I'm trying to deploy my app for the first time in heroku and I'm encountering a weird bug. When I try to run heroku rake db:migrate, i see this error :
rake aborted! StandardError: An error has occurred, this and all later
migrations canceled:
PG::UndefinedTable: ERROR: relation "companies" does not exist

)
I have verified a thousand times my migrations files Users & Companies but nothing seems bad. So I really don't know what to do. I also try all the database reset etc..
Like in this answer for example. But nothing is working for me. Anyone have seen this before ?? I'm really desperate at this point.
PS: And I also remove made the pg and sql3 changes.
So I give you my code if it can be useful to discover the problem

The error message suggests that you're trying to create a reference to companies on the users table but the companies table doesn't yet exist. Try making sure the order of your migrations is such that companies is created before users. You can also try just loading the schema all at once rather than migrating one at a time, with heroku run rake db:schema:load.
DISCLAIMER: rake db:schema:load will wipe all of your data. It is best used for setting up a new database. Never run it against a production database that already contains critical data. Once you have data you will need to do incremental migrations.
Create the database first with rake db:create.

I created the following Active Record Schema using migrations but the relationships don't correspond to the schema. I've tried resetting, dropping, creating and migrating but in Rails C if i create a User u.User.create!(...), and then query u.groups or u.genres I get 'undefined method'
Thanks for your help

end
add_foreign_key "genres", "users"
add_foreign_key "groups", "users"
add_foreign_key "playlists", "groups"
end
here are the models:
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
#before_action :authenticate_user!
has_and_belongs_to_many :genres, :through => :genres_users
has_and_belongs_to_many :groups, :through => :groups_users
include Enumerable
end
class Genre < ApplicationRecord
has_and_belongs_to_many :users, :through => :genres_users
end
class Group < ApplicationRecord
has_and_belongs_to_many :users, :through => :groups_users
has_one :playlist
end
class Playlist < ApplicationRecord
belongs_to :group
end
The relationship is that Groups have users, users have genres (favourite genres!), these are has and belongs to relationships through join tables (multiple genres per user and multiple groups per user). Every group has a playlist, and there will be multiple playlists
[Edited after clarification from OP]
The relationship is that Groups have users, users have genres (favourite genres!), these are has and belongs to relationships through join tables (multiple genres per user and multiple groups per user). Every group has a playlist, and there will be multiple playlists
First off, you don't need a user_id column on groups or genres as that's not how the setup should work.
class Genre < ApplicationRecord
has_many :favorite_genres
has_many :users, through: :favorite_genres
[... other stuff]
end
class User < ApplicationRecord
has_many :group_memberships
has_many :groups, through: :group_memberships
has_many :favorite_genres
has_many :users, through: :favorite_genres
[... other stuff]
end
class Group < ApplicationRecord
has_many :group_memberships
has_many :users, through: :group_memberships
has_many :playlists
[... other stuff]
end
class Playlist < ApplicationRecord
belongs_to :group
end
class GroupMemberships < ApplicationRecord
belongs_to :user
belongs_to :group
[... other stuff]
end
class FavoriteGenres < ApplicationRecord
belongs_to :user
belongs_to :genre
[... other stuff]
end
So you'd drop the user_id column in groups. The connection happens in :group_memberships (the table formerly known as users_groups), which is a user_id, a group_id, and then you can have additional metadata columns as you need them (e.g. admin boolean/role, etc)
. This is called a "Has Many Through" relationship (http://guides.rubyonrails.org/association_basics.html#the-has-many-through-association)
Likewise, a user's favorite genres is setup with a through relationship. So you'll have a separate database table AND model file for those through joins.
I don't think you need your add_foreign_key calls at all at this level, nor many of your indexes. You'll probably do more eager loading or possibly add indexes on the thorugh join tables and you'd do those like this in the schema:
t.index ["user_id", "genre_id"], name: "index_favorite_genres_on_user_id_and_genre_id"
Remember that belongs_to now creates a validation for that to be present in 5.x. You can override this by adding optional: true on that line in the model, e.g. belongs_to :foo, optional: true
So all that being said, here's your new schema:
create_table "genres", id: :serial, force: :cascade do |t|
t.string "tag"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "groups", id: :serial, force: :cascade do |t|
t.string "name"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
create_table "favorite_genres", id: false, force: :cascade do |t|
t.bigint "user_id", null: false
t.bigint "genre_id", null: false
end
create_table "groups_memberships", id: false, force: :cascade do |t|
t.bigint "user_id", null: false
t.bigint "group_id", null: false
end
create_table "playlists", id: :serial, force: :cascade do |t|
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "name"
t.string "link"
t.text "description"
t.bigint "group_id"
t.index ["group_id"], name: "index_playlists_on_group_id"
end
create_table "users", id: :serial, force: :cascade do |t|
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "email", default: "", null: false
t.string "encrypted_password", default: "", null: false
t.string "reset_password_token"
t.datetime "reset_password_sent_at"
t.datetime "remember_created_at"
t.integer "sign_in_count", default: 0, null: false
t.datetime "current_sign_in_at"
t.datetime "last_sign_in_at"
t.string "current_sign_in_ip"
t.string "last_sign_in_ip"
t.string "name"
t.string "token"
t.date "birthday"
t.string "link"
t.string "playlistId"
t.string "country"
t.index ["email"], name: "index_users_on_email", unique: true
t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
Give that a whirl (I haven't built this in an app, so there may be some errors in the code) and you should now be able to do your console run:
u = User.create([values])
u.genres (should return nil until you create some relationships)
etc.
I have the following models:
User:
User
has_and_belongs_to_many :user_jobs, foreign_key: "user_id", class_name: "Job"
has_many :jobs, through: :locations
has_many :customers, through: :locations
has_and_belongs_to_many :locations

has_and_belongs_to_many :users
has_and_belongs_to_many :customers

With this model structure I can query the jobs model in two different ways. First user.user_jobs and user.jobs. Both of these queries return two different result sets. I need to be able to do the same thing with the customers. I can currently query user.customers but I do not know what syntax I should use to make user.user_customers work so that the query joins with the users' related jobs and then grabs the customers related to those jobs. My current query joins the users' locations and grabs the customers associated with those locations. Thanks in advance!
has_many :user_job_customers, through: :user_jobs, source: 'customers'
has_many :location_customers, through: :locations, source: 'customers'
I guess you need :source option
Hello I'm getting a rollback transaction when I try to create a Bid from the rails console. These are my models:

Although I tried to create like so: Bid.create(amount: 500, user_id: 1, product_id:6) it doesn't save because of the rollback transaction.
Thanks in advance
The code you posted doesn't really help. You should also add the logs.
Before posting any logs, I'd try b = Bid.new(amount: 500, user_id: 1, product_id: 6) and b.save in the console. After that, do b.errors and see what's causing the rollback.
EDIT: Add .save.
EEDIT: For anyone experiencing the same problem, the issue was with the Bid model referencing a Product wrong.
When using belongs_to, the model should be singular, not plural. Ex: belongs_to: apple not belongs_to: apples
I've built a rails app and on pushing it up to heroku and running heroku run rake db:migrate i receive the error:

The relationship I have setup is for users to follow users and be followed. It works perfectly in development. This is the first time i've had this error and can't find a solution. Please see the rest of my code below.

Please excuse the messy model, it would usually be in a helper method but for this post it's here. If anyone has any ideas please let me know! Thanks
I am new to rails. Everything is working fine locally but after deploying on heroku its giving me the above error.
Here is the posts_controllers action:
def new
#post = current_user.posts.build
end
and here is the schema.rb file content:
ActiveRecord::Schema.define(version: 20160516214156) do
create_table "comments", force: :cascade do |t|
t.text "comment"
t.integer "post_id"
t.integer "user_id"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end
add_index "comments", ["post_id"], name: "index_comments_on_post_id"
add_index "comments", ["user_id"], name: "index_comments_on_user_id"
create_table "posts", force: :cascade do |t|
t.text "description"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
t.string "image_file_name"

end
add_index "users", ["email"], name: "index_users_on_email", unique: true
add_index "users", ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
end
I had the same error.
To solve the problem, I specified :foreign_key of has_many relation.
My case:
class Assay::Attempt::Answer < ActiveRecord::Base
belongs_to :assay_attempt, class_name: 'Assay::Attempt'
end
class Assay::Attempt < ActiveRecord::Base
has_many :answers, foreign_key: :assay_attempt_id # there wasn't foreign_key option
end
I came across this as well on Rails 4.2.0, in my case everything seemed to be ok, since I had the foreign_key specified, what fixed the issue was when the foreign_key and foreign_type were specified as a string, not as a symbol:
has_many :answers, foreign_key: :assay_attempt_id #this was not working
has_many :answers, foreign_key: 'assay_attempt_id' #this was ok
