I'm struggling with some of the formatting for parameters inside the recurrenceRule when trying to create a new event with Expo Calendar. I can't seem to find any robust recurrence examples in the docs or anywhere else for that matter. One specific thing I'm struggling is daysOfTheWeek, where I'm trying to pass multiple days but I'm not even sure if you can.
Does anyone have a good working example of the recurrenceRule in action?
After struggling with this myself I found that if you look up types in your Calendar.d.ts file it should give you the required structure of the recurrenceRule.
export declare type RecurrenceRule = {
frequency: string
interval?: number // #default 1
endDate?: string | Date
occurrence?: number
daysOfTheWeek?: DaysOfTheWeek[]
daysOfTheMonth?: number[]
monthsOfTheYear?: MonthOfTheYear[]
weeksOfTheYear?: number[]
daysOfTheYear?: number[]
setPositions?: number[]
};
So if your use case is like mine and you just want the event to occur only once something like this will work: recurrenceRule: {frequency: 'DAILY', occurrence: 1} I think. Expo-documentation says recurrence rule can be set to null, but this throws an error. Hope this helps!

I'm making use of the datepicker from Element Ui where the user can select a range in dates. When the user fills in the datepicker, this is what I get back: ['2018-01', '2019-02'] . So just an array with two String elements. NOT a Date() object.
When dynamically outputting this to the user, I would like to show it as: January 2018 - February 2019
I got it somewhat working in my project but the code just really sucks and also doesn't work properly either. Checkout this gif of my current project and somewhat desired result. I was wondering if someone knows a good and easy way of achieving my desired result without too much hassle. I cannot use methods like toLocaleDateString() because it isn't a Date() object. I've got my code working in a Codesandbox. If any if you guys knows a solution feel free to edit the listed Codesandbox, I would highly highly appreciate it!
In the Codesandbox I got a computed property formateDate. The basic idea of the computed property is to cut the elements of the array I get back from the datepicker before and after the - effectively giving me the first & second month and first & second year. That data I store in these variables:
let monthOne;
let monthTwo;
let yearOne;
let yearTwo;
Since I get the months back as '01' and '02' for example, I created an array of objects to transform the '01' and '02' to January and February with a for loop. I then store the result in a new variable with:
displayDate = monthOne + ' ' + yearOne + ' - ' + monthTwo + ' ' + yearTwo;
Lastly, I tried to store that result into the timeperiodDisplayString at the correct index in the experience array of objects. Anyway, I'm probably overcomplicating this way to hard so I would REALLY appreciate any help with this.
Maybe you could map over the result from the datepicker component to create an array of Date objects. So you can use toLocaleDateString()
Something like this should work:
['2018-01', '2019-02'].map((date) => {
const split = date.split('-');
return new Date(split[0], +split[1] - 1);
});
You can use parse() function from javascript.
var d = Date.parse("2019-01");
console.log(new Date(d));
I am trying to create a calendar view in which there are events displayed with start and end times on one label. Something like:
2:30pm - 4:30pm
My model has a SimpleObjectProperty<LocalTime> for each of these times. I know that I could concatenate these by doing something like:
label(Bindings.concat(model.startTime, " - ", model.endTime))
But I would still need formatting for each time. Knowing how to do this would certainly help me in the future with other equally complex binding transformations. Or would it just be easier to attach listeners to each time property that would update the label text?
I think I found my own answer, but anyone can feel free to let me know if this is good practice or not.
root {
...
val timeFormat = DateTimeFormatter.ofPattern("h:mma")
label(stringBinding(model.startTime, model.endTime) {
val startTime = model.startTime.value
val endTime = model.endTime.value
"${startTime.format(timeFormat)} - ${endTime.format(timeFormat)}"
})
...
}
I am working on my own directory for my purchases of cryptocurrencies.
I am getting prices of BTC, ETH, and LTC via API, then I created a component for each of my punched coin, so then I want to calculate current price (ownedCoins * currentPrice).
So in my $root I have { eth: 324.233, btc: 2211.43, ltc: 41.341 }
Here is where I want to calculate it:
self.eur = response.data.sum[0].quantity * this.$root.ltc;
But I want to make this dynamic, so what I want to do is to create a dynamic variable. Something like that: self.eur = response.data.sum[0].quantity * this.$root.{this.coinName};
How would I do that?
I would read the State Management part of the VueJS docs then checkout the Vuex docs. Once your data store get even mildly more complex your method of managing it with your sample code will become overwhelming.
Your question doesn't have anything to do with vue, but just plain javascript. To access object variables in javascript you have 2 ways, using the dot notation or bracket notation (I call it array notation):
const car = { wheels: 4, seats: 5, horsepower: 145 };
console.log(car.wheels);
console.log(car['wheels']); //same result
So
this.$root[this.coinName];
will give you the result you are looking for.
I need to know can there be a tooltip populated with data from database to be displayed in the tooltip.
something like the tooltip should contain
name stauts
abc active
xyz active
pqr active
name and status are retrived from db
I need this tooltip onmouseover, am using CJSON decoded to render the content
i did go google but hardly did find that i would throughly understand and implement.
can anyone out there has any ideas for what am looking.
There is a extension named yii-bootstrap, which described clearly here.
For using tooltip easily in this extension, just look here.
I use cluetip for this. Its not related to Yii but will give you some idea :
JS
function renderInfoTips(opts){
var elements=$('#'+opts.form).get(0).elements;
for(i=0; i<opts.tips.length;i++){
$(elements[opts.tips[i].field]).parent().prepend(opts.tips[i].tip);
}
var clue_opts={arrows:true,splitTitle: '|',closePosition: 'title',sticky:true,dropShadow:false,mouseOutClose:true,
onShow:function(ct, ci){
if(!$.browser.webkit) $(ct).css('top',$(ct).position().top- 30+'px');
}
}
$('#'+opts.form).find(".infotip").cluetip(clue_opts);
}
PHP
function setInfoTipsJavascript($form_id,infotips){
if (count($this->infotips) <1 ) return '';
//get all tip names
$names_csv=join(',',array_keys(infotips));
//get tips details from db
$query="select name, description from infotips where FIND_IN_SET(name ,'$names_csv')";
//run the query, in Yii you have to use InfoTipsModel , I have skipped that portion
//$infotipS , lets say this is query object
$tips=array();
while($tip=$infotipS->Assoc()){
$this->infotips[$tip['name']]['tip']="<a href='javascript:void(0)' class='infotip' title='|{$tip['description']}'> </a>";
$tips[]=$this->infotips[$tip['name']];
}
$tips=json_encode($tips);
$script="\nrenderInfoTips({\"form\":'{$form_id}', \"tips\":{$tips}});\n\n";
echo $script;
}
I am sharing this hoping this will give u some idea. Its obvious you have to : create infotips table, a model for that, and create a widget etc to fetch infotips related to your form fields . As someone suggested, if you are using Bootstrap, you have better way to do that.
I was wondering how I would go about checking to see if a table contains a value in a certain column.
I need to check if the column 'e-mail' contains an e-mail someone is trying to register with, and if something exists, do nothing, however, if nothing exists, insert the data into the database.
All I need to do is check if the e-mail column contains the value the user is registering with.
I'm using the RedBeanPHP ORM, I can do this without using it but I need to use that for program guidelines.
I've tried finding them but if they don't exist it returns an error within the redbean PHP file. Here's the error:Fatal error: Call to a member function find() on a non-object in /home/aeterna/www/user/rb.php on line 2433
Here's the code that I'm using when trying this:
function searchDatabase($email) {
return R::findOne('users', 'email LIKE "' . $email . '"');
}
My approach on the function would be
function searchDatabase($email) {
$data = array('email' => $email);
$user = R::findOne('users', 'email LIKE :email, $data);
if (!empty($user)) {
// do stuff here
} // end if
} // end function
It's a bit more clean and in your function
Seems like you are not connected to a database.
Have you done R::setup() before R::find()?
RedBeanPHP raises this error if it can't find the R::$redbean instance, the facade static functions just route calls to the $redbean object (to hide all object oriented fuzzyness for people who dont like that sort of thing).
However you need to bootstrap the facade using R::setup(). Normally you can start using RB with just two lines:
require('rb.php'); //cant make this any simpler :(
R::setup(); //this could be done in rb.php but people would not like that ;)
//and then go...
R::find( ... );
I recommend to check whether the $redbean object is available or whether for some reason the code flow has skipped the R::setup() boostrap method.
Edited to account for your updated question:
According to the error message, the error is happening inside the function find() in rb.php on line 2433. I'm guessing that rb.php is the RedBean package.
Make sure you've included rb.php in your script and set up your database, according to the instructions in the RedBean Manual.
As a starting point, look at what it's trying to do on line 2433 in rb.php. It appears to be calling a method on an invalid object. Figure out where that object is being created and why it's invalid. Maybe the find function was supplied with bad parameters.
Feel free to update your question by pasting the entirety of the find() function in rb.php and please indicate which line is 2433. If the function is too lengthy, you can paste it on a site like pastebin.com and link to it from here.
Your error sounds like you haven't done R::setup() yet.
My approach to performing the check you want would be something like this:
$count = count(R::find('users', 'email LIKE :email', array(':email' => $email)));
if($count === 0)
{
$user = R::dispense('users');
$user->name = $name;
$user->email = $email;
$user->dob = $dob;
R::store($user);
}
I don't know if it is this basic or not, but with SQL (using PHP for variables), a query could look like
$lookup = 'customerID';
$result = mysql_fetch_array(mysql_query("SELECT columnName IN tableName WHERE id='".$lookup."' LIMIT 1"));
$exists = is_null($result['columnName'])?false:true;
If you're just trying to find a single value in a database, you should always limit your result to 1, that way, if it is found in the first record, your query will stop.
Hope this helps
