I have below json
[
{
"id": 13059,
"xid": "81f4278a53fe4c1a8d03346a34d76a47",
"yid": "8cbefbadec52ced5:e4f6801:17c73aeaf21:-5a75"
},
{
"id": 13059,
"xid": "061ef5792e8f4603bb1f86c71e6fb16c",
"yid": "8cbefbadec52ced5:e4f6801:17c73aeaf21:-5a56"
},
{
"id": 13061,
"xid": "4290987b25b34ffbb5b0329f1ab1b673",
"yid": "8cbefbadec52ced5:e4f6801:17c73aeaf21:-5dd4"
},
{
"id": 13063,
"xid": "57c4a2790aa44376be1e5215c5cb7ad0",
"yid": "8cbefbadec52ced5:e4f6801:17c73aeaf21:-585e"
}
]
Now I put the above json in global variable in JSR223 sampler
vars.put("jsonVariable",JSON.stringify(aboveJson))
Now next I add "ForEach Controller" and add
InputVariable Prefix = jsonVariable
Output variable name = outVariable
Then I add another JSR223 sampler inside ForEach Controller and log below data
log.info(${outVariable})
But ForEach controller is not even executing for once. Please let me know where I did wrong
ForEach Controller isn't smart enough to parse your JSON structure, it iterates an individual set of JMeter Variables which looks like:
var_1=foo
var_2=bar
etc.
so depending on what you're trying to achieve you need to:
In case if you want individual values of id, xid and/or yid - add 1 or more JSON Extractors and configure them to fetch the values from the response. Then use ForEach Controller and feed the variable from JSON Extractor to it
If you want to iterate JSON Objects instead you can use JSR223 PostProcessor and the following Groovy code:
new groovy.json.JsonSlurper().parse(prev.getResponseData()).eachWithIndex { entry, int index ->
vars.put('json_' + (index + 1), new groovy.json.JsonBuilder(entry).toString())
}

I would like to filter array inside a filter. First I have a big array of Staff object (self.bookingSettings.staffs). Inside this array I have multiple object like this :
"staffs": [
{
"id": 1,
"name": "Brian",
"services": [
{
"id": 1
},
{
"id": 2
},
{
"id": 3
},
{
"id": 4
}
],
"pos": 1
},...
I would like to filter this array in order to have only services with id = 3.
I succeed to have if first object is equal to 3 with this code :
self.bookingSettings.staffs.filter({ $0.services.first?.id == self.bookingService.id })
but that takes only the first item.
I think I have to filter inside my filter function, something like this to loop over all object inside services :
self.bookingSettings.staffs.filter({ $0.services.filter({ $0.id == self.bookingService.id }) })
but I've the following error: Cannot convert value of type [BookingService] to closure result type Bool.
Is this a good idea ? How can I achieve this ?
You could use filter, which would look something like this:
self.bookingSettings.staffs.filter {
!$0.services.filter{ $0.id == self.bookingService.id }.isEmpty
}
This code is constructing an entire array of filtered results, only to check if its empty and immediately discard it. Since filter returns all items that match the predicate from the list, it won't stop after it finds a match (which is really what you're looking for). So even if the first element out of a list of a million elements matches, it'll still go on to check 999,999 more elements. If the other 999,999 elements also match, then they will all be copied into filter's result. That's silly, and can use way more CPU and RAM than necessary in this case.
You just need contains(where:):
self.bookingSettings.staffs.filter {
$0.services.contains(where: { $0.id == self.bookingService.id })
}
contains(where:) short-circuits, meaning that it won't keep checking elements after a match is found. It stops and returns true as soon as find a match. It also doesn't both copying matching elements into a new list.
I have on query parameter which is little bit complex and i have my own syntax to make that value. Its has more then one variable to make one complete string value.
Let suppose name of parameter is index which has row and column like to make this value 20:30
index = { row: 20, col:30 }
index2 = { row: 20, col:30, chr: 15 }
Now i wanted to make it as
example.com?index=20:30
example.com?index2=20:30:15
Can someone tell me how can i define this in swagger ?
Thank you.
Make your swagger parameter a string and in your code behind handle the splitting into multiple variables...
I do exactly that here:
http://turoapi.azurewebsites.net/swagger/ui/index#/Echo/Echo_Get
"parameters": [
{
"name": "location",
"in": "query",
"description": "SoFL= 26.16,-80.20",
"required": true,
"type": "string"
},
That location is (Latitude,Longitude) and I split it with a C# TypeConverter
...and the request looks like:
http://turoapi.azurewebsites.net/api/Echo?location=26.16,-80.20
The code for that WebApi is here:
https://github.com/heldersepu/TuroApi
I have the following in php:
$follow=explode(" ",$_SESSION['Following']); //create array from the string stored in session variable
foreach($follow as $val) {
$show = $val;
//my query
$result=mysqli_query($dbc,$query);
WHILE ($rows = mysqli_fetch_assoc($result)) {
//$array[]= $rows; // tried this
//$array=json_encode($rows); //tried this
//array_push($array,$rows); // tried this
}
$json_array=json_encode($array);
echo $json_array;
If I take a single pass through the foreach loop the json object looks like this:
[{key:value}....], which can be parsed in my javascript.
However, with multiple passes in the foreach I am getting multiple arrays
within the object ,like this: [{key:value}][{key:value}]..... which results in the following
SyntaxError: JSON.parse: unexpected non-whitespace character after JSON data, which I guess are the []'s inside the object. How can I create the json object in the foreach loop to fix this?
Fixed it. I was echoing $json_array inside the foreach loop.
I am using rails 3 with backbone.js 0.53 and currently receive a GET with the following array:
[{"credit_card":
{"id":2,"cc_number":"12345678912345","cc_type":"stack","owner":"overflow"}},
....next objects....]
I have read a lot of the other threads but can't figure out how to access the values.
Is there any way to do this with the backbone-given methods like .get()?
I tried
myArray = eval(arrayJSON)
alert myArray.length #works
but any other way of accessing the single values in an array or iterating over it fails.
Probably I am just missing something here.
Quick example of how to iterate through all your results via underscore:
/* received results mocking */
model.attributes = [
{ "credit_card" : { "id":2, "cc_number":"12345678912345" },
{ "credit_card" : { "id":3, "cc_number":"44444444455555" },
{ "credit_card" : { "id":4, "cc_number":"66666655554332" }
]
/* lets get all results */
results = model.toJSON()
/* loop through all results */
_(results).each(item) {
console.log(item.credit_card.id);
}
/* get result by array pos */
console.log(results[1]); // get 2nd item
Cheers
It might be useful to see more details, but in general you should be able to access elements just fine with the following syntax: alert(myArray[0].credit_card.cc_number);
I even pasted your sample array into jsFiddle and had no issues: http://jsfiddle.net/P4w7T/1/
I have a problem "joining" some documents in a view. Here's my schema: Documents with type "category" can hold an embedded array of ids to documents with type "page". Both have a field "name".
My Documents:
{
"_id": "887c28dcf6dd8429d404d276b900b203",
"_rev": "3-c4d1e0c8378bb0081b5fe3522ee649a0",
"TYPE": "category",
"NAME": "Home",
"PAGES": [
{"PAGE_ID": "887c28dcf6dd8429d404d276b900ad8f"},
{"PAGE_ID": "887c28dcf6dd8429d404d276b900b203"},
{"PAGE_ID": "887c28dcf6dd8429d404d276b900bae0"}
]
}
{
"_id": "887c28dcf6dd8429d404d276b9008c01",
"_rev": "1-afd54c654ae5afa56a3fbd7b1ba119d2",
"TYPE": "page",
"NAME": "Foo"
}
Now I want to join these in a view with this map function:
function(doc) {
if (doc.TYPE == "category") {
for (id in doc.PAGES) {
emit(doc.NAME, doc.PAGES[id].PAGE_ID);
}
}
}
But instead of the PAGE_ID I want the NAME of the referencing document.
This is basically the example from the CouchDB wiki, but they don't show the map function. So any ideas?
You need to include a _id field somewhere in your output value. After that, you use include_docs=true and the view will include the linked document instead of the source document. For example:
function(doc) {
if (doc.TYPE == "category") {
for (var x = 0; x < doc.PAGES.length; x++) {
emit(doc.NAME, { _id: doc.PAGES[x].PAGE_ID });
}
}
}
When you query this view, you add include_docs=true to your URL. And your view output will add a new field to each row called doc. Ordinarily, that field will contain the full source document. In this case, it will include the linked document you are referring to.
EDIT Btw, you're using the for...in loop incorrectly. A for...in is used to loop over the properties of an object. You need to use a simple for loop to iterate an array like this.
