Ruby on rails 无法将哈希对象与ActiveSupport:：HashWithInferenceTaccess合并

我有一个哈希对象（类名哈希）：

我有一个params对象（类名ActiveSupport:：HashWithInferenceTaccess）

我想用deep_merge合并这些对象

h1.深度合并（h2）

然后我得到：

{
 :hot_products=>{:enabled=>true, :always_enable=>false, :order=>0},
 :recent_products=>{:enabled=>true, :always_enable=>true, :order=>1},
 :event_promotion=>{:enabled=>true, :always_enable=>false, :order=>2},
 "hot_products"=>{"enabled"=>"1"},
 "recent_products"=>{"enabled"=>"0"},
 "event_promotion"=>{"enabled"=>"1"}
}

有人知道如何合并这两个对象吗？

问题是

h1

有符号键，

h2

有字符串键

将

h1

设为

hashwithindifferenceaccess

h1 = {
 :hot_products=>{:enabled=>true, :always_enable=>false, :order=>0},
 :recent_products=>{:enabled=>true, :always_enable=>true, :order=>1},
 :event_promotion=>{:enabled=>true, :always_enable=>false, :order=>2}
}.with_indifferent_access

及

现在，您可以

deep\u merge

散列，它将返回正确的结果

h1.deep_merge(h2)

{
 "hot_products"=>{"enabled"=>"1", "always_enable"=>false, "order"=>0},
 "recent_products"=>{"enabled"=>"0", "always_enable"=>true, "order"=>1}, 
 "event_promotion"=>{"enabled"=>"1", "always_enable"=>false, "order"=>2}
}

 "event_promotion"=>{"enabled"=>"1", "always_enable"=>false, "order"=>2}
}

试试这个

h1=ActiveSupport::HashWithIndifferentAccess.new(h1)
h1.deep_merge(h2)
=> {"hot_products"=>{"enabled"=>"1", "always_enable"=>false, "order"=>0}, "recent_products"=>{"enabled"=>"0", "always_enable"=>true, "order"=>1}, "event_promotion"=>{"enabled"=>"1", "always_enable"=>false, "order"=>2}} 

试试这个

h1=ActiveSupport::HashWithIndifferentAccess.new(h1)
h1.deep_merge(h2)
=> {"hot_products"=>{"enabled"=>"1", "always_enable"=>false, "order"=>0}, "recent_products"=>{"enabled"=>"0", "always_enable"=>true, "order"=>1}, "event_promotion"=>{"enabled"=>"1", "always_enable"=>false, "order"=>2}}
