Rails - how to pass created record from the new form to a redirected page -


i think pretty simple question nothing i've read has answered question directly:

i have new products page standard form. after submitting form, redirect custom controller action , view called "thanks".

on "thanks" page, want able print name of product created , possibly other attributes.

how pass object created new action? right controller looks this:

def create     @product = product.new(params[:product])     if @product.save     flash[:notice] = "successfully created product."     redirect_to thanks_path     else     render :action => 'new'     end end  def end

you can't send object through redirect.

there 3 ways solve problem:

  1. render 'thanks' template directly(not action #thanks)

    render 'thanks' # template

    you can send whatever instance variable template directly. #thanks no longer needed in case.

    drawback: url won't changed.

  2. convey messages through session

    if want show messages, can prepare in #create , send through session or flash(part of session actually). flash better don't need clear manually.

    note: may want use activerecord session storage if message size big, otherwise you'll meet cookiesoverflow default setting.

  3. send simple message through session obj_id

    similar #2 thinks better #2. in #thanks, can construct complex message according if obj_id present, id , find related data through db.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
