I have been trying to populate my variable bar with json fields from curl's POSTFIELDS attribute when invoking my workflow from an API using PHP. Below is a simple json passed when invoking the endpoint not as part of the URL but hidden POSTed data:
{"salesValue":5000,"authorId":2}
The properties above should be injected in Formatter Node where I generate the SQL statetement used by the ODBC driver to query our back-end database. I have been told that I can only do this, for now, by using the SCRIPT Node as I do not recall C# as having support for manipulating JSON Object out of the box. If I am behind with regards to that someone please lead me to an answer.
Question is: does Flowger support JSON Serialization, Deserialization, Decoding and/or encoding? There is a framework called JSON.Net for example. Can I use this if I want to manipulate my fgRequestBody property frfom my variable bar?
Try the below steps to get the desired results:
1 - Add a variable bar with two special properties: FgRequestBody and FgRequestContentType. Make sure that you specify the content type in the workflow, which will be application/json in your instance.
2 - Add a 'JSON Convert' directly after the start node and point your variable bar FgRequestBody to the input of Json on the Json Convert. This will convert json to xml.
3 - Add a 'XFormat' node and plug the xml output from the Json Convert to the 'XML Document' property. Right click on the node and add a new custom property with the name of the field that you would like to extract. In the custom property value, add the xpath to the value. In the Expression property of the node, add your sql statement e.g.
select * from tableName where name = '{customProperty}'
The results from this will be your sql query.
Troubleshooting Tip:
Use Postman Add-In (Chrome) or RESTClient (Firefox) to verify the results. You should see the node generation in the activity log within Flowgear. If you do not see this, then add a AllowedOrigin of * in your Flowgear Site properties. See the following for reference to this:http://en.wikipedia.org/wiki/Cross-origin_resource_sharing

var details= _clientService.GetAsync<DoctorDetails>(getDetails).Result;
I get the Result from the service which is JSON when I use "object" in the GetAsync instead of DoctorDetails. However, I don't see any property values being filled in details (All are null in DoctorDetails). DoctorDetails is the cs file of the schema I generated through xsd.
DoctorDetails is an auto generated file that contains properties like
Name
ID etc
How to deserialize this and get values in those properties (in the details variable above)
Edit
It is only returning values if I make the syntax like this
var details= _clientService.GetAsync<object>(getDetails).Result;
If you haven't already tried this option, use a library called Json.Net from Newtonsoft for json stuff. Newtonsoft json.
Provided you have the schema details and the property names match you may try the following..
var details= _clientService.GetAsync<object>(getDetails).Result;//Please check if this is a string else use .ToString()
/*
"{
'Name': 'Doctor Who',
'ID' : '1001'
}";
*/
DoctorDetails m = JsonConvert.DeserializeObject<DoctorDetails>(details);
Documentation Deserialize an Object.
I'm not promoting this library, it's just a suggestion. :)
Hope it helps.
I've been experimenting with reading SharePoint 2013 Site Column metadata from within a Word 2010 Application-level C# VSTO.
For testing I've set-up Site Columns for every type that SharePoint uses, then created a Document Content Type that ties to them all -- thus all these columns are embedded into the Word document (looks to be stored within customXml within the document file).
By reading from the _Document.ContentTypeProperties property within the VSTO's code, I can access most types, but I'm having difficulty accessing a 'Person or Group' Site Column's data -- I'm getting COM Exceptions attempting to read or write to an item's .Value property.
By looking at the XSD schema in customXml, I can see a single-value User column is made up of three values: DisplayName (type string), AccountType (type string) and AccountId (type UserId) -- however I don't see a way to read/write from/to this within the VSTO? Multi-value User columns appear to be completely different, and are made up of two string values: an ID (appears to be the SharePoint user's ID) and a string-based ID (or at least that's what I think the i:0#.w|domain\userid is, anyway).
Word itself can edit both single- and multi-valued User column data via the Document Panel, but only if Word is currently connected to SharePoint -- otherwise the functionality is disabled. I'd assume the same would be true for the VSTO, if I could access the values at all...
My two questions are:
Is there a way to read/write single- and multi-value User fields from within VSTO code (even if it's not via the _Document.ContentTypeProperties property)?
Is there a way to do Q1 when if not connected to SharePoint (if, say, the values are known to the code)?
(I've been somewhat overly verbose in case my workings so far are useful to someone else even if I get no answers; there doesn't seem to be a great amount of information about this anywhere)
With some provisos, I believe you can do read/update these fields using VSTO - although I haven't actually created a working example using VSTO, the same objects as I'd use in Word VBA are available - the code snippets below are VBA.
The person/group values that are displayed in the DIP are stored in a Custom XML Part, even when the SharePoint server is unavailable. So the problem is not modifying the values - it's a CRUD operation, in essence - but knowing what values you can use, particularly in the multi-valued case. If you know how to construct valid values (let's say you have an independent list of email addresses) then you can make the modifications locally. Personally, I don't know how I would construct a valid value for the multi-valued case so I'd basically have to contact the server.
So assuming you have the data you need to update locally...
When SharePoint serves a Word Document, it inserts/updates several Custom XML Parts. One contains a set of schemas (as you have discovered). Another contains the data. All you really need to do is access the correct Custom XML Part, find the XML Element corresponding to your SharePoint user/group column, then it's a CRUD operation on the subElements of that Element.
You can find the correct Custom XML Part using the appropriate namespace name, e.g.
Const metaPropDataUri as String = _
"http://schemas.microsoft.com/office/2006/metadata/properties"
Dim theDoc as Word.Document
Dim cxp as Office.CustomXMLPart
Dim cxps as Office.CustomXMLParts
Set theDoc = ActiveDocument
Set cxps = theDoc.CustomXMLParts.SelectByNamespace(metaPropDataUri)
If there is more than one part associate with that Namespace, I don't know for sure how to choose the correct one. AFAIK Word/Sharepoint only ever creates one, and experiments suggest that if there is another one, SharePoint works with the first one. So I use
Set cxp = cxps(1)
At this point you need to know the XML Element name of the person/group column. It may be the same as the external name (the one you can see in the SharePoint list), but if for example someone called the Sharepoint column "person group", the Element name will be "person_x0020_group". If the name isn't going to vary, you can get it from the schema XML as a one-off task. Or it may be easy to generate the correct element name from any given SharePoint name. Otherwise, you can get it dynamically from the Schema XML, which you can get (as a string) using
theDoc.ContentTypeProperties.SchemaXML
What you need to do then is find the element with attribute ma:displayName="the external name" and get the value of the name attribute. I would imagine that's quite straightforward using c#, a suitable XML object, and a bit of XPath, say
//xsd:element[#ma:displayName='person group'][1]/#name
which should return 'person_x0020_group'
You can then get the Element node for your data, e.g. something along the lines of
Dim cxn As Office.CustomXMLNode
Set cxn = cxp.SelectSingleNode("//*[name()='person_x0020_group'][1]")
Or you may find it's preferable to get the namespace Uri of the Elements in this Custom XML Part and use that to help you locate the correct node. The name is a long hex string assigned by SharePoint. You can get it from the Schema XML using, e.g.
//xsd:schema[1]/#targetNamespace
Once you have your node, you would use the known structures (i.e. the ones you have found in the Schemas) to get/modify/create child nodes as required.
of course you can. You should use the SharePoint Client-side Object model (CSOM) to manipulate SharePoint data from a location away from the server. The only thing you will need is the URL of your SharePoint site.
You can then connect through CSOM like this:
ClientContext context = new ClientContext("SITEURL");
Site site = context.Site;
Web web = context.Web;
context.Load(site);
context.Load(web);
context.ExecuteQuery();
See here an example to set a single user field:
First get the ID of the user through ensuring the username
u = context.Web.EnsureUser(UserOrGroupName);
context.Load(u);
context.ExecuteQuery();
To set the value, you can use this string format:
userid;#userloginname;#
To set the field use this:
item[myusercolumn] = "userid;#userloginname;#";
item.Update();
context.ExecuteQuery();
To set a multi user field, you can use the same code, just use ;# to concat the different usernames, such as:
item[myusercolumn] = "userid1;#userloginname1;#userid2;#userloginname2;#userid3;#userloginname3;#";
item.Update();
context.ExecuteQuery();
Hope this helps
I've been assigned to work on a project that uses the AtTask API to create an issue and accompanying custom form from a web application I've built for our intranet. I've been using this post, ATTask API - Updating Custom Field with API and C Sharp, as my main starting reference for accomplishing my task.
Like that post, I'm also getting (500) Internal Server Error, though the error I receive the URL is inserted directly into the browser is {"error":{"class":"com.attask.util.json.JSONException","message":"org.codehaus.jackson.JsonParseException: Unexpected character ('S' (code 83)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')\n at [Source: java.io.StringReader#45c828e1; line: 1, column: 6]"}}.
My URL looks like this:
https://myCo.attasksandbox.com/attask/api/v3.0/optask?method=put&projectID=myID&name=API%20SandBox%20Issue&updates={DE:Service%20Affected:Electronic%20Communications,DE:Technical%20Details:I%20dunno,DE:How%20will%20this%20change%20be%20communicated?:It%20wont}&username=myUserName&password=myPassword
I have noticed that one difference between the post I reference above and my URL is that the other post's URL is looking for a categoryID. Is that necessary for working with Custom Forms? If so, where do I find that ID? (I did a search query on an issue that had custom form of the kind I'm trying to generate, but no categoryID was returned).
By the way, my search query looks like this:
Console.WriteLine("**Searching for Change Management Issues");
JToken cmIssues = client.Search(ObjCode.ISSUE, new
{
projectID=cmProjID,
name="SandBox Issue",
name_Mod="contains",
fields="parameterValues"
});
foreach (JToken issue in cmIssues["data"].Children())
{
Console.WriteLine(issue["name"]);
Console.WriteLine(issue["categoryID"]);
Console.WriteLine(issue);
}
I've used both ISSUE & OPTASK ObjCode types, with no luck on the categoryID.
Try removing the sessionID. At the end you are using your username & password, you do not need both. Make sure you spell password correctly. In your example you spelled it wrong.
If that does not work. Make sure all the spaces are replaced with %20 by UrlEncode it before you send the call.
After finally being able to come back to this project, I found that my problems lay with my unfamiliarity with JSON calls. For this particular issue, (after the I fixed the spelling of password), I was receiving my error because I had surrounded neither the custom form object I was sending nor the related value in quotation marks.
Basically, my problem was that I was doing this:
DE:The Object:The Value
when I should have been doing this:
"DE:The Object":"The Value"
I am dynamically building the colModel for my jQGrid using fields from a DataTable. Nearly all of it works as I hoped. However, I am unable to use a custom summaryType because I can't serialize without the quotes and jQgrid doesn't look for the method if in quotes.
Presently, if I don't remove the ", I get the following error when loading the grid:
Uncaught jqGrid Grouping No such method: mysum
If I remove the quotes in the table, I get the following error when serializing:
Invalid JSON primitive: mysum.
What is the best way to tackle this problem?
You will probably have to create a solution in the view using javascript. If you manually serialize the colModel to send to the view, you will have to manually deserialize. You will not be able to parse it with a JSON parser because it will not be a valid JSON string.
One possible approach would be to use eval() on the string like this:
myObject.property = eval("mysum");
It should replace the string with the function. I am not sure if it meets your needs, but will avoid both errors you listed above.
I'm creating an app that works with ServiceNow (custom reporting tool)
It's configured to use demo12 and XML service described here.
When i made this request
https://demo12.service-now.com/incident_list.do?XML&sysparm_query=opened_at%3E2012-04-17%2000:00:00%5Eopened_at%3C2012-04-18%2000:00:00%5E&sysparm_view=
in response XML i see not only <incident> nodes, but also <u_zprototype_incidents>
XPath to get node names is
distinct-values(/xml/*/name(.))
and result is (user-friendly formatted)
<XdmValue>
<XdmAtomicValue>u_zprototype_incidents</XdmAtomicValue>
<XdmAtomicValue>incident</XdmAtomicValue>
</XdmValue>
not sure, if this is how it should be displayed.
Is there any other way (extra URI param, etc.) to get valid XML (only <incident> nodes) ?
I know that i can use /xml/*[contains(name(.),'incident')][sys_id='my GUID'] to get needed nodes. but i think it consume more CPU time than just /xml/incident[sys_id='my GUID'].
Any ideas?
For what it's worth, there's something atypical on that demo12 site. There are not supposed to be parent elements named "u_zprototype_incidents" by default. A custom table was created, extending the "incident" table, named "u_zprototype_incidents".
If you want to limit yourself ONLY to records in the base "incident" table, I would suggest that you simply add a new filter for "sys_class_name=incident". Giving you this URL:
https://demo12.service-now.com/incident_list.do?XML&sysparm_query=opened_at%3E2012-04-17%2000:00:00%5Eopened_at%3C2012-04-18%2000:00:00%5E^sys_class_name=incident&sysparm_view=
...With that you can use /xml/incident[sys_id='my GUID']
