How can we upload larger files? let's say more than 4GB? with livewire, since it stores the temp file locally first. Any idea?

Hi, im getting a ''No property found for validation: [ColumnsToMap.id]'' hope you can help me out.

public function rules() { $columnRules = collect($this->requiredColumns) ->mapWithKeys(function ($column) { return ['ColumnsToMap.' . $column => ['required']]; }) ->toArray();

1    return array_merge($columnRules, [
2
3        'file' => ['required', 'file', 'mimes:csv', 'max:51200'],
4
5    ]);

Is ColumnsToMap really in capital?

Instead of turning columnsToMap into a collection, mapping and using toArray, you could just use: array_fill_keys($this->columnsToMap, ‘’);

Can we use another file extension (xlsx,xls,ods) to import with LeagueCSV? I investigated and seems to me we can't ((. Maybe it possible to add this functionality by adding adapterÑŽ If we have other mime type (not CSV) then use another lib or smth like that)?

I have an issue: in CsvImporter.php in rules() method I try to define rule for file: 'file' => ['required', 'mimes:csv,xlsx,xls,ods', 'max:51200'] (the same as in cource), but this rule accept all mime type except csv ))). Anyone has an idea? P.S.: I use Ubuntu 20.04, Laravel 7 and php 7.4.

I find the answer: just add txt to mime types ---> 'mimes:csv,txt,xlsx,xls,ods',

Quick Tip:

If you want to make an invokable controller, you may pass i flag into the artisan command.

An example:

1php artisan make:controller CustomerIndexController -i

or

1php artisan make:controller CustomerIndexController --invoke

Any ideas about how to auto detect the CSV format?

My CSV is splitted with ";" so I had to set in readCsv method

$csv->setDelimiter(';');

You can use the static Info-class that are in the League package

1$delimiters = Info::getDelimiterStats($csv, [',', ';'], 2);
2if ($delimiters[';'] > 0)
3    $csv->setDelimiter(';');

If I find any ; as delimiters, I set that as the default.
