Ok, thanks for this example. But I still have a problem: Because even
the forms on this page are dynamically allocated, they are stored in a
vector, and because they are not copyable, I store a booster::shared_ptr
to them instead.
I loop with
<% foreach form in forms %>
But the problem is, that now the following construct
<% foreach w as cppcms::form::iterator in form %>
does not work, because the template generator expects form to be the
object itself (and therefore generates form.begin() and form.end()
instead of form->begin() and form->end() which would have to be used
here). Is there a way around this apart of editing the generated
template afterwards?

Thanks,
Julian

Hello Aris, and welcome!

Like you, I am using Ubuntu -64bit. 
Which version of Ubuntu are you using? I had a small problem with the ICU 
version on Kubuntu 09.10 but Artyom promptly fixed it so that now cppcms 
compiles cleanly on this platform with a somewhat older ICU version.

So, my advice is to follow Artyom's advice above. Check the wiki for the 
official list of ubuntu packages to install. Completely delete the build/ 
directory of your cppcms. Make sure you get the latest code from svn.

There is one extra step  that I had to do once to make sure the compiler knew 
to get the extra libraries in /usr/share/local. I forgot what it is, but it is 
in the 'troubleshooting' section in the wiki.

Otherwise, you shouldn't have any problem compiling it using the default 
options. You should start over from scratch.


Good luck,

Augustin.

No, you can't. At least in current API.

Yes you can, read this:

<http://cppcms.sourceforge.net/boost_locale/html/tutorial.html#6f4922f45568161a8cdf4ad2299f6d23>


You need to use iostream manipulator booster::locale::as::domain("name")
to switch domain in the stream.

It is not safe, actually access of any non-const member function
of booster::locale::generator is not thread safe from multiple
threads, see 

<http://cppcms.sourceforge.net/boost_locale/html/classboost_1_1locale_1_1generator.html>


However, you can always create a separate instance of 
booster::locale::generator,
create locale and install it using

http://art-blog.no-ip.info/cppcms_ref_v0_99/classcppcms_1_1http_1_1context.html#9d6ee6ce1d9007ba1c0d7222fa022fd8


Please note, loading dictionaries and creating locale objects
may be quite heavy operation, so use it very carefully.

You may cache such custom locales withing your cppcms::application derived class
that is cached in pool and not created frequently.

Re: [Cppcms-users] Custom form rendering and dynamic widgets

Yes, you can. 

See: http://art-blog.no-ip.info/cppcms_ref_v0_99/classcppcms_1_1form.html

it has forward iterator in it and thus you can iterate over the
form.

There is an example from src/hello_world_view1.tmpl


        <% foreach w as cppcms::form::iterator in form %>
            <% separator %><br/><% item %>
                <% if w.has_message() %><% w.message() %>:<% end %>
                <% form input w %>
                <% if not w.valid() %>:<% w.error_message() %><% end %>

[Cppcms-users] Custom form rendering and dynamic widgets

[Julian P. <ju...@wh...>]

-----BEGIN PGP SIGNED MESSAGE-----

Hallo,

I've a question concerning the custom form rendering. My situation is,
that I have a form which gets filled with widgets at runtime (by a JSON
configuration), so that I don't know which widgets it will contain when
it has to be rendered.
So how can I iterate over the form's widgets in my template to do custom
rendering? <% form input my_input %> won't work here as I don't know how
many widgets there are.
May I use a construct like
<% foreach widget in form %> here?

Thanks,
Julian

Ok, in meantime I found the locale::generator::add_messages_domain() and
set_default_messages_domain(), but that raised a few more questions:

- - Is it possible to remove a message domain again? (But only one and not
all message domains, so the clear_domains() method is not what I want)
- - Can I select the domain to use for basic_format::format or
locale::translate at method call somehow or do I have to call
set_default_messages_domain() on generator beforehand? If this is the
case, is this thread safe, so that I can change the
default_messages_domain even to different values for parallel requests?

I have try to pass --with-pic option into "./configure" command and
"--with-pic" option wasn't recognized. Then I execute "./configure
--help" command to show all acceptable option with "./configure"
command, and there is no "--with-pic" option, as explained in some
article which show how to use PIC in compilation.
How I can compile with -fPIC command? Is it same if I use "--with-pic"
option? I use "--with-pic" command because I don't know yet about
passing "-fPIC" option. I don't know in which command I must pass it
into; in "./configure" or "gcc/g++"?

Re: [Cppcms-users] ICU lib error in building cppcms 64bit environment

[Artyom <art...@ya...>]

Few points for Linux newcomer:

1. Stop working as root! It is very bad habit!

2. Install icu using 

     apt-get install libicu-dev 

   and stop compiling it on your own.

3. Remove all files from build directory and run cmake .. and then
   make again.

If you really what to build ICU on your own, build the default
version without any flags, it would build shared version.

Not, there is not import libraries crap so you link against shared
objects directly. But the code, as you mentioned should be compiled
with -fPIC - make it position independent - suitable for shared objects,
static libraries are usually compiled without this option
as expected to be used in static libraries.

P.S.: There should be no problems on 64 bit platform as I develop it
      mostly on 64bit one :-)



      

Re: [Cppcms-users] ICU lib error in building cppcms 64bit environment

[Aris S. <ari...@gm...>]

Before I install my own ICU, there were ICU library in my "/usr/lib64"
folder, but when I run "make" in my "cppcms/buil" folder, there is an
error explain that some dynamic library need libicuuc.a (a static
library). I have remove all libicu*.a and libicu*.so which I just
install in case to repeat that error. They are:

root@aris-laptop:/opt/cppcms/build# cmake ..
-- Looking for ICU libraries
-- ICU Found, building booster locale
-- Configuring done

-- Build files have been written to: /opt/cppcms/build

Because of errors above, then I build my own ICU to get static ICU library.

I'm new in linux programming and manual compiling. It is not normal
when a dynamically library links against static archives, isn't it?

What about -fPIC errors? I have ubuntu-amd 64-bit environment. In this
link: http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=3#doc_chap7
, descibed about -fPIC errors and explained that on certain
architectures (AMD64 amongst them), shared libraries must be
"PIC-enabled". The error produced by "-fPIC errors" is similar to my
error.

How do you think?

Re: [Cppcms-users] ICU lib error in building cppcms 64bit environment

[Artyom <art...@ya...>]

Hello,

1. I'd recommend using your distribution's ICU rather then
   custom build one, unless you have very good reasons. CppCMS works
   and tested with ICU 3.6 and above and should work even with ICU 3.2.

2. From what I can see you are trying to link libicuuc.a into shared object,
   you can't. You need link shared objects with shared objects.

   It looks like you had compiled only static version of ICU. Take a look
   on what you had installed if you find only libicu*.a and not libicu*.so
   then you need to compile shared version or disable building
   shared libraries of CppCMS (which is very bad idea).

Re: [Cppcms-users] Setting context.locale()

[Artyom <art...@ya...>]

Actually CppCMS's localization is much more
powerful then the localization available in standard C++
library - it uses Boost.Locale - renamed to booster namespace

<http://cppcms.sourceforge.net/boost_locale/html/tutorial.html>


Now, in order to get information about the current locale
you may use following:

<http://cppcms.sourceforge.net/boost_locale/html/tutorial.html#4e732ced3463d06de0ca9a15b6153677>


Generally:

   std::locale current_locale = context().locale();
   booster::locale::info const &inf = 
std::use_facet<booster::locale::info>(current_locale);
   lang = inf.language() // for "my"
   terr = inf.country(); //for "LC"

And so on.

Used hello_locale example to test a bit around, and I realised, that
locale is set correctly, but the currently set locale is not returned by
context().locale(). Instead, the standard locale is returned ("*") I think.
Or do I have to use another call to get the locale's name like
"de_DE.utf-8"?

It depends on your needs and apache configuration. i.e. how
do you add generally or per site. 

I expect some basic knowledge in configuring specific web server 
so I just give a  major points, as the rest is up to the user.

That was useful.

In the "Apache, FastCGI" sections, there are two places where a copy/paste 
operation seems to have failed. In the "Apache, FastCGI, Start by Web Server" 
and the "Apache, FastCGI, Independent start" sections, there is some 
configuration code that is broken up by "unning ...".
I would have fixed it myself if I knew what your intent was.

Obviously, one part must be configured in cppcms's config.js. 

Is all the rest of the configurations in the tutorial supposed to be added in 
fastcgi.conf?
Shouldn't (couldn't) some of it be configured in a file within 
/etc/apache2/sites-enabled/ ?

The aim is to have several scripts (each with their own config.js) running at 
different addresses on the localhost.

Augustin.

Isn't there something missing in that example?

Generally no,

But you always can create custom widgets rendering,
using simple for loop.
See as example code in src/hello_world_view1.tmpl
lines: 13-19, in CppCMS sources.

Yes, after you explain, it always looks simple to me... and I am embarrassed I

I come for a mostly procedural type of programming (Drupal) and I still don't 
always think in terms of classes and sub-classes and method override. My mind 
often goes on the wrong track.

Anyway, for other future newbies like me, I created this simple tutorial:

Did you see my patch on the sourceforge bug tracker ?

is it possible to specify the class argument for the <th> and <td> cells

that e.g. a line like this is produced:

Very simply.

That is the implementation of cppcms::application::main(std::string)
exactly according to this description

void application::main(std::string url)
{
   if(!dispatcher().dispatch(url)) {
       response().make_error_response(http::response::not_found);
   }
}

So just reimplement it the way you want.

Additionally you can just do following:

  dispatcher().assign(".*",&myclass::my404,this)

And make sure it is the last URL you add to the list.

[Cppcms-users] Create own 404 page

[augustin <aug...@ov...>]

Hello,

How to create a custom 404 page.

The doc says:

    virtual void cppcms::application::main   (  std::string   url    )  
   [virtual]
  
   This is main function of the application that is called when it is matched
   according to the regular expression in the applications_pool class. 
   By default, main calls dispatcher().dispatch(url). And if the last fails,
   it creates 404 Error page. This allows developers to create its own hooks
   for reaction on incoming URL as, initialization and cleanup of general
   resources, Custom 404 and error handlers etc. 
   Reimplemented in cppcms::rpc::json_rpc_server.


I don't understand the above explanation.

Following the examples provided in the source, I make use of 
dispatcher().assign() within my application constructor.  
Thus myApplication::main() is no longer called at all. 

I fail to see how to use either myApplication::main() or 
myApplication::myApplication() or even disptacher().assign() to register a 
callback for 404 pages (or for any other codes, inc. access denied...).


Augustin.

Re: [Cppcms-users] Get HTTP Headers of Request

[Artyom <art...@ya...>]

According to CGI specifications you should use 

cppcms::http::request::getenv with "HTTP_WHICH_HEADER"
as parameter

Note, it is up to web server to provide such variable.

See <http://tools.ietf.org/html/rfc3875#section-4.1.18>

Note: some web servers(like Niginx) require a list of specific
headers to be passed explicitly, others may filter them.

So basically you need: request().getenv("HTTP_WHICH_HEADER");

Hi,

thanks for your reply, but this is not the method I need: It will set
custom headers on the response, but I need to gain a custom reader from
the request (i.e. from the HTTP request the client sent). Setting the
custom header (which is done on an Ajax request, btw) is not the problem.
