dropdown-toggle在heroku上不起作用。 不知道为什么

Question

I am facing a problem whereby the dropdown menu and also flash[:notices] are not responding to clicks. Tried the solution here Why does dropdown-toggle (bootstrap) not work on heroku? and other variants of it. ie moving require bootstrap up but it doesnt work.

However, when I tried to run rake assets:reset locally and in the heroku app. The rake is aborted, cause dont know how to build task 'assets:reset'.

Then I gave precompile a shot locally, and there is no response, then I tried doing this for heroku and get the error below.

ChickenSmitten:fundspace shengyeong$ heroku run rake assets:reset --app fundspace-session-staging
Running `rake assets:reset` attached to terminal... up, run.4723
rake aborted!

When I dig more info like going through this How can I reset my asset pipeline in Rails? , I realized that this is unfamiliar territory. Need advise.

Thanks.

Answer 1

bundle exec rake assets:precompile
