Heroku Rails Migration error

NoMethodError: undefined method reset_sent_at hartle tutorial
ruby-on-rails,railstutorial.org,nomethoderror
Another migration is already named add_reset_to_users: You had already created the migration previously, as you noted, but this migration did not include the addition of the reset_sent_at column.

AFIK, cloud9 IDE does not have a ruby debugger. According to their documentation, the debugger only support javascript/node.js apps: Note: Currently, only Javascript/Node.js applications can make use of the debugger. Hopefully, I'm wrong, and they've implemented it for ruby. ...
Rails 4 server fails, Ruby 2.0 segmentation fault, Abort trap 6

Your Rails -v and Ruby -v are correct for this tutorial. I can also see from the input that your gemfile has gem 'sqlite3', '1.3.8' in it. 1: Have you bundled? When was the last time you ran bundle update or bundle install? How did you go about uninstalling sqlite3?...
Rails: Minitest tests fail when they should pass
ruby-on-rails,testing,tdd,railstutorial.org,minitest
So, I kept following the tutorial, and in the next chapter (Chapter 4), at some point, we create the full_title helper and remove the <% provide(:title, "Home") %> from the views. I am not sure how, but this solved the problem and made the tests to pass: 11:49:36 - INFO...
ArgumentError in Rails::MailersController#preview (wrong number of arguments (1 for 0))
ruby-on-rails-4,actionmailer,railstutorial.org
You are calling UserMailer.password_reset(user) and passing in the user but your password_reset method does not take an argument. So either you will need to change your password_reset to take a user (and do something with it) def password_reset(user) #do something with the user, such as send to their email address...

ruby-on-rails-4,railstutorial.org
I did run bundle install while I was trying to install rcov (Rubymine was complaining about its lack). The installation failed as rcov is not available for my version of rails. That's fine. The really bizarre thing is that afterwards I re-ran the tests and everything worked. There was no...

Rails Tutorial Chapter 6 create user error “SELECT 1 AS one FROM ”users“ WHERE LOWER(”users“.”email“) = LOWER('[email protected]') LIMIT 1”
ruby-on-rails,ruby,railstutorial.org
Based on what you've provided, the error you're getting is because there's already a user in your DB with the email address and you have a uniqueness validation on the :email field so you can't save another record with the same email. That's my best guess, if it's wrong, do...
NoMethodError: undefined method `email' for nil:NilClass
ruby-on-rails-4,integration-testing,railstutorial.org,minitest
This is because @user was not initialized in your setup method. You initialize @admin and @non_admin, but not @user.

ruby-on-rails,railstutorial.org
Try like that:- <p>Project: <%= @work.project.present? ? @work.project.name : "" %></p> Here @work doesnot have any project, so the project of that @work is nil. So due to @work.project.name, it is throwing that error. The relation should be like that:- class Project < ActiveRecord::Base has_many :works end class Work <...
Can't open Hartl's sample_app on local server

Understanding errors First of all, it's important that you learn to read & understand error messages properly: wrong number of arguments (2 for 1) for `asset-path` (in /app/assets/stylesheets/bootstrap_and_overrides.css.scss:1) This basically says, there are 2 arguments for the asset-path helper, but only 1 is expected.

Parameter passing and assert_difference
ruby-on-rails,ruby,railstutorial.org
Blocks aren't really parameters - what shows up in the method signature is that this method captures the block passed to it in a proc, but that is really an implementation detail that is leaked to the outside world. For example if you define a method like this def foo(*args)...

This: <%= link_to "Settings", 'edit_user_path(current_user)' %> should become this: <%= link_to "Settings", edit_user_path(current_user) %> Your logs shows that app looks for /edit_user_path(current_user) because you send it as a string and normally you don't have this path.

NoMethodError in SessionsController#destroy undefined method `forget' for nil:NilClass
ruby-on-rails,ruby,railstutorial.org
Your log_out method is deleting the session before forgetting the user.

Post vs Post_via_redirect in Rails 4 not behaving in expected way
ruby-on-rails,ruby-on-rails-4,railstutorial.org
I'm posting here for completeness, but I was able to find my own answer. Here it is: Do the redirection options get lost whenever we call a via_redirect, and thus testing assert_redirected_to @user fails? Yes! Because of the way request_via_redirect works: # File actionpack/lib/action_dispatch/testing/integration.rb, line 92 def request_via_redirect(http_method, path, parameters...

How does the RailsTutorial SessionsHelper get referenced by UsersContoller?
ruby-on-rails,railstutorial.org
You need to include the sessions helper for it to be available in the controller/view layers.

Rails Tutorial: NameError in sessions_helper
