Undefined Method Model Path, Form_for not saving, Posted Correctly, Rails Framework -

sorry new rails

right trying build small application https://pinboard.in, trying summer internship them.

here bookmark model

class bookmark < activerecord::base   attr_accessible :url, :title, :description, :counter    belongs_to :user     #validates url has https:// or http://   validates :url, :format => { :with => /(^$)|(^(http|https):\/\/[a-z0-9]+([\-\.]{1}[a-z0-  9]+)*\.[a-z]{2,5}(([0-9]{1,5})?\/.*)?$)/ix,   :message => "invalid url" } end 

here bookmark controller

class bookmarkscontroller < applicationcontroller     def add_bookmark         @bookmark = bookmark.new           respond_to |format|             format.html          end      end       def draw_recent         @bookmarks = bookmark.all     end  end 

here form

<%= form_for :bookmark |f| %>     url: <%= f.text_field :url %><br/>     title: <%= f.text_field :title %><br/>     description: <%= f.text_field :description %><br/>     <%= f.submit "submit" %> <% end %> 

everything rendered correctly , when put in information , submit add

here output

i have 2 thoughts in head, form posting correctly somehow not saving db, need save method in controller?

when try @bookmark instead of :bookmark app throws me error saying wrong bookmarks.path

undefined method `bookmarks_path 

i understand former working instance @bookmark in controller , latter wrapping around model....

can enlighten me? feel trivial guys... :)

should form_for @bookmark |f|. getting undefined method error because have not defined routes in config/routes.rb, add there:

resources :bookmarks 

that add restful resources following crud convention, should change name of controller methods work out-of-the-box. need @ least 3 methods doing right now:

in app/controllers/bookmarks_controller.rb:

first 1 render form @ /bookmarks/new

def new   @bookmark = bookmark.new end 

second 1 process form submission (no action needed apart following naming convention)

def create   @bookmark = bookmark.new(params[:bookmark])   @bookmark.save end 

third 1 show bookmarks in current 'draw_recent'

def index   @bookmark = bookmark.all end 

afterwards can go on validating data, etc basic flow should that.

it better start conventions go later on change method standard names when have more confidence.
