Namespace LemonEdge.API.Attributes.Validation

Classes

DataSourceUniqueAttribute

Used only against the IDataSource object to validate that 3rd party data source keys are unique (if they are set as being unique in the IDataSourceType)

This should not be used against any other class for validation

DatabaseClassValidationAttribute

Allows you to create class level validation, instead of individual field level, that runs when directly connected to the database only

DatabasePropertyValidationAttribute

Allows you to write a formula against properties that are automatically evaluated to validate changes

This indicates the validation is only run if the code is executing directly connected to the database. If running through the web service this will not be executed. This is for performance on validations to only run db checks once from the service, and also because running async code synchronously can lock up UI - especially Xamarin UI

FileSafeNameValidationAttribute

Validates that the string property value conforms to a file safe name. See Utils.StringHelper.IsSafeFileName(string, bool)

GlobalUniqueEmailAttribute

Only used to validate user email property and ensures that it is unique across all accounts within the database, not just the current logged in account

MultipleUniqueAttribute

Enforces validation that the combination of specified property names must be unique for each instance of this object

PropertyValidationAttribute

Allows you to write a formula against properties that are automatically evaluated to validate changes

PropertyValidationByMethodAttribute

Attribute for validating objects/properties by targeting functions within classes the targeted function MUST ALWAYS RETURN A BOOLEAN

ReadOnlyAttribute

Indicates this property is read-only and can not be modified again by anything once it has been initially saved from new

For instance this is commonly used with auto-increment reference ids used in transactions

Requires the DBTrackChangesAttribute to be marked against this property as well

RequiredNoDefaultIDValidationAttribute

Indicates this is a required property and must have a value that is not the default value of that property type.

For instance if an integer it can not be 0, or if a Guid it can not be Guid.Empty

UniqueAttribute

Indicates this property must be unique across all instances of that type.

Commonly used on key properties, or names/codes that must be unique

If multiple properties need to be unique together you can use MultipleUniqueAttribute
