Message-ID: <CAEid6wHywMWAKOr3s_EEF0LjcVtCd5zV-r-EU8nRjp66ymqW2Q@mail.gmail.com>

Hi,
I am using Django mptt library for tree traversal of mysql data and i am
trying to modify the data before i display it in template. Actually in my
mysql rows i am inserting few comma separated user ids but i want them to
change this part of tree and replace them with the user name.
I tried to fetch the tree and loop through it and get corresponding user
ids from database and again assigned them to the variable. When i tried to
print them on console it was working fine but in template it's showing the
database values. If someone could help me to solve it?
Thanks in advance

This description makes little sense, at least not to me.
Please ask a more specific question, and show us
some code.

Ok,
Let me put it in this way:
1 - My table "works" has a column "invities", and this column stores
user_id1,user_id2 type of data. Which means these users are the member for
this particular row data.
2 -  And following code is used to view the tree::
def view(request, id):
    try:
        ideas = Works.objects.filter(tree_id=id).filter(is_deleted=False)
        # Following Code is to fetch user details and replace their ids
with name
        for i in range(len(ideas)):
            invities = ''
            members = ideas[i].invities
            members = members.split(',')
            for member in members:
                try:
                    member_detail = User.objects.get(email = member)
                    member_name = member_detail.full_name
                except User.DoesNotExist:
                    member_name = member
                invities = invities + member_name + ','

            ideas[i].invities = invities


    except Idea.DoesNotExist:
        raise Http404
    return render_to_response(
        'idea/view.html',
        {'nodes': ideas},
        context_instance=RequestContext(request)
            )

3 - The problem in this code is, when i display idea.invities here, it
works fine but in templates it doesn't show the names but email ids.
4 - Following is the code in template:


{% load mptt_tags %}
{% recursetree nodes %}
    Member(s): {{node.invities}}
    {% if not node.is_leaf_node %}
        <div class="children">
            {{ children }}
        </div>

    {% endif %}
{% endrecursetree %}


Now here i want those name to be displayed.

I do not see how this can possibly be working for you,
Presumably User is the django.contrib.auth User model,
in which case it has no attribute full_name (you probably
meant get_full_name()). Thus, an AttributeError should
be raised, and your program should crash.

I suspect that you have not shown us the real code, and
you are instead catching all exceptions, which would
explain the behaviour that you are seeing, as your exception
handling code then simply replaces the original value.

Gora

No no, it's not like that.
I am not using django auth system at all. I had developed my own auth
system because i was not able to find out any easy way to deal with django
auth for my requirements. If you wish, i can show you auth system code also
but here i don't think it's required so i have posted view part only. So i
would suggest don't go that side because it's a different section.

Been a while since I have had reason to play
with SQLAlchemy, but surely this is explained
in http://docs.sqlalchemy.org/en/rel_0_8/orm/relationships.html

If using expression api, it is,

Column(Column_name, None, Foreignkey('reference_table.primary_key_column',
onupdate='CASCADE', ondelete='CASCADE'))

Chandrakant , Well that as I have described in the question did not work .
However explicitly declaring a Relation did . So currently I am going for
that but I just think that should have happened implicitly

No idea, how the orm works, i only use sqlalchemy expression api, that is
enough abstraction i need on top of sql. But from past, i remember that you
need to add reference to the related table.

[...]

To start with, when replying to a digest, at least
trim the unwanted verbiage, and change the subject
to a meaningful one.

A mailing list is not the right forum for basic
learning issues. Please take a look at the many
Python tutorials/books available online: Personally,
I like "Dive into Python", or maybe even take
a short course. Then, you can ask more specific
questions that people on the list can help you
with.

Regards,
Gora
