Super Simple View Engine : #Each fail to render - nancy

To handle book creation post request, I have a handler likes below:
Post ["/edit"] = parameters => {
var book = this.Bind<Book>();
book.Id = new ObjectId(this.Request.Form["Id"]);
if(book.Id == null){
return Response.AsRedirect("/books");
}
var result = this.Validate(book);
if(result.IsValid){
bookRepository.Update(book);
return Response.AsRedirect("/books");
}else{
dynamic model = new DynamicDictionary();
model.Book = book;
var errors = new List<string>();
foreach(var key in result.Errors.Keys){
foreach(var value in result.Errors[key]){
errors.Add(string.Format("{0} - {1}", key, value));
}
}
model.ErrorMessages = errors;
return View ["book_edit.html", model];
}
};
And the book_edit.html:
<html>
<head>
<title>Edit book</title>
</head>
<body>
<h2>Edit book</h2>
<p>
Book listing
</p>
<h4>Validation Errors</h4>
#Partial['book_edit_error.html', Model.ErrorMessages];
<ul style="color:red">
#Each.ErrorMessages
<li>#Current</li>
#EndEach
</ul>
<form method="POST" action="/books/edit">
<table>
<tr>
<td>Name: </td>
<td>
<input type="text" name="Name" value="#Model.Book.Name"/>
<input type="hidden" name="Id" value="#Model.Book.Id"/>
</td>
</tr>
<tr>
<td>Author: </td>
<td><input type="text" name="Author" value="#Model.Book.Author"/></td>
</tr>
<tr>
<td>Description: </td>
<td><input type="text" name="Description" value="#Model.Book.Description"/></td>
</tr>
<tr>
<td><input type="submit" value="Save"/></td>
</tr>
</table>
</form>
</body>
And the #Each statement did work as expected:
I tried many times, but it simply didn't work, even when I tried to use #Partial.
But when using #Each with List model (not #Each.Properties, it worked.

try DynamicDictionary
dynamic model = new DynamicDictionary();
change to ExpandoObject
dynamic model = new ExpandoObject();
maybe work, good luck!

Please check the tutorial from here.
For your reference use following code and check the codepen to here.
In template
<tr ng-repeat="user in users">
<td>
<span ng-if="!user.editFlag">{{ user.fName }}</span>
<input ng-if="user.editFlag" ng-model="user.fName"/>
</td>
<td>

</td>
<td>
<button class="w3-btn w3-ripple" ng-click="deleteUser($index)">Delete</button>
</td>
</tr>
In your controller
// edit data
$scope.editUser = function (index) {
if($scope.users.length){
// its checking with your edit flag to save or edit
$scope.users[index].editFlag = !$scope.users[index].editFlag;
}
};
// Delete data
$scope.deleteUser = function (index) {
// Remove from main records (using index)
if($scope.users.length){
$scope.users.splice(index, 1);
}
};
Please check this sample to here.
Hopes this will help you !!
These changes will make addUser functionality work
$scope.addUser=function(index){
if(index){
$scope.users[index].fName=$scope.fName;
$scope.users[index].lName=$scope.lName;
}
else{
$scope.users.push({
'fName':$scope.fName,
'lName':$scope.lName,
});
}
$scope.editMode=false;
$scope.fName='';
$scope.lName='';
}
$scope.editUser=function(index){
$scope.editMode=true;
$scope.editIndex=index;
$scope.fName=$scope.users[index].fName;
$scope.lName=$scope.users[index].lName;
}
$scope.deleteUser=function(index){
$scope.users.splice(index,1)
}

Angularjs condition for Saving and Updating

I have one div with two fields.For first time if no records are there i want to save it .Right now it is happening.After that i am displaying the data.But if i change the data and update it is adding new row with updated data instead of updating same row.
Here is my html
<div class="col-xs-12 col-sm-12 col-md-12"
<tbody>
<tr role="row" class="even" data-ng-repeat="infraitem in
allInfraitemsByType">
<td><strong>{{infraitem.name}}</strong></td>
<td><input type="text"
name="requiredseat" data-ng-model="infraitem.requiredseat"></td>
<td>
<input type="text" name="available" data-ng-
model="infraitem.available"></td>
<td class="text-center"><button type="submit" class="btn GreenBtn"
data-ng-click="saveInfrastructureDetails(infraitem)"><span
class="glyphicon glyphicon-ok"></span>Save</button></td>
</tr>
</tbody>
</div>
Here is the controller.js
$scope.saveInfrastructureDetails = function(infraitem){
AdminCollegeService.saveInfrastructureDetails(infraitem).then
(function(response)
{
if(response.data=="success")
{
$scope.infraitem = {};
$scope.successmessageinfra="Infra Structure Details Saved";
});
}
Can anyone tell how to update same row if data is already present instead of adding new record.
make sure $scope.saveInfrastructureDetails function is hitting
make sure $scope.saveInfrastructureDetails is update the data to database or insert the data.
But the main think is
make sure are you using form tag for inserting records, if yes then change your update button type type="submit" to type="button"
This below sample like a key. I am saving and updating data with a array.
EDIT
angular.module("test",[]).controller("testCont", function($scope)
{
$scope.testArray =[{id:1,name:"Me"},{id:0,name:''}];
$scope.Save=function(data)
{
if(data.id == 0)
{
data.id=2;//instert code
}
else
{
return false;// you can call your update code
}
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="test" ng-controller='testCont'>
<table>
<tr ng-repeat="testobject in testArray">
<td>Name {{testobject.id}}</td>
<td>
<input type="text" ng-model="testobject.name" />
</td>
<td><input value="save" type="button" ng-click="Save(testobject)" /></td>
</tr>
</table>
</div>

Edit function is not properly working in angular JS

When I add any data I am getting values in text box instead of getting it in span.And also after the data gets added I am getting done button instead of getting Update button.Find my full code here:https://jsfiddle.net/GowthamG/jL5oza04/
Is there any error?
<script type="text/javascript">
var app=angular.module("mainapp",[]);
app.controller('mycontrol',function($scope){
$scope.filters=[];
$scope.add=function(filter){
$scope.filters.push(filter);
$scope.filter={};
};
$scope.update = function (index) {
$scope.editing = $scope.filters.indexOf(index);
};
<table border="2">
<tr>
<td>FirstName</td>
<td>LastName</td>
<td>Fees</td>
<td>E-Course</td>
</tr>
<tr ng-repeat="filter in filters track by $index">
<td><span ng-hide="update">{{filter.fname}}</span>
<input type="text" ng-show="update" ng-model="filter.fname">
</td>
<td><span ng-hide="update">{{filter.lname}}</span>
<input type="text" ng-show="update" ng-model="filter.lname">
</td>
<td><span ng-hide="update">{{filter.ffees}}</span>
<input type="number" ng-show="update" ng-model="filter.ffees">
</td>
<td><span ng-hide="update">{{filter.eroll}}</span>
<input type="text" ng-show="update" ng-model="filter.eroll">
</td>
<td>
<button ng-hide="update" ng-click="update = true; update($index)">Update</button>
<button ng-show="update" ng-click="update = false">Done</button>
</td>
<td>
<button ng-click="remove($index)">Remove</button>
</td>
</tr>
</table>
You have to initialize the value of $scope.update in your add functionality to hide the inputs. Now the values will be shown in a span with update button.
$scope.add=function(filter){
$scope.filters.push(filter);
$scope.update=false;
};

how to write function to target specific variable for ng disable that inside ng repeat?

I'm trying to build todo list app in angular. When you add new item, it will add to input box(by default, i set it to disabled) inside the table and also add Edit link next to that input. Once i click on the Edit, the input box will enable. ( i got it working with this code (Edit).
My question is how to replace ng-click="editable=!editable" with ng-click="edit()". I tried to write that Edit function, but i can't get it to work. Please help.
My code on jsfiddle
Thanks so much.
<body ng-app="shoppingList">
<div ng-controller="mainController">
<h1>My Shopping List</h1>
<form class="form-inline" ng-submit="addItem()">
<div class="form-group">
<input type="text" ng-model="newItem">
</div>
<input type="submit" value="Add">
</form>
<div>
<table>
<thead>
<tr>
<th>Item</th>
<th>Edit</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="item in items track by $index">
<td><input ng-disabled="!editable" type="text" value="{{item}}"></td>
<td ng-click="editable=!editable">Edit</td>
</tr>
</tbody>
</table>
</div>
</div>
<script>
(function(){
var app = angular.module('shoppingList',[]);
app.controller('mainController',function($scope){
$scope.items=[];
$scope.addItem = function(){
$scope.items.push($scope.newItem);
};
$scope.edit = function(){
// i need to move editable=!editable into this function
// but i don't know how to do that
}
});
}());
</script>
You could save the editable property of the todo item, and then us it like this.
$scope.addItem = function(){
$scope.items.push({text: $scope.newItem,editable:false});
};
$scope.edit = function(item){
item.editable = !item.editable;
console.log(item)
}
$scope.save = function(item){
console.log("saved")
item.editable = !item.editable;
}
html
<tr ng-repeat="item in items track by $index">
<td><input ng-disabled="!item.editable" ng-blur="save(item)" type="text" value="{{item.text}}"></td>
<td ng-click="edit(item)">Edit</td>
</tr>
I think this is simplest one, but there is always a better approach. Let us know. What is ngBlur

How to delete row from table in angularjs

Now I need to delete row(s) depends on it is selected or not. But how can I access $index in the control for each selected row?
my code is here:
<div ng-app="appTable">
<div ng-controller="Allocation">
<button ng-click="add()"> Add </button>
<button ng-click="remove()">remove</button>
<table>
<th>
<td>S.No</td>
<td>Name</td>
<td>Dept</td>
</th>
<tr ng-repeat="data in dataList">
<td><input type="checkbox" ng-model="delete"/>{{$index}}</td>
<td> <input type="text" ng-model="data.name"/></td>
<td><input type="text" ng-model="data.dept"/></td>
</tr>
</table>
</div>
</div>
var app = angular.module("appTable",[]);
app.controller("Allocation",function($scope) {
$scope.dataList = [{name:'lin',dept:'b'},{name:'test',dept:'aaa'}];
$scope.add = function(){
var data = {};
data.name ='' ;
data.dept ='';
$scope.dataList.push(data);
}
var deletes=[];
$scope.delete=false;
$scope.remove = function(){
console.log(deletes);
angular.forEach($scope.delete,function(v){
if(v==true){
deletes.push($index);*How can I get the $index for selected row*
console.log(deletes);
}
});
angular.forEach(deletes,function(v,k){
$scope.dataList.splice(v, 1);
})
}
});
Now I can add the row which match the requirement, but my issue is user have to check the checkedbox in the row which they want to delete and then click delete button to delete them. for example, they can check the first and third row to delete and only keep second row.
<div ng-app="appTable">
<div ng-controller="Allocation">
<button ng-click="add()"> Add </button>
<button ng-click="remove()">remove</button>
<table>
<th>
<td>S.No</td>
<td>Name</td>
<td>Dept</td>
</th>
<tr ng-repeat="data in dataList">
<td><input type="checkbox" ng-model="data.isDelete"/>{{$index}}</td>
<td> <input type="text" ng-model="data.name"/></td>
<td><input type="text" ng-model="data.dept"/></td>
</tr>
</table>
</div>
</div>
var app = angular.module("appTable",[]);
app.controller("Allocation",function($scope) {
$scope.dataList = [{name:'lin',dept:'b'},{name:'test',dept:'aaa'}];
$scope.add = function(){
var data = {};
data.name ='' ;
data.dept ='';
$scope.dataList.push(data);
};
$scope.remove = function(){
var newDataList=[];
angular.forEach($scope.dataList,function(v){
if(!v.isDelete){
newDataList.push(v);
}
}); $scope.dataList=newDataList;
};
});

You might need to add the following in your ng-repeat directive :
<tr ng-repeat="data in dataList track by $index">
and then use $index for deletion.
you can get more informations about this here from the official angular documentation.
Replace
<input type="checkbox" ng-model="delete"/>
by
<input type="checkbox" ng-model="data.toBeDeleted"/>
Then, on the click of the button, remove all the data which have a truthy toBeDeleted attribute from the array.
