RJS - page object in helpers?
Hello,
I am using RJS and Edge Rails and I was wondering if the page object should

end
and then in my RJS files I call

Autocompleter enhancement feature request
Hello,
I have created a ticket for an enhancement of the autocompleter to show the
options immediately when the field gets focus. Right now at least one
character must be typed for autocomplete to kick in.
http://dev.rubyonrails.org/ticket/5435
I have also made some code changes directly in the script
Event.observe(this.element, "blur", this.onBlur.bindAsEventListener(this));

rails migrations - enhanced usage
Hello,
When I am writing rails migrations, quite often I make mistake in them which
causes the migration tasks to stop halfway with error.
This causes lots of problem, because it results in half of the things in
migrations changed and other half not. Also, as the schema number is changed,
so things cannot be rolled back.
Is there any way to make the entire migration action atomic, i.e.,

page_size = 20

Problem with Pagination

I am trying to paginate the results from a search. When I use actual
constants in the search conditions, it works fine:

use join table in paginate
How come I allways immediately run into difficult stuff when I''m trying
some new programming language? Am I blind for the simplicity of
Ruby/Rail, which a see must be there? Anyway, don''t try and answer this
rhetoric question. I have got another one for you, seemingly difficult.
I''m struggling with a n:m relationship (in a database, that is) and its
join table.
