The validation function returns {error, [ErrorMessage*s*]} - correct if u
have only one error
It returns {error, [Error1, Error2, ..., ErrorN]} in general
validation_tests() -> [
{fun()-> false end, <<"email">>},
{fun()-> false end, <<"password">>},
].
case ....:save() of
{ok, _} ->
{error, E} -> {render_other, [{action,"show"}], [{errors, E}]} % or {json,
[{errors, E}]}
end
On frontend don't forget to check name against array of errors, so this
will not work if we consider given above case {% if email == errors %}
has-error {% endif %}
I use custom tag for this {%if errors|has:"email"%}has-error{%endif%}
has(undefined,_)->false;
has([],_)->false;
has(Errors,Key)->has(Errors,Key,false).
has(_,_,true)->true;
has([],_,Res)->Res;
has([H|T],Key,_)->has(T,Key,H=:=Key).
