    <p>This is driving me insane! This code used to work fine, but as of a few weeks ago it stopped working, and I can't work out why. Basically a Game has many Patches. The error occurs in my PatchesController, but its reproducible in the rails console like this:</p> <pre><code>first_game = Game.find(:first) first_game.patches </code></pre> <p>As soon as I use the patches method, I get this:</p> <pre><code>ActiveRecord::StatementInvalid: SQLite3::SQLException: no such column: patches.game_true: SELECT * FROM "patches" WHERE ("patches".game_true = 1) from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:221:in `rescue in log' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:204:in `log' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite_adapter.rb:172:in `block in execute' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite_adapter.rb:417:in `catch_schema_changes' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite_adapter.rb:172:in `execute' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/sqlite_adapter.rb:320:in `select' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:7:in `select_all' from /project_root/vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/query_cache.rb:62:in `select_all_with_query_cache' from /project_root/vendor/rails/activerecord/lib/active_record/base.rb:664:in `find_by_sql' from /project_root/vendor/rails/activerecord/lib/active_record/base.rb:1578:in `find_every' from /project_root/vendor/rails/activerecord/lib/active_record/base.rb:618:in `find' from /project_root/vendor/rails/activerecord/lib/active_record/associations/association_collection.rb:60:in `find' from /project_root/vendor/rails/activerecord/lib/active_record/associations/association_collection.rb:400:in `find_target' from /project_root/vendor/rails/activerecord/lib/active_record/associations/association_collection.rb:354:in `load_target' from /project_root/vendor/rails/activerecord/lib/active_record/associations/association_proxy.rb:140:in `inspect' from /usr/local/bin/irb:12:in `&lt;main&gt;' </code></pre> <p>Now that SQL should really say 'WHERE patches.game_id = 1', unless I'm going mad. I have no idea why it's generating that SQL!</p> <p>Here's models/game.rb:</p> <pre><code>class Game &lt; ActiveRecord::Base has_many :patches end </code></pre> <p>Here's models/patches.rb:</p> <pre><code>class Patch &lt; ActiveRecord::Base belongs_to :game end </code></pre> <p>And the patches table has 'game_id' in the table, and 3 entries, all for the first game. If I get one of the Patches and go my_patch.game, it returns the Game object it belongs to, with no problems. Any help would be greatly appreciated!</p>

    1. COIf you manually set the key on the association, does it work? Understanding that you SHOULDN'T have to set it, I'm just curious if we can figure out where the error is at.

    2. COPatch.find(:all, :conditions => {:game_id => 1}) works fine! first_game.patches.find(:all, :conditions => {:game_id => 1}) gives the same error, and generates this SQL: SELECT * FROM "patches" WHERE ("patches".game_true = 1 AND ("patches"."game_id" = 1))

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).
