Validation messages after redirect

Question

Hello world!

We have a form to submit ratings for a certain restaurant in a in our views/restaurants/show.html.erb. If there is a validation error we get redirected back to views/restaurants/show.html.erb but the validation messages do not appear. We figured out that this happens because we lose the messages using redirect_to(@restaurant) in our RatingController create action. But how can we get back without redirection?

Thanks!

Answer 1

After your clarification in the comment, you need to setup your

/app/views/layouts/application.html.erb

with this line

<%- flash.each do |name, msg| -%><%= content_tag :div, msg, :id => "flash_#{name}" %><%- end -%>

Answer 2

You can pass your error on flash message

flash[:error] = @restaurant.errors

After you need display it in your redirect

Answer 3

You can use render instead of redirect_to

render :action => "show"

or set flash[:error], flash[:notice] again, because they automatically reseted
