I'm adding a list called 'tourlocation' to my Keystone 5 project. In my mongo database my tourlocations collection has an object called 'coordinates', with two values: 'lat' and 'long'. Example:
"coordinates" : {
"lat" : 53.343761,
"long" : -6.24953
},
In the previous version of keystone, I could define my tourlocation list coordinates object like this:
coordinates: {
lat: {
type: Number,
noedit: true
},
long: {
type: Number,
noedit: true
}
Now unfortunately, when I try to define the list this way it gives the error: The 'tourlocation.coordinates' field doesn't specify a valid type. (tourlocation.coordinates.type is undefined)'
Is there any way to represent objects in keystone 5?
#Alex Hughes I believe your error says "type" which you may need to add it like this
keystone.createList('User', {
fields: {
name: { type: Text }, // Look at the type "Text" even in the MongoDB you can choose the type but it will be better to choose it here from the beginning.
email: { type: Text },
},
});
Note that noedit: true is not supported in version 5 of KeystoneJS.

I have a MEAN-Stack setup in which i have Devices and Servicecases saved in the MongoDB-Database.
Devices can be the content of a Servicecase
If a new Case should be created, my Frontend will deliver the following form data:
content: [
{
"device": 012345678909876,
"errorDesc": "lorem"
},
{
"device": 012345678909876,
"errorDesc": "ipsum"
}
]
There could be a device document with the submitted device number in the Database. If yes, the received doc should be populated with its ObjectId to look like this:
content: [
{
device: { type: Schema.Types.ObjectId, ref: 'Device' },
errorDesc: String
},
...
]
If not, it should stay as it is
I could iterate through each device of the array and use the findOne() query and, if a doc was found, replace it, but is there a more efficient way to use the populate() transformation?
I have followed the doc for the ReferenceArrayInput (https://marmelab.com/react-admin/Inputs.html#common-input-props) but it does not seem to be working with relationship fields.
For example, I have this many-to-many relation for my Users (serialized version) :
Coming from (raw response from my API):
I have setup the ReferenceArrayInput as followed :
<ReferenceArrayInput source="profiles" reference="profiles" >
<SelectArrayInput optionText="label" />
</ReferenceArrayInput>
I think it's making the appropriate calls :
But here is my result :
Any idea what I'm doing wrong ?
Thanks in advance for your help !
On docs, ReferenceArrayInput is said to expect a source prop pointing to an array os ids, array of primitive types, and not array of objects with id. Looks like you are already transforming your raw response from api, so if you could transform a bit more, mapping [{id}] to [id], it could work.
If other parts of your app expects profiles to be an array of objects, just create a new object entry like profilesIds or _profiles.
As gstvg said, ReferenceArrayInput expects an array of primitive type, not array of objects.
If your current record is like below:
{
"id": 1,
"tags": [
{ id: 'programming', name: 'Programming' },
{ id: 'lifestyle', name: 'Lifestyle' }
]
}
And you have a resource /tags, which returns all tags like:
[
{ id: 'programming', name: 'Programming' },
{ id: 'lifestyle', name: 'Lifestyle' },
{ id: 'photography', name: 'Photography' }
]
Then you can do something like this (it will select the tags of current record)
<ReferenceArrayInput
reference="tags"
source="tags"
parse={(value) => value && value.map((v) => ({ id: v }))}
format={(value) => value && value.map((v) => v.id)}
>
<AutocompleteArrayInput />
</ReferenceArrayInput>
Request Json Looks like the below :-
{
"eNumber": 8506493,
"details": [
{
"id":12345,
"name": xyz123
}
]
}
As part of requirement, I need to check the "details" array that either "id" or "name" field must present. if "id" field is present, "name" is non-mandatory. if "name" field is present, "id" is non-mandatory. Throws error if not met.
I tried few options using filter the details array and check the size of the filtered array in the validation component. It does not seems to be working well. if anyone has got better solutions.please share it here.
This example code will return true or false if it passes your condition
%dw 2.0
import * from dw::core::Arrays
output application/json
---
payload.details every ((item) -> item.id? or item.name?)
The function I'm using is every that checks that all elements in an array passes the given criteria.
Later you can use a choice and a use the raise error or you can use the fail dw function with an if else.
You can restrict it at RAML level.
Sample RAML -
#%RAML 1.0
title: api
types:
test1:
type: object
properties:
id:
type: string
example: 123a
test2:
type: object
properties:
name:
type: string
example: xyz124
test3:
type: object
properties:
enumber:
type: string
example: 8506493a
details :
type: [test1 | test2]
/test:
post:
body:
application/json:
type: test3
I resolve most of my problem only few left out of which this one is preventing me to submit the form. I am using Nativescript + vue and without Typescript. how to display the Valueproviders with array list? Here is the code
https://play.nativescript.org/?template=play-vue&id=2oWObE
There was the problem with your data type. As per the documentation Array should have key and label properties. But still if you want id and name then you should try like below.
'valuesProvider': {
key: 'id',
label: 'name',
items: [
{ id: 1121, name: 'Shanghai' },
{ id: 3651, name: 'Lagos' },
{ id: 5213, name: 'Moscow' },
{ id: 6214, name: 'São Paulo' },
{ id: 6985, name: 'Sydney' }
]
};
https://docs.nativescript.org/vuejs/ns-ui/DataForm/dataform-editors-providers
Anyway, I tried that and that was not working for me either then searched for it and relaised that there is an open feature request to support the valuesProvider for picker from JSON metadata. You can vote to support the same feature.

Solution
Just get you cityList out of vue data and map your data

Basically, without knowing before hand what the resulting structure of a query might be, I'd like to query the database, and return a structure like this (json-y)
// Rows
[
// Row 1
[
{ ColumnName: "id", Value: 1, Type: int },
{ ColumnName: "name", Value: "batman", Type: string },
...
],
// Row 2
[
{ ColumnName: "id", Value: 2, Type: int },
{ ColumnName: "name", Value: "superman", Type: string },
...
]
]
Is there a way to get the Type for a Column using package database/sql in golang?
I'm suspecting that what I want to do is
make an array of interface{} the size of Column(),
then for each column determine it's type,
then fill the array with a pointer to that type,
and then pass the array to Scan()
Which is a little like this code example from sqlx, but without first knowing the Struct that the data would be populating.
You should be able to do it this way:
func printRows(rows *sql.Rows){
colTypes, err := rows.ColumnTypes()
for _,s := range colTypes {
log.Println("cols type:", s.DatabaseTypeName());
}
}
Using database/sql? No (as far as I know).
But you can use this code for arbitrary queries. And json.Marshall() from the json package will use reflection to determine the right way to print a value, so you could have a structure like this:
type Column struct {
ColumnName string
ColumnValue interface{}
ColumnType string
}
And then use reflect.TypeOf(someVariable).String() to get the type for ColumnType.
