Re: [Cppcms-users] How to set default response().out() stream precision?

[<ele...@ex...>]

I went ahead and made a patch my self.

File attached. Goes ahead HEAD.

Now doing response().ostream().precision(9) works.

No, the access to out() flushes the headers by design as the data stream
goes after the headers so the headers should be written.

See: http://cppcms.com/cppcms_ref/latest/classcppcms_1_1http_1_1response.html#a39e48c676a3f2c79b26d60b8d455658c

Re: [Cppcms-users] How to set default response().out() stream precision?

[<ele...@ex...>]

Looking at the implementation of http_response::out() it writes out
headers so no wonder set_redirect_header is broken() if I do
out().precision(9).

Would it be possible to expose the ostream without writing headers?

[Cppcms-users] How to set default response().out() stream precision?

[<ele...@ex...>]

Ive tried putting response().out().precision(9) into overloaded
application::init() but that seems to break things.

Whats the proper way?

You can do validation of each widget individually:

http://cppcms.com/cppcms_ref/latest/classcppcms_1_1base__form.html#af7d0a7b4c760b43ea3161181906ee4d0

Look at the JSON-RPC guide on the cppcms wiki.

So I guess you can.

I didnt use regex_field because I wanted the interface of numeric and also
its  low, high etc functions/

regex_field::value() would return a string thats either an int or date. I
didn't think that's a good idea.

I didn't think about deriving from numeric<int>, and overloading load(). I
think that's a better approach than overloading form::load(). Thanks.

[Cppcms-users] Ajax based form validation

[Christian G. <chr...@gm...>]

Hi all,

currently I am looking into a way to integrate client side form validation into
a cppcms application.
I have looked around and found this nice jquery based one:
jQuery-Validation-Engine
https://github.com/posabsolute/jQuery-Validation-Engine

The nice thing is that it provides a nice Ajax api -
https://github.com/posabsolute/jQuery-Validation-Engine#ajax-protocol

Is there some way to reuse the defined validations (e.g. struct
login_form : public cppcms::form) with this api?

thanks

Why wouldn't you use regex_field widget or derive your own widget from the test widget?
It would be more correct approach, you try to change the function of numeric widget
and it is bad idea.

Re: [Cppcms-users] Setting field value after form.load() still fails validation

[<ele...@ex...>]

It's not a default value.

The widget can either write an Int or YYYY-MM-DD in the widget.

my overloaded form.load() uses regex to see if its an Int or Date. If it's
a date, it converts it to an Int based on some rules.

The intention was to convert Date into Int before validation runs. The
field will then be validated as if it's an Int.

I simply had to set num.valid(true) after the conversion to Int.

My main point is that widgets::numeric::load silently validates the form,
when validation should be done when validate() is called.

Re: [Cppcms-users] Setting field value after form.load() still fails validation

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

If this a default value

than

- you should set it before you render the form so it would be seen in the HTML
- you should allow the widget to be empty and check if it is widget_name.set(). If it is 
  not set use default,

Using

  c.form.load(context())
  c.form.num.value(10);
  c.form.validate()

Is not correct. You should either do

  


  if(request()=="POST") {

      c.form.load(context())      c.form.validate()
  }
  else  {
      c.form.num.value(10);
      render("myform",c);
  }

Or
  Do not sent constrains on a num and then



  c.form.load(context())  c.form.validate()

  if(c.form.num.set()) {
     realval = 10;// we got default
  }
  else {
     realval = num.value();
     // do other checks
  }

libc++ is far from being production ready.... It currently
works only on Mac OS X. I tried to compile it on Linux recently
I did enormous tricks to do it. And still got some problems.

Ok... gcc-4.5 had not supported it (it was the last time I checked)
also it seems that gcc-4.6 does supports it. Older version allowed me to compile
the code but the "match result" was always false.

It is good news but I can't relay on it as I support many compilers,
so I'll need to keep PCRE.

Also note... ABI stability - this exactly gives me an ability
to switch the implementation. If I want to I can replace
pcre with std::regex or other engine without affecting ABI!

Anything I need is to replace an opaque class booster::regex::data.

So I can easily remove the dependency on PCRE if the compiler
supports regex.

Actually this may be an action item for next version...

Because booster::regex uses pimpl ideom. The implementation details
are hidden. 

every booster class looks like

  class foo {
  public:
     foo();
     ~foo();
     void bar(baz const &);
  private:
     struct data;
     copy_ptr<data> d;
  };

Where data keeps the actual members, this gives me a great flexibility
to fix bugs or even switch implementation without affecting API or ABI.

This is something can't be done with Boost.

This makes the huge difference between two libraries.

Ohhh please don't talk to me about xpressive. It is SLOW to compile
hard to understand to _AVERAGE_ C++ programmer and what is more
important hard to debug.

Also **nothing** prevents from you to create your own dispatcher...

I don't tell my users how to write the code.

Take a look on the code, and yes, you'll get bad alloc.

So create your own dispatcher... Don't ask an average C++ user to use xpressive.

std::thread does not include two critical parts:

- shared_mutex
- thread local storage support

This is major drawback for me. I uses it intensively. Also booster
has recursive_shared_mutex that neither boost not std provide.

So no I can't switch booster::thread with std::thread

Also boost - by definition can't be ABI stable and in fact is not ABI 
or API stable.

For example boost.locale was broken in trunk for some period due
to API changes.

No, because if I use boost under the hood user will still have
ABI incompatibilities. For example I use some boost code
under hidden cppcms_boost namespace (boost with renamed namespace)
but it is not exposed and I have to use alternative namespace

Even if boost is not in interface you will have ABI problems
if somebody accidentally uses for example boost.1.46.1 instead
of boost.1.46 that cppcms is compiled with...

Also entire point of ABI stability fails.

  http://cppcms.com/files/nightly-build-report.html

And Boost? Boost is not as portable as you may think.

For example boost.thread does not work on SunStudio...
for a loooong time.

Booster is portable if there some problems report
or send patches. In these terms I don't think there is
a big difference between boost and booster +/- some

CppCMS works with gcc>=3.4, MSVC >= 2005 clang >= 2.9
SunStudio >=5.11 and Intel 11

So if you want to tell me that boost is more portable?
I'm not so sure. Most of boost libraries support only
recent compilers, many do not support gcc 3.4

Boost is not self contained and can't be.

Boost.Locale uses ICU
Boost.Iostreams uses zlib.

More than that the 3rd part library detection of Boost is total
crap in comparison to CMake (I know it...)

The only difference between "booster" and "boost" in "cppcms"  context
would be is PCRE and it is not a big deal to compile it
(if it is not already done for you)

And I had problems to upgrade from 1.38 to 1.42 of a small project that
used shared_ptr becuase they broken an interface with auto_ptr.

I had to do version dependent compilation in days back to cppcms - 0 that
used boost to use boost.thread with both 1.33.1 and 1.35

Boost.Locale was broken in Boost trunk (!)
because "header-only" part of boost.thread started requiring
boost.system

I can count much more and it was in 1 minute I thought.

Sorry for the repeat emails, I pressed space key several times without

Question is, is it proper to set a validation flag without to running
form::validate()?

What I have is a numeric<int> widget which can either take an int or a
date. Ive overloaded form::load to calculate days from a given date.

Hi,

Example:

form.load(context());
form.days.value(4);
form.validate();

days is set to validate low(0) but form.validate() still fails as if days
was never set to 4. Is this expected if so why?

I think you do something really wrong. If you really need more than 4 
paramters to handle you really should ask yourself why.
Again, if you really need them, try to avoid it.
You may can do a regex first and then concat and seperate them via an 
sign, like ; (csv) and then assign them.

As I said before. Rethink you design!

What do you mean by previous url? E.g.
example.com -> click on a hyperlink, go to example.com/test and then you 
want the example.com page?
If you have to use this, you should rethink your design.
If you are absolutly sure you need this, you either can do
     http://www.w3.org/Protocols/HTTP/HTRQ_Headers.html#z14
     or define a form in your webpage and set a parameter the previous url.

I guess you are trying to get a coloumn by its name? Try to get it via 
its position instead. As I posted some times ago, never use SELECT * ! 
If you do so, you can define the order of the coloums and get them via 
the position. Also it's faster.
For you problem:
     either make a solution on your own and then commit as a patch
or make a feature request tracker.

[Cppcms-users] dispatcher().assign() and more then e4 parameters

[sergey l. <ccp...@gm...>]

Hello All!

In my application I need more then 4 parameters in dispatcher().assign()
function but there are only 4.
How can I get values of 5, 6, 7 regexp matches in assign function
(controller)?

Thanks in advance.
