using MongoDB in microservice-service inside microservice solution which uses efcore #1269 | Support

Neozzz created 3 years ago

We created a microservice solution using the following command: abp new ZW -t microservice-pro -u angular

Then we added a microservice-service to the solution using: abp new CompanyService -t microservice-service-pro

Now I want to use MongoDB on the newly added µservice-service and keep using the ef core for the main solution for identity and other related features.

I've already tried to add mongodb into CompanyService µservice-service. I am getting issues with

Please let me know if this is possible, and if so is there any best practice?

Thank you

ABP Framework version: v4.3
UI type: Angular
DB provider: EF Core & MongoDB

hi Neozzz

You can completely disable transactions if your database doesn't support it.

we have a microservice-pro solution that uses efcore. i need to add a microservice service inside this solution. but this has to use mongo for storing its entities but at the same time has to make use of the efcore for saas, admin etc.

i have tried something, but while migrating we've to divide the concerns to both mongo and efcore. guess this is where am having the issue.

please lemme know how to proceed.

I have done the above changes as you suggested. But I am getting the following error. I'd request you to take a look at the code.

I added the following:

I had created a new class DatabaseMigrationEventHandlerBaseMongo for handling mongo db instead of DatabaseMigrationEventHandlerBase which uses ef core. It inherits from AbpMongoDbContext instead of AbpDbContext.

I think this is causing the issue.

If you could check the code that'd be great. Taking remote would be easier for you as the infra is running and debugging may be easier. Let me know.
