Rails - Sep 2010 - Trying to look up comment through an ID, but failing

I am trying to allow users to reply through comments by allowing users
to click a reply link next to the parent comment. It will send in a
parameter to the ''new'' comment view, like so:

  | <%= link_to "Reply", new_comment_path(:in_reply_to =>
comment.id) %>

The form will use the :in_reply_to parameter in order to save that id as
the parent id, like so:

comments_controller#new:
    @comment_parent = Comment.find(params[:in_reply_to])

comments_form view:
  <%= form_for([@comment]) do |f| %>
    <%#= render ''shared/error_messages'', :object =>
f.object %>
    <div class="field">
      <%= f.label :title %><br />
      <%= f.text_field :title %>
    </div>
    <div class="field">
      <%= f.label :content %><br />
      <%= f.text_area :content %>
    </div>
      <%= f.hidden_field :parent_id, :value => @comment_parent.id %>
    <div class="actions">
      <%= f.submit "Post Comment" %>
    </div>
  <% end %>

So, in the create controller, I want to create a new comment based on
the parameters, and then find the parent comment by looking up the
parent_id in Comment.find, but it cannot find any comment with that ID.

comments_controller#create
      @comment = Comment.new(params[:comment])
      @comment.user_id = current_user.id
      @comment.save!
      @comment_parent = Comment.find(params[:parent_id]) # cannot find a
comment with this ID?
      @comment_parent.children << @comment
      if @comment.save
        flash[:success] = "Comment saved."
        @comment_parent.save
        redirect_to @comment
      else
        flash[:error] = "Error in creating comment."
  #      @comments = @commentable.comments.paginate(:page =>
params[:page])
        render ''new''

I get this error: Couldn''t find Comment without an ID, from this line:
      @comment_parent = Comment.find(params[:parent_id])

I also try @comment_parent = Comment.find(@comment.parent_id), but I get
the same error.

Thank you.

Why not just:
   @comment = Comment.new
   @comment.parent_id = params[:in_reply_to] if params[:in_reply_to]
>     </div>

and skip the :value assignment in the view, the value is already there

and you shouldn''t need any of this...

place a hidden field in the  form, add link_to_function and change the value
of the hidden field with javascript.

In the controller if the value of the hidden fill is empty the comment has
no parent, else it does.


example with jquery


$("#the_form [type=hidden]").val("<%=comment.id%>")

this will put the id value of the selected comment in the form parent hidden
field

Nice, is there a way that I can save the particular page from which the 
user is replying to, so I can redirect him there afterwards?

In my show controller for my comments, I have this:
@commentable = find_commentable
where commentable can be article, profile, etc.

Would I do the exact same thing to pass it all throughout the comment 
posting process, or is there a more efficient way to do this?

Hi,
When I try that with a threaded comment, it runs into an error:
Cannot redirect to nil!

I am using a polymorphic association for my articles,profiles and 
comments. My comments controller marks the articles and profiles as 
commentable, but I have to take a different approach when it comes to my 
comments.

oh , i forgot you are doing polymorphic associations sorry,


redirect_to polymorphic_path(@commentable)


remember to catch @commentable with the find_commentable method

you can find it iterating the params hash or user a context_Type in the
route , i like that last one more.

Do you know if there is anyway for my find_commentable method to treat a 
comment the same way as an article?

So, when a user tries to reply to a comment, the URL looks like this:
http://localhost:3000/comments/new?in_reply_to=56

When a user replies to an article (or profile), it looks like this:
http://localhost:3000/articles/304

The find_commentable way only works for the second method URL, since it 
cannot find a commentable in the first one.

Sorry, this is my first Rails application, so my code is very cluttered, 
and I don''t think I thought everything through the first time.

Here''s my comments controller:

and you will have to catch the owner of the first comment. One thing you
should understand is that
you keep trying to treat comments as if they were not associated and as if
they were, let me explain.

comments belong to commentable, and you created this route

articles :has_many :comments


this route is nesting commentes like this

/articles/1/comments


this is to help you get the parent of the comment, the params hash will
catch that id after the articles and create a key called
articles_id, take a look at the find_commentable function

def find_commentable
  params.each do |name, value|
    if name =~ /(.+)_id$/
      return $1.classify.constantize.find(value)
    end
  end
  nilend

For each value in the params hash,( note that the params hash has this
format, :id=>"1", this is , name=>value), it uses a regular
expression to see if the name ends with  _id, hoping that only the
commentable object will end like this i then takes the first part of
the name(  thats what $1 does if there are more (.+) in the regular
expresion you refer to them in order, $2 , $3 etc), in case of article_id it
will take article , then with constantize it becomes Article and a find is
perform passing as an id the value corresponding to
article_id, so it return the instance that has those comments as childs.

now lets say you try to do this without

articles :has_many :comments

you have to provide the parent object somehow , if you access
http://localhost:3000/comments/new?in_reply_to=56
who does that object belongs to really when you access /articles/1/comments,
active record will see that the comments created
that way have no commetable_type and no commetable_id, those are the 2
fields AR uses for the polymorphic associations.

What you are trying yo do is easy, but is not the rigth way , you have to
have comments belong to commentable and to themself
then on the commetable show iterate the comments that have no parent .
inside the iteration iterate for their children.

Is this fine inside of my comment.rb model?

What does this accomplish? I find the comments that have children, but 
what for?

is the comment form in the commentable  show view , for example, comments
are displayed at the bottom of the the article, and is the same with any
commentable, you dont need this


 def new
    @commentable = find_commentable               <===== is no needed here
    @comment = Comment.new                            <====== this is ok
    @comment.parent_id = params[:in_reply_to] if
params[:in_reply_to]             <==== where is params[:in_reply_to] coming
from?
  end

since the user will never go there, that is the new view .


def create
    @commentable = find_commentable               <=== as explained returns
@article or whatever from the /article/1 path
    if @commentable.nil? # Threaded Comments          <==== this will never
happen under normal circumstances
      @comment = Comment.new(params[:comment])       <==== you are creating
orphan comments and will never be able to read them
    else
      @comment = @commentable.comments.build(params[:comment])           <
===== this is ok
    end
    @comment.user_id = current_user.id
<=========== this is ok , from here to the end of create
    if @comment.save
      flash[:success] = "Comment saved."
      redirect_to polymorphic_path(@commentable)
    else
      flash[:error] = "Error in creating comment."
# @comments = @commentable.comments.paginate(:page => params[:page])
      render ''new''
    end
  end


now the destroy action


def destroy
    @commentable = find_commentable                               <== no
need to find the parent you are going to delete it
    if @commentable.comments.find(params[:id]).destroy        <== no ,
change this to    @comment = Comment.find(params[:id])
      flash[:success] = "Comment
deleted."
    else
      flash[:error] = "Comment could not be deleted."
    end
    redirect_to @commentable
  end

 change the above to

def destroy
  @comment = Comment.find(params[:id])
     if @comment.destroy
       flash[:success] = "Comment
deleted."
     else
      flash[:error] = "Comment could not be deleted."
    end
    redirect_to @commentable
  end


the edit

def edit
    @commentable = find_commentable
    @comment = @commentable.comments.find(params[:id])
    @title = "Edit Comment"
# The following code allows editing directly on the article page.
# @comments = @article.comments.paginate(:page => params[:page])
# render ''articles/show''
  end


same as the new , is you are editing at he show of the comentable the user
will never go to the comments edit page.


now the update

def update
    @commentable = find_commentable
    @comment = @commentable.comments.find(params[:id])
    if @comment.update_attributes(params[:comment])
      flash[:success] = "Updated Comment"
      redirect_to @commentable
    else
      flash[:error] = "Comment update failed."
      @comments = @commentable.comments.paginate(:page => params[:page])
      render ''edit''
    end
  end


this one is ok but pay attention to  render ''edit'', if the
user will never
go there.

and last

 def correct_user
      @commentable = find_commentable
      redirect_to(@commentable) unless current_user.admin?
    end


try using an authorization gem instead

by parent i mean commets where the parent_id is nil, not comments wherre
comentable is nil,

Comment.rb is ok but you still need to self refer, to create the threads.


ill tell you what. i will make this tomorrow and send it to you ill try to
commented well, do you want it in rails 2 or 3?

Yes, right now. The article show page renders a partial of a comment 
form.

My article''s show page renders a partial for comments:
<%= render ''shared/comments'' %>

Here is what the comments looks like:
<% unless @comments.nil? || @comments.empty? %>
    <%= render :partial => ''shared/comment'', :collection
=> @comments %>
    <%#= will_paginate @comments %>
<% end %>

And each comment has this link which is where the params[:in_reply_to] 
comes from:
  | <%= link_to "Reply", new_comment_path(:in_reply_to =>
comment.id) %>

Sorry about the edit and destroy methods. You can ignore them for now. I 
was going to change them after I learned how the create and new methods 
worked. Don''t worry about the edit and destroy methods.


I am using Rails 3.

hum ? i didnt see any more replays from you so i stopped adding features to
it. I was going to add the ajax and the rest of the comment right away , it
was just last night that i thought maybe it was because you where replaying
from your job and that during the weekend you could not reply that i havent
heard anything from you. If you are still interest ill will finish right
away and add the ajax and the rest of the comment.
