Creating an attendance register report

Creating an attendance register report

GlyndwrGlyndwr Posts: 65Questions: 14Answers: 0

I want to create an attendance register report that looks like this:

The information above the dates is the lesson for that day.

The JSON being returned to the jQuery is:

[{"attId":"120","cdId":"MTQ5","attMeeting":"A","attDate":"2019-01-11","cdSurname":"Achilles","cdFirstName":"Tendon","attDescription":"Cycling","attNewChum":"N"},{"cdId":"ODA=","cdSurname":"Alistair","cdFirstName":"Tricia","attDescription":"Running","attNewChum":"N"},{"cdId":"MTQ5","cdSurname":"Achilles","cdFirstName":"Tendon","attDescription":"Cycling","attNewChum":"N"},{"attId":"121","cdId":"ODA=","attMeeting":"P","attDate":"2019-01-12","cdSurname":"Alistair","cdFirstName":"Tricia","attNewChum":"N"},{"attId":"122","cdId":"MTQ5","attMeeting":"P","attDate":"2019-01-13","cdSurname":"Achilles","cdFirstName":"Tendon","attDescription":"Rowing","attNewChum":"N"},{"attId":"123","cdId":"ODA=","attMeeting":"P","attDate":"2019-01-13","cdSurname":"Alistair","cdFirstName":"Tricia","attDescription":"Rowing","attNewChum":"N"}]

The mySQL that extracts the data has a Left Join so all the names are extracted if there is a date (i.e., you can have a name followed by all columns having blanks).

Is it possible to do this?

Kind regards,

Glyn

    Yes it is certainly possible to display a DataTable like that, but you'd need to transform the JSON into a row based structure. DataTables requires that each item (array or object) in the array of data fed to the table represent a whole row.

    Hi Allan,

    I have been able to transform the JSON into a row based structure:

    jsonString: [{"attId":"MTIw","cdId":"MTQ5","cdSurname":"Achilles","cdFirstName":"Tendon","cdArchived":"null","attNewChum":"N","2016-08-24":"null","2016-08-25":"null","2016-08-26":"null","2016-08-27":"null","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"A","2019-01-11":"null"},{"attId":"NzQ=","cdId":"ODA=","cdSurname":"Alistair","cdFirstName":"Tricia","cdArchived":"null","attNewChum":"N","2016-08-23":"a","2016-08-24":"null","2016-08-25":"null","2016-08-26":"null","2016-08-27":"null","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2016-08-24":"f","2016-08-25":"null","2016-08-26":"null","2016-08-27":"null","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2016-08-25":"a","2016-08-26":"null","2016-08-27":"null","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2016-08-26":"Y","2016-08-27":"null","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2016-08-27":"a","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2016-08-28":"null","2016-09-30":"Y","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2017-03-04":"y","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2017-03-05":"Y","2017-07-05":"null","2017-07-12":"null","2019-01-11":"null","2017-07-05":"Y","2017-07-12":"null","2019-01-11":"null","2017-07-12":"Y","2019-01-11":"null","2017-07-12":"null","2019-01-11":"null"}]

    I have then tried to use this example:
    https://datatables.net/forums/discussion/comment/117303/#Comment_117303

    However, I get the console error:

    Please note that the code I added from the example is:

    var columns = [];
     responseJson1a = JSON.parse(responseJson1a);
     columnNames = Object.keys(responseJson1a.data[0]);
     for (var i in columnNames) {
     columns.push({responseJson1a: columnNames[i], title: columnNames[i]});
    }
    

    Without this code the columns defined in the HTML are displayed. So all I need to do now is add the dynamic date columns (there can be 0 to n date columns).

  • colincolin Posts: 3,593Questions: 0Answers: 633

    Hi @Glyndwr ,

    That's a lot of coding going on there. We're happy to take a look, but as per the forum rules, please link to a test case - a test case that replicates the issue will ensure you'll get a quick and accurate response. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

    Cheers,

    Colin

    Hi Colin,

    I am not sure how to do this as I am using a json string not html embedded data. Never the less, I have tried to do it here: http://live.datatables.net/fegacevu/1/edit

  • allanallan Posts: 48,883Questions: 1Answers: 7,122 Site admin

    dataType: "json";

    Not sure what your intention is there, but I don't think that's even valid Javascript. Drop those two lines.

    responseJson1a = JSON.parse(responseJson1a);

    If you are getting a JSON parsing error from that line, then responseJson1a is not a valid JSON string. Use JSONLint to validate the string (i.e. add console.log( responseJson1a ); just before that line and then put the string into the linter.

    Yes, that works to complete the columns:
    <th>Att. ID</th>
    <th>CD ID</th>
    <th>Surname</th>
    <th>First Name</th>
    <th>Archived Date</th>
    <th>New Chum</th>

    All I need is how to dynamically create the column headers for the date columns:
    "2016-08-24":"null","2016-08-25":"null","2016-08-26":"null","2016-08-27":"null","2016-08-28":"null","2016-09-30":"null","2017-03-04":"null","2017-03-05":"null","2017-07-05":"null","2017-07-12":"null","2019-01-11":"A","2019-01-11":"null"},

    I tried:

    var columns = [];
     responseJson1a = JSON.parse(responseJson1a);
     columnNames = Object.keys(responseJson1a.data[0]);
     for (var i in columnNames) {
     columns.push({responseJson1a: columnNames[i], title: columnNames[i]});
    }
    

    from the example: https://datatables.net/forums/discussion/comment/117303/#Comment_117303

    However, that gave me the console error:

    Uncaught SyntaxError: Unexpected token o in JSON at position 1
    at JSON.parse (<anonymous>)
    at Object.<anonymous> (attendanceReport.js:172)
    at u (jquery.min.js:2)
    at Object.fireWith [as resolveWith] (jquery.min.js:2)
    at k (jquery.min.js:2)
    at XMLHttpRequest.<anonymous> (jquery.min.js:2)
    

    Without that code the first six columns are correctly populated. So I need the correct code to dynamically create the column headers for the date columns.

    Kind regards,

    Glyn

    Did you use JSONLint as Allan recommended?
    Have you updated your example?

  • allanallan Posts: 48,883Questions: 1Answers: 7,122 Site admin

    We'd really need a test case showing the issue in this case. I'm afraid we can't really help without one.

    Hi,

    I very much appreciate your help. I have created another link http://live.datatables.net/kuhobodu/1/edit

    I hope this is acceptable. The trouble is I do not know how to provide an input file in place of the HTML in order to better demonstrate the problem.

  • tangerinetangerine Posts: 2,216Questions: 17Answers: 244

    Your example Javascript is showing errors. They include "dataType: "json"; which Allan already suggested should be removed..

  • GlyndwrGlyndwr Posts: 65Questions: 14Answers: 0

    Hi Tangerine,

    Thank you for your help. I have been working on this in my spare time and found a few things. I have removed the "dataType: "json"; and this makes no difference. I have also found that:

    var varColumns = [];
        $.each(responseJson1a, function(key1, value){
            $.each(value, function(key, value){
                alert(key);
                alert(value);
                varColumns.push({data: key, title: key});
            });
     });
    

    placed in the ".done" function displays the key and value and so replaces:

    var columns = [];
         responseJson1a = JSON.parse(responseJson1a);
         columnNames = Object.keys(responseJson1a.data[0]);
         for (var i in columnNames) {
            columns.push({responseJson1a: columnNames[i], title: columnNames[i]});
        }
    

    So now I need to find out how to use this code to generate the dynamic headings. I will continue to plug away with trial and error.

    Kind regards,

    Glyn

  • allanallan Posts: 48,883Questions: 1Answers: 7,122 Site admin

    That looks like all you should need for dynamic headings. Just pass your columns array into the columns option.
