[web2py] Re: Confused about hidden fields
I am not certain that the case is the same but one thing I noticed
with SQLFORM.factory and hidden fields was that in order to pass a
hidden field from the SQLFORM.factory(...hidden=dict(Sir Robin: 'the
brave')) required that a Field(...) be defined for it in the form
definition.
To make it hidden, just set readable=False, writable=False. So what I
did was something like this:
SQLFORM.factory(Field(...), Field(...), Field('sirRobin',
readable=False, writable=False...),
hidden=dict(sirRobin: 'the brave')
This will create a hidden field that isn't shown or which you can
change and its value is passed in from the controller.
You're already using a custom form and that's important too as the
hidden field must be somewhere in your custom form so that it can
submit your hidden field along with the rest of the form.
I hope this is helpful to you Omi.

[web2py] Re: Confused about hidden fields
On second thought it is not broken. request.vars are processed during form.accepts and form.vars will contain validated values afterwards. Since in this case field2 is not in request.vars, form.vars.field2 will be set to None. To set the value of field2, without it coming in thru request.vars (i.e. field2 is not in the form), one should use onvalidation to change it after it has been validated and before it is written out to the DB.

[web2py] Re: Confused about hidden fields
Thanks everyone.
I'm easy person so I use the CSS to hide it just like JmixIII
mentioned.
something like this.
View
jQuery(function(){
jQuery('.hidden').hide();
};
{{extend 'layout.html'}}
{{=form.custom.begin}}
Field1: {{=form.custom.widget.field1}}
Field2: {{=form.custom.widget.field1}}
{{=form.custom.submit}}
{{=form.custom.end}}

This should work to pre-populate the value of field2 with 'BBB' but it
seems to be broken in 1.99.2

this has no effect, field2 will not be set to 'CCC' in the DB, the
insert has already been done at this point so field2 will be 'BBB' (if
it wasn't broken).
To change it you have to use onvalidation, see the example in the
book.

[web2py] Re: Confused about hidden fields
Instead of form.accepts() you can use form.validate() and then do your
own update. Then you do not need to pass unnecessary variables to the
view and back again.
form = SQLFORM(table, id)
if form.validate():
form.vars.mysecretvariable="whatever I want"
if not form.errors:
if not id:
id=table.insert(**dict(form.vars))
session.flash = "record inserted"
elif form.vars.get('delete_this_record',False):
db(table.id==id).delete()
session.flash = "record deleted"
else:
table[id].update_record(**dict(form.vars))
session.flash = "record updated"

[web2py] Re: Confused about hidden fields
Thank you for understanding me :)
I tried but this code will set the default value if the field exist on
the view.
I made a simple example. I don't want to show field2 so it's excluded
in view using custom form but want to store the value like 'BBB' or
'CCC' before it's inserted into table. This code just leave field2
blank...
model
db.define_table('mytable',
Field('field1'),
Field('field2'))
controller
def index():
form = SQLFORM(db.mytable)
form.vars.field2 = 'BBB'
if form.process().accepted:
form.vars.field2 = 'CCC'
session.flash = 'form accepted'
redirect(URL('index'))
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
view
{{extend 'layout.html'}}
{{=form.custom.begin}}
Field1: {{=form.custom.widget.field1}}
{{=form.custom.submit}}
{{=form.custom.end}}

[web2py] Re: Confused about hidden fields
I believe in your controller, before form.process() (or form.accepts), include: form.vars.FFTSCD = 'aaa'
