I'm performing a logical replication from our PostgreSQL server to AWS RDS, using the database migration tool (DMS). Most tables were migrated successfully, but I'm having troubles with a couple of the tables.
When I run the task to load the table, I get this error on the logs of RDS:
ERROR: invalid input value for enum property_type: ""

The type of column property_type is a nullable enum that takes as values Condominium, Cooperative, ManufacturedHome, SingleFamily, Townhouse and TwoToFourFamily.
I'm experiencing a similar issue with another table from the same database, where I get:
ERROR: malformed range literal: ""
DETAIL: Missing left parenthesis or bracket.
CONTEXT: unnamed portal parameter $3 = ''
STATEMENT: INSERT INTO "public"."selections_sampling_data"("id","sow_id","period","loan_number","field_data","selected_on","substituted_on","substitution_for_id","received_for_review_on","created_at","updated_at","selected_for","selection_reason","selections_sampling_strategy_id") values ($1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$11,$12,$13,$14)
This one doesn't explicitly tell me which column generated the error, but parameter $3 should correspond with the period column, which is a daterange type.
In both cases, the DMS task seems to be querying for an empty string as value, which is not allowed by those data types.
I don't know if this is an error with my schema, or how I configured the DMS task.

So, after digging through AWS documentation and contacting support, I learned that enum data types don't migrate using DMS. The task will fail no matter what.
If your database has enum columns, you need to find another solution, i.e. barman and run it on an EC2 instance.
I have a list of statefull widget which I use to navigate from pages. but when I was trying to push these List element in Navigator.push(), it says "Reading static variable during its initialization".
here's the list:
List<ActionScreen> fullBodyNavigation = [
ActionScreen(title: 'demo data', number: 20, gifDirectory: "assets/gifs/demodata.gif", currentList: fullBodyNavigation,
frameMin: 0, frameMax: 17, milisecondAnimation: 800, milisecondTimer: 800, sessionNumber: 1,),
ActionScreen(title: 'demodata', number: 15, gifDirectory: "assets/gifs/demodata.gif", currentList: fullBodyNavigation,
frameMin: 0, frameMax: 30, milisecondAnimation: 1200, milisecondTimer: 1200, sessionNumber: 2,),
ActionScreen(title: 'demodata', number: 15, gifDirectory: "assets/gifs/demodata.gif", currentList: fullBodyNavigation,
frameMin: 0, frameMax: 2, milisecondAnimation: 2000, milisecondTimer: 2000, sessionNumber: 3,),
.............
]
here's the push method:
onPress: () {
Navigator.push(context, MaterialPageRoute(builder: (context) => fullBodyNavigation[0],),);
},
I foud a solution in stackoverflow which said I have to use 'data' such as "fullBodyNavigation.data[0]". but ide said "getter data is not defined". can anyone pls help?
here's that solution's link: Reading static variable during its initialization | Flutter
The problem is in the way you have created the navigation pages list:
List<ActionScreen> fullBodyNavigation = [
ActionScreen(title: 'demo data',
number: 20,
gifDirectory: "assets/gifs/demodata.gif",
currentList: fullBodyNavigation,
frameMin: 0,
frameMax: 17,
milisecondAnimation: 800,
milisecondTimer: 800,
sessionNumber: 1,
),
.............
]
Why do you want to pass currentList: fullBodyNavigation to ActionScreen. So basically, you are trying to access the list inside the list itself. The chicken and egg problem. THat's what compiler is warning you with the error.
To fix this, dont pass currentList: fullBodyNavigation to ActionScreen. Instead make fullBodyNavigation a static field and in ActionScreen just access it with the class name. That should do your thing and also make the compiler happy
I have a layer that renders point features in a geojson source as circles. Here's an example of one of the features:
{
type: 'Feature',
properties: {
color: 'red',
red: true,
green: false
},
geometry: {
type: 'Point',
coordinates: [-77.038659, 38.931567]
}
};
I want circle-opacity to be a product of 3 factors (some properties on the features, map zoom, and a boolean in feature-state for whether that feature should be hidden). I can't figure out a way to write an expression that accounts for all three. Restrictions around zoom rules seem to be the issue.
Here's the logic I am trying to write:
if (feature-state.hidden) {
opacity = 0;
} else if (properties.red) {
opacity = 1;
} else if (properties.green and zoom >= 10) {
opacity = 1;
} else if (zoom >= 15) {
opacity = 1;
} else {
opacity = 0;
}
I tried writing an opacity expression like this:
'circle-opacity': [
'case',
['to-boolean', ['feature-state', 'hidden']], 0,
['to-boolean', ['get', 'red']], 1,
['to-boolean', ['get', 'green']], ['case', ['>=', ['zoom'], 10], 1, 0], // I could also write a permutation of this using an ['all'] rule
['>=', ['zoom'], 15], 1,
0,
],
That gets rejected with this message: "Error: layers.places.paint.circle-opacity: "zoom" expression may only be used as input to a top-level "step" or "interpolate" expression."
So then I tried something like this:
'circle-opacity': [
'step',
['zoom'],
0,
[
'case',
['to-boolean', ['get', 'red'], false], 1,
['to-boolean', ['get', 'green'], false], 10,
15
],
1
]
That gets rejected with this message: "Error: layers.places.paint.circle-opacity[3]: Input/output pairs for "step" expressions must be defined using literal numeric values (not computed expressions) for the input values."
As you can see, I hadn't even gotten around to adding the feature-state checks yet.
Here's a JSFiddle to play with: https://jsfiddle.net/rognstad/px4c8tbe/17/
I think I can make it work by breaking each color out into its own layer with a minZoom property and then only using an opacity expression for feature-state, but that feels really clunky and will result in worse performance.
It seems like there has to be a better way. Do you have any better suggestions for how to achieve this? Thanks!
You're really close. You're getting this error:
Error: layers.places.paint.circle-opacity[3]: Input/output pairs for "step" expressions must be defined using literal numeric values (not computed expressions) for the input values.
Because you've got the order of arguments in your ['step'] expression slightly wrong. It needs to go:
['step', ['zoom'], <value at zoom 0>, <X>, <value at zoom X>, <Y>, <value at zoom Y>
So you don't want that first 0 there.
If we refactor your pseudo code a bit you should be able to get there:
step
zoom
// zoom 0 to 10
if (!feature-state.hidden && properties.red) {
1
} else {
0
}
10 // zoom level 10+
if (!feature-state.hidden && (properties.red || properties.green) {
1
} else {
0
}
15 // zoom level 15+
if (!feature-state.hidden) {
1
} else {
0
}
The expression code will look something like this. You'll have to add appropriate type conversions probably. (I haven't tested it).
['step', ['zoom'],
['case', ['all', ['!', ['feature-state', 'hidden']], ['get', 'red'], 1, 0],
10,
['case', ['all', ['!', ['feature-state', 'hidden']], ['any', ['get', 'red'], ['get', 'green']], 1, 0],
15,
['case', [['!', ['feature-state', 'hidden']], 1, 0]],
I am playing around with Google Chart to look a certain way. In this situation I have a combo chart a line and column chart.
I have stumble upon a view "layout" problems
How do replace the show2r legend with just some custom text? At
the moment says: y = 2.032E-4 * x - 8.203 r^2 = 7.005E-3 and I want
to replace it with "Trendline (Lineair)
2/ Also the legend gets a
1/2 and Arrows left and right. I like the legend to always be
visible?
3/ The x axis doesn't display all dates, how can I set that
as a default?
4/ How do I add vertical line in say month June??
Regards
to change the trendline label in the legend, use option --> labelInLegend
there are no standard options to change the value in the tooltip,
but it can be changed manually using event --> onmouseover
when the legend's position is top,
you can use option --> legend.maxLines
to increase the number of lines available and prevent the arrows...
to ensure all dates are shown on the x-axis,
allow enough room by using option --> chartArea.bottom
see following working snippet for examples of each...
google.charts.load('current', {
packages: ['corechart']
}).then(function () {
var data = google.visualization.arrayToDataTable([
['x', 'y0', 'y1'],

Am new to PHP coding & have a few google charts working. All of these charts I've generated so far are based on (date,number of event occurrences) type of chart. I'm trying to plot a google chart whose data is the output of SQL query.
The output of SQL query looks as below
|SERIES|DATE_1|DATE_2|DATE_3|
|a|2|3|
|b|4|6|
|c|7|8|
Both SERIES & DATE_1 can vary. That is to say, based on various conditions in the SQL query, the number of DATE_ can be vary & so can the SERIES.
I would then have to pass this output to the google chart plot code.
Here is what i've tried coding so far
$link = mysql_connect("localhost", "user", "pass");
$dbcheck = mysql_select_db("database");
if ($dbcheck) {
$chart_array_1[] = "['MY_DATE','MY_NAME','#NUM_OCCURENCES']";
$result = mysql_query($sql);
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$my_date=$row["MY_DATE"];
$my_ins=$row["MY_NAME"];
$my_count=$row["MY_COUNT"];
$chart_array_1[]="['".$my_date."','".$my_ins."',".$my_count."]";
}
}
}
mysqli_close($link);

I'm unable to plot the graph. I get the error "Data column(s) for axis #0 cannot be of type stringĂ—". Could someone please help me here.
I'd like to see a,b,c etc as separate series each while the date goes on to the X-Axis. Please note am after generating data dynamically using SQL query & not a static array which most examples demonstrate. Could someone please help?
Managed to implement thing a different way. Hence this question can be ignored.
