I have a table that is created using ng-repeat. I want to add validation to each element in the table. The problem is that each input cell has the same name as the cell above and below it. I attempted to use the {{$index}}
value to name the inputs, but despite the string literals in HTML appearing correct, it is now working.
Here is my code as of now:
<tr ng-repeat="r in model.BSM ">
<td>
<input ng-model="r.QTY" class="span1" name="QTY{{$index}}" ng-pattern="/^[\d]*\.?[\d]*$/" required/>
<span class="alert-error" ng-show="form.QTY{{$index}}.$error.pattern"><strong>Requires a number.</strong></span>
<span class="alert-error" ng-show="form.QTY{{$index}}.$error.required"><strong>*Required</strong></span>
</td>
</tr>
I have tried removing the {{}}
from index, but that does not work either. As of now, the validation property of the input is working correctly, but the error message is not displayed.
Anyone have any suggestions?

Since the question was asked the Angular team has solved this issue by making it possible to dynamically create input names.
With Angular version 1.3 and later you can now do this:

Angular 1.3 also introduced ngMessages, a more powerful tool for form validation. You can use the same technique with ngMessages:
