Newbee - putting it all together...
Hi folks!
I am new to Tapestry and I have one important question that would help me to
put all the bits and pieces together to get a clearer Tapestry picture.
I am trying to do a discussion board using tapestry.
I extend from BasePage a "DiscussionBoardBasePage."
Within this BasePage I implemented a getter method called getIPAddress()
that will return the current IP address from a user (in order to prevent
flooding with messages).
// "Your ip address is 112.61.121.12" for instance
// BasePage
public String getIPAddress(){
return
this.getRequestCycle().getRequestContext().getRequest().getRemoteAddr();
}
// Welcome.html
Your ip address is <span jwcid="@Insert" value="ognl:IPAddress"/>.
// Welcome.page
<page-specification
class="org.apache.tapestry.pets.presentation.pages.WelcomePage">
<property-specification name="iPAddress" type="java.lang.String"/>
I have the feeling I missed something important.
Anyway, I am a bit confused still and need some pointing into the right
direction.
I would like to be able to access the ip address on every page....
Any help is welcome!

Thanks everyone for the help!
It is working this way...really easy - just a getter method and you can
start using it, which is cool.
But what about components?
Assuming I wanted to display/access an ipaddress (just as an example, it
could be anything really)
within components.....
Would I extend BaseComponent and add a method that will call getPage() and
then the previous method getiPAddress() ?
What is the easiest/laziest(!) way of having access to the ipaddress in all
components without the need
of specifying it in every single component specification?

hey sarah,
you are on the right way.
all your pages can now extend from your DiscussionBoardBasePage and you
are able to access the getter.
however, you don't have to specifiy ipaddress in your *.page file.
if you specify ipaddress in your page file, a getter/setter and the
property ipaddress will be automatically created by tapestry.
this is what you don't want in your case.
just remove
<property-specification name="iPAddress" type="java.lang.String"/>
and let the getter where it is, extend you pages from
DiscussionBoardBasePage and you will be fine.
hope that helps
andreas
if you want to access your ip getter from every page, you could create a

Sarah,
> <property-specification name="iPAddress" type="java.lang.String"/>
You do not need this property specification line. iPAddress isn't an
instance variable on the page, it's really just a helper method that returns
the client's ip address.
> Your ip address is <span jwcid="@Insert" value="ognl:IPAddress"/>.
I think there might be a case sensitivity problem here. Try
value="ognl:iPAddress".
Hope this helps,
eric

<property-specification> is to create a NEW property. There's no need for it, because you are
creating a synthetic (that is, a calculated, read-only) property in your base class.
Just ensure that WelcomePage extends from your BasePage class (that class that provides the
IPAddress property).
You said it didn't work, but you didn't say how. Please see:
