I am using dojox.charting.Chart2D to display Graphs/ Charts in our Application .
My Timestamp data would be in this format 2005-06-29 08:05:00 .
I am using dojox.charting.Chart2D to display Charts .
Could anybody please let me know how to insert this TimeStamp Data into the addSeries Method of Chart2D ??
Or please let me know what is the appropiate way for inserting Timestamp Data into DOJO Charts ??
help me , my work has been struck .
I would do this on the server side following Dojox's addSeries method. I would assume you are wanting to plot an array of timestamps, otherwise there would be only one point on the chart. You could do something like this:
chart1.addSeries(
"Series 1",
[
// Your server code here
// series is an array of times
foreach($series as $v) {
echo date("Y-m-d : H:i:s", $v).", ";
}
// End server code
]
);

I have been trying to get the the Year and Month from the user and insert them into the database.
i am using input type month so that the user can send only the Year and the Month.
<input type="month" name="date_from"/>
<input type="month" name="date_to"/>
and this is my model
function setDateFromAttribute($value)
{
$this->attributes['date_from'] = \Carbon\Carbon::createDateFromFormat('Y-m', $value);
}
function setDateToAttribute($value)
{
$this->attributes['date_to'] = \Carbon\Carbon::createDateToFormat('Y-m', $value);
}
protected $fillable = [
'date_from',
'date_to',
];
and data is saved as 0000.00.00
the data type in my database for these two inputs is
timestamp
i do not know what i am doing wrong here. please help
I don't see createDateFromFormat as a valid Carbon method in the documentation https://carbon.nesbot.com/docs/
Likewise, there does not appear to be any createDateToFormat method.
Carbon::createFromFormat() returns a Carbon object, not a string or equivalent MySQL timestamp, so, assuming you change your code to be:
$this->attributes['date_from'] = \Carbon\Carbon::createFromFormat('Y-m', $value)->toDateTimeString();
It should provide the results you are looking for.

Sorry for the late reply couldn't find a solution that works within the model. tried your method which i have tried before with minor changes.
thanks a lot for trying to help me.. i found a method to complete this inside the controller which i will not recommend, but this was the best i was able to find which works and i was on a tight schedule.
'date_from' => isset($date_from[$key]) ? date('Y-m-d h:i:s', strtotime($date_from[$key])) : '',
'date_to' => isset($date_to[$key]) ? date('Y-m-d h:i:s', strtotime($date_to[$key])) : '',
the type timestamp accepts at least dates in full formats. as i know how i pass the data from blade to the controller i was able to add a date method and within it a strttotime method to convert my YY-MM into YY-MM-DD and the date that is inserted by default will be 01.
Is there any way to put a manual function inside a query in Laravel.
I've timestamp saved in string in DB. I want to convert timestamp from one timezone to another. All the timestamp is inserted in one time zone, and depending upon my user I fetch the timestamp and convert it into their timezone.
what I want to achieve is something like this..
$query = BlogCategory::select('merchant_id', userTime(added_at))
->where('site_id', $site_id)
->get();
userTime() function takes two parameter, the timestamp and the timezone and converts the timsestamp to time of the user.
I want to use userTime() function before fetching the data. I dont want to fetch the data first and then do foreach and so on.
I know I might be absolutely absurd but is there anything of this sort in Laravel?
Well you can achieved that using collection map
$query = BlogCategory::select('merchant_id', 'added_at')
->where('site_id', $site_id)
->get();
$dateAdded = $query->map(function ($data) {
// try this if error $data['merchant_id']
return array(
'merchant_id' => $data->merchant_id,
'added_at' => $this->userTime($data->added_at)
);
})
dd($dateAdded);
Read Collection documentation here: https://laravel.com/docs/5.8/collections
You should use the selectRaw statement and let your DB do this logic for you if you don't want to loop over the result set.
For example if your underlying database is MySQL you can use the CONVERT_TIMEZONE function and do something like this.
BlogCategory::selectRaw('merchant_id, CONVERT_TZ(added_at, "GMT", "MET") as added_at')
->where('site_id', $site_id)
->get();
There are few ways that I can do this using PHP but I could not find a way to do that using laravel specific way.
I have a time that is coming from database in below format: Y:M:s
ex: 05:15:00
This is what I want to do:
add 30 minutes to that date, according to above example result should be: 05:45:00
Below is my current code and I want to add 30min to $endTime:
//get database value according to selected date
$allocatedDateQuery = DB::table('appointments')->where('date', $request->date)->get();
//loop throug every record to get time
foreach ($allocatedDateQuery as $value) {
$time = $value->time;
$endTime = $time;
}
I just got a perfect solution from here.
Use Carbon extention to simply acheive that.
What you have to do is parse your time to Carbon object and then you can use addMinutes() to do that and then you can format() if you want:
foreach ($allocatedDateQuery as $value) {
$time = Carbon::parse($value->time);
$endTime = $time->addMinutes(30);
$allocateValidateMessage .= Carbon::parse($value->time)->format('H:i') . ' - ' . $endTime->format('H:i') . ' ';
}
Usually I use php's date, you can give this a try
Date("Y:M:s", strtotime("30 minutes", strtotime($value->time))
That is converting your time into a string, adding 30minutes to it and converting it to the date format of your desire
Since you said you are grabbing the date from the database I am assuming you are also using Eloquent to query from the database.
You can use Eloquent Mutator Method in your Database Modal Class to mutate the data like this:
public function getAppointmentsAttribute($value) {
return Date("Y:M:s", strtotime("30 minutes", strtotime($value->time)));
}
You can even add another attribute without mutating the original value using Attribute assignments as well. This method caches your query and reduces database calls. Since you do not need to run local loops on the record your code is much cleaner.
i'm just starting out with Dexie, and I seem to be coming unstuck.
I have a small database (less than 1000 rows), and i'm trying to delete each row one-by-one once I know that the row has been sent to a remote API.
I can also successfully save to the table (which is defined by an ID and a column storing a serialised object)
here's my code:
if (online) {
//we query the db and send each event
database.open()
let allEvents = database.events.toCollection()
let total = allEvents.count(function (count) {
console.log(count + ' events in total')
//a simple test to ensure we're seeing the right number of records
})
allEvents.each(function(thisEvent){
//push to remote API
console.log('deleting ' + thisEvent.id)
database.events.delete(thisEvent.id) //<= this doesn't seem to be working
})
}
All of this with the exception of the final delete statement.
Any ideas on how I should fix this? the important thing for me is to delete on a per-row basis.
thanks in advance!
I was experiencing the same problem, and the answer from Eugenia Pais wasn't working for me. So after some tests, I saw the trouble was with the type of the variable: I was using a string, but a number is needed, so this is how I solved it:
function removeRow (primaryKey) {
primaryKey = parseInt(primaryKey);
databaseName.tableName.where('primaryKey').equals(primaryKey).delete().then(function(deleteCount) {
console.log ("Deleted " + deleteCount + " rows");
}).catch(function(error) {
console.error ("Error: " + error);
});
So be aware you are using a number as argument.
The correct way to delete each row should be selecting the specific row and delete it:
database.tableName.where(indexId).equals(indexValue).delete();
The data type of the key is not a problem you could verify it in my example here: example
db.example.where('key').equals('one').delete();
Maybe you are trying to delete by a property that not is an index.
I am working on a project that it's a bit over my basic level of web development I am not able to understand how to get specific data from my SQL and show it follow by a button that will show the entire data of the specific row a small example how it has to look on my html its:
Name. Postcode telephone (button view more ).And the next row will be the same. Hope this it understandable I can't wait for an answer.
For the first part of your question here is how you take data from database with php and show it on the page. Read this Also there are a several way to do that, more example you can find here if you interested...
For second part of your question to show data on specific location on your page, you should't just echo data instead of that place your code in variable something like this:
if ($result->num_rows > 0) {
$myTable = "<table><tr><th>ID</th><th>Name</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
$myTable .= "<tr><td>" . $row["id"]. "</td><td>" . $row["firstname"]. " " . $row["lastname"]. "</td></tr>";
}
$myTable .= "</table>";
} else {
echo "0 results";
}
end then in your page i figured out it's organized as larger table just place variable $myTable where you want to be. Something like
<td class="">$myTable</td>
GL!
P.S. note that when you continue string for my table you have .= (dot equal) sign if you miss it it won't work as you expect..
