I'm working on a Symfony2.3 project and I need an input number that lets me save the value with decimals and samples the arrows. With the following code I can show the decimals but then only the whole part is saved.
Entity
/**
*
* #ORM\Column(name="horas", type="decimal", scale=1)
* #Assert\NotBlank()
*/
private $hours;
FormType
->add('hours','integer', array('required' => true,'attr' => array('min' => 15,'max' => 40,'step' => 0.5)))
I appreciate your help.
To store a floating point value in a decimal field, you must first decide how many digits you need before the point, and how many after. For example, your field could look like this:
/**
* #ORM\Column(type="decimal", precision=3, scale=1)
* #Assert\Range(min=15, max=40)
*/
private $hours;
In a decimal field, the precision is always the total number of digits, while scale denotes the length of the fraction part. In the example above, the decimal field could store values between 0 and 99, while one digit after the point would be stored.
Note that Doctrine will represent the field as string, so if you retrieve the entity, the value of the field would be "20.5" (i.e. a string). You must manually convert the value to a float again. This can be done in the getter for the field:
public function getHours()
{
return (float) $this->hours;
}

I am using the following to get the transaction timestamp:
val outputStateRef = StateRef(ledgerTx.id, 0)
val queryCriteria = QueryCriteria.VaultQueryCriteria(stateRefs = listOf(outputStateRef))
val results = serviceHub.vaultService.queryBy<ContractState>(queryCriteria)
val recordedTime = results.statesMetadata.singleOrNull()?.recordedTime
The problem is the transaction time is not always returned, sometimes null is returned for the timestamp.
Why is this happening and how can I ensure the timestamp is always returned?
results is Vault.Page<ContractState> which contains the following variables:
/**
* Returned in queries [VaultService.queryBy] and [VaultService.trackBy].
* A Page contains:
* 1) a [List] of actual [StateAndRef] requested by the specified [QueryCriteria] to a maximum of [MAX_PAGE_SIZE].
* 2) a [List] of associated [Vault.StateMetadata], one per [StateAndRef] result.
* 3) a total number of states that met the given [QueryCriteria] if a [PageSpecification] was provided,
* otherwise it defaults to -1.
* 4) Status types used in this query: [StateStatus.UNCONSUMED], [StateStatus.CONSUMED], [StateStatus.ALL].
* 5) Other results as a [List] of any type (eg. aggregate function results with/without group by).
*
* Note: currently otherResults are used only for Aggregate Functions (in which case, the states and statesMetadata
* results will be empty).
*/
As it looks from your code, if result page contains multiple StateAndRef, the method code singleOrNull()? will actually return null.
This is my guess based on available codes, please share more information if this wasnt the cause of the issue.
I would add your own timestamp to the state and record it in the flow.
Or, you can add a Time-Window to the transaction (https://docs.corda.net/api-transactions.html#time-windows). I believe this also ensures that the statesMetadata.recordedTime will not be null.
I am currently stuck on a probably very simple question.
How do I validate my DateIntervalType to be != 0 - meaning atleast something has been selected.
And how do I set a minimum/maximum: for example minimum interval of 1 day.
Background: I want to send an email every X years/months/days depending on the user select - an interval of 0 would mean permanent email sending, which I do not want.
Sadly I did not find anything helpful yet. Also tried integer assertations like #Assert\GratherThan etc. but that does not work.
Thanks in advance
Solution: Thanks to #Arleigh Hix for putting me on the right direction.
I solved my problem with following solution:
/**
* #Assert\Expression("this.checkInterval()")
*/
private $interval;
public function checkInterval() {
return $this->getTimestamp()->add($this->getInterval()) > $this->getTimestamp(); //getTimestamp() returns a DateTime
}
So basically just add the interval to any date and compare the new date to the initial date. With this way you can also get the difference in seconds and compare for min max values.
Better practise is probably to create a custom validator which will be my next step.
It looks you should be able to use an Expression constraint Maybe like this (I'm not sure about syntax for constructing the \DateInterval in the annotation)
/**
* #Assert\Expression(
* "value >= minimum",
* values = { "minimum": new \DateInterval('P1D') }
* )
*/
$dateIntervalField;
Alternatively, you should be able to set your minimum interval to an entity property and then compare value to that.
public function __construct()
{
$this->minInterval = new \DateInterval('P1D');
}
/**
* #Assert\GreaterThanOrEqual(
* value = this.minInterval
* )
*/
$dateIntervalField;
I want to use alnum type but without spaces, can i do something with that or i have to make my own type? I want to make username without spaces.
Like this here:
private $username;
/**
* #Assert\NotBlank()
* #Assert\Length(max=4096)
* #Assert\Type(type="alnum")
The most powerful validation to solve this kind of trouble is the Regex Constraint.
For your case (a very simple case) is enough to use (see Length)
/**
* #Assert\Length(max=4096, minMessage="...", maxMessage="...")
* #Assert\Regex(
* pattern = "/^[a-z0-9]+$/i",
* htmlPattern = "^[a-zA-Z0-9]+$",
* message="Your name must contain only letter or numbers"
* )
*/
It is possible to unify both validator here in only one validator constraint but keep in mind that you lose the ability to show the exact error message if you have multiple conditions (like length and forbidden chars)
/**
* #Assert\Regex(
* pattern = "/^[a-z0-9]{1,4096}$/i",
* htmlPattern = "^[a-zA-Z0-9]{1,4096}$",
* message="Your name must contain only letter or numbers and must have length between 1 and 4096"
* )
*/
Where {1,4096} is the min and max values for limits of length string.
The htmlPattern and message are optional.
I am getting comments from wp_comments table but when display it on browser it does not show emoticons instead showing :) and :D though comment have some emoticons. I read Using Smilies and now I want to create custom function which replace :) with appropriate icon and so on.
But I have no idea how?
This page describes the use of Emoticons/Smileys as graphics:
http://codex.wordpress.org/Using_Smilies
Go to your Admin Panel
Select Settings -> Writing
Check the box for "Convert emoticons like :-) and :-P to graphics on display"
If you're looking for the wp-script that converts the emoticons look here:
httpdocs/wp-includes/formatting.php
~line: 1715
/**
* Convert one smiley code to the icon graphic file equivalent.
*
* Looks up one smiley code in the $wpsmiliestrans global array and returns an
* <img> string for that smiley.
*
* #global array $wpsmiliestrans
* #since 2.8.0
*
* #param string $smiley Smiley code to convert to image.
* #return string Image string for smiley.
*/
function translate_smiley($smiley) {
...
/**
* Convert text equivalent of smilies to images.
*
* Will only convert smilies if the option 'use_smilies' is true and the global
* used in the function isn't empty.
*
* #since 0.71
* #uses $wp_smiliessearch
*
* #param string $text Content to convert smilies from text.
* #return string Converted content with text smilies replaced with images.
*/
function convert_smilies($text) {
I'll show you the function first.
private var areaCollection:ArrayCollection;
private function generateAreaCollection():void
{
areaCollection = new ArrayCollection();
areaCollection.addItem({Areal: "Totalareal:", Verdi: int(totalArea * 100) / 100 + " kvm"});
areaCollection.addItem({Areal: "Hovedtakets areal:", Verdi: int(result.area* 100) / 100 + " kvm"});
//Lots of other stuff omitted (just more addItems).
}
As you see, the order i put the items in the ArrayCollection is Areal, then Verdi (area, value)
When i loop through the collection later, the order changes. Now it is Verdi then Areal (value, area).
Does anyone have an idea of what might be the problem?
It really ruins things when I pass it over to a PHP-script for table-making in html later.
(I have several different dynamic DataGrids that differs in size and "values", so I can't really point directly to f.ex "Areal" in my PHP-script)
And by the way, does anyone know how i can remove that pesky mx_internal_uid?
Raw objects in AS3 (Object class, or things defined by {} ), have no sorting. That is, the order is unpredictable. You're confusing two ideas here I think. The Areal and Verdi strings are keys within an object map. The array collection is a list composed of two such objects. So any sorting applied to the array collection will sort those objects, but not within the object.
So you need to refer to areaCollection.source[0].Areal to get "Totalareal". And areaCollection.source[1].Verdi to get int(result.area* 100) / 100 + " kvm"
If you do for(var s:String in areaCollection.source[0]) { } you will iterate twice, with the value of "s" being "Areal" and "Verdi" or vice-versa (e.g, order not guaranteed).
Make sense? If you need order, you can make the object an array instead ["Totalareal", (int(totalArea * 100) / 100 + " kvm")], and then access "Verdi" using [1].
P.s. not sure how to remove the mx_internal_id.
