It

It's not even trying to grab the file

I want to give my frontend a list of img links/srcs. the goal is to make the front end as smooth as a web-app. I plan on having those images preloaded everytime a certain action is performed (like turning on a set of list view filters). Whats the best way to achieve this type of thing?

On a normal 404 django doesn't try to get the 404.html page ether

it would normally look for a 404.html

It just doesn't require one anymore.

hi i would like to ask.. I've created loop database data on production server and one page cannot be loaded because of memory error.. I would like to ask what can happen when I delete one item of this loop? If I remove item in the database it should fix the problem but I am not sure what happen what can occur in python/django thankou

FunkyBob: ya, I looked in the chromium debug network and it doesn't send one. But I have one in my template directory.

FunkyBob: oh wait, sorry...there was a templating issue in it

destnicek: that's rather vague

destnicek: are we to guess you have a model with a foreign key to self?

FunkyBob, the structure is many2many for user groups which should be a tree but accidentally its a loop now

just asking this once more before i go make an SO post: i'm wondering how to go about doing this admin inline thing: http://dpaste.com/1802232/

I have some query set with Comment objects, how can I make it so out of my potentially hundreds of COmment objects.. I only want objects that has a unique attribute/instance variable in the comment model, foobar

destnicek: m2m for a tree? how unusual...

destnicek: so... what are you worried about?

unstable: mycomments.filter(myattribute=whatever)

FunkyBob, what happen if i delete one item which is reference to another one via m2m table in django..

delete the item? or the m2m reference?

FunkyBob, does it trigger the database command which remove all cascading fields or python try to find all child ones and them by one?

cjwelborn: So there might be 20 comment objects, all with the same foobar instance variable. so foobar links to the same object on all 20 comment objects. I want to find the 1/20 comment objects that has the latest 'created' attribute date, out of the 20, and get rid of the rest in the filter.

FunkyBob, i would like to delete item..

Comment.objects.select_related('goal').filter(deleted=False, author=F('goal__owner'), created__gt=F('goal__updated')).iterator()

This is what I have so far.. but I want uniqueness in the comment objects, so comment.goal is unique.. and it picks the comment.created that is the most in the future, for each comment.goal that is the same.

unstable: maybe use .latest('created_gt') (like: Comment.objects.filter(...).latest('created__gt')

or latest('created') .. i think

cjwelborn: That only returns me one object if I do that.

unstable: sorry, i'm misunderstanding the question..

So I have say 200 comment objects, but some of the comment objects have the same goal attribute object, say "goala", so 5 of the comment objects have comment.goal = "goala", I want to take the 1/5 comment objects, where comment.created is the latest.

So that would make it 196 comments, instead of 200

but the .latest('created') give me 1

oh, you want to remove the latest comments from that queryset, and keep the rest?

If any of the queryset has an attribute 'goal' that is non-unique, I want to make the queryset have uniqueness with the 'goal' attribute. The way I decide what to pick, is the comment with the latest 'created' attribute should be kept, the rest I don't want in the queryset.

sorry if my language/communication is confusing, my English isn't good.

I think I understand what you are saying now, but I personally don't know of a quick django chained function to do that. I personally would have to move the operation in to a for-loop after getting the initial queryset. (and then remove the non-unique comments, keeping only the latest comment)

So there might be multiple non-unique goals, so 5 comments might have comment.goal = "goala", another 8 comment objects might ahve comment.goal = "goalb", etc. So I would pick 1/5 and 1/6 that have the latest comment.created time

: i have a form with two submit buttons, but on click on the second submit button, i'd like to skip validation of certain fields, is this possible?

joelones: isn't the value attribute of the submit button passed along? then you could decide what to valuate

validate..

nkuttler: yes i do know what button is pressed and how to test for it, but how exactly do you validate certain fields?

joelones: depends on your code i guess

joelones: just in case you haven't yet, check https://docs.djangoproject.com/en/1.6/ref/forms...

thx

I'm getting a 'DataError' 'integer out of range' on a django model I'm making, even using the admin interface. So, I believe there's an issue with the table structure (using Postgres). Anyone know a way to nuke a table and remake it?

^ without nuking the entire app...

mattmcc: when using urlencode, it only gives whats already in the url. Is there a way to convert GET params to the url? Like displaying POST input's in the url

ah wait.. hmm… it should work
