Issue in setting up an existing Ruby On Rails Project in local setup

Question

I am setting up an existing 'Ruby On Rails' project to my local system (Having Mac OS X 10.8). I have installed all the required gems but, when i am trying to Load database schema for the project it shows error in terminal 'Could not find table rv_classes' i am a very beginner in Ruby On Rails.
I have no clues now how to fix it. thanx in advance.

The response from terminal is as following

Cynosures-Mac-mini:sunridgerv cynosure$ bundle exec rake db:schema:load
rake aborted!

(See full trace by running task with --trace)

*As it says a duplicate column "ID" in 'blog_posts' table ... here is the schema for this table in schema.rb*

 create_table "blog_posts", :force => true do |t|
    t.text     "post_title"
    t.datetime "post_date"
    t.text     "post_content"
    t.string   "post_image"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "post_name"
    t.integer  "ID"
  end

Answer 1

Comment out this line:

ActiveAdmin.routes(self)

then run your bundle exec rake db:schema:load and uncomment it back.

About your second error, I guess you should remove t.integer "ID" line from blog_posts in your schema.
