Rails - Aug 2012 - undefined method `with_indifferent_access' for "":String

Hi

I''m having a issue with one object when try to update the attributes in
this object previously saved in the database

I have one object comp and one object reg they have this relationship

comp

has_many regs

reg

belongs_to comp

when run use the method valid? like this

  current_contribuyente.comps.build(params[:comp]).valid?

it returns: IndexError (string not matched)

And when I try to update directly the comp directly it return this
error:
@comp = current_contribuyente.comps.find(params[:id])

@comp.update_attributes(params[:comp])

NoMethodError (undefined method `with_indifferent_access'' for
"":String):


This is the code from the view where I create this elements

= form_for @comp, :html => {:id => "new_form", :onsubmit =>
"return
validate_form()"}, :remote => true do |f|

= f.fields_for :comprobante_emis_regs_attributes do |cer|
              = cer.collection_select :reg_fil,
current_contribuyente.contribuyente_regs, :reg_fil, :reg_fil,
{:include_blank => false}, :class => ''reg_fil'', :name
=>
"comp[comp_emis_regs_attributes][0][reg_fil]"


Somebody has run into this issue i''m really running out of ideas of how
to fix this.

current_contribuyente is a method that works similar to current_user 
work like these:

def current_contribuyente
  current_user.contribuyente
end

it just a custom current_user that retrieves a model (contribuyente) for 
the current_user

contribuente has_many :comps

Hi arturo drlt,

Try without "fields_for"
It really works! ;-)

I always had troubles writing the code for this model using only 
collection_select

so far i have this code:

- if comp_exist
              = collection_select(:comp, :comp_emis_regs_reg_fil, 
current_contribuyente.contribuyente_regs, :reg_fil, :reg_fil, 
{:include_blank => false})
            - else
              = collection_select(:contribuyente, 
:contribuyente_regs_reg_fil, current_contribuyente.contribuyente_regs, 
:reg_fil, :reg_fil, {:include_blank => false}, {:class =>
''reg_fil'',
:name => "comp[comp_emis_regs_attributes][0][reg_fil]"})

and the first collection_select return this error
undefined method `comp_emis_regs[0].reg_fil'' for
#<Comp:0x7f90f655ca38>

because the method :comp_emis_regs_reg_fil its really one array and i 
don''t know how to specify the method for the reg_fil attribute inside 
:comp_emis_regs because the relationship is has_many, some ideas?

undefined method `comprobante_emis_regs_reg_fil'' for 
#<Comp:0x7f90f6298ae0>

current_contribuyente.contribuyente_regs, :reg_fil, :reg_fil, 
{:include_blank => false})

UPDATE


code:

collection_select(:comp, :comp_emi_reg_ids, CompEmiReg.where("comp_id = 
?", @comp.id), :id, :reg_fil, {:include_blank => false})

return this error

NoMethodError (undefined method `with_indifferent_access'' for 
"":String):

and this code:

collection_select(:comp, :comp_emi_reg_ids, CompEmiReg.where("comp_id = 
?", @comp.id), :reg_fil, :regi_fil, {:include_blank => false})

return this error:
ActiveRecord::RecordNotFound (Couldn''t find CompEmiReg with ID=0):

I tried to do this

collection_select(:comp, :comp_emi_reg_regs_fils, 
CompEmiReg.where("comp_id = ?", @comp.id), :reg_fil, :regi_fil, 
{:include_blank => false})

but it don''t wokrs it returns:

NoMethodError: undefined method `comp_emi_reg_regs_fils'' for 
#<Comp:0x7ffd398b58d8>

it seems that in the param of method for collection I only can send the 
attribute id in plural other fields just return NoMethodError, I don''t 
know what I''m doing wrong at the end always end up with NoMethodError 
(undefined method `with_indifferent_access'' for "":String):

somebody knows another way to do this or knows if in the param method it 
only can receive ids for this kind of relationship?
