Anyway, I've done the Heroku getting started tutorial, uploading a clone git repo, and this works fine. I'm now trying to accomplish this with some of my own code, but struggling. First, I go to my app directory in bash. Then I run heroku create . This is successful. I then run git push heroku master as instructed in the tutorial, and I receive the following errors: error: src refspec

问题 Can I connect to a Heroku Postgres database via an web/application without the risk of dropping a table? I'm building a Heroku application for a third party which uses Heroku Postgres for the backend. The third party are very security sensitive so I'm looking at applying "Layered security" throughout the application. So for example checking for SQL injection attacks at the web/application layer.

问题 I installed a bootstrap theme and everything is working well locally. However, when I went to push to heroku, my app couldn't find the fonts. I precompiled the assets and pushed to heroku, but no icons. So, I made my development environment like heroku with the following in development.rb: config.assets.debug = true # Disable Rails's static asset server (Apache or nginx will already do this). config.serve_static_assets = true # Compress JavaScripts and CSS. config.assets.js_compressor =
