Hi,

what Object Relation Mapping (ORM) library should I choose for my CppCMS
application?

Tero

Two things.

1. This exception is thrown when you try to access a file (cppcms::widgets::file::value()) 

   and the file was not uploaded.

   You can check if the file was uploaded by using cppcms::widgets::file::set() member function
   before using value.

   See: http://cppcms.com/cppcms_ref/latest/classcppcms_1_1widgets_1_1file.html#a56ee053415b1bd98944bb3599e3392b1
2. To debug this problem you should be able to see full stack backtrace 
   in the log - and AFAIR it should work under Mac OS X, if not tell me.

   To check if backtrace works, please compile 

      booster/lib/backtrace/test/test_backtrace.cpp

   As g++ -O0 -dynamic booster/lib/backtrace/test/test_backtrace.cpp -lbooster

   And see if you get stack trace when you run the program.

Hi -- I'm trying to develop an image server which raises the following
error when I send a post request to create a new file:

2012-04-22 20:55:28; cppcms, error: Caught exception [File was not loaded]
0x10176c2b3: cppcms::cppcms_error::cppcms_error(std::string const&) + 0x63
in /usr/local/lib/libcppcms.1.dylib
 (http_context.cpp:139)

Could anyone offer me any advice on good ways to start debugging to find
the source of the error, here?
Thanks,
   Doug.

Ah, well I was too dumb to know I wasn't being dumb, then.
Which I'll leave as a paradox to unravel another time ... ;)
Thanks very much for the link, there!

Not a dumb question, and your solution is not correct:

but there is an answer:

Okay, dumb question, sorry!
I just did it by changing the "script_names" config param to [ "/"]
-- I thought I'd struggled with this before, but I guess not. :)

Hi -- all of the tutorials seem to use a non-root directory (such as
"hello/" or "myapp/") as the root for the application.
Is it possible with cppcms to have the root directory be the application
root?
So that, for example, I could make the hello world application run in the
browser from "http://localhost:8080/"?
Cheers,
   Doug.

My bad, i should have read it more thoroughly. Highlighting it would be
great too.

It is in Doxygen API:

http://cppcms.com/cppcms_ref/latest/classcppcms_1_1session__interface.html#details

Quoting:

    All changes in session should be done before headers are written
   to the output (before requesting an output stream from http::response object)

Also It seems that it should be more "highlighted" there.

Because it is quite FAQ there.

I figured that out while reading the header file for session_interface. Do
you think it may be handy to include that in the doxygen API
documentation? Or maybe have it spit out a warning?

Thanks!

... since i asked something that RTFM could have solved, i wrote the 
RESTful WS example (attached). i hope that's what everybody has in mind. 
i am open to learning.

a couple of things i have yet to figure out:

if (request().request_method() != "GET") ...

if (request().content_type() == "application/xml") ...

gave me errors at compilation time:

g++  -I include -c -O2 -Wall -g src/base_rest_ws.cpp -o obj/base_rest_ws.o
src/base_rest_ws.cpp: In member function ‘bool 
base_rest_ws::is_request_method_get()’:
src/base_rest_ws.cpp:39:15: error: invalid use of incomplete type 
‘struct cppcms::http::request’
/usr/local/include/cppcms/application.h:41:9: error: forward declaration 
of ‘struct cppcms::http::request’

g++  -I include -c -O2 -Wall -g src/users.cpp -o obj/users.o
src/users.cpp: In member function ‘void users::count()’:
src/users.cpp:78:38: error: invalid use of incomplete type ‘struct 
cppcms::http::request’
/usr/local/include/cppcms/application.h:41:9: error: forward declaration 
of ‘struct cppcms::http::request’

maybe somebody can set me straight on those.

cheers!

... since i asked something that RTFM could have solved, i wrote the 
RESTful WS example (attached). i hope that's what everybody has in mind. 
i am open to learning.

a couple of things i have yet to figure out:

if (request().request_method() != "GET") ...

if (request().content_type() == "application/xml") ...

gave me errors at compilation time:

g++  -I include -c -O2 -Wall -g src/base_rest_ws.cpp -o obj/base_rest_ws.o
src/base_rest_ws.cpp: In member function ‘bool 
base_rest_ws::is_request_method_get()’:
src/base_rest_ws.cpp:39:15: error: invalid use of incomplete type 
‘struct cppcms::http::request’
/usr/local/include/cppcms/application.h:41:9: error: forward declaration 
of ‘struct cppcms::http::request’

g++  -I include -c -O2 -Wall -g src/users.cpp -o obj/users.o
src/users.cpp: In member function ‘void users::count()’:

cppcms::http::request’
/usr/local/include/cppcms/application.h:41:9: error: forward declaration

maybe somebody can set me straight on those.

cheers!

You can't do changes in session **after** writing **any** output
(including just accessing to response().out() without actual I/O)

Because it allows to use lazy evaluation, caching etc... You will not find many
const member functions in general withing CppCMS for this reason.

The error is reported as any error in istream parsing: failbit.

Read about error handling for C++ I/O stream

Artyom

I've just added a simple message to be displayed on website.

ie.
session().set("msg", "User Updated");

And then in my content class I have a get_message() function which gets
called from inside a template.

get_message() does simple -

string msg;

if (app().session().is_set("msg")) {
    msg = app().session().get("msg"); //works
    app().session().erase("msg"); // doesn't work
}

return msg; // always returns text because it never gets erased

Is modifying a session via app().session() not permitted or is it a bug?
Erasing the key from controller works fine.

Another question - why is session_interface::get() not const?

Cheers,
Petr

Aaah excellent.

What happens if the time string doesn't match the format? ie. the
time/date is 2001/12/01 and ftime is set to %Y-%m-%d

Is there a way to check for such failure(ie. does it throw?)

Thanks!

thx artyom!

i should have re-read the product planning page. i am looking forward to the 
rest support that does handle the scope and the encoded parameters. i was 
just lately looking at other c++ web frameworks that allow you to register a 
class and its methods to handle the rest call and get the scope and 
parameters resolved and fed.

great many thanks!

It works, with manipulators:

ss >> booster::locale::as::ftime("%Y-%m-%d") >> dt;

It requires CppCMS to be compiled with ICU.

Artyom

On the other hand would this work? ( i don't have a C++ compiler on this
windows laptop to try it)

double t;
istringstream is("2001-12-12");

is >> as::ftime("%Y-%m-%d") >> t;

date_time dt(t);

Petr

Does this work for both string-to-date_time as wells as date_time-to-string?

I'm aware of strftime, and all, but that's in reverse. I'm looking for
something like time_input_facet that's in boost::posix_time allowing me to
parse a string/char into time.

Perhaps something like

istringstram ss("2001-12-12");
date_time dt;

ss >> format("%Y-%m-%d") >> dt;

would be really handy. The examples of date and time formatting on the
page you pointed out seem to only show output streams (date to string
formatting), but maybe I'm not seeing something obvious in which case I
apologize.

Note, today it is really not a problem to implement RESTful web 

services with CppCMS.

Note REST is not a protocol like "JSON-RPC" is just
general guidelines.

So:

1. Create a mapping between resource and function/application
2. Handle requests differently for PUT/GET/DELETE etc.

  void myhandler(std::string resource_id)
  {
    if(request().method() == "GET") {
      ...

    }
    else if(request().method() == "PUT") {
      ...

    }
    else if(request().method() == "DELETE") { ... }

  }

And so on, so RESTful service implementation with CppCMS
is quite trivial.

To parse date-time read

http://www.boost.org/doc/libs/1_49_0/libs/locale/doc/html/formatting_and_parsing.html

Just change "boost" to "booster"

Note to parse booster::locale::date_time you need to compile CppCMS with ICU.

Otherwise you can use booster::ptime and std::tm <-> booster::ptime/time_t conversions.

http://cppcms.com/cppcms_ref/latest/classbooster_1_1ptime.html#a5d69b8e68c9847834ee984bfd19be8b5

Note this mostly related to forms/widgets. CppCMS supports date-time parsing.

If I understand well, this function provides a string from a time_t.
And if I understand well Petr's original request, he wants the opposite: get a 
time_t from a string.
I'm sure there's an easy solution somewhere, a simple third-party API.

In any case, there seem to be a relevant item in CPPCMS' roadmap, even if it's 
not what was requested either:
http://cppcms.com/wikipp/en/page/cppcms_1x_tasks#Implement.Locale.sensitive.Date-
Time.Form.Widgets
"Implement Locale sensitive Date-Time Form Widgets
ICU provides good features for parsing and formatting dates and times, 
implement Date-Time Widget for this purpose."

I was wondering if there's a facility to parse a string into date_time.
Strings such as

YYYY-MM-DD or YY-MM-DD or YYYY-DD-MM or DD/MM/YYYY and so on

Thanks!

Petr
