ruby on rails - how to associate checkbox used in view to update a field in a RoR table? -

i have created new field called "reviewed" in 1 of tables called "posts". everytime checkmarks prior post, want reviewed approval prior display.

the "reviewed" field in table defaulted true. here's schema.db

create_table "posts", :force => true |t|     t.text      "content"     t.integer   "user_id"     t.timestamp "created_at",                        :null => false     t.timestamp "updated_at",                        :null => false     t.boolean   "reviewed",        :default => true 

here's code in view i'm using checkmark

<%= label_tag(:post_reviewed, "review post") %> <%= check_box_tag(:post_reviewed) %> 

i want every time checkbox checked, reviewed field set false post not displayed until review , update true. how can this?

you have in view:

<%= form_for :post |f| %> .. <% end %> 

so, try add it:

<%= f.check_box :reviewed %> 

that should automatically associate desired object.

let me know if works you.
