I’m grabbing the ToTable name that was specified by ApplicationDbContext and then re-applying the name as lower case. I’ve added the foreach clause to lower case the name after the base class (IdentityDbContext) has already changed the names. Here’s my DbContext class that handles Identity in my ASP.NET Core app. It’s easy enough to do if you know the right path through the APIs. Since the IdentityDbContext class creates the table names in its OnModelCreating override, I needed to change those names to lower case after the fact. Select Person in the drop-down for Model class and FamilyTreeContext for Data context class. Select MVC Controller with views, using Entity Framework, and click Add. \ef functionname () But then when I save it, it saves as this. This will open the function using a default editor. How can I edit the function using PSQL The closest I've seen is \df+ functionname but the output is garbled and not editable. If you prefer not to have to do that and do want the identity tables etc to be all lower case, then you may still find my hack to be useful.įor a temporary workaround, I wanted to just change them to lower case so I could reap the benefits of vscode-database extension. In the Solution Explorer, right-click the Controllers folder, select Add and then Controller. 17 I created a default function in PGADMIN but the server doesn't have that software. I just fixed up the extension files manually for the time being. SQL (database) first means writing SQL scripts to create your database and creating your context and entity classes from your existing database. SQL (Database) First vs EF Core Migrations. Use the SQL method in MigrationBuilder to run any SQL statement. Although right now the installer hasn’t been updated with the new bits yet. To use Fluent API to override EF Core's default conventions. Update: The vscode-database maintainers have fixed the problem and you can now easily use the identity tables …just remember to put quotes around the camel-cased database objects when typing SQL. Shay Rojansky, who maintains the npgsql PostgreSQL providers for EF & EF Core, explained to me that if the tool simply placed quotes around the names, it would be okay. It’s anticipating lowercase and throwing exceptions when it hits the camelcased names. And it makes those names all camel-cased.ĭataGrip did not mind the camel cased identity table names but vscode-database didn’t comprehend the table names when it was reading the database to build Intellisense for the tooling. I’ve already been using the mssql extension to muck about with SQL Server data inside of VS Code:Īs I was using a default web app from the template, ASP.NET Identity was involved and the context to manage identity inherits from .IdentityDbContextĪnd IdentityDbContext has fluent API code to explicitly map table names which are not the same as the entity’s they are mapping. There are a bunch of database extensions in fact: But this time I wanted to play with the Visual Studio Code extension called “ vscode-database” which lets you interact with MySQL and PostgreSQL right in the IDE. Usually I use JetBrain’s DataGrip (database IDE) to check out the actual data. I was doing yet another exploration of EF Core in Visual Studio Code on my MacBook. " dependencies " : Īnd here is the screenshot of the data inserted to ElephantSQL Console.PostgreSQL doesn’t really like camel-case too much. To connect to postgresql server, you require “” nuget package, and for EF migrations you require “” package. So I am using a ASP.NET Core Web API project, I have created a API project with ASP.NET YO Generator. e FILE edit the query buffer (or file) with external editor. In this post I am using EF Migrations for creating databases. help on syntax of SQL commands, for all commands. You can register yourself and can create databases. SQL queries can return regular entity types or keyless entity types that are part of your model. SQL queries are useful if the query you want can't be expressed using LINQ, or if a LINQ query causes EF to generate inefficient SQL. They are offering a free tier postgresql database. Entity Framework Core allows you to drop down to SQL queries when working with a relational database. Since I don’t have an installed version available, I thought I will use postgresql as a service version from. Recently in ASP.NET Forums, someone asking about using postgresql with ASP.NET Core. PostgreSQL is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards-compliance. This post is about using PostgreSQL with ASP.NET Core.
