hi thanks a lot for your help so far.
I got most of my problems fixed tonight but just have one tiny issue
left. When I go to the create form to write a new post, the users
drop-down menu is populated with data of the following form: "#<User:
0x9d58ce4>". I'd like the username of the user to appear here instead
of "#<User:0x9d58ce4>"
The exact same thing was happening in the list and show views whenever
the user was referenced, but I fixed that by overriding the
user_column method in my model:
def user_column(record)
if record.user.nil?
active_scaffold_config.list.empty_field_text
else
record.user.username
end
end
I tried to do something similar (see code below) to override the
user_form_column method but rails complains about there being no
username method
def user_form_column(record, input_name)
select(:record, "record.user.username", :name=> input_name )
end
So I think I'm close but can't quite get my head round what I need to
do to make usernames appear in the create/edit form for the posts
resource.
Does anyone know how to fix this? Thanks in advance,
