Do you mean a new table, rather than a new database?

Can you post the file db/schema.rb please.

By the way, it is generally better to copy/paste the error from the terminal window rather than post the html.  It should also be in development.log.

here is the  schema


ActiveRecord::Schema.define(version: 20141016020227) do

  create_table "articles", force: true do |t|
    t.string   "title"
    t.text     "text"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "time"
    t.string   "age"
    t.string   "el"
    t.string   "experience"
  end

  create_table "shops", force: true do |t|
    t.string   "title"
    t.text     "text"
    t.datetime "created_at"
    t.datetime "updated_at"
  end

end

and yeah i meant new table.

I think you need to put the url parameter in the form like this:

 shopping_path(@shop)

I think you can also omit the URL parameter entirely and the form_for will know which path to use automatically because you have supplied the object that the form is bound to. (I am 95% sure I am correct so leave 5% room for error in this information)
