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
<Topic 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()

Change the display layout of the collection to the “Search Form”.

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

Go to the collection’s edit tab and set the “Form Results Layout” field.

>>> browser.getLink('Edit').click()
>>> browser.getControl('Collection').selected = True
>>> browser.getControl('Save').click()
>>> print browser.contents
<...
...Changes saved...

Go to the “Criteria” tab and 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.getLink('Criteria').click()
>>> 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...

Open another browser as an anymous user.

>>> anon_browser = Browser()
>>> anon_browser.handleErrors = False

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

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

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

>>> 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...

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.open(foo_topic.absolute_url()+'/atct_topic_view')
>>> 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” layout is used, 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='form_crit__SearchableText_SimpleStringFormCriterion'
...     '_formFields:list')
Traceback (most recent call last):
LookupError: name
'form_crit__SearchableText_SimpleStringFormCriterion_formFields:list'

The label for the criterion corresponds to the form element for the firs criterion field.

>>> ctl = form.getControl('Search Text')

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

>>> ctl.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 from the “Search Form” layout, the results are rendered on the layout specified by the “Form Results Layout” field and the search form starts out collapsed.

>>> anon_browser.url.startswith(
...     'http://nohost/plone/Members/test_user_1_/foo-topic-title'
...     '/atct_topic_view')
True
>>> '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.

>>> form = anon_browser.getForm(name="formcriteria_search")
>>> ctl = form.getControl('Search Text')
>>> ctl.value
'baz'

If the search form is submitted from this page, the results are still rendered on the same view.

>>> ctl.value = 'bar'
>>> form.getControl(name='submit').click()
>>> anon_browser.url.startswith(
...     'http://nohost/plone/Members/test_user_1_/foo-topic-title'
...     '/atct_topic_view')
True

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='form_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

• 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.
