|
|
|
|
Override this method to configure the database \(and other options\) to be used for this context\.
|
|
This method is called for each instance of the context that is created\.
|
|
The base implementation does nothing\.
|
|
|
|
```csharp
|
|
protected override void OnConfiguring(Microsoft.EntityFrameworkCore.DbContextOptionsBuilder optionsBuilder);
|
|
```
|
|
#### Parameters
|

|
|
<a name='Pf2e.Database.Pf2eDbContext.OnConfiguring(Microsoft.EntityFrameworkCore.DbContextOptionsBuilder).optionsBuilder'></a>
|
|
|
|
`optionsBuilder` [Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContextOptionsBuilder 'Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder')
|
|
|

A builder used to create or modify options for this context\. Databases \(and other extensions\)
|

|
### Remarks
|
|
|
|
In situations where an instance of [Microsoft\.EntityFrameworkCore\.DbContextOptions](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContextOptions 'Microsoft\.EntityFrameworkCore\.DbContextOptions') may or may not have been passed
|
|
to the constructor, you can use [Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\.IsConfigured](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContextOptionsBuilder.IsConfigured 'Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\.IsConfigured') to determine if
|
|
the options have already been set, and skip some or all of the logic in
|
|
[Microsoft\.EntityFrameworkCore\.DbContext\.OnConfiguring\(Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\)](https://docs.microsoft.com/en-us/dotnet/api/Microsoft.EntityFrameworkCore.DbContext.OnConfiguring#Microsoft_EntityFrameworkCore_DbContext_OnConfiguring_Microsoft_EntityFrameworkCore_DbContextOptionsBuilder_ 'Microsoft\.EntityFrameworkCore\.DbContext\.OnConfiguring\(Microsoft\.EntityFrameworkCore\.DbContextOptionsBuilder\)').
