Create initial age

and welcome to gonna wash pants web development now we are going to be doing one of our first lessons in dotnet MVC as can be seen here we talked about initial concepts of what MVC stunning slow and daring large later on so first of all a what is MVC okay NBC is an architecture design patent that has been around for decades for a very long time Microsoft about 10 years ago decided to use it in its web development area it took over from web forms at the new center to create web apps with you can still crack web from believe me there's not many companies investing time anymore so NBC some time now good five years possibly seven has become a standard for cracking web apps but that is also just briefly I mentioned there is a new design and coming up roughly now as well so technology always moves MVC stands for a Model View controller part of its key aim is to break an applications code areas into into individual areas the model is meant to just hold a representation of data your trunks show the view mainly holds all the HTML or information you are showing the controller does all the heavy lifting it does all the work as an example you'd normally do all your validation your database calls and there you you're number crunching etc etc that the controller does all the heavy lifting so I guess it some start an app that would always be the thing now I'm going to be using Microsoft Visual Studio here and leave a community edition for 2013 so let's go file new project as you can see it's coming up make sure so look in all this environments it's easier to have things set wrong make sure you clicking here or here on visuals to get to work I've got the epic 2012 which is already old and make sure you click on asp.net MVC for web application take note of the framework that I'm working with in 4.5 what are we up to now are these 4.6 so make note of that because different framework support different things in MVC so it's important things we can give our application the name it's a special folder project I'm going to put here under just a 10 we will come pull this employee data okay now with the next window that we see make sure you have an empty an MVC application because I just want to demonstrate some basic commonality with and receipts there's other things you can obviously click here the basic will come and Microsoft web settings but just for the first one I'm just going to keep it nice and simple we will add stuff in so we can understand what's going on so make sure you click empty don't worry about unit tests make sure it's the razor and any time out we're going to come up let's just come up on the right we're going to discuss the folder structure just briefly so for those new to NBC I'm just want to give you a sense of understanding of what the folders mean overall from the application standpoint and you love it now yes it's good as you can see down here there are many pots that is added into an ABC application a number of lovelies guys doing some last-minute things and we should be good let's have a look over here okay let's open that up now as you can see we put this folder structure here I want to sort of explain some of the things some of the things as NBC I'm normal yelled web web forms as well app data is where you'd normally add to database app start is an interesting folder it holds files which will run in the application starts and I don't want to digress too much but this guy here is quite important NBC uses would quite click too many times I click in ok and we see there's a process called routing and this is done in our wraps and completes to get to TRL's just briefly mentioning that I will discuss more of that later on but feel free to have a look we're asking URLs it it tells NBC where to put the girls and how to use them graphics but I want to have maybe I will be trying to clear a tutorial on wrapping themself later on controllers so let's step back to what else open up NBC is made up of the closed models and views so we can see here so folders credit for each one and is you it has a sunroof completely rejected for this once there are not abused cloudy axes application there's no models controller reviews added to this application restage so to set up let's add a model and a mobile it's just purely a c-sharp class as a naming convention for Moses good to have the end of it cold model so things even identify the fire now I had credit some to help speed things up I have cousins I'm tired already so yes this should work fine listen here so feel free to pause and have a look at the code all recording a simple class here it's quite straightforward the name job title and age these are all properties which we'll be using it now application so you can see here this models folder like I was saying cause a representation of information that we want to display or use so that's what a model though now normally after we put a model in we can now add a controller and we want the controller to use that model so this is a good stage to build the application could you just say set up a part of the application can see the model father well that is happening or specularly I know that's cool we unearthed Nellie Bly back one off we go over whoops again this we will go over to here I've already created some code here so when we do create a controller in our moments everything will run a bit quicker so we have our build succeeded so now we add a controller a controller again is just it's not a c-sharp class I'm sorry to see sharp up but it's a special one so you go in your ad and controller a special part of it is what I'll just talk about a second we are creating it so you can create templates for your control is initially if you need to this is all quite a lot of taking but right now we're just going to train an empty MVC controller so I'm going to call some controller so add in here now what I mean by it is a special code sheet obviously it's just made up of c-sharp code I'll just address one important facet of it it inherits from this controller based class that's what makes it special this controller based class has many buttons to one of it is the mother of this action result and it holds many other properties which makes it controller file work controller is so we have to add in our employee data model so if you're new to C sharp we're just adding in this namespace here so we can get at this object here because we want to take this object to use it and show at the end view which we're going to so we copied over some code that you defined there let's just skip it I'll explain the code briefly this back end but first of all so here we have a first action and all pages come up with this index action you can see terms of strange setting called an action result and actually these views can return many different actual results as you call it we call Jason results and many other result spectively andis malicious the Griffis action result right there right now here and there he will create just a simple employee information class which we created here and then we're just going to simply add information for that so it can render to the screen this guy a ages one so he started worked really young just perfect work pipe really guess their knavery and he's a supervisor and he runs straight now this view will be we said that that's the mechanics that sends information back to our HTML or actually a name in NBC that you to the dot see HTML view and we're passing this temp employee object back now to add a view you right-click on this guy and you go here as view it's all flexible if you know where to click it's very safe so for our first one there's a number of things we can see we want razor in there there is another one but a razor it's ostensibly say so for my personal opinion just go replace your razor blades quite well again once you get might take a whirl but it's either standard and it works quite well but once you learn run it for a while so now here this model class what we're telling this view is to use this model class that we're going to put in here to show information it needs to know which model classically is and for us that's the employees information object so we click that now we and here in the scaffold template this allows us to render HTML quite quickly and easily you can do many different things create delete details empty empty really nothing for hours we just want the details we're just showing a 1b user and we just need to see these lead details on the end screen of one user partial view different subject use lay layer or master pages you can use master pages or layout pages some people who are new to that concept yeah what is clear master page and then you put you link this page that we're going to create into that master page but that's a different subject so with all that in mind we've got all ready to go we just click Add okay okay a little bit impatient arm so it voila it does everything for us so this is once you get your head round and we see it is quite useful for doing all these things made all this special code here is HTML our health is I'll talk more or less about those in later tutorials this one here we're just going to norris just sort of render a label not a text box nothing else because we can't edit it we just want to see it notice this piece of information here is important as we can see if you extend this page to use this model employee information to fill in information here against this label here and it does that by using the Lambada expression the model number up in the name and that's for the heading and then again we make one for the actual contents so this is our header and this is the actual contents so this is our header will be job title and this is the actual context so forth and social so that's it the natural it does come with predefined action links delete I will delete those because well technically don't work you have to put more code enough to make that magic happen so why has turnaround that doesn't work and it's open they use so now we should be able to go back to this cost bill succeeded coming up into crime slowly a choice oh okay start here we go now this will render straight to this index Musa Kusa the routing of NBC takes it can see that file it can use it and it can wrap straight there for other routing for other URLs that we're going to create we're going to have to complete librarian yeah that's NBC in writing is a bit of a different subject but some we will get to that as soon as NBC does and feel free to well what can I say fast-forward because I love my PC decently fastest open machines here we go oh yeah memory so rate and rate so we can see here afraid coming up job title these are supervisor and it's not one years old he's actually yes as we wanted really three years old so United yeah we can see how now but we can see everything quite well here now we've got physical code format application showing another page so so that's the aim of web technology so this could be deployed now and everybody be happy I will demonstrate just to there's many different ways of rendering information is obviously tons of different information that can be rendered I have already created so please to one here copy these guys over so I will dense well we must do them but at the same time so this guy here look we just talked about this one briefly we're just going to show a URL called time information look at the current dates and it doesn't change without the passive class back we can pass many different things about this special guide viewbag allows us to create dynamic stuff on the web page just string information if you want as well and we are going to do absolute the aim of this time information here is going to display the current date on that associated web page if we look at our next controller action here this is called the employee list what we're going to do here is again just use this employee object but show multiple people instead of just a one person so I wanted to showcase the use of NBC could be able to show multiple rather than just one so let's for each of these actual results we need to add a view and so we're not going to use a strongly typed line because we've got enough already shown any employee information on this one so everything should be set back as shown on the screen here all right now what we will do I don't now that's great as it is now so we will just press add and it'll get us that guy and so that's we well I really could practice but I do prefer my cue to us be working on simple trick so anyway so here's our view for that control action here and we're using a special rifle gear bag this guy if we live in over a little bit this guy here will grab this guy's context simple let's just so we'll leave them there let's just the fully get all the last we'll add a view to this guy as well so here on this one we will again do a different action here we will be using an employee information model class because we want to show employee information so that is open but this guy's this tandem change we want to show a list of employees like that like I mentioned so we want to select this one but I'm going to create we're going to show a list because here we can see we've got a list of employees so that should be set forth so the apfel set of this we click Add and by the power of obesity it's done again a lot of the hard work for us I want to draw attention to this important thing because I respect fire again programming in MVC you can get confused Bible it's important that this model is our I knew level if we can just show this and here if you look at this guy here you might notice this is just one object so it's not an ienumerable but this is showing multiples and that's what on your mobile does it's saying this holds a collection or a list of model information so that's an important just discrepancy between chain multiples and one until this guy got here the rest of it also obviously generated blame you see we will get rid of this closure because we will not be creating any button here now you can see that NBC is trying to make your life easier by already adding in all this code so if you want to go back to the crabapples all the useful suppose need to raise up what we're doing here so we're doing a loop let's say let's start the top this is kinda heads of our table and now let's get the bottom here this for each is going to display each employee in our class there so before each so that the guys of growth grads called information this like the start who when put in this guy and with obviously name job title and age in this level so let's spilled we have two year-olds two events which is timing for and employee list information there there are many more facets to MBC I've been writing to some time in software development and yeah it's in MVC complete web form me it's my personal opinion it is a difficult complicated than the old web form to work but hey technology moves on and we have to move with it so we're building here as mentioned this is going to go straight to our index page with that's the default of this application so we will see just one employee but I will let it finish it some compilations to movement here again I feel for your password it's going to be another few seconds so it is a bit better anytime now come on go in DC do your magic right here we go like I said it's defaulting into that index fear that we have so we gotta type in the physical URL we will do the time ah but so as we can see I'll bring over the toe here that's this view here wandering over oops let's get that time back so this is rendering this view here this URL and obviously it's calling this action result so we can see that it left one now let's do our employee list and they get this guy's of thusly calling our actions here actual results er Employee List which in gamma indirectly whatever lens one you call this view page here so one thing I briefly mentioned you might notice you know how does it know to go to the home directory will let me know me the controller here if it's called home it'll go to you type in home you don't change types of part of the control around it so this is called welcome controller you type in welcome here that you can change that in the code to point to whatever URL you want but generally that's how the URLs here work in the brief statement so okay so in this tutorial we just looked at the different parts and folders which may say NBC now we've talked about here that each NBC that normally has a control a model and views associated with two matches within that so that's the basic parts of and then we see a we've talked about here about the different ways that information is shown back it's a very flexible language and you can show many different parts within all of this but yeah so I hope this has been up to some people I will be creating other tutorials coming up soon and I just hope you have a pleasant stay and um thanks for viewing
