Oh nice! I didn't know you could use SQLFORM if you weren't using a
database, very nice. Sure looks allot nicer by default.
So based on your example I'm doing this...
def roomcreate():
form = SQLFORM.factory(
Field('room_name', requires=IS_NOT_EMPTY()),
Field('attendee_pw',requires=IS_NOT_EMPTY()),
Field('moderator_pw',requires=IS_NOT_EMPTY()),
)
In the view, {{=form}} gives a pretty <table> version of the form.
What is the proper way to loop through and get the name and
formfield? I couldn't figure out how to apply your suggestion of
form['_name']. I know I'm doing something wrong with the syntax but
this is what I have:
{{ for fieldname in form: }}
<li><label>{{=fieldname['_name']}}</label>{{=fieldname}}</li>
{{pass}}
As a end result I want something like this
<li><label>Room Name</label><input class="string" name="room_name"/></
li>
<li><label>Attendee Pw</label><input class="string" name="attendee_pw"/
></li>
<li><label>Moderator Pw</label><input class="string"
name="moderator_pw"/></li>
I saw in the documentation some form.custom stuff (http://web2py.com/
book/default/chapter/07#Custom-forms) which is nice because it allows
me to call name (form.custom.label) and form element
(form.custom.widget). I was able to figure out a way to loop through
it but I seem to be getting some things that aren't part of the form.
Here is what I'm doing now:
{{=form.custom.begin}}
<ul>
{{ for fieldname in form.custom.label: }}
<li><label>{{=form.custom.label[fieldname]}}</label>
{{=form.custom.widget[fieldname]}}</li>
{{pass}}
<li>{{=form.custom.submit}}</li>
</ul>
{{=form.custom.end}}
The above works and gives me a nice form in the format I was expecting
but I get a extra "Id" item and I have no idea where that is coming
from. So I'm wondering if I'm looping through this properly or if
there is a different way I should be doing this. Here is the
resulting HTML from the above:
<form action="" enctype="multipart/form-data" method="post">
<ul>
<li><label>Moderator Pw</label> <input class="string"
id="no_table_moderator_pw" name="moderator_pw" type="text" value="" /
></li>
<li><label>Room Name</label> <input class="string"
id="no_table_room_name" name="room_name" type="text" value="" /></li>
<li><label>Id</label> </li>
<li><label>Attendee Pw</label> <input class="string"
id="no_table_attendee_pw" name="attendee_pw" type="text" value="" /></
li>
<li><input type="submit" value="Submit" /></li>
</ul>
<div class="hidden"><input name="_formkey" type="hidden"
value="8aa047d2-0f5d-43cc-b146-74720ea09f78" /><input name="_formname"
type="hidden" value="no_table_create" /></div></form>
I'm not sure if the first or second example is the better way to go
but it's nice working through the features of web2py. Thanks again
for the help,
-Keith
