How to change the output folder for migrations with asp.net Core?

Question

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.

Answer 1

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.

Answer 2

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
