QUESTION

loading redux items into state from a direct link

Asked 2021-Jun-14 at 04:40

This is sort of a "best practices" question, since I'm not clear on the right way to handle this case.

The situation is that I have a bookstore app with a list of books that exists as state.bookstore.books. When the visitor loads the index page of the bookstore, a thunk action is dispatched that loads all the book objects in the user's collection into the state.bookstore.books array.

From the bookstore page, a user can click on an individual book, and a new page is loaded that pulls the book item from the state books array and displays the details.

My problem is that if a user directly visits the book detail link (eg. "mysite.com/book/123") without first going through the homepage, the state.bookstore.books array is empty, and the page has no data to display.

My question is what is the "right" way to do this? Would I dispatch the loadBookstore action to populate the state anytime the app is initialized? Would I create a new redux feature for book? Would I ignore looking up the book in the state, and just grab the specific book record from the server?

I am assuming that I'm doing it wrong / implementing an anti-pattern because selectors are not built to take parameters, so it seems like since there's no easy way to grab book 123 from the store, then I shouldn't be doing it this way.

Let's say we have 2 components

BooksHome for /books/
SingleBook for /books/:id

So when the user visits /books/ route, fire a thunk fetchBooks(..) which loads books and saves them in state.bookstore.books and display those books in BooksHome

And when the user visits /books/:id route, fire a thunk fetchSingleBook(..) which will find book item with :id in state.bookstore.books if that's present return it and display it in SingleBook and if it's not there, fetch it, add it to state.bookstore.books and return it and display it in SingleBook.

Explanation:

When the user visits /books/123 right away, state.bookstore.books is [] so no item is found, so we'll fetch it, store it and display it.

When the user visits /books/ (data fetched and stored) and then visits /books/123, state.bookstore.books is having an item with id:123 so the item is found, so we'll get it from state.bookstore.books and display it.

Must do things:

fetchBooks must be dispatched in BooksHome but not in App
Same way fetchSingleBook must be dispatched in SingleBook

Things optimised with this approach:

We need not fetch all books for displaying a single book.
We need not re-fetch book's data when it is already available in state.bookstore.books

Hope this helps🤝

Due to the grouping you already have, count($elems) will have the right value in the return clause.

I think you original use of the let $sep is causing problems, the grouping count($elems) I suggested works fine for me at https://xqueryfiddle.liberty-development.net/bFDbxm7 where I have moved the $sep to a declared variable.

Spring Boot: Create Custom Jsp Tag - Unable to find taglib

Asked 2021-Apr-27 at 20:50

I want to add a custom Jsp tag to Spring boot. But I can't figure out project structure/URI for the taglib definition

I tried searching for solutions, but they are too ... deprecated. Using web.xml stuff, or really old folder structure which spring boot doesn't support by default.

While trying to load jsp page o get this error org.apache.jasper.JasperException: Unable to find taglib [ex] for URI: [/customTags.tld]

This is my current folder structure

ANSWER

Answered 2021-Apr-27 at 20:50

So project structure was good. The reason why it couldnt find taglib is that uri is not a filepath its a domain (you can make it up)

C++/WinRT XAML controls bind to a property

Asked 2021-Apr-25 at 12:27

I am attempting to expand the Bookstore example by introducing an other ViewModel to have Sections within the book store. I my case I am calling it 'Library'. I am having difficulty in getting the books added to display in a second ListView. In MainPage in addition to the MainViewModel (which now displays the sections) I have added SubModelView to return the current Section. In my Xaml code I have constructed a second ListView with the code to display the books but it is not working. Can anybody advise what I am doing incorrectly. I have included a SubModelView in MainPage to access the current Section in which the books are being created and used this in the Xaml code.

Based on your description and code, I assume that you want to add a layer called Section to your Library app. Input a Section name and add multiple books into the added Section with TextBox controls and Button controls.
