Hi Jeurgen,
If you see my recent post i have the same issue
http://groups.google.co.uk/group/activescaffold/browse_thread/thread/84452e8c72c176da
Basically using AS with has many :through you cannot crete or edit
associations, AS does support HABTM but its not possible for me or you
by the sounds of
it to change all those relationships just to suit AS. My issue is the
same apart from i can see all the possible assocation options in the
check box list but if i edit any it just doesnt save. I did change
mine around like yours so i was then getting only the selected options
in the checkbox list but not the entire model. You should be able to
get this by changing :categorizations to :categories in your blog
controller but as i stated then the edit wont sane any updates. Will
see if any of the community come with something to help.
For your 2nd point you have a couple of options. Probably the easiest
is to exclude the exisiting show link like so and then add a new one
to your config.columns.
So in you blogs controller add :new_show to your exisiting columns
config.columns =
[:title, :body, :is_posted, :categorizations, :new_show ]
and in you blogs helper add something like the below to make the
new_show field an active link
config.columns :new_show
def new_show_column(record)
link_to "Show", :controller => 'blogs', :action => 'show', :id =>
record)
end
The other option is to overrite the partial that displays the action
links which may take a bit more time digging arouns.
