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()

Add a criterion for the workflow state that won’t appear on the form. Then set the query term to return only published content.

>>> browser.open(foo_topic.absolute_url()+'/criterion_edit_form')
>>> form = browser.getForm(name='criteria_select')
>>> form.getControl('State').selected = True
>>> form.getControl(
...     'Select values from list', index=0).selected = True
>>> form.getControl('Add criteria').click()
>>> print browser.contents
<...
...State...
...Select values from list...

>>> browser.getControl('published').selected = True
>>> browser.getControl('Save', index=0).click()
>>> print browser.contents
<...
...Changes saved...

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

>>> browser.getLink('View').click()
>>> browser.getForm(name="formcriteria_search")
Traceback (most recent call last):
LookupError

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

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

Select the criterion’s ‘value’ field as a form field so it will appear on the search form.

>>> browser.getControl(
...     name='crit__SearchableText_SimpleStringFormCriterion'
...     '_formFields:list').getControl('Value').selected = True

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")

Since the search form has not been submitted, the search form starts out expanded.

>>> 'collapsedOnLoad' in anon_browser.contents
False

Criterion fields that haven’t been selected in “Form Fields” don’t appear on the search form.

>>> form.getControl(
...     name='crit__SearchableText_SimpleStringFormCriterion'
...     '.formFields:list')
Traceback (most recent call last):
LookupError: name
'crit__SearchableText_SimpleStringFormCriterion.formFields:list'

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'>

Since the search form has been submitted, the search form starts out collapsed.

>>> 'collapsedOnLoad' in anon_browser.contents
True

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>

Changelog

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

• Fix folder_contents view to support deleting, etc.

• 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.
