restaurants | Restaurants - Isomorphic Flux Application | Frontend Framework library

I have recently upgraded my flutter to the latest version and I am getting all the null safety errors.

Trying to pick out single restaurant elements under the All Restaurants category on this page. https://www.foodpanda.sg/restaurants/new?lat=1.2915902&lng=103.8379066&vertical=restaurants

All li elements have a different class name. The only working xpath, I have been able to figure out is this one.

//ul[@class="vendor-list"]//li[3]

I cannot figure out how to increase this number and get all the restaurants, which is complicated by the fact that there is an infinite scroll as well.

I have these code where i found online.

I am trying to scrape some contents on a website. I keep getting this error, 'NoneType' object has no attribute 'text' but I don't know how to fix this.

I noticed that the error has to do with this line tr.find("a", class_="sc-dakcWe sc-liNYZW cPIBpC").text.replace("\n", " ") but I have been stucked on how to fix it. After removing the .text.replace("\n", " ") part from it, I get the response as None. I realise my issue is how to get the correct selector for it, what could I change this tr.find("a", class_="sc-dakcWe sc-liNYZW cPIBpC") to that would give me the correct restaurant_name.

I am using the zomato restaurant and an example url for this is https://www.zomato.com/kanpur/top-restaurants

I have an issue while trying to scrape a website. I have tried a couple of methods to get the restaurant_name, cuisine, address and star ratings but I keep getting the error 'NoneType' object has no attribute 'text' which shows that this tr.find("a", class_="sc-dakcWe sc-liNYZW cPIBpC") returns None for all the iterations.

I want to get all the restaurants that are near the user's current location (10KM in range).

I have a users table user(Id, Name, Address), here the address is a lat, long string. e.g. 20,21.

2nd table is restaurant(Id, Name, Address), and the format for address is the same as above.

On the front-end I get the current location of the user, and send to the API, and in the API I have a function calling below query from MySQL:

Here my server side code

hello i have a script using Python and Selenium, and I don't understand why this can't retrieve the JS part of the website (the same script works perfectly fine on my other machine):

I am trying to implement infinite scrolling for documents stored in a MongoDB collection. Every document is a restaurant that has a numeric field rating, so I am using the rating field for sorting and showing restaurants with the highest rating first.

The problem is that the collection of the restaurants is not static. The ratings of the restaurants change in real time, therefore the order of the restaurants in the collection changes constantly. As a result, although I formally have the sorting key, it does not make much sense.

I am thinking of 2 solutions of the problem:

1. Accept that the order of the restaurants may change slightly while someone is doing the infinite scrolling. Make the front end responsible for getting rid of possible duplicates. Accept that some of the restaurants may not appear during a scrolling at all. But that looks more like working around the problem instead of solving it.
2. Only perform infinite scrolling against a static copy of the collection of restaurants. Update the static copy periodically (e.g., once a day) with the rating updates. But this approach seems overengineered. Also, what happens with the infinite scrolling at the moment when the static copy of the restaurants gets updated with the new ratings? Such scrolling will be broken as well because the problem with the changing order is still here, the order just does not change that frequently.

I am sure I am far not the first one who have faced this problem. After all, there are a lot of examples of infinite scrolling implementations out there, like Facebook or Instagram feeds. At the same time, all the articles I have read so far seem too superficial and covering only cases with infinite scrolling through static collections.

What is the right approach to deal with infinite scrolling for a collection that may change its order any time?

Thank you.
