@From Massimo:
you can simply use:
<form ...>
instead of
{{=XML(form.custom.begin.replace(....))}}
my solution is:
{{=XML(form.custom.begin.replace('action=""', 'action="people"'))}}
{{=DIV(DIV('Name:',_id='two'),DIV(form.custom.widget.name
,_id='three'),DIV(form.custom.submit,_id='for'),_id='one')}}
{{=form.custom.end}}
maybe this is not the best practice - but after all at the end everything is
HTML source
I get next HTML source with three line in view:
<form action="people" enctype="multipart/form-data" method="post">
<div id="one">
<div id="two">Name:</div>
<div id="three">
<input class="string" id="person_name" name="name" type="text" value=""/>
</div>
<div id="for">
<input type="submit" value="Submit"/>
</div>
</div>
<div class="hidden">
<input name="_next" type="hidden" value="/moje0/default/people"/>
<input name="_formkey" type="hidden"
value="e0b5af7b-0cad-483b-979d-4f8b014e1d3a"/>
<input name="_formname" type="hidden" value="person/None"/>
</div>
</form>
If I use HTML form or mentioned my example result is same.
*But how in HTML form get hidden fields, and **
value="e0b5af7b-0cad-483b-979d-4f8b014e1d3a"** - and this value it is
changed after every form submit?*
I don't know how web2py work, but I can see that is hard coding reduced on
minimum and I get my need very fast.
And after all now it is only 10 (but not more than 14) days how I use
web2py, or how I heard for web2py.
I tray to learn what is happens in web2py when I put some code in controler,
or view, or model, but it take some time to read and tray some example.
And best effect in learning is when you do some examples, and now I do small
examples what I can need later,
My apologies for my questions what sometimes are not ease to understand but
after all I'm beginner at web2py.
