET] "/default-cover-photo.png"):

Thoughts on how to fix that? I thought I was generating all my static assets correctly.

I also see that the API uses the PATCH method in places, in setting volumes in comments for instance. Any chance this might be changed? Looks like Sandstorm's HTTP server may block the PATCH method for non-external APIs. I'm asking them about this as well, so perhaps there's hope of changing this from Sandstorm's side.

Thanks.

I just joined this group to say THANK YOU @nolandarilek I for one think it is utterly wonderful that you are porting Loomio to Sandstorm! :)
