Batch processing via browser **************************** Preliminaries: We define a function that looks up a form with several submit buttons for the one with a given value (this functionality is missing in zope.testbrowser): >>> def lookup_submit_value(name, value, browser): ... """Find a button with a certain value.""" ... for num in range(0, 100): ... try: ... button = browser.getControl(name=name, index=num) ... if button.value.endswith(value): ... return button ... except IndexError: ... break ... return None Create a site: >>> from waeup.kofa.app import University >>> getRootFolder()['app'] = University() Create a datacenter storage path: >>> import os >>> import tempfile >>> dc_path = tempfile.mkdtemp() Log in: >>> from zope.testbrowser.testing import Browser >>> browser = Browser() >>> browser.addHeader('Authorization', 'Basic mgr:mgrpw') >>> browser.handleErrors = False Set datacenter path and deselect moving old data: >>> browser.open('http://localhost/app') >>> browser.getLink('Data Center').click() >>> browser.getLink('Edit settings').click() >>> browser.getControl(name='newpath').value = dc_path >>> browser.getControl(name='move').value = False >>> browser.getControl(name='save').click() Set non-usable datacenter path: >>> browser.getLink('Edit settings').click() >>> browser.getControl(name='newpath').value = '/' >>> browser.getControl(name='save').click() >>> 'Given storage path cannot be used.' in browser.contents True >>> browser.getControl('Cancel').click() Batch processing faculties ========================== Go to datacenter page: >>> browser.open('http://localhost/app/datacenter') Prepare a CSV file for faculties: >>> open('faculties.csv', 'wb').write( ...
