George, I will try to reply to your previous post to the list later, and I gotta admit I haven't got enough time now to think about your question in this thread. However, I found
http://wonderfullyflawed.com/2009/02/17/rails-forms-microformat/ to be a very nice article that explains how params should be constructed and sent, in case you want to work with nested model assignment. It's definitely worth a read, imho. cheers snusnu On Mon, Dec 7, 2009 at 15:07, George Adamson <[email protected]> wrote: > After some investigation it seems that submitted fields names are not > parsed as expected. > > If the post includes more than one field with the same name, only one > of them (the latter) will be present in the params hash when the form > is submitted. > > For example the request.raw_post may contain: > trip[countries][id]=1&trip[countries][id]=2&trip[countries][id]=3 > > ...but the params hash will only contain: "countries"=>{"id"=>"3"} > I would expect something like: "countries"=>[{"id"=>"1"}{"id"=>"2"} > {"id"=>"3"}] > (The Merb::Parse.query method seems to be responsible for this.) > > Ideally merb would handle the update of trip.countries but at the very > least we should have an array of trip countries to loop through to > update the countries. > > Is this a bug or have I misunderstood? > (The scenario is a bunch of checkboxes on a Trip page, allowing the > user to choose one or more countries.
