Simple queries against JSON-like in-memory data structures.
Add this line to your application's Gemfile:
gem "json_query"And then execute:
$ bundle
Or install it yourself as:
$ gem install json_query
require "json_query"
data = {
"foo" => "bar",
"spam" => {
"eggs" => [
{"name" => "qui", "password" => "x"},
{"name" => "quo", "password" => "y"},
{"name" => "qua", "password" => "z"}
]
}
}
JsonQuery.perform(data: data, query: "oo")
# => [{:path=>"foo", :value=>"bar"}]
JsonQuery.perform(data: data, query: "foo")
# => [{:path=>"foo", :value=>"bar"}]
JsonQuery.perform(data: data, query: "sp.egg[nam=qui].pass")
# => [{:path=>"spam.eggs[0].password", :value=>"x"}]
JsonQuery.perform(data: data, query: "sp.egg[nam=qui]")
# => [{:path=>"spam.eggs[0]", :value=>:set}]
JsonQuery.perform(data: data, query: "sp.egg[nam=qui]", deep: true)
# => [{:path=>"spam.eggs[0]", :value=>{"name"=>"qui", "password"=>"x"}}]
JsonQuery.perform(data: data, query: "sp.eggs", deep: true)
# => [{:path=>"spam.eggs", :value=>[{"name"=>"qui", "password"=>"x"}, {"name"=>"quo", "password"=>"y"}, {"name"=>"qua", "password"=>"z"}]}]
JsonQuery.perform(data: data, query: "sp.egg[1].name")
# => [{:path=>"spam.eggs[1].name", :value=>"quo"}]
JsonQuery.perform(data: data, query: "sp.egg[name=qu&pass=x].name")
# => [{:path=>"spam.eggs[0].name", :value=>"qui"}]
JsonQuery.perform(data: data, query: "asd")
