How to change the output folder for migrations with asp.net Core?
asp.netDatabaseEntity Frameworkasp.net CoreCommand Line-Interfaceasp.net Problem Overview
Does anyone know how to change the output directory of the following command?
dotnet ef migrations add Initial --context EsportshubApi.Models.ApplicationDbContext
I tried to add the option:
--content-root-path 'Migrations/Identity'
But that doesn't do anything. There is a --data-dir
option as well and something else with directory. But none of them is the output for migrations.
My problem is that I have 2 DbContexts so I want their migrations to be separated.
asp.net Solutions
Solution 1 - asp.net
dotnet ef migrations add Initial --context EsportshubApi.Models.ApplicationDbContext -o YourFolderPath
dotnet ef migrations add
Adds a new migration.
Arguments:
Argument | Description |
---|---|
<NAME> |
The name of the migration. |
Options:
Option | Short | Description |
---|---|---|
--output-dir <PATH> |
-o |
The name of the migration. |
--namespace <NAMESPACE> |
-n |
The namespace to use for the generated classes. Defaults to generated from the output directory. Added in EF Core 5.0. |
Also here are the common options you can use with this command.
Solution 2 - asp.net
For Package Manager Console
run this command:
PM> Add-Migration 001 -OutputDir "Data/Migrations"
My structure is:
.AspCoreProject
-Data
-Migrations
20190721162938_001.cs
MainDbContextModelSnapshot.cs
Update:
For removing last migration use:
PM> Remove-Migration
Note: If the migration is already applied to the database, then you will get this error:
> The migration '20190721162938_001' has already been applied to the database. Revert it and try again. If the migration has been applied to other databases, consider reverting its changes using a new migration.
Then run:
PM> Remove-Migration -Force
If your migration is not the last migration. first, rollback to the migration you need by Update-Database
then delete all migration classes after that migration.
PM> Update-Database -Migration 001
This will revert all migrations after 001
Solution 3 - asp.net
In EF Core 5.0, you are free to move Migration files and changes their namespace manually. New migrations are created as siblings of the last migration. Alternatively, you can specify the directory at generation time as follows:
> .Net core CLI
dotnet ef migrations add InitialCreate --output-dir Your/Directory
> PowerShell
Add-Migration InitialCreate -OutputDir Your\Directory
Solution 4 - asp.net
You just need to use -o Or --output option with your command,
To do so, you need to explore to your root project folder, eg: C:\project\SampleAPi
and use this command
dotnet ef migrations add DbInitial --context SampleAPi.Infrastructure.DbContext -o Infrastructure/Migrations
and then
dotnet ef database update
