storytime | Rails 4 CMS and blogging engine | Application Framework library

so I've got a struct called 'library' that stores objects of the struct 'books', and is initialized by a list of 3 books, but when I try to print the object's attributes I get a "Segmentation fault (core dumped)" error. I understand that it means I'm trying to access some memory I don't have access to, but in this case I can access the first element correctly, so it makes me believe I initialized something incorrectly.

So everytime my reduces is called, it should update the state. This works and it pushes the new information in a new arrayposition.

But now I want to add a unique Id for each new added arrayposition. The problem is that it changes the initial state from 0 to 1, but only once. I'd like it to increment to 2,3,4,5,....

Question: can css detect the if an animation is incomplete?

storytime: I have a cool ui with animated buttons. they grow if you hover over them. therefore the other buttons in the button bar should shrink at the same time.

It is where I am uploading multiple images through Python Flask (this is all fine as the all selected images upload and save to the correct folder with correct name types etc.) The issue is saving the list of the images uploaded into a JSON. I have it so far where the value in the JSON is a list and it saves one image name to the list, but cannot seem to for loop through the other image names to save the others as well? I'm also not sure if the .split is correct in the storyTimeMap function in the Python file, I have used this in an other project and made sense to use it here? Any help is appreciated

does anyone know how to assign an Ionic2 Storage.get value to my local variable? If I console.log inside the .then, works fine, but it seems to only exist inside that function/method. Most examples I see, show how to 'get' my data but no really apply it to my other code

-thanks

I am trying to allow users the ability to update their profile, but can't seem to figure out how to only raise an error if the 2 fields username, email were modified, or if the user is not that user. As of now, I can't save the updates as the error is continuously popping up since the user has those values obviously. I've also tried excludes but couldn't get it to work right either. Here is my code:
