I have a fields_for tag, where I specify the prefix (lets say for some good reasons), and this is supposed to represent a one-to-one relationship.
I am trying to represent a relationship
widget has_many thingamagigs
thingamagig has_one whatchamacallit
The field_for code is:
fields_for "widgt[thingamagigs_attributes][][whatchamacallit_attributes]", thingamagig.whatchamacallit do |x|
which generates names (wrongly):
widget[thingamagigs_attributes][][whatchamacallit_attributes][][value]
The better solution would be
t.fields_for :whatchamacallit do |x|
where t = fields_for the thingamagig... However if I do that, the following names are generated
widgt[thingamagigs_attributes][whatchamacallit_attributes][]
which is completely wrong as all other fields for a thingamagig is...
widgt[thingamagigs_attributes][][name]
So in all cases I am screwed. The original field_for using a string cannot be used with accepts_nested_attributes_for :whatchamacallit
since whatchamacallit is a singular relationship and an object is expected not an array. The second fields_for will simply not work because rails cannot parse the params object correctly. Is there a way to tell the first forms_for to not add the [] after [whatchamacallit_attributes]
in all field names?
My current solution is to augment the model with
def whatchamacallit_attributes=(whatchamacallit_attributes)
assign_nested_attributes_for_one_to_one_association(:whatchamacallit, whatchamacallit_attributes[0])
end
Which will work even with the broken form fields. However this feels extremely hacky, does anyone have a solution?
