I ran into something like this recently. If you’re in Rails and you have a method that takes keyword arguments and you have a strong params hash that you want to send to it, you can use symbolize_keys on the params hash and it will properly separate out the arguments, no double splat needed. Model … Read more
That doesn’t work because YAML allows you to specify keys of any type, so [activerecord, activemodel]: ‘test’ is a mapping with a single key, the sequence [activerecord, activemodel] whose value is ‘test’. Instead, you can use an anchor/alias: activerecord: &my_value ‘test’ activemodel: *my_value However, there’s no way of attaching both keys to the single value … Read more
As mentioned by others there’s no cross platform way to do this, but on Windows you can do it like this: The Code below checks if the key ‘A’ is down. if(GetKeyState(‘A’) & 0x8000/*Check if high-order bit is set (1 << 15)*/) { // Do stuff } In case of shift or similar you will … Read more
d = dict(zip(keys, values)) (Please don’t call your dict dict, that’s a built-in name.)
If you use Rails: Example with hash: camelCase to snake_case: hash = { camelCase: ‘value1’, changeMe: ‘value2’ } hash.transform_keys { |key| key.to_s.underscore } # => { “camel_case” => “value1”, “change_me” => “value2” } source: http://apidock.com/rails/v4.0.2/Hash/transform_keys For nested attributes use deep_transform_keys instead of transform_keys, example: hash = { camelCase: ‘value1’, changeMe: { hereToo: { andMe: ‘thanks’ … Read more
You could encrypt the private key with a symmetric key based on the users password. Simply store an additional salt and perform the password “hash” to get a separate key. Then use that as key for encrypting the private key. Note that it is required to use a Password Based Key Derivation Function (PBKDF) such … Read more
Tracing the source code of the 5.1 Source for the View Class. It would seem that dispatchKeyEvent() is the first method called by the system. Overloading it will prevent any and all key events from being called unless the base version is called. dispatchKeyEvent()‘s first move is to attempt to pass the event to an … Read more
There is no “error” if you use more than one key with the same name, but in JSON, the last key with the same name is the one that is going to be used. In your case, the key “name” would be better to contain an array as it’s value, instead of having a number … Read more
