+# Temporarily Turn Off Pending Migrations Error
+
+Whenever I'm working on an end-to-end feature in a Rails app, soon or later I
+am going to see the _Pending Migrations_ error page. I try to visit one of the
+routes in the browser and the Rails app serves this error page instead of my
+actual request response.
+
+This is typically what I want. If there are migrations just sitting there that
+haven't been run yet, that's probably an issue. Maybe I just pulled down the
+latest changes from my teammates. The app isn't going to work properly without
+whatever schema changes are prescribed in those pending migrations.
+
+The thing to do is run those migrations.
+
+In some special cases though, I know what I'm doing and I would like to operate
+my app locally with specific migrations not yet applied.
+
+To skip the error, I can change this `config/environments/development.rb`
+setting from:
+
+```ruby
+config.active_record.migration_error = :page_load
+```
+
+to:
+
+```ruby
+config.active_record.migration_error = false
+```
+
+I just need to make sure to switch it back when I'm done.
