Lesson 3 - E-shop in ASP.NET Core MVC - Products and categories
In the previous lesson, E-shop in ASP.NET Core MVC - Identity, database, and layout, except for other things, we looked at controlling how the database is generated using migrations. In today's ASP.NET Core tutorial, we're going to extend our data model and add two basic entities - Products and Categories.
Products
Those are, of course, the basis of every e-shop. Our product will consist of the following attributes:
ProductId(int) - The product ID, primary key, autoincrementCode(nvarchar 255) - Barcode for the merchant (e.g. EAN or anything else)Url(nvarchar 255) - URL address of the product (e.g.green-flowerpot-ella) for better SEO optimizationTitle(nvarchar 255) - Product titleShortDescription(nvarchar 255) - A short description that will go to the HTML meta tagDescription(text) - A longer description for the product detail page, may contain HTML markupPrice(decimal(10,1)) - Product priceOldPrice(decimal(10,1)) - The old product price (if discounted)Stock(int) - The number of items in stockImagesCount(int) - The number of pictures of the productHidden(bit) - Indicates whether the product is hidden (1/0, see below).
The only column that isn't mandatory (can be null) is
OldPrice.
Data model
In the data project, add a new Product class to the
Models/ folder and make it public (as well as all
other data model classes). We'll add the class properties as listed above and
attach attributes which we'll explain in a moment:
