Hi all,
I recently started back up with Rails and things are going well up until
now.
I''ve set up acts_as_commentable in my Post model and it''s
working great.
Problem is users are able to create a "blank" comment. I''ve
added the
following validations in the comment.rb file generated by
acts_as_commentable to limit the comment length:
[code]
validates_length_of :comment, :minimum => 3, :too_short => "must be
at
least {{count}} words.", :tokenizer => lambda {|str| str.scan(/\w+/) }
validates_length_of :comment, :maximum => 200, :too_long => "must be
shorter than {{count}} words. Make sure there are no links or
elements.", :tokenizer => lambda {|str| str.scan(/\w+/) }
[/code]
The show view form for the comment is the following:
[code]
<%- form_for [@post, @comment] do |f|-%>
<%= f.error_messages %>
<%= f.text_area :comment, :rows => 3 -%>
<p><%= f.submit -%></p>
<%- end -%>
[/code]
However I am getting the following error only when validation fails (if
a normal length comment is created the site works):
[code]
Template is missing
Missing template comments/create with {:handlers=>[:erb, :rjs, :builder,
:rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths
"/...",
"/.../.rvm/gems/ruby-1.9.2-head/gems/devise-1.2.1/app/views"
[/code]
Any idea how I can render just a regular validation error? Thanks in
advance!

What happens in there if the validation fails (ie save will return zero). What view does it attempt to show in that case?

I had: def create @post = Post.find(params[:post_id]) @comment = @post.comments.new(params[:comment]) @comment.user_id = current_user.id if @comment.save redirect_to @post end end What I needed was to add an else statement to @comment.save like so: def create @post = Post.find(params[:post_id]) @comment = @post.comments.new(params[:comment]) @comment.user_id = current_user.id if @comment.save redirect_to @post else redirect_to @post end end Now the problem I''m having showing the validation errors on my post show form (code in my original message). Any tips on displaying that? Thanks! -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
