I've been having problems making threaded comments for the last few
days. Mainly with creating children and displaying the children.
Currently, I have comments shown at the bottom of my articles show view.
The top level comments work, but I do not really know how to implement a
way for users to "reply" to the top level comments and take them to a
form (the comment 'new' view) to create a new comment. I want the
controller to determine if the user is creating the new comment in an
article or in a comment and create the new comment as a child if its
parent is a comment. I've been facing multiple problems, maybe the
recursion messes up and I get an infinite loop.
Here is the articles show controller:
def show
@article = Article.find(params[:id])
@commentable = Article.find(params[:id])
@comments = @commentable.comments
# @comments = @commentable.comments.paginate(:page => params[:page])
@comment = Comment.new
@title = @article.title
end
Here is my comments controller:
def show
@commentable = find_commentable
@comment = @commentable.comments.find(params[:id])
# @comments = @commentable.comments.paginate(:page => params[:page])
end
def new
@commentable = find_commentable
@comment = Comment.new
end
def create
@commentable = find_commentable
if @comment.commentable_type == "Comment"
@comment = @commentable.children.create(param[:comment])
else
@comment = @commentable.comments.build(params[:comment])
end
@comment.user_id = current_user.id
if @comment.save
flash[:success] = "Comment saved."
redirect_to @commentable
else
flash[:error] = "Error in creating comment."
# @comments = @commentable.comments.paginate(:page =>
params[:page])
render 'new'
end
end
Here is the comment creation form:
<%= form_for([...@commentable, @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>
<div class="actions">
<%= f.submit "Post Comment" %>
</div>
<% end %>
Here is the loop that goes through all of the existing comments:
<% unless @comments.nil? || @comments.empty? %>
<%= render :partial => 'comments/comment', :collection => @comments
%>
<%#= will_paginate @comments %>
<% end %>
Here is what each individual comment looks like:
<div id="comment <%= comment.id %>">
<%= comment.title %>
| <%= link_to "Permalink", polymorphic_path([...@commentable, comment]),
:action => :show %>
| <%= link_to "Reply", polymorphic_path([...@commentable, @comment]),
:action => :new %>
| <%= link_to "Edit Comment", polymorphic_path([...@commentable,
comment]), :action => :edit %>
| <%= link_to 'Delete Comment', [...@commentable, comment]], :confirm =>
"Are you sure?", :method => :delete %><br />
<%= comment.content %><br />
<%= comment.user.name %><br /><br />
<%= render :partial => 'comments/comment', :collection =>
@comment.children %>
</div>
When I click reply, I get taken to:
http://localhost:3000/articles/299/comments and not
http://localhost:3000/articles/299/comments/new. I went into rails
console and gave one of my comments a comment child, and the recursive
nature of the threaded comments gave me recursion that crashed my site.
