'app.config.assets.configure' is 'undefined' in 'handlebars_assets/engine.rb'

[happyvig]

What value should be configured in the (gem consuming) Rails (2.3) app's application.rb so that 'app.config.assets.configure' comes defined in engine.rb ?

Rails 2.3 reached EOL on 2013-06-25; I would recommend updating your Rails application.

There might be an old version of handlebars_assets that would support that old version of Rails, but it is pretty unlikely since a lot changed between Rails 2.x and 3.x. I would personally not recommend going this path.

Apologies. My mistake. My Rails version is 3.2.22.5

Any specific 'Sprockets' gem version to be used ?

I am using "sprockets" --> "2.2.3" & "turbo-sprockets-rails3" --> "0.3.14"

One quick note :
I dont use '/app/assets/javascripts' folder. Instead I put all my javascripts & hbs templates folder inside '/public' folder. I haven't tried deploying this code to my server yet. Do you foresee any errors in this folder structure approach ?

I created an initializer called handlerbars_init.rb to update the 'path_prefix' config value :

HandlebarsAssets.configure do |config|
config.template_namespace = 'HandlebarsTemplates'
config.path_prefix = '/public/javascripts/templates'
end

@happyvig I would not recommend doing this in public; there is a reason public is different then app/assets/javascripts ; generally using rails and going against convention will be bad news.

the public folder is used for static assets POST compilation; by putting your assets in the folder you may have conflict; and access to public files will be available in most environments (exposed to public).

[happyvig]

True. Valid point there.

Question 1 :
Any specific 'Sprockets' gem version to be used when using 'handlebars_assets' v0.23.2 gem ?
I am using "sprockets" --> "2.2.3" & "turbo-sprockets-rails3" --> "0.3.14"

Question 2 :
And also template namespace override is not working when specified via an initializer as

HandlebarsAssets.configure do |config|
    config.template_namespace = 'HandlebarsTemplates'
    config.path_prefix = '/public/javascripts/templates'
end

or by specifying inside config/application.rb as
HandlebarsAssets::Config.template_namespace = "HBS"

Appreciate your thoughts about this.

Q1. not that I am aware of; last time I was running with sprockets 3 I believe (its been a long time)

Q2. not sure how that could be happen, and I don't really have time to debug; most of the code is at: https://github.com/leshill/handlebars_assets/blob/master/lib/handlebars_assets/handlebars_template.rb and I believe everywhere is correct for use of template namespace.

Thank you.
I have figured out that the latest version of the gem (0.23.2) is not working with Sprockets 2.x and that's why it was throwing ''app.config.assets.configure" as undefined for me.

I believe "app.config.assets.configure" gets defined in the Sprockets 3.x (not tested)

Since my app uses Sprockets 2.x currently, I am planning to use a lower version of the gem (0.20.2) which does not rely on 'app.config.assets.configure' method.
