Trying to figure out object relation, but documentation is pretty weak

Wednesday 12 May 2004 12:46:27 pm

I'm trying to come up with a way to do a site for a group that wants a directory that's laid out in sort of menu fashion.

Thing of it this way:

I have business-1 that does several services:
service-1, service-2, service-3, service-4

I have business-2 that does several services:
service-1, service-2, service-3

and so on. For each service I will need a price and description.

SO I thought I could have a class for the busineses and a class for services. But how do I point each service I enter to the business to which it belongs? I can't wrap my noggin around this yet. I think I'm confused over classes and groups and that such thing.

There is almost no documentation on Object Relations in the doc pages!

Thanks for any help you can offer.

Hi

Some quick tips. Check that anonymous users are allowed to view the new Resturant class (admin - users -roles -anonymous roles - to * * * for DEVELOPING only. Remember to click the store button!

Secondly check the fetch in your template.. Does it have an class_id, XX or class_filter_array, XX Where XX is an number (the id of the CLASS to fetch.

Cheers

Ok, I'm looking at the restaurant and it says: "Default object view. Click to create a custom template, Node ID: 217, Object ID: 304" and it's all ugly nad barely formatted and it has all sorts of adminstrative-type links on it that I'm sure the anonymous user should not be seering.. I assume I must have to create a new template for the Restaraunt class I created. So, I click on "Click to create a custom template" and it takes me to:

> Error / kernel (1)
Template view /node/view/full.tpl

Default template resource design/standard/templates 
[user    ] [Set]
[Create New] [Update] [Remove]

In the drop down do I want want user, admin, demo, news or news_admin?

I imagine I want user since I want to ceate a template for the users to see. So I click on Create New

I'll call it restaurant.tpl why not?

Overide keys:
Class Restaurant
Section Any
Node (blank)

I want to copy the Article base template, so I select Copy of default template.

Permission denied. Let's try from the admin site.

news_admin > Advanced > Templates

I see a list, but no way to create a new one.

Ok, did all the above again, and copy/paseed the template from article.full into the new restaurant template.

Now, it looks like the article does, but I no longer have a list of the Menu items that were listed under the original default layout. Hmmm. :)

Will I have to create a template for the Menu class specically for listing it in the restaurant.full template or is that something I can do ffrom withiin this one?

Ok, slowly but not-so-surely getting this. ALthough whoever named this "ez" and wrote that there's no need for HTML or programming was smoking crack. :)

On this link:
http://nolagay.com/ezpub335/index.php/news/restaurants/italian/vincent_s_restaurant__1

I have my before and after templates (which I admit is just the default Article template with some addition - but hey, I'm proud I figured that much. Now what I'm trying to do is format the listing of children so that users, instead of looping through and displaying the default::

 Name  	 Class  	 Section  	 Copy
{where'd it get the name?) $Child:item.object.class_name $Child:item.object.section_id etc...
{where'd it get the name?) $Child:item.object.class_name $Child:item.object.section_id etc..

I'd like users to get:

Menu Item                  Price
$Child:??????.item_name       $Child:?????.item_price
$Child:?????.item_description

I've tried $Child:item.object.item_name, $Child:$content_version.data_map.item_name, $Child:data_map.item_name, $Child:item_name and of course, nothing. I'm looking through the documentation, but I just don't understand these templates at all.

Ok, I've tried this:(which I got from this link: http://ez.no/ez_publish/documentation/customization/tips_tricks/fetch_function_examples )

{section loop=fetch( 'content', 'list', hash(parent_node_id, $node.node_id)}

<a href={$:item.url_alias|ezurl}>{$:item.item_name}</a><br>

{/section}

And this isn't working either. I swear, I'm trying!

Well, in your above example, you used

{section loop=fetch( 'content', 'list', hash(parent_node_id, $node.node_id)}

<a href={$:item.url_alias|ezurl}>{$:item.item_name}</a><br>

{/section}

Change that to:

{section loop=fetch( 'content', 'list', hash(parent_node_id, $node.node_id)}

{$:item|attribute(show,2)}
<a href={$:item.url_alias|ezurl}>{$:item.item_name}</a><br>

{/section}

and you'll see everything in the object. (If nothing show up, then it's probably because there's nothing returned by the fetch.)

You are missing a closing ")" in the first line.

Should be:

{section loop=fetch( 'content', 'list', hash(parent_node_id, 217))}
{$:item|attribute(show,2)}
<a href={$:item.url_alias|ezurl}>{$:item.item_name}</a><br>
{/section}

Earned another beer maybe :-)

See

http://ez.no/ez_publish/documentation/reference/template_operators/miscellaneous/attribute

for an explanation. One thing is wrong in the docs: the default is not unlimited but set to 2.

I'll correct this
