Why the data is not populated ?
Jul 8 2016 10:08 AM
My problem now is that the hard coded data is not being populated.
And I'd like to know why.
In this class - BookInitializer, the author has hard-
coded an Author name Jamie Munro:
using
System;
using
System.Collections.Generic;
using
System.Linq;
using
System.Web;
using
BootstrapIntroduction.Models;
using
System.Data.Entity;
namespace
BootstrapIntroduction.DAL
{
public
class
BookInitializer : DropCreateDatabaseIfModelChanges<BookContext>
{
protected
override
void
Seed(BookContext context)
{
var author =
new
Author
{
Biography =
"..."
,
FirstName =
"Jamie"
,
LastName =
"Munro"
};
var books =
new
List<Book>
{
new
Book {
Author = author,
Description =
"..."
,
ImageUrl =
"http://ecx.images-amazon.com/images/I/51T%2BWt430bL._AA160_.jpg"
,
Isbn =
"1491914319"
,
Synopsis =
"..."
,
Title =
"Knockout.js: Building Dynamic Client-Side Web Applications"
},
new
Book {
Author = author,
Description =
"..."
,
ImageUrl =
"http://ecx.images-amazon.com/images/I/51AkFkNeUxL._AA160_.jpg"
,
Isbn =
"1449319548"
,
Synopsis =
"..."
,
Title =
"20 Recipes for Programming PhoneGap: Cross-Platform Mobile Development for Android and iPhone"
},
new
Book {
Author = author,
Description =
"..."
,
ImageUrl =
"http://ecx.images-amazon.com/images/I/51LpqnDq8-L._AA160_.jpg"
,
Isbn =
"1449309860"
,
Synopsis =
"..."
,
Title =
"20 Recipes for Programming MVC 3: Faster, Smarter Web Development"
},
new
Book {
Author = author,
Description =
"..."
,
ImageUrl =
"http://ecx.images-amazon.com/images/I/41JC54HEroL._AA160_.jpg"
,
Isbn =
"1460954394"
,
Synopsis =
"..."
,
Title =
"Rapid Application Development With CakePHP"
}
};
books.ForEach(b => context.Books.Add(b));
context.SaveChanges();
}
}
}
and the index.html under Author folder is
@model IEnumerable<BootstrapIntroduction.Models.Author>
@{
ViewBag.Title =
"Authors"
;
}
<h2>Authors</h2>
<p>
@Html.ActionLink(
"Create New"
,
"Create"
)
</p>
<table
class
=
"table table-bordered table-striped"
>
<thead>
<tr>
<th>@Html.DisplayNameFor(model => model.FirstName) </th>
<th>@Html.DisplayNameFor(model => model.LastName) </th>
<th>@Html.DisplayNameFor(model => model.Biography) </th>
<th>Actions</th>
</tr>
</thead>
<tbody data-bind=
"foreach: authors"
>
<tr>
<td data-bind=
"text: FirstName"
></td>
<td data-bind=
"text: LastName"
></td>
<td>
<a data-bind=
"attr: {href: '@Url.Action("
Details
")/' + Id }"
class
=
"btn btn-info"
>Details</a>
<a data-bind=
"attr: {href: '@Url.Action("
Edit
")/' + Id }"
class
=
"btn btn-primary"
>Edit</a>
<a data-bind=
"attr: {href: '@Url.Action("
Delete
")/' + Id }"
class
=
"btn btn-danger"
>Delete</a>
</td>
</tr>
</table>
@section Scripts {
<script type=
'text/javascript'
src=
'/Scripts/knockout-3.3.0.js'
></script>
<script>
function ViewModel(authors) {
var self =
this
;
self.authors = authors;
};
var viewModel =
new
ViewModel(@Html.HtmlConvertToJson(Model)));
ko.applyBindings(viewModel);
</script>
}
Thank you for your patient and I truly appreciate your helping to a beginner like me.
