My personal preference is to use simple_form and have it put the error next to the input. share|improve this answer answered Jul 15 '13 at 20:41 Jesse Wolgamott 36k36194 add a comment| up vote 20 down vote This is how I am displaying them for my form object called @location: <% if @location.errors.any? %>

I'm stumped... displaying error messages Started by Rowel , Sep 07 2013 11:02 PM Please log in to reply 4 replies to this topic #1 Rowel Rowel Controller Members 109 posts Posted 07 September 2013 - 11:02 PM Help. I'm stumped and couldn't figure this out. I'll try to explain the problem as clearly as I can. Given: I have a users page (views/users/show.html.erb) http://localhost:3000/users/24 where 24 is user_id , for example On this page, I'm displaying all his posts and some user profile information. These work fine. # display user profile def show @user = User.find(params[:id]) # get this user's friends list @friends = @user.friends # get all posts by this user, with paging @posts = @user.posts.paginate(page: params[:page]) end On the same user page (view/users/show.html.erb), I also have an online form. <%= form_for(:post, url: posts_path, method: :post) do |f| %> <%= render 'shared/error_messages'%> ... <% end %> It calls posts_path. and In my posts controller, I have this. def create @post = current_user.posts.build(post_params) if @post.save # success end # @post.save redirect_to current_user end This too, works fine... I can create new posts record, browser redirects to the user's page again, and my new post is listed on the screen. on Post, I have some model validations. They also work fine. validates :title, presence: true, length: { minimum:5, maximum: 140 } validates :post, presence: true, length: { minimum:5 } The problem is if there's an error, (for example, it didn't meet the field length requirements), I want to display an error message on the users page. The validations errors should be in @post.errors How can I display these @post.errors in the /users page? I tried this. This doesn't work... <%= render 'shared/error_messages'%> _error_messages.html.erb <% if @post.errors.any? then %>
Ooops! this is error message partial
<% end #errors.any? %> Back to top Report #2 Rowel Rowel Controller Members 109 posts Posted 08 September 2013 - 01:02 AM I say to hell with it... I just stored the error messages in a session variable, redirected back to the user page, and displayed the errors stored in the session variables.
