@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: Ok, so you have a one-to-many relation between User and Slide to save the last slide a user has visited?

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: no, one-to-one. But Lesson and Slide have one-to-many

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: one-to-one means that one slide cannot be stored by two different users

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: oh, yes I mean one-to-many

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: Is there a reason you are storing this information of the current slide on the server rather on the client?

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: Yes, I need other users know what he or she is looking at

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: So having the currentSlide I'm going up the schema to fetch current lesson and down again to fetch the list of slides in the current lesson.

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: I see! You can make that more efficient if you use two different queries

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: One to query the id of the current slide

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: and then one that queries the lesson of that slide and all other slides

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: Or you do this:

currentSlide{
		id
		lesson{
			id
			slides {
              id
            }
		}
	}

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: there shouldn't be a significant performance drawback

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: So do I understand correctly that going from children to parents and going back to their children doesn't stress the DB?

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: There's a small overhead involved, but we're `JOIN`ing the DB tables so it's really only a small overhead.

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: Great that's exactly what I wanted to know! Thank you! Just one more question you said I can do two queries. Can I batch them together somehow so I wouldn't wait for the response before sending the second one?

@nilan commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: No, that would be two separate queries

@alex_ye commented on @alex_ye’s file https://prisma.slack.com/files/U3WSHAM39/F46B1EW4A/Hi__How_does_this_query_affect_performance_.js: Got it, thank you, Nilan!

Thanks @nilan! 👋 Hello everyone, I’m Josh Dzielak, a Developer Advocate at Algolia. If you have any questions about Algolia or how to connect your graphcool apps don’t hesitate to ask.

Awesome to have you here @dzello 🙌

Same goes for @ron @giga @eli and @flesch 🙂

Is there a way to batch upload data? Example: Uploading a CSV list of cities. Or will I have to write a script?

Subscriptions are coming to the spec soon! https://dev-blog.apollodata.com/the-next-step-for-realtime-data-in-graphql-b564b72eb07b?source=linkShare-803918030a60-1487291109

Welcome to our community @puls @vacom @atoumbre @jdinh @cnoter and @mphilpot 👋 Please let me know if I can help you getting up and running 🙂

Hi. Does someone know how to build offline first mobile or web apps with Graphcool backends?

Hi! i want to update a node related to another node. it could be Address node nested into Contact node... can i update it using the updateContact mutation? i thought so but i'm having troubles

How does graphcool dynamically create the

filter

for a node? Or is it some secret sauce 🙂

@zebapy secret sauce ;)

Hey guys, I'm trying to use recompose as mentioned in Sashko's recent blog post. Here's my code:

export default compose(
  withRouter,
  graphql(FeedQuery, feedQueryOptions),
  graphql(userQuery, { options: { forceFetch: true }}),
)(Module)

if you look at the two

graphql()

lines, those are both the

data

portion of my compose. It seems like only the second one gets composed on my component. I'm guessing because props.data gets overwritten? What do you do when you have multiple datas? One option I can think of is renaming the second one so it doesn't go into props.data, but not sure if that's the best/common practice

Hey guys, seems like a small UI inconvenience in the PlayGround. When I click on "DOCS", not everything is visible, and I'm not able to pull it any further to see the text (on a macbook retina 13"). My only way is to zoom out the browser to 50% to be able to check the docs:
