Question

I’ve got a really simple rails question here but I can’t seem to find the answer anywhere. I guess some of the problems stem from me following a tutorial for Rails 1.2 with Rails 2.1. Anyway..

I’m writing a blog system and I’m implementing the comments bit. I have comments displaying fine once I’ve created them using script/console, but getting the comment form itself working is the hard bit.

In posts_controller.rb I have

  def comment     Post.find(params[:id]).comments.create(params[:comment])     flash[:notice] = 'Added comment'     #render :action => show     redirect_to :action => show   end   

and in show.html.erb (the view) I have

<%= form_tag :action => 'comment', :id => @post %>   <%= text_area 'comment', 'body' %><br>   <%= submit_tag 'Post Comment' %> 

When I submit the form it tries to go to the urb /posts/comment/1 which is obviously incorrect, and it complains that it can’t find a template. Obviously I don’t want a template there because I’ve told it to redirect to the show action because I want it to just re-display the post’s show page, with the new comment there.

I’ve tried both the commented out line (render :action => show) and the redirect_to line, and neither seem to do anything at all.

I’m sure I’m missing something simple, but what is it?

Answer 1

Does redirect_to :action => 'show', :id => params[:id] with quotes around show work?
