QUESTION
I've a Tabview
along with a list of azlist scrollable bar
. When scrolling through the azlist bar
, the TabView
moves along easily trying to slide to another Tab
. I want the TabView
to be stay put during scrolling of the azlist scrollable bar
. Is there a way to prevent this behavior for TabView
? I've tried declare a CustomScrollPhysic
but it just didn't work the way I want it to be.
Below are attached gif & code for it.
import this in pubspec
...ANSWER
Answered 2022-Mar-11 at 05:03I have a very similar page: two tabs both containing alphabet lists and the scrolling are working well.
I do not have a CustomScrollPhysics on my widgets, but use a TabController.
QUESTION
I have a problem with the code that I wrote. I have some test cases that have the results for the same. When I run these TC on my laptop the result is as expected, but when I upload code to my class grader only the first one doesn't work and says that the algorithm is not good or that there is some infinite loop. I think that the code is good; maybe I am wrong. What do you think?
Test Case 1:
...ANSWER
Answered 2022-Jan-08 at 21:19At least these problems:
Parsing is dodgy
Input is line orientated, but "%*c%*c%*c%*c%*c%*c%*c %[^ ] %[^:]%*c %[^\n]"
readily can go pass the line.
The best way to read a line from stdin
is fgets()
, then parse.
Use width limits. Consider using " %n"
to detect successful end of parsing.

I'm currently using sttp version 3.3.14 with tapir version 0.18.0-M15 and I'm having trouble with the Schemas of certain case classes. More specifically, case classes that contain type aliases.
Here is a simple custom Codec for Either:

QUESTION
The Tapir documentation states that it supports decoding sealed traits: https://tapir.softwaremill.com/en/latest/endpoint/customtypes.html#sealed-traits-coproducts
However, when I try to do so using this code, I get the following error:
...ANSWER
Answered 2020-Dec-11 at 12:59The decoding is delegated to Circe. What is described in the documentation is only derivation of Schema
s - which are necessary for documentation.
Hence, I'd be looking for the cause of the error by checking if you have the proper Decoder
in scope, and checking what happens if you try to decode an example value directly using circe.
QUESTION
Im defining endpoints using tapir however i get the following compilation error.
...[info] Compiling 3 Scala sources to /endpoints/target/scala-2.13/classes ... [error] Error while emitting/endpoints/Session$ [error] Method too large: endpoints/Session$. ()V [error] one error found [error] (endpoints / Compile / compileIncremental) Compilation failed [error] Total time: 26 s, completed 12-Mar-2020 15:29:54
ANSWER
Answered 2020-Mar-19 at 12:06It looks like because i had so many endpoints with many statusMappings that it was causing the constructor to become too large.
I fixed this issue by putting manualReviewEndpoint
into its own object.
QUESTION
I am stuck at a place, I am using scala, tapir and circe.
...ANSWER
Answered 2020-Mar-16 at 19:38Tapir codec is derived from Circe's decoder and encoder.
What you see is the default way of encoding case classes by circe.
Circe provides the possibility to encode case classes the way you described with deriveUnwrappedEncoder
from circe-generic-extras. Unfortunately, it doesn't compile for SMError
(probably derivation mechanism gets confused by your abstract class hierarchy).
What you can do is just creating encoder manually:

I'm working on a project in python where I get a json from a REST API using requests and then proceed to load it into a PostgreSQL database. The json the API responds with is strctured like shown below. My main issue is concerning the nested fields, like location.lat

QUESTION
I'm a very unexperienced user of REST APIs, requests and python, so bear with me. I've managed to throw a GET request using requests via python towards this REST API that was developed with Postman. I get results fine, but only for the first page (only 50 items). I know that all I need to do in order to get more results is adding '?page=2' and so on to the URL, but somehow I couldn't manage the loop so far. It appears to me that this API doesn't have the "nextUrl" or total number of pages features, so I'm a bit lost. This is what I have so far:
...ANSWER
Answered 2020-Feb-08 at 02:19Since we don't know the number of pages( the available projectid
), you can use try & except
