Translation model in App Maker - google-app-maker

I would to make the field descriptions and label texts in my pages multi-lingual. Originally they are in English and I could let the user translate them through Google Translate. In order to avoid translation errors I would like to implement a translation data model that contains
FieldDisplayName / LabelText
FieldDisplayName_DE
FieldDisplayName_FR
FieldDisplayName_IT
etc.
All the pages contain a page header fragment that contains a menu button, searchbox etc. like in the Starter App template. I am planning on integrating a dropdown widget in the page header that allows to choose between the languages (DE,EN,FR,IT,...). Is it possible to bind the display name to the user's selection? How would I have to implement that?

The easiest way (to implement/use/maintain) that would provide highest possible translation quality will be introducing Translation data model with the following structure:
+----+--------+------------+------------+------------+-----+
| Id | Locale | FirstName | LastName | Age | ... |
+----+--------+------------+------------+------------+-----+
| 1 | EN | First name | Last name | Age | ... |
+----+--------+------------+------------+------------+-----+
| 2 | RU | Имя | Фамилия | Возраст | ... |
+----+--------+------------+------------+------------+-----+
| 3 | DE | Voornaam | Achternaam | Leeftijd | ... |
+----+--------+------------+------------+------------+-----+
| 4 | ... | ... | .... | ... | ... |
+----+--------+------------+------------+------------+-----+
In this model every column represents unique label within your app and every row represents labels's translations for supported languages. This model can be easily used in label bindings:
#datasources.UserTranslations.item.FieldNameToTranslate
Maintaining these translation will be easy as well, just drag and drop editable table on UI.
Here is a query script for the UserTranslations datasource:
// Assuming that you already have robust user settings implementation.
var userSettings = getUserSettings_();
var query = app.models.Translation.newQuery();
query.filters.Locale._equals = userSettings.Locale;
return query.run();
Radically different implementation will be
Introducing Calculated Model with the same set of fields as in the previous approach
Using Model Metadata API to extract display names from the model's fields
Translate fields using Translate API
Populate calculated model record with translated values
Here is super high level server pseudo script for that flow:
var userLocale = getUserLocaleFromUserSettings();
var fieldsDisplayNames = getFieldsDisplayNames(app.models.Translation);
var translations = translate(fieldsDisplayNames, 'en', userLocale);
var record = app.models.Translation.newRecord();
mapRecordFieldsToTranslations(record, translations);
return [record];

After some trials a translation model turned out to be too laggy for my demands. Therefore I have hardcoded the binding expression into the labels I want to translate. The binding expression looks a little bit like this:
(#pages.UserSettings.LanguageDropdown.value == 'EN') ? 'Contact' : 'Kontakt'

Aggregate values from customMeasurements column

For my company I need to extract data from Azure Application Insights.
All the relevant data is stored in the customMeasurements. Currently, the table looks something like this:
name | itemType | customMeasurements
-----------------------------------------------------------
AppName | customEvent | {
Feature1:1,
Feature2:0,
Feature3:0
}
-----------------------------------------------------------
AppName | customEvent | {
Feature1:0,
Feature2:1,
Feature3:0
}
I'm trying to find a Kusto query which will aggregate all enabled features (which would have a value of '1'), but I'm unable to do so.
I tried several things to get this resolved like the following:
customEvents
| extend test = tostring(customMeasurements.["Feature2"])
| summarize count() by test
This actually showed me the number rows that have Feature2 set to '1' but I want to be able to extract all features that have been enabled without specifying them in the query (as they can have custom names).
Could somebody point me in the right direction please
perhaps, something like the following could give you a direction:
datatable(name:string, itemType:string, customMeasurements:dynamic)
[
'AppName', 'customEvent', dynamic({"Feature1":1,"Feature2":0,"Feature3":0}),
'AppName', 'customEvent', dynamic({"Feature1":0,"Feature2":1,"Feature3":0}),
]
| mv-apply customMeasurements on
(
extend feature = tostring(bag_keys(customMeasurements)[0])
| where customMeasurements[feature] == 1
)
| summarize enabled_features = make_set(feature) by name

series_fir not generating moving average on application insights chart

Given the following Kusto query:
range t from bin(now(), 1h)-23h to bin(now(), 1h) step 1h
| summarize t=make_list(t)
| project id='TS', val=dynamic([0,0,0,0,0,0,0,0,0,10,20,40,100,40,20,10,0,0,0,0,0,0,0,0]), t
| extend 5h_MovingAvg=series_fir(val, dynamic([1,1,1,1,1])),
5h_MovingAvg_centered=series_fir(val, dynamic([1,1,1,1,1]), true, true)
| render timechart
I am unable to get application insights to actually draw the moving average lines shown in this document
I have also tried applying the article to one of our actual applications and have not had any luck either. There are no errors or anything that would give a clue as to why the moving averages are not being drawn. I'm assuming there is a setting somewhere that most probably has to be set. Here is my custom query:
let timeGrain=1d;
let ago = ago(7d);
let mAvgParm = repeat(1, 5);
let dataset=requests
// additional filters can be applied here
| where timestamp >= ago and cloud_RoleName == "recalculateordercombination" and resultCode == 500
| where client_Type != "Browser" ;
// calculate failed request count for all requests
dataset
| make-series dailyFailure=sum(itemCount) default=0 on timestamp in range(ago, now(), timeGrain) by resultCode
// render result in a chart
| extend SMA = series_fir(dailyFailure, mAvgParm)
| render timechart
What are these queries missing in order to draw the moving average lines using series_fir?

The web clients for both services are different, and that's also true for their rendering logic.
In Azure Data Explorer (Kusto), you can just use render timechart on time-series data (which is typed as dynamic).
In other cases, you may need to first mv-expand the series (link to doc), before rendering it.
Here's an example which matches the first query in your question:
range t from bin(now(), 1h)-23h to bin(now(), 1h) step 1h
| summarize t=make_list(t)
| project id='TS', val=dynamic([0,0,0,0,0,0,0,0,0,10,20,40,100,40,20,10,0,0,0,0,0,0,0,0]), t
| extend 5h_MovingAvg=series_fir(val, dynamic([1,1,1,1,1])),
5h_MovingAvg_centered=series_fir(val, dynamic([1,1,1,1,1]), true, true)
| mv-expand val to typeof(long), t to typeof(datetime), 5h_MovingAvg to typeof(long), 5h_MovingAvg_centered to typeof(long)
| project t, 5h_MovingAvg, 5h_MovingAvg_centered, val
| render timechart

DynamoDB mapper conditional save failing for new row updates

Assume I have the following table in DDB. One hashkey (Lets call it 'Name'), one range key (lets call it 'Activity'), and one attribute (lets call it 'Date')
|---------------------|------------------|------------------|
| HashKey(S) | RangeKey(S) | Date(S) |
|---------------------|------------------|------------------|

|---------------------|------------------|------------------|
I want to do a conditional save on this such that I want to add a new "name + activity" and keep the most up to date date in the DB. So a breakdown of the 2 possibilities would be
1) If there is an existing hash+rangekey already based on what I have passed into the save, I want to check my condition expression and not update if it fails.
2) If it is a new hash+rangekey, I want a new row to be created, and not check my condition expression (since there are no values in the table to check on)
An example of what I tried
public void methodToDoSave() {
final Map<String, ExpectedAttributeValue> expectedAttributes =
getExpectedAttributes(date);
final DynamoDBSaveExpression saveExpression = new DynamoDBSaveExpression()
.withExpected(expectedAttributes);
mapper.save(dbItem, saveExpression);
}
private Map<String, ExpectedAttributeValue> getExpectedAttributes(
final Date date){
final Map expectedAttributeSetupForConditionalUpdate = new HashMap();
expectedAttributeSetupForConditionalUpdate
.put("Date",new ExpectedAttributeValue(new AttributeValue().withS(date))
.withComparisonOperator(ComparisonOperator.LE));
return expectedAttributeSetupForConditionalUpdate;
}
This works fine for doing the conditional checking and success/pass when the hash+range key is already in the table, however if I supply a new range key, the conditional check seems to always fail.
The stack trace for the conditional check is not that useful to explain to me the problem but my assumption is that the conditional check is being applied even for brand new row creations and so it is failing.
Is there a way to get this working in one save operation or will I need to read first, check if exists, if yes then save without the conditional checks, if no save with the conditional checks ?
I was able to leverage Tawan's hint above and do something like this.
final Map expectedAttributeSetupForConditionalUpdate = new HashMap();
expectedAttributeSetupForConditionalUpdate
.put("name", new ExpectedAttributeValue().withExists(false));
expectedAttributeSetupForConditionalUpdate
.put("activity", new ExpectedAttributeValue().withExists(false));
expectedAttributeSetupForConditionalUpdate
.put("Date", new ExpectedAttributeValue(new AttributeValue().withS(date))
.withComparisonOperator(ComparisonOperator.LE));
final DynamoDBSaveExpression saveExpression = new DynamoDBSaveExpression() .withExpected(expectedAttributeSetupForConditionalUpdate)
.withConditionalOperator(ConditionalOperator.OR);
I wasn't able to use the newer Condition expressions since DynamoDB mapper doesn't support them yet in the version I'm using. Essentially this "passes" the conditional check when the row doesn't exist, but uses the date when it does exist.

Application Insights Extract Nested CustomDimensions

I have some data in Application Insights Analytics that has a dynamic object as a property of custom dimensions. For example:
| timestamp | name | customDimensions | etc |
|-------------------------|---------|----------------------------------|-----|
| 2017-09-11T19:56:20.000 | Spinner | { | ... |
MyCustomDimension: "hi"
Properties:
context: "ABC"
userMessage: "Some other"
}
Does that make sense? So a key/value pair inside of customDimensions.
I'm trying to bring up the context property to be a proper column in the results. So expected would be :
| timestamp | name | customDimensions | context| etc |
|-------------------------|---------|----------------------------------|--------|-----|
| 2017-09-11T19:56:20.000 | Spinner | { | ABC | ...
MyCustomDimension: "hi"
Properties:
context: "ABC"
userMessage: "Some other"
}
I've tried this:
customEvents | where name == "Spinner" | extend Context = customDimensions.Properties["context"]
and this:
customEvents | where name == "Spinner" | extend Context = customDimensions.Properties.context
but neither seem to work. They give me a column at the end named "Context" but the column is empty - no values.
Any ideas?
EDIT:
Added a picture for clarifying the format of the data:
edited to working answer:
customEvents
| where name == "Spinner"
| extend Properties = todynamic(tostring(customDimensions.Properties))
| extend Context = Properties.context
you need an extra tostring and todynamic in here to get what you expect (and what i expected!)
the explanation i was given:
Dynamic field "promises" you the upper/outer level of key / value access (this is how you access customDimensions.Properties).
Accessing internal structure of that json depends on the exact format of customDimensions.Properties content. It doesn’t have to be json by itself. Even if it looks like a well structured json, it still may be just a string that is not exactly well formatted json.
So basically, it by default won't attempt to parse strings inside of a dynamic/json block because they don't want to spend a lot of time possibly trying and failing to convert nested content to json infinitely.
I still think that extra tostring shouldn't be required inside there, since todynamic should already be allowing both string and dynamic in validly, so i'm checking to see if the team that owns the query stuff can make that step better.
Thanks sooo much.. just to expand on the answer from John. We needed to graph duration of end-points using custom events. This query made it so we could specify the duration as our Y-axis in the chart:
customEvents
| extend Properties = todynamic(tostring(customDimensions.Properties))
| extend duration = todouble(todecimal(Properties.duration))
| project timestamp, name, duration

Legacy report application problems with autogenerate fields in runtime

I don't know if the follow code snippet intend to work in this way, because sometimes we "as developers" try automate creation of data display control where number of fields are uncontrolled and with similar data-binding, so before I review the application some guys left this :
Under ActiveReport_ReportStart() event :
for (Ind = 1; Ind <=CM.Length; Ind++) {
if (Ind == 1) {
Left = ((Line)rpt.Sections["PageHeader"].Controls["lnH8"]).Left + 0.05f;
} else if (Ind == 2) {
Left = ((Line)rpt.Sections["PageHeader"].Controls["lnH9"]).Left + 0.05f;
} else if (Ind == 3) {
Left = ((Line)rpt.Sections["PageHeader"].Controls["lnH10"]).Left + 0.05f;
}
TextBox TB = new TextBox();
TB.Size = ((Label)rpt.Sections["PageHeader"].Controls["tbColorway1"]).Size;
TB.Font = ((Label)rpt.Sections["PageHeader"].Controls["tbColorway1"]).Font;
TB.Width = ((Label)rpt.Sections["PageHeader"].Controls["tbColorway1"]).Width;
TB.Height = ((Label)rpt.Sections["PageHeader"].Controls["tbColorway1"]).Height;
TB.VerticalAlignment = VerticalTextAlignment.Top;
TB.Location = new System.Drawing.PointF(Left, ((Label)rpt.Sections["PageHeader"].Controls["tbColorway1"]).Top);
TB.DataField = "ColorText" + Ind + ColorwayNumber;
rpt.Sections["Detail"].Controls.Add(TB);
It doesn't have compilation error when is previewed, also others fields that are not auto-generated are displayed correctly (ReporHeader, ReportFooter), but IMHO I think is better to replace this mechanism by a subreport inside the detail section, of course these fields have to be displayed in Detail section of the report. Anyways I would like to see some recommendations because if is possible to auto-generated textbox or labels in runtime I will have to explain to boss why this code was not working, and if I have to use subreports instead, I need to know how to pass parameter (at least I need to work with two parameters for generate another sql query for it) and what "event" is proper to put script into it..
After I discovered that most important problem is to get report format changes by how many field/textbox were added to report detail in runtime restricted by a sqlquery return value, for example :
Returned SQLQuery value = 4
10 fields generated for detailed row 1
6 fields for row 2
4 fields for row 3
Detail fields are bound to a SQL Store Procedure*
Report will supossed to be printed/showed in this way :
//Report Init
Page 1 :
|field 1|field 2|field 3|field 4|
------------------------------------------------------
row1 | valA1 | valA2 | valA3 | valA4 |
------------------------------------------------------
row2 | valB1 | valB2 | valB3 | valB4 |
------------------------------------------------------
row3 | valC1 | valC2 | valC3 | valC4 |
------------------------------------------------------
Page 2 :
|field 1|field 2|field 3|field 4|
------------------------------------------------------
row1 | valA5 | valA6 | valA7 | valA8 |
------------------------------------------------------
row2 | valB5 | valB6 |
------------------------------------------------------
row3
------------------------------------------------------
Page 3 :
|field 1|field 2|field 3|field 4|
------------------------------------------------------
row1 | valA9 | valA10|
------------------------------------------------------
row2
------------------------------------------------------
row3
------------------------------------------------------
//End of Report
Any help will be appreciated
Thank you so much
It is perfectly fine to dynamically create fields on a report at runtime. The creation of those fields do indeed need to be done in the reportstart event or earlier (i.e. before calling ActiveReport.Run).
However, you could place the same logic to dynamically create those fields in a subreport and pass a parameter too, but in general subreports do impose additional overhead (and an additional query in most cases) so I wouldn't use a subreport unless there is a compelling benefit. However, there is a walkthrough on passing parameters to a subreport here.
The only thing that looks suspect in your code is the following line:
TB.Location = new System.Drawing.PointF(Left, ((Label)rpt.Sections["PageHeader"].Controls["tbColorway1"]).Top);
You are using the Top value from a control in the PageHeader, but TB is in the Detail section. I can understand reusing the Left value, but reusing the Top value wouldn't be consistent across different sections (Top is it's vertical position from the top of the section containing the control)
Now, it sounds like sometimes these fields do not appear on the report. Some things you can verify to troubleshoot the problem:
Determine if there is a binding problem or a visual/location problem. TO do this, just give the textbox a border or a background color or something so you can see it even if there is no text (due to failed data binding).
Start logging out the position of each textbox and the datafield value to a log file. When you notice the problem, go back to the log and see if you can identify what triggers the problem (maybe a specific index, location or datafield value?).
Finally, make sure that the page size (determined by the system's default printer) is not changing and maybe cutting off one of your dynamically added textboxes.
