Strong options for has_one nested association
I seem to be missing something, but I cannot resolve the nested association attributes has_one
.
Controller:
def create
@crossword = Crossword.new(crossword_params)
if @crossword.save
render :show, status: :created, location: [:api, @crossword]
else
render json: @crossword.errors, status: :unprocessable_entity
end
end
def crossword_params
params.require(:crossword).permit(:title, :grid_size, grid_size_attributes: [:rows, :columns])
end
Model:
validates :title, :grid_size, presence: true
validates_associated :grid_size
has_one :grid_size
accepts_nested_attributes_for :grid_size

Am I missing something trivial? It seems like everyone is talking to do it.

Change "grid_size" to "grid_size_attributes" in your POST body.
If you want to continue using "grid_size", update your method crossword_params
:
def crossword_params
params[:crossword][:grid_size_attributes] = params[:crossword][:grid_size] if params[:crossword][:grid_size]
# NOTE :grid_size removed!
params.require(:crossword).permit(:title, grid_size_attributes: [:rows, :columns])
end
