问题
I have, in my app/assets directory, the directories javascripts and stylesheets, as any normal Rails app.
I wanted, however, to have a plugins directory as well.
Example:
app/assets/plugins/myPlugin1/somefile.js
app/assets/plugins/myPlugin1/somefile.css
Thing is, if I use
<%= javascript_include_tag 'plugins/myPlugin1/somefile.js' %>
I would get a 404 error, as
/assets/javascripts/plugins/myPlugin1/somefile.js
does not exist. I noticed, then, that "plugins" dir was trying to be accessed inside javascripts. I assume this have something to do with "javascript_include_tag".
After some research, I realized I had to include this line into config/application.rb
config.assets.paths << Rails.root.join("app", "assets")
And it seemed to work. On WEBRick, on development, it worked beautifully.
Now I deployed successfully to a server, precompiled the assets, and thought I was ready to go.
the directory
/public/assets/
was created. Everything in "app/assets/javascripts", "app/assets/stylesheets" and "app/assets/plugins" were precompiled to public/assets
WHAT WORKED
app/assets/javascripts/login.js
was able to be accessed in a view that had
<%= javascript_include_tag 'login.js' %>
WHAT DIDN'T WORK
Files that belonged to "plugins".
app/assets/plugins/myPlugin1/somefile.js
was precompiled to
public/assets/myPlugin1/somefile.js
But when I ran
<%= javascript_include_tag 'plugins/myPlugin1/somefile.js' %>
it tries to access
/javascripts/plugins/myPlugin1/somefile.js
when the correct path, according to my experience in development, would be:
/myPlugin1/somefile-(some hex hash).js
So, as you can see, in production I'm experiencing the same issue as when I haven't added
config.assets.paths << Rails.root.join("app", "assets")
to application.rb
What could be the problem?
回答1:
You could go this way:
Dir.glob("#{Rails.root}/app/assets/plugins/**/").each do |path|
config.assets.paths << path
end
Or set each plugin, one by one like:
config.assets.paths << Rails.root.join("app", "assets", "plugins", "myPlugin")
But if you have subdirectories on that myPlugin directory would not load every file. So the first option might be better for you.
