Rake and Ruby on Rails - ruby

I am a new user on RoR. I would really appreciate it if you can give me some guidance here. Below is the issue that I have encountered. Thank you in advance!
I am trying to do the following command
C:\Users\01TAN\rails_projects\demo_app>bundle exec rake db:migrate
However, I received the following error
rake aborted!
An error has occurred, this and all later migrations canceled:
undefined method `vantan08' for #<ActiveRecord::ConnectionAdapters::TableDefinit
ion:0x217c128>
I used the trace command and below is the report:
C:\Users\01TAN\rails_projects\demo_app>rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment

Tasks: TOP => db:migrate

My guess is that the migration you were writing mixed up the name of a column with the type of a column. Migrations should look something like this in Rails 3.2.1:
class CreatePeople < ActiveRecord::Migration
def change
create_table :people do |t|
t.string :name
t.string :email
t.timestamps
end
end
end

Error emerging at Object.create... stage, what is wrong?
Update: In a comment it was pointed out that the actual code was not containing "Object", this answer is thus based on the wrong example.
Object is a bad name to use for an (unscoped) Model class, as it is already defined by Ruby.
The Object you are calling create on is probably not the Object class you defined in your model sources.
I assume you run rails. Remove the Object.create lines from your migration. Run it, it should work fine. Then, call rails console, where you end up in a live session. Here you can play around with your code, e.g. call Object.create, Object.where{id: 1} etc. I assume that you will get the same errors.
So, as a solution, rename your Object into something else, like Class and look if it works.
Okay, that was a joke, of course Class is also a really bad name for a model class :) . Try to find something more meaningful.
The problem was solved by set up pg gem, which pull bundle of another gems and packs (particularly postgresql-server-dev-all). After installing it, the command rake db:migrate works fine and completely.

:(
I did a progressive updatefrom rails 3.2 to 4.02, then from 4.02 to 4.1, all worked smoothly, then at rails 4.2 i got the same error
i posted the issue at github in rails repositories and they answer me that it's a bug and will be released at version 4.2.1
for the moment you can correct this doing this.
row[key] = value.gsub("$LABEL", label.to_s) if value.is_a?(String)

Resque workers fail upon startup

Resque workers won't start locally in my rails application. I enter the following command to startup a worker.

And I run into the following error. I had this working before, not sure what is causing the error to appear now.

Tasks: TOP => resque:work => resque:preload
As well below is my lib/tasks/resque.rake file.
require 'resque/tasks'
require 'resque_scheduler/tasks'
task "resque:setup" => :environment do
ENV['QUEUE'] = '*'
end
desc "Alias for resque:work (To run workers on Heroku)"
task "jobs:work" => "resque:work"
task "resque:scheduler_setup" => :environment
I've added the resque.rake file to the load path by adding the following in the config/application.rb
config.autoload_paths += %W(#{config.root}/lib/tasks/)
Thanks for your help.
The output statement is a little misleading.
No such file to load -- exception
Turns out I had require exception in one of my models, and it was complaining because it couldn't find the file exception.

Tasks: TOP => assets:precompile
Not your issue, but if a Google search brings someone else here (as it did me) make sure you're specifying what RAILS_ENV you're in:
rake assets:precompile RAILS_ENV=development
I was running a precompile test in development and kept getting this error until I remembered to put the environment.
You've got a wrong password/username combination for your MySQL database. There are some gems that "need" database access for asset precompilation, to turn this off, check this question for Devise.
