如何将新哈希插入到ruby中的现有哈希中

Question

我有两个哈希：

p = {"name"=>"TRICHI", "subdistrict"=>{"WANDIWASH"=>"1234"}}
q = {"name"=>"VELLORE", "subdistrict"=>{"WANDIWASH"=>"4183"}}

我需要将其作为

r = [{"name"=>"VELLORE", "subdistrict"=>{"WANDIWASH"=>"4183"}}, 
    {"name"=>"TRICHI", "subdistrict"=>{"WANDIWASH"=>"1234"}}] 

Answer 1

我想你想要这个：

r = [] << p << q
# or r = [p, q]
# either way you'll get:
#  [ {"name"=>"VELLORE", "subdistrict"=>{"WANDIWASH"=>"4183"}},
#    {"name"=>"TRICHI", "subdistrict"=>{"WANDIWASH"=>"1234"}}  ]

通过这种方式，您将拥有array个hashes。

Answer 2

Tim指出，r似乎不是哈希，也许你的意思是一个数组，在这种情况下你可以做

r = [p,q]

或

r = []
r << p
r << q
.. keep going for any other entry you want to push into r
