|
||||
it is a Part of xDashboard on SaherElm IT Center which provides:
|
||||
|
||||
- all requirements to Implement String Resource Features in a **xDashboard** based Project.
|
||||
|
||||
this module has following dependencies :
|
||||
|
||||
- xModels
|
||||
- xCommons
|
||||
- xDataService
|
||||
- xPushService
|
||||
- xIdentityModels
|
||||
- xIdentityService
|
||||
|
||||
for configure and use this Module refer to DI.XDIHelperExtension.cs file.
|
||||
|
||||
## String Resource
|
||||
|
||||
an string resource is a Key/Value based structure which used in Multi Language Applications for accessing Translated of Spcified Values by Key, in Specified Languages.
|
||||
this architecture is very useful for implementing other services in an Application. such as Terms and Conditions.
|
||||
|
||||
## Data Persists
|
||||
|
||||
all of Provided features of this Module is works based on Data Persistance. so data models is Very Important.
|
||||
in this section all Data models explained.
|
||||
|
||||
data manipulation done using **xDataService** provided Features.
|
||||
|
||||
- **XString**: an Entity Model for Mapping to Tables.
|
||||
- **XStringDto**: a Data Transfer Object for Representing a Data Model.
|
||||
- **XStringEntityConfiguration**: a Configuration file for XString Entity.
|
||||
- **XStringEntityHub**: a Hub Implementation for XString Entity Model.
|
||||
- **XStringDtoHub**: a Hub Implementation for XStringDto Model.
|
||||
- **XStringEntityRegisterar**: an Implementation class for Dynamically Register XString Entity in a DbContext.
|
||||
- **IXStringRepositoryEvents**: an Interface for Repository Events Describing of XString Entity.
|
||||
- **XStringRepositoryEvents**: an Implementation for Repository Events of XString Entity.
|
||||
- **IXStringKeyGenerator**: an Interface for Describing Key Generator Actions for XString Entity.
|
||||
- **XStringKeyGenerator**: an Implementation for Describing Key Generator Actions for XString Entity.
|
||||
- **IXStringRepository**: an Interface for Describing XString Repository Actions.
|
||||
- **XStringEFRepository**: an Implementation of EF Core based XString Repository Actions.
|
||||
- **XStringMongoRepository**: an Implementation of MongoDb based XString Repository Actions.
|
||||
- **XStringMongoRepository**: an Implementation of MongoDb based XString Repository Actions.
|
||||
- **XStringInMemoryRepository**: an Implementation of InMemory based XString Repository Actions.
|
||||
- **IXStringSeeder**: an Interface for Describe XString DbSeeder actions.
|
||||
- **XStringSeederBase**: an abstraction of Implementation of XString DbSeeder actions.
|
||||
- **IXStringRepositoryProvider**: an Interface for Describing XString Repository Provider (using Hubs) actions.
|
||||
- **XStringRepositoryProvider**: an Implementation of XString Repository Provider (using Hubs) actions.
|
||||
- **IXStringRepositoryService**: an Interface for Describing XString Repository Service Actions (using XStringDto).
|
||||
- **XStringRepositoryService**: an Implementation of XString Repository Service Actions (using XStringDto).
|
||||
- **IXStringServiceProvider**: an Interface for Describing XString Repository Service Actions Provider (using Hubs and XStringDto).
|
||||
- **XStringServiceProvider**: an Implementation of XString Repository Service Actions Provider (using Hubs and XStringDto).
|
||||
- **XStringGraphType**: introduce XString Data model for GraphQL using.
|
||||
- **XStringGraphQuery**: introduce Repositry Implementation of XString model actions as Query Actions for GraphQL using.
|
||||
- **XStringGraphSchema**: introduce XString Query Schema for GraphQL using.
|
||||
- **IXStringGraphQLTypeHelper**: an Interface for Describing XString GraphQL Type Helper Provided Actions.
|
||||
- **IXStringGraphQLTypeHelper**: an Implementation of XString GraphQL Type Helper Provided Actions.
|
||||
|
||||
data presistance almost is a Down Layer works which handled using Service it self.
|
||||
but in some Used cases of Applications Business Logics, for Manipulating resources you can use above Registered Services by Injecting them.
|
||||
|
||||
## Providers
|
||||
|
||||
this module actually used to act as a base Provider for implementing Features based on it.
|
||||
for this purpose, provides some Features which described in this section.
|
||||
|
||||
### String Resource Provider
|
||||
|
||||
some services used XString model for Provide Specially Concept's of Actions. for example Terms and Conditions Services use XString Persisted Resource for Specified Purpose.
|
||||
|
||||
this Module provides some sort of tools for this purpose. which described in this section.
|
||||
|
||||
#### Data Transfer Models
|
||||
|
||||
this service used some Data Transfer Models for Data Providing. which Described in this section.
|
||||
|
||||
```C#
|
||||
public class XLocaleResourceDto : XBaseDto
|
||||
{
|
||||
public string Language { get; set; }
|
||||
public string Value { get; set; }
|
||||
}
|
||||
|
||||
public class XResourceDto : XBaseDto
|
||||
{
|
||||
public string Resource { get; set; }
|
||||
public IEnumerable<XLocaleResourceDto> Locales { get; set; } = new HashSet<XLocaleResourceDto>();
|
||||
}
|

```
|
