Я новичок в Ruby On Rails и в настоящее время создаю стандартные операции CRUD для панели администратора, которую я создаю вручную в приложении (без использования гемов администратора).
Тем не менее, когда я вызываю ссылку удаления на моей странице show.html.erb, ничего не происходит (без экрана ошибок или каких-либо других отзывов в браузере).Javascript полностью включен, и я считаю, что у меня установлены правильные гемы.
Может кто-нибудь сообщить мне, как лучше всего это исправить?Я свяжу все соответствующие файлы ниже:
app / views / admin / posts / show.html.erb
<h1><%= @post.title %></h1>
<p><%= @post.body %></p><br>
<%= link_to "delete", [:admin, @post], method: :delete %>
controllers / admin / posts_controller.rb
class Admin::PostsController < Admin::ApplicationController
def index
@post = Post.all
end
def show
@post = Post.friendly.find(params[:id])
end
def new
@post = Post.new
end
def create
post_params = params.require(:post).permit(:title, :body, :slug)
@post = Post.new(post_params)
@post.save
redirect_to [:admin, @post]
end
def destroy
@post = Post.friendly.find(params[:id])
@post.destroy
end
end
