Added Rails version to create_shops generator template

[AWaselnuk]

Closes #415

Rails 5 requires the Rails version in the migration parent class apparently. This PR adds that via an erb template. It has to be in a minor version format [x.x]

Do I need to bump a version number somewhere?

I'm having this exact issue. Now I'm trying to add gem 'shopify_app', '~> 7.2.10' to my Gemfile (with the new version), but I get the error:

Could not find gem 'shopify_app (~> 7.2.10)' in any of the gem sources listed in your Gemfile.

We haven't cut a release yet. You can point your gemfile to github for the time being.

I'm using this:

gem 'shopify_app', '7.2.10', :git => 'https://github.com/Shopify/shopify_app'

And it looks like it installed correctly. But I'm still getting the original error:

Directly inheriting from ActiveRecord::Migration is not supported.

[kevinhughes27]

Try master aka remove the version

I tried it with a fresh rails app and it worked.

[kevinhughes27]

Are you using github master in your gemfile? This worked for me last Friday with rails 5.1. We'll try and cut a release today.

[amorimlucas]

Yes, using the github master got it to work for me.

Another question: Do you guys know how to load your embedded app using localhost:3000 for your URLs? I tried using a self-signed SSL, but it didn't work.

[kevinhughes27]

I use ngrok or forwardhq which has ssl

[jamiemtdwyer]

I'm a massive fan of ngrok

I know others have successfully gotten self-signed SSL certs to work but I find it's not worth the hassle.

[amorimlucas]

Got it to work with ngrok, thanks!
