QUESTION
Right now I have a flatlist that contains a bunch of firebase objects (books), when one of the book are clicked, I want to return a page with more data about that specific book. Right now each book it an object, where title is one of the values, this is what is shown on the flatlist. I want to be able to show all of the other object attributes when the new detailed page is opened. If there is a better way of doing this, let me know but this is the logic that I was trying to go with.
...ANSWER
Answered 2020-Aug-25 at 03:54Since you already have access to the required object
that is to be passed to the next screen, it's very easy, you can pass it along with the navigation object as a route
param.
It's always good to isolate the prop
functions to separate functions to avoid unnecessary re-render of the component.
Here is an example.
QUESTION
Error from server: Get https://10.128.15.203:10250/containerLogs/default/postgres-54db6bdb8b-cmrsb/postgres: EOF
How could I solve this issue ? And what can be reason . I've used this tutrial for configuring all stuff (https://severalnines.com/database-blog/using-kubernetes-deploy-postgresql). If you need more info , pls let me know !
kubectl describe pods postgres-54db6bdb8b-cmrsb
...ANSWER
Answered 2019-Dec-17 at 11:09The issue is here: error while creating mount source path '/mnt/data': mkdir /mnt/data: read-only file system.
You need to make sure postgres-pv-claim
is writable. You need to recreate the pv and pv claim with RWO access (you must have mistyped it to RO instead which is why you ran into the issue) then try to deploy postgres pod which should fix the issue.
Provisioning persistent volume in GKE you don't need to create PersistentVolume objects they are dynamically created by GKE. So solve the Warning FailedScheduling 69s (x10 over 7m35s)
issue
- remove
storageClassName
property from your pvc and - delete pv
which should fix the issue. Please see below revised postgres-storage.yaml
.
QUESTION
I don't know why the handleScroll only executes once, not when i keep scrolling up and down. And I need to somehow get the element's height but im not sure how other than documentElement. The function needs to turn a true/false so that I can do a setState and add/change a class in my heroGallery div for a css animation.
...ANSWER
Answered 2019-May-01 at 03:36It is because you are invoking the method in your addEventListener
.

Change your componentDidMount
function to this.
