Link_to relation problems in rails - ruby-on-rails

Question

building my first blog, head is spinning.
I am trying to show comments in my dashboard view. I am able to pull in the comments and the ID but what I would really like to do is also put the title of the post the comment lives and link to it. From my very amateur understanding I think I am not making the connection from comments to post.
Here is what I got...
Post model has_many :comments
Comments model belongs_to :posts
routes
resources: posts do
resources: comments
end
Dashboard Controller:
class DashboardController < ApplicationController
before_filter :authorize, only: [:index]
def index
#posts = Post.all
#comments = Comment.all
end
end
Comments Controller:
class CommentsController < ApplicationController
before_filter :authorize, only: [:destroy, :show]
def create
#post = Post.find(params[:post_id])
#comment =
#post.comments.create(comments_params)
redirect_to post_path(#post)
end
def destroy
#post = Post.find(params[:post_id])
#comment = #post.comments.find(params[:id])
#comment.destroy
redirect_to post_path(#post)
end
private
def comments_params
params.require(:comment).permit(:commenter, :body)
end
end
Posts Controller:
class PostsController < ApplicationController
before_filter :authorize, only: [:edit, :update, :destroy, :create, :new]
def index
#posts = Post.where(:state => "published").order("created_at DESC")
end
def new
#post = Post.new
end
def show
#post = Post.find(params[:id])
redirect_to_good_slug(#post) and return if bad_slug?(#post)
end
def create
#post = Post.new(post_params)
if #post.save
redirect_to dashboard_path
else
render 'new'
end
end
def edit
#post = Post.find(params[:id])
end
def update
#post = Post.find(params[:id])
if #post.update(params[:post].permit(post_params))
redirect_to dashboard_path
else
render 'edit'
end
end
def destroy
#post = Post.find(params[:id])
#post.destroy
redirect_to dashboard_path
end
private
def post_params
params.require(:post).permit(:title, :text, :author, :short, :photo, :state)
end
end
Dashboard View:
</div>
<div class="fluid dash">
<div class="gridContainer clearfix">
<div class="fluid dash_post_list">
<h3>Manage Posts</h3>
<% #posts.each do |post| %>
<div class="fluid list-items">
<div class="fluid list_each">
| <%= post.id %> | <%= link_to post.title, post %>, <%= post.created_at.strftime('%b, %d') %> - <%= post.state %>
</div>
<div class="fluid crud">
<i class="fa fa-pencil-square-o"></i><%= link_to 'Edit', edit_post_path(post) %>
<i class="fa fa-times-circle"></i><%= link_to 'Delete', post_path(post),
method: :delete, data: { confirm: 'Are you sure?' } %>
</div>
</div>
<% end %>
</div>
<div class="fluid dash_right">
<div class="fluid create_new">
<h3>Create New</h3>
<%= link_to 'New Post', new_post_path %>
</div>
<div class="fluid alerts">
<h3>Alerts!</h3>
<% #comments.each do |comment| %>
<%= comment.post_id %>
<% end %>
</div>
</div>
</div>
</div>
DB Schema
create_table "comments", force: true do |t|
t.string "commenter"
t.text "body"
t.integer "post_id"
t.datetime "created_at"
t.datetime "updated_at"
t.boolean "flag", default: false
end
create_table "posts", force: true do |t|
t.string "title"
t.text "text"
t.datetime "created_at"
t.datetime "updated_at"
t.text "short"
t.text "author"
t.string "photo_file_name"
t.string "photo_content_type"
t.integer "photo_file_size"
t.datetime "photo_updated_at"
t.string "state"
end
The end goal is, when a user makes a new comment, add it to alerts in the dashboard where I can then take a link from the dashboard to the post and then approve or delete it.
Thanks you for any help you can give me.

Answer 1

So from you question, My understanding is that you cannot create a link to the post?
Forgetting ajax for now. This is how you like it to the post show page.
Dashboard:
-#comments.each do |comment|
.comment
=link_to comment.body, comment.post
and in the post show page
-#comment.each do |comment|
.comment
=link_to 'Approve', approve_comment_path(comment)
=link_to 'Delete', comment_path(comment), method: :delete
You will need a custom action to set it to approve or you can reuse the update action.
