I'm trying to go from a newly installed version of rails. To creating a project and migrating the database based off of the model that I scaffolded using rails. And I'm running into a Don't know how to build task 'db::migrate' error.
Commands I ran..
Removing all gems:
for i in 'gem list --no-versions'; do gem uninstall -aIx $i; done
Installing rails and creating new project
sudo gem install rails
rails new test-api
rails generate controller user index
rails generate model user name:string
So that is my setup..
Then I did the method to migrate my database:
rake db::migrate
And here was my output:
rake db::migrate
rake aborted!

I found a solution. Had I just refreshed my page on my server I would have found this:
Which gave me the answer to just run this command:
bin/rake db:migrate RAILS_ENV=development

I've recently joined a team on a Ruby-on-Rails application, and I try to audit the tests. There were no tests, so I decided to implement them in the app.
After seeing around what was there, I have seen there were no command to run the tests available. I ran the following command:
rails --tasks
In the output, there is no command such as rails test, rails test:system. Surprisingly, I can run the command rails test with success. But the command rails test:system --trace fails with following output:
rails aborted!

I have tried running the command in a freshly created app, and I can see the available commands rails test and rails test:system.
rails --tasks
Any idea why the command rails test:system fails? Thanks.
Ruby version: 2.3.3
Rails version: 5.2.0
EDIT:
I'm using MiniTest
To run all specs in a single go:
rspec
To execute a specific test file:
rspec <path to the file> # rspec spec/controllers/mytest_spec.rb
Use --format documentation for a formatted output.
Prepend bundle exec if rspec throws a dependency error.
My environment:
Ruby 2.4.1
Rails 5.1.4
I am trying to use the attach gem, written by the person who also wrote this article https://atech.blog/atech/file-attachments-in-rails-tutorial.
When I run the bundle install it installs attach gem, version 1.0.2
Then when I try to run the rake command I get an error saying it does not know how to build the task.
rake attach:install:migrations --trace
rake aborted!

There are no rake tasks defined in this repo.
After you run bundle install, you can get a list of rake tasks by running rake -P (rake -T shows tasks with descriptions). You'll see that attach:install:migrations is not there.
Why not try using paperclip?
I come from a computer science and programming background, and I am familiar with a *nix CLI.
I am new to ruby on rails, and I am doing an online bootcamp. One of my lessons has me creating a new rails application. It starts out with the following commands to create a new rails application and create the database:
$ rails new bloccit -T
$ cd bloccit
$ rake db:create
When I run the rake command, the process just hangs. I let it run for 30 minutes, and it just sat there. When I do a hard interrupt, I get the following stack trace:

I understand the stack trace: on line 99 in the run.rb file, the method gets is getting stuck. I just don't know anything about spring.
I am running Ruby 2.2.1p85, Rails 4.2.1, and sqlite3 1.3.10.
Stop spring by using command
bin/spring stop
and then run rake command again. It would fix this issue.
I am trying to install redmine 2.3.x on my Debian vServer. I already managed to build ruby from source and installed gems, rails and the apache passenger module. It should work until that point. I used the turotial at domainfactory: http://www.df.eu/de/service/df-faq/cloudserver/anleitungen/ruby-on-rails-installieren-debian-ubuntu/ .
After that I downloaded and extracted the redmine application as described here: http://www.redmine.org/projects/redmine/wiki/RedmineInstall#Installation-procedure. I created a mysql account and database, made a copy of the config/database.yml.example -> config/database.yml and filled in the correct values.
After that I installed bundler with
gem install bundler
And did go on with preparing the environment:
bundle install --without development test
All these commands did succeed.
After that I wanted to generate the secret token with the fallowing command:
rake generate_secret_token
The execution was interrupted with the fallowing message:
# rake generate_secret_token --trace
rake aborted!

I was trying to resolve this by checking versions and installed gems.
Ruby: ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-linux]
Rails: Rails 3.2.13
Gems: 1.8.25
Redmine: 2.3.3
I verified with gem list --local that the gem "mysql2" is installed.
gem "mysql": mysql2 (0.3.13)
As the problem seems to rely on this, I tried reinstalling the package, but this did not help.
What did I wrong here?
Thanks in advance,
Sebastian Büttner
I found this error happens if you don't have the following package installed in your system (at least on Debian 9). So run command:
apt-get install default-libmysqlclient-dev
try bundle exec rake generate_secret_token
(if #1 does not help) Check if mysql2 is presented in output list for bundle list (it is different with gem list!). Be careful that redmine install DB adapter according to your settings in database.yml (but I think you install it correctly)
Please, check if you have necessary VC runtime installed. Please, check the VC runtime dll version, your mysql vendor dll is dependent upon.
So I've wanted to install RVM for a while on OSX. I finally got it working after figuring out I had to download the latest XCode. I installed ruby 1.9.2 and used these commands to create a new gemset in rvm:
rvm gemset create rails235
rvm 1.9.2#rails235
gem install rails -v 2.3.5
Then I went into one of my old apps that used rails 2.3.5 and tried to run some rakes and any rake I run I seem to get this error:
rake aborted!
no such file to load -- initializer
Also, semi related, right now I'm trying to get rdoc setup. I've never used before and I'm typing in "rake doc::app" and I'm getting that same error.
The full rake with --trace is this:
$ rake doc::app
rake/rdoctask is deprecated. Use rdoc/task instead (in RDoc 2.4.2+)
rake aborted!

Your rake doc::app error is most probably due to the fact that rake tasks only use a single colon (":") to separate namespaces and task names. Try running rake doc:app instead.
