Load relationships on demand about plugin-graphql

[phortx]

I could imagine, that the fetch() method accepts a include param with a list of relationships to eager load for that request. Could be useful.

Also consider relations och relations.

For instance, MusicUsageAreasModel -> hasMany(PriceListsModel) -> hasMany(PricePriceRowsModel)

You might want to to eager loadpriceRows or perhaps not.

await MusicUsageAreasModel.fetch({ include: priceLists, priceLists.priceRows] })

How to combine queries to API?

Let's say we have Posts, Authors, and Comments.

Currently I have to do 3 queries:

Posts.fetch()
Comments.fetch()
Users.fetch()

Of course that is not optimal.

Plus when I bind fetch() to created(), every time I re-navigate to the page, the server is queried 4 times, once again.

I imagine I have to write a judgment to check if the store has already been populated before calling the query.

Yet, because I read that the package caches the queries, I wonder if there is a built-in way of doing this.

@gotexis you can use eager loading to achieve that. See the docs. This way you could just fetch the Post and all related records are fetched within one query.

@phortx that's done on the model level, not on the query level (via fetch method). Would be great to control it more finely, on the fetch level.

@dmitry Absolutely!
