BuildUriList(ids, uri_format, uri_fields=("name","uri"))

source code

Builds a URI list as used by index resources.

Parameters:

ids - list of ids as strings
uri_format - format to be applied for URI
uri_fields - optional parameter for field IDs

MapFields(names, data)

source code

Maps two lists into one dictionary.

Example:

   >>> MapFields(["a", "b"], ["foo", 123])
   {'a': 'foo', 'b': 123}

Parameters:

names - field names (list of strings)
data - field data (list)

MapBulkFields(itemslist, fields)

source code

Map value to field name in to one dictionary.

Parameters:

itemslist - a list of items values
fields - a list of items names

Returns:

a list of mapped dictionaries

FillOpcode(opcls, body, static, rename=None)

source code

Fills an opcode with body parameters.

Parameter types are checked.

Parameters:

opcls (opcodes.OpCode) - Opcode class
body (dict) - Body parameters as received from client
static (dict) - Static parameters which can't be modified by client
rename (dict) - Renamed parameters, key as old name, value as new name

Returns:

Opcode object

FeedbackFn(msg)

source code

Feedback logging function for jobs.

We don't have a stdout for printing log messages, so log them to the http log at least.

Parameters:

msg - the message

CheckType(value, exptype, descr)

source code

Abort request if value type doesn't match expected type.

Parameters:

value - Value
exptype (type) - Expected type
descr (string) - Description of value

Returns:

Value (allows inline usage)

CheckParameter(data, name, default=_DEFAULT, exptype=_DEFAULT)

source code

Check and return the value for a given parameter.

If no default value was given and the parameter doesn't exist in the input data, an error is raise.

Parameters:

data (dict) - Dictionary containing input data
name (string) - Parameter name
default - Default value (can be None)
exptype - Expected type (can be None)

GetHandlerAccess(handler, method)

source code

Returns the access rights for a method on a handler.

Parameters:

handler (ResourceBase)
method (string)

Returns: string or None
