That does make sense, and doesn't mess with the browsing history (aka
backbutton mess).
As for the error messages, I remember from Django (let's forget for a
moment that it's completely different from anything you have in Ruby)
you could really easily create your own "helper" for rendering form
fields, and could thus implement a generic way of showing error messages
next to the corresponding field in the form. Maybe there's something
half way similar in Merb? I guess I could wrap merb's form helper
methods, but that seems hacky.
The output I eventually want to obtain would be something along the
lines of...
<form....>
<p>
<label...>
<input .....>
<!-- if @model.errors['whatever'] -->
<p class="error">Field can't be empty</p>
</p>
</form>
I guess this might not be as common as to deserve a core helper, but
maybe I'm overlooking something?
