galaxy.managers package

Classes that manage resources (models, tools, etc.) by using the current Transaction.

Encapsulates the intersection of trans (or trans.sa_session), models, and Controllers.


  • model operations that involve the trans/sa_session (CRUD)
  • security: ownership, accessibility
  • common aspect-oriented operations via new mixins: sharable, annotatable, tagable, ratable

Not responsible for:

  • encoding/decoding ids
  • any http gobblygook
  • formatting of returned data (always python structures)
  • formatting of raised errors

The goal is to have Controllers only handle:

  • query-string/payload parsing and encoding/decoding ids
  • http
  • return formatting
  • control, improve namespacing in Controllers
  • DRY for Controller ops (define here - use in both UI/API Controllers)

In other words, ‘Business logic’ independent of web transactions/user context (trans) should be pushed into models - but logic that requires the context trans should be placed under this module.

galaxy.managers.base module

Keeps the older BaseController security and fetching methods and also defines a base ModelManager, ModelSerializer, and ModelDeserializer.

ModelManagers are used for operations on models that occur outside the scope of a single model object, such as:

  • object creation
  • object lookup
  • interactions between 2+ objects of different model classes

(Since these were to replace model Mixins from web/framework/base/ the rule of thumb used there also generally has been applied here: if it uses the trans or sa_session, put it in a manager and not the model.)

ModelSerializers allow flexible conversion of model objects to dictionaries. They control what keys are sent, how values are simplified, can remap keys, and allow both predefined and user controlled key sets.

ModelDeserializers control how a model validates and process an incoming attribute change to a model object.

galaxy.managers.base.security_check(trans, item, check_ownership=False, check_accessible=False)[source]

Security checks for an item: checks if (a) user owns item or (b) item is accessible to user. This is a generic method for dealing with objects uniformly from the older controller mixin code - however whenever possible the managers for a particular model should be used to perform security checks.


Returns the class object that a string denotes. Without this method, we’d have to do eval(<class_name>).

galaxy.managers.base.decode_id(app, id)[source]
galaxy.managers.base.get_object(trans, id, class_name, check_ownership=False, check_accessible=False, deleted=None)[source]

Convenience method to get a model object with the specified checks. This is a generic method for dealing with objects uniformly from the older controller mixin code - however whenever possible the managers for a particular model should be used to load objects.

galaxy.managers.base.munge_lists(listA, listB)[source]

Combine two lists into a single list.

(While allowing them to be None, non-lists, or lists.)

class galaxy.managers.base.ModelManager(app)[source]

Provides common queries and CRUD operations as a (hopefully) light layer over the ORM.


alias of object

foreign_key_name = None
query(eagerloads=True, **kwargs)[source]

exception galaxy.managers.base.SkipAttribute[source]

Bases: exceptions.Exception

Raise this inside a serializer to prevent the returned dictionary from having a the associated key or value for this attribute.

class galaxy.managers.base.ModelSerializer(app, **kwargs)[source]

Bases: galaxy.managers.base.HasAModelManager

Turns models into JSONable dicts.

Maintains a map of requestable keys and the Callable() serializer functions that should be called for those keys. E.g. { ‘x’ : lambda item, key: item.x, ... }

Note: if a key to serialize is not listed in the Serializer.serializable_keyset or serializers, it will not be returned.

To serialize call:
my_serializer = MySerializer( app ) ... keys_to_serialize = [ ‘id’, ‘name’, ‘attr1’, ‘attr2’, ... ] item_dict = MySerializer.serialize( my_item, keys_to_serialize )
static url_for(*args, **kargs)

‘service’ to use for getting urls - use class var to allow overriding when testing

If include_keys_from is a proper view name, extend key_list by the list in that view.

serialize(item, keys, **context)[source]

Serialize the model item to a dictionary.

Given model item and the list keys, create and return a dictionary built from each key in keys that also exists in serializers and values of calling the keyed/named serializers on item.

serialize_to_view(item, view=None, keys=None, default_view=None, **context)[source]

Use a predefined list of keys (the string view) and any additional keys listed in keys.

The combinations can be:
view only: return those keys listed in the named view keys only: return those keys listed no view or keys: use the default_view if any view and keys: combine both into one list of keys

__init__(app, *args, **kwargs)[source]
type(key, val, types)[source]

Check val against the type (or tuple of types) in types.

Raises:exceptions.RequestParameterInvalidException – if not an instance.

genome_build(key, val)[source]

Must be a valid base_string.

Note: no checking against installation’s ref list is done as many data sources consider this an open field.

class galaxy.managers.base.ModelFilterParser(app, **kwargs)[source]

Bases: galaxy.managers.base.HasAModelManager

Converts string tuples (partially converted query string params) of attr, op, val into either:

  • ORM based filters (filters that can be applied by the ORM at the SQL level) or
  • functional filters (filters that use derived values or values not within the SQL tables)

These filters can then be applied to queries.

This abstraction allows ‘smarter’ application of limit and offset at either the SQL level or the generator/list level based on the presence of functional filters. In other words, if no functional filters are present, limit and offset may be applied at the SQL level. If functional filters are present, limit and offset need to applied at the list level.

These might be safely be replaced in the future by creating SQLAlchemy hybrid properties or more thoroughly mapping derived values.

model_class = None

model class

__init__(app, **kwargs)[source]

Set up serializer map, any additional serializable keys, and views here.

date_string_re = None

regex for testing/dicing iso8601 date strings, with optional time and ms, but allowing only UTC timezone

Parse string 3-tuples (attr, op, val) into orm or functional filters.

parse_filter(attr, op, val)[source]

Attempt to parse filter as a custom/fn filter, then an orm filter, and if neither work - raise an error.

Raises:exceptions.RequestParameterInvalidException – if no functional or orm filter can be parsed.
UNDERSCORED_OPS = ('lt', 'le', 'eq', 'ne', 'ge', 'gt')

these are the easier/shorter string equivalents to the python operator fn names that need ‘__’ around them


Parse a boolean from a string.

parse_id_list(id_list_string, sep=', ')[source]

Split id_list_string at sep.

parse_int_list(int_list_string, sep=', ')[source]

Split int_list_string at sep and parse as ints.


Reformats a string containing either seconds from epoch or an iso8601 formated date string into a new date string usable within a filter query.

Seconds from epoch can be a floating point value as well (i.e containing ms).
