is it possible this clear and important feture?

Hi,
You can use custom fields to add fields to core entities. It is also possible to use a graphql resolver to extend entities.

Hi @michaelbromley ,
I would like to extend from Vendure to create other features.
In my case, I want to create blogs that are related to products. Can I do it and how to start?
Could you give me some reference docs?

Thanks in advance.

Best Regard,
Ly Tran

Hi,
Start by getting an understanding of how plugins work in vendure: https://www.vendure.io/docs/plugins/

And to add a new feature like a blog, you can look at this example of adding a new entity: https://www.vendure.io/docs/plugins/plugin-examples/defining-db-entity/

Thanks for your response.

Hi again
what should i do with many2many and many2one and one2one rel
if custom field is a entity

https://www.vendure.io/docs/developer-guide/customizing-models/#relations
It is possible to set up custom fields which hold references to other entities using the 'relation' type

@michaelbromley
this error occurred

The GraphQL type "mypluginEntetyX" specified by the Product.x custom field does not exist

where should i define graphql type for my entities??

[lusicsmusics1]

graphQLType?: string: The name of the GraphQL type that corresponds to the entity. Can be omitted if it is the same, which is usually the case.

[lusicsmusics1]

The GraphQL type "X" specified by the X custom field does not exist
what should i need to reform this error
the graphql is very boring and repeated writing code without need

[michaelbromley]

You can define a new type like this:

import gql from 'graphql-tag';

const schemaExtensions = gql`
  type MyNewType {
    name: String!
    ... etc
  }
`;

you can see an example of this here: https://github.com/vendure-ecommerce/real-world-vendure/blob/master/src/plugins/reviews/graphql/api-extensions.ts

[lusicsmusics1]

import gql from 'graphql-tag';

const schemaExtensions = gql`
  type MyNewType {
    name: String!
    ... etc
  }
`;

in /real-world-vendure/blob/master/src/plugins/reviews/graphql/api-extensions.ts
import is from this:
import { gql } from 'apollo-server-core';

but you say
import gql from 'graphql-tag';
🤔🤔

[michaelbromley]

ok, I was doing it from memory. I think either import will work.

[lusicsmusics1]

there is no way we automate defining graphql type????
why we have this codes:
