I am having problems for implementing a simple server side form validation using angular 2.
given the following scenario:
{field: error}
e.x, if login and password are empty response is: {login: 'required', password: 'required'}Once it is submitted I have the response from server but I don't know how to update the state of each ngModel bound to a view control element to show it in the UI
It is a very common scenario and I am surprised that I am experiencing so many troubles of finding a proper documentation. (client validation is very well explained on the other hand)
Any help appreciated! Cheers :)
I have been looking all over the internet for server-side validation models, and i haven't find any official documentation, but instead, i got some useful articles - one of them from Stack Over~ - which may help you a little. I have not tested yet, still looking for infos and maybe you have already found an answer for your problem. Anyway, here is a short list with articles about server-side validations using different API:
