Find is undefined...

[to175]

Hello,
I have an error when I try to find element by vi_part with db.find()
Can you help me please ?

The code to call find : https://gist.github.com/to175/69e2fc3b647c7408d18a43d1fdb37964

My database : https://gist.github.com/to175/f4685e4124b749c864874fde37f43474

The error :

undefined is not a function (evaluating 'local_database_models.find({
selector: {
vi_part: "SCBPX"
}
})')

install pouchdb-find and add this to your code :

import PouchDB from 'pouchdb-react-native'
import find from 'pouchdb-find';

PouchDB.plugin(find)

Thanks but why does the pouchdb-find page sais :

The pouchdb-find plugin is being incorporated into PouchDB itself.

The pouchdb-find is not only for react-native language ? Why it is not in pouchdb-react-native ?

[paulbx81]

Good question ^^
anyway my .find is too long, 2 or 3 seconds.. and it's instant on web browser

Thanks you,

What do you mean by your find is too long ? And why are you talking about web browser ? 😛

[paulbx81]

On my react-native app my .find() take 5 seconds
if i try this .find on webBrowser (with the same database couchDB) the .find take 250ms

(sorry my english is bad i'm french)

Okay let's talk en français alors. Le .find() de ton application tu l'utilises grâce à pouchdb-react-native ou pouchdb-find ?

Quand tu dis que tu utilises un webbrowser tu veux dire que tu utilises la même fonctione .find() mais sur une base de donnée récupérée sur internet ? Genre en faisant db = PouchDB.create('http://....') ?

Merci ! 👍

J'ai une base donnée CouchDB qui contient des données.

J'utilise poouchdb-react-native sur mon application react-native pour interroger ma base de donnée couchDB.

Lorsque je fais un .find() sur mon application react-native vers cette base de donnée, la durée du .find() prend 5 secondes.

Si je fais un .find sur une page HTML en javascript en utilisant la librairie pouchDB et en ciblant la même base de donnée CouchDB, la requête dure moins de 1 seconde.

(i ask the same couchDb database for the both .find() )

Merci pour les détails 😄

J'ai du mal à saisir les différences. Pour mon cas (base PouchDB locale sur mon app react-native), je suis obligé d'utiliser le .find() de react native find ? ça va durer longtemps la requête tu penses ?
