为什么Heroku返回'devise / sessions.js没有预编译'？

I'm deploying a Rails 3.2 app to Heroku. I'm precompiling assets locally as per https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar.

我正在向Heroku部署Rails 3.2应用程序。我根据https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar在本地预编译资产。

But I'm getting

但我得到了

ActionView::Template::Error (devise/sessions.js isn't precompiled):

Has anyone else encountered this?

有人遇到过这种情况么?

What is the correct way to ensure Devise javascripts are precomiled.

什么是确保Devise javascripts预先推出的正确方法。

Thanks!

Thank you for all the suggestions. After a bit of thinking, I realize that the issue was down to how the app was configured to call controller-specific javascript. IN case anyone else runs into this issue, here's what I did.

谢谢你提出的所有建议。经过一番思考后,我意识到问题在于应用程序如何配置为调用控制器特定的javascript。如果有其他人遇到这个问题,这就是我做的。

I had been loading controller-specific .js via the following tag in the layout file.

我一直在布局文件中通过以下标记加载特定于控制器的.js。

<%= javascript_include_tag "application", params[:controller] %>

Problem is, this fails if a particular cotroller.js file does not exist. In my case, the login page failed as I had not created a devise/sessions.js file.

问题是,如果特定的cotroller.js文件不存在,则会失败。在我的情况下,登录页面失败,因为我没有创建devise / sessions.js文件。

I could have created this file, but I felt this was a messy approach. I don't like the idea of having a lot of empty files lying around.

我本可以创建这个文件,但我觉得这是一个混乱的方法。我不喜欢有很多空文件的想法。

Instead I am explicitly calling controller-specific javascripts from the view

相反,我明确地从视图中调用特定于控制器的javascripts

<% javascript 'controller.js' %>

Using the following helper in application_helpers

在application_helpers中使用以下帮助程序

def javascript(*files)
    content_for(:head) { javascript_include_tag(*files) }
end

Seems to be working fine so far.

到目前为止似乎工作正常。

Thanks again for the suggestions.

再次感谢您的建议。

My solution:

<%= javascript_include_tag "application", controller_name if controller_name != "sessions" %>

#3

Try running rake assets:precompile.

尝试运行rake资产:预编译。

Try adding this to your config/environments/production.rb :

尝试将此添加到config / environments / production.rb:

config.assets.precompile += %w( *.css *.js )

Or specify your file.

或者指定您的文件。
