Accessing tapestry request params outwith a page

2012-11-26 Thread dkeenan
Hi. I have a utility class that I call from within my application. Is it
possible to access the current request and requests parameters from within
my utility class so I can access form parameter values that were uploaded in
the current request?

Nice. I was thinking I could only inject a request into a page class. So I
can inject the request anywhere in the application? Great. Thanks.

Re: Accessing tapestry request params outwith a page

2012-11-26 Thread dkeenan
...just out of interest. Am I correct in thinking that form parameters for a
Tapestry form upload are not stored in the usual HttpServletRequest
parameters?

The reason I ask is that I was originally accessing the HttpServletRequest
object, to try and get to the form parameter I was looking for. From memory,
I think that my HttpServletRequst only had a parameter called 'f:formdata',
rather than each parameter of the form.

Does tapestry actually put submitted form fields into a single
HttpServletReqeust parameter when a form is submitted? If so, is this why we
inject a tapestry Request class to get access to the form parameters, rather
than accessing them from the original HttpServletRequest (as they would
actually be bundled within one parameter at that stage)?

Not sure if I'm way off the mark with my thinking there ^^^

Re: Adding a progress listener to UploadedFile

2012-11-23 Thread dkeenan
Thanks. I wasn't able to use the following annotation and method...

@Contribute(ServiceOverride.class)
  public static void
setupApplicationServiceOverrides(MappedConfigurationClass,Object
configuration)
  {
configuration.addInstance(SomeServiceType.class,
SomeServiceTypeOverrideImpl.class);
  }

I have a suspicion I am on an earlier version of tapestry 5 (I am still on
5.1.0.5).

I have managed to override MultipartDecoderImpl in a very hacky way which
has allowed me to set the progress listener. It's an early POC I'm doing so,
happy that it works, but will look into upgrading tapestry soon if need be.

Thanks for your help.

Hi there. I would like to add a progress listener to UploadedFile to track

Setting element value from an attribute

2012-08-20 Thread dkeenan
Hi. When creating dynamic content in a TML template file I normally do
something like this:

${user.email}


So when running the template in my tapestry app, I get a header with the
logged in user's email address.

But, when viewing the template outside of tapestry, as a normal file,
obviously I get ${user.email} shown in the header.

I really like being able to design my templates outside of the application
and I would like to have something like this:

testu...@test.com
 

Is there a way of doing something like that so that my template looks okay
when viewed outside of the application, and the element is updated
appropriately when running inside the app?

Many thanks,

Dave.

Adding a dynamic sub directory to URL 

2012-07-17 Thread dkeenan
Hi folks. I am writing a web app to be used by a number of clubs. Each club
can register and create a gallery page and a contact page. Both pages will
then be public. 

I each clubs pages to be viewable from the following urls:

http://localhost/club_url_friendly_name/gallery
http://localhost/club_url_friendly_name/contact

When someone browse to either of the urls the app uses the first part of the
path (club_url_friendly_name) to set the appropriate club in the session and
show the appropriate club page. 

Basically I want to give the impression that each club has its own sub-dir
in the application.

Does anyone know if there is a way of achieving this?

Many thanks,

David.

Using layouts - partial page templates

2011-09-15 Thread dkeenan
Hi there. I'm looking to create a Layout.tml template file to hold the
header/footer/navigation elements of my page, and then create the content
within separate files such as Index.tml, About.tml

Obviously, at the moment, when viewing these files outside of Tapestry, they
just show a snippet of html. It is only when running under tapestry that it
fills in the surrounding header/body at runtime using the Layout.tml
template and replacing the t:body/ element.

So far so good. But I would like Index.tml and About.tml to look complete
when viewed as plain files (not running under tapestry), to help our
designer. Therefore I would like Index.tml and About.tml to have all the
complete header/body elements.

I tried putting t:remove tags around the html in these files that I want
tapestry to ignore at runtime (so it can replace them with the contents of
Layout.tml. But this doesnt seem to work. Is there another way to achieve
what Im trying to do? 

Many thanks,

David.

Re: Using layouts - partial page templates

2011-09-15 Thread dkeenan
Hi. the trouble is when I try to escape everything around the main content..
eg. if the About.tml looks a bit like this...

html
head

/head

body
about text
/body

html

I want it to have all the body/head tags in the TML file as above, so it can
easily be viewed outiside of tapestry.

But, i want tapestry to use Layout.tml to fill in everyting outside of the
content, when running live. So i tried doing this approach...

t:remove
html
head

/head

body
/t:remove

about text

t:remove
/body

html

/t:remove


I was hoping that tapestry would remove the surrounding html at runtime, and
fill this in using the HTML for my Layout.tml template. But tapestry doesnt
like removing the above sections as the elements inside the remove tags dont
have matching open close elements.

I know this seems like a really long winded way of doing what I want but I
cant find anyting simpler. Essentiall i jsut want to have a bunch of TML
files that can easily be viewed in a browser (nice for the designer), but
then Tapestry strips out the nav bar at the top and the footer etc. and
replaces them with ones from Layout.tml.

I wanted to do this so I know that all pages have the correct up to date nav
bar/footer when running live, but the designer can still design against full
html pages?


Thanks again,

David.

How do I add a dynamic number of forms to a page?

2011-08-07 Thread dkeenan
Hi there. I have a page on which I want to have a number of forms, one for
each person. The forms will have forename, surname, etc... the usual fields.

However, I wont know how many person forms I want on the page until runtime.
At the moment it seems that I need to have a @Component on my page class for
each form like this...

@Component
private Form personForm;

And also a property for each form field...

@Property
@Validate(required)
private String surname;

If I add two person forms to my page, it looks like I will need to add extra
components to my page class code. But this won't work if I want to make the
number of forms on the page flexible as it will be hard coded wont it?

Is there no way that I can have many forms on the same TML template, with
the same name... and which ever one gets submitted, is the one that gets
processed by the page class?

If I could do this, all I need to do is add a hidded ID field to each form
to determine which user to update in the database. But this doesnt seem
possible. If I try to add 2 forms with the same t:id values in the TML file,
I get this error...

Exception assembling embedded component 'personForm' (of type
org.apache.tapestry5.corelib.components.Form, within MyPage): Component
MyPage already contains a child component with id 'personForm'


Here is my page class code...

public class MyPage {

@Component
private Form personForm;

@Property
@Validate(required)
private String forename;

@Property
@Validate(required)
private String surname;

@Property
private String personId; //Hidden form field to determine which person 
to
update



Here is the TML that I am using...

 form name=personForm id=personForm t:id=personForm
  p
input type=hidden name=personid id=personid
t:id=personid t:type=personid t:value=//value set as person id / 
  /p
  p
label for=forename class=labelForename:/label
input type=text name=forename id=forename
t:id=forename t:type=TextField t:value=forename / 
  /p
p
label for=surname class=labelSurname:/label
input type=text name=surname id=surname
t:id=surname t:type=TextField t:value=surname / 
  /p
 /form


Any help or alternative suggestions would be much appreciated.

Cheers!!!

Select component... Can i just pass it a list of values?

2011-08-07 Thread dkeenan
Hi. Is there any way I can create a select field and get is just to use the
options listed in the html?

The values I have are never going to change and Im happy with the list in
the TML.

Eg... I have...

 form t:id=search_form name=search_form
  p
label for=employeeType class=labelEmployee Type:/label
select style=width:178px; t:type=select t:model=???
t:value=employee_type 
  option value=anyAny/option
  option value=permPermanent/option
  option value=tempTemp/option
/select
  /p

Obviously this complains that I dont have a t:model specified.   But I dont
want to really have to create a Select Model and Enum in Java to back this,
when I really jsut want the values 'perm' and 'temp' already in my template
above. Do I really need to create 2 or more Java classes with and an enum
just to show this list of options that Ive already defined in the TML?

Any help appreciated.


Thanks!!!

Dave.

Yesss!. Tapestry seems to take care of it if I just create a loop. So I can

URL used for localization seems to have locale in path?

2011-06-22 Thread dkeenan
Hi there. When using localization to display different template files based
on the locale, it seems to ad the locale to the URL. Is that normal
behaviour?

Eg. I have 2 homepage files... Home_en.tml and Home_fr.tml.

If I set the locale to French, and go to the homepage, if goes to URL
/fr/Home rather than /Home. The problems is that may page uses relative CSS
paths which mean it doesn't display correctly. If I want to share css files
between 2 different templates in this case, it gets a little messy. Does it
look like Ive done something wrong?

Many thanks,

Re: Can you dynamically select which page template to return?

2011-06-20 Thread dkeenan
Thanks Lewis. I can see what you mean. It does sound like I'm trying to do 
something action-oriented/Struts-like. I'm a big fan of the way Tapestry 
doesn't force you to think in this way and is more intuitive. The reason I ask 
actually, is more to do with wanting to re-skin pages based on a user. Ie. want 
the same content (so just need one page class), but Id like to use a different 
TML file altogether based on the user.
This way, I am hoping to work on 2 separate TML files in design mode, and the 
can be served based on which type of user is logged in. For example... a funky 
design versus a more mature design based on the age of the user. Sounds weird 
:-), but just wondering if there's an easy way to select the TML file at run 
time, that Tapestry uses with a single page class. I think the localization 
functionality would actually do just the trick if I just assign the funky 
styled tml file to one (eg. HomePage_fr.tml) and the refined one 
(HomePage_en.tml).

Then I can programatically set the local based on the logged in user. Does that 
sound like a completely deranged way of going about it? :-)

Thanks, 
Dave.

It's easy to make a single page dynamic, or to choose one of a number

of different pages to render the response.  I feel you may be sticking

too much to the action-oriented framework's view of actions  views;

in Tapestry a page is the combination of an action and a view. This

drives a lot of what Tapestry does for you, in terms of convention

over configuration, and all the plumbing and request handling that the

framework does automatically.


It's a good idea to backtrack from I need to select two different

output views back towards the actual user requirement or story. For

instance, I need to display input validation errors can be a

condtional portion of a single page.  Many other cases can be handled

in terms of having pages with different responsibilities. It's rather

hard to provide guidance in a vacuum.




 I was wondering if I can have more than one possible TML file for a page...

 and programatically decide which one to use?



 Hope makes sense.

Thanks Lewis. I can see what you mean. It does sound like I'm trying to do
something action-oriented/Struts-like. I'm a big fan of the way Tapestry
doesn't force you to think in this way and is more intuitive. The reason I
ask actually, is more to do with wanting to re-skin pages based on a user.
Ie. want the same content (so just need one page class), but Id like to use
a different TML file altogether based on the user.

This way, I am hoping to work on 2 separate TML files in design mode, and
the can be served based on which type of user is logged in. For example... a
funky design versus a more mature design based on the age of the user.
Sounds weird :-), but just wondering if there's an easy way to select the
TML file at run time, that Tapestry uses with a single page class. I think
the localization functionality would actually do just the trick if I just
assign the funky styled tml file to one (eg. HomePage_fr.tml) and the
refined one (HomePage_en.tml).

Then I can programatically set the local based on the logged in user. Does
that sound like a completely deranged way of going about it? :-)

Thanks, 

Dave.

Thanks Thiago. Yeah I see what you mean also. Ideally the HTML should be the
content, and be completely separate from styling (that's CSS's job). This is
exactly how it should be done as you say, but I'm also keen to reuse
existing HTML templates without having to re-factor too much (some changes
would def be needed of course, but I'd rather avoid having do a major
re-write of existing designs I have). I'm more looking to resuse my existing
designs, but plug them into the same backend page class as they will be
using the same data (just doing slightly different things with the data).

I do like the idea of using the localisation functionality that Tapesty has.
Just feels a little weird as I know that's not it's purpose.

Thanks.

Dave.

Sounds great. I'll take that approach in that case. Thanks for your help.

Re: Can you dynamically select which page template to return?

Hi. I just gave that a go, using localization to serve a different TML
template. Started by adding following lines to AppModule:

public static void contributeApplicationDefaults(
  MappedConfigurationlt;String, Stringgt; configuration) {

configuration.add(tapestry.supported-locales, en,fr);
}

Then set locale programatically:

@Inject 
private PersistentLocale localeService;
.
.
.
localeService.set(new Locale(fr)); (did this in Activate method of a super
Page class that all my page classes extend.


I have a page called Home.tml (Backed by Home.java which extends Page.java)

I renamed Home.tml to Home_fr.tml.

When I try to access this page however the broser navigates to /fr/Home. I
was thinking that it should just display /Home in the URL as before, but
serve the html from the new template file (Home_fr.tml)?


Thanks again!!
