Hi web2py, I am a fairly experienced coder, but am new to web-programming and web2py. Ihave read the documentation, bought the book, and done quite a few of the examples which have run OK. I am coding on Windows7 OS - using Firefox browser.
I am trying to modularise my current demo web2py web-app, so that when i click on a webGrid (a 'view' link) on the right-hand-side of page, my column on the left-hand-side of the page updates to show the details of the selected patient/scan row. Before trying this, I have got it to work so the whole page updates when I click on that link, but to progress this further, I want only the left-hand column to update. I am trying to adapt the example from the book (Chapter 2 - Designing Modular Applications) and the example from the 'Components' section of the online docs (http://web2py.com/books/default/chapter/29/12). Currently, the initial index page loads OK, with the left hand column showing the default (scanId=1) record. It's the click on 'view' which doesn't work. I am trying 2 options and they both give me a blank 'none' page, when I click on the 'view' link. I can't figure out the mistake I am making and have been working on it for over a day now. The code is below. As you can see, I think its because I am still unclear on how the load and 'response.ajax = 'web2py_component(' calls work. Hope you can help. angle ****************************** ******* DEFAULT.PY ******** ****************************** def index(): import webgrid from gluon.tools import Crud crud = Crud(icc_db) grid=webgrid.WebGrid(crud) grid.datasource = icc_db(icc_db.scan.id>0) grid.pagesize = 20 grid.action_links = ['view'] grid.action_headers = ['view'] grid.enabled_rows = ['header','pager','footer'] grid.crud_function = 'view' #if request.controller == 'default' and request.function == 'index': # if request.args: # crud.settings[request.args(0)+'_next'] = URL('index') return dict(grid=grid()) def view(): vars1={'scanId':(request.args[2])} ##### THIS IS WHERE I AM TRYING VARIOUS OPTIONS - RETURN 'NONE' page #### LOAD('default','post.load',ajax=True,target='patient',vars={'scanId':( request.args[2] or 1)}) #response.ajax = \ 'web2py_component("%s","patient",ajax=True,vars=vars1)' % URL ('patient') #response.ajax = 'web2py_component("post.load",ajax=True,target="patient",vars={"scanId":( request.args[2] or 1)})' % URL ('patient') def post(): #This works OK... patientId = (icc_db(icc_db.scan.id == request.vars.scanId).select(icc_db.scan.patient_fk)[0].patient_fk or -1) ... return dict(patientScanRecs = patientScanRecs, scanImageRecs = scanImageRecs) ... ************************************************************************ * Views/Layout.html (webGrid + the left column) * ************************************************************************ <div id="displayBox_centre"> {{=grid}} </div> <div id="displayBox_left"> {{ if request.args: }} {{ =LOAD('default','post.load',ajax=True,target='patient',vars= {'scanId':(request.args[2] or 1)}) }} {{ else: }} {{ =LOAD('default','post.load',ajax=True,target='patient', vars={'scanId':1}) }} {{pass}} </div> ************************************ ****** Views/default/post.load ****** ************************************ <H2> Patient ID: {{=patientScanRecs[0].patient.id}} </H2> <H2> Diagnostic Group: {{=patientScanRecs[0].patient.DiagnosticGroup}}</H2> <H2> Source:{{=patientScanRecs[0].patient.Source}} </H2> <div class="scanList"> {{for patient_scan in patientScanRecs:}} <div class="scan"> <H2>Age at Scan {{=patient_scan.scan.ageAtScan}}</H2> <H2>Date of Scan {{=patient_scan.scan.dateOfscan}} </H2> <div class="scanImageList"> {{for scan_image in scanImageRecs:}} ... {{pass}} </div> </div> </div> {{pass}} </div>
