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.
Responsibilities:
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.
Submodules¶
galaxy.managers.annotatable module¶
Mixins for Annotatable model managers and serializers.
- class galaxy.managers.annotatable.AnnotatableManagerMixin[source]¶
Bases:
object
- class galaxy.managers.annotatable.AnnotatableSerializerMixin[source]¶

- delete_api_key(user: IsUserModel) None [source]¶
Marks the current user API key as deleted.
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/controller.py 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.
- class galaxy.managers.base.ParsedFilter(filter_type, filter, case_insensitive)[source]¶
Bases:

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 )
- __init__(app: MinimalManagerApp, **kwargs)[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.
- skip(msg='skipped')[source]¶
To be called from inside a serializer to skip it.
Handy for config checks, information hiding, etc.
- 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
- class galaxy.managers.base.ModelValidator[source]¶

Convert an incoming serialized dict into values that can be directly assigned to an item’s attributes and assign them
- class galaxy.managers.base.ModelFilterParser(app: MinimalManagerApp, **kwargs)[source]¶
Bases:
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.

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_date(date_string)[source]¶

galaxy.managers.context module¶
Interfaces/mixins for transaction-like objects.
These objects describe the context around a unit of work. This unit of work is very broad and can be anything from the response to a web request, the scheduling of a workflow, the reloading the toolbox, etc.. Traditionally, Galaxy has simply passed around a GalaxyWebTransaction object through all layers and large components of the Galaxy app. Having random backend components define explicit dependencies on this however is inappropriate because Galaxy may not be used in all sort of non-web contexts. The future use of message queues and web sockets as well as the decomposition of the backend into packages only further make this heavy reliance on GalaxyWebTransaction inappropriate.
A better approach is for components to annotate their reliance on much narrower, typed views of the GalaxyWebTransaction. This allows explicit declaration of what is being required in the context of a method or class and allows the Python type system to ensure the transaction supplied to the method is appropriate for the context. For instance, an effective use of the type system in this way can prevent the backend work context used to schedule workflow from being supplied to a method that requires an older-style WSGI web response object.
There are various levels of transactions defined in this file - these
include galaxy.managers.context.ProvidesAppContext
,
galaxy.managers.context.ProvidesUserContext
,
and galaxy.managers.context.ProvidesHistoryContext
. Methods
should annotate their dependency on the narrowest context they require.
A method that requires a user but not a history should declare its
trans
argument as requiring type galaxy.managers.context.ProvidesUserContext
.

galaxy.managers.markdown_parse module¶
Utilities for parsing “Galaxy Flavored Markdown”.

galaxy.managers.markdown_util module¶
Utilities defining “Galaxy Flavored Markdown”.
This is an extension of markdown designed to allow rendering Galaxy object references.
The core “Galaxy Flavored Markdown” format should just reference objects by encoded IDs - but preprocessing should allow for instance workflow objects to be referenced relative to the workflow (inputs, outputs, steps, etc..) and potential history flavor would allow objects to be referenced by HID. This second idea is unimplemented, it is just an example of the general concept of context specific processing.

Convert from encoded IDs to decoded numeric IDs for storing in the DB.
- galaxy.managers.markdown_util.resolve_invocation_markdown(trans, invocation, workflow_markdown)[source]¶

Also expand/convert workflow invocation specific container sections into actual Galaxy markdown - these containers include: invocation_inputs, invocation_outputs, invocation_workflow. Hopefully this list will be expanded to include invocation_qc.
