In April, I started a new job. Among my duties at this point is working on converting the organization’s C#-based web parts to IQA queries and JavaScript widgets that make use of the API provided by ASI’s iMIS.

ASI’s API documentation is very thorough in some places, and frustratingly fragmentary in others. My goal here is to explain how to create a basic IQA query, which is easy enough, and to provide working HTML and JavaScript that will allow you to run that query that returns records with a specific last name and display the results to an iMIS-based website user.

As a reference point, I am using iMIS 20.2.65.9955 as the basis for this tutorial.

Building your IQA query

To begin, access your iMIS staff site, perhaps at https://www.example.org/Staff, and go to RiSE > Intelligent Query Architect. You’ll see a number of existing folders. I recommend creating a folder and if necessary subfolders of your own so that you can easily keep track of the queries that you create. For purposes of the JavaScript code I’ll share later on, I’ll name my folder MyTests.

Click New > Query, then enter a name for your query. For purposes of this tutorial, I’m going to name my query LastName-Test.

• On the Sources tab, click Add Source. Double-click the CsContact business object listed in the window that appears, or select it and click OK.
• On the Filters tab, select Full Name from the Property select box in the first row, then click + to ensure the filter is added to the query. In the second row, select Name (Last, First) from the Property select box, enter "@url:LastName" (with the double quotes) in the corresponding Value box, and then click + in that row.
• On the Display tab, you can choose which pieces of information you want available in the query. The only one with which we’re concerned for this tutorial is Full Name, which is checked by default.
• On the Sorting tab, choose Name (Last, First) from the Property select box, then click + to ensure the sorting is added to the IQA.
• Finally, if you want everyone to be able to see the results even if they’re not logged in to the website, select Share (Everyone) on the Security tab.

Click Save. Your IQA query is complete!

Displaying IQA results on a webpage

iMIS offers some iParts such as Query Menu that do a fine job of displaying results so long as you don’t need to apply special formatting or manipulate it in some way. For this tutorial, I’m not going to use those iParts, but will instead demonstrate how to use HTML and JavaScript including jQuery which is part of the iMIS website in order to display results.

On the iMIS staff site, navigate to RiSE > Page Builder > Manage content, navigate to a folder, and choose New > Website Content. Enter a Title and Publish file name, then click Add content and choose the Content HTML iPart. Select the HTML tab and then enter the following HTML:

<div id="imis-json-results" class="json-results">
    <p id="imis-json-results-loading" class="loading-results">Loading results…</p>
</div>

This is the container into which we’ll load the results retrieved from our API call.

Next, enter the following JavaScript:

<script type="text/javascript">
    // we’ll display these messages only if results can’t be displayed
    var msgNoResults = "No results found.";
    var msgAjaxError = "The results failed to load. Please try again later."
    
    // create unordered list for insertion into DIV#imis-json-results
    var resultList = document.createElement("ul");
    resultList.id = "imis-results";
    
    // set URL for API call to retrieve names
    // note the QueryName parameter includes folder name and IQA query name
    // the LastName parameter is used due to the "@url:LastName" that we entered while building our IQA query
    // the Limit parameter defines the maximum number of results to be returned
    var apiURL = "/api/IQA?QueryName=$/MyTests/LastName-Test&LastName=Smith&Limit=500";
    
    // make ajax call to API to retrieve names
    jQuery.ajax(apiURL, {
        type: "GET",
        contentType: "application/json",
        headers: {
        
            // this line retrieves the __RequestVerificationToken value that iMIS automatically populates onto the webpage, eliminating the need for separate authentication
            RequestVerificationToken: document.getElementById("__RequestVerificationToken").value
        },
        success: function(data) {
        
            // if you want to see raw data returned by API, uncomment following line and view results in web browser’s developer console
            // console.log(data);
            
            // display results if any were found
            if (data["TotalCount"] > 0) {
            
                // loop through values in JSON string
                for (var i = 0; i < data["Items"]["$values"].length; i++) {
                    var fullName = "";
                    
                    // get properties for specific record, then loop through them
                    var record = data["Items"]["$values"][i]["Properties"]["$values"];
                    for (var j = 0; j < record.length; j++) {
                        if (record[j].Name == "FullName") {
                            fullName = record[j].Value;
                        }
                    }
                    
                   // create list item, list item to unordered list created earlier
                   var resultItem = document.createElement("li");
                   resultItem.innerHTML = fullName;
                   resultList.appendChild(resultItem);
               }
           }
           
           // eliminate loading message
           var loadingElem = document.getElementById("imis-json-results-loading");
           loadingElem.parentElement.removeChild(loadingElem);
           
           // append results or message indicating no results were found to DIV#imis-json-results
           if (data["TotalCount"] > 0) {
                document.getElementById("imis-json-results").appendChild(resultList);
            }
            else {
                var noResultsP = document.createElement("p");
                noResultsP.innerHTML = msgNoResults;
                document.getElementById("imis-json-results").appendChild(noResultsP);
            }
        },
        error: function() {
            // eliminate loading message
            var loadingElem = document.getElementById("imis-json-results-loading");
            loadingElem.parentElement.removeChild(loadingElem);
            
            // append ajax error message to DIV#imis-json-results
            var ajaxErrorP = document.createElement("p");
            ajaxErrorP.innerHTML = msgAjaxError;
            document.getElementById("imis-json-results").appendChild(ajaxErrorP);
        }
    });
</script>

Again, the Query Menu iPart may be sufficient for displaying very basic lists, but for more involved projects, this should at least give you a starting point for getting data out of your iMIS database using the API.
