I need to send get request like this to my api:
http://test.example.com/api/activity/search?word={word}&age={age}&free={free}
and then show this activities in my page with *ngFor, but when user fill inputs, i need to dynamically insert values in unnecessary arguments of this.
What i already done:
//activity.service.ts :
searchActivities(word?: any, age?: any, free?: any) {
let w, a, f;
//contat values from forms here
w = word ? `word=${word}` : '';
a = age ? `age=${age}` : '';
f = free ? `free=${free}` : '';
return this.http.get(`http://test.example.com/api/activity/search?${w}${a}${f}`);
}
as you noticed, i miss ampersands here, and it works only with one input, for example when user wants to see all free football activities, he can't.
In my component i have this:
activities = [];
args: any[] = [null, null, null]; //array for values
//funtction attached to input's events
setArgument(index, value) {
this.args[index] = value; //fills array with values from inputs
this.activityService
// spread operator gives error in typescript for some reason, so i decided to put arguments this way
.searchActivities(this.args[0], this.args[1], this.args[2])
.subscribe((data: Response) => this.activities = data.json());
}
example of inputs:
<md-checkbox (click)="setArgument(5, !IsFree)" [(ngModel)]="IsFree" name="free">Free</md-checkbox>
<md-input-container>
<input (focusout)="setArgument(0, word)" [(ngModel)]="word" name="word" mdInput placeholder="Search word">
</md-input-container>
I hope you understood what i'm trying to do, i'm novice at programming and maybe i do it completely bad way. Please advice how can i deal with ampersands, and maybe simplify or rewrite this code somehow
A good solution to your ampersand problem would be Array.prototype.join
So you might add code similar to the following:
w = word ? `word=${word}` : '';
a = age ? `age=${age}` : '';
f = free ? `free=${free}` : '';
q = [w, a, f].filter(function(x) { return x !== '' }).join('&');
return this.http.get(`http://test.example.com/api/activity/search?${q}`);
So you create an array containing all of your query strings, filter out the ones that are empty, and the join together into a string separated with ampersand characters.

Below is the code written by my collegue who doesnt work in the firm anymore. I am inserting records in object with data loader and I can see success message but I do not see any records in my object. I am not able to understand what below trigger is doing.Please someone help me understand as I am new to salesforce.

You might be looking in the wrong place. Check if there's an unit test written for this thing (there should be one, especially if it's deployed to production), it should help you understand how it's supposed to be used.
You're inserting records of QMBDataLogging__c but then it seems they're immediately deleted in DeleteDoAsLoggingRecords.deleteTheProcessRecords(processdIds). Whether whatever this thing was supposed to do succeeds or not.
This seems to be some poor man's CSV parser or generic "upload anything"... that takes data stored in QMBDataLogging__c and creates QMB_Initial_Letter__c out of it.
QMBLetteTypeToVfPage__c.getAll() suggests you could go to Setup -> Custom Settings, try to find this thing and examine. Maybe it has some values in production but in your sandbox it's empty and that's why essentially nothing works? Or maybe some values that are there are outdated?
There's some comparison if what you upload into Field1__c can be matched to what's in that custom setting. I guess you load some kind of subtype of your QMB_Initial_Letter__c in there. Record Type name and list of fields to read from your log record is also fetched from custom setting based on that match.
Then this thing takes what you pasted, looks at the list of fields in from the custom setting and parses it.
Let's say the custom setting contains something like
Name = XYZ, FieldAPINames__c = 'Name,SomePicklist__c,SomeDate__c,IsActive__c'
This thing will look at first record you inserted, let's say you have the CSV like that
Field1__c,Field2__c,Field3__c,Field4__c
XYZ,Closed,2022-09-15,true
This thing will try to parse and map it so eventually you create record that a "normal" apex code would express as
new QMB_Initial_Letter__c(
Name = 'XYZ',
SomePicklist__c = 'Closed',
SomeDate__c = Date.parse('2022-09-15'),
IsActive__c = true
);
It's pretty fragile, as you probably already know. And because parsing CSV is an art - I expect it to absolutely crash and burn when text with commas in it shows up (some text,"text, with commas in it, should be quoted",more text).
In theory admin can change mapping in setup - but then they'd need to add new field anyway to the loaded file. Overcomplicated. I guess somebody did it to solve issue with Record Type Ids - but there are better ways to achieve that and still have normal CSV file with normal columns and strong type matching, not just chucking everything in as strings.
In theory this lets you have "jagged" csv files (row 1 having 5 fields, row 2 having different record type and 17 fields? no problem)
Your call whether it's salvageable or you'd rather ditch it and try normal loading of QMB_Initial_Letter__c records. (get back to your business people and ask for requirements?) If you do have variable number of columns at source - you'd need to standardise it or group the data so only 1 "type" of records (well, whatever's in that "Field1__c") goes into each file.
For interaction with an API, I need to pass the course code in <string><space><number> format. For example, MCTE 2333, CCUB 3621, BTE 1021.
Yes, the text part can be 3 or 4 letters.
Most users enter the code without the space, eg: MCTE2333. But that causes error to the API. So how can I add a space between string and numbers so that it follows the correct format.
You can achieve the desired behaviour by using regular expressions:
void main() {
String a = "MCTE2333";
String aStr = a.replaceAll(RegExp(r'[^0-9]'), ''); //extract the number
String bStr = a.replaceAll(RegExp(r'[^A-Za-z]'), ''); //extract the character
print("$bStr $aStr"); //MCTE 2333
}
Note: This will produce the same result, regardless of how many whitespaces your user enters between the characters and numbers.
Try this.You have to give two texfields. One is for name i.e; MCTE and one is for numbers i.e; 1021. (for this textfield you have to change keyboard type only number).
After that you can join those string with space between them and send to your DB.
It's just like hack but it will work.
Scrolling down the course codes list, I noticed some unusual formatting.
Example: TQB 1001E, TQB 1001E etc. (With extra letter at the end)
So, this special format doesn't work with #Jahidul Islam's answer. However, inspired by his answer, I manage to come up with this logic:
var code = "TQB2001M";
var i = course.indexOf(RegExp(r'[^A-Za-z]')); // get the index
var j = course.substring(0, i); // extract the first half
var k = course.substring(i).trim(); // extract the others
var formatted = '$j $k'.toUpperCase(); // combine & capitalize
print(formatted); // TQB 1011M
Works with other formats too. Check out the DartPad here.
Here is the entire logic you need (also works for multiple whitespaces!):
void main() {
String courseCode= "MMM 111";
String parsedCourseCode = "";
if (courseCode.contains(" ")) {
final ensureSingleWhitespace = RegExp(r"(?! )\s+| \s+");
parsedCourseCode = courseCode.split(ensureSingleWhitespace).join(" ");
} else {
final r1 = RegExp(r'[0-9]', caseSensitive: false);
final r2 = RegExp(r'[a-z]', caseSensitive: false);
final letters = courseCode.split(r1);
final numbers = courseCode.split(r2);
parsedCourseCode = "${letters[0].trim()} ${numbers.last}";
}
print(parsedCourseCode);
}
Play around with the input value (courseCode) to test it - also use dart pad if you want. You just have to add this logic to your input value, before submitting / handling the input form of your user :)
I'm creating a query to search the db using EF. TdsDb being the EF context.
string searchValue = "Widget";
TdsDb tdsDb = new TdsDb();
IQueryable<Counterparty> counterparties;
I can do exact match:
counterparties = tdsDb.Counterparties.Where(x => x.CounterpartyName == searchValue);
or wildcard match:
counterparties = tdsDb.Counterparties.Where(x => x.CounterpartyName.Contains(searchValue));
But I want to be able to do both i.e. (psudo code)
counterparties = tdsDb.Counterparties.Where(x =>
if (searchValue.EndsWith("%"))
{
if (searchValue.StartsWith("%"))
{x.CounterpartyName.Contains(searchValue)}
else
{x.CounterpartyName.StartsWith(searchValue)}
}
else
{x => x.CounterpartyName == searchValue}
);
Now clearly I can't put an if statement in the where clause like that. But I also can't duplicate the queries: shown here they are hugely dumbed down. The production query is far longer, so having multiple versions of the same long query that vary on only one clause seems very unhealthy and unmaintainable.
Any ideas?
You should be able to use the ternary operator:
bool startsWithWildCard = searchValue.StartsWith("%");
bool endsWithWildCard = searchValue.EndsWith("%");
counterparties = tdsDb.Counterparties.Where(x =>
endsWithWildCard
? (startsWithWildCard
? x.CounterpartyName.Contains(searchValue)
: (x.CounterpartyName.StartsWith(searchValue)))
: (x.CounterpartyName == searchValue));
Did you test btw if querying by a searchValue that has an % at the beginning or end works as you expect? It might be possible that % will be escaped as a character to query for because StartsWith and Contains will prepend/append % wildcards to the generated SQL search term anyway. In that case you need to cut off the % from the searchValue before you pass it into StartsWith or Contains.
Zend_valdiate_alpha combined with special characters
Need to combine An alphanumeric character or underscore with string .
for example : need to add control for City name with
not necessary with zend_alpha it can be another way
any suggestions ??
I have exactly the same problem. I need to allow commas, alphas, and whitespaces. The most simple solution, I can think of, is to define callback validation function like this:
$myValidator = new Zend_Validate_Callback(function($value) {
$value = preg_replace('/,/', '', $value);
$alphaValidator = new Zend_Validate_Alpha(array('allowWhiteSpace' => true));
if ($alphaValidator->isValid($value)) return true;
return false;
});
And using it like this:
if ($myValidator->isValid($input)) {
// input valid
} else {
// input invalid
}
I know this is old but perhaps it can help somebody and I would be interested if there is a simpler solution.
I am using jqgrid in my new project.
In a specific case I need to use a select element in the grid. No problem.
I define the colModel and the column for example like (from wiki)
colModel : [
...
{name:'myname', edittype:'select', editoptions:{value:{1:'One',2:'Two'}} },
...
]
But now when I load my data I would prefer the column "myname" to contain the value 1.
This won't work for me instead it has to contain the value "One".
The problem with this is that the text-part of the select element is in my case localized in the business layer where the colModel is dynamically generated. Also the datatype for the entity which generates the data via EF 4 may not be a string. Then I have to find the correct localized text and manipulate the data result so that the column "myname" does not containt an integer which is typically the case but a string instead with the localized text.
There is no option you can use so that when the data contains the value which match an option in the select list then the grid finds that option and presents the text.
Now the grid presents the value as a text and first when I click edit it finds the matching option and presents the text. When I undo the edit it returns to present the value again.
I started to think of a solution and this is what I came up with. Please if you know a better solution or if you know there is a built in option don't hesitate to answer.
Otherwise here is what I did:
loadComplete: function (data) {
var colModel = grid.getGridParam('colModel');
$.each(colModel, function (index, col) {
if (col.edittype === 'select') {
$.each(grid.getDataIDs(), function (index, id) {
var row = grid.getRowData(id);
var value = row[col.name];
var editoptions = col.editoptions.value;
var startText = editoptions.indexOf(value + ':') + (value + ':').length;
var endText = editoptions.indexOf(';', startText);
if (endText === -1) { endText = editoptions.length; }
var text = editoptions.substring(startText, endText);
row[col.name] = text;
grid.setRowData(id, row);
});
}
});
}
It works and I will leave it like this if nobody comes up with a better way.
You should just include additional formatter:'select' option in the definition of the column. See the documentation for more details.
