Answer 1

在您的用户控制器中，您必须具有以下内容：

def user_params
  params.require(:user).permit(:manager, :owner)
end

Answer 2

<label>Owner: </label><input type="checkbox" name="owner" value="1" />

如果选中该复选框，则所有者密钥将出现在post数组中。

要在提交表单后查看表单时选中复选框，您需要在复选框元素上添加checked="checked"作为属性。

Answer 3

您需要进入视图并为该特定字段创建复选框或单选按钮。在您看来，您可以这样做：

form_for @user do |f|
  f.label :owner
  f.check_box :owner
  f.submit
end

您可以根据需要将其包装在html代码中。

复选框参数提交但不插入
