# Prisma nested export/import example
Tried to recreate Prisma's export/import losing relations case. Does not happen
with this setup.
## Create mock nested records
1. Open http://localhost:4469
2. Create record:
```gql
mutation {
createUser(
data:{
name: "john",
posts: {
create: [
{
name: "post1",
links: {
create: [
{
url: "link1"
}
]
}
}
]
}
}
) {
id
}
}
```
## Check that nested relations are there
1. Open http://localhost:4469
2. Query:
```gql
{
users {
id
posts {
id
links {
id
}
}
}
}
```
## Export
```
prisma export
```
## Clean database before re-import
1. Open http://localhost:4469
2. Clean with multiple mutations in this order:
```gql
mutation {
deleteManyLinks {
count
}
}
mutation {
deleteManyPosts {
count
}
}
mutation {
deleteManyUsers {
count
}
}
```
## Import
```
prisma import --data export-XXX.zip
```
In my case, after an import is done - all relations are in place.
