i have listed my _form.html.erb file below what i would like to do is change the text on the submit button i know how to do it in html but not shure how to do it in Rails 3<
Building on @daniel's answer, you can also customize submit tag values on a per-model basis:
en: helpers: submit: model_name: create: "Create" update: "Update"
And then in your form you can just use:
<%= f.submit %>
See here for the documentation (second example.)
