QUESTION
During development of SPA, hmr works great.
However, when published, hmr should not be running. Yet it is, and it produces a stream of 404 errors. Why is this? I don't see what I am doing wrong.
When I package for production, this is the command line (I am running this from the Visual Studio Task Runner):
...ANSWER
Answered 2018-Jun-11 at 12:15Please have a detailed look at the path which is throwing 404 (page not found). I guess this is often the issue with relative path.
QUESTION
I have this entity which includes the validation rules. It works. But it seems that maybe the Entity is not the best place to store such rules, because if I have a list of 100 entities, that code is run 100 times which seems unnecessary.
So it seems to me that a better place to keep the rules is in the repository. I have a repository for each entity, and it is a singleton.
But the question is how to do that?
...ANSWER
Answered 2018-May-12 at 18:55There are several kinds of validation to consider.
First is formal validation that has to be met for any entity or value to even be processed. Like "field name is required in this fieldset". Or "name must be not empty". And so on. This validation logic belongs to factories or entity/value constructors and doesn't need external calls.
Another type is checking business rules with regards to the current state of the system. For example "you cannot add routing rule that would make routing ambigous". You can put this logic inside domain services, if it involves more than a single entity/aggregate. Or you can put it in entity, provided that you call it from application layer with all needed external data at hand to make up a validation decision.
At last, there are rules at the DB level that are meant to preserve data consistency. These match naturally to DB constraints and belong to repositories.
So, in your case it seemes to be OK to put it into an entity constructor.
