I'm having trouble understanding how to check if a List of Maps contain a value by a key. Below is the structure of data I have.
[
{
id: 1,
bookTxt: Hereissomebooktext.,
bookAuth: Charles
},
{
id: 3,
bookTxt: Hereissomemorebooktext.,
bookAuth: Roger
},
{
id: 6,
bookTxt: Hereissomeevenmorebooktext.,
bookAuth: Matt
}
]
I'm trying to write something simple or a function to see if this List of Maps contains a certain 'id'. I know that List has the Contains method but in my case I have to find a value within a list of Maps.
For example if I want to see if the List of Maps above contains the id of 3, how would I be able to access that?
Direct way to check
if (list[0].containsKey("id")) {
if (list[0]["id"] == 3) {
// your list of map contains key "id" which has value 3
}
}
And for indirect way you need to iterate through the loop like this:
for (var map in list) {
if (map?.containsKey("id") ?? false) {
if (map!["id"] == 3) {
// your list of map contains key "id" which has value 3
}
}
}
Maybe iterating over the maps in the list, then ask to every map to get key you want, and check the content for what you want.

I have an issue that I'm hoping someone can help me with. I'm pretty new to coding and Gatling, so I'm not sure how to proceed.
I'm using Gatling (with Scala) to create a performance test scenario that contains two API-calls.
GetInformation
SendInformation
I'm storing some of the values from the GetInformation response so I can use it in the body for the SendInformation request. The problem is that some information from the GetInformation response needs to be edited/removed before it is included in the body for SendInformation.
Extract of the GetInformation response:
{
"parameter": [
{
"name": "ResponseFromGetInfo",
"type": "document",
"total": 3,
"entry": [
{
"fullUrl": "urn:uuid:4ea859d0-daa4-4d2a-8fbc-1571cd7dfdb0",
"resource": {
"resourceType": "Composition"
}
},
{
"fullUrl": "urn:uuid:1b10ed79-333b-4838-93a5-a40d22508f0a",
"resource": {
"resourceType": "Practitioner"
}
},
{
"fullUrl": "urn:uuid:650b8e7a-2cfc-4b0b-a23b-a85d1bf782de",
"resource": {
"resourceType": "Dispense"
}
}
]
}
]
}
What I want is to store the list in "entry" and remove the entries with resourceType = "Dispense" so I can use it in the body for SendInformation.
It would have been ok if the entry list always had the same number of entries and order, but that is not the case. The number of entries can be several hundred and the order of entries varies. The number of entries are equal to the "total" value that is included in the GetInformation response.
I've thought about a few ways to solve it, but now I'm stuck. Some alternatives:
Extract the entire "entry" list using .check(jsonPath("$.parameter[0].entry").saveAs("entryList")) and then iterate through the list to remove the entries with resourceTypes = "Dispense".
But I don't know how to iterate over a value of type io.gatling.core.session.SessionAttribute, or if this is possible. It would have been nice if I could iterate over the entry list and check if parameter[0].entry[0].resourceType = "Dispense", and remove the entry if the statement is true.
I'm also considering If I can use StringBuilder in some way. Maybe if I check one entry at the time using .check(parameter[0].entry[X].resourceType != dispense, and if true then append it to a stringBuilder.
Does someone know how I can do this? Either by one of the alternatives that I listed, or in a different way? All help is appreciated :)
So maybe in the end it will look something like this:
val scn = scenario("getAndSendInformation")
.exec(http("getInformation")
.post("/Information/$getInformation")
.body(ElFileBody("bodies/getInformtion.json"))
// I can save total, så I know the total number of entries in the entry list
.check(jsonPath("$.parameter[0].total").saveAs("total"))
//Store entire entry list
.check(jsonPath("$.parameter[0].entry").saveAs("entryList"))
//Or store all entries separatly and check afterwards who have resourceType = "dispense"? Not sure how to do this..
.check(jsonPath("$.parameter[0].entry[0]").saveAs("entry_0"))
.check(jsonPath("$.parameter[0].entry[1]").saveAs("entry_1"))
//...
.check(jsonPath("$.parameter[0].entry[X]").saveAs("entry_X"))
)
//Alternativ 1
.repeat("${total}", "counter") {
exec(session => {
//Do some magic here
//Check if session("parameter[0]_entry[counter].resourceType") = "Dispense" {
// if yes, remove entry from entry list}
session})}
//Alternativ 2
val entryString = new StringBuilder("")
.repeat("${total}", "counter") {
exec(session => {
//Do some magic here
//Check if session("parameter[0]_entry[counter].resourceType") != "Dispense" {
// if yes, add to StringBuilder}
// entryString.append(session("parameter[0]_entry[counter]").as[String] + ", ")
session})}
.exec(http("sendInformation")
.post("/Information/$sendInformation")
.body(ElFileBody("bodies/sendInformationRequest.json")))

Gatling with Java would probably be an easier solution for you.
check(jsonPath("$.parameter[0].entry").saveAs("entryList"))
This is going to capture a String, not a list. In order to be able to iterate, you have to use ofXXX/ofType[], see https://gatling.io/docs/gatling/reference/current/core/check/#jsonpath
Then, in order to generate the next request's body, you could consider a templating engine such as PebbleBody (https://gatling.io/docs/gatling/reference/current/http/request/#pebblestringbody) or indeed use StringBody with a function with a StringBuilder.
I just started using Primsa 2 so I am still a noob at this but all I am trying to do is create a flat array of strings(Array<number>) based on the values I get from a specific field. Right now when I target that field it gives me an array of objects like this: userIds: [{ issueId: 1, userId: 1 }]
All I want is the value I get from the userId key and the array to return like this userIds: [ 1 ]. I was able to fix this with some formatting code after the query which was done like so:
const issues = project.issues.map(issue => ({ ...issue, userIds: [...issue.userIds.map((id) => id.userId)] }))
const _project = { ...project, issues }
However, this doesn't seem like the most optimal solution. If this is the only way that is fine but I assume with the power that Prisma has for querying, this is something I can do just in the query alone?
For reference, my query currently looks like this:
const project = await prisma.project.findFirst({
where: { id: req.currentUser.projectId },
include: { users: true, issues: { include: { userIds: true } } },
})
Thanks in advance!
Can you show your schema? Perhaps you can model the relation differently. However, unless if you provide a field, userIds, that is a flat array and not a field of a an other relation it will be returned as a list of objects as you have already.
So i have a function that basically sorts a MAP of MAP's, but it uses different MAP properties for the sort, so i want to sort by age or by name based on the user input.
{
"name": "John",
"other_data:
{
"age": "20",
"nickname": "Doe2020"
}
}
So my idea was to make a generic function to sort this. There is some way where i can send the path of each property as a function argument to sort based on this argument ?
Like "mySortFunction(MapPath: ["other_data"]["age"]);"
or "mySortFunction(MapPath: ["name"]);"
Thanks!
You could try something like this, if your properties are at max two levels:
mySortFunction(Map map, {String firstLevel, String secondLevel}){
if(firstLevel != null){
if(secondLevel != null){
sortMap(map[firstLevel][secondLevel]); // Your sorting logic here
} else {
sortMap(map[firstLevel]); // sorting logic strikes back
}
}
}
You can add more optional variables and increase the if logic for deeper maps
iam making a flutter app that depending on odoo
and i want to get all fields in a module
so iam using read method
and iam depending on this library
http://oogbox.com/page/odoo-api-flutter.html
https://pub.dartlang.org/packages/odoo_api/versions/1.0.1
the problem is that i tried everything to get all ids
i changed the List ids to []
and to null
and nothing working
and this is the code
final ids = [1, 2, 3, 4, 5];
final fields = ["id", "name", "email"];
client.read("res.partner", ids, fields).then((OdooResponse result) {
if (!result.hasError()) {
List records = result.getResult();
} else {
print (result.getError());
}
});
From the documentation this read method doesn't allow you to bring all records, you should use searchRead() and pass to the domain param an empty list to do that.
I have a Dojo EnhancedGrid which uses a data store filled with the following data structure:
[
{ id: 1, desc: "Obj Desc", options: [ { txt: "text", value: 0 }, { obj2 }, { objn } ] },
{ id: 2, ... },
{ id: 3, ... },
{ id: n, ... }
]
Currently I'm doing all this with an auxiliary store...but I believe this is far from a good approach to the problem, it's too ugly and doesn't work really well with edition (because I have to send changes from one store to another).
Instead of displaying all this objects at the same time, I wanted to select just one object (using its id) and display its options objects on grid. At the same time, the changes on grid should make effect on store, to be able to save them later.
Is it possible to query the grid's store, in order to display just one object? How?
And is it possible to fill the grid with objects list present on "options" attribute?
