Retrieving Revisions from Revision History

  • 1.  Retrieving Revisions from Revision History

    Hi,

     

    I am trying to retrieve revisions on an user story. For some reason, it does not provide the revision data. Please see screenshots and code snippets below. 

     

    Ext.create('Rally.data.wsapi.artifact.Store', {
    models: ['UserStory'],
    autoLoad: true,
    limit: Infinity,
    context: {
    project: null
    },
    projectScopeUp: true,
    projectScopeDown: true,
    listeners: {
    scope: this,
    load: function (store, userstories, success) {
    console.log('_getUserStories');
    console.log(userstories);

    // Rally Revision History
    Ext.Array.each(userstories, function (story) {
    Ext.Array.each(story.get('RevisionHistory').Revisions, function (rev) {
    console.log('Revisions');
    console.log(rev);
    });
    });
    deffered.resolve([features, userstories]);
    }


    },
    filters: featurefilter,
    fetch: ['Project', 'ObjectID', 'Owner', 'Owner.Role', 'Role', 'RevisionHistory', 'Revisions', 'RevisionNumber', 'CreationDate', 'User']
    });

     

    Output:

    Vijay,

     

    I think you will need to call the Revisions Object via the ref that is provided.  I'm not a Javascript developer, but there is an example here that, will hopefully help:

     

    GitHub - nmusaelian-rally/revisions 

     

    Will also see if morky01 or corkr03 have any thoughts on this question.

    Hi Vijayakumar,

     

    Michael is correct and the example he provided you is good. Specifically, check out the app.js in that example, lines 25-38) and look into the implementation of each of these methods.

     

    artifacts.load().then({
    success: this._getRevHistoryModel,
    scope: this
    }).then({
    success: this._onRevHistoryModelCreated,
    scope: this
    }).then({
    success: this._onModelLoaded,
    scope: this
    }).then({
    success: this._stitchDataTogether,
    scope: this
    }).then({

     

    You shall see that the Revisions are not auto-included with the User Stories. You actually need to make a call to the RevisionHistory model and load/include/fetch the Revision information you need. See lines 66-67 in that app.js file:

     

    var revisions = history.get('Revisions');
    revisions.store = history.getCollection('Revisions',{fetch:['User','Description','CreationDate', 'RevisionNumber']});
