Hi i got a problem that object has its fields initialize but no the
reference to the objects,
the table has its own id, and has 2 references keys, but i got only
the fields not the objects
so i have to query to bring it,

module TodostagsHelper

def viewtags(todo_)

tags =""
todo_.todostags.each do |todotag_|

##prints ok the todotag_tags_id
puts “imprimiendo #{todotag_.tags_id}”
##prints nil to the object todotag_.tag , its suppose to be initialize
not?
puts todotag_.tag

  tip = Tag.find(todotag_.tags_id)
  tags=  tags.concat(',').concat(tip.name)

end


tags

end

end

for table tags
id pk
name string
description string
for table todos
id pk
todo string
progreso string
vencimiento date
for table todostags
id pk
todos_id fk
tags_id fk

It should be, but as your code stands it will be using tag_id to find
a Tag object whereas the rest of your code is examining tags_id. What
columns are actually on the table?
