Hi Nate,   thanks for your reply. My solution will break down in such a case, indeed. So here is what I need/have:   I have a tool which allows the user to select a specific workflow and appropriate input data from his/her history. On execution a script is used to do several preprocessing steps and at last the selected workflow will be executed via the API functions (in batch mode if the user selected more than one input (pair). As far as I have seen from the documentation one needs to specifiy a history name or id which will hold the output data. Logically the output should be submitted to the users current history which serves as the input source. That?s why I need the id of the users current history.   Of course, workflows can be executed directly within Galaxy but we need to perform these preprocessing steps like copying files and, more important, we have paired end data which isn?t that good supported for batch processing yet.   Thanks for your help!   Cheers, Sascha   Original Message processed by CONSOLIDATE Subject: Re: [galaxy-dev] Some questions about histories Sent: Mittwoch, 15.

Hi again! I was able to implement a quite dirty solution:

first I edited /lib/galaxy/model/mapping.py and extended

assign_mapper( context, User, User.table, properties=dict( histories=relation( History, backref="user", order_by=desc(History.table.c.update_time) ), active_histories=relation( History, primaryjoin=( ( History.table.c.user_id == User.table.c.id ) & ( not_( History.table.c.deleted ) ) ), order_by=desc( History.table.c.update_time ) ), galaxy_sessions=relation( GalaxySession, order_by=desc( GalaxySession.table.c.update_time ) ), stored_workflow_menu_entries=relation( StoredWorkflowMenuEntry, backref="user", cascade="all, delete-orphan", collection_class=ordering_list( ’order_index’ ) ), _preferences=relation( UserPreference, backref="user", collection_class=attribute_mapped_collection(’name’)), # addresses=relation( UserAddress, # primaryjoin=( User.table.c.id == UserAddress.table.c.user_id ) ) values=relation( FormValues, primaryjoin=( User.table.c.form_values_id == FormValues.table.c.id ) ), api_keys=relation( APIKeys, backref="user", order_by=desc( APIKeys.table.c.create_time ) ), ) )

by this: currentHistory=relation( History, primaryjoin=( ( History.table.c.user_id == User.table.c.id ) & ( not_( History.table.c.deleted ) ) & (GalaxySession.table.c.current_history_id == History.table.c.id) ), order_by=desc( GalaxySession.table.c.update_time ) )

As far as I am correct, this selects all current histories of all sessions per user. These histories get sorted by the latest session change which should always lead to the current history as the first entry.

Inside my tool I use this to get the current history id and hash it to an id which can be used for API calls:

${__app__.security.encode_id( ’%s’ % $__app__.model.User.get($__user_id__).currentHistory[0].id )}

Until now everything seems to work as it should.

Hi Sascha, This will break down if you have a user with more than one active sessions (in two browsers, for example). The most recent session and its current history will always be used, rather than the one that the job was initiated from. Jobs are intentionally decoupled from histories since histories are not the only context in which a job can run. There may be accurate ways of getting to the parent history at the job context, but it?d help to know what you?re trying to do. Thanks, --nate

Finally I have another question about the histories and API. Referring to this thread: http://gmod.827538.n3.nabble.com/How-to-use-scripts-api-update-py-td3657803....

Are you working on this? Updating history items via the API would be really helpful for my usecase. If not, can you give me some hints where I can have a look at to enable it by my own?

No, nothing?s been written for this yet. Have a look at lib/galaxy/web/api/history_contents.py, and you may find the update() method in other API controllers to be a useful template. One that is fairly well sorted is the quota API (quotas.py). --nate

Thanks a lot!

Cheers, Sascha

I have two questions about histories in Galaxy:

1. Is it possible to mark/set a history as published via the API? 2. How can I get the ID of the current users history via a tool? Something like ${__app__.model.User.get($__user_id__).histories[0].id} ?!

Thanks in advance!
