I am trying to add columnSummary to my table using Handsontable. But it seems that the function does not fire. The stretchH value gets set and is set properly. But it does not react to the columnSummary option:
this.$refs.hot.hotInstance.updateSettings({stretchH: 'all',columnSummary: [
{
destinationRow: 0,
destinationColumn: 2,
reversedRowCoords: true,
type: 'custom',
customFunction: function(endpoint) {
console.log("TEST");
}
}]
}, false);
I have also tried with type:'sum' without any luck.
Thanks for all help and guidance!
columnSummary cannot be changed with updateSettings: GH #3597
You can set columnSummary settings at the initialization of Handsontable.
One workaround would be to somehow manage your own column summary, since Handsontable one could give you some headeache. So you may try to add one additional row to put your arithmetic in, but it is messy (it needs fixed rows number and does not work with filtering and sorting operations. Still, it could work well under some circumstances.
In my humble opinion though, a summary column has to be fully functionnal. We then need to set our summary row out of the table data. What comes to mind is to take the above mentioned additional row and take it away from the table data "area" but it would force us to make that out of the table row always looks like it still was in the table.
So I thought that instead of having a new line we could just have to add our column summary within column header:
Here is a working JSFiddle example.
Once the Handsontable table is rendered, we need to iterate through the columns and set our column summary right in the table cell HTML content:
for(var i=0;i<tableConfig.columns.length;i++) {
var columnHeader = document.querySelectorAll('.ht_clone_top th')[i];
if(columnHeader) { // Just to be sure column header exists
var summaryColumnHeader = document.createElement('div');
summaryColumnHeader.className = 'custom-column-summary';
columnHeader.appendChild( summaryColumnHeader );
}
}
Now that our placeholders are set, we have to update them with some arithmetic results:
var printedData = hotInstance.getData();
for(var i=0;i<tableConfig.columns.length;i++) {
var summaryColumnHeader = document.querySelectorAll('.ht_clone_top th')[i].querySelector('.custom-column-summary'); // Get back our column summary for each column
if(summaryColumnHeader) {
var res = 0;
printedData.forEach(function(row) { res += row[i] }); // Count all data that are stored under that column
summaryColumnHeader.innerText = '= '+ res;
}
}
This piece of code function may be called anytime it should be:
var hotInstance = new Handsontable(/* ... */);
setMySummaryHeaderCalc(); // When Handsontable table is printed
Handsontable.hooks.add('afterFilter', function(conditionsStack) { // When Handsontable table is filtered
setMySummaryHeaderCalc();
}, hotInstance);
Feel free to comment, I could improve my answer.
I know there are many solutions provided regarding multiple insertion in sqlite3 but I am looking for efficient method in which data is getting inserted into two tables and data of second table is dependent on first table. This is a node js application.
I have two tables programs and tests in sqlite3. Table tests contains id of programs i.e. one program can contains multiple tests.
The suggested method on official page of sqlite3 module is as follows:
var sqlite3 = require('sqlite3').verbose();
var db = new sqlite3.Database(':memory:');
db.serialize(function() {
db.run("CREATE TABLE lorem (info TEXT)");
var stmt = db.prepare("INSERT INTO lorem VALUES (?)");
for (var i = 0; i < 10; i++) {
stmt.run("Ipsum " + i);
}
stmt.finalize();
db.each("SELECT rowid AS id, info FROM lorem", function(err, row) {
console.log(row.id + ": " + row.info);
});
});
db.close();
As In my requirement I have to insert data in tow tables so I am using the following code:
var programData = resp.program_info; // contains complete data of programs and tests
db1.run("INSERT INTO programs (`parent_prog_id`, `prog_name`, `prog_exercises`, `prog_orgid`, `prog_createdby`, `prog_created`, `prog_modified`, `prog_status`) VALUES (?,?,?,?,?,?,?,?)",prog.parent_program_id,prog.programName, JSON.stringify(prog), req.session.org_id, prog.created_by, prog.created_at, prog.updated_at, prog.program_status,function(err){
if(err){
throw err;
}else{
var count = 1;
var step2PostedData = prog;
for (i in step2PostedData.testsInfo) {
var c = 0;
for(j in step2PostedData.testsInfo[i]){
var obj = Object.keys(step2PostedData.testsInfo[i])[c];
db1.prepare("INSERT INTO `tests` ( `parent_name`,`test_name`, `test_alias`, `sequences`, `duration`, `prog_id`, `org_id`, `test_createdby`, `test_created`, `test_modified`, `test_status`) VALUES(?,?,?,?,?,?,?,?,?,?,?)")
.run(count, obj,
step2PostedData.testsInfo[i][j].alias,
step2PostedData.testsInfo[i][j].sequences,
step2PostedData.testsInfo[i][j].duration,
this.lastID, // using this I am getting program id
req.session.org_id,
prog.created_by,
prog.created_at,
prog.updated_at,
prog.program_status);
c++;
count++;
}
}
Now, my query is If I am using the suggested method then I am not getting last inserted program id from programs table. without callback.
e.g. If I use the following code;
var stmt = db1.prepare("INSERT INTO programs (`parent_prog_id`, `prog_name`, `prog_exercises`, `prog_orgid`, `prog_createdby`, `prog_created`, `prog_modified`, `prog_status`) VALUES (?,?,?,?,?,?,?,?)";
var stmt2 = db1.prepare("INSERT INTO `tests` ( `parent_name`,`test_name`, `test_alias`, `sequences`, `duration`, `prog_id`, `org_id`, `test_createdby`, `test_created`, `test_modified`, `test_status`) VALUES(?,?,?,?,?,?,?,?,?,?,?)")
programData.forEach(function(prog){
// Inserts data in programs table
stmt.run(prog.parent_program_id,prog.programName, JSON.stringify(prog), req.session.org_id, prog.created_by, prog.created_at, prog.updated_at, prog.program_status);
for (i in step2PostedData.testsInfo) {
var c = 0;
for(j in step2PostedData.testsInfo[i]){
var obj = Object.keys(step2PostedData.testsInfo[i])[c];
stmt2.run(
count,
obj,
step2PostedData.testsInfo[i][j].alias,
step2PostedData.testsInfo[i][j].sequences,
step2PostedData.testsInfo[i][j].duration,
'what should be there',// How to get last program inserted ID there
req.session.org_id,
prog.created_by,
prog.created_at,
prog.updated_at,
prog.program_status);
} // inner for loop ends
} // outer for loop ends
stmt.finalize();
stmt2.finalize();
});
If I use this.lastID that returns null, obviously as no callback is
now.
If I use sqlite3_last_insert_rowid() then
sqlite3_last_insert_rowid is not defined error.
If I use last_insert_rowid() then last_insert_rowid() is not
defined.
Query:
How can I insert last inserted program id there, Currently I am getting last program id as null?
Edit:
If and only if using callback is the way or method to get the last ID then I will keep my code running as it is currently. Can anyone please suggest how can I increase the speed of insertion.
Thank you!
sqlite3_last_insert_rowid() is a part of the C API.
last_insert_rowid() is an SQL function.
If the documentation tells you that lastID is valid inside the callback, then you must use the callback.
Just move all the child INSERTs into the completion callback of the parent INSERT.
(The suggested code is not intended to show how to get the last inserted ID; it just demonstrates that the values actually have been inserted.)
So I have a standard service reference proxy calss for MS CRM 2013 (i.e. right-click add reference etc...) I then found the limitation that CRM data calls limit to 50 results and I wanted to get the full list of results. I found two methods, one looks more correct, but doesn't seem to work. I was wondering why it didn't and/or if there was something I'm doing incorrectly.
Basic setup and process
crmService = new CrmServiceReference.MyContext(new Uri(crmWebServicesUrl));
crmService.Credentials = System.Net.CredentialCache.DefaultCredentials;
var accountAnnotations = crmService.AccountSet.Where(a => a.AccountNumber = accountNumber).Select(a => a.Account_Annotation).FirstOrDefault();
Using Continuation (something I want to work, but looks like it doesn't)
while (accountAnnotations.Continuation != null)
{
accountAnnotations.Load(crmService.Execute<Annotation>(accountAnnotations.Continuation.NextLinkUri));
}
using that method .Continuation is always null and accountAnnotations.Count is always 50 (but there are more than 50 records)
After struggling with .Continutation for a while I've come up with the following alternative method (but it seems "not good")
var accountAnnotationData = accountAnnotations.ToList();
var accountAnnotationFinal = accountAnnotations.ToList();
var index = 1;
while (accountAnnotationData.Count == 50)
{
accountAnnotationData = (from a in crmService.AnnotationSet
where a.ObjectId.Id == accountAnnotationData.First().ObjectId.Id
select a).Skip(50 * index).ToList();
accountAnnotationFinal = accountAnnotationFinal.Union(accountAnnotationData).ToList();
index++;
}
So the second method seems to work, but for any number of reasons it doesn't seem like the best. Is there a reason .Continuation is always null? Is there some setup step I'm missing or some nice way to do this?
The way to get the records from CRM is to use paging here is an example with a query expression but you can also use fetchXML if you want
// Query using the paging cookie.
// Define the paging attributes.
// The number of records per page to retrieve.
int fetchCount = 3;
// Initialize the page number.
int pageNumber = 1;
// Initialize the number of records.
int recordCount = 0;
// Define the condition expression for retrieving records.
ConditionExpression pagecondition = new ConditionExpression();
pagecondition.AttributeName = "address1_stateorprovince";
pagecondition.Operator = ConditionOperator.Equal;
pagecondition.Values.Add("WA");
// Define the order expression to retrieve the records.
OrderExpression order = new OrderExpression();
order.AttributeName = "name";
order.OrderType = OrderType.Ascending;
// Create the query expression and add condition.
QueryExpression pagequery = new QueryExpression();
pagequery.EntityName = "account";
pagequery.Criteria.AddCondition(pagecondition);
pagequery.Orders.Add(order);
pagequery.ColumnSet.AddColumns("name", "address1_stateorprovince", "emailaddress1", "accountid");
// Assign the pageinfo properties to the query expression.
pagequery.PageInfo = new PagingInfo();
pagequery.PageInfo.Count = fetchCount;
pagequery.PageInfo.PageNumber = pageNumber;
// The current paging cookie. When retrieving the first page,
// pagingCookie should be null.
pagequery.PageInfo.PagingCookie = null;
Console.WriteLine("#\tAccount Name\t\t\tEmail Address");while (true)
{
// Retrieve the page.
EntityCollection results = _serviceProxy.RetrieveMultiple(pagequery);
if (results.Entities != null)
{
// Retrieve all records from the result set.
foreach (Account acct in results.Entities)
{
Console.WriteLine("{0}.\t{1}\t\t{2}",
++recordCount,
acct.EMailAddress1,
acct.Name);
}
}
// Check for more records, if it returns true.
if (results.MoreRecords)
{
// Increment the page number to retrieve the next page.
pagequery.PageInfo.PageNumber++;
// Set the paging cookie to the paging cookie returned from current results.
pagequery.PageInfo.PagingCookie = results.PagingCookie;
}
else
{
// If no more records are in the result nodes, exit the loop.
break;
}
}
In real project, TEST_TABLE would contain much of TEST_TABLE_NESTED, each with its own testVariable and bunch of testScript. test function from testScript would be used in C++ code, and TEST_TABLE_NESTED tables would be added automatically from C++ code too.
TEST_TABLE =
{
TEST_TABLE_NESTED =
{
testVariable = 5,
testScript =
{
test = function()
print(testVariable, "hello") --How to access 'testVariable'?
end
}
}
}
EDIT :
This is the actual scenario of using this script:
GameObjectScriptTables =
{
GameObject_1 = --Container of scripts corresponding to some gameObject
{
gameObjectOwner = actual_object_passed_from_c++, --This is an actual object passed from c++
GameObjectScript_1 = --This is a script with update(dt) method which will be called somwhere in c++ code
{
update = function(dt)
--here I want to use some data from gameObjectOwner like position or velocity
end
}
}
GameObject_2 =
{
gameObjectOwner = actual_object_passed_from_c++,
GameObjectScript_1 =
{
update = function(dt)
--here I want to use some data from gameObjectOwner like position or velocity
end
},
GameObjectScript_2 =
{
update = function(dt)
--here I want to use some data from gameObjectOwner like position or velocity
end
}
}
--And so on
}
Idea is that exists some testVariable object (passed from C++), which data is used all over TEST_TABLE_NESTED. For me, above example looks natural for this task, but it prints nil instead of 5. So how to acces a testVariable from testScript without printing a full path like TEST_TABLE.TEST_TABLE_NESTED.testVariable?
You're asking for something like a "parent" pointer, which tells table B about table A, but that doesn't exist. Internally, the only association they have is that one of A's values happens to be B, but any number of tables could contain B as a value. Which is B's parent?
If you want B to know about A, you'll need to tell it. You can add an extra parameter to update which receives the game owner object, or update can be a closure which contains the game owner as a bound variable, so on and so forth.
I made it work by providing a gameObjectOwner instance for each GameObjectScript_N. However I don't know is it expensive solution or not.
I am looking for a way to return the value of a precise column in the first result of a query.
The query result contains always 1 row containing the following columns :
ID
PW
RANK
I am trying to only get the rank value in order to push it into a session variable.
I tried messing with :
$row-> $query->row();
But then I don't know how to get only the value of the rank column. Ideally, I would want to get that value, then return it to allow my controller to set it in the session variable ( doing it in the model would be easier but would break the MVC pattern, right ?)
How can I do this ?
Thanks
Have the controller call a function in the model that return that value. Let's say the model has a function name get_rank()
public function get_rank($id)
{
// assumes your ID is an int
$id = (int)$id;
// avoid wasting a query
if ($id < 1) return FALSE;
// build query
$this->db->select('rank');
$this->db->from('YOUR_TABLE');
$this->db->where('id', $id);
// maybe some sorting / limiting here if you need it
// get result
$rs = $this->db->get();
if ($rs->num_rows() > 0)
{
// just get the first row
$row = $rs->row();
return $row->rank;
}
return FALSE;
}
