Roles & Classes and the fetch function ...

Friday 03 October 2003 6:01:37 pm

I've a problem with the User Roles & Classes and another one with fetch function:

I created a new Class ('trainer') with a few attributes ('surename', 'age', ...). I added the Class 'trainer' to the Role Anonymous as it is shown here: content read Class( Folder , Info page , ... , trainer ).

Two Problems:

- I don't see objects of this new class with my user Anonymous. I see them, when i'm logged in and when i add a '*' instead of Class ( ... ). What am I doing wrong?

- I want to show the attributes of all 'trainer' on one page. So i created a fetch function
fetch('content','list',hash(parent_node_id, $node.node_id,
class_filter_type, include,
class_filter_array, array( 14 ) ) )}
How will i get access to all the attributes of this class. I tried it with {$trainer_list:item.surename} and {$trainer_list:item.age}, but i don't get the content written in these text fields.

Thank you for your help,
greetz, Thomas

Hi,

can you show us your complete template block?

Your problem seems to be with the section block, which you did not post.

Either you have none or it is somehow wrong.
For accessing Items in the $trainer_list, you must contruct a section like
{section name=Trainers loop=$trainer_list}
and then access the items like $Trainers:item and the attribues as $Trainers:item.age

You might want to refer to this code about the section and the variable naming (from News Pagelayout, showing the news box, simplified):

{let news_list=fetch( content, tree, hash(
parent_node_id, 2,
limit, 5,
sort_by, array( published, false() ),
class_filter_type, include,
class_filter_array, array( 2 )) ) }

{section name=News loop=$news_list}
<p class="readmore"><a href={concat("/content/view/full/", $News:item.node_id, "/")|ezurl}>{$News:item.name|wash}</a></p>
{/section}

{/let}

Let us know, if it works.

PS: The role problem was probably, that you didn't close your browser window. When you change roles, I guess, they are only checked, when you log in. Even an anonymous user is "logged in" (automatically) and gets a session. Close the browser and open the page again. This should give you a new session and check your permissions/roles again.

Hm, when you can access .name and .node_id, then your namespaces are fine. With that, you access the node (not the object, yet).

Now, for accessing the object attribute data, you should be able to just print $Trainers:item.data_map.age (so, sorry, my first posting was wrong: You must access the datamap first).
Provided, that this is a simple attribute (no XML), this should work.
If it is more complex, you must use
{attribute_view_gui attribute=$Trainers:item.data_map.age}

You should consider another option:
Use the function node_view_gui to view the Trainer items in the section (search docs for "node_view_gui" for more info).
You will need something like:
{node_view_gui view=line content_node=$articleLoop:item}
ez should then print the "Trainer" node incl. all attributes. Then, you should override the line template of your class to print it nicely. Do this in Admin -> Setup -> Template -> node/view/line and create an override template for your (user) siteaccess, matching your new class (Trainer)
