Override the addToCart price

[Former Member]

Hi,

We need custom logic for the addToCart price, we have several price rows with an additional field, based on that field we know which price row we should use. However Hybris doesn't understand this custom logic, so we need to override it. But how can we override the addToCart price?

I already tried to override the class CommercePriceService with their methods getPriceFromProduct() and getWebPriceFromProduct() and that has influence on the base price, but it hasn't any influence on the addToCart price.

How should we handle this?

Thanks in advance.

Edit: I found the page https://wiki.hybris.com/display/release5/Extending+CommerceCartService where is explained that you can hook the addToCart mechanism. Ofcourse I could add this and call the afterAddToCart method to recalculate the prices. Is this the best way to solve this issue?

Edit2: Someone mentioned that I should override (and extend) the Europe1PriceFactory and than only override the method 'matchPriceRowsForInfo' and that should be enough. Is this the best solution to solve this?

I solved this problem by overriding the Europe1PriceFactory. First you should create your own PriceFactory and extend the Europe1PriceFactory and than you should override the current priceFactory in aN aftersessionevent.

Where is the AbstractEventDecorator?

[Former Member · Accepted solution]

How I can have retrieveChannelStrategy. We have only the setter and variable is private. setRetrieveChannelStrategy(RetrieveChannelStrategy retrieveChannelStrategy)

Please advice,

instead of AbstractEventDecorator we can use AbstractEventListener.
