Initializes a new instance of the FormModel class

Invoked to allow the row to hydrate its fields/state from AmorphousData bag. For example, this may be used to reconstruct some temporary object state that is not stored as a part of established business schema. The operation is performed per particular targetName (name of physical backend). Simply put, this method allows business code to "specify what to do after object gets loaded from THE PARTICULAR TARGET backend store". An example: suppose current MongoDB collection stores 3 fields for name, and we want to collapse First/Last/Middle name fields into one field. If we change rowschema then it will only contain 1 field which is not present in the database, however those 'older' fields will get populated into AmorphousData giving us an option to merge older 3 fields into 1 within AfterLoad() implementation

Writes default values specified in schema into fields. Pass overwrite=true to force defaults over non-null existing values (false by default)

Invoked to allow the row to transform its state into AmorphousData bag. For example, this may be usefull to store extra data that is not a part of established business schema. The operation is performed per particular targetName (name of physical backend). Simply put, this method allows business code to "specify what to do before object gets saved in THE PARTICULAR TARGET backend store"

In base class applies Config attribute. Useful for typed rows

Converts field value to the type specified by Schema.FieldDef. For example converts GDID->ulong or ulong->GDID. This method can be overridden to perform custom handling of types, for example one can assign bool field as "Si" that would convert to TRUE. This method is called by SetFieldValue(...) before assigning actual field buffer

Copies fields from this row into another row/form. Note: this is shallow copy, as field values for complex types are just copied over

Override to save model into data store. Return "predictable" exception (such as key violation) as a value instead of throwing. Throw only in "un-predictable" cases (such as DB connection is down, not enough space etc...). Return extra result obtained during save i.e. a db-assigned auto-inc field

Object override - sealed. Override Equals(row) instead

Override to perform custom row equality comparison. Default implementation equates rows using their key fields

Override to filter-out some fields from serialization to JSON, or change field values. Return name null to indicate that field should be filtered-out(excluded from serialization to JSON)

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Override to perform dynamic substitute of field def for the specified field. This method is used by client ui/scaffolding to extract dynamic definition for a field (i.e. field description, requirement, value list etc.) as dictated by business logic. This method IS NOT used by row validation, only by client that feeds from row's metadata. The default implementation returns the original field def, you can return a substituted field def per particular business logic

Override to perform dynamic substitute of field value for the specified field. This method is used by client ui/scaffolding to extract field values for a field as dictated by business logic. This method IS NOT used by row validation, only by client that feeds from row's metadata. The default implementation returns the original GetFieldValue(fdef), you can return a substituted field value per particular business logic

Override to perform dynamic lookup of field value list for the specified field. This method is used by client ui/scaffolding to extract dynamic lookup values as dictated by business logic. This method IS NOT used by row validation, only by client that feeds from row's metadata. This is a simplified version of GetClientFieldDef

Returns values for fields that represent row's primary key

Returns field value as string formatted per target DisplayFormat attribute

Returns field value as string formatted per target DisplayFormat attribute

For fields with ValueList returns value's description per specified targeted schema

For fields with ValueList returns value's description per specified targeted schema

Object override - gets hash code from key fields

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

The base class does not implement this method. Override to persist row fields into config node

Saves form into data store. The form is validated first and validation error is returned which indicates that save did not succeed due to validation error/s. The core implementation is in DoSave() that can also abort by either returning execption when predictable failure happens on save (i.e. key violation). Other exceptions are thrown. Returns extra result obtained during save i.e. a db-assigned auto-inc field

If non null or empty parses JSON content and sets the RoundtripBag

Returns true if this row satisfies simple filter - it contains the supplied filter string. The filter pattern may start or end with "*" char that denotes a wildcard. A wildcard is permitted on both sides of the filter value

Returns a string that represents the current object.

Performs validation of data in the row returning exception object that provides description in cases when validation does not pass. Validation is performed not targeting any particular backend

Validates row using row schema and supplied field definitions. Override to perform custom validations, i.e. TypeRows may directly access properties and write some validation type-safe code The method is not expected to throw exception in case of failed validation, rather return exception instance because throwing exception really hampers validation performance when many rows need to be validated

Validates row field using Schema.FieldDef settings. This method is invoked by base Validate() implementation. The method is not expected to throw exception in case of failed validation, rather return exception instance because throwing exception really hampers validation performance when many rows need to be validated

Validates row field by name. Shortcut to ValidateField(Schema.FieldDef)

Writes row as JSON either as an array or map depending on JSONWritingOptions.RowsAsMap setting. Do not call this method directly, instead call rowset.ToJSON() or use JSONWriter class

Try to convert .NET native object type to corresponding Erlang term. Throw exception if conversion is not possible

Try to convert .NET native object type to corresponding Erlang term of given type. Throw exception if conversion is not possible

Convert Row to a hierarchical term that corresponds to the row's schema. The Erlang term is in the form:

Serializes object into JSON string

Serializes object into JSON format using provided TextWriter

Serializes object into JSON format using provided stream and optional encoding

Convert an Erlang hierarchical term representing a schema to a Row.

Gets/sets CSRF token

Gets/sets form mode - unspecified|insert|edit. This field may be queried by validate and save, i.e. Validate may perform extra cross checks on Insert - i.e. check whether some other user is already registered with the specified email in this form etc.

Returns data that does not comply with known schema (dynamic data). The field names are NOT case-sensitive

False by default for forms, safer for web. For example, no injection of un-inteded fields can be done via web form post

Returns the name of data store target obtained from App.DataStore by default. Override to supply a different name. This property is used for validation

True if RoundtripBag is allocated

Gets/sets field values by positional index(Order)

Gets/sets field values by name

Returns lazily-allocated RoundtripBag. Use HasRoundtripBag to see if it is allocated not to allocate on get

References a schema for a table that this row is a part of
