MappingItemConverter

[Nexotap]

I posted the same in data-import-bundle. But that bundle looks quite abandoned. So here it again.

I'm trying to use MappingItemConverter. But I cant find it somewhere in the source. Can someone enlighten me, please?

Hey!

What do you mean exactly? The class is here.
In the actual master branch it was refactored and now it is a simple step.

If you give some more information, maybe i can help :-)

I'm sorry about my ignorance of this. Since I'm using Symfony, what I'm doing most of the time, is using symfony-bundles with composer. I'm not too aware of all this stuff. It seems, the bundle is not fetching the actual master branch.

Is there any need of that symfony bundle at all? Or is it easily possible without?
Maybe you can give me a short example of how I would do this?

Thank you in advance :)

Hey, yes the bundle is currently not compatible with the current master branch. But there are good new for you, you don't need the bundle.
Here is a short script:

$reader = new Reader\DbalReader($conn, 'SELECT * FROM users');
$writer = new Writer\CsvWriter(';', '"', fopen(__DIR__.'/test.csv', 'a+'));

$mapping = new Step\MappingStep();
$mapping->map('first_name', 'firstname');
$mapping->map('last_name', 'lastname');

$filter = new Step\FilterStep();
$filter->add(function($) { return $v['lastname'] !== 'Admin'; });

$workflow = new new Workflow\StepAggregator($reader);
$workflow->addStep($mapping);
$workflow->addStep($filter);
$workflow->addWriter($writer);

$workflow->process();

Thank you very much. Got it working now. There's one thing which is not clear to me. Why do I have to write the mapping with brackets like this:

$mapping->map('[first_name]', '[firstname]');

Would it not be sufficient to ommit the brackets, like you showed me in the code above?

Another thing which concerns me. Do you consider working with the master branch safe or should I stick with the stable? Alltough there's no Step there yet.

@Nexotap This by design, sorry i missed that 😢 .
We rely on the property-accessor component from symfony, and they use this convention.

To you second question: Generally i doesn't recommend to rely on the master branch, because if we change something on the core, your app will break.
You should always use a stable version, to ensure that your app will work with this branch.

@Baachi Don't worry, you are forgiven 😏. I'll still use the master branch, since I like Step stuff.

Anyway, thank you alot for the help and who knows, maybe the time comes I can help out in one other another way.
