What I'm trying to do is to get the @pmcs and @ppmcs variables sent to the view
from discuss, vote, and invite. The roster example shows no variables outside
the do... end blocks. The code to calculate these is simple but not trivial.
So would you recommend doing the calculation in the common code and setting the
@variables in the do... end block. E.g.
pmcs = ASF::Committee.pmcs.map(&:name).sort
ppmcs = ASF::Podling.list
.select {|podling| podling.status == 'current'}
.map(&:name).sort
get '/discuss' do
@view = 'discuss'
@pmcs = pmcs
@ppmcs = ppmcs
_html :app
end
get '/vote' do
@view = 'vote'
@pmcs = pmcs
@ppmcs = ppmcs
_html :app
end
