Re: Model Form Field Ordering

[Alex Koshelev]

The is no public/documented API for reorder fields, but you can do some
trick with SortedDict:

class MyModelForm(forms.ModelForm):
   mySpecialField = forms.ChoiceField(label='Special', choices=(('a','aa')))
   class Meta:
   model = MyModelType

MyModelForm.base_fields.keyOrder = ["mySpecialField"] +
MyModelForm.base_fields.keyOrder[:-1]

Re: Two forms.Form one page: second form will not show any errors

[Gordon]

Form 1 Template (rendered from view):
http://dpaste.com/116827/

Form 2 Template (included in Form 1):
http://dpaste.com/116826/

View Code:
http://dpaste.com/116828/

Form 2 Code:
http://dpaste.com/116829/

Once again, the problem is that Form 2 won't display any errors while
Form 1 will display errors fine.

Thanks,

Re: Required help for Basic Data insertion to the database from a form

[Neeru]

sorry for not tell u in problem detail in detail.

i'm new to this kind of stuff. i havn't done this before.

I will try to figure out a way to explain u.

I tried all the stuff that u have said with example.

anyway thanks.

comming to my problem...

as far this code works fine. there is no error in this.
I able to display the form text fields in the form when i use the
url.
In views.py file,
how can i access the separate field values that have been
submitted from html form file,

and submission is done by the object.save() function is used to save
the table.

when i press submit button, just simple go to index page. nothing is
entered into the table record.

Specifics of your view code and the template you are using to render the
forms might help someone spot what is going wrong.  If they're likely to be
badly wrapped in email, someplace like dpaste.com would be better than
putting them inline in your message.

Two forms.Form one page: second form will not show any errors

[Gordon]

Hello,
I have seperate django forms wrapper in one html form tag in my
template.

When i render, both forms display fully. When I post, errors display
for the first form but not for the second.  I am using a tag by tag
approach to the the template.

Interesting thing is I did a test to see if form2 was bound:
{% if form2.is_bound %} This is bound {% endif %} and it is
It should be displaying errors (I am leaving the fields blank and they
are required)


is it any thing to do with form1 being a ModelForm and form2 is a
Form?  This is my first django app so maybe i missed something when I
declared the Form class.

any suggestions?

I don't know, it is not something I've ever needed.  If you Google
"composite primary keys" and Django you'll get hits that point to the ticket
where the feature is requested and various conversations on the development
list, etc.  Perhaps you can find some useful hints in those sources.

I don't know of any hook/knob to adjust the order of fields.  You may need
to write a custom form renderer rather than relying on the generic
form.as_*.

No, you cannot do this at present.  Composite primary keys may be supported
at some point, but they are not now.

Model Form Field Ordering

[Brian]

I have a ModelForm subclass where I define a special field. How do I
make that special field appear first in the rendered form (using a
form.as_* method)?

Here is an example:

class MyModelForm(forms.ModelForm):
mySpecialField = forms.ChoiceField(label='Special', choices=(('a',
'aa')))
class Meta:
model = MyModelType

The problem is mySpecialField is rendering last, but I wish it to
appear first.

Thank you for your assistance.

max_length implies you are using something post Django 0.96, so you probably
want a __unicode__ method, not a __str__ method.  It'd help also if you
chose a field (or set of fields) to return that actually exists in the
model.

You've not said what goes wrong with what you've got.  You might get better
responses if you put more effort into describing what your problem is,
exactly.

Re: Overriding admin template: index.html

[knight]

My problem is that I want to pass additional variables to index.html.
So I thought I can do it if I add these variables to view that renders
index.html.

Re: Serialization

[issya]

Brian, I can get data on the maps with no problem. It is just making
it change when the user selects something. If you are trying to get
data on a map, I have a handy way for you to do it. This is only for
your template. You will have to find a way to geocode everything ahead
of time. GeoDjango can do this or something like GeoPy can also. There
are also snippets on Django snippets that have different ways doing
it. Sorry if you already know how to do this and I just misunderstood.
This worked for me because I already had the lat and long for what I
was doing.

# In your template do this. The gmap will load in the div with the id
of map.
# You can style the div to be different sizes. You can also get a
smaller map
# control from google.
