I have a blog and was hoping to showcase a snippet of my latest blog post on the homepage. I added the blog post object to the homepage, but of course, it presents the entire post on the homepage (making the page very long). Can someone please tell me how I can do this, but show only a snippet (first five lines of post) on my homepage? Thanks in advance!

Hi,
I think you can :
- look at the template called in the homepage
- make an override for this one
- use one this operators (shorten or extract_left): http://ez.no/doc/ez_publish/technical_manual/4_0/reference/template_operators/strings Hope it helps.

Better yet, use the "teaser" operator provided by the xmlwash package, availabel at http://projects.ez.no/xmlwash. It can be seen in action on http://pluspunkt.at (the thumbnail images are also automatically extracted from the blog posts!).

Or you can try to make a new view. It's more in the ez way, I guess :-D http://ez.no/doc/ez_publish/technical_manual/4_0/reference/template_override_conditions

I created an override for my frontpage.tpl file. So how do I use an operator to only display a small portion of the blog post? I'm assuming I have to put something here (in frontpage.tpl) where the blog post is being displayed.
<div class="right-column-position">
<div class="right-column">
<!-- Content: START -->
{attribute_view_gui attribute=$node.object.data_map.right_column}
<!-- Content: END -->
</div>
</div>
THANKS!

You must replace the attribute_view_gui line by something like :
{$node.object.data_map.right_column.content|wash()|extract_left(50)}
Where 50 is the number of chars you would like to keep.

Hmmm, doesn't work for me. Replacing with the following just removed all content from that column:
<div class="right-column-position">
<div class="right-column">
<!-- Content: START -->
{$node.object.data_map.right_column.content|wash()|extract_left(50)}
<!-- Content: END -->
</div>
</div>
I don't consider myself an administrator or coder, so I'm sure I'm just missing something. However, I do appreciate your help, Maxime!

Ah, ok.
It may be hard so. What datatype (Textline, Text block, Image, XML block,...) is used for the attribute right_column ? If you don't know where to find this information, you can look at Setup > Classes > Content > <Name of the content class> > <Attribute with the identifier right_column>

I appreciate this, Maxime.
It says:
"5. Right column [XML block] (id:239)
Name:Right column
Identifier:right_column
Flags:Is not required
Is searchable
Does not collect information
Translation is enabled
Preferred number of rows: 20"
Here is a snapshot of this in my admin:

Now you know that is a XML Block, you can try to show what inside the content attribute object. When you manipulate :
$node.object.data_map.right_column
It refers to an attribute (regarding to the input form, it'sonly the part concerning the right column). Then, you can show what is inside this object using the attribute(show) function.
{$node.object.data_map.right_column.content|attribute(show)}
It will show a table with 3 columns : attribute, type, value. If nothing appears, there's two reasons : maybe what you have passed as value is not a table or maybe it's null.
For each attribute, you can acces its content by just adding ".content". As above.
If my memory is ok, you would have to add ".output" finally to get get only the XML. Then you must process it to extract only what you want (and escape the XML stuff).
{$node.object.data_map.right_column.content.output}
{$node.object.data_map.right_column.content.output|attribute(show)}
Good luck !

Sorry if I wasn't too clear: Of course creating a custom view is needed for the blog snippets. However, the teaser operator lets you get a snippet out of an XMLText attribute.
