bootstrap-datepicker-rails | Twitter Bootstrap , integrated with Rails assets | Frontend Framework library

UPDATED: Per Michael's suggestion/comment, I am reformatting below display code. I also made the minor fixes on code like rails which was commented out and also not latest. The history of the Gemfile dates back to Michael Hartl's RoR tutorial - I had made an app using it but not touched in last 2 years.

Now I have run bundle update which resulted in a lot of things getting updated which was nice. However at the end it gave me the same error as before - see below pls. Any further advice would be great pls. Thank you.

I'm trying to push some modifications of my Ruby on Rails web to Heroku but it says "push rejected". The error comes after "Detecting rake tasks" and here's the message:

I have some strange behavior happening with bootstrap datepicker in a rails form. I'm using form_for in a partial for edit and new. When editing, the calendar shows perfectly when clicking on the date field but when adding a new record, the calendar is covered over by a dropdown list containing about 6 dates recently entered via the form. The calendar control is also open under the list. I can see the right edge of it. Also, when I move the browser window around or go to another open app and then back to the browser, only the calendar is there...the drop down list disappears. So odd!

I've been searching for a solution for several weeks and have scoured the internet and the datepicker documentation but just can't figure this out. Any guidance appreciated!

Here is the text_field within my form_for.

How to link fullcalendar with datepicker, so that it looks like on the picture below using Rails 5 and gem 'bootstrap-datepicker-rails' + gem 'fullcalendar-rails'?

Recently I upgraded my project to Rails 5 and I'm going crazy with the assets pipeline when trying to upload everything to Heroku.

The issue is the following: I have a collection of Ejercicios and, when u click on one of them, the app should show its information, including an image. The routes to the images are stored in my db like this img1: "ejercicios/abdominales/1_4_I1.bmp". That file, for example, would be on app/assets/images/ejercicios/abdominales/1_4_I1.bmp.

The related view show.html.haml prints the images like this: = image_tag(@ejercicio.img1) if @ejercicio.img1?.

It worked perfectly on local but not in production in Heroku, so read about the assets pipeline in order to make it work. So I changed my show.html.haml like this: = image_tag asset_path(@ejercicio.img1) if @ejercicio.img1? and I added the lines the tutorial mentions in Gemfile and application.rb. The executed bundle install and bundle exec rake assets:precompile RAILS_ENV=production, added the new 'public' folder to my git, committed and pushed my git, and finally pushed everything to heroku.

But it doesn't work, the 'alt' of the image is shown. Using the inspector I can see that the images in the html follow the normal url to the image and not the one with the fingerprint, so the helper asset_path seems not to be working properly.

Here's my production.rb in config/environments
