In GraphQL mutations is the operation type for when you need to modify data. Super Graph supports the `insert`, `update`, `upsert` and `delete`. You can also do complex nested inserts and updates.
|
||||
|
||||
When using mutations the data must be passed as variables since Super Graphs compiles the query into an prepared statement in the database for maximum speed. Prepared statements are are functions in your code when called they accept arguments and your variables are passed in as those arguments.

### Using variables
|
||||
## Nested Mutations
|
||||
|
||||
Often you will need to create or update multiple related items at the same time. This can be done using nested mutations. For example you might need to create a product and assign it to a user, or create a user and his products at the same time. You just have to use simple json to define you mutation and Super Graph takes care of the rest.
|
||||
|
||||
### Nested Insert
|
||||
|
||||
Create a product item first and then assign it to a user
|
||||
|
||||
```json
|
||||
{
|
||||
"data": {
|
||||
"name": "Apple",
|
||||
"price": 1.25,
|
||||
"created_at": "now",
|
||||
"updated_at": "now",
|
||||
"user": {
|
||||
"connect": { "id": 5 }
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```graphql
|
||||
mutation {
|
||||
product(insert: $data) {
|
||||
id
|
||||
name
|
||||
user {
|
||||
id
|
||||
full_name
|
||||
email
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Or it's reverse, create the user first and then his product
|
||||
|
||||
```json
|
||||
{
|
||||
"data": {
|
||||
"email": "thedude@rug.com",
|
||||
"full_name": "The Dude",
|
||||
"created_at": "now",
|
||||
"updated_at": "now",
|
||||
"product": {
|
||||
"name": "Apple",
|
||||
"price": 1.25,
|
||||
"created_at": "now",
|
||||
"updated_at": "now"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```graphql
|
||||
mutation {
|
||||
user(insert: $data) {
|
||||
id
|
||||
full_name
|
||||
email
|
||||
product {
|
||||
id
|
||||
name
|
||||
price
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Nested Updates
|
||||
|
||||
Update a product item first and then assign it to a user
|
||||
|
||||
```json
|
||||
{
|
||||
"data": {
|
||||
"name": "Apple",
|
||||
"price": 1.25,
|
||||
"user": {
|
||||
"connect": { "id": 5 }
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```graphql
|
||||
mutation {
|
||||
product(update: $data, id: 5) {
|
||||
id
|
||||
name
|
||||
user {
|
||||
id
|
||||
full_name
|
||||
email
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Or it's reverse, update a user first and then his product
|
||||
|
||||
```json
|
||||
{
|
||||
"data": {
|
||||
"email": "newemail@me.com",
|
||||
"full_name": "The Dude",
|
||||
"product": {
|
||||
"name": "Banana",
|
||||
"price": 1.25,
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
```graphql
|
||||
mutation {
|
||||
user(update: $data, id: 1) {
|
||||
id
|
||||
full_name
|
||||
email
|
||||
product {
|
||||
id
|
||||
name
|
||||
price
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Using variables
|
||||
|
||||
Variables (`$product_id`) and their values (`"product_id": 5`) can be passed along side the GraphQL query. Using variables makes for better client side code as well as improved server side SQL query caching. The build-in web-ui also supports setting variables. Not having to manipulate your GraphQL query string to insert values into it makes for cleaner
|
||||
and better client side code.
