Sylius定制模型与图像

Question

I followed those recipes to:

1. Create a custom model
2. Add images to this custom model

I detected some things that don't happens like the recipes say, but once I have my custom model working, with the forms, the grid, the validation, the form extended to allow upload images... I got this error after send the form of creating a new object:

An exception occurred while executing 'INSERT INTO app_designer_image (type, path, owner_id) VALUES (?, ?, ?)' with params ["avatar", null, 2]:

I can't find the way to upload an image. Following the recipe, I defined a Image Upload Service listener, listening to the sylius.designer.pre_create and sylius.designer.pre_update but those events are never triggered, and when the image is going to be persisted, always fail because the path is not defined...

Any clue of what can be happening?

Answer 1

OK, I found the problem. There was a misconfiguration for the event listener, I attach the listener to the wrong event.

My mistake was follow strictly all the steps in this recipe. The problem is that the recipe is based on an extended version of an existing model, and the name of the events for a custom model is prepended by app. instead of sylius..

So, the event in the example is sylius.shipping_method.pre_create and mine is not sylius.designer.pre_create but app.designer.pre_create.

Once I fixed this everything starts to work as expected.
