奇怪的“无法批量分配受保护的属性”错误

Question

Im running into the following error

Can't mass-assign protected attributes:

I know this is a generally asked question, but none of the answers provided seem to work for me. The thing is, i already have this 2 lines in my "parent" model:

accepts_nested_attributes_for

AND

attr_accessible  :childmodel_attributes

I had run into this error in the past, and those 2 lines succefully solved the issue.. But they dont now. BTW, the "protected attributes" are ALL the fields in my "child" model, not just certain ones.

Hope someone can help me, im stuck and dont know what else to do.

This is the full error line:

Can't mass-assign protected attributes: linea, origen_comp, conector, char_ini, char_fin, modopremio_id, codigo_opc, ochar_ini, ochar_fin

This is what the "child_model" has

:consorcio_id, :productosacierto_id, :clave, :linea, :origen_comp, :conector, :char_inic, :char_fin, :modopremio_id, codigo_opc, :ochar_ini, :onchar_fin

(Sidenote, the "parent/child model" names are just for reference, they are not their true names (productosacierto AND productosregla) would be it.

Parent Model (Productosacierto)

has_many :productosregla
accepts_nested_attributes_for :productosregla, :reject_if => :all_blank, :allow_destroy => true
attr_accessible  :productosregla_attributes, :producto_id, :consorcio_id, :clave, :descripcion, :una_condicion
default_scope order: 'id'
self.table_name = "hproductos_aciertos"

Child Model (Productosregla)

self.table_name = "hproductos_reglas"  
belongs_to :productosacierto
attr_accessible :consorcio_id, :productosacierto_id, :clave, :linea, :origen_comp, :conector, :char_inic, :char_fin, :modopremio_id, codigo_opc, :ochar_ini, :ochar_fin 
default_scope order: 'id'

Answer 1

如果这是您的子模型的精确副本，那么我想attr_accessible行末尾的逗号就是问题所在！

Answer 2

I feel kind of embarrassed right now. There were several sintax errors on my model and thats what was causing this issue. I took it for granted that rails would throw a sintax error if there were some, specially when it's so delicate when it comes to writting code in the model...

This is what i had:

attr_accessible :consorcio_id, :productosacierto_id, :clave, :linea, :origen_comp, :conector, :char_inic, :char_fin, :modopremio_id, codigo_opc, :ochar_ini, :ochar_fin

This is what it was supposed to be:

attr_accessible :consorcio_id, :productosacierto_id, :clave, :linea, :origen_comp, :conector, :char_ini, :char_fin, :modopremio_id, :codigo_opc, :ochar_ini, :ochar_fin 

As you can see, there was a ":" missing before the codigo_opc param, and also the char_ini param had an extra "c" that didnt belong. Thanks everyone who helped, this taught me to make sure never to assume anything.
