pugs | A Perl 6 Implementation

I have a function that adds an image on mousedown when clicking a circle inside my canvas. Now every time I click the circle a new image gets added which is not what I want. I'd like some sort of toggle function so it removes the image on second click and adds a new one the third time and so on.

My function at the moment looks like this:

I have an array of objects which want to convert it to JSON tree structure by java script function and then use it in a vue js project. The page have a vuetify tree component which need JSON tree structure. My data have been stored in MySql table with parent child structure.

Sample Date :

I have 3 commands. !disablepugs, !enablepugs and !join. !disablepugs set's a variable to False, and !enablepugs sets a variable to true. However, the variable is changed just fine. But, when I check if the variable is equal to True in the !join command, it's still not detecting the change. Code:

I have added a new image to a card and when I do a search, the card gets squished. Can't figure out if it's grid related to Bootstrap or an issue with image size. I appreciate anyone that has suggestions what I can do to fix this. I have tinkered with .card-top-img css rules but that doesn't work. I have tried different grid options.

JSFiddle for the code

I have built out a page with cards using Bootstrap 4. I am able to search the cards and it returns only the ones with titles that match. the issue I am running into is 1. Two cards on the same row that match will overlap and 2. if it's on another row it doesn't move up to the first trow. I have tried a lot of different things, but have not been successful with making this work correctly. Looking for some help with what I need to do or at least where to look.

So I have successfully implemented a user authentication using Passport.js.
Right now I am trying to implement a random URL generator for resetting passwords/confirming accounts/etc. But I cannot seem to reference the database table through Sequelize.

How do I reference an already-defined model in Sequelize outside the module it was defined in?

In the code below user is passed via function(passport, user). Adding a third parameter to its call in server.js (e.g. require('./app/config/passport.js')(passport, data.user, data.hashedURL) ) does not fix the problem.

Below is what I think are the relevant portions. I can post more if need be. Error point is indicated by an arrow in passport.js module below.
Thanks so much in advance for any light you can shed!

I have an abstract class:

I was building another larger app and at some point I needed to dynamically change images and my app crashed. So, to test functionality I made another really simple app that just displays a picture with code:

I am still relatively new to all this, but I am trying to access Wikipedia's API in order to retrieve the value of "extract" and to append the text to an html element. The issue is that "pages" will change depending on user input. Is there a way to access the info given the the random number in the JSON response? *Edit- I am using Jquery/Javascript. this was the API request I sent: https://en.wikipedia.org/w/api.php?format=json&action=query&prop=extracts&exintro&explaintext&redirects=1&titles=Pug
