I have domain object named Roll and on the list page i want to show the user all the Roll objects iterating through a list, sorted by entry date.
Here is the code i am using
[rollList: Roll.findAll(sort:"rollDate"){userid==uid}]
rollDate is a field inside the Roll object with data type java.util.Date
Any suggestion on why the output is not sorted by rollDate. When i iterate through the rollList on the gsp page it is not sorted.
Also, on the Roll domain object i have even put this code, but it's still not sorting.
static mapping = {
sort "rollDate"
}
Thank you.
Why aren't you using the dynamic finders?
Roll.findAllByUserid( uid, [ sort:"rollDate", order: 'desc'] )
should work.
The findAll( Map, Closure ) method appeared not a long time ago, perhaps it was not tested well...
You might need to use order in your query as well, then add order to it
[rollList: Roll.findAll(sort:"rollDate", order: 'desc'){userid==uid}]
After trying both the solutions mentioned it still didn't work. So i thought something might be wrong on the front end.
While researching more i found that since i was using jquery data tables it used to re order the sorting. The solutions i found was here
jQuery DataTable rows order
So both the answers above are correct. The issue was actually with jquery data tables.

I’m trying to create a new dataset type Powerapps Component (PCF). For the moment I am using it to display a view of the records that are available in an entity in Microsoft Dynamics CRM.
I wish to make the view sort itself when I click on the grid column headers (in a similar way that the default CRM grid view does). I'm trying to figure out how to apply a sort to the dataset so that I can refresh it as indicated by the documentation for the dataset.refresh() function:
Refreshes the dataset based on filters, sorting, linking, new column.
New data will be pushed to control in another 'updateView' cycle.
The dataset object does have a “sorting” property, but changing its value and then refreshing the dataset doesn’t seem to have any effect. After the refresh, the sorting property reverts to the value it had before I changed it.
In short, the click handler for the grid header does something like the following bit of code. The refresh gets done and my updateView() function gets called as expected but the sorting was not applied.
dataset.sorting = [{name: 'createdon', sortDirection: 1}];
dataset.refresh();
Any help on getting the dataset sorting to work would be appreciated.
I've been experimenting with PowerApps Component Framework a little bit recently and I can confirm that the following code won't be working:
dataSet.sorting = [ { name: "columnName", sortDirection: 0 } ];
However, I managed to get this one working for me:
dataSet.sorting.pop(); // you may want to clean up the whole collection
dataSet.sorting.push({ name: "columnName", sortDirection: 0 });
I haven't really figured out the reason of this behavior. The sorting array may be implemented as some form of observable collection in the background.
I hope this will guide you to a functioning solution.
The documentation is pretty abysmal here, but here is my best guess from putting a few different pieces of information together.
TLDR: I think there is some kind of extra method that needs to be called on the .sorting property, but I can't find out what it is called. Maybe something like:
dataset.sorting.setSorting({name: 'createdon', sortDirection: 1});
I think you're going to have to try a bunch of likely method names and see what works.
Background and links:
The only reference I could find to dataset.sorting was from here:
In this preview for canvas apps, only a limited set of filtering and sortStatus methods are supported. Filter and sort can be applied to dataset on primary type columns except for the GUID. Filter and sorting can be applied in the same way as in model-driven apps.To retrieve the dataset with filtering and sorting information, call
the methods in context.parameters.[dataset_property_name].filtering
and context.parameters.[dataset_property_name].sorting, then invoke
the context.parameters.[dataset_property_name].refresh().
So it seems that the .filtering and .sorting properties are handled similarly, and that there are some methods attached to them, and only some are supported. That is about as vague as they could make it...
I did find an example of how .filtering is used:
_context.parameters.sampleDataset.filtering.setFilter({
conditions: conditionArray,
filterOperator: 1, // Or
});
There is a brief reference to .setFilter() in the docs, as well as FilterExpression
There is a SortStatus reference, but it doesn't have any corresponding methods explicitly called out. It is possible that this is not yet a supported feature in the public preview, or the documentation is lacking and the name and syntax of the method you need to call on .sorting is not yet documented.
I am trying to do string replace on entries of a column inside a db table. So far, I have reached till here:
$misa = DB::table('mis')->pluck('name');
for($i=0;;$i++)
{
$misa[$i] = substr_replace("$misa[$i]","",-3);
}
The error I am getting is "Undefined offset:443".
P.S. I am not a full-fledged programmer. Only trying to develop a few simple programs for my business. Thank You.
Since it's a collection, use the transform() collection method transform it and avoid this kind of errors. Also, you can just use str_before() method to transform each string:
$misa = DB::table('mis')->pluck('name');
$misa->transform(function($i) {
return str_before($i, ':ut');
});
There are a few ways to make this query prettier and FASTER! The beauty of Laravel is that we have the use of both Eloquent for pretty queries and then Collections to manage the data in a user friendly way. So, first lets clean up the query. You can instead use a DB::Raw select and do all of the string replacing in the query itself like so:
$misa = DB::table('mis')->select(DB::raw("REPLACE(name, ':ut' , '') as name"));
Now, we have a collection containing only the name column, and you've removed ':ut' in your specific case and simply replaced it with an empty string all within the MySQL query itself.
Surprise! That's it. No further php manipulation is required making this process much faster (will be noticeable in large data sets - trust me).
Cheers!
I want to filter and then sort my ember records such that the null records for a column are returned first. I'm not much familiar with ember and have a rails back ground.
filteredByData = myLeads.filterBy('status', 'open').filterBy('doNotCall', false).filterBy('phoneValid', true)
filtered = filteredByData.sortBy 'last_dialed_at', 'last_name', 'first_name', 'id'
Right now, my records are getting ordered according to the id.
What i want is to implement the NULLS LAST/FIRST from sql or postgres in any query (such a s SELECT * FROM t1 ORDER BY c1 DESC NULLS FIRST here in my sort so i get the records such that the last_dialed_atnull records come first.
I know the same can be implemented in rails like
Foo.order('last_dialed_at DESC NULLS FIRST') but i have no idea for same in Ember
Any help will be appreciated. Thanks in Advance.
P.S: I'll try to create a ember twiddle meanwhile to explain myself better.
Although you can resort to a SortableMixin/ArrayProxy, those are lower-level APIs than you should really need to use. sortBy works fine for a single value, but I generally use computed.sort when I need to sort multiple things. Take a look at the code and link in this answer https://stackoverflow.com/a/46788377/334913 they should get you going.
One of the common ways Ember suggests doing things is to do computed properties for each step (or set of steps) as it makes it far easier to reason about.
So I would do something along the lines of:
filteredLeads: Ember.computed('leads', function() {
return filteredResultsHere;
}),
sortDefinition: [], // put your entries from your SortableMixin here
sortedFilteredLeads: Ember.computed.sort('filteredLeads', 'sortDefinition'),
I solved my issue by using the Ember.SortableMixin instead of sortBy. I ended up with the following code and this worked perfectly for me.
leads = Ember.ArrayProxy.createWithMixins Ember.SortableMixin, content: filteredByData, sortProperties: ['lastDialedAt', 'firstName', 'lastName', 'id'], sortAscending: true
I'm not sure or much aware why this worked and the fundamentals to an extent that i can explain this behaviour. If there's any explanation for same from anyone, please feel free to put your answer below and i'll accept it as the answer.
Thanks
This is not working as we discussed previously, for some reason and I have done is create some $vars for the uploaded file.
Code available here (Pastebin).
But never actually inserts anything
When doing a var_dump($csv_row) i get: bool(false)
var_dump($fh) shows: resource(89) of type (stream)
var_dump($insert_str) shows all 1700 records from the csv file (obviously too big to post on here)
So I’m guessing the while statement or the whole from if statement is wrong somewhere. Really really would appreciate some help on this, I need to get it working by tomorrow (monday)
You seem to be using the codeigniter database library wrong. I can see a
$this->db->set($insert_str);
but no $this->db->insert() to be found. The set() method only useful with an update() or insert() following it, See the docs, search for $this->db->set().
You either want to use the $this->db->insert_batch() (on the same doc page, unfortunately no direct links for sections) form and build up an array of arrays with your records (so you won't have to create a long sql string either).
Or you can use the $this->db->query() and just feed the $insert_str to it where you now call $this->db->set().
According to your question:
var_dump($insert_str) shows all 1700 records from the csv file
So i would rule out the possibility of the while loop or the if not working.
Put this code at the top of the controller or before reading csv file
ini_set('auto_detect_line_endings', true);
Check if this will work for you
I'm loading data using jQuery (AJAX), which is then being loaded into a table (so this takes place after page load).
In each table row there is a 'select' link allowing users to select a row from the table. I then need to grab the information in this row and put it into a form further down the page.
$('#selection_table').on('click', '.select_link', function() {
$('#booking_address').text = $(this).closest('.address').text();
$('#booking_rate').text = $(this).closest('.rate').val();
});
As I understand it, the 'closest' function traverses up the DOM tree so since my link is in the last cell of each row, it should get the elements 'address' and 'rate from the previous row (the classes are assigned to the correct cells).
I've tried debugging myself using quick and dirty 'alert($(this).closest(etc...' in many variations, but nothing seems to work.
Do I need to do something differently to target data that was loaded after the original page load? where am I going wrong?
You are making wrong assumptions about .closest() and how .text() works. Please make a habit of studying the documentation when in doubt, it gives clear descriptions and examples on how to use jQuery's features.
.closest() will traverse the parents of the given element, trying to match the selector you have provided it. If your .select_link is not "inside" .address, your code will not work.
Also, .text() is a method, not a property (in the semantical way, because methods are in fact properties in Javascript). x.text = 1; simply overrides the method on this element, which is not a good idea, you want to invoke the method: x.text(1);.
Something along these lines might work:
var t = $(this).closest('tr').find('.address').text();
$('#booking_address').text(t);
If #booking_address is a form element, use .val() on it instead.
If it does not work, please provide the HTML structure you are using (edit your question, use jsFiddle or a similar service) and I will help you. When asking questions like this, it is a good habit anyways to provide the relevant HTML structure.
You can try using parent() and find() functions and locate the data directly, the amount of parent() and find() methods depends on your HTML.
Ex. to get previous row data that would be
$('#selection_table').on('click', '.select_link', function(){
$('#booking_address').text = $(this).parent().parent().prev().find('.address').text();
});
Where parent stands for parent element (tr), then prev() as previous row and find finds the element.
Is there a demo of the code somewhere? Check when are you calling the code. It should be after the 'success' of AJAX call.
