Submodules

appyter.profiles.default.fields.AutocompleteField module

class appyter.profiles.default.fields.AutocompleteField.AutocompleteField(constraint='.*', hint=None, **kwargs)[source]

Bases: Field

Representing a field that accepts a string with autocomplete. Auto complete will use choices or alternatively file_path – a url to load the choices as an array.

Be careful with this field, consider defining a constraint regex. Note that it is equivalent to

a string field, and still accepts choices not being autocompleted.

Parameters:

  • name – (str) A name that will be used to refer to the object as a variable and in the HTML form.

  • label – (str) A human readable label for the field for the HTML form

  • description – (Optional[str]) A long human readable description for the field for the HTML form

  • constraint – A regular expression for validating the file name.

  • hint – A hint to put in the field prior to content.

  • file_path – (Optional[str]) A remote url to download the autocomplete list. Should resolve to a json list of terms.

  • choices – (Union[List[str], Dict[str, str]]) A set of choices that are available for this field or lookup table mapping from choice label to resulting value

  • required – (Optional[bool]) Whether or not this field is required (defaults to false)

  • default – (str) A default value as an example and for use during prototyping

  • examples – (Optional[Union[List[str], Dict[str, str]]]) Named strings to provide as clickable examples

  • section – (Optional[str]) The name of a SectionField for which to nest this field under, defaults to a root SectionField

  • value – (INTERNAL Any) The raw value of the field (from the form for instance)

  • **kwargs – Additional keyword arguments used by other fields

constraint()[source]

Return true if the received args.value satisfies constraints. Should be overridden by subclasses.

appyter.profiles.default.fields.BoolField module

class appyter.profiles.default.fields.BoolField.BoolField(**kwargs)[source]

  • description – (Optional[str]) A long human readable description for the field for the HTML form

  • required – (Optional[bool]) Whether or not this field is required (defaults to false)

  • default – (bool) A default value as an example and for use during prototyping

  • section – (Optional[str]) The name of a SectionField for which to nest this field under, defaults to a root SectionField

  • yes_label – (Optional[str]) The text instead of “Yes”

  • no_label – (Optional[str]) The text instead of “No”

  • value – (INTERNAL Any) The raw value of the field (from the form for instance)

  • **kwargs – Additional keyword arguments used by other fields

Importantly, a FileField ultimately resolves to a URL supporting several schemes. Appyters ensure

that url is available as an actual file when the appyter executes.

  • section – (Optional[str]) The name of a SectionField for which to nest this field under, defaults to a root SectionField

  • value – (INTERNAL Any) The raw value of the field (from the form for instance)

  • **kwargs – Remaining arguments passed down to appyter.fields.Field’s constructor.

Bases: Field

Represing a variable number of instances of a given Field

constraint()[source]

Number of values should satisfy bounded constraints and all values should satisfy the field constraints.

prepare(req)[source]

Typically, you’ll just provide a list of values satisfying the Field type, for forms we support json pointer refs for compatibility with older form fields – these pointers are resolved during prepare. Basically:

{
  "variablefield": [{"$ref":"#/singlefield0"},{"$ref":"#/singlefield1"}],
  "singlefield0": "a",
  "singlefield1": "b"
}

Will resolve to

{"variablefield": ["a", "b"]}
Letting us construct the form as before but permitting us to reference form fields

generated on the fly that end up in the form request.

property raw_value

(UNSAFE) Raw value of the field

property value

(SEMI-SAFE) Effective raw value of the field when parsed and constraints are asserted. When instantiating code, you should use safe_value.
