I've been trying to use the :select option on an association to add in some
fields from a join table, but it was giving me an error with the :select (not
without).
The example from the docs:
User.many_to_many :films,
:left_key => :user_id,
:right_key => :film_id,
:join_table => :users_rel_films,
:select => [ Sequel.expr(:films).*,
:users_rel_films__no_of_views,
:users_rel_films__demand],
:class => :"App::Film"
> Error: ArgumentError: wrong number of arguments (0 for 1)
So I tried a few things in the console:
Sequel.expr(:films).* # according to the docs this should return "films".*
> ArgumentError: wrong number of arguments (0 for 1)
In case it's something to do with that table, I tried:
Sequel.expr(:schema_info).*
> ArgumentError: wrong number of arguments (0 for 1)
but this works:
Sequel.expr(:schema_info).* 2
> => #<Sequel::SQL::NumericExpression @op=>:, args=>[#<Sequel::SQL::Wrapper
> @value=>:schema_info, 2]
This is ok too:
Sequel.expr(:schema_info)
> => #<Sequel::SQL::Wrapper @value=>:schema_info
I've tried a few other things but they all give either the same error or syntax
errors.
The sequel version is 3.36.1
I'm sure I must be doing something silly, but I can't work out what. Any help
with this is much appreciated.
Regards,
Iain
