Anyone know why django thinks my ImageField is an int? http://www.rafb.me/results/0GYKB693.html

The error itself occurs on line 127

django doesn't think anything

that's easy_thumbnails there

anyways image_set.all.0 is an model instance

Oh wait, I changed it when i was trying to fix it

not a file or thumbnail thinfy

one sec

image is a ImageField, not an int

well sounds like it expect a size of width & height

Ah, I see

it's talking about the 400

thanks

can I add a url to the existing admin namespace, and if so, how?

only via include()

or override get_urls on the AdminSite/ModelAdmin

thanks. Have to rethink this.

how do you guys handle dynamic/interactive content in django?

define “ dynamic/interactive content”

so from current project: there is a table of products, above it there is "add product" button showing modal for this purpose and on clicking row it pops up "edit product" modal

what is dynamic about this?

or more dynamic/interactive than any other site out there

How do I know the user that last modified my model through the Admin Panel?

until recently i didn't know how to handle that dynamic loading/changing stuff in Django, used REST + fully fledged client side frameworks

mribeirodantas: you would have to store that on save yourself.

drag0nius: are you asking how to create a modal?

but recently i saw "newbies" either rendering everything at page load (monstrous templates), then they made it into loading EVERYTHING with AJAX calls

the rendered HTML

tbaxter: But django admin already stores what has been modified, right?

Right when you log in, you can see a table with it

Anyone has any idea about what {{ redirect_to }} does? I can't find anything in the docs about it except this https://docs.djangoproject.com/en/1.7/topics/i1...

i came up with the middle ground: rendering as much on page load, but still in widget-style approach (short templates with <script> tags handling them), then loading whole modals at once in similar way

i want to know how other developers handle those non-static pages

everything i've read so far is either REST focused or doesn't talk about dynamic client-side at all

drag0nius: i make pages that work, then add JS to sweeten to taste

drag0nius: generally I make sure that my pages work without javascript and then add javascript later to make it more dynamic - but then I tend to disable javascript myself so get annoyed when sites don't work without it

so you're more like form-wizards and page-reloading?

i'm adding a bunch of objects to my DB via a standalone script using the ORM. the model i'm adding instances of has a M2M 'sites' to the Site model from the sites framework. I'm passing a dict for creation, e.g. ModelA.objects.create( {valuedict} ), but I'm not sure how to add the (required) site association in this fashion, since I won't be able to create the M2M association until after the ModelA instance

is saved and has a primary id .... what am i missing here?

hackedhead: it will be easiest to help if some code is linked.

Is there a way to assign a default value for a model field to a related model's?

Like say you have model a with a max_transaction field

and then a model b that does too

and you want model b's max_transaction to be equal to the value of your instance of model a

hi, what would be the best way to know to tell if a model has a given fieldname?

let's say I do: from myapp.models import MyModel

I want to know if MyModel has a field name 'my_field'

not talking about objects but the model itself really. I'm not really interested to know that the model class has attributes that are not fields really

just the fields

lduros: how do you not know what fields are on the model?

tbaxter: it's to make a dynamic search by name/field

i see

how about: t = MyModel._meta; t.get_field('my_field')

would this work?

i guess i can try

looks like it would work with a try/except

try: t.get_field('my_field') [do stuff] except: field doesn't have this attribute.

the admin seems to be able to enforce required M2M fields for new objects, but is it just trickery and M2M fields aren't required to save() the model, and added after?
