url-slug | Slug generator with less than 1 KB | Internationalization library

I need to ask - I've got a /users endpoint and I want to add tasks to user, just like that: /users/:username/tasks. Should I create another model and route? I don't know how to add an ID to an array in Mongoose model and add a slug with mongoose-url-slugs.

I want it to be RESTful as much as I can. So this: /users/:username/tasks or /tasks/:username? If first, I need to know how to add ID to tasks in that model:

The question is from freecodecamp Link

Fill in the urlSlug function so it converts a string title and returns the hyphenated version for the URL. You can use any of the methods covered in this section, and don't use replace. Here are the requirements:

The input is a string with spaces and title-cased words

The output is a string with the spaces between words replaced by a hyphen (-)

The output should be all lower-cased letters

The output should not have any spaces

$lookup in aggregation working properly in mongo shell command, but while tried by using mongoose node, then getting empty array as response. I have two collection, and tried to get all records from one collection along with matched record of another collection as part of response objects

I am making classifieds ad web site. In that I need to load one ad without URL parameters. I did it with URL parameters successfully. Now I want to remove parameters from the URL. I stored URL-slug which is constructed saving time of ad in database. In ad page load time there are many functions called. Those functions asks data from database according to URL parameter value. I tried with htaccess rules. But rest of page and details load as before. But ajax functions called data which are supposed to display on div tags not working. They show whole page inside those divs.

I tried following htaccess rules so far.

I have a json array of the form:

I'm trying to find a way to redirect 404 and 503 errors (and similar types) to a page via .HTACCESS, but with some added values.

Example - if a person lands on a 404 error page, the link would normally look like: https://www.yourdomain.com/pages/404

How would you get it like:
https://www.yourdomain.com/pages/404?submit=error&msg=3
(in POST or alternatively GET data)

This question translates part of what I'm looking for, but not quite (as the answer is clearly 'No'): Can I use .htaccess to convert a url slug to a POST request?

Can this be done, and are there any security implications if it was done?

This is in error_page.php:

I am having trouble iterating through some JSON data that I managed to import into my Django Wagtail project. I want to list travel advisories on a website that are pulled in from here: http://data.international.gc.ca/travel-voyage/index-updated.json

I was able to do this in my model like so:

So firstly, I checked the relevant question but since I'm not using the same middleware, I don't think it helped me. I have a regular form and while it successfully goes through req.body and I can print all the form values. However the problems are when I try to create a new object because when I print it, it doesn't have the correct fields that I assigned it...? And secondly, when I try to save it, it doesn't show up in the Db when I check via Terminal. I have successfully run Mongod and am connected to the correct Db and collection so I'm confused. Any help would be greatly appreciated!

Here is the relevant code
