Hello and thank you in advanced.

I've been trying to make a query_report on frappe.
but it doesn't return the data on the browser.
the console says 'Unable to handle success response'
console.trace() Each data element must implement a unique 'id' property
this is my sql syntax
SELECT
`tabPayment Entry`.`name` AS `id`,
`tabFees`.`student` AS `student id::100`,
`tabFees`.`student_name` AS `name::200`,

WHERE
`tabFees`.`status` = %(status)s AND

this is the screenshot of the

that sql syntax is working perfectly on the sql preview software.
Please if you have some answer i will appreciate it....
My Linq Query keeps returning the null error on FirstOrDefault
The cast to value type 'System.Int32' failed because the materialized value is null
because it can't find any records to match on the ClinicalAssetID form the ClinicalReading Table, fair enough!
But I want the fields in my details page just to appear blank if the table does not have matching entry.
But how can I handle the null issue when using the order by function ?
Current Code:
var ClinicalASSPATINCVM = (from s in db.ClinicalAssets
join cp in db.ClinicalPATs on s.ClinicalAssetID equals cp.ClinicalAssetID into AP
from subASSPAT in AP.DefaultIfEmpty()
join ci in db.ClinicalINSs on s.ClinicalAssetID equals ci.ClinicalAssetID into AI
from subASSINC in AI.DefaultIfEmpty()
join co in db.ClinicalReadings on s.ClinicalAssetID equals co.ClinicalAssetID into AR
let subASSRED = AR.OrderByDescending(subASSRED => subASSRED.MeterReadingDone).FirstOrDefault()
select new ClinicalASSPATINCVM
{
ClinicalAssetID = s.ClinicalAssetID,
AssetTypeName = s.AssetTypeName,
ProductName = s.ProductName,
ModelName = s.ModelName,
SupplierName = s.SupplierName,
ManufacturerName = s.ManufacturerName,
SerialNo = s.SerialNo,
PurchaseDate = s.PurchaseDate,
PoNo = s.PoNo,
Costing = s.Costing,
TeamName = s.TeamName,
StaffName = s.StaffName,
WarrantyEndDate = subASSPAT.WarrantyEndDate,
InspectionDate = subASSPAT.InspectionDate,
InspectionOutcomeResult = subASSPAT.InspectionOutcomeResult,
InspectionDocumnets = subASSPAT.InspectionDocumnets,
LastTypeofInspection = subASSINC.LastTypeofInspection,
NextInspectionDate = subASSINC.NextInspectionDate,
NextInspectionType = subASSINC.NextInspectionType,
MeterReadingDone = subASSRED.MeterReadingDone,
MeterReadingDue = subASSRED.MeterReadingDue,
MeterReading = subASSRED.MeterReading,
MeterUnitsUsed = subASSRED.MeterUnitsUsed,
FilterReplaced = subASSRED.FilterReplaced
}).FirstOrDefault(x => x.ClinicalAssetID == id);
Tried this but doesn't work
.DefaultIfEmpty(new ClinicalASSPATINCVM())
.FirstOrDefault()
Error was:
CS1929 'IOrderedEnumerable<ClinicalReading>' does not contain a definition for 'DefaultIfEmpty' and the best extension method overload 'Queryable.DefaultIfEmpty<ClinicalASSPATINCVM>(IQueryable<ClinicalASSPATINCVM>, ClinicalASSPATINCVM)' requires a receiver of type 'IQueryable<ClinicalASSPATINCVM>'
Feel a little closer with this but still errors
let subASSRED = AR.OrderByDescending(subASSRED => (subASSRED.MeterReadingDone != null) ? subASSRED.MeterReadingDone : String.Empty).FirstOrDefault()
Error:
CS0173 Type of conditional expression cannot be determined because there is no implicit conversion between 'System.DateTime?' and 'string'
The original error means that some of the following properties of the ClinicalASSPATINCVM class - MeterReadingDone, MeterReadingDue, MeterReading, MeterUnitsUsed, or FilterReplaced is of type int.
Remember that subASSRED here
let subASSRED = AR.OrderByDescending(subASSRED => subASSRED.MeterReadingDone).FirstOrDefault()
might be null (no corresponding record).
Now look at this part of the projection:
MeterReadingDone = subASSRED.MeterReadingDone,
MeterReadingDue = subASSRED.MeterReadingDue,
MeterReading = subASSRED.MeterReading,
MeterUnitsUsed = subASSRED.MeterUnitsUsed,
FilterReplaced = subASSRED.FilterReplaced
If that was LINQ to Objects, all these would generate NRE (Null Reference Exception) at runtime. In LINQ to Entities this is converted and executed as SQL. SQL has no issues with expression like subASSRED.SomeProperty because SQL supports NULL naturally even if SomeProperty normally does not allow NULL. So the SQL query executes normally, but now EF must materialize the result into objects, and the C# object property is not nullable, hence the error in question.
To solve it, find the int property(es) and use the following pattern inside query:
SomeIntProperty = (int?)subASSRED.SomeIntProperty ?? 0 // or other meaningful default
or change receiving object property type to int? and leave the original query as is.
Do the same for any non nullable type property, e.g. DateTime, double, decimal, Guid etc.
You're problem is because your DefaultIfEmpty is executed AsQueryable. Perform it AsEnumerable and it will work:
// create the default element only once!
static readonly ClinicalAssPatInVcm defaultElement = new ClinicalAssPatInVcm ();
var result = <my big linq query>
.Where(x => x.ClinicalAssetID == id)
.AsEnumerable()
.DefaultIfEmpty(defaultElement)
.FirstOrDefault();
This won't lead to a performance penalty!
Database management systems are extremely optimized for selecting data. One of the slower parts of a database query is the transport of the selected data to your local process. Hence it is wise to let the DBMS do most of the selecting, and only after you know that you only have the data that you really plan to use, move the data to your local process.
In your case, you need at utmost one element from your DBMS, and if there is nothing, you want to use a default object instead.
AsQueryable will move the selected data to your local process in a smart way, probably per "page" of selected data.
The page size is a good compromise: not too small, so you don't have to ask for the next page too often; not too large, so that you don't transfer much more items than you actually use.
Besides, because of the Where statement you expect at utmost one element anyway. So that a full "page" is fetched is no problem, the page will contain only one element.
After the page is fetched, DefaultIfEmpty checks if the page is empty, and if so, returns a sequence containing the defaultElement. If not, it returns the complete page.
After the DefaultIfEmpty you only take the first element, which is what you want.
In my web2py application, in the controller I read from an external DB the names of students I want to take a register for. I loop through the resulting list adding the list elements to a new list.
for student in pupils_query:
attendance_list.insert(counter, [student[0], student[1], student[2], student[3]])
counter += 1
counter = 0
Then for each student I read their attendance codes for the day so far from another table, and append them to attendance_list:
for attendance_code in attendance_result:
attendance_list[counter].append(attendance_code)
Now, I'm going to want to make a form from all this, using a table which will show each students' attendance code in a text input (so they can be updated if wrong), then have a dropdown for input of the current lesson code.
I'm using a FORM and TABLE helper to create the table in the form:
form=FORM(TABLE(*[TR(*rows) for rows in attendance_list]))
but can't seem to be able to add a new 'row' form item with something like:
select = "SELECT("+ main_reg_list +")"
attendance_list[counter].append(select)
where main_reg_list is dictionary of acceptable attendance codes (or of course, any other form input element).
In summary, I'm stuck adding new TDs to a table made with a TABLE helper from a list of lists. I bet I'm not the first person to overcome this problem.
I am still not clear about what you want. I think you want table of student information and in one column you want dropdown. Something similat to following image
Above form is created from following code.
I hope following code will help you:
# controller/default.py
def index():
# Dummy attendance list, list after appending attendance code
attendance_list = [['stud_id_1', 'first_name_1', 'last_name_1', 'attendance_code_1'],
['stud_id_2', 'first_name_2', 'last_name_2', 'attendance_code_2'],
['stud_id_3', 'first_name_3', 'last_name_3', 'attendance_code_5'],
['stud_id_4', 'first_name_4', 'last_name_4', 'attendance_code_4']]
possible_att_code = ['attendance_code_1', 'attendance_code_2', 'attendance_code_3', 'attendance_code_4', 'attendance_code_5']
# initialise form_rows with Table heading
form_rows = [THEAD(TR(TH('ID'), TH('First Name'), TH('Last Name'), TH('Attendence Code')))]
for attendance in attendance_list:
attendance_code_dropdown = _get_dropdown(attendance[0], attendance[3], possible_att_code)
td_list = [TD(attendance[0]), TD(attendance[1]), TD(attendance[2]),
TD(attendance_code_dropdown)]
table_row = TR(td_list, _id='row_' + attendance[0])
form_rows.append(table_row)
# Form submit button
form_rows.append(TR(INPUT(_type='submit')))
form = FORM(TABLE(*form_rows), _name='student_attendance',
_id='student_attendance')
if form.accepts(request, session):
# Write code to update record
pass
return dict(form=form)
def _get_dropdown(stud_id, att_code, possible_att_code):
option_list = []
for pac in possible_att_code:
if pac == att_code:
option_list.append(OPTION(pac, _value=pac, _selected='selected'))
else:
option_list.append(OPTION(pac, _value=pac))
return SELECT(*option_list, _name=stud_id)
<!-- views/default/index.html -->
{{extend 'layout.html'}}
{{=form}}
Are my assumptions correct? or you want any thing else? Comment if didn't understood code.
I am trying to add the team names(to be fetched from mongoDB) in the form to let user select the form name.
I am not getting how to add the database fetched form names in the dropdown list.
It should search based on organization_id first & then form_name.
what i am doing is this:
<?= $form->field($model1, 'form_name')->dropDownList(ArrayHelper::map(CreateTeam::find(array('organization_id' => Yii::$app->session['organization_id']))->all(), 'form_name')); ?>
It is showing me an error that missing the third argument. What could be the third argument in that case???
I went through issue with fetching record from country collection to serve record in state form
I got solution as below (considering as my state form)
use app\models\Countries;
use yii\helpers\ArrayHelper;
$countries=Countries::find()->all();
$listData=ArrayHelper::map(Countries::find()->all(),function ($model){return (string)$model->_id;},'name');
echo $form->field($model, 'countries_id')->dropDownList($listData, ['prompt'=>'Select...']);
Hope I was able to let you understand !
$collection2 = Yii::$app->mongodb->getCollection('teamdashboard');
$models = $collection2->find(array('organization_id' => Yii::$app- >session['organization_id']));
$items = ArrayHelper::getColumn($models, 'team_name');
return $this->render('teamdashboard', ['model1' => $model1, 'model2' => $model2, 'items' => $items]);
This one works fine for mongodb...
Yes, in ArrayHelper::map() first three parameters are required, so you are definitely calling this method wrong.
Check out official documentation for map().
The second parameter represents the actual values in database (usually they are primary keys), the third - readable text.
Assuming your primary key is id it should be:
$models = CreateTeam::find([
'organization_id' => Yii::$app->session['organization_id'],
])->all();
$items = ArrayHelper::map($models, 'id', 'form_name');
<?= $form->field($model1, 'form_name')->dropDownList($items) ?>
So I was advised that I could create some copy replace functionality to this form.
Here is my coding attempt in VB:
First I connect to DB using DAO. Then I use a SELECT statement that has been verified to pull the last record inserted into the DB. Then I try to refill the controls with the values from the query but I am getting reference errors.
Private Sub AutoFill_Click()
Dim db As DAO.Database, rs As DAO.Recordset
Dim strSQL As String
Set db = CurrentDb()
strSQL = "SELECT DISTINCTROW TOP 1 CPOrders.Cust, Customer.NAME, CPOrders.CP_Ref, CPOrders.Slsman, CPOrders.Date_opn, CPOrders.CPSmall, CPOrders.InvIssu, CPOrders.InvNo, CPOrders.InvDate, CPOrders.DueDate, CPOrders.ETADate, CPOrders.Closed, CPOrders.BuyerRef, CPOrders.ToCity, CPOrders.ToState, CPOrders.ToCtry, CPOrders.ToPort, CPOrders.Supplier, CPOrders.Origin, CPOrders.Product, CPOrders.GradeType, CPOrders.NoUnits, CPOrders.Pkg, CPOrders.Qty, CPOrders.TotSale, CPOrders.TotCost, CPOrders.GrMargin, CPOrders.[Sale$/Unit], CPOrders.[Cost$/Unit], CPOrders.OceanCost, CPOrders.OceanNotes, CPOrders.BLadingDate, CPOrders.USAPort, CPOrders.FOBCost, CPOrders.FASExportVal, CPOrders.InlandFrt, CPOrders.CommodCode, CPOrders.Notes FROM Customer INNER JOIN CPOrders ON Customer.[CUST_#] = CPOrders.Cust ORDER BY CPOrders.CP_Ref desc;"
Set rs = db.OpenRecordset(strSQL, dbOpenDynaset, dbReadOnly)
rs.MoveFirst
CP_Ref.ControlSource = rs!CP_Ref
Slsman.ControlSource = rs!Slsman
CPSmall.ControlSource = rs!CPSmall
InvIssu.ControlSource = rs!InvIssu
InvDate.ControlSource = rs!InvDate
DueDate.ControlSource = rs!DueDate
Closed.ControlSource = rs!Closed
rs.Close
db.Close
The control source reference picks up and autocompletes the word.
I would think that as it stands. although i'm not filling all the values with records from my SELECT statement that it would populate but instead i get things like #NAME? where the values should be. I also get a break in my code and it says "Invalid use of null"
Why? I appreciate your guys input and I can provider screenshots if necessary. I think this is involving the reference tie, but I'm not sure. Any help is much appreciated.
You are using the field names from the SELECT statement as if they were variables.
CP_Ref.ControlSource = rs("CP_Ref")
Slsman.ControlSource = rs("Slsman")
CPSmall.ControlSource = rs("CPSmall")
InvIssu.ControlSource = rs("InvIssu")
InvDate.ControlSource = rs("InvDate")
DueDate.ControlSource = rs("DueDate")
Closed.ControlSource = rs("Closed")
When you have that worked out, tackle the "Invalid use of null" problem by first identifying any fields that could potentially be NULL and using something like
SELECT Iif(IsNull([InvDate]), '', [InvDate]) As [InvDate], ...
in the SELECT statement to pass across a minimum of an empty string rather than a NULL value.
