Using % with psycopg2
Hi,
The following code fails on windows, and works just fine on my unix
box. To fix the problem in windows, I must replace('%', '%%') so its
internal string formatting doesn't fail on me. Should I file this bug
for psycopg2?
from django.db import connection
cursor=connection.cursor()
cursor.execute("select '%';")
print cursor.fetchall()
Thanks,
Sia

Custom Template Tag with {% end... %} tag
Hi,
I can't understand how template tags such as if, for and ifequal
manage to have an accompanying endif, endfor and endifequal, and I
can't have it. Or I can't manage to find out how to do it. So, I
basically want to do something like:
{% customTag %} hello {% endcustomTag %}
and within my customTag implementation, have 'hello' as a parameter.
Thanks for all the help in advance,

How to set SESSION_COOKIE_DOMAIN for multiple Domain Names
Hi, My django app must serve multiple domain names. I also have a need to have my session available on my domain and subdomains. So, reading up on Django docs, I realized I have to do this: SESSION_COOKIE_DOMAIN = '.mysite.com' So, my question is: How do I have my sub-domains share the same cookie with dynamically setting this variable? -- side note: My localhost cannot hold cookies as soon as SESSION_COOKIE_DOMAIN variable is set with a starting dot. Ideally django would take care of it. Not sure if I must file a ticket for it.

Need a Middleware to select urlpatterns
Hi, I need to select different urlpatterns in my middleware's process_request hook. The docs say, process_request is called -before- the appropriate view is selected, which should mean there must be a way for me to tell django to use a different urlpatterns. I checked on CommonMiddleware that does a bit of url-rewriting and found it does a HttpResponsePermenentRedirect and not change the actual url in place which seems odd to me as I expected the middleware to rewrite the URL in place.

Re: How does Django know the PK of the newly created object
Thanks everyone, Once again, I do not expect to know the record's ID before having saved it. But once I save it, that object DOES HAVE an id. I am assuming it was a simple insert command underneath, but do not know how this DB assigned is has become visible to Django. The django code representing how it was done is not easy to understand. To state it simply again: How does django know the PK of the object it just saved, given it is the server that sets the PK?

Re: How does Django know the PK of the newly created object
My examples was faulty. Sorry. I meant after you save the object for the first time, that is: obj = Product(name='Apple') obj.save() At this point obj has an ID in it. How does it know that ID? A SQL statement similar to the following must be generated: insert into product_table (id, name) values(next_sequence, 'Apple'); But that SQL statement doesn't return its generated ID. Is it that Django first gets the next ID in sequence and then uses it in insert or it retrieves it in a different way. As Alex mentioned above, if there is a select statement, what could it be? (Select id from product_table where name='Apple') doesn't seem plausible. Once again, I have an AFTER trigger that sets my PKs from a different table and need to understand how django does it, so I can understand how to approach my own problem, Thanks again, Sia On Sep 23, 5:58 pm, Richard Dahl <[EMAIL PROTECTED]> wrote: > Actually, > from the db-api documentation. > > "To create an object, instantiate it using keyword arguments to the > model class, then call save() to save it to the database. ... > > ...

Need to add Decorator to a many-to-many's Add method

Re: Django, Postgres and Server Crash
Per connection? Does it mean per request, or page view? I tried increasing the number of postgres connections, and it ended up completely killing the server. The server I'm working with has 2 django sites running, one of which receives around 3M hits a month. The other one somewhere around 200K hits, but I do much datawarehousing on the same server using Django API. Django really takes care of closing the connections, so do I have to really worry about that?

Directional Many-to-many
Hello,
Given this model:
class Person(models.Model):
name = models.CharField(maxlength=200)
children = models.ManyToManyField('self')
I can do:
FatherObj.children.add(ChildObj)
Somehow though, if I go to ChildObj and ask for its children, I will
get the FatherObj as well. What am I doing wrong?
In my real example, the childObj can have many parent nodes, thus
many-to-many is required.
Thanks,
Sia

Multiple copies of a Block in my Template
I can think of instances where you would need multiple copies of a
given block. For instance, I am want to show a page counter (Page 1,
(2), 3, 4, 5, 6) both on top and bottom of my page. I had to use the {%
include %} tag twice to load it. Except, I realized I want my template
for both standard view and search result, and that got all too nasty.
So, I think if we could do something like
{% block foo %}
some html
{% endblock %}
{% PasteBlock foo %}
{% PasteBlock foo %}
That would be great.
Thanks,
Sia

Re: New Django manage.py bugs
Thanks for the response adrian. Somehow I felt the result of Alter Table is not as efficient as properly creating the table in the first place. If I'm incorrect, that I think I am, your suggestion is actually very good and should make my life more efficient. I guess if I go with above, I don't have to cry over 'init' again, and thanks for the quick tutorial on install django_apps. In terms of broken pieces. My sqlall worked fine right now, but my sqlclear generates something like this: ...

New Django manage.py bugs
I am 7 months into coding a large django application. Due to needing extra bytea fields with my database, I started maintaining my own SQL instead of django-admin install app. Everytime I made changes to my model, I would take django-admin sqlall app and apply those changes. Its been a few days I've been trying to upgrade my django from 9.1 to 9.2. My biggest problem so far is how broken sqlall and sqlclear are. sqlall generates sql with tables out of order, thus my postgresql cannot create constraints. And sqlclear generates non-working sql. Furthermore, I needed django-admin init that would create initial tables before I manually add my own tables. Please give it back to me. What could make my day would be if there was a way for me to supply an alternate 'sql' for the CREATION of that specific model. It would save me a lot of time not going through my gizilioon tables everytime I made a change.

View Post Processing
Reviewing my own application, I realized there are much my view has to take care of that doesn't need to delay HttpResponse to the user. For instance, I need to - extract the newly uploaded PDF file to extract and index its text. - create PDF docs for new orders - Resize uploaded image, etc All of which do not need the user to wait around for the process. I was thinking to run those processes on a second thread as the view, but I wasn't sure if it's a good practice. So, I was thinking it would be ideal if Django can provide some sort of post processing features either within the same function (instead of returning HttpResponse, you call it) or a secondary function that is called when the view returns.

It seems like a freak problem to me. I spent a long hour to track the

The following statement fails because it has the '%' sign in it.
cursor.execute("select '%'")

How do I address this problem?
Please note that the following work just fine:

Re: Can/Should I place python objects in Django Session?
True, python objects are very useful all by themselves. I think I still can get away with DB objects, by regularly updating them, never using session DB objects for insert/update and even monitoring reads on what value is being used. I have not yet utilized the caching system as I thought it is ideal for write once and read many times news-site type of applications. I don't know how much of my basecamp type application can be cached given that it is an interactive app with random read and writes.

I used to think I can't and it is a bad practice to place objects (non-strings) in django sessions. I just realized I can, but I don't know if it's a good practice. Some feedback in this regard is appreciated, Thanks, Sia --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Bug: On add_object created date is not retireved
Just incase I wasn't clear, in case I don't refresh the object the error indicates that it can't save the object with 'None' for its created date field. That is, when the object was added, its created date field was not populated. Sia --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Bug: On add_object created date is not retireved
Hi, On the following model: class Object(meta.Model): created = meta.DateTimeField(auto_now_add=True) account = meta.ForeignKey(Account) title = meta.CharField(maxlength=200) ... When I do: new_object = account_obj.add_object(title='foo') My new_object.title=='foo' is True, but it's new_object.created date is None. So, if I continue to do: new_object.title='bar' new_object.save() I will recieve an error. I currently do: new_object = objects.get_object(pk=new_object.id) Just to refresh my new_object and be able to save it again if needed.

Re: To Truncate a Word to # of chars
emm.. But wait a sec! How do I call a python function from django
template. I don't think it is allowed, meaning that I'd still have to
write a filter using textwrap:
>>> wrap('siasookhteh', 5)
['siaso', 'okhte', 'h']

Re: To Truncate a Word to # of chars
Thanks David. I did feel there should be a way to do this since it seems common enough.

To Truncate a Word to # of chars
Hi, I noticed there is no filter to truncate a string to a given number of characters as apposed to just words. It can be useful. For instance I am trying to show contact list that includes email addresses, and given that some people have bizarrely long emails, I'd like to limit it to some value. Please let me know if this feature is available, or else I'll find out how to implement it as a filter myself.

How to iterate through form object in template
Hi,
I will be creating my custom manipulator dynamically, so I don't know
what fields I have, and I simply want to iterate through them in my
templates? Doing a simple:
{% for a in form %}
{{ a}}
{% endfor %}
doesn't work...
Any ideas?
Thanks,
Sia

Re: Simple Import Module Question
Thanks for the help. I figured if I place the module out of my myproject directory, I can import it. I'll do that for now until 9.2 comes out.

Simple Import Module Question
Probably simple, but this is a problem I cannot figure out. Under my django project directory I have a folder called 'utility': - myproject - urls.py - settings.py - manage.py - __init__.py - apps - - polls - utility __init__.py utilityfunctions.py When I try to import utilityfunctions.py from my python console using the following command, it works just fine: from myproject.utility.utilityfunctions import * However, once I place this good looking import command inside my myproject/apps/polls/models/polls.py it gives me error (ImportError: No module named utility.utilityfunctions)once I try to import the models in using: from django.models.polls import * What is my problem?

Re: DB.cursor doesn't work properly
Reading up on transaction, I figured I have to commit it, except cursor.commit() gives me this error: Error: serialized connection: cannot commit on this cursor Any ideas?

DB.cursor doesn't work properly
Hi,
Some may call this a feature, I call it a bug:
If I do:
cursor = db.cursor()
cursor.execute("insert into tablename values(5,'somename')")
It will work without giving me an error. Even if I run a select
statement within the same session, it would confirm that that record
was entered. But, my postgresql is not really updated. If I run the
same select statement it would have no recollection of such record what
so ever. As soon as I reset my python session, the data disappears.
What is the problem? Do I have to commit the data? How come there is no
documentation for it?
Thanks,
Sia

Re: Multiple Database & 1 Django
Russ, I see the priorities. I'm going to go ahead with a single db for now, hopefully by the time I launch it the feature is out and I would rework some of the necessary changes. Thanks, Sia
Multiple Database & 1 Django
Hi, I am aware that there is a ticket for it: http://code.djangoproject.com/ticket/1142 I was wondering if the wrapper was small enough that can be squeezed by in version 9.2 or anytime soon as I am in desperate need to use it. Specifically, to separate cheap data from expensive data. Thanks for the great framework, Regards, Sia
Re: Deleting ForeignKey Delets my Object!
Jonathan, Don't be unkind to my schema. I enjoyed your blog though. Sia
Re: Deleting ForeignKey Delets my Object!
Please excuse the lack of applicability for this example. It was meant to serve as an example, apparently not a good one. In my database, I have tons of such relationships. I have a Person model having foreign keys to django authentication user model, to the current branch he resides (a foreignkey to branch), etc. They aren't necessarily meant to represent 1-many relationship, rather, just pointing to another object data. Thanks, Sia
Re: Deleting ForeignKey Delets my Object!
The title should say: deletes, not delets
Re: Upcoming project... 0.91 or svn or magic-removal?
Hey Todd, I am working on a large web app with django and backward incompatibility issues shows up on my nightmares from time to time. I would say start your app with the latest version of SVN and always keep it updated. On every SVN update read backward incompatible changes (http://code.djangoproject.com/wiki/BackwardsIncompatibleChanges), address them on spot and let your application evolve with it. Best of luck, Sia
Deleting ForeignKey Delets my Object!
Hi, I have a model similar to: class Phone(meta.Model): number = meta.CharField(maxlength=50, null=True) class Contact(meta.Model): phone = meta.ForeignKey(Phone, null=True) name = meta.CharField(maxlength=200) After I have data in, I want to be able to delete a contact's phone. As soon as I remove phone, it will automatically delete my contact object too. This would make sense with poll/choice, but not everywhere. What is the magic keyword for me to ask it to stop messing with me. :) contacts.get_list()[0].get_phone().delete() Thanks, Sia
Re: Placing urlpatterns inside view files
Thanks Adrian. My main concern was with speed, and I'm glad that's not the case. Regards, Sia
Placing urlpatterns inside view files
Hi, I have lots of views. So, I separated them into sections. I want to package them together with the views they are associated with. Is it incorrect design decision to place my URLs in the same file as my View? Does it make it any slower? What about my manipulators + views + URL in the same file? Notice that these view files are relatively short, since they represent pieces of the software. I am not a big fan of too many files; it makes the whole show a bit too confusing :) Thanks, Sia "Make everything as simple as possible, but not simpler." -- Albert Einstein
