Try to reset your database first
heroku pg:reset DATABASE
then

i would love to know why it did so and how to fix it
By looking at error message I suspect two things happened here:
You already had users table (because new migration has change_table(:users), not create_table(:users) - devise generator recognize that)
You ran $ rails generate devise command and you didn't inspect autogenerated migration file.
You were supposed to remove line
t.string :email, null: false, default: ""
from 20180311182801_add_devise_to_users.rb file

Index name on a table should be unique. So this is an error from db as the the index already exists. Please drop the index on the table of the db before migration or you can remove the add_index in migration if the index is already ok in the table

Before this I use bundle update and after and nothing, and when I put "rake-T", db Migartion is on the tasks, when I try with --trace, pass the same.

Does anyone know how to solve this problem?
In the migration file I have:
class CreatePosts < ActiveRecord::Migration
def change
create_table :posts do |t|
t.string :title
t.strind :
t.text :body
t.timestamps
end
end
end
I am pretty sure what is happening is you are inserting a space in there when you type it out. It needs to be
rake db:migrate
not
rake db : migrate
That error message is pretty common when there is a spelling error or some other kind of typing error when running the command.
Your migration has a typo as well, should be this
class CreatePosts < ActiveRecord::Migration
def change
create_table :posts do |t|
t.string :title
t.text :body
t.timestamps
end
end
end
Rake is a software task management tool, similar to Make, etc. in other systems
The generic syntax is
rake namesapce:task
In your case it is
rake db:migrate
Try doing rake db:reset if you want to rebuild your db again. It does 4 things for you
rake db:drop
rake db:create
rake db:migrate
rake db:seed
Some of my rSpec tests are failing and I suspect it's due to the test database not being cleared out. When I try to run rake db:test:prepare, I'm getting the error below (i'm in Rails 3.2). Clearly, this looks like some kind of Postgres issue, looks like the rake task is trying to drop the test database so it can repopulate it. Production database schema loads fine.
I've looked for the rake task in lib/tasks/ but I haven't been able to find it. Anyone have any idea on what's going on?

Figured it out. My database.yml file for the development environment was set like this:
database: <%= ENV['DATABASE_NAME_TEST'] %>
The rake task was looking for an environmental variable that did not exist.
i'm getting the following output when deploying:
cap aborted!

The deploy has failed with an error: #<NoMethodError: undefined method `run' for main:Object>
i'm using Capistrano Version: 3.2.1 (Rake Version: 10.3.2).
the deploy works fine but i created a after deploy task to modify the owner of the deployed release which looks so:
namespace :deploy do
task :permissions do
run "chown -R :#{fetch(:group)} #{deploy_to} && chmod -R g+s #{deploy_to}"
end
end
after :deploy, "deploy:permissions"
vars are defined correctly (i fixed that error before) but i get this missing method error for the run method and i dont know why.
Your code uses 2.x syntax, while your version is 3.x. In 3.x, the syntax looks like this:
namespace :deploy do
on roles :all do
execute :chown, "-R :#{fetch(:group)} #{deploy_to} && chmod -R g+s #{deploy_to}"
end
end
