Here I want to consider the question how to define a TWX service which could create a Bom and Viewable Lists from json files. This will be very helpful option when we want to display some CreoView data in the thingview. How to extract BOM and viewable data form a Creo View /Illustrate *.pvz file is shown in the post "How to extract the components with properties from a pvz file".
In this example the json files are saved in a thingworx repository (means a thing form template FileRepostiroy) e.g. "CAD-Files-Repository" :
1.)Create a service for the BOM List /InfoTable
var params = { path: the_json_path /* STRING */ // path it set to the input argument // example for such setting value // --> "/json_lists/Machine-complete-CV.PVZ-bomlist.json" var Content = Things["CAD-Files-Repository"].LoadJSON(params); //This will call the method LoadJSON(params) of the thing CAD-File-Reposistory var params1 = { infoTableName: undefined /* STRING */, dataShapeName: "BomListStruct" /* DATASHAPENAME */ }; // result: INFOTABLE var jsonTable = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params1); var result = DataShapes.ThingviewBomData.CreateValues(); // working fine for(i in Content.array){ jsonTable.AddRow({Part:Content.array[i].part, Description:Content.array[i].description, sBOMDepth:Content.array[i].sBOMDepth, sBOMID:Content.array[i].sBOMID, sBOMIDPath:Content.array[i].sBOMIDPath, sBOMName:Content.array[i].sBOMName, sBOMPath:Content.array[i].sBOMPath, path:Content.array[i].sBOMIDPath, parentPath:Content.array[i].sBOMIDPath.substring(0,Content.array[i].sBOMIDPath.lastIndexOf('/')) }); } result = jsonTable;
The parentPath infoTable field is required for Tree Widget to display the BOM list as tree
The following code:
for(i in Content.array) { jsonTable.AddRow(Content.array[i]);}
the code above will transfer 1 to 1 all fields defined in the json file with data into infoTable fields. In this case is not used because we have different mapping for "parentPath" -> it is new in the output InfoTable and is not contained by the json file.
2.)Create a service for the BOM List /InfoTable (steps are similar to 1.)
var params = { //path: "/json_lists/Machine-complete-CV.PVZ-viewablelist.json" /* STRING */ path: the_json_path /* STRING */ }; var Content = Things["CAD-Files-Repository"].LoadJSON(params); var params1 = { infoTableName: undefined /* STRING */, dataShapeName: "viewablelist_new" /* DATASHAPENAME */ }; // result: INFOTABLE var jsonTable = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape(params1); var result = DataShapes.ThingviewBomData.CreateValues(); for(i in Content.array){ jsonTable.AddRow({name:Content.array[i].name, //type:Content.array[i].description, type:"viewable", value:Content.array[i].value, hasAnimation:Content.array[i].hasAnimation, hasSequence:Content.array[i].hasSequence }); } result = jsonTable;
