Advice NOT 4D

[Alexander Heintz]

Hi Folks,

for a little private pet project i would like to develop a little web  
application.
It will run on my linux server so no 4D or A4D.

I will use MySQL as database as it is already installed.

What are your recommendations to use as a script language?

My current choices would be, in that order:

PHP
RUBY on RAILS (though I still have to get it to run on my Suse 10.1  
with PLESK)
PERL
PYTHON
ASP.NET (via mono)

and for the flashy looks I will use one of the more current libraries  
like EXT, this has already been discussed here in length.

I have frequently heard that PHP is a "bad" and "ugly" language, what  
are your thoughts on this? Any personal favorites / recommendations?

TIA

Alex

There are many "bad" and "ugly" programmers, but no such languages.  :)

I like PHP a lot - in terms of pure getting-it-done functionality it's  
extremely good.  For small-medium projects I almost always use it  
(usually with MySQL), unless forced to use something else.  Python is  
definitely a better designed, more consistent, language, but I don't  
have enough experience with any of the major Python web frameworks to  
know how they compare to PHP...

If you have the choice and the time, use Ruby on Rails.

Hello,

After more than one year working without Active4D, we have to add some  
new functionality to some of our existing web pages ...


Before using Batch, we simply issue a query and create a RowSet:

        $rs := RowSet.newFromSelection(->[FORMALITZACIO]; $map)


Now, after reading the docs, I see that I can create a Batch from an  
existing RowSet or from a Selection.

After creating the batch, we need another RowSet with the current  
calues of the batch,

And, in the final page, just loop through this new RowSet.

Is this the correct way ?

Because while I was playing, I'm having some errors, like:


/Macintosh HD/Users/Rai/Desktop/Web BS/Web/0081/list_batch.a4d [main] 19
/Macintosh HD/Users/Rai/Desktop/Web BS/Active4D/Batch.a4l  
batch.newFromSelection 1
/Macintosh HD/Users/Rai/Desktop/Web BS/Active4D/Batch.a4l batch._init 1
if (is a collection($inSize)) | (is an iterator($inSize))
Expecting a numeric expression.





What I'm doing wrong here ?

<%
        import("RowSet")
        import("Batch")
       
        $map := """
        id: [FORMALITZACIO]ID_Formalitzacio;
        oficina:[FORMALITZACIO]OFICINA_ID;
        sol_licitant:[FORMALITZACIO]INTERESSAT_PRAL;
        data_inici:[FORMALITZACIO]DATA_CREACIO;

        ultim_moviment:[FORMALITZACIO]DATA_CREACIO;
        estat:[FORMALITZACIO]Entitat_ID;


        """
        ALL RECORDS([FORMALITZACIO])
        REDUCE SELECTION([FORMALITZACIO];100) // testing purposes
       
        $rs := RowSet.newFromSelection(->[FORMALITZACIO]; $map)



// Make the batch using defaults
$attributes:=""
$batch := Batch.newFromSelection(->[FORMALITZACIO];$attributes) //  
here is where Active4D throughs the error
$batch.setDefaults

...


// Now make the RowSet from the subset of rows in the batch
$rs_batch := RowSet.newFromSelection(->[FORMALITZACIO];  
$map;'$batch{"start"}:$batch{"end"}')
// Setup the link info, make the links
c_text($prev; $batches; $next)
$needBatch := $batch->makePageLinks($prev; $batches; $next;$attributes)
if ($rs->rowCount > 0)
%>

....



I think I'm confused of default attributes for batch ...


thanks for your help,


regards,


raimon fernandez

Looking at the documentation for Batch.newFromSelection, it says the  
second parameter is supposed to be a number which is the batch size.  
Take a look at the documentation again.

ok, I copied this code from page 429 Iterating Through Rows, and I  
thought those $attributes were there only for changing the default  
ones when you create a batch.

I'll change and see ...

thanks,

Hello,


On page 427 I can read:

The makeFuseboxLinks method and its non-Fusebox cousin, makePageLinks,  
allow you to
customize everything necessary to format the page links exactly the  
way you want, so
you should never have to do it yourself.


I can't find the method makePageLinks ...

Even TextMate can't find it searching all the Active4d folder ...


thanks,

raimon

That's a documentation error, it should be makeLinks.

Hello again,


Any reason why I can't use the | as a batch separator ?

Batch.setDefaults(20;20;1;15;"<< previous";"  "+mac to html("|")
+"  ";mac to html("següent")+"  >>";"strong";"bst")

I've tried with & and works.

Also, I can't use any special accented char, like à à ü => següent


And, sometimes we get queries from 1000 rows, as I see, the Batch  
doesn't add the First and Last, so, if the user wants to see the very  
end (or the end), he or she will have to select some batch before  
going to the end.

What I'm trying to do is:

<< First < Previous 4 5 6 7 ... 45 46 47 48 Next > Last >>

I suppose I have to do all bymyself ...


thanks,

raimon

Hello,


What's the limit of a constant in Active4D ?

I'm using this code fine on 4D but Active4D doesn't recognize the  
constant:

QUERY([BS];[BS]status_id=bs iniciats documentacio penden)


It's 31 char length, if I use other shorter constants works.

Maybe it's a Bug in ACtive 4D when using 31 len constants ?


thanks,

Hello again,


I'm getting an erroneous encoding when Active4D writes some text,  
using <%= %>

All the characters that are outside Active4D tags are viewd correctly.

What I see is that my pages are all UTF-8, and no matter if I use Mac  
to Html or something, the results are always wrong.

The Active4D default encoding is A4D Encoding HTML (8) : A synonym for  
A4D Encoding Extended. This is the default.  and I get the 8 when  
printing <%= get output encoding%>


Doing more experiments, if I change the encoding of my files to Mac  
Roman, Active4D displays correctly, but my normal text appears wrong,  
but if I adjust the html header into MacRoman   <meta http-
equiv="content-type" content="text/html;charset=MacRoman" /> all the  
text is ok.

So, before I re-encode all my pages from UTF-8 into MacRoman, there's  
a special encoding tag for Active4D to encoding from UTF-8 ?


thanks,


raimon

4D 2003/2004 does not have support for UTF-8, so Active4D does not  
either. If you look in the mailing list archive, there was a thread  
about a month ago about dealing with UTF-8 that might help.

It looks like a bug, if it is I'll fix it soon.

Hello

I created a plugin to convert utf 8 to mac and mac to utf 8. (only  
for os x)

After a lot's of tests, I think there is a mistake in Active4d.
When sending Ajax-Request with prototype it sends the data escaped.  
You can see this, when install HttpFox to Firefox.

But now I have problems with the ü (ü)
it is send from the browser as %C3BC which is correct.
But Active 4d convert this Post-Variable automatic and after this  
the "ü" is not converted correct.
In my test I simulate this converting-procedure.
I don't know if it is a mistake in my brain, ore a mistake in Active4d.

you can try out:
http://www.mountain.ch/test/ajaxtest.gos?test=%C3%A4%C3%B6%C3%BC

or try this.

Hello

Now I found a way, to use Ajax with prototype.js but without the  
utf-8 problems under 4D and Active4D.
I don't send the form variables direct, which would create utf-8.
I use the postBody Option, and generate a escaped string from the  
form with the function getMyBody().
This creates a request, which is easy to handle with Active4D ore 4D.
