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

12345

Shopping#new

<%= form_for @shop, url: shopping_path do |f| %>

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)
