mattmcc: when i try to migrate the updated model, i get "'DatabaseOperations' object has no attribute 'geo_db_type'", any idea what that is?

Oh, you need to change your DB backend.

And there's some DB setup that's needed for the geographic functions to work. https://docs.djangoproject.com/en/1.8/ref/contr...

mattmcc: is this definitely the method you'd recommend to get this geo functionality working?

sudomarize: Yeah, using real geographic fields instead of doing the math by hand with plain lat/lon fields performs much better.

mattmcc: ok great. i guess i need to use postgis (postgresql is my db)?

Yeah.

mattmcc: this shouldn't really slow down my application should it? Got this irrational fear that it might do some damage to my apps performance

No, postgis is simply a collection of functions and data types.

mattmcc: is there a guide that has a list of all dependencies? i keep getting things like 'libxml2 config not found' (fixed), gdal-config not found

From the broader install notes, https://docs.djangoproject.com/en/1.8/ref/contr...

don't know if anyone has seen this but these are the results of the django community survey https://docs.google.com/forms/d/1Owv-Y_beohyCm9...

pretty interesting data

WeiJunLi: Note that the exception reports the arguments it tried, and pk is an empty string.

I am trying to set form widget with CreateView and ModelForms, have set widget in Meta class of ModelForms class but it is not working

mattmcc: so it means there's something wrong with the queryset maybe?

can anyone give some solution

WeiJunLi: Given your template, it just means checkout_id didn't have a value in it.

mattmcc: at that point pk shouldn't retrieve an empty string :\

mattmcc: what you suggest to do?

WeiJunLi: Well, what is checkout_id supposed to be? Your view doesn't appear to be setting it in the context.

is it possible to give a short_description to a modeladmin action?

voodoo-burger: Yep, just set their short_description attribute. https://docs.djangoproject.com/en/1.8/ref/contr...

but i have to do it outside and after the def of the action in question right?

actions = ['approve']

def approve(self, request, queryset):

rows_updated = queryset.update(approved=True, date_approved=datetime.datetime.now())

if rows_updated == 1:

message_bit = "1 comment was"

else:

message_bit = "%s comments were" % rows_updated

self.message_user(request, "%s successfully approved." % message_bit)

approve.short_description = 'Approve selected comments'

oops, guess that doesnt work

mattmcc I'll just handle that later, just removed that part for now cuz the logic stuff isnt working properly, can you take a look into this other problem? https://dpaste.de/KizO

When you override request methods like get, post, etc, you still need to retain their ability to accept arbitrary keyword arguments, like pk.

Since it's one of the named groups in your urlpattern.

mattmcc: oh alright added *args,**kw

The view app.views.CheckOutView didn't return an HttpResponse object. It returned None instead.

should I use render_to_response instead of render?

To keep with the UpdateView workflow, on a valid post you should return a redirect. Normally UpdateView would return self.form_valid(form)

mattmcc: where is that info? I can't find in the docs, also in the docs I only see 2 things about UpdateView

voodoo-burger: this should work

mattmcc: seems it isn't related to the way I am rendering it, traceback here https://bpaste.net/show/f3a65097ee8c

I can load css and js files but the images in the line 135, 141 and 147 are not rendered. However, if I go to the url, i can see the images. Does somebody know why this is not working? http://hastebin.com/ogujedelur.django

WeiJunLi: You're not returning anything if the form is invalid.

metaljack34: Is the path correct ?

It'd probably be easiest to just call up to the parent method with super()

Nux17: Yeah, this works. http://localhost:8000/static/img/slide_one.png

metaljack34: What does "manage.py findstatic img/slide_one.png" say?

mattmcc: if form.is_valid() ?

mattmcc: Found 'img/slide_one.png' here: ~/prj/static/img/slide_one.png

WeiJunLi: Yep, this is how you can tell a form is valid or not

metaljack34: Okay, so it's probably not a Django issue.

You're not seeing 404s in Firebug or other inspector tools, are you?

mattmcc: Nope, I can actually see the thumbnail of the image if I hover the link in the firebug

So, yeah, it'd be a CSS thing.

Should be a CSS issue then

Maybe the divs just aren't big enough to see the image.

Or Bootstrap is doing something strange.

mattmcc: I've added def form_valid(self, form): super(CheckOutView, self).form_valid(form) but I keep receiving the same errr

WeiJunLi: It's saying you're not returning a response if the form is _not_ valid.

mattmcc: I see. The plain html template actually works. Anyway, I'm gonna play with the html. Thanks

mattmcc: can you be more specific?

mattmcc: I think it is pretty clear, if form.is_valid() return the render success_url otherwise form = form_class

if I have a post() why would be necessary a form_valid(), don't get it.

because in post it verify if the form is valid or not :\

WeiJunLi: in a CBGV? because it's a hook point for you to decide what happens when the form is deemed valid

any idea why manage.py migrate wouldn’t be detecting migration files? i’m trying to load fixture data and it tells me a column doesn’t exist…yet it exists in the models.py file and in a specific migration file.

FunkyBob: so would def form_valid(self, form): return super(CheckOutView, self).form_valid(form) be enough ?

mattmcc said it isn't returning a response if the for is _not_ valid and I'm not sure what he did mean by that

SteenJobs: happened to me, finished setting the column manually through my SQL admin

WeiJunLi: if that's all it did, you wouldn't need to override it

what do you want to happen when the form is valid?

I haven't seen any of your code, yet, so...

Nux17: it would involve a lot of manual work though…i presume if this column doesn’t exist then there are a bunch i’d have to create in postgres from scratch, so ideally i’d like to get manage.py migrate to work...

mattmcc, i'm getting "Cannot use object with type float for a geometry lookup parameter." when trying to run migrate after setting up postgis. Any ideas as to what could be the problem?

sudomarize: you've passed a float for use in a geometry lookup
