### Modifying the `DefaultGenesis` | ||
|
||
It is possible to modify the DefaultGenesis parameters for modules by wrapping the module, providing it to the `*module.Manager` and injecting it with `depinject`. | ||
|
||
Example ( staking ) : | ||
|
||
```go | ||
type CustomStakingModule struct { | ||
staking.AppModule | ||
cdc codec.Codec | ||
} | ||
|
||
// DefaultGenesis will override the Staking module DefaultGenesis AppModuleBasic method. | ||
func (cm CustomStakingModule) DefaultGenesis() json.RawMessage { | ||
params := stakingtypes.DefaultParams() | ||
params.BondDenom = "mydenom" | ||
|
||
return cm.cdc.MustMarshalJSON(&stakingtypes.GenesisState{ | ||
Params: params, | ||
}) | ||
} | ||
|
||
// option 1 ( for depinject users ): override previous module manager | ||
depinject.Inject( | ||
// ... provider/invoker/supplier | ||
&moduleManager, | ||
) | ||
|
||
oldStakingModule,_ := moduleManager.Modules()[stakingtypes.ModuleName].(staking.AppModule) | ||
moduleManager.Modules()[stakingtypes.ModuleName] = CustomStakingModule{ | ||
AppModule: oldStakingModule, | ||
cdc: appCodec, | ||
} | ||
|
||
// option 2 ( for non depinject users ): use new module manager | ||
moduleManager := module.NewManagerFromMap(map[string]appmodule.AppModule{ | ||
stakingtypes.ModuleName: CustomStakingModule{cdc: appCodec, AppModule: staking.NewAppModule(...)}, | ||
// other modules ... | ||
}) | ||
|
||
// set the module manager | ||
app.ModuleManager = moduleManager | ||
``` |
