Joerg

I have an error like this

thankyou Joerg

I am read about this link
http://comments.gmane.org/gmane.comp.lib.cppcms.user/1099
it is about discussion about formatting and store date data to the data
base.

I will try your suggestion and read more about booster and filters in
cppcms.

Thanks

time() ?

localtime_r / gmtime_r and strftime.

mktime.

Joerg

Dear All

I want to ask you about how the best way to get current time in timestamp
format?
Second , how to convert timestamp to date readable format?

I have read from blog example like this :

std::tm now = booster::ptime::local_time(booster::ptime::now());

and was used as paramter for sql statetment

st = sql() <<
"INSERT INTO posts(author_id,title,abstract,content,publish,is_open) "
"VALUES(?,?,?,?,?,?)"
<< session().get<int>("id")
<< c.form.title.value()
<< c.form.abstract.value()
<< c.form.content.value()
<< now
<< open_status << cppdb::exec;

can i use time stamp integer value? how to covert std::tm to intenger
timestamp?

Thanks

What do you mean here? What "context"? Using either GET or POST
depending on the method for a parameter is bad design, but something
various web frameworks have made popular.

There is no generic mechanism for multi-level arrays because that's not
a construct by either form of requests. I have no idea what PHP is
doing, some name mangling internally?

Joerg

I think it is no.problem about GET or POST, but why GET method can not be
captured with load(context)?

Sure, the choice of POST/GET/Ajax should be thoughtful, careful and depends on the current task, environment, compatibility, other factors. In most cases your scenario is correct.

Yes, there are specific cases where a POST is useful for idempotent
operations. Most of them disappeared with AJAX. Secure tips like "POST
is more secure than GET" are the reason why we still have so many
extremely bad behaving applications:
(1) Using POST because it isn't cached instead of proper cache control.
(2) Using POST because it doesn't make things appear in the (client)
history.
(3) Using POST to prevent C&P.

None of this is about security. It is all a form of obscurity at best.

The first criterion for GET vs POST should *always* be: does the request
change any state? If the request is issued a second time, does something
break? If the answer is no, it should *normally* be a GET. There are a
few exceptions:

(1) You want to pass a lot of data. In the past, some servers liked to
complain about passing 200 characters by query string.

(2) You have a sensitive query parameter and can't do the query
indirectly via AJAX OR can't trust your deployment to have a sane
logging configuration.

That's about what I can think of after travelling for 12h. If you look
at it carefully, the second point doesn't really fix the problem in any
way. If you want to pass sensitive data around, encrypt it. Not just the
transport, but the individual item as well. Remember, no storing of
unencrypted credit card data as example. It's quite a good policy to do
that as early as possible.

I'm annoyed by such blanket statements, because they almost always lead
to bad design decisions upfront by people that don't completely
understand the ramnifications. Look at all the web shops still around
where you can't just hit the Back button of your browser without getting
annoying warnings about having to resubmit form data, even if you are
just browsing the catalog.

Please don't repeat such nonsense. Both data sets can be easily forged.
Correctly written GET request handlers are secure simply because they do
not change any state. If they do, they are violating the RFCs badly.

They is no further deserialization going on, think of it as a string to
string map. If you need something more complex, it is often easiest to
hook up the JSON parser.

Ok...
Boost.Asio's run() indeed can be called from different threads - a concept used by MW Windows IOCP. But it addsa significant restriction - ANY callback in the loop can be called by ANY thread making programming realnightmare.
It is valid concept used with Windows IOCP but this programming model is not-so-recommended and hard to do in real world.In real world it is much better to keep the workers isolated in different threads.
booster::aio::io_service::run() should be called from one thread only. Additionally it has different semantics - for example
it does not exit as boost::run when no callbacks are given.
I suggest to refer to booster::aio reference documentation.

Or use main event loop (with reference) than do not create a thread and do not start/stop io_service and do not create thread.

 Because MyClass::work() does time consuming job, I prefer to running it in another thread.

What confuses me is the statements:

"Multiple threads may call io_service::run() to set up a pool of threads
from which completion handlers may be invoked."

and

"Asynchronous completion handlers will only be called from threads that

No good practice is use widgets - because widgets do much more than "convinient" palceholders
- They perform some validation that you even usually don't think of (for example make sure that the text is in valid encoding)- They integrate with CSRF facilities for security 
And more...
I suggest go over tutorials

Hi!

You can get raw post data from request (let's assume cppcms::application& app_;) in your application (below).
(see: http://cppcms.com/cppcms_ref/latest/classcppcms_1_1http_1_1request.html)
But it's not seems like a good practice, because CppCMS have built-in forms/widgets classes - see: http://cppcms.com/wikipp/en/page/cppcms_1x_forms
http://cppcms.com/wikipp/en/page/ref_cppcms_forms
AFAIK values are the same, but by using CppCMS classes you have additional compile-time type checking, usefull functional, etc.

virtual void post(content::my_content& c){
 cppcms::http::request& req = app_.request();
 if (req.request_method()=="POST") {
  std::pair<void *,size_t> post_data = req.raw_post_data();
  std::istringstream ss(std::string(reinterpret_cast<char const *>(post_data.first),post_data.second));
  //BOOSTER_LOG(debug,__FUNCTION__) << "raw post data: " << ss.str();

// Get some submitted values  if(!req.post("check").empty()) //get some hidden input value for form with name "check"
  {
    std::string name = req.post("name"); //get value of input with name "name"// Some handler  }
}

Your problem is this
        io_service.set_timer_event(booster::ptime::now(),boost::bind(&MyClass::work,this,_1));
        io_service.run();
 You are using main io_service and calling it's "run()" member function also run is called by cppcms::service  it is wrong and also you try to stop it.
i.e. instead of     booster::aio::io_service &io_service; just put your own booster::aio::io_service io_service and don't use main one (as you are running it in your own thread)and now you can start/stop it.
Or use main event loop (with reference) than do not create a thread and do not start/stop io_service and do not create thread.

You are reading outdated manual for CppCMS 0.0.x - that exist for historical reason.
Start from there: http://cppcms.com/wikipp/en/page/cppcms_1x_forms To create forms dynamically just create it dynamically but not CppCMS 1.0.x forms are non-copyable so you can't create std::vector<cppcms::widgets::checkbox>  - use vector of shared_ptr to widgets or something likethat.

Thanks Kpeo

So, is there no load for context if i use GET method?

The next, some time I use identifier / name of field using query string
&data[x][name]=value

Is it convert to array like PHP post method, or we must loop manually using
request().get("data[x][name]")?

Thank you

Dear All

is there any method from request object to get querystring value?
is it similar with value from form (using load content)?

Thanks
