Using the code below to reset & reseed the DB
task init: [:environment, 'db:migrate:reset', 'db:seed']
db:seed creates a few users & few objects. It also updates role for few users.
db:seed throws following error NoMethodError: undefined method 'role' for User.
There is a migration file which adds role column to User table.
Unable to resolve this. Tries to write separate task for db:seed. Tried following
task init: [:environment, 'db:migrate:reset', 'db:seed'] do
Rake::Task['db:seed'].invoke
end
Same error as before. Why is column from migration file isn't loaded for db:seed or I am missing something here?
Error log:
NoMethodError: undefined method `role' for #<User:0x00007fd5ecb239e0>

Using db:reset solved the issue. i.e.
task init: [:environment, 'db:reset']
db:reset executes db:drop, db:setup.
db:setup executes db:schema:load whereas db:migrate:reset executes db:migrate. And db:schema:load is faster than db:migrate.
Not sure why db:migrate causes the issue.
As Sergio suggested stale cache could be the cause. And his suggestion in the comments User.reset_column_information loads all the columns.

I've got a (brand new) Rails 5 project that's throwing errors when I try to run migrations.
(I'm running Ruby 2.2.4 on a Raspberry Pi using PostgreSQL 9.4, but the same error message popped up when I first tried running the migration with SQLite.)
So far, the only migration I've got is pretty basic:
class CreateAuthors < ActiveRecord::Migration[5.0]
def change
create_table :authors do |t|
t.string :username
t.timestamps
end
end
end
This results in the following output when I run rake db:migrate.
pi#raspberrypi:~/projects/gnn $ rake db:migrate
== 20160915091621 CreateAuthors: migrating ====================================
-- create_table(:authors, {})
-> 0.0283s
== 20160915091621 CreateAuthors: migrated (0.0287s) ===========================

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
Edit: Maybe worth saying that rake db:create ran fine.
Here's my database.yml file as well, in case I've missed something there (I'm pretty green with PostgreSQL)
default: &default
adapter: postgresql
encoding: unicode
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: gnn_dev
username: gnn
password: Lorem123
host: localhost
port: 5432
I have met the same issue in the middle of development. Have found the reason.
In my case I added a new gem 'imgurapi', that adds 'to_hash' to Array objects
class Array # :nodoc:
# Skipped code
def to_hash # :nodoc:
inject({}) { |hsh, (k,v)| hsh[k] = v ; hsh }
end unless method_defined?(:to_hash)
end
As result the calling the code exec_query(sql, name, binds) in gems/activerecord-5.0.0.1/lib/active_record/connection_adapters/postgresql/database_statements.rb:135:in 'exec_insert' converts binds variable from Array to Hash type by the reason, that's good described here https://makandracards.com/makandra/36013-heads-up-ruby-implicitly-converts-a-hash-to-keyword-arguments. As result we have the error, because this conversion is unexpected.
Solution
Find the gem that defines 'to_hash' method for Array and get rid of this definition. Good luck!
Remove [5.0] from the first line .
class CreateAuthors < ActiveRecord::Migration
def change
create_table :authors do |t|
t.string :username
t.timestamps
end
end
end
thanks
Remove [5.0] from the first line
Restart the Server and run rake db:migrate.
May be this will helps you.
I'm having a strange problem executing rake db:migrate

-- create_table(:movies)
-> 0.0033s
== 20141127213559 CreateMovies: migrated (0.0034s) ============================

ArgumentError: wrong number of arguments (1 for 0)
Tasks: TOP => db:migrate
(See full trace by running task with --trace)
What I did was:
rails generate model Movie
And then edit the migration CreateMovies
class CreateMovies < ActiveRecord::Migration
def up
#drop_table :movies
create_table :movies do |t|
t.string :title
t.string :rating
t.text :description
t.datetime :release_date
# Add fields that let Rails automatically keep track
# of when movies are added or modified:
t.timestamps
end
end
def down
drop_table :movies
end
end
This is the output of executing the command with --trace

Tasks: TOP => db:migrate
Any help would be really appreciated. Thanks.
If you are using Rails 4.2.0.beta4, ActiveRecord will require arel gem. Add the following to your gem file
gem 'arel', '6.0.0.beta2'
and run
bundle install
You may get below error message
You have requested:arel = 6.0.0.beta2
The bundle currently has arel locked at 6.0.0.
Try running `bundle update arel`
then
bundle update arel
Now you should able to run migration.
Here you may find similar and explanatory answer: Can't migrate database after scaffold. Section 2.2 Ruby on Rails Tutorial Michael Hartl
Maybe you should execute this after create movies table:
generate migration AddFieldsToMovies newfield:type
This generates the correct migration, see this:
http://edgeguides.rubyonrails.org/active_record_migrations.html#changing-tables
I'm working through the Hartl ruby on rails tutorial (section 2.2), and I'm having trouble migrating the database. Everything seemed to be working, and then I ran rails generate scaffold User name:string email:string Afterwards I tried to run bundle exec rake db:migrate and got the below error message:
$ bundle exec rake db:migrate

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
I've tried going back to an earlier commit and running everything again but I get the same error message. Are there any more files that I should add that can help with this?
I just ran into this as well. This is due to ActiveRecord 4.2.0.beta4 passing a parameter to Arel::Nodes::BindParam.new. Arel 6.0.0 was just released today. In this version, BindParam does not accept any parameters in it's initalizer.
ActiveRecord has already fixed this on the master branch. Until beta5 is released you'll need to lock your Gemfile to gem 'arel', '6.0.0.beta2'.
with above solution of changing gemfile.
gem 'arel', '6.0.0.beta2'
I got below error message.
You have requested:arel = 6.0.0.beta2
The bundle currently has arel locked at 6.0.0.
Try running `bundle update arel`
After
bundle update arel
it worked
I've solved this with
rake db:reset
After that
rake db:migrate
worked.
I am using Rails4 and ruby2.0.0. I pushed my app on Heroku & I m getting this error when I run heroku run rake db:seed

You are creating devise users in your seed file. Devise automatically sends some emails E.g. email_confirmation.
So you have to set up a proper ActionMailer for production Environment. You might be using an another heroku service for that. E.g mailgun
You can also bypass devise email_confirmation in your seed file.
I guess this is another reason I should be backing up my work with GitHub, but alas, I have not been.
The migration I want to rollback is this:
class AddAssociationToTables < ActiveRecord::Migration
def change
add_column :articles, :user, :belongs_to
end
end
Which obviously isn't well formed because it seems to have totally removed my article table from the database.
I tried rake db:rollback:status and there is nothing 'missing' or anything.
I'm gonna skip copy-pasting the entire trace.
I tried to make a counteracting migration and run that. This is what I wrote:
class RemoveAssociationFromArticle < ActiveRecord::Migration
def change
remove_column :articles, :user, :belongs_to
end
end
But when I tried to run rake db:migrate with this I got what looks like the same error.
EDIT ok here's the whole trace for the rollback first, and then the migrate attempt
== AddAssociationToTables: reverting =========================================
-- remove_column(:articles, :user, :belongs_to)

Tasks: TOP => db:migrate
(See full trace by running task with --trace)
The third parameter should be the type of column.
The correct syntax is:
add_column :articles, :user_id, :integer
The :belongs_to parameter may causing conflict with ActiveRecord methods!
If it did not migrate properly in the first place, don't worry about rolling back. Just fix the migration and try to migrate again.
Your migration should be:
add_column :articles, :user, :references
The belongs_to is for in the model class, and not in the migration. If it gets to a point where you can't do anything, you can always recreate the database to start fresh (and lose all data).
$ rake db:drop db:create db:migrate
Start using version control, and read through all of this slowly and carefully at some point in life http://guides.rubyonrails.org/migrations.html
