I have been in trouble with this error caused when I started to code my tests on ruby on rails.
I have search in the web but the posts that I have found did not help me. I leave the references:
Rails: Relation does not exist for reference with class name in production
https://github.com/rails/rails/issues/29206
PG undefinedtable error relation users does not exist
This is the test that I made:
App/test/models/material_test.rb
require 'test_helper'
class MaterialTest < ActiveSupport::TestCase
test "the truth" do
assert true
end
end
When I try to execute it using:
rails test
I got the following error:
# Running:

I have run reset database and run migrations a few times...
Any ideas?
I had gems and files that needed to be deleted. :(
I used the command:
$ rails g model Equipment
and rails performed the following:
invoke active_record
create db/migrate/20160822040448_create_equipment.rb
create app/models/equipment.rb
invoke test_unit
create test/models/equipment_test.rb
create test/fixtures/equipment.yml
As you can see, the migration is singular! So I renamed the migration file and the table name as follows:
class CreateEquipments < ActiveRecord::Migration
def change
create_table :equipments do |t|
# ...
end
end
end
Now, after running $ rake db:migrate starting Rail's console $ rails c, it errors out saying it cannot find the table when I try to initiate an Equipment:
>> Equipment.new
PG::UndefinedTable: ERROR: relation "equipment" does not exist
LINE 5: WHERE a.attrelid = '"equipment"'::regclass

pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod

ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"equipment"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "equipment" does not exist

ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"equipment"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
I was able to patch it up by adding the following line to the model:
class Equipment < ActiveRecord::Base
self.table_name = 'equipments'
# ...
end
but, although that fixes the issue, I want to know what's causing the problem to begin with.
Final Note: I tried running #pluralize method on the console, and it wouldn't pluralize the string 'Equipment' in there either:
>> 'Equipment'.pluralize
=> "Equipment"
>> 'door'.pluralize
=> "doors"
Equipment does not have a plural

This is expected behaviour for such words.
I'm trying to use the Ruby gem Fuzzily in my rails application, but am getting this error
relation "trigrams" does not exist
I followed all the instructions from https://github.com/mezis/fuzzily
Here's my code
trigram.rb
class Trigram < ActiveRecord::Base
include Url::Model
include Fuzzily::Model
end
url.rb
class Url < ActiveRecord::Base
fuzzily_searchable :short_url
end
add_trigram_mode.rb
class AddTrigramsModel < ActiveRecord::Migration
extend Url::Migration
extend Fuzzily::Migration
trigrams_owner_id_column_type = :uuid
end
I did a rake db:migrate. When I execute this in rails console, I get:
Url.find_by_fuzzy_short_url('sojdgl')
Url Load (1.4ms) SELECT "urls".* FROM "urls" ORDER BY "urls"."id" ASC LIMIT 100
PG::UndefinedTable: ERROR: relation "trigrams" does not exist
LINE 5: WHERE a.attrelid = '"trigrams"'::regclass
^
: SELECT a.attname, format_type(a.atttypid, a.atttypmod),
pg_get_expr(d.adbin, d.adrelid), a.attnotnull, a.atttypid, a.atttypmod

ON a.attrelid = d.adrelid AND a.attnum = d.adnum
WHERE a.attrelid = '"trigrams"'::regclass
AND a.attnum > 0 AND NOT a.attisdropped
ORDER BY a.attnum
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR: relation "trigrams" does not exist
LINE 5: WHERE a.attrelid = '"trigrams"'::regclass
I named the migration file incorrectly. I works when I changed it to 20150830110623_add_trigrams_model.rb
We are using rails (4.0.4), ruby (2.0.0p247) and activerecord-postgis-adapter (0.6.5) and singular table names set in ./config/environment.rb (ActiveRecord::Base.pluralize_table_names = false)
This works great in development and test environments.
In the production environment it works for every table but one, project. For this table we are seeing an error in the controller index.
I regenerated the scaffolding and was able to pinpoint the problem the this lin in the project_controllers:
set_rgeo_factory_for_column(:location, RGeo::Geographic.spherical_factory(:srid => 4326))
The error is:

Seems really odd it works in every other environment and in production it only fails for one table, as well as associated tables.
Any suggestion appreciated.
I found two solutions:
remove set_rgeo_factory_for_column from the model, I was using the default factory anyways
Explicitly specify the table name, self.table_name. This is odd since i set ActiveRecord::Base.pluralize_table_names = false
Env: Rails 3.2.11
Added paper_trail gem.
Note that I already used that gem and I never had a problem but this time I am getting an error and I can't find out why.
In my Model:
class User < ActiveRecord::Base
has_paper_trail :versions => :paper_trail_versions
...
end
The error:
User Exists (0.6ms) SELECT 1 AS one FROM "users" WHERE ("users"."pseudo" = 'joel' AND "users"."id" != 21) LIMIT 1

)
any leads on how to troubleshoot this?
Have you followed the installation instructions:
Install PaperTrail as a gem via your Gemfile:
gem 'paper_trail', '~> 2'
Generate a migration which will add a versions table to your database.
bundle exec rails generate paper_trail:install
Run the migration.
bundle exec rake db:migrate
Add has_paper_trail to the models you want to track.
