您好我在 show.html.erb
中显示估算的预算我正在使用此代码:
<%= current_user.agency.project_procurement_management_plans.map{|p| p.total_estimated_budget.to_s} %>
然后,输出变为:
["117000.5"]
如何在[""]
因为数组(?)而打赌,但我怎样才能阻止它呢?
同样,当我在我的控制器中执行此代码时:
def create
@project_procurement_management_plan = ProjectProcurementManagementPlan.new(params[:project_procurement_management_plan])
respond_to do |format|
if @project_procurement_management_plan.save
format.html { redirect_to @project_procurement_management_plan, notice:"#{@project_procurement_management_plan.code} was successfully created." }
format.json { render json: @project_procurement_management_plan, status: :created, location: @project_procurement_management_plan }
else
#change me soon
format.html { redirect_to new_project_procurement_management_plan_path, alert:"#{@project_procurement_management_plan.errors.full_messages}"}
format.json { render json: @project_procurement_management_plan.errors, status: :unprocessable_entity }
end
end
end
错误消息位于[""]
E.g。
["Name can't be blank","The password is incorrect"]
等等。
任何变通办法都将受到赞赏。感谢。

是的,map
会返回包含所有元素的数组。如果您只有一个,则不应使用map
:
<%= current_user.agency.project_procurement_management_plans.first.total_estimated_budget.to_s %>
修改强>
对于错误
@project_procurement_management_plan.errors.full_messages.to_sentence
这会将您的错误与逗号以及和
