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.

Delayed Job Delayed::PerformableMethod undefined method "delayed_task" for #<Class:0x0000000b4dcd20>

I am using delayed jobs and I think I have a problem with serialization. We are using ruby 2.2.2.
In my model I have a callback that fires on save and creates a delayed job for my model. like this:
after_create :update_queue
def update_queue
self.class.delay(run_at: 1.minutes.from_now, delayed_reference_id: self.id, delayed_reference_type: "Payment", queue: "qbo_payments").delayed_task(self.id)
end
def self.delayed_task
# Do some stuff
end
However I am getting the error:
undefined method `delayed_task' for #<Class:0x0000000f93f9b8>

What I have tried
After a bit of google research I found 2 fixes. The first and more widely accepted fix is to add:
require 'yaml'
YAML::ENGINE.yamler = 'syck'
#https://github.com/collectiveidea/delayed_job/issues/199
However, syck is no longer supported for ruby 2.2.2
The second solution, which only seemed to exacerbate the problem, was to add "bundle exec" to my delayed_job startup script like this:
run "cd #{current_path}; bundle exec script/delayed_job start #{rails_env}"
This will work !
after_create :update_queue
def update_queue
self.delay(run_at: 1.minutes.from_now, delayed_reference_id: self.id, delayed_reference_type: "Payment", queue: "qbo_payments").delayed_task()
end
def delayed_task
self.class.delayed_task(self.id)
end
def self.delayed_task
# Do some stuff
end

Test suite before upgrade to rails 4.2 from rails 3.2

I recently tried to updated my Rails app from Rails 3.2 to Rails 4.2. Before the upgrade all my test suite runs perfectly, but after the update I'm getting something strange. every time i tried to run a test the same error happens

:(
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)
at line 636 of the file fixture.rb from activerecord library

Rake and Ruby on Rails

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:

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

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.
