## Backporting a fix

Developer is advised to clone the MinIO source and checkout the MinIO release tag customer is currently on.

```
λ git checkout RELEASE.2021-04-22T15-44-28Z
```

Create a branch and proceed to push the branch **upstream**

And now in the file `sql_app/main.py` let's integrate and use all the other parts we created before.

### Create the database tables

In a very simplistic way create the database tables:

```Python hl_lines="9-11"
{!../../../docs_src/sql_databases_peewee/sql_app/main.py!}
```

### Create a dependency

Create a dependency that will connect the database right at the beginning of a request and disconnect it at the end:

plugins {
    groovy
    idea // Need to apply the idea plugin, so the extended configuration is taken into account on sync
    id("gradlebuild.module-jar")
    id("gradlebuild.dependency-modules")
}

extensions.create<UnitTestAndCompileExtension>("gradlebuildJava", project, tasks)

removeTeamcityTempProperty()
addDependencies()
configureCompile()
configureSourcesVariant()
configureTests()

    return resetContainer(getSubjectGenerator().createTestSubject());
  }
