Hola a todos,
llevo un tiempo peleandome con un error. Tiene pinta de basico asi que
se lo pongo aqui porque seguro que mucha gente puede resolverlo:
Tengo una clase Target:
class Target
attr_writer :hit_sequence_accession,
:hit_sequence_desc,
:hit_sequence_ID
attr_reader :hit_sequence_accession,
:hit_sequence_desc,
:hit_sequence_ID
def initialize(hit_sequence_accession,
hit_sequence_desc,
hit_sequence_ID)
@hit_sequence_accession = hit_sequence_accession
@hit_sequence_desc = hit_sequence_desc
@hit_sequence_ID = hit_sequence_ID
end
end
A la que le paso los valores 0, 1 y 0 mediante una consulta. Luego hago:
p @targets
p @targets[0].hit_sequence_ID
p @targets[0].hit_sequence_desc
p @targets[0].hit_sequence_accession
y esto es lo que me devuelve la consola:
[#<Target:0x48764c4
@attributes={"hit_sequence_desc"=>"0",
"hit_sequence_ID"=>"1
", "hit_sequence_accession"=>"0"}>]
nil
nil
nil
O sea, a traves de la llamada a @targets puedo ver los valores y los
nombres de los atributos, mientras que llamando a los atributos uno a
uno me devuelve nil.
Alguien sabe que estoy haciendo mal aqui??

Sorry I though I was on the Spanish forum. There it goes the english translation: I have a Target class:> > class Target > > attr_writer :hit_sequence_accession, > :hit_sequence_desc, > :hit_sequence_ID > > attr_reader :hit_sequence_accession, > :hit_sequence_desc, > :hit_sequence_ID > > def initialize(hit_sequence_accession, > hit_sequence_desc, > hit_sequence_ID) > @hit_sequence_accession = hit_sequence_accession > @hit_sequence_desc = hit_sequence_desc > @hit_sequence_ID = hit_sequence_ID > end > > end >To which I pass the values 0, 1 and 0 with and SQL sentence. Then I do:> > p @targets > p @targets[0].hit_sequence_ID > p @targets[0].hit_sequence_desc > p @targets[0].hit_sequence_accession >and this is what I get:> > [#<Target:0x48764c4 @attributes={"hit_sequence_desc"=>"0", > "hit_sequence_ID"=>"1 > ", "hit_sequence_accession"=>"0"}>] > nil > nil > nil >Calling the @targets collection directly gives me the correct values, while calling the attributes returns nil values. Anyone knows what I''m doing wrong here??
