我正在尝试向 2 个表提交表单,但不知何故我收到了此语法错误unexpected '\n'
在这条线上joins: ['sources'], :landslide_id
and found unpermitted parameter: sources
在滑坡参数中。这是所有文件
Models
class Landslide < ApplicationRecord
has_many :sources, dependent: :destroy
accepts_nested_attributes_for :sources
class Source < ApplicationRecord
belongs_to :landslide
end
山体滑坡控制器.rb
def new
@landslide = Landslide.new
@landslide.sources.build
end
# POST /landslides
def create
@landslide = Landslide.new(landslide_params)
@landslide.save
end
private
# Use callbacks to share common setup or constraints between actions.
def set_landslide
render json: Landslide.find(params[:total_id]),
joins: ['sources'], :landslide_id
end
# Only allow a trusted parameter "white list" through.
