Accessors (on newsItems)

Reply Threaded

Hello,
I would like to write a listing for the news Items in my sitem but I don't know how to access the Text attribut of the newsItems. Is there a possibility to list all accessors of a content type, or is there a good documentation about these accessors and fields of certain types? I already tried this:

tal:replace="obj/getText" tal:replace="obj/Text"
but none of these works.

Furthermore I would like to have the newsItems in an archiv. The archiv should have a lot of pages and on every page there should only be 10 items, then the next 10 and so on. I would like to make a Linklist, where I can navigate to the 20th or 30th NewsItem page. I tried to generate the HTML explicitly with an python script, but that doesn't work, because the html is inserted without being interpreted. Is there a better solution to make such a Linklist?

Pleas help me, especially with the accessor, it's so frustrating to know the information is stored in the newsItem, but not being able to access it.

to get an attribute, you use the get<attrName> concept, with the first
letter of the attribute name being uppercase. But Text might not be
the name of the attribute :) You can look at the schema to double
check. also make sure that obj is actually an object and not a
catalog result.

not sure that I 100% get your second question, but it seems like what
you are looking for is the tal "structure" syntax.

hth,

According to:

#CMFPlone/skins/plone_content/newsitem_view.pt
<tal:main-macro metal:define-macro="main"
tal:define="...
text python:here.CookedBody(stx_level=2);
...">
[...]
<div metal:define-macro="text-field-view"
id="parent-fieldname-text" class="stx"
tal:define="...
text text|here/getText|nothing;
...">

either python: here.CookedBody(parameters) or here/getText should work.

Hi,
eleddy, whats the difference whether it's an Object or a catalog result?
This is how the results are generated:

tal:define="view context/@@news_view;
start request/start|python:0;
results python:view.published_news_items()[int(start):10];
news_link view/all_news_link"
tal:condition="python:test(template.getId()!='news' and results, 1, 0)"

is there a better solution? is the body not part of the delivered objects?

This is how the objects should be used.

Plone 2.1 announced!

Plone 2.1 announced!

Thanks for the help so far.

When you search using the portal_catalog tool, it returns a lazy list
of items called brains. Lazy means here that the objects referenced in
that list are not waken up. Each brain has a series of attributes
consisting of values from the metadata table of portal_catalog you can
use in your listing templates without retrieving the objects.

In this case, results come from the published_news_items() method of
the Products.CMFPlone.browser.portlets.news.NewsPortlet class, which
turns out to return catalog brains.

The view @@news_view is deprecated. I don't know what _should_ be used
instead, but I would use the portal_catalog tool directly.

Thanks a lot, learned something new.
