React native require images breaks with variables - react-native

How come this line works with no errors
var gicon = species[ii].color[0] ? require('../assets/gLight.jpg') : require('../assets/nLight.png');
while this line throws an error?
which_light = "gLight";
var gicon = species[ii].color[0] ? require('../assets/' + which_light + '.jpg') : require('../assets/nLight.png');

Image names are resolved during packaging. There is a section about it in the docs. You can solve your problem by defining constants for the images:
const LIGHT_G = require('../assets/gLight.jpg');
const LIGHT_N = require('../assets/nLight.png');
which_light = LIGHT_G;
var gicon = species[ii].color[0] ? which_light : LIGHT_N;
You have to reference all possible images like this.

Questions regarding update of table on Prestashop

I'm trying to update ps_stock_available when I modify the product on Prestashop. But it's unsuccessfull. Could you help me please ?
public function hookActionUpdateQuantity(array $params)
{
$id_product = $params['id_product'];
$product = new Product((int)$id_product);
$id_category = $product->id_category_default;
$db = \Db::getInstance();
$request_loc='SELECT location FROM `'._DB_PREFIX_.'category_location` WHERE `id_category` = '.(int)$id_category;
$location = $db->getValue($request_loc);
$request_id_stock='SELECT id_stock_available FROM `'._DB_PREFIX_.'stock_available` WHERE `id_product` = '.(int)$id_product;
$id_stock_available = $db->getValue($request_id_stock);
$result = $db->update('stock_available', array('location' => $location), '`id_stock_available` = '.(int)$id_stock_available);
}
I have written this code but it doesn't seem to work.
in order to accomplish this task I would rely to the native StockAvailable class metehods getStockAvailableIdByProductId() and setLocation() (check the classes/stock/StockAvailable.php file).
Anyway your code seems to be correct, so I would definitely check for undefined variables and/or something not working in the $db->update statement.
In case, you can change it to :
$db->execute('UPDATE '._DB_PREFIX_.'stock_available SET `location` = "'.pSQL($location).'" WHERE id_stock_available = '.(int)$id_stock_available;

AmCharts 4 : Can't customize (color, strokeWidth) my series

EDIT : OK, It was my css page which had a rule on path, 'cause I use svg a lot. Removed that rule and the problem was gone !
I'm facing something pretty annoying and which I do not understand.
I'm using amChart to make a XY chart with multiple series. Not that hard.
The thing is, I can't customize my series ! Bullets and legend are ok, but not series.
Here's a screenshot for better understanding :
MyWeirdChart (new OP can't embed images, sorry)
As you can see I have my custom bullet pushed on my series and my legend is exactly what I want for my chart BUT series are staying unchanged.
Here is my JS draw function :
function drawChart(dateArray, casesArray, deathsArray, healedArray, hospitalizationsArray, reanimationsArray) {
am4core.useTheme(am4themes_animated);
var chart = am4core.create("chartdiv", am4charts.XYChart);
chart.data = generateChartData(dateArray, casesArray, deathsArray, healedArray, hospitalizationsArray, reanimationsArray);
var dateAxis = chart.xAxes.push(new am4charts.DateAxis());
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
function pushSeries(field, name, color) {
let series = chart.series.push(new am4charts.LineSeries());
series.dataFields.valueY = field;
series.dataFields.dateX = "date";
series.name = name;
series.tooltipText = name + ": [b]{valueY}[/]";
series.stroke = am4core.color(color);
series.strokeWidth = 3;
series.fill = am4core.color(color);
series.fillOpacity = 0.5;
let bullet = series.bullets.push(new am4charts.CircleBullet());
bullet.circle.stroke = am4core.color(color);
bullet.circle.strokeWidth = 2;
bullet.circle.fill = am4core.color(color);
bullet.circle.fillOpacity = 0.5;
bullet.circle.radius = 3;
}
pushSeries("cases", "Cas confirmés", "#32B3E3");
pushSeries("healed", "Guéris", "#00C750");
pushSeries("hospitalizations", "Hospitalisations", "#FFBB33");
pushSeries("reanimations", "Réanimations", "#FE3446");
pushSeries("deaths", "Morts", "black");
chart.cursor = new am4charts.XYCursor();
chart.scrollbarX = new am4core.Scrollbar();
chart.legend = new am4charts.Legend();
chart.cursor.maxTooltipDistance = 0;
}
Did I miss something ? I crawled forums and documentations and I'm now helpless.
My code is in my webpack app.js file. But I include amCharts with HTML scripts,
<script src="https://www.amcharts.com/lib/4/core.js"></script>
<script src="https://www.amcharts.com/lib/4/charts.js"></script>
<script src="https://www.amcharts.com/lib/4/themes/animated.js"></script>
not with webpack import. But I guess that if this was the problem, I would not be able to draw a chart at all.
OK, It was my css page which had a rule on path, 'cause I use svg a lot. Removed that rule and the problem was gone !

Getting error for variable does not exist in current context cshtml?

i have following code for getting error
$('#Template').click(function () {
var selectedTempleteType = $('#BulkLoadActionDropDownId option:selected').val();
var path = '#Url.Content("~/Upload/DownloadBulkLoadActionTemplate?templateType=" + selectedTempleteType)';
$(this).attr("href", path);
});
error showing for "selectedTempleteType".
selectedTempleteType is a client-side JS variable, you cannot use it inside #Url.Content() which runs server-side (and #Url.Content() is incorrect to map URL path with query string, use #Url.Action() instead). You should change from this:
var path = '#Url.Content("~/Upload/DownloadBulkLoadActionTemplate?templateType=" + selectedTempleteType)';
to this one:
var path = '#Url.Action("DownloadBulkLoadActionTemplate", "Upload")?templateType=' + selectedTempleteType;
Or using placeholder inside #Url.Action() with replace() in client-side:
var path = '#Url.Action("DownloadBulkLoadActionTemplate", "Upload", new { templateType = "xxxx" })';
path = path.replace("xxxx", selectedTempleteType);

How to pass variable from another lua file?

How to pass variable from another lua file? Im trying to pass the text variable title to another b.lua as a text.
a.lua
local options = {
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
b.lua
local score_label_2 = display.newText({parent=uiGroup, text=title, font=native.systemFontBold, fontSize=128, align="center"})
There are a couple ways to do this but the most straightforward is to treat 'a.lua' like a module and import it into 'b.lua' via require
For example in
-- a.lua
local options =
{
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
return options
and from
-- b.lua
local options = require 'a'
local score_label_2 = display.newText
{
parent = uiGroup,
text = options.title,
font = native.systemFontBold,
fontSize = 128,
align = "center"
}
You can import the file a.lua into a variable, then use it as an ordinary table.
in b.lua
local a = require("a.lua")
print(a.options.title)

Adobe AIR NativeProcess fails with spaces in arguments?

I have a problem running the NativeProcess if I put spaces in the arguments
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
fPath = "C:\\Windows\\System32\\cmd.exe";
args.push("/c");
args.push(scriptDir.resolvePath("helloworld.bat").nativePath);
}
file = new File(fPath);
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
args.push("blah");
nativeProcessStartupInfo.arguments = args;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
in the above code, if I use
args.push("blah") everything works fine
if I use
args.push("blah blah") the program breaks as if the file wasn't found.
Seems like I'm not the only one:
http://tech.groups.yahoo.com/group/flexcoders/message/159521
As one of the users their pointed out, it really seems like an awful limitation by a cutting edge SDK of 21st century. Even Alex Harui didn't have the answer there and he's known to workaround every Adobe bug:)
Any ideas?
I am using AIR 2.6 SDK in JavaScript like this, and it is working fine even for spaces.
please check your code with this one.
var file = air.File.applicationDirectory;
file = file.resolvePath("apps");
if (air.Capabilities.os.toLowerCase().indexOf("win") > -1)
{
file = file.resolvePath(appFile);
}
var nativeProcessStartupInfo = new air.NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
process = new air.NativeProcess();
process.addEventListener(air.ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(air.ProgressEvent.STANDARD_INPUT_PROGRESS, inputProgressListener);
process.start(nativeProcessStartupInfo);
To expand on this: The reason that this works (see post above):
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
is that air expects that the arguments being passed to the nativeProcess are delimited by spaces. It chokes if you pass "C:\folder with spaces\myfile.doc" (and BTW for AIR a file path for windows needs to be "C:\\folder with spaces\\myfile.doc") you would need to do this:
args.push("C:\\folder");
args.push("with");
args.push("spaces\\myfile.doc");
Hence, something like this works:
var processArgs = new air.Vector["<String>"]();
var path = "C:\\folder with spaces\\myfile.doc"
var args = path.split(" ")
for (var i=0; i<args.length; i++) {
processArgs.push(args[i]);
};
UPDATE - SOLUTION
The string generated by the File object by either nativePath or resolvePath uses "\" for the path. Replace "\" with "/" and it works.
I'm having the same problem trying to call 7za.exe using NativeProcess. If you try to access various windows directories the whole thing fails horribly. Even trying to run command.exe and calling a batch file fails because you still have to try to pass a path with spaces through "arguments" on the NativeProcessStartupInfo object.
I've spent the better part of a day trying to get this to work and it will not work. Whatever happens to spaces in "arguments" totally destroys the path.
Example 7za.exe from command line:
7za.exe a MyZip.7z "D:\docs\My Games\Some Game Title\Maps\The Map.map"
This works fine. Now try that with Native Process in AIR. The AIR arguments sanitizer is FUBAR.
I have tried countless ways to put in arguments and it just fails. Interesting I can get it to spit out a zip file but with no content in the zip. I figure this is due to the first argument set finally working but then failing for the path argument.
For example:
processArgs[0] = 'a';
processArgs[1] = 'D:\apps\flash builder 4.5\project1\bin-debug\MyZip.7z';
processArgs[2] = 'D:\docs\My Games\Some Game Title\Maps\The Map.map';
For some reason this spits out a zip file named: bin-debugMyZip.7z But the zip is empty.
Whatever AIR is doing it is fraking up path strings. I've tried adding quotes around those paths in various ways. Nothing works.
I thought I could fall back on calling a batch file from this example:
http://technodesk.wordpress.com/2010/04/15/air-2-0-native-process-batch-file/
But it fails as well because it still requires the path to be passed through arguments.
Anyone have any luck calling 7z or dealing with full paths in the NativeProcess? All these little happy tutorials don't deal with real windows folder structure.
Solution that works for me - set path_with_space as "nativeProcessStartupInfo.workingDirectory" property. See example below:
public function openPdf(pathToPdf:String):void
}
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
var file:File = File.applicationDirectory.resolvePath("C:\\Windows\\System32\\cmd.exe");
nativeProcessStartupInfo.executable = file;
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
nativeProcessStartupInfo.workingDirectory = File.applicationDirectory.resolvePath(pathToPdf).parent;
var processArgs:Vector.<String> = new Vector.<String>();
processArgs[0] = "/k";
processArgs[1] = "start";
processArgs[2] = "test.pdf";
nativeProcessStartupInfo.arguments = processArgs;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
}
args.push( '"blah blah"' );
Command line after all supports spaces if they are nested whithin "".
So if lets say you have a file argument :
'test/folder with space/blah'
Convert it to the following
'test/"folder with space"/blah'
Optionally use a filter:
I once had a problem like this in AIR, i just simply filter the text before i push it into the array. My refrence use CASA lib though
import org.casalib.util.ArrayUtil;
http://casalib.org/
/**
* Filters a string input for 'safe handling', and returns it
**/
public function stringFilter(inString:String, addPermitArr:Array = null, permitedArr:Array = null):String {
var sourceArr:Array = inString.split(''); //Splits the string input up
var outArr:Array = new Array();
if(permitedArr == null) {
permitedArr = ("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890" as String).split('');
}
if( addPermitArr != null ) {
permitedArr = permitedArr.concat( addPermitArr );
}
for(var i:int = 0; i < sourceArr.length; i++) {
if( ArrayUtil.contains( permitedArr, sourceArr[i] ) != 0 ) { //it is allowed
outArr.push( sourceArr[i] );
}
}
return (outArr.join('') as String);
}
And just filter it via
args.push( stringFilter( 'blah blah', new Array('.') ) );
Besides, it is really bad practice to use spaces in file names / arguments, use '_' instead. This seems to be originating from linux though. (The question of spaces in file names)
This works for me on Windws7:
var Xargs:Array = String("/C#echo#a trully hacky way to do this :)#>#C:\\Users\\Benjo\\AppData\\Roaming\\com.eblagajna.eBlagajna.POS\\Local Store\\a.a").split("#");
var args:Vector.<String> = new Vector.<String>();
for (var i:int=0; i<Xargs.length; i++) {
trace("Pushing: "+Xargs[i]);
args.push(Xargs[i]);
};
NPI.arguments = args;
If your application path or parameter contains spaces, make sure to wrap it in quotes. For example path of the application has spaces C:\Program Files (x86)\Camera\Camera.exe use quotes like:
"C:\Program Files (x86)\Camera\Camera.exe"
