rn0 / array-validation-error-mapping.php
Created Jun 8, 2017 — forked from webmozart/array-validation-error-mapping.php
A little experiment: Validating (potentially multi-leveled) arrays with the Symfony2 Validator component and returning the errors in the same data structure as the validated array by using the Symfony2 PropertyAccess component.

* around with this mechanism. In the subclass you will be able to give an
* entry for the discriminator map. In this listener we will retrieve the
* load metadata event to update the parent with a good discriminator map,

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

The introduction to Reactive Programming you've been missing

(by @andrestaltz)

So you're curious in learning this new thing called (Functional) Reactive Programming (FRP).

Learning it is hard, even harder by the lack of good material. When I started, I tried looking for tutorials. I found only a handful of practical guides, but they just scratched the surface and never tackled the challenge of building the whole architecture around it. Library documentations often don't help when you're trying to understand some function. I mean, honestly, look at this:

Rx.Observable.prototype.flatMapLatest(selector, [thisArg])

Projects each element of an observable sequence into a new sequence of observable sequences by incorporating the element's index and then transforms an observable sequence of observable sequences into an observable sequence producing values only from the most recent observable sequence.
