rails form_for 加载时客户端验证错误

Question

我正在尝试在 Rails 中使用客户端验证 Gem。我的表单一直有效，直到将 `:validate => true" 添加到我的 form_for 中。然后我收到一个错误消息，告诉我我编写它的方式是错误的。我尝试像示例一样重新格式化它，它只是抛出错误。

错误

Using form_for(:name, @resource) is not supported with ClientSideValidations. Please use form_for(@resource, :as => :name) instead.

我认为你应该为表单创建一个新对象

在新操作中添加@hash_create = HashTag.new 并将您的表单更改为

form_for(@hash_create, :url => hashtags_path, :validate => true, remote: true)
