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

Bases: object

annotation_assoc = None

class of AnnotationAssociation (e.g. HistoryAnnotationAssociation)

annotation(item)

Return the annotation string made by the item’s owner or None if there is no annotation.

annotate(item, annotation, user=None, flush=True)

Create a new annotation on item or delete the existing if annotation is None.

class galaxy.managers.annotatable.AnnotatableSerializerMixin

Bases: object

add_serializers()

serialize_annotation(item, key, user=None, **context)

Get and serialize an item’s annotation.

class galaxy.managers.annotatable.AnnotatableDeserializerMixin

Bases: object

add_deserializers()

deserialize_annotation(item, key, val, user=None, **context)

Make sure val is a valid annotation and assign it, deleting any existing if val is None.

class galaxy.managers.annotatable.AnnotatableFilterMixin

Bases: object

filter_annotation_contains(item, val)

Test whether val is in the owner’s annotation.

galaxy.managers.api_keys module

class galaxy.managers.api_keys.ApiKeyManager(app)

Bases: object

__init__(app)

create_api_key(user)

get_or_create_api_key(user)

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.

galaxy.managers.base.parsed_filter

alias of galaxy.managers.base.ParsedFilter

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

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.

galaxy.managers.base.get_class(class_name)

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)

galaxy.managers.base.get_object(trans, id, class_name, check_ownership=False, check_accessible=False, deleted=None)

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)

Combine two lists into a single list.

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

class galaxy.managers.base.ModelManager(app)

model_class

alias of builtins.object

foreign_key_name = None

class galaxy.managers.base.HasAModelManager(app, manager=None, **kwargs)

Bases: object

Mixin used where serializers, deserializers, filter parsers, etc. need some functionality around the model they’re mainly concerned with and would perform that functionality with a manager.

model_manager_class = None

the class used to create this serializer’s generically accessible model_manager

__init__(app, manager=None, **kwargs)

manager

Return an appropriate manager if it exists, instantiate if not.

exception galaxy.managers.base.ModelSerializingError(err_msg=None, type='info', **extra_error_info)

Bases: galaxy.exceptions.InternalServerError

Thrown when request model values can’t be serialized

exception galaxy.managers.base.ModelDeserializingError(err_msg=None, type='info', **extra_error_info)

exception galaxy.managers.base.SkipAttribute

Bases: 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)

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

__init__(app, **kwargs)

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

add_serializers()

Register a map of attribute keys -> serializing functions that will serialize the attribute.

add_view(view_name, key_list, include_keys_from=None)

Add the list of serializable attributes key_list to the serializer’s view dictionary under the key view_name.

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

serialize(item, keys, **context)

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)

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.ModelDeserializer(app, validator=None, **kwargs)

Bases: galaxy.managers.base.HasAModelManager

An object that converts an incoming serialized dict into values that can be directly assigned to an item’s attributes and assigns them.

__init__(app, validator=None, **kwargs)

deserialize_bool(item, key, val, **context)

deserialize_int(item, key, val, min=None, max=None, **context)

deserialize_genome_build(item, key, val, **context)

Make sure val is a valid dbkey and assign it.

class galaxy.managers.base.ModelValidator(app, *args, **kwargs)

Bases: galaxy.managers.base.HasAModelManager

__init__(app, *args, **kwargs)

type(key, val, types)

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

Raises:exceptions.RequestParameterInvalidException – if not an instance.

basestring(key, val)

bool(key, val)

int(key, val)

nullable_basestring(key, val)

Must be a basestring or None.

int_range(key, val, min=None, max=None)

Must be a int between min and max.

basestring_list(key, val)

Must be a list of basestrings.

genome_build(key, val)

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)

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

subcontainer_model_class = None

parsed_filter

alias of ParsedFilter

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

string_standard_ops(key)

parse_bool(bool_string)

Parse a boolean from a string.

parse_id_list(id_list_string, sep=', ')

Split id_list_string at sep.

parse_int_list(int_list_string, sep=', ')

parse_date(date_string)

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).

__init__(app, *args, **kwargs)

static configure_provider(provider, credentials)

Given a provider name and required credentials, it configures and returns a cloudbridge connection to the provider.

Parameters:provider (string) – the name of cloud-based resource provided. A list of supported providers is given in

SUPPORTED_PROVIDERS variable.

Parameters:credentials (dict) – a dictionary containing all the credentials required to authenticated to the

specified provider.

Return type:provider specific, e.g., cloudbridge.cloud.providers.aws.provider.AWSCloudProvider for AWS. Returns:a cloudbridge connection to the specified provider.

get(trans, history_id, bucket_name, objects, authz_id, input_args=None)

Implements the logic of getting a file from a cloud-based storage (e.g., Amazon S3) and persisting it as a Galaxy dataset.

This manager does NOT require use credentials, instead, it uses a more secure method, which leverages CloudAuthz (https://github.com/galaxyproject/cloudauthz) and automatically requests temporary credentials to access the defined resources.

Parameters:

• trans (galaxy.webapps.base.webapp.GalaxyWebTransaction) – Galaxy web transaction
• history_id (string) – the (decoded) id of history to which the object should be received to.
• bucket_name (string) – the name of a bucket from which data should be fetched (e.g., a bucket name on AWS S3).
• objects (list of string) – the name of objects to be fetched.
• authz_id (int) – the ID of CloudAuthz to be used for authorizing access to the resource provider. You may get a list of the defined authorizations sending GET to /api/cloud/authz. Also, you can POST to /api/cloud/authz to define a new authorization.
• input_args (dict) – a [Optional] a dictionary of input parameters: dbkey, file_type, space_to_tab, to_posix_lines (see galaxy/webapps/galaxy/api/cloud.py)

Return type:

list of galaxy.model.Dataset

Returns:

a list of datasets created for the fetched files.

send(trans, history_id, bucket_name, authz_id, dataset_ids=None, overwrite_existing=False)

Implements the logic of sending dataset(s) from a given history to a given cloud-based storage (e.g., Amazon S3).

Parameters:

• trans (galaxy.webapps.base.webapp.GalaxyWebTransaction) – Galaxy web transaction
• history_id (string) – the (encoded) id of history from which the object should be sent.
• bucket_name (string) – the name of a bucket to which data should be sent (e.g., a bucket name on AWS S3).
• authz_id (int) – the ID of CloudAuthz to be used for authorizing access to the resource provider. You may get a list of the defined authorizations via /api/cloud/authz. Also, you can use /api/cloud/authz/create to define a new authorization.
• dataset_ids (set) – [Optional] The list of (decoded) dataset ID(s) belonging to the given history which should be sent to the given provider. If not provided, Galaxy sends all the datasets belonging to the given history.
• overwrite_existing (boolean) – [Optional] If set to “True”, and an object with same name of the dataset to be sent already exist in the bucket, Galaxy replaces the existing object with the dataset to be sent. If set to “False”, Galaxy appends datetime to the dataset name to prevent overwriting the existing object.

Return type:

tuple

Returns:

A tuple of two lists of labels of the objects that were successfully and unsuccessfully sent to cloud.

galaxy.managers.deletable module

Many models in Galaxy are not meant to be removed from the database but only marked as deleted. These models have the boolean attribute ‘deleted’.

Other models are deletable and also may be purged. Most often these are models have some backing/supporting resources that can be removed as well (e.g. Datasets have data files on a drive). Purging these models removes the supporting resources as well. These models also have the boolean attribute ‘purged’.

class galaxy.managers.deletable.DeletableManagerMixin

Bases: object

A mixin/interface for a model that is deletable (i.e. has a ‘deleted’ attr).

Many resources in Galaxy can be marked as deleted - meaning (in most cases) that they are no longer needed, should not be displayed, or may be actually removed by an admin/script.

delete(item, flush=True, **kwargs)

Mark as deleted and return.

galaxy.managers.markdown_parse module

Utilities for parsing “Galaxy Flavored Markdown”.

See markdown_util.py for loading objects and interacting with the rest of Galaxy. This file is meant to be relatively self contained and just used to “parse” and validate Galaxy Markdown. Keeping things isolated to allow re-use of these utilities in other projects (e.g. gxformat2).

galaxy.managers.markdown_parse.validate_galaxy_markdown(galaxy_markdown, internal=True)

Validate the supplied markdown and throw an ValueError with reason if invalid.

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.

galaxy.managers.markdown_util.ready_galaxy_markdown_for_import(trans, external_galaxy_markdown)

Convert from encoded IDs to decoded numeric IDs for storing in the DB.

galaxy.managers.markdown_util.ready_galaxy_markdown_for_export(trans, internal_galaxy_markdown)

Fill in details needed to render Galaxy flavored markdown.

Take it from a minimal internal version to an externally render-able version with more details populated and actual IDs replaced with encoded IDs to render external links. Return expanded markdown and extra data useful for rendering custom container tags.

galaxy.managers.markdown_util.internal_galaxy_markdown_to_pdf(trans, internal_galaxy_markdown, document_type)

galaxy.managers.markdown_util.resolve_invocation_markdown(trans, invocation, workflow_markdown)

Resolve invocation objects to convert markdown to ‘internal’ representation.

Replace references to abstract workflow parts with actual galaxy object IDs corresponding to the actual executed workflow. For instance:

convert output=name -to- history_dataset_id=<id> | history_dataset_collection_id=<id> convert input=name -to- history_dataset_id=<id> | history_dataset_collection_id=<id> convert step=name -to- job_id=<id>

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.

normalize_workflow_format(trans, as_dict)

Process incoming workflow descriptions for consumption by other methods.

Currently this mostly means converting format 2 workflows into standard Galaxy workflow JSON for consumption for the rest of this module. In the future we will want to be a lot more percise about this - preserve the original description along side the data model and apply updates in a way that largely preserves YAML structure so workflows can be extracted.

workflow_to_dict(trans, stored, style='export', version=None)

Export the workflow contents to a dictionary ready for JSON-ification and to be sent out via API for instance. There are three styles of export allowed ‘export’, ‘instance’, and ‘editor’. The Galaxy team will do its best to preserve the backward compatibility of the ‘export’ style - this is the export method meant to be portable across Galaxy instances and over time. The ‘editor’ style is subject to rapid and unannounced changes. The ‘instance’ export option describes the workflow in a context more tied to the current Galaxy instance and includes fields like ‘url’ and ‘url’ and actual unencoded step ids instead of ‘order_index’.

static get_step_map_over(current_step, steps)

Given a tool step and its input steps guess that maximum level of mapping over. All data outputs of a step need to be mapped over to this level.
