    <p>When querying for an non-existing post in my controller via</p> <pre><code>@post = Post.find_by_id(params[:id]) </code></pre> <p>I get ActiveRecord::RecordNotFound. But when I do the same in the rails console I get nil returned.</p> <p>I also tried <code>find_by_id!</code> (note the exclamation point) that is supposed to trigger a 404, but it still just gives me ActiveRecord::RecordNotFound.</p> <p>I found out that a gem could cause this kind of problem (see question: <a href="https://stackoverflow.com/questions/12148785/rails-find-by-id-raises-exception">Rails Find_by_id raises exception</a>), so my question is how do I figure out which gem that I use could cause the same problem?</p> <p>This is my Gemfile</p> <pre><code>source 'https://rubygems.org' gem 'rails', '3.2.7' gem 'pg' gem 'jquery-rails' gem 'fancybox-rails', :git =&gt; 'https://github.com/sverigemeny/fancybox-rails' gem 'bcrypt-ruby', '~&gt; 3.0.0' gem 'omniauth-twitter' gem 'omniauth-facebook' gem 'omniauth-google-oauth2' gem 'validates_email_format_of', :git =&gt; 'git://github.com/alexdunae/validates_email_format_of.git' gem 'cancan' gem 'thin' gem 'chronic' gem 'simple_form' gem 'twitter' gem 'kaminari' group :assets do gem 'sass-rails' gem 'compass-rails' gem 'coffee-rails' gem 'uglifier', '&gt;= 1.0.3' end group :development do gem 'quiet_assets' gem 'faker' end </code></pre> <p>I don't see how I can just disable one by one until I find the Gem that might causes this problem because I will most likely trigger many other errors due to Gem dependencies in the process.</p> <p>Anyone have any idea of how I should go about this?</p> <p><strong>Update</strong> Here is the full stacktrace:</p> <pre><code>ActiveRecord::RecordNotFound in PostsController#edit Couldn't find Post with id=123202 activerecord (3.2.7)

    1. COCan you post a stacktrace? Are you sure it's the line `@post = Post.find_by_id(params[:id])` that's causing this error? `find_by_id` without an exclamation mark shouldn't be raising an exception, only `find_by_id!` should be doing that...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
