While working on report for some client, guys and me, we've succeeded to define(Java), populate(from Hibernate v3.x) and 'feed' custom data source (in pseudo raw SQL something like:
select t1.c1,t2.c2,t3.c3 ... join-join-join ...
)
to
JasperFillManager(API v3.6.7):
ds = JasperFillManager.fillReport(fillReport(java.lang.String sourceFileName,
java.util.Map params, JRDataSource myCustomDataSource);
Now the BIG issue comes when we trying with iReport (v4.0.2) to populate this custom data source into report(either sub-report).
We've tried to pass it as parameter, as single data source to fillReport() - nAdA. Help please.
Now at all, conceptualy or by example, how to pass number if different custom data sources into sub-reports. Example could be very helpful.
Appreciate the help,

I am desperately waiting for someone attention to get my question answered.... please help..
ModelAdmin model has to export to Excel action method.
I need to access related model fields in action method. That means I can not pass any arguments therefore I tried relatedmodel_set but ModelAdmin action method shows memory location and fails when I try to access values through attributes:
<django.db.models.fields.related_descriptors.create_reverse_many_to_one_manager..RelatedManager object at 0x7f8eea904ac0>
model.py
class EnrolStudent(models.Model):
def get_trn_activity(self):
return self.studenttraininactivities_set
class StudentTraininActivities(models.Model):
trainin_activities = models.ForeignKey(EnrolStudent,
on_delete=CASCADE, null=True )
<other fields...>
admin.py
#admin.register(EnrolStudent)
class EnrolAdmin(admin.ModelAdmin):
form = CityInlineForm
inlines = [CohortTraininActivitiesInline]
...
actions = [export_as_txt_action_0120("File NAT00120 data Export"
, fields=['information_no', 'get_trn_activity',
'student_enrol__student_code'])]
I need to access related model fields to export to excel.
I can not pass parameter to get_trn_activity as you have noticed.
Therefore selected rows only data from Django admin change_list page will only need bit of work using its queryset in actions method used in separate actions.py file that I can do!
Please help me with this issue. I am new to Python / Django.
I also tried property decorator in related model then access in a method in main model then call it inside action but same problem with memory address not the direct value and then how to get data of memory location here .... I don't know.
If I can access the related fields then I can do it no issue.
Another question:
I had same situation with model/related model before, but they were connected through OneToOneField relationship and I was able to use dundor to access related model fields but in this case of ForiegnKey relationship I can not see related model in queryset.
In other case this is what I can do easily; here cohortdetails is related model and when I debug I saw it was listed in queryset that was great.
actions = [export_as_txt_action_0080("File NAT00080 txt Export",
fields=['rto_student_code', 'first_name', 'family_name'
,'cohortdetails__highest_school__highestschool_levelcode',
'cohortdetails__cohort_gender'
, 'cohortdetails__student_dob' ])]
I hope there is someone with experience in citrus :)
I've written a citrus (1.4 and 2.3) DB test against an Oracle db.
In citrus you can pass your query either as String or by referencing a file resource.
The String option works fine and the validation succeeds:
oracle.jdbc.pool.OracleDataSource ds = new oracle.jdbc.pool.OracleDataSource();
//init ds ...
query(ds).statement("SELECT * FROM TOUR WHERE ID = 12345").validate("STATUS", "1");
However the Resource option fails:
oracle.jdbc.pool.OracleDataSource ds = new oracle.jdbc.pool.OracleDataSource();
//init ds ...
query(ds).sqlResource("classpath:testdata/template/dbQuery.sql").validate("STATUS", "1");
Debugging the code showed that Citrus expects all statements in the sqlResource file to be separated by ";".Then it will correctly create separate statements and will try to execute them. However executing statements ending in ";" results in "SQLSyntaxErrorException: ORA00911: invalid character".
So am I missing something here?
Consider this to be a bug, issue has been opened (https://github.com/christophd/citrus/issues/79)
Issue has been fixed with 2.5.2 release of Citrus
I have SQL Server 2008 with SSRS installed on one server and SQL Server 2008 R2 with SSRS installed on a new server. I want to migrate 200+ reports as well as a few shared schedules and a couple data sources from the first server to the second one using the SSRS web service API. For simplicity sake since there are only a couple of shared data sources I went ahead and created those using the Report Manager interface.
Unfortunately, those who came before me embedded the data source information in each report (connection string, login, password, etc). I thought this would be a great time to change these to point to the shared data source so this would not have to be done for each report, one by one. I can create the reports on the new server just fine using CreateCatalogItem but I can't seem to determine how to properly go about changing from an embedded data source to a shared data source.
So far I have tried both SetItemReferences:
itemRef.Reference = "/Data Sources/TMS";
itemRef.Name = "TMS";
itemRef.Reference = "/Data Sources/TMS";
rs2010.SetItemReferences(catItem.Path, new ReportService2010.ItemReference[] { itemRef });
and SetItemDataSources:
ReportService2010.DataSourceReference dataSourceRef = new ReportService2010.DataSourceReference();
dataSourceRef.Reference = "/Data Sources/TMS";
ReportService2010.DataSource dataSource = new ReportService2010.DataSource();
dataSource.Name = "TMS";
dataSource.Item = dataSourceRef;
rs2010.SetItemDataSources(catItem.Path, new ReportService2010.DataSource[] { dataSource });
Both methods result in a "NotFoundException" when attempted on a report with an embedded data source but they both work just fine on reports that are already pointing to a shared data source.
Furthermore, I have searched all over Google as well as StackOverflow for a solution but have found nothing. Can anyone point me in the right direction here?
So I kept working with the SetItemReferences method and had a brilliant idea that ended up working. The final code I used is below:
List<ReportService2010.ItemReference> itemRefs = new List<ReportService2010.ItemReference>();
ReportService2010.DataSource[] itemDataSources = rs2010.GetItemDataSources(catItem.Path);
foreach (ReportService2010.DataSource itemDataSource in itemDataSources)
{
ReportService2010.ItemReference itemRef = new ReportService2010.ItemReference();
itemRef.Name = itemDataSource.Name;
itemRef.Reference = "/Data Sources/TMS";
itemRefs.Add(itemRef);
}
rs2010.SetItemReferences(catItem.Path, itemRefs.ToArray());
The problem was that I was not using the same DataSource name as what was found in the report .rdl file. I was able to determine what the name should be using the GetItemDataSources method. Since this method returns an array and may have more than one item in said array, I looped through it to create multiple ItemReferences if more than one existed though I doubt that happens very often if at all.
I am using smart gwt 2.5 List grid.
In this I am using check box for simple selection.below is the code for that:
getGrid().setSelectionAppearance(SelectionAppearance.CHECKBOX);
getGrid().setSelectionType(SelectionStyle.SIMPLE);
I am using data source for the list grid.For feeding data calling this method:
public void setTestData(DataClass[] testData) {
setAttribute("testData", testData, true);
}
My grid is rendering data properly.Now I want to set checked some of records (Row) depending in some condition.Lets say I want row number 1 and 5 should be checked.
For this after feeding data to data source I write code like below to check data:
getGrid().selectRecord(1);`
getGrid().selectRecord(5);
But is not doing any checked operations to check box.I am not getting at what point I am doing mistake.
same thing when I tried with out data source and I feed data to list grid simply by setdata It was working.
Please help me out.Thanks in advance
When you use a DataSource, including a clientOnly DataSource, fetching data is asynchronous, so your selectRecord() calls are happening when data is not loaded yet. Wait for DataArrived before attempting to select records.
One work around which is working for me is that:
I removed selection appearance and selected type from my grid and took a column for check box
like below:
NTListGridField customCheckBoxField = new NTListGridField("select", "Select", 25);
customCheckBoxField.setAlign(Alignment.LEFT);
customCheckBoxField.setType(ListGridFieldType.BOOLEAN);
customCheckBoxField.setCanFilter(false);
customCheckBoxField.setCanEdit(true);
customCheckBoxField.setCanToggle(true);
Now for selecting records,
record.setAttribute("select", true);
I've been looking on forums for 2 days now and can't find a good answer so I'll just post it.
I appear to be having a problem posting JSON back to the controller to save. The JSON should map to model view but it keeps getting default(constructor)values rather then the values from the POST.
We have a series of JS widgets that contain a data field with json in them. We do all our data manipulation in these widget objects on the client side. When a user wants to save we grab the data we need from the widgets involved and we put it into another JSON object that matches a ViewModel and POST that back to the server.
For example:
$("#Save").click(function () {
if (itemDetails.preparedForSubmit() && itemConnections.preparedForSubmit()) {
itemComposite.data.Details = itemDetails.data;
itemComposite.data.Connections= itemConnections.data;
$.post(MYURL, itemComposite.data);
} else {
alert("failed to save");
}
});
The preparedForSubmit() method simple does stuff like any validation checks or last minute formatting you might need to do client side.
The itemDetails widgets data matches a ViewModel.
The itemConnections widgets data matches a collection of ViewModels.
The Controller looks like this:
[HttpPost]
virtual public JsonResult SaveItemDetailsComposite(ItemComposite inItemData)
{
if (ModelState.IsValid)
{
try
{
_Mapper.Save(itemComposite.Details , itemComposite.Connections);
return Json(true);
}
catch (Exception ex)
{
_log.Error("Exception " + ex.InnerException.Message);
throw;
}
}
return Json(SiteMasterUtilities.CreateValidationErrorResponse(ModelState));
}
The ItemComposite Class is a simple View Model that contains a single itemDetails object and a collection of itemConnections. When it returns data to here it is just getting the default data as if it got a new ItemComposite rather than converting the POST data.
in Firebug I see the data is posted. Although it looks weird not automatically formatted in firebug.
Are you saying that itemComposite.data is formatted as a JSON object? If so, I'm pretty sure you're going to have to de-serialize it before you can cast it to your object. Something like:
ItemComposite ic = jsSerializer.Deserialize<ItemComposite>(this.HttpContext.Request.Params[0]);
You may want to look into a framework like JSON.NET to ensure that your data is being serialized properly when it gets supplied to your Action.
JSON.NET seems like it's one of the main stream frameworks: http://json.codeplex.com/releases/view/43775
Hope this helps.

You could also use the JSON Serializer in WCF: http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer.aspx
SO wouldn't let me put both links in one answer, sorry for the split answer.
Thanks everyone. I think I have solved my problem and I'm pretty sure that I had four issues. For the most part I followed thatSteveguys's suggestion and read more on this article: http://haacked.com/archive/2010/04/15/sending-json-to-an-asp-net-mvc-action-method-argument.aspx
Using jQuery's post() method and specifying json as the type didn't seem to actually send it as json. By using the ajax() method and specifying json it sent it as json.
The JSON.serialize() method was also need to cleanly send over the json.
Also my ViewModel design was a big problem. We are using the MS code analytic build junk and it didn't want me having a setter for my collections in the ViewModel. So me being from a java/hibernate world, thought it didn't need them to bind and it would just come in as a serialized object magically. Once I just suppressed the error and reset up my setters. I am getting the collections now in my controller.
I believe using the MVC2 Future's Value Providers are doing something but it still doesn't convert json dates robustly, So I am still investigating the best way to do that.
I hope my issues help out others.
UPDATE: using this method to update collections of data appears to be super slow. A collection with 200 entries in it and 8 fields per entry takes 3 minutes to get to the controller. Just 1 or 2 entries take very little time. The only thing I know of that is happening between here is data binding to the model view. I don't know if MVC2 provides a easy way to send this much data and bind it.
