我尝试更新iproduction,一个来自生产的嵌套表单,我在这行中有一个params的错误: "错误的参数数量(0表示1)"
@ production.update.iproductions_attributes(cow_id:@cow)
我的创作动作制作:
def create
@production = @ranch.productions.create(production_params)
@production.update(date: Date.today)
@cows = @ranch.cows
@cow = Cow.find_by(id: params[:id])
@production.update.iproductions_attributes(cow_id: @cow)
respond_to do |format|
if @production.save
format.html { redirect_to ranch_production_path(@production.ranch_id, @production), notice: 'Production was successfully created.' }
format.json { render :show, status: :created, location: @production }
else
format.html { render :new }
format.json { render json: @production.errors, status: :unprocessable_entity }
end
end
end
你能帮我解释一下语法吗?
答案 0 :(得分:1)
应为@production.iproductions.update_attributes(cow_id: @cow)
def create
@production = @ranch.productions.create(production_params)
@production.update(date: Date.today)
@cows = @ranch.cows
@cow = Cow.find_by(id: params[:id])
@production.iproductions.update_attributes(cow_id: @cow)
respond_to do |format|
if @production.save
format.html { redirect_to ranch_production_path(@production.ranch_id, @production), notice: 'Production was successfully created.' }
format.json { render :show, status: :created, location: @production }
else
format.html { render :new }
format.json { render json: @production.errors, status: :unprocessable_entity }
end
end
end
