ruby on rails - CRUD action of one controller in another -

is bad practice create 1 of crud action of 1 controller in another? example have 2 models user,post , following controller:

 class userscontroller < applicationcontroller       def show            @user = user.find(params[:id])       end        def update_post #update action of postscontroller            post.find(params[:post_id]).uppdate_attributes(params[:post])       end        def create_post #create action of postscontroller            @user = user.find(params[:id])            @user.posts.create(params[:post])       end  end 

can/should or there better way ? reason why actions not in own controller want manipulate posts @ users page.

it bad practice , impractical if have association already. can use user form , fields_for create/update `posts.

you need instantiate post build, add user model accepts_nested_attributes_for , use fields_for in view , user crud save/update posts

#user controller class userscontroller < applicationcontroller       def show            @user = user.find(params[:id])            @user.posts.build       end  end   #user model accepts_nested_attributes_for :posts   #user/show view <%= form_for @user |f| %>     <%= f.fields_for :posts |post| %>       <%= post.text_field :post %>     <% end %> <% end %>
