I have this code suggested to me. I am trying to sum the stock_in_qty and stock_out_qty.
$warehouse1stocks = Warehouse1stocks::select(
"order_item_id",
Warehouse1stocks::raw('SUM(stock_in_qty) as stock_in_qty'),
Warehouse1stocks::raw('SUM(stock_out_qty) as stock_out_qty'))->groupBy('order_item_id')->get();
// dd($warehouse1stocks);
return view("warehouse1.index", compact("warehouse1stocks", $warehouse1stocks));
My problem is this error
I tried to look for an answer from other questions here and I think my code seems ok but why am i still having that error?
what do you think is the problem with my code? thanks in advance!
Instead of writing:
Warehouse1stocks::raw('SUM(stock_in_qty) as stock_in_qty')
write:
DB::raw('SUM(stock_in_qty) as stock_in_qty')
when defining the write expressions
use this one
$warehouse1stocks = Warehouse1stocks::select(
"order_item_id",
\DB::raw('SUM(stock_in_qty) as stock_in_qty'),
\DB::raw('SUM(stock_out_qty) as stock_out_qty'))->groupBy('order_item_id')->get();
// dd($warehouse1stocks);
return view("warehouse1.index", compact("warehouse1stocks", $warehouse1stocks));

I have a statement like "Animal Association" from the database. I want to get its short form. It means, only the first letter of each word like this "AA". In the blade file, I got the whole statement as follows,
<p>{{ $animal->user->club->name}}</p>
So, how can I get a short form of this name?
Thank You!
If you are using MySQL 8+, then a raw select with REGEXP_REPLACE should work here:
$users = DB::table('animals')
->select(DB::raw("SELECT REGEXP_REPLACE(name, '(\\w)\\w+\\s*', '$1')"))
->get();
This very common problem where we ran into, I can provide you a function that will solve your problem. I am sharing two solutions and you can use any of these solutions.
using function
You can use this function in your model and solve your problem.
public function getNameAbbreviate($string){
$abbreviation = "";
$string = ucwords($string);
$words = explode(" ", "$string");
foreach($words as $word){
$abbreviation .= $word[0];
}
return $abbreviation;
}
There is probably no one-line solution, the solution which I provided is readable and understandable.
using regex
This solution is easy to apply and in case you can't make the first method work then go with this.
<p>{{ preg_split("/\s+/", $animal->user->club->name) }}</p>
using regex we can get a direct solution but I personally don't like it or recommend it.
Is there a way to escape a "?" in a eloquent whereRaw Statement? (Using laravel 6.x)
example:
ExampleModel::whereRaw(' "table"."json_field"::jsonb ?| array[\'test\', \'test2\'] ')->get();
This gets sent to the db as
where "table"."json_field"::jsonb $1| array['test', 'test2']
And well, thats not what i wanted to query...
Tried with '\?', put it in a binding (Laravel doc) - still no success.
Also i didn't find a reference in the docs ...
In my Usecase i want it to compare a json object with the psql comparing "?|" (Postgres Doc)
Thanks in advance!
the question is pretty old but my answer might help anyway.
The solution is very simple: just escape the questionmark with another questionmark.
The code of your example would look like this:
ExampleModel::whereRaw(' "table"."json_field"::jsonb ??| array[\'test\', \'test2\'] ')->get();
This solution has been tested with Laravel 7.28.3.
Didn't test but try using PDO:
$whereRaw = DB::connection()->getPdo()->quote(' "table"."json_field"::jsonb ?| array["test", "test2"] ');
ExampleModel::whereRaw($whereRaw)->get();
Well, didn't find an answer, but a workaround:
Don't use the question mark operators!
Instead i went for the named function. I found the named function via
SELECT
oprname,
oprcode || '(' || format_type(oprleft, NULL::integer) || ', '
|| format_type(oprright, NULL::integer) || ')' AS function
FROM pg_operator
WHERE oprname = '?|';
( Found there: big thanks to this guys post!)
So my Eloquent query now looks like:
ExampleModel::whereRaw('jsonb_exists_any("table"."json_field"::jsonb, array[\'test\', \'test2\'])')->get();
At least its working ¯\_(ツ)_/¯
Is it possible to set points in initials?
For example to change MAW into M.A.W.
I tried keep_before, but it doesn't work.
?keep_before(" ")+". "}
Result: MAW.
Please help.
You could do it like:
${'MAW'?replace('','.')[1..]}
'MAW'?replace('','.') will result in .M.A.W., which you can "substring" by using the range [1..].
See
https://freemarker.apache.org/docs/ref_builtins_string.html#ref_builtin_replace
https://freemarker.apache.org/docs/dgui_template_exp.html#dgui_template_exp_stringop_slice
It's easiest to do with regular expressions: ${initials?replace('.', '$0.', 'r')}. It's maybe nicer if you wrap this into a #function though (<#function dotify(s)><#return s?replace('.', '$0.', 'r')></#function>, and then ${dotify(initals)}), especially if you need to do this on multiple places.
If your letters are in name try:
<#list 0..(name?length-1) as idx>${name[idx]}.</#list>
I am trying to do this route trick:
$route['cp/roles/:num'] = "cp/roles/index/:num";
but it doesn't work :(
please help me!!
advanced thanks .
According to the documentation on URI Routing:
$route['product/(:num)'] = "catalog/product_lookup_by_id/$1";
“A URL with "product" as the first segment, and a number in the second will be remapped to the "catalog" class and the "product_lookup_by_id" method passing in the match as a variable to the function.”
So, for your particular instance, you would do the following:
$route['cp/roles/(:num)'] = "cp/roles/index/$1";
You could try
$route['cp/roles/:num'] = "cp/roles";
and then instead of passing a variable in your function you use
$this->uri->segment(3);
or the number that correspond to the segment.

It was just that my framework used was sanitizing all GET,POST requests.
Then removed those function that was causing the function and job done .
function sanitize($data)
{
$data = trim(strip_tags($data, "<a><b><strong><em><i><u><br><h3><h4><h5>"));
return $data;
}
