प्रोग्रामिंग, सवालों के जवाब में मदद करें / माणिक / मिस्केल विफलता से रूबी वस्तु का वर्णन करना: विधि (टाइपऑयॉर) के लिए आवंटित अपरिभाषित - रूबी, क्रमबद्धता, यमल

YAML विफलता से रूबी ऑब्जेक्ट Deserializing: विधि के लिए अपरिभाषित आवंटक (TypeError) - रूबी, serialization, yaml

मैं एक खेल की वर्तमान स्थिति को बचाने की कोशिश कर रहा हूँ। मैं एक नई फ़ाइल और लेखन बनाकर YAML में game_state ऑब्जेक्ट को क्रमबद्ध करता हूं YAML::dump(game_state)। मैं तब इस कोड का उपयोग इसे deserialize करने के लिए करता हूं:

input = YAML.open(@text_input.to_s + ".yml", "r")
playstate = YAML.load(input.read)
puts playstate

मुझे यह त्रुटि रनटाइम पर मिली

C:/Ruby192/lib/ruby/1.9.1/psych/visitors/to_ruby.rb:227:in `allocate": allocator
undefined for Method (TypeError)
from C:/Ruby192/lib/ruby/1.9.1/psych/visitors/to_ruby.rb:227:in `revive"

from C:/Ruby192/lib/ruby/1.9.1/psych/visitors/visitor.rb:7:in `accept"
.......
(I can post the whole trace if necessary)

तो, क्या मेरा YAML खराब स्वरूपित है? यह इसके साथ मेरा पहला अनुभव है, इसलिए स्टैक ट्रेस "वास्तव में मेरे लिए बहुत मायने रखता है। किसी भी मदद की सराहना की है

यह मेरी YAML फ़ाइल है जो game_state के लिए दिखती है।

उत्तर № 1 के लिए 1

मैं बस एक ही रास्ते से नीचे चला गया। फ़ॉर्म की लाइनों के लिए अपनी YAML फ़ाइल देखें:

action: !ruby/object:Proc {}

YAML "lambdas या procs (वहाँ नहीं" के साथ सौदा नहीं कर सकताउन्हें सिलसिलेवार तरीके से समझदार तरीका)। यदि आपके पास उस कोड तक पहुंच है जो YAML "डी ऑब्जेक्ट जनरेट करता है, तो शायद आप लैम्बडा को एक वास्तविक ऑब्जेक्ट और मेथड कॉल से बदल सकते हैं?

उदाहरण के लिए, यदि कोड जो इस YAML डंप को उत्पन्न करता है:

icon = PlanetDefense::RingMenu::Icon.new
icon.action = lambda {|arg1| do_something_with(arg1)}

आप एक वर्ग को लिखने में सक्षम हो सकते हैं जिसका एकमात्र काम लंबोदर को बदलना है

class IconAction
def call(arg1)
do_something_with(arg1)
end
end
...
icon = PlanetDefense::RingMenu::Icon.new
icon.action = IconAction.new
