Syntax Error with rails unexpected ')'

Question

Hi there I want to add a destroy action in post#show view I think I have creates the environment but when I place this code with a condition I have a message error.

<% if @user.comment == current_user %> 
  <% link_to @post_comment_path(post_id: @post.id, id: comment.id), method:    :delete, data: { confirm: "Are you sure?" } do %> 
  <i class="fa fa-trash"></i> 
<% end %>
 <% end %>

I created a partial in post show#view which names _comments.html.erb

here it is

<p class="text-center">Poster un commentaire</p>
      <%= simple_form_for [post, post.comments.new] do |f| %>
        <%= f.error_notification %>
        <%= f.input :content, label: "Commentaire"%>
        <%= f.submit "Envoyer", class: "btn btn-primary" %>
      <% end %>

and it render like that <%= render 'comments' %>

and above the partial (in post show#view) I do an iteration like that

<ul class="list-unstyled">
    <% @post.comments.each do |comment| %>
   <li>
      <p><% comment.content %></p>
   <% end %>
   </li>
</ul>

But nothing appears when I create a new message, I don't userstand why.

I give your more code details

post.rb

has_many :comments, dependent: :destroy

comment.rb

belongs_to :user
belongs_to :post

The route is:

resources :posts do
  resources :categories
  resources :comments
end

Comments controller is

class CommentsController < ApplicationController

before_action :set_post

def create
  @comment = @post.comments.build(comment_params)
  @comment.user_id = current_user.id

  if @comment.save
    flash[:success] = "You commented the hell out of that post!"
    redirect_to :back
  else
    flash[:alert] = "There is a problem with your comment"
    render root_path
  end
end

def destroy
  @comment = @post.comments.find(params[:id])

  @comment.destroy
  flash[:success] = "Comment deleted :("
  redirect_to root_path
end

private

def set_post
  @post = Post.find(params[:post_id])
end

def comment_params
  params.require(:comment).permit(:content, :post_id, :user_id)
end
end

Thank you so much for your help.

您的link_to erb代码需要等号才能实际显示

<%= link_to post_comment_path(post_id: @post.id, id: comment.id), method: :delete, data: { confirm: "Are you sure?" } do
