Type checkers for lesana fields.

Warning: this part of the code is still in flux and it may change significantly in a future release.

class lesana.types.LesanaBoolean(field, types, value_index=None)

Bases: lesana.types.LesanaType

A boolean value

empty()

load(data)

name = 'boolean'

name = 'datetime'

class lesana.types.LesanaDecimal(field, types, value_index=None)

Bases: lesana.types.LesanaType

A floating point number

empty()

load(data)

name = 'decimal'

class lesana.types.LesanaFile(field, types, value_index=None)

Bases: lesana.types.LesanaString

Relative paths are assumed to be relative to the base lesana directory (i.e. where .lesana lives)

name = 'file'

class lesana.types.LesanaFloat(field, types, value_index=None)

Bases: lesana.types.LesanaType

A floating point number

class lesana.types.LesanaInt(field, types, value_index=None)

If the field settings auto is increment return the value incremented by the value of the field setting increment (default 1).

empty()

load(data)

name = 'integer'

class lesana.types.LesanaList(field, types, value_index=None)

Bases: lesana.types.LesanaType

A list of other values

empty()

index(doc, indexer, value)

Index a value for this field type.

Override this for types that need any kind of special treatment to be indexed.

See LesanaList for an idea on how to do so.

load(data)

name = 'list'

class lesana.types.LesanaString(field, types, value_index=None)

Bases: lesana.types.LesanaType

A string of unicode text

empty()

load(data)

name = 'string'

class lesana.types.LesanaText(field, types, value_index=None)

Bases: lesana.types.LesanaString

A longer block of unicode text

name = 'text'

class lesana.types.LesanaTimestamp(field, types, value_index=None)

Bases: lesana.types.LesanaType

A unix timestamp, assumed to be UTC

empty()

load(data)

name = 'timestamp'

class lesana.types.LesanaType(field, types, value_index=None)

Bases: object

Base class for lesana field types.

auto(value)

Return an updated value, as appropriate for the field.

Default is to return the value itself, but types can use their configuration to e.g. increment a numerical value or return the current date(time).

empty()

index(doc, indexer, value)

Index a value for this field type.

Override this for types that need any kind of special treatment to be indexed.

See LesanaList for an idea on how to do so.

Bases: lesana.types.LesanaString
