You need to first get the objects, before they can be tracked for changes. However, if all you're doing with the IQueryable is to update a member without touching anything else, it would be faster to just execute the UPDATE query.

Consider:

To execute a HTTP GET request for your Web API on the following URI in Angular:

var calendar = new Calendar .. already defined (in calendar.js)and it's Calendar. so if you re-define var calendar = document.getElementById('calendar'); in destroy.js.erb, the variable calendar is not Calendar anymore.

so 1. make sure calendar.js is imported.

and 2. remove re-define calendar

Your problem is that you have set SESSION_CONNECTION=session, but your SESSION_DRIVER=default, so you have to use SESSION_DRIVER=database in your .env. See the config/session.php:

Aggregate the Transactions table separately, then JOIN Users only afterwards:

I think I have some idea regarding it. What you can do is store the list like.

This question is really too big for Stack Overflow.

But one way of answering it is to say that if you can mechanically translate some variant of λ-calculus into some other language, then you can reduce the question of how you might compile λ-calculus to asking how do you turn that substrate language into machine language for some physical machine: how do you compile that substrate language, in other words. That should give an initial hint as to why this question is too big.

Fortunately λ-calculus is pretty simple, so the translation into a substrate language is also pretty easy to do, especially if you pick a substrate language which has first-class functions and macros: you can simply compile λ-calculus into a tiny subset of that language. Chances are that the substrate language will have operations on numbers, strings, and all sorts of other types of thing, but your compiler won't target any of those: it will just turn functions in the λ-calculus into functions in the underlying language, and then rely on that language to compile them. If the substrate language doesn't have first-class functions you'll have to work harder, so I'll pick one that does.

So here is a specific example of doing that. I have a toy language called 'oa' (or in fact 'oa/normal' which is an untyped, normal-order λ-calculus. It represents functions in a slight variant of the traditional Lisp representation: (λ x y) is λx.y. Function application is (x y).

oa then get gets turned into Scheme (actually Racket) roughly as follows.

First of all there are two operations it uses to turn normal-order semantics into Scheme's applicative-order semantics:

• (hold x) delays the evaluation of x – it is just a version of Scheme's delay which exists so I could instrument it to find bugs. Like delay, hold is not a function: it's a macro. If there were no macros the translation process would have to produce into the expression into which hold expands.
• (release* x) will force the held object made by hold and will do so until the object it gets is not a held object. release* is equivalent to an iterated force which keeps forcing until the thing is no longer a promise. Unlike hold, release* is a function, but as with hold it could simply be expanded out into inline code if you wanted to make the output of the conversion larger and harder to read.

So then here is how a couple of λ-calculus expressions get turned into Scheme expressions. Here I'll use λ to mean 'this is a oa/λ-calculus-world thing' and lambda to mean 'this is a Scheme world thing'.

As mentioned in the comments of the question, the answer is that I needed to be using a bash session, but was in fact using a zsh session.

Figured this out thanks to @Barmar by running echo $SHELL

As @Shawn mentioned:

== isn't understood by a basic POSIX-only test/[ (Or by zsh's implementation)

Running chsh -s /bin/bash to change from zsh to bash fixed it, and then I had to reopen the terminal for it to actually take effect (this may not be necessary for everyone, but at least for me using Hyper as my terminal emulator, the change didn't take effect until closing and reopening the app).
