Save Dropdown List Document on Ubuntu For Free

welcome again to this asp.net core M missile tutorial by now in this tutorial we have covered several things about rock town but the entire data that we were using into a drop down that was hard code now today in this video we will learn how to get and save the data or drove down to a database okay that's a start so we will get the data or drove down from the database and basically for that we need to create a table into a database so we will learn how to add a new table into our F distinct database using code first approach then we will learn how to save the data of the stroke down to the database so we are going to perform two equations over here first one is get the data second one is save the data so we are again back to our book store web application and as a first task we need to create a new entity into our code let's open this data folder and inside this data folder we need to create one new class so let's right click on this folder choose add and click on the class option let's do a language click on the add button ok let's add a few properties over here first first one is Heidi and this is going to be the primary key and the identity we can either use text or you can use name as well over here that's our one more property stating description perfect let's save all the changes now let's go back to our contacts class this contacts class is available over here inside this data folder and the name is bookstore context here you can notice that we have already added this books table in the same manner if we need to add our second table that is language that's that table as well so here we need to use D be set inside the DB set we need to provide the type of our table that is language now we need to give it a name so we can simply choose language over here ok so we have created a new table and we have added the reference of that table into our context class now we need to appear to the relationship in between these two tables so let's open the books class and insert this books class right now you can see first thing would be that we need to convert it to the integer because in this table we are going to store the ID of our language so how can we do that we need to simply use integer over here and we need to update all the references as well we need to upgrade the same property into our books model as well so let us open the models inside the book model you can notice that this is the language property and in this language we need to convert it to the integer perfect yes Billy the solution because the bill is filled cannot implicitly convert let's see what all we got over here the error is coming from this dummy data source and since we are working with the live data base now then there is no need of using this hard code data so I can simply remove this one okay so we do not have a search functionality right now I can simply return null and we will implement it later I just simply want to remove this data that is hard-coded and let's remove it...
