I have a model where I want the name in the cards to appear like this:
"45 - My name"
My first thought was to just add a name method to the model to
override the attribute, like this:
def name
return "##{id} - #{self[:name]}"
end
It worked, except for the new/update forms, where the record will load
and then add the id in the name field. In new it would then display "#
-" in the field instead of it being empty. In update it adds the
number to the name field, like this: "#3 - This is a name". Saving
means it will display "#3 - #3 - This is a name", etc.
I then tried to add a full_name method to the model instead, and
wanted to reference that in the card heading instead. This means that
the forms are not affected. So, to get the full-name instead of the
old name I needed to change the card-definition. This is the original
definition that is auto-generated:
<def tag="card" for="Comment">
<card class="comment" param="default" merge>
<header: param>
<h4 param="heading"><name/></h4>
</header:>
<body: param>
<view:body param="description"/>
<a:owner param="creator-link"/>
</body:>
</card>
</def>
Here is my extension in front_site.dryml:
<extend tag="card" for="Comment" >
<old-card class="comment" param="default" merge>
<heading: replace>
<h4 param="heading"><view:full-name/></h4>
</heading>
</old-card>
</extend>
Using this gives the right display-name, but the name is no more a
link. While trying various things here I discovered that the automagic
linking gets lost even if I just try to redefine the heading the same
way it was before:
<extend tag="card" for="Comment" >
<old-card class="comment" param="default" merge>
<heading: replace>
<h4 param="heading"><name/></h4>
</heading>
</old-card>
</extend>
This redefinition makes the link to the record go away too. I found
that very strange indeed... Anyone know why this happens?
Does anyone have a suggestion on how to change the display-name
without any other adverse effects?
Regards,
Ronny
