When the first step return a json object like this
{
"success":true,
"total":21,
"items":
[
{"id":"762"},
{"id":"763"},
{"id":"764"}
]
}
how can i assign variable id to the first "id" item in response
i have done it like this but it didn't work
i also tried items.id, items[0].id but that didn't work either
To assign a variable to an item in a list, you can use a post-response script.
In this case, something like:
var data = JSON.parse(response.body);
var myId = data.items[0].id;
variables.set("id", myId);

I am trying to drop elements from JSON. Here is my code:
String test = '[{
"type":"new",
"color":"red",
"items": ["aa","bb", "cc"]
}]';
var myJson = jsonDecode(test);
var result = myJson.where((a)=> a != 'items');
print(result);
It does not work. I need to drop items and get:
[{"type":"new","color":"red"}]
In the JSON, test array contains one object item with a property items. Thus, filtering is not caching it.
To remove items, you need to map over items and remove the items key from each.
UPDATED:
var result = myJson.map((a)=> {a.remove('items'); return a;} );
I try to access to my data json file:
[{"id":1,"name":"Maria","project":[{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}]}
This is my approach:
data[0].name;
But like this I get only the result:
Animals
But I would need the result:
Animals, Cats
You are accessing only the name property of 0th index of project array.
To access all object at a time you need to loop over the array.
You can use Array.map for this.
var data = [{"id":1,"name":"Maria","project":[{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}]}]
var out = data[0].project.map(project => project.name).toString()
console.log(out)
If that's your actual data object, then data[0].name would give you "Maria". If I'm reading this right, though, you want to get all the names from the project array. You can use Array.map to do it fairly easily. Note the use of an ES6 arrow function to quickly and easily take in the object and return its name.
var bigObject = [{"id":1,"name":"Maria","project":[{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}]}];
var smallObject = [{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}];
console.log("Getting the names from the full array/data structure: "+bigObject[0].project.map(obj => obj.name))
console.log("Getting the names from just the project array: "+smallObject.map(obj => obj.name))
EDIT: As per your comment on the other answer, you said you needed to use the solution in this function:
"render": function (data, type, row) {if(Array.isArray(data)){return data.name;}}
To achieve this, it looks like you should use my bottom solution of the first snippet like so:
var data = [{"id":5,"name":"Animals"},{"id":6,"name":"Cats"}];
function render(data, type, row){
if(Array.isArray(data)){
return data.map(obj => obj.name);
}
};
console.log("Render returns \""+render(data)+"\" as an array.");
I am new to both JSON and Postman(as of yesterday).
I'm trying to do something very simple, I've created a GET request which pulls in a list of forms in a JSON response. I want to take this response and get the first "id" token and place it in a variable.
I am using a global variable but would like to use a collection variable if possible. Either way here is what I am doing.
I've tried several things, most recently this:
var jsonData = JSON.parse(responseBody);
postman.setGlobalVariable("id", jsonData.args.id);
As well as this:
pm.test("GetId", function () {
var jsonData = pm.response.json();
pm.globals.set("id", jsonData.id);
});
Response code looks like this:
{
"forms":[
{
"id":"3197239",
"created":"2018-09-18 11:37:39",
"db":"1",
"deleted":"0",
"folder":"151801",
"language":"en",
"name":"Contact Us",
"num_columns":"2",
"submissions":"0",
"submissions_unread":"0",
"updated":"2018-09-18 12:02:13",
"viewkey":"xxxxxx",
"views":"1",
"submissions_today":0,
"url":"https://xxx",
"data_url":"",
"summary_url":"",
"rss_url":"",
"encrypted":false,
"thumbnail_url":null,
"submit_button_title":"Submit Form",
"inactive":false,
"timezone":"US/Eastern",
"permissions":150
},
{
"id":"3197245",
"created":"2018-09-18 11:42:02",
"db":"1",
"deleted":"0",
"folder":"151801",
"language":"en",
"name":"Football Draft",
"num_columns":"1",
"submissions":"0",
"submissions_unread":"0",
"updated":"2018-09-18 12:11:54",
"viewkey":"xxxxxx",
"views":"1",
"submissions_today":0,
"url":"https://xxxxxxxxx",
"data_url":"",
"summary_url":"",
"rss_url":"",
"encrypted":false,
"thumbnail_url":null,
"submit_button_title":"Submit Form",
"inactive":false,
"timezone":"US/Eastern",
"permissions":150
}
]
}
This would get the first id:
pm.globals.set('firstId', _.first(pm.response.json().forms).id)
That would get the first in the array each time so it would set a different variable it that response changed.
The test that you created was nearly there but the reference needed to go down a level into the forms array:
pm.test("GetId", function () {
var jsonData = pm.response.json()
pm.expect(jsonData.forms[0].id).to.equal("3197239")
pm.globals.set("id", jsonData.forms[0].id)
})
The [0]is referencing the first id in the first object within the array. For example [1] would get the second one and so on.
You currently cannot set a collection level variable using the pm.* API - These can only be added manually and referenced using the pm.variables.get('var_name') syntax.
Edit:
In the new versions of the desktop app you can set variables at the Collection level using pm.collectionVariables.set().
Based on the name or any other attribute if you want to set the id as a global variable then this is the way.
for(var i=0; i<jsonData.forms.length; i++)
{
if (jsonData.forms[i].name==="Contact Us")
{
pm.environment.set("id", jsonData.forms[i].id);
}
}
I've a JSON object as below:
let data = [{"grade":"A","batch":"night", "rating":5}, {"grade":"B", "batch":"morning", "rating":6},
{"grade":"C", "batch":"night", "rating":7},
{"grade":"A", "batch":"morning", "rating":8}]
I want to filter json on two properties of object named "grade" and "batch"
How can I do this in javascript?
Here is sample code. you can add the filters object whichever data you want to filter and run the code. The result will be displayed in the console of the window.
You can try running the code snippet for output
function multiFilter(array, filters){
const filterKeys = Object.keys(filters);
// filters all elements passing the criteria
return array.filter((item) => {
// dynamically validate all filter criteria
return filterKeys.every(key => !!~filters[key].indexOf(item[key]));
});
}
let data = [{"grade":"A","batch":"night", "rating":5}, {"grade":"B", "batch":"morning", "rating":6},
{"grade":"C", "batch":"night", "rating":7},
{"grade":"A", "batch":"morning", "rating":8}]
let filters = {
"grade" : ["A", "B"],
"batch" : ["morning"]
};
let filtered = multiFilter(data, filters);
console.log(filtered);
I am using the npm flat package, and arrays/objects are flattened, but object/array keys are surrounded by '' , like in 'task_status.0.data' using the object below.
These specific fields do not get stored into AzureTables - other fields go through, but these are silently ignored. How would I fix this?
var obj1 = {
"studentId": "abc",
"task_status": [
{
"status":"Current",
"date":516760078
},
{
"status":"Late",
"date":1516414446
}
],
"student_plan": "n"
}
Here is how I am using it - simplified code example: Again, it successfully gets written to the table, but does not write the properties that were flattened (see further below):
var flatten = require('flat')
newObj1 = flatten(obj1);
var entGen = azure.TableUtilities.entityGenerator;
newObj1.PartitionKey = entGen.String(uniqueIDFromMyDB);
newObj1.RowKey = entGen.String(uniqueStudentId);
tableService.insertEntity(myTableName, newObj1, myCallbackFunc);
In the above example, the flattened object would look like:
var obj1 = {
studentId: "abc",
'task_status.0.status': 'Current',
'task_status.0.date': 516760078,
'task_status.1.status': 'Late',
'task_status.1.date': 516760078,
student_plan: "n"
}
Then I would add PartitionKey and RowKey.
all the task_status fields would silently fail to be inserted.
EDIT: This does not have anything to do with the actual flattening process - I just checked a perfectly good JSON object, with keys that had 'x.y.z' in it, i.e. AzureTables doesn't seem to accept these column names....which almost completely destroys the value proposition of storing schema-less data, without significant rework.
. in column name is not supported. You can use a custom delimiter to flatten your objects instead.
For example:
newObj1 = flatten(obj1, {delimiter: '__'});
