ruby on rails - I can't cope with custom action in controller -

in tasks controller have action:

def destroy_all current_user.tasks.destroy redirect_to root_path end

my db schema looks below:

create_table "tasks", force: true |t| t.string "content" t.boolean "done" t.datetime "created_at" t.datetime "updated_at" t.string "users_id" end

and have relation: tasks belongs_to user , user has_many tasks. action destory_all want destroy current user's tasks.

but when click:

<%= link_to "delete all", { controller: 'tasks', action: 'destroy_all'}, method: 'delete' %>

nothing happen. user still have tasks.

log server console:

started delete "/tasks/destroy_all" 127.0.0.1 @ 2014-10-04 23:29:27 +0200 processing taskscontroller#destroy_all html parameters: {"authenticity_token"=>"fvpdi6bcznxlfhjcdi4pjhmum3cjv6tn1ny/uluo4yq="} user load (0.2ms) select "users".* "users" "users"."id" = 2 order "users"."id" asc limit 1 redirected http://localhost:3000/ completed 302 found in 31ms (activerecord: 0.2ms) started "/" 127.0.0.1 @ 2014-10-04 23:29:27 +0200 processing pagescontroller#home html user load (0.2ms) select "users".* "users" "users"."id" = 2 order "users"."id" asc limit 1 task load (0.1ms) select "tasks".* "tasks" "tasks"."done" = 'f' , "tasks"."user_id" = 2 rendered tasks/index.html.erb within layouts/application (2.4ms) rendered layouts/_userbar.html.erb (0.2ms) rendered layouts/_menu.html.erb (0.1ms) completed 200 ok in 46ms (views: 44.3ms | activerecord: 0.3ms)

and routes.rb file

resources :tasks collection delete :destroy_all end end

edit: updated log , link_to method , added routes.rb file.

first, task table needs field "user_id", not "users_id". prepare problem right away.

however, you're missing powerfulness of has_many! this:

current_user.tasks.destroy_all

calling "current_user.tasks" gets list of user's task you, , can phone call "destroy" on them did above. cleaner , easier read.

i hope helps!
