如何正确添加记录。image\u integrity\u现有条件错误?

历史记录: How to display a presence validation conditionally in combination with carrierwave?

我正在用这个宝石构建一个对象: https://github.com/schneems/wicked/wiki/Building-Partial-Objects-Step-by-Step

validates :name,      :presence => true, :if => :active_or_name?
validates :details,   :presence => true, :if => :active_or_details?
validates :image,     presence: true, image_size: { width: { min: 400 }, 
  height: { min: 400 } }, :file_size => { :maximum => 5.megabytes.to_i }, 
  if: :active_or_details?

具有以下功能:

def active?
  status == 'active'
end

def active_or_name?
  status.include?('name') || active?
end

def active_or_details?
  status.include?('details') || active?
end

我如何设置状态:

params[:item][:status] = step.to_s
params[:item][:status] = 'active' if step == steps.last

最后一步是详细信息页面后的2步,因此它不应处于“活动”状态。

在历史记录(上面的链接)中,您可以看到我应该将以下内容添加到 if: 图像验证的:

-> (record) { record.image_integrity_error.blank? }

我试着用

validates :image,     presence: true, image_size: { width: { min: 400 }, 
height: { min: 400 } }, :file_size => { :maximum => 5.megabytes.to_i },
if: :active_or_details? && -> (record) { record.image_integrity_error.blank? }

这会导致页面上的验证仅显示 Image You are not allowed to upload "txt" files, allowed types: jpg, jpeg, gif, png

但现在,验证将在之前需要的提交步骤的每一页上进行 Image can't be blank .

我试图重构 -> (record) { record.image_integrity_error.blank? } 进入 active_or_details? 使用if/else语句。然后 图像不能为空 在详细信息页面上返回。

请告知。
