ruby on rails 5 - NoMethodError in Controller#show - Nested model -

it might newbie question can't head around it. rails telling me method not defined if can access in console. i'm missing obviously...

here routes.rb file:

rails.application.routes.draw    root   'static_pages#home'     resources :users     resources :bodies   end end 

here user model

class user < applicationrecord   has_many :bodies, dependent: :destroy end   

here body model

class body < applicationrecord   belongs_to :user end 

here bodies controller

class bodiescontroller < applicationcontroller    def new       @user = user.find(params[:user_id])       @body = @user.bodies.new   end    def create     @body = current_user.bodies.build(body_params)       if @body.save         redirect_to user_body_path(@body)       else         render 'new'       end   end    def show     @user = user.find(params[:user_id])     @body = @user.bodies(params[:id])   end    def index     @bodies = body.all   end private    def body_params     params.require(:body).permit(:weight, :sex, :age, :fat)   end  end 

the create action working fine. i'm struggling show action work although right parameters passed along :

showing /users/rodolphegeant/code/ffl/app/views/bodies/show.html.erb line #9 raised:  undefined method `sex' #<body::activerecord_associations_collectionproxy:0x007f820f65da90> did mean?  send extracted source (around line #9): 7 8 9 10 11 12  hello body  <%= @body.sex %> | <%= @body.age %> | <%= @body.weight %> | <%= @body.fat %>     rails.root: /users/rodolphegeant/code/ffl  application trace | framework trace | full trace app/views/bodies/show.html.erb:9:in `_app_views_bodies_show_html_erb___2597620731841156962_70098290142700' request  parameters:  {"user_id"=>"1", "id"=>"3"} 

when go console can run @body.sex or @body.age or other method corresponds attributes i'm looking for....

thanks lot in advance helping me resolve issue.

you should run find query on records return association user model.

def show   @user = user.find(params[:user_id])   @body = @user.bodies.find(params[:id]) end
