Form Criteria

Start with a collection and some content for search results.

>>> from Products.PloneTestCase import ptc
>>> self.login()
>>> foo_topic = self.folder['foo-topic-title']
>>> foo_topic
<ATTopic at /plone/Members/test_user_1_/foo-topic-title>
>>> self.folder['bar-document-title']
<ATDocument at /plone/Members/test_user_1_/bar-document-title>
>>> self.folder['baz-event-title']
<ATEvent at /plone/Members/test_user_1_/baz-event-title>

Create the browser object we’ll be using.

>>> from Products.Five.testbrowser import Browser
>>> browser = Browser()
>>> browser.handleErrors = False

Log in as a normal user.

>>> browser.open(portal.absolute_url())
>>> browser.getLink('Log in').click()
>>> browser.getControl('Login Name').value = ptc.default_user
>>> browser.getControl(
...     'Password').value = ptc.default_password
>>> browser.getControl('Log in').click()

Before the topic has any form criteria, the serach form is not present.

>>> browser.open(foo_topic.absolute_url())
>>> browser.getForm(name="formcriteria_search")
Traceback (most recent call last):
LookupError

Add a simple string form criterion for searchable text on the criteria tab.

>>> browser.getLink('Criteria').click()
>>> browser.getControl('Search Text').selected = True
>>> browser.getControl(name="criterion_type", index=0).getControl(
...     'Form: Text').selected = True
>>> browser.getControl('Add criteria').click()
>>> print browser.contents
<...
...Search Text...
...A simple string form criterion...

Set a default search term.

>>> browser.getControl(
...     name=
...     "crit__SearchableText_SimpleStringFormCriterion_value"
...     ).value = 'bar'
>>> browser.getControl(name="form.button.Save").click()
>>> print browser.contents
<...
...Changes saved...

Open another browser as an anymous user.

>>> anon_browser = Browser()
>>> anon_browser.handleErrors = False
>>> anon_browser.open(foo_topic.absolute_url())

If no form value have been submitted, such as on a fresh load of the topic view, the default term will be used in the query returning only one of the content objects.

>>> len(foo_topic.queryCatalog())
1

>>> anon_browser.getLink('Bar Document Title')
<Link text='Bar Document Title'
url='http://nohost/plone/Members/test_user_1_/bar-document-title'>
>>> anon_browser.getLink('Baz Event Title')
Traceback (most recent call last):
LinkNotFoundError

Now that a form criterion has been added, the topic view displays the search form.

>>> form = anon_browser.getForm(name="formcriteria_search")

Enter a search term and submit the query. The topic will now list the other content object.

>>> form.getControl(
...     name='crit__SearchableText_SimpleStringFormCriterion'
...     '.value').value = 'baz'
>>> form.getControl(name='submit').click()
>>> anon_browser.getLink('Bar Document Title')
Traceback (most recent call last):
LinkNotFoundError
>>> anon_browser.getLink('Baz Event Title')
<Link text='Baz Event Title'
url='http://nohost/plone/Members/test_user_1_/baz-event-title'>

The search form also reflects the search term submitted rather than the default value submitted on the criteria tab.

>>> anon_browser.getForm(name="formcriteria_search").getControl(
...     name='crit__SearchableText_SimpleStringFormCriterion'
...     '.value').value
'baz'

Contents View

Change the topic’s display layout to the contents view.

>>> browser.open(foo_topic.absolute_url())
>>> browser.getLink('folder_contents_view').click()
>>> print browser.contents
<...
...View changed...

The view renders the contents form.

>>> browser.getForm(name="folderContentsForm")
<zope.testbrowser.browser.Form object at ...>

The topic contents are listed in the contents table form.

>>> browser.getControl('Bar Document Title')
<ItemControl name='paths:list' type='checkbox'
optionValue='/plone/Members/test_user_1_/bar-document-title'
selected=False>
>>> browser.getControl('Baz Event Title')
Traceback (most recent call last):
LookupError: label 'Baz Event Title'

The search form is also rendered if form criteria are present.

>>> form = browser.getForm(name="formcriteria_search")

The contents view also reflects user submitted criteria.

>>> form.getControl(
...     name='crit__SearchableText_SimpleStringFormCriterion'
...     '.value').value = 'baz'
>>> form.getControl(name='submit').click()
>>> browser.getControl('Bar Document Title')
Traceback (most recent call last):
LookupError: label 'Bar Document Title'
>>> browser.getControl('Baz Event Title')
<ItemControl name='paths:list' type='checkbox'
optionValue='/plone/Members/test_user_1_/baz-event-title'
selected=False>

TODO

• Additional Criteria

  Currently only some criteria have form criteria equivalents. The intention is to add form criteria for the rest of the ATCT criteria as well. I’m only likely to get to the ones that I need without any further input, so if you want one in particular let me know.

• Form sort criteria

• Use subcollections to support AdvancedQuery operations

  Collections will act as grouping/parenthesis and operators. IOW, a collection will have a boolean field to set whether it uses AND or OR to find the intersection or union of its result sets. Sub-collections will not acquire criteria but instead parent collections will treat sub-collections as criteria groupings. Not yet sure how to handle sorting.
