Question

我正在尝试利用remote: true来允许用户更新布尔值。以下内容可用于“选中”该框（将值更新为true），但在尝试“取消选中”该框（将值更新为false）时不起作用。

<%= check_box_tag("review[selected]", !review[:selected], review[:selected],  data: { remote: true, url: review_path(review.id), method: :patch } ) %>

如果未选中该框，而我选择了该框，则会看到以下日志：

Processing by ReviewsController#update as JS
  Parameters: {"review"=>{"selected"=>"true"}, "id"=>"89"}
  Review Load (0.3ms)  SELECT  "reviews".* FROM "reviews" WHERE "reviews"."id" = $1 LIMIT $2  [["id", 89], ["LIMIT", 1]]

但是，当我尝试取消选择该框（将其更新为false）时，我看到：

Processing by ReviewsController#update as JS
  Parameters: {"id"=>"89"}
  Review Load (0.3ms)  SELECT  "reviews".* FROM "reviews" WHERE "reviews"."id" = $1 LIMIT $2  [["id", 89], ["LIMIT", 1]]

ActionController::ParameterMissing (param is missing or the value is empty: review):

app/controllers/reviews_controller.rb:57:in `review_params'
app/controllers/reviews_controller.rb:28:in `update'

似乎参数没有通过？有没有办法解决这个内联问题？

带有远程复选框：true，无需使用JavaScript即可更新布尔值
