    <p>I have researched this topic, but am afraid I have too little experience with Git and may be causing more problems by trying out different things, so I am posting to find out the best way to revert to a previous state of my App.</p> <p>I committed the changes and deleted the previous branches, but not before I backed up the app locally on an external drive.</p> <p>Everything was working fine (function-wise), as evidenced by my deployment to Heroku, which is still working, prior to my most recent changes.</p> <p>I failed to create a branch for the new changes, something I will never do again, and I was working off the master. False confidence...</p> <p>So, since everything went so horribly wrong, I decided to copy over the backed up App and start new... but that didn't work.</p> <p>I think it could be a simple matter of reverting to uncommitted changes on the master, but I am a little frozen with fear that I may make a misstep.</p> <p>Can you help???</p> <p>I am working on rails 3.2, ruby 1.9.3, git 1.7.4.4</p> <p>Update</p> <hr> <p>I have used git reset --hard HEAD and now terminal tells me HEAD is now at 820f417 micro.</p> <p>Problems I'm having are:</p> <p>I don't know how this may or may not change files I have edited inside textmate and saved to the hard drive.</p> <p>When I open the app in the browser, I am getting the error: </p> <pre><code>ActiveRecord::StatementInvalid in StaticPagesController#home Could not find table 'users' </code></pre> <p>Trace: app/helpers/sessions_helper.rb:46:in <code>user_from_remember_token' app/helpers/sessions_helper.rb:16:in</code>current_user' app/helpers/sessions_helper.rb:9:in <code>signed_in?' app/controllers/static_pages_controller.rb:4:in</code>home'</p>

    1. COWhat have you committed? If the working version was committed to git, all you need is to fetch that version. Forget about the backup in that case. That's what you have version control for.

    2. COAgreed re. hard drive. Copying your repository to an external source will simply confuse matters—as it has already done. If you are worried about "back-ups", create a Github repository and push your local changes to it. This has the added benefit of giving you a nice UI for your seeing your commit tree on Github.com.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
