I have a json with a param Ids, and For each Id I would like to create a Tree List and bind the data with the given ID. I was wondering what are the ways to achieve it. Especially the columns are identical but how to provide the configuration settings for each dynamically created Tree Lists.
{
"id":"1",
"data": "hello",
"status": "inProgress"
},
{
"id":"1",
"data": "hello",
"status": "inProgress"
},
{
"id":"1",
"data": "hello",
"status": "inProgress"
},
{
"id":"2",
"data": "hello",
"status": "inProgress"
},
{
"id":"2",
"data": "hello",
"status": "inProgress"
}
Here all the Id 1 data will be part of one TreeList and the ones with Id 2, will be part of another TreeList.
At the end have to re-Model my Data to have Parent Child Ids.

I'm trying to filter Directus CMS data set through URL parameters.
This is a sample data set. I can successfully filter data set by single parameter.
{
"data":[
{
"id": "1",
"status": "published",
"category": "Novel",
"section": "Kids"
},
{
"id": "2",
"status": "published",
"category": "Novel",
"section": "Adults"
}
]
}
/items/books?filter[category][_eq]=Novel
gives me exactly what I expected which is 1 & 2 data records.
But I need to filter both "category" & "section" fields
/items/books?filter[category][_eq]=Novel&filter[section][_eq]=Adults
For above I receive an empty data set.
Why is this getting failed ? Where do I need to fix? Appreciate your support in advance. Thanks!
Try the following query:
/items/books?filter={"_or":[{"category":{"_eq": "Novel"}},{"section":{"_eq":"Adults"}}]}
An expanded version of the filter:
"_or": [
{
"category": {
"_eq": "Novel"
}
},
{
"section": {
"_eq": "Adults"
}
}
]

I need help on how to delete records that exist in the DB but not in array sent in a request;
My Array:
[
{ "id": "509",
"name": "Motions move great",
"body": "",
"subtopics": [
{
"title": "Tywan",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
},
{
"title": "Transportations Gracious",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
},
{
"title": "Transportation part",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
}
]
},
{
"name": "Motions kkk",
"body": "",
"subtopics": [
{
"title": "Transportations",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
}
]
}
]
Below is my implementation: where am going wrong?
#topics = #course.topics.map{|m| m.id()}
#delete= #topics
puts #delete
if Topic.where.not('id IN(?)', #topics).any?
#topics.each do |topic|
topic.destroy
end
end
it's not clear to me where, in your code, you pick the ids sent in the array you showed before... so I'm assuming like this:
objects_sent = [
{ "id": "509",
"name": "Motions move great",
"body": "",
"subtopics": [
{
"title": "Tywan",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
},
{
"title": "Transportations Gracious",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
},
{
"title": "Transportation part",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
}
]
},
{
"name": "Motions kkk",
"body": "",
"subtopics": [
{
"title": "Transportations",
"url_path": "https://ugonline.s3.amazonaws.com/resources/6ca0fd64-8214-4788-8967-b650722ac97f/WhatsApp+Audio+2021-09-24+at+13.57.34.mpeg"
}
]
}
]
since you have your array like this, the only information you need to query on database is the ids (also, assuming the id's in the array are the id's on database, otherwise it wouldn't make sense). You can get them like this:
sent_ids = objects_sent.map{|o| o['id'].to_i}
Also, it seems to me that, for the code you showed, you want to destroy them based on a specific course. There would be 2 ways to do that. First, using the relationship (I prefer like this one):
#course.topics.where.not(id: sent_ids).destroy_all
Or you can do the query directly on the Topic model, but passing the course_id param:
Topic.where(course_id: #course.id).where.not(id: sent_ids).destroy_all
ActiveRecord is smart enough to mount that query correctly in both ways. Give it a test and see which works better for you
I am writing a GraphQL resolver that retrieves all vertices by a particular edge using the following query (created returns label person):
software {
created {
name
}
}
Which would resolve to the following Gremlin Query for each software node found:
g.V().hasLabel('software').has('name', 'ripple').in('created')
This returns a result that includes all properties of the object:
{
"result": [
{
"#type": "d",
"#rid": "#24:0",
"#version": 6,
"#class": "person",
"in_knows": [
"#35:0"
],
"name": "josh",
"out_created": [
"#32:0",
"#33:0"
],
"age": 32,
"#fieldTypes": "in_knows=g,out_created=g"
}
],
"dbStats": {
...
}
}
I realize that this will fall foul on GraphQL's N+1 query so i'm trying to batch queries together using a Dataloader pattern. (i'm also hoping to do property selections, so i'm not asking the database to return too much info)
So i'm trying to craft a query like so:
g.V().union(
__.hasLabel('software').has('name', 'ripple').
project('parent', 'child').by('id').
by(__.in('created').fold()),
__.hasLabel('software').has('name', 'lop').
project('parent', 'child').by('id').
by(__.in('created').fold())
)
But this results in the following where the props are missing and it just includes the id of the vertices I want:
{
"result": [
{
"parent": "ripple",
"child": [
"#24:0"
]
},
{
"parent": "lop",
"child": [
"#22:0",
"#23:0",
"#24:0"
]
}
],
"dbStats": {
...
}
}
My Question is, how can I have the Gremlin query return all of the props for the found vertices and none of the other props? Should I even been doing batching this way?
For anyone else reading, the query I was trying to write wouldn't work because the TraversalSet created in the .by(_.in('created') can't be cast from a List to an ElementMap as the stream cardinality wouldn't be enforced. (You can only have one record per row, I think?)
My working query would be to duplicate the keys for each row and specify the props needed (the query below is ok for gremlin 3.3 as used in ODB, otherwise if you've got < gremlin 3.4 replace the last by step with be(elementMap('name', 'age')):
g.V().union(
__.hasLabel('software').has('name', 'ripple').
as('parent').
in('created').as('child').
select('parent', 'child').
by(values('name')).
by(properties('id', 'name', 'age').
group().by(__.key()).
by(__.value())),
__.hasLabel('software').has('name', 'lop').
as('parent').
in('created').as('child').
select('parent', 'child').
by(values('name')).
by(properties('id', 'name', 'age').
group().by(__.key()).
by(__.value()))
)
So that you get a result like this:
{"data": [
{
"parent": "ripple",
"child": {
"id": 5717,
"name": "josh",
"age": 32
}
},
{
"parent": "lop",
"child": {
"id": 5709,
"name": "peter",
"age": 35
}
},
{
"parent": "lop",
"child": {
"id": 5713,
"name": "marko",
"age": 29
}
},
{
"parent": "lop",
"child": {
"id": 5717,
"name": "josh",
"age": 32
}
}
]
}
Which would allow you to create a lookup where you concat all results for "lop" and "ripple" into arrays.
Assuming i have a class User and a class Profile
The profile class has a field called "sex" and a field called "user" which is a pointer to user class.
If i get the profile endpoint with : https://myapi.back4app.io/classes/Profile i can get the Profile object:
{
"results": [
{
"objectId": "sIE6lOZP7R",
"user": {
"__type": "Pointer",
"className": "_User",
"objectId": "asP3EFYSR4"
},
"sex": "male",
"createdAt": "2020-05-25T17:15:49.324Z",
"updatedAt": "2020-05-25T17:15:49.324Z"
}
]
}
and if i want to include the user of this profile, i can include with: https://myapi.back4app.io/classes/Perfil?include=user so i get:
{
"results": [
{
"objectId": "sIE6lOZP7R",
"user": {
"objectId": "asP3EFYSR4",
"username": "fabiojansen",
"createdAt": "2020-05-25T17:15:16.273Z",
"updatedAt": "2020-05-25T17:15:16.273Z",
"ACL": {
"*": {
"read": true
},
"asP3EFYSR4": {
"read": true,
"write": true
}
},
"__type": "Object",
"className": "_User"
},
"sex": "male",
"createdAt": "2020-05-25T17:15:49.324Z",
"updatedAt": "2020-05-25T17:15:49.324Z"
}
]
}
Its ok, but if i want to get all the users, with the profile information in one query? Its possible? In my User class, i dont have any pointer to Profile class, only in profile class.
Is there any way?
Thanks
You have several options:
1) You can use an aggregate pipeline and $lookup the user in the Perfil class which performs a LEFT JOIN. However, this will not return an array of Parse.Object, you'd have to parse the results manually. From the docs:
{
$lookup:
{
from: <collection to join>,
localField: <field from the input documents>,
foreignField: <field from the documents of the "from" collection>,
as: <output array field>
}
}
2) You can do 2 requests by first getting all the users and then getting all their profiles by user IDs.
3) You can change your data model and add a pointer to Perfil in your User class. If you are running this query at scale it may be beneficial.
When I execute following graphQL query which has only one function and I get output which is shown below.
I want output which has largest ID or the latest timestamp.
It is possible by making change in API but my constraint is not to make any change in API and have enhance the query only, Please help me how can I achieve my goal/ desired output
Input

},
{

}
]
}
}
My expected output is this
{
"startTime": "2019-10-10 16:20:09.0"
}
or
{
"id": "1484",
"startTime": "2019-10-10 16:20:09.0"
}
One way to do this is to add a column to the Type definition, then return it from your resolver.
In Laravel (not Java), the definition:
'max' => [
'type' => Type::int(),
'description' => 'The highest score achieved'
],
and a separate query in the ORM resolver (getMaxAttribute() is referenced as simply .max()):
public function getMaxAttribute() {
return DB::table('players')->max('score');
}
will return the max for a desired column. You request the column by name in GraphQL, just like normal (eg. "{ ... max }").
