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 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 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: '__'});
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 want to make a dynamic ng-grid , which adjusts its columns according to the key values in my JSON object. JSON object is fetched from an api. the problem I am facing is defining columns at runtime i.e The columns are not available at design time but will only be available only at runtime. I want to have something like :
http://plnkr.co/edit/q1Ye10OsIn9NOJmrICyD?p=preview
So that, I have as many columns as keys in my Json object. API's can vary so I need to make a grid which adjusts its columns.
My plunker is not working, but I hope it gives you idea, what I am trying to do.
Unless I'm misunderstanding what you want, you don't need to mess with columnDefines. Just having this:
faculty.controller('facultycontroller', function facultycontroller($scope, $http, $window){
$scope.facdata = [];
$scope.gridOptions = {
data: 'facdata'
};
$http.get("http://mtapi.azurewebsites.net/api/institute").then(function (result) {
$scope.facdata = result.data;
console.log($scope.facdata[0]);
});
});
will create the grid with a column for each key in your json.
Update
If you want to filter out any columns that begin with '$', you can do something like this:
angular.forEach(result.data[0], function(value, key){
if(key.indexOf('$') != 0)
$scope.columnDefines.push({ field: key, displayName: key});
});
Actually, you were close with what you were trying to do. You just need to put the columnDefines variable on $scope, and assign it to the gridOptions using a string, like this:
$scope.columnDefines = [];
$scope.gridOptions = {
data: 'facdata',
columnDefs: 'columnDefines'
};
Plunker
Try attaching your columnDefines variable to the scope ($scope.columnDefines). Then in your options do this:
$scope.gridOptions =
{
data: 'facdata',
columnDefs: 'columnDefines' //Note the quotes
};
This will make ng-grid watch your columnDefs for changes
I have a document like this:
{
Name : val
AnArray : [
{
Time : SomeTime
},
{
Time : AnotherTime
}
...arbitrary more elements
}
I need to update "Time" to a Date type (right now it is string)
I would like to do something psudo like:
foreach record in document.AnArray { record.Time = new Date(record.Time) }
I've read the documentation on $ and "dot" notation as well as a several similar questions here, I tried this code:
db.collection.update({_id:doc._id},{$set : {AnArray.$.Time : new Date(AnArray.$.Time)}});
And hoping that $ would iterate the indexes of the "AnArray" property as I don't know for each record the length of it. But am getting the error:
SyntaxError: missing : after property id (shell):1
How can I perform an update on each member of the arrays nested values with a dynamic value?
There's no direct way to do that, because MongoDB doesn't support an update-expression that references the document. Moreover, the $ operator only applies to the first match, so you'd have to perform this as long as there are still fields where AnArray.Time is of $type string.
You can, however, perform that update client side, in your favorite language or in the mongo console using JavaScript:
db.collection.find({}).forEach(function (doc) {
for(var i in doc.AnArray)
{
doc.AnArray[i].Time = new Date(doc.AnArray[i].Time);
}
db.outcollection.save(doc);
})
Note that this will store the migrated data in a different collection. You can also update the collection in-place by replacing outcollection with collection.
