I have a data structure returned by a web service. It's a few levels deep, and could have null instead of the expected object. Which results in some ugly code to check.
<td>{{if FulfilledBy}}${FulfilledBy.Name}{{/if}}</td>
I can't change the output of the service, but I'd rather not need to check if FulfilledBy exists prior to access the .Name property.
Is there a better way to write this? I would have preferred something like
<td>${(FulfilledBy || {}).Name}</td>
but it doesn't work either.
According to docs, you can use expressions within ${}. Have you tried ${FulfilledBy? FulfilledBy.Name: 'no name'}?

I'm trying to get specific data from a bigger/nested API JSON Response. But because it's highly dynamic, it fails quite often because there are some branches missing down the JSON Tree.
Is there a good way or some best practices how to get the data?
Example:
#myrecords.cvss31 = jsonresponse["result"]["CVE_Items"][0]["impact"]["baseMetricV3"]["cvssV3"]["vectorString"]
In this case, sometimes it's throwing an error, because "cvssV3" is nil. Maybe in the future also "baseMetricV3" could be nil.
So, my approach would be to create 7 if-Statements - for every attribute. "if jsonresponse["result"].present?...", next: "if jsonresponse["result"]["CVE_Items"].present?" and so on. But that doesn't seem right.
I also tried something like "..["vectorString"].presence ||= "no NVD CVSS 3.1 Score"", but because the attribute before "vectorString" is missing, this doesn't seem to work either.
I also have a lot of other attributes to extract from that API. So basically I would have to write hundrets of conditional statements.
Is there a better way if I don't want to get ALL Data from that JSON Response extracted?
Putting it here for anyone stumbling on this issue. By using dig:
jsonresponse.dig("result", "CVE_Items", 0, "impact", "baseMetricV3", "cvssV3", "vectorString").presence || "no NVD CVSS 3.1 Score"
I'm trying to fetch results via API using the module askargs. I have no problems getting results when I have just one condition or more conditions aggregated with the operator AND where I make use of the pipe character to separate them (like written in documentation).
E.g.
[[Category:+]] AND [[Jurisdiction::A]] AND [[Type::B]]
Category:+ | Jurisdiction::A | Type::B
But the pipe character doesn't work with OR.
I need to be able to use both logical conditions with several arguments within the same query.
Am I missing something?
Am I missing something?
No. The API doesn't handle OR condition, due to simplistic code in the query parameters formatter.
See file SemanticMediaWiki/src/MediaWiki/Api/ApiRequestParameterFormatter.php
at line 132:
protected function formatConditions( $condition ) {
return "[[$condition]]";
}
Every condition in the query is formatted with surrounding brackets, leading OR to be interpreted as a page title.
An alternative is to use Special:Ask with URL encoded query and json format:
https://www.semantic-mediawiki.org/wiki/Special:Ask/-5B-5BHas-20keyword::askargs-5D-5DOR-5B-5BHas-20keyword::ask-5D-5D/-3F%3Dhelp-20page/-3FHas-20description%3Ddescription/format%3Djson
Since I came here from a website search i'm going to add another neat possibility:
If you use the Alternative separator you can use a double pipe as logical OR conjunction.
Example:
%1FCategory:+%1FJurisdiction::A%1FType::B||C
Which should be read as following
Category:+ AND Jurisdiction::A AND (Type::B OR Type::C)
Good day, collagues.
Give me the cue, pls.
In one my case for JSON parsing i am using FOR EACH component with Choice inside him.
Like this:
After http request i have in the paylaod some JSON result, which represents of some collection. Foreach treats every item from collection and compute it's properties with condition in Choice component.
I want to stop the loop when condition in Choice was found. I don't want to compare all items of result collection.
I tried to change the variable 'counter' inside the Fore each loop. But it is not working.
May be anybody has found the way?
You may not be able to do this using a for-each. But you could always have an expression/groovy script to do this loop and breaking based on your condition. Please refer this: Is there a break statement in Mule <foreach>
I've a function which is called from different components, .cfms or remotely. It returns the results of a query.
Sometimes the response from this function is manually inspected - a person may want to see the ID of a specific record so they can use it elsewhere.
The provided return formats, being wddx, json, plain all aren't very easily readable for a layman.
I'd love to be able to create a new return format: dump, where the result first writeDumped and then returned to the caller.
I know there'd be more complicated ways of solving this, like writing a function dump, and calling that like a proxy by providing the component, function and parameters so it can call that function and return the results.
However I don't think it's worth going that far. I figured it'd be great if I could just write a new return format, because that's just... intuitive and nice, and I may also be able to use that technique to solve different problems or improve various workflows.
Is there a way to create custom function returnFormats in ColdFusion 10 or 11?
(From comments)
AFAIK, you cannot add a custom returntype to a cffunction, but take a look at OnCFCRequest. Might be able to use it to build something more generic that responds differently whenever a custom URL parameter is passed, ie url.returnformat=yourType. Same net effect as dumping and/or manipulating the result manually, just a little more automated.
From the comments, the return type of the function is query. That being the case, there is simply no need for a custom return format. If you want to dump the query results, do so.
queryVar = objectName.nameOfFunction(arguments);
writeDump (queryVar);
Forgive me, I'm very new to using REST.
Currently I'm using SP2013 Odata (_api/web/lists/getbytitle('<list_name>')/items?) to get the contents of a list. The list has 199 items in it so I need to call it twice and each time ask for a different set of items. I figured I could do this by calling:
_api/web/lists/getbytitle('<list_name>')/items?$skip=100&$top=100
each time changing however many I need to skip. The problem is this only ever returns the first 100 items. Is there something I'm doing wrong or is $skip broken in the OData service?
Is there a better way to iterate through REST calls, assuming this way doesn't work or isn't practical?
I'm using the JSon protocol with the Accept Header equaling application/json;odata=verbose
I suppose the $top=100 isn't really necessary
Edit: I've looked it up more and, I'm not entirely sure of the terms here, but using $skip works fine if you're using the method introduced with SharePoint 2010, i.e., _vti_bin/ListData.svc/<list_name>?$skip=100
Actually, funny enough, the old way doesn't set a 100 item limit on returns. So skip isn't even necessary. But, if you'd like to only return a certain segment of data, you'd have to do something like:
_vti_bin/ListData.svc/<list_name>?$skip=x&$top=(x+y)
where each time through the loop you would have something like x+=y
You can either use the old method which I described above, or check out my answer below for an explanation of how to do this using SP2013 OData
Alright, I've figured it out. $skip isn't a command which is meant to be used at the items? level. It works only at the lists? level. But, there's a way to do this, actually much easier than what I wanted to do.
If you just want all the data
In the returned data, assuming the list you are calling holds more than 100 items, there will be a __next at d/__next (assuming you are using json). This __next (it is a double underscorce, keep that in mind. I had a few problems at first because I was trying to get d/_next which never returned anything) is the right URL to get the next set of items. __next will only ever be a value if there is another set of items available to get.
I ended up creating a RequestURL variable which was initially set to to original request, but was changed to d/__next at the end of the loop. Then the loop went and checked if the RequestURL was not empty before going inside the loop.
Forgive my lack of code, I'm using SharePoint Designer 2013 to make this, and the syntax isn't horribly descriptive.
If you'd only like a small set of data
There's probably a few situations where you would only want x amount of rows from your list each time you go through the loop and that's real easy to do as well.
if you just add a $top=x parameter to your request, the __next URL that comes back with the response will give you the next x rows from your list. Eventually when there are no rows left to return __next won't be returned with the response.
Don't forget that in order to use __next you need to have a
$skiptoken=Paged=TRUE
in the url as well.
