Language Views
==============
Admin Language
--------------
>>> from zope.component import getUtility
>>> from lp.services.worlddata.interfaces.language import ILanguageSet
>>> from lp.translations.publisher import TranslationsLayer
>>> language_set = getUtility(ILanguageSet)
>>> portuguese = language_set.getLanguageByCode('pt_BR')
>>> language_admin_view = create_view(
... portuguese, '+admin', layer=TranslationsLayer)
>>> language_admin_view.initialize()
The language +admin view provides a label and a page_title for the page.
>>> print language_admin_view.label
Edit Portuguese (Brazil) in Launchpad
>>> print language_admin_view.page_title
Change details
The view provides also a cancel_url and a next_url, but they're the same
because the previous and next steps of editing a language are returning
to its index.
>>> print language_admin_view.cancel_url
http://translations.launchpad.dev/+languages/pt_BR
>>> print language_admin_view.next_url
http://translations.launchpad.dev/+languages/pt_BR
Validation
----------
Plural information entered on the admin page is checked for validity.
>>> language_admin_view.validate({
... 'code': 'pt_BR',
... 'pluralforms': 2,
... 'pluralexpression': '1/n',
... })
>>> print language_admin_view.getFieldError('pluralexpression')
Division by zero in plural expression for n = 0.
Add Language
------------
>>> language_add_view = create_view(language_set, '+add',
... layer=TranslationsLayer)
>>> print language_add_view.label
Register a language in Launchpad
>>> print language_add_view.page_title
Register a language
The view provides also a cancel_url and a next_url:
>>> print language_add_view.cancel_url
http://translations.launchpad.dev/+languages
>>> print language_add_view.field_names
['code', 'englishname', 'nativename', 'pluralforms',
'pluralexpression', 'visible', 'direction']
>>> login("admin@canonical.com")
>>> form = {
... 'field.code': 'lp_US',
... 'field.englishname': 'Launchpad English',
... 'field.nativename': '',
... 'field.pluralforms': '',
... 'field.pluralexpression': '',
... 'field.visible': True,
... 'field.direction': 'LTR',
... 'field.actions.add': 'Add',
... }
>>> language_add_view = create_initialized_view(
... language_set, '+add', form=form,
... layer=TranslationsLayer)
>>> language_add_view.errors
[]
>>> print language_add_view.next_url
http://translations.launchpad.dev/+languages/lp_US
View Language
-------------
Translators lists for each language are computed using KarmaCache tables for
users which have configured their prefered language. Since KarmaCache tables
are generated using nightly builds, we will change Langauge.translators to
use the list of translators generated by this test.
Language.translators is deleted so that we can add our custom
implementation later.
>>> from lp.services.worlddata.model.language import Language
>>> translators_method = Language.translators
>>> del Language.translators
>>> serbian = language_set.getLanguageByCode('sr')
>>> language_view = create_initialized_view(serbian, '+index',
... layer=TranslationsLayer)
The 'friendly_plural_forms' function shows us a list of plural forms and
a set of examples for each one, so one won't need to understand the plural
formula expression to see how it works.
>>> friendly_plural_forms = language_view.friendly_plural_forms
>>> for form_dict in friendly_plural_forms:
... print form_dict['form'], ':', form_dict['examples']
0 : 1, 21, 31, 41, 51, 61...
1 : 2, 3, 4, 22, 23, 24...
2 : 0, 5, 6, 7, 8, 9...
The top contributors are listed on the language page, and for a merged account
we will see their targed account.
Create some translators and a merged account.
>>> from zope.security.proxy import removeSecurityProxy
>>> translators = []
>>> translator_main = factory.makePerson(
... name='translator-main',
... displayname='Translator Main')
>>> translators.append(translator_main)
>>> translator_merged = removeSecurityProxy(factory.makePerson(
... name='translator-merged',
... displayname='Translator Merged'))
>>> translators.append(translator_merged)
>>> translator_merged.merged = translator_main
>>> for translator_nr in range(22):
... translators.append(factory.makePerson(
... name='translator-' + str(translator_nr),
... displayname='Translator No.' + str(translator_nr)))
Create a product, a template with one msgset and a pofile
>>> from lp.app.enums import ServiceUsage
>>> product = factory.makeProduct(
... translations_usage=ServiceUsage.LAUNCHPAD)
>>> template = factory.makePOTemplate(
... productseries=product.getSeries('trunk'))
>>> potmsgset = factory.makePOTMsgSet(template)
>>> pofile = factory.makePOFile('sr', potemplate=template)
Add a translation for each translator and one more for main and merged
accounts.
>>> for translator in translators:
... translation = factory.makeCurrentTranslationMessage(
... pofile=pofile, translator=translator, potmsgset=potmsgset)
>>> translation = factory.makeCurrentTranslationMessage(
... pofile=pofile, translator=translator_merged, potmsgset=potmsgset)
>>> translation = factory.makeCurrentTranslationMessage(
... pofile=pofile, translator=translator_main, potmsgset=potmsgset)
Langauge.translators is Monkey-patched to avoid fetching KarmaCache.
Language.translator is a list containing all contributors decreasingly sorted
according to their karma value.
>>> serbian.translators = translators
>>> language_view = create_initialized_view(serbian, '+index',
... layer=TranslationsLayer)
>>> top_contributors = language_view.top_contributors
>>> translator_main in top_contributors
True
>>> translator_merged in top_contributors
False
>>> for translator in top_contributors:
... print translator.name
translator-main
translator-0
translator-1
translator-2 ...
In the end, the changes done to Language class are reverted.
>>> Language.translators = translators_method
View LanguageSet
------------------
>>> login('carlos@canonical.com')
>>> languageset_view = create_initialized_view(language_set, '+index',
... layer=TranslationsLayer)
The user_languages property contains a list of the current user's preferred
languages formated as links.
>>> print languageset_view.user_languages
<a href=".../ca" ...>Catalan</a>,
<a href=".../en" ...>English</a>,
<a href=".../es" ...>Spanish</a>
For a user without any preferred languages, English will be returned.
>>> person = factory.makePerson()
>>> print person.languages
[]
>>> login_person(person)
>>> languageset_view = create_initialized_view(language_set, '+index',
... layer=TranslationsLayer)
>>> print languageset_view.user_languages
<a href=".../en" ...>English</a>
