Angular-ui validation not working in model window - angularjs

Question

I am working on AngularJS with ui-grid. In the grid when i edit a row I am opening a modal window like this
$scope.editRow = function(row){
var modalInstance = $modal.open({
templateUrl : contextPath+ '/row/edit',
controller : 'EditController',
size : 'lg',
scope: $scope,
resolve : {
result : function() {
return row;
}
}
});
modalInstance.result.then(function() {
.......
});
}
and the model window gets open with the row details after calling Editcontroller default function. Until this point it is working fine.
Now i am trying to do the validation on the opened modal window using AngularUI and the validation is not working. Below is my UI page where the validation is not working
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title"></h4>
<h3 align="center">Edit Row Details</h3>
</div>
<div class="modal-body">
<form class="form-horizontal" name="myform" ng-submit="submitForm(myform.$valid)" novalidate>
<!-- Content Start -->
<div class="container">
<div class="row">
<div class="form-group required"
ng-class="{ 'has-error' : myform.name.$invalid && !myform.name.$pristine }">
<label for="name" class="control-label"> Name
</label>
<div>
<input type="text" name="myform.name" class="form-control input-sm"
ng-model="myform.name" placeholder="Name"
required />
<p ng-show="myform.name.$invalid && !myform.name.$pristine" class="help-block"> Name is required.</p>
</div>
</div>
</div>
<div class="row">
<div class="form-group">
<div>
<button type="submit" ng-model="myform.save" ng-disabled="myform.$invalid"
class="btn btn-primary" ng-click="edit(myform)">EDIT</button>
</div>
</div>
</div>
</div>
<!-- Content End -->
</form>
</div>
Somebody please help me how to do the validation. one more thing if i open the modal window normally the validation is working but i have the issue when i edit the row. I think this is a scope issue and the child scope is not getting bind. Your help is very much appreciable.

Answer 1

You don't need to include the form name in the name of the input, it's within a form so the input is bound to that form already. I'd also recommend binding your ng-model to another object on your scope (below I've used model) rather then the form itself.
You would write it like this.
<div class="row">
<div class="form-group required"
ng-class="{ 'has-error' : myform.name.$invalid && !myform.name.$pristine }">
<label for="name" class="control-label"> Name </label>
<div>
<input type="text" name="name" class="form-control input-sm"
ng-model="model.name" placeholder="Name"
required />
<p ng-show="myform.name.$invalid && !myform.name.$pristine" class="help-block"> Name is required.</p>
</div>
</div>
</div>
Also I'd change the ng-submit to the following
<form class="form-horizontal" name="myform" ng-submit="myform.$valid && submitForm()" novalidate>

Finally, I am able to find the solution
in EditController add below code
$scope.form={};
and your form should have form.myform like this
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title"></h4>
<h3 align="center">Edit Row Details</h3>
</div>
<div class="modal-body">
<form class="form-horizontal" name="form.myform"
ng-submit="submitForm(form.myform.$valid)" novalidate>
<!-- Content Start -->
<div class="container">
<div class="row">
<div class="form-group required"
ng-class="{ 'has-error' : form.myform.name.$invalid && !form.myform.name.$pristine }">
<label for="name" class="control-label"> Name </label>
<div>
<input type="text" name="myform.name"
class="form-control input-sm" ng-model="myform.name"
placeholder="Name" required />
<p ng-show="form.myform.name.$invalid && !form.myform.name.$pristine"
class="help-block">Name is required.</p>
</div>
</div>
</div>
<div class="row">
<div class="form-group">
<div>
<button type="submit" ng-model="myform.save" ng-disabled="form.myform.$invalid" class="btn btn-primary"
ng-click="edit(myform)">EDIT</button>
</div>
</div>
</div>
</div>
<!-- Content End -->
</form>
</div>
