I have this code that uses a raw SQL query inside my controller:
$sql1 = "SELECT completion_date FROM enviro_figures_upload GROUP BY YEAR(completion_date), MONTH(completion_date) DESC;";
$activeDate = $this->getDoctrine()->getManager()->getConnection()->prepare($sql1);
$activeDate->execute();
$activeDate->fetchAll();
This code then passes the data to the view which is then used in a drop down date picker. However, no results are passed to the view even though running that SQL query on the database returns the results I need. What am I missing in order to pass this data to the view?
$activeDate->execute();
$activeDate->fetchAll();
This code then passes the data to the view ...
this code doesn't pass the data to view, you have to pass the data to view by array option in render method..
something like this:
$sql1 = "SELECT completion_date FROM enviro_figures_upload GROUP BY YEAR(completion_date), MONTH(completion_date) DESC;";
$activeDate = $this->getDoctrine()->getManager()->getConnection()->prepare($sql1);
$activeDate->execute();
$result = $activeDate->fetchAll();
return $this->render('TEMPLATE_PATH', [
'result' => $result
]);

I'm trying to run a query by using a user input. The query is run in a database which has multiple columns (practically a vlookup). The query is run and the output is an array of values.
How do I get the value of only one value (scalar output to put in alert)?
Thanks
I've tried to use methods familiar to java in order to call one field in an array without any success.
i.e. output_array[0]
// define input
// var custno = app.pageFragments.Add_SalesOrder.children.Form1.children.Form1Body.children.CustomerNo_Input;
var custno = 'ENC';
// define location of output
var outputWidget = app.pageFragments.Add_SalesOrder.children.Form1.children.Form1Body.children.CustomerName_Input;
// define datasource
var datasource = app.datasources.SalesOrder;
// query
datasource.query.filters.CustomerNo._startsWith = custno.value;
// load query
datasource.load();
alert(datasource[0]);
I expect to get the first entry in the array but instead I get 'Undefined'.
If you look at the datasource documentation, you'll find out that the datasource is NOT an array, but instead an object. Since you are looking for the first result of the query, then you should access the items property of the datasource. That is an array and you can then just access the zero index of the array to get what you need.
alert(datasource.items[0]);
I have a Google drive table data source which stores list of open positions. Now in the data source I've set "Query per size" field to 10 so that I can get 10 records per page. I've added a Pager as well to show pagination.
My query is I want to display like "Page 1 of X" to my end users and this X will vary based on certain search filters. What will the best way to achieve this in Appmaker?
I've tried counting total records in a data source as per below code but every time updating that with the search criteria and recounting it is not a proper solution.
//Server side
var newQuery = app.models.Company.newQuery();
var records = newQuery.run();
var totalCount =0;
for(var i=0;i<records.length;i++)
{
totalCount=totalCount+1;
}
return totalCount;
In case you don't have any filters in your table your server code can be as simple as
// Server script
function getPagesCount(pageSize) {
var recordsCount = app.models.MyModel.newQuery().run().length;
var pagesCount = Math.ceil(recordsCount / pageSize);
return pagesCount;
}
As an alternative you can consider creating Calculated Model with a single field PagesCount.
In case you have some filters associated with the table then you'll need to run the query for the pages number with exact same filters.
Most likely the entire setup will not work effectively with Drive Tables since there is no way to query records number without querying records themselves. With Cloud SQL data backend one can create Calculated SQL Model with lightweight native SQL query (here :PageSize is query parameter which should be equal to the query.limit of the actual datasource):
SELECT
Ceil(COUNT(1) / :PageSize) AS RecordsNumber
FROM
TableName
WHERE
...
I've achieved this using Calculated Model as suggested by Pavel.
Steps :
Create a calculated data source with one field count.
In that data source add one parameter searchQuery. This will contain users filter going forward. Currently I have only one search query in which user can search many things. So I've added one parameter only.
In this data source add following server script.
Code:
// Server script
function getTotalRecords(query) {
var receivedQuery = query.parameters.searchQuery;
// console.log('Received query:' + query.parameters.searchQuery);
var records = app.models.Company.newQuery();
records.parameters.SearchText = query.parameters.searchQuery;
if(receivedQuery !== null) {
records.where = '(Name contains? :SearchText or InternalId contains? ' +
':SearchText or LocationList contains? :SearchText )';
}
var recordsCount = records.run().length;
var calculatedModelRecords = [];
var draftRecord = app.models.RecordCount.newRecord();
draftRecord.count = ''+recordsCount;
calculatedModelRecords.push(draftRecord);
return calculatedModelRecords;
}
.
On the Appmaker page bind a label with this data source.
On search query/your filter applied event add following code which Reload this data source and assign value to Parameter.
// Client script
function updateRecordCount(newValue) {
var ds = app.datasources.RecordCount;
ds.query.parameters.searchQuery = newValue;
ds.unload();
ds.load();
}
I have a Calculated Model, MonthlyTotalsByResource, displayed in a table that I am trying to query with a filter. First, I am retrieving the initial data from a regular Data Model called Allocations. I only wish to retrieve records from Allocations where the "Approved" field =true.
I also want to allow the user to filter MonthlyTotalsByResource by the "ManagerName" field. I have created a Dropdown widget with the Options as the full list of managers, and the Value is a query on the Calculated Model datasource:
#datasource.query.filters.ManagerName._equals
Here is the beginning of my code for getting the data for the Calculated Model MonthlyTotalsByResource from the regular data model Allocations, and where I filter for only "true" values in the Approved field. I am unclear what I should make the ManagerName filter set to in order for it to be binded to my Dropdown widget, or if I should add another query on the Calculated Model itself, instead of here on the regular Data Model.
function getMonthlyTotalsByResource_() {
var allRecordsQuery = app.models.Allocations.newQuery();
allRecordsQuery.filters.Approved._equals = true;
allRecordsQuery.filters.Resource.Manager.ManagerName._equals = ;
First things first, you need to introduce ManagerName parameter in your calculated datasource:
Once you add the parameter, you'll be able to set its value on client and read on server.
// dropdown widget's 'value' property binding
#datasources.MonthlyTotalsByResource.query.parameters.ManagerName
// server side code to get parameter value
var query = app.models.Allocations.newQuery();
...
query.filters.Resource.Manager.ManagerName._equals = query.parameters.ManagerName;

I have a model named EmailDetailModel with a Dictionary field.
My query is:
var query = from email in context.EmailModel
where rolesForUser.Contains(email.GroupName)
orderby email.Id descending
select new EmailDetailModel()
{
From = email.From,
Id = email.Id,
message = email.Body,
subject = email.Subject,
pathFileName =
(from pdf in context.PdfModel
where pdf.Email_Id == email.Id
select pdf)
.ToDictionary(k => k.PathFile, v => v.FileName),
timeSend = email.ActiveTime};
However an error occurs on this line when trying to send the list to the view:
View(query.ToPagedList(pageNumber, pageSize));
Saying that:
LINQ to Entities does not recognize the method 'System.Collections.Generic.Dictionary
If anybody could help me, I'm not sure how I can pass the key and value into my pathFileName Dictionary.
The issue likely is that there is no SQL like conversion of the dictionary generation that LINQ to Entities can understand.
I have struggled with similar error messages whenever LINQ cannot be translated to a SQL statement.
I've got a backbone collection and I'm trying to filter by an id within the attributes
basically, a user has classes, and the class has a location_id, and I want to filter by the location id. My collection looks like this to give you an idea.
-user
-models
-0
-attributes
-location_id
-1
-attributes
-location_id
-2
-attributes
-location_id
I thought I could filter this by using
var get_locations = user_class_collection.filter(function(classes){
console.log(classes);
return classes.get(location_id)==location.id;
});
console.log(get_locations);
but that is returning an empty array, when I know the location_id is in the collection.
Any idea why this isn't working? I've also tried to grab classes.attributes.get, but it wasn't any better
In the first few responses, it was properly mentioned that I had to quote the get('location_id'). I've now done that, but unfortunately, I'm still getting an empty array. I thought that the filter would loop through the classes and I would get a console output for each class, but the console.log(classes) is only getting triggered once. Is that a hint? Or a red-herring?
you are trying to get a property from classes that is named as the value of the location_id parameter
you should instead make that a string (in fact you can choose how you make it a string, single or double quotes both work)
user_class_collection.filter(function(classes){
return classes.get('location_id') == location.id;
});
For filtering collection using backbone the best approach is to use a filtered function in your collection
var UserCollection = Backbone.Collection.extend ({
filtered : function ( id ) {
I suggest to use UnderScore filter which will return true for valid and false for invalid where true is what you are looking for. use this.models to get the current collection models use model.get( '' ) to get the element you want to check for
var results = _.filter( this.models, function ( model ) {
if ( model.get('location_id') == id )
return true ;
return false ;
});
Then use underscore map your results and transform it to JSON like
results = _.map( results, function( model ) { return model.toJSON() } );
Finally returning a new backbone collection with only results
return new Backbone.Collection( results ) ;
Optionally if you don't want to keep all the data in the collection but just the filtered one you should reset the collection and skip the above return like
this.reset( results ) ;
View call the filtered collection and the render the result
Try this:
user_class_collection.select(function(classes){
return classes.get("location_id")==location.id;
});
