Re: error on manipulator fields
I tried the newforms-admin branch - it did not solve the problem. I am now back to revision 7776 of the trunk. I think the problem is in the documentation. It seems like you must add a "get_manipulator_field_objs" method to your customized class. For example, I added: def get_manipulator_field_objs(self): return [oldforms.TextField] You can see examples in django/db/models/fields/__init__.py Chuck --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: error on manipulator fields
nlforms is "from django.contrib.localflavor.nl import forms as
nlforms"
so these are django's own forms.
But now I understand. I hadn't taken notice of the newforms-admin
branch. I noticed admin was using oldforms, but did not know what to
do about it.
I will try newforms-admin branch tonight.
If you don't hear back from me, that'll have worked :D
Thanks,

What is nlforms.NLPhoneNumberField? It sounds like it is a custom
newforms-type form field to go with your model field? But
get_manipulator_field_objs is an oldforms-type thing and isn't going to work
when handed a newforms custom field.
Have you considered trying the newforms-admin branch? There admin will be
using newforms instead of oldforms so you won't have to get the oldforms
stuff working for your custom model field, just newforms.

error on manipulator fields
Hi,

the admin, i get:

Re: How to build manipulator fields in dynamic way?
hi Jaroslaw, I guess you're trying to implement multipage forms. here is the basic ideas: 1. set a 'step' flag in your view function for determine the current step the user is doing 2. use the form manipulator.fields.append(forms.) to dynamically create form's layout base on 'step' 3. while processing to the next step, you could save the form elements' values in two ways as you like: (1) save them in the session/cookie (2) save them by put them into next step form's hidden elements' value 4. in the final step, you do the actual db saving.

How to build manipulator fields in dynamic way?
How to create manipulator fields in more dynamic way? For example I have the form, where only one combobox field is displayed in the begining. After submit, another combobox will be displayed. But its content depends on previous choice... How to do it if I have to define all fields in the constructor? (it is executed only once): class Test(forms.Manipulator): def __init__(self): self.fields = ( forms.SelectField(field_name='first', choices=[(1,1), (2,2)]), forms.SelectField(field_name='second', choices=[what_todo]), ) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

it's an instance, not a class (Python's convention is to use CamelCase
for classes and all_lowers for instances).

use 'disabled="disabled"' (xhtml compatibility)
And : this is not "because field is an instance", this is "because field
is not a string" (hint: *everything* in Python is an instance).

s/'text in the field'/'string generated by the field's __str__() method'/
Sorry if I look overly pedantic, but correct naming is the prerequisite
to correct understanding.
Depends on what you're trying to achieve. If you want to get the text
generated by the field's __str__() method, modify this text, then use
it, you can do something like:
tags = []
for field in manipulator.fields:
tags.append(str(field).replace('id=', 'disabled="disabled" id=')
But this won't impact the field object itself, so further calls to
field.__str__ will be as usual.
Another solution would be to subclass Fields classes and write your own
manipulators, but this would require a lot of (boring) work.
Yet another solution solution (and a far better one IMHO) is to take
advantage of Python's delegation mechanisms and use the decorator
pattern (nb : not tested):
class DisabledField(object):
def __init__(self, field):
self._field = field
def __str__(self):
return str(self._field).replace('id=', 'disabled="disabled" id=')
def __getattr__(self, name):
return getattr(self._field, name)
for id, field in enumerate(manipulator.fields):
manipulator.fields[id] = DisabledField(field)
Then you can use your manipulator as usual.
My 2 cents...

Manipulator fields
In my program I use something like this: # ... for Field in manipulator.fields: #do something print Field . .. # print Field there can print the correct value that is e.g. but because Field is an instance I can not use that in further processing e.g. string.replace(Field ,'id=','disabled id=') Is there any solution to my problem that is how to replace any text in the Field?
