Documemt how do generate migrations for an Blazor WASM app #4230

Open tysongibby opened 1 year ago

tysongibby commented 1 year ago

Thank you for looking at this issue.

I have not yet been able to get this project to successfully create the first SQLite database migration. Link to the repo for my full code

Eric Sink on the SQLitePCL.raw project thought this may be an issue related to EfCore.

I am receiving the error "The specified deps.json [C:\git\ThePlayer\ThePlayer\Client\bin\Debug\net6.0\ThePlayer.Client.deps.json] does not exist" when I run the database migration command "add-migration initial"

I am using the following: SQLitePCLRaw version 2.1.3 nuget package: SQLitePCLRaw.bundle_e_sqlite3 Microsoft.EntityFrameworkCore.Sqlite.Core version 6.0.12

Visual Studio 2022 17.43, .NET 6 Blazor WASM, Windows 11 Pro 22H2 22621.963, Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz

Target framework:
.NET 6, Blazor WASM, client browser

These are the packages currently referenced in my project:

  <ItemGroup>    
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly" Version="6.0.12" />
    <PackageReference Include="Microsoft.AspNetCore.Components.WebAssembly.DevServer" Version="6.0.12" PrivateAssets="all" />

@bricelam This is a deps.json case which is fully reproducible on my machine and doesn't go away after a full clean and rebuild. Also, the build outside of dotnet ef works fine. Any ideas?

ErikEJ commented 1 year ago

I think this is failing because ThePlayer.Cleient is a wasm client project with no deps.json file and can not be executed by dotnet exec.

Maybe the SDK type could be detected and some actionable error message given, with a docs link.

tysongibby commented 1 year ago

@ErikEJ & @bricelam Thanks for looking at this. Is there a work-around I could be implementing or something different I can be doing for now?

tysongibby commented 1 year ago

@ErikEJ & @bricelam updated to 2.1.4, still having the same issue.

ajcvickers commented 1 year ago

@tysongibby The workaround is to create a separate console application project in the solution. This project is used only to enable the EF tools to create an appropriate context instance. The project needs to reference the project containing your DbContext and the EF Core database provider you are using. For example:

<Project Sdk="Microsoft.NET.Sdk">

    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net6.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.EntityFrameworkCore.Sqlite.Core" Version="6.0.12" />
        <PackageReference Include="SQLitePCLRaw.core" Version="2.1.3" />
        <PackageReference Include="SQLitePCLRaw.lib.e_sqlite3" Version="2.1.3" />
        <PackageReference Include="SQLitePCLRaw.provider.e_sqlite3" Version="2.1.3" />
    </ItemGroup>

    <ItemGroup>
      <ProjectReference Include="..\ThePlayer\Shared\ThePlayer.Shared.csproj" />
    </ItemGroup>

</Project>

The console application needs to have an IDesignTimeDbContextFactory. Something like this:

using Microsoft.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore.Design;
using ThePlayer.Shared.Data.Context;

Console.WriteLine("Hello, World!");

public class ContextFactory : IDesignTimeDbContextFactory<ThePlayerContext>
{
    public ThePlayerContext CreateDbContext(string[] args) 
        => new(null, new DbContextOptionsBuilder<ThePlayerContext>().UseSqlite(args[0]).Options);
}

This can then be used to generate migrations from the command line. For example:

PS C:\local\code\repros\ThePlayer-master\ThePlayer-master\ConsoleApp1> dotnet ef migrations add One --project ..\ThePlayer\Shared\ThePlayer.Shared.csproj -- "DataSource=ThePlayer.db"
Build started...
Build succeeded.
Done. To undo this action, use 'ef migrations remove'
PS C:\local\code\repros\ThePlayer-master\ThePlayer-master\ConsoleApp1>

@ajcvickers Docs enhancement?

tysongibby commented 1 year ago

Thanks, I'll implement that tonight after work.

@tysongibby In my example I set it up to take the connection string from the command line. Looks like you are not passing it. The connection string doesn't have to come from the command line, but then you shouldn't be trying to get it out of args.

@ajcvickers Thanks for your help and your patience. I am obviously doing something wrong implementing the work-around. I am getting an error where it can't find the dbcontext:
