[For beginners] How to implement the delete function
Posted content
This time I will post about how to implement the delete function.
Activates the destroy action when you press a button like the one below.
Controller action
items_controller.rb
class ItemsController < ApplicationController
#abridgement
def destroy
if @item.destroy
redirect_to root_path
else
render :show
end
end
end
Explanation) When the destroy action is called, the instance variable @item is deleted. If it can be deleted successfully, it will transition to root_path. If it cannot be deleted, it will be handled so that it will transition to the show action.
Ruby description
show.html.haml
.item-show-page__destroy-btn
= link_to "Delete the item", item_path(@item), method: :delete, class: "item-show-page__destroy-link"
Explanation) Specify @item with link_to, and specify delete for the method.
Now you can delete it by clicking the button.
Finally
The delete function this time is very simple, so even beginners may find it easy to get started. Please refer to it!
