You can do it with the $event parameter. Make sure to compare your values safely.

If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.

You can use the trim function to compare your value safely: c.state.trim() == val.trim()

After some further consultation with my teammates, I found a solution. Seems you have to create a dataSource and in the params you need to just send the following {page: dataSource._page - 1, size: dataSource._pageSize}

You can create nested serializer as

A few little things need to be changed in your code. Below is your code with my corrections. Explanations after the code.

If you want to pull out the entire top row per user, you cannot use aggregation only. Instead, you need some filtering.

If you are running MySQL 8.0, you can use row_number():

On your side there's nothing you can do until pagination is implemented on API side. Depending on the way it's implemented, you will probably make requests to API sending params like offset, page, limit- these are the most common params' names saying how many elements should API return. But if that's 3rd party provider and their docs are not saying anything about such possibility, you're most likely won't be able to do what you want

Please try query below:

Edited after edition in question: when you say self.authors_list = ... the class variable is not getting updated, instead a new object variable gets created, and it's available only to that class instance. In the case of quotes, you are doing any assignment, and instead, you do an append which gets reflected in the class variable quotes.

When you did QuotesToScrape.authors_list instead, you changed the class variable, and this get's reflected in other object instances you create afterwards.

Try understand your case with this example:

The only problem here is when you create an "Adapter" you are assigning to a local val myAdapter so when you are trying to notifydatachange, class member is still found uninitialized.

Solution

change :

val myAdapter = ArrayAdapter(this, android.R.layout.simple_expandable_list_item_1, defns)

to

myAdapter = ArrayAdapter(this, android.R.layout.simple_expandable_list_item_1, defns)
