don't dump it to JSON? If you want to send/return JSON, it's fine as is.

hah it works now :)

not sure I follow :(

Is there a way to specify only the order of fields in the form?

yes. output them in the order you want them :p

kezabelle: do you mean not to use json.dumps? how do I then apply the encoder?

"If you want to send/return JSON, it's fine as is."

setre: are you starting with a Python object, or a string from somewhere?

when i edit a django template in vim, all of the '%}' closing bits are highlighted in red as if they are syntax errors. What's the best Django set up for vim? I've tried https://github.com/vim-scripts/django.vim and https://github.com/tweekmonster/django-plus.vim, and the problem persists

FunkyBob: a list of python objects

setre: and you want to serialise that to JSON ?

yap

json.dumps(the_data_object)

does the job quite nicely

setre: is this, perhaps, going throug hthe template engine somewhere?

how, exactly, are you passing this JSON blob to the calendar widget?

I think maybe although I have valid json the problem may be that fullcalendar.js doesn't accept it as such

lemme see

I don't think the template engine is involved

how, exactly, are you passing this JSON blob to the calendar widget?

this is my view:

def simple_cal_view(request):

context = {}

return render(request, 'cal.html', context)

so yeah

no wait

I use return JsonResponse(data, safe=False)

ok

and data = json.dumps(list(events), cls=LazyEncoder)

nedbat: i think i use standard html syntax highlighting. all tags are one colour, but oh well

where did LazyEncoder come from/

and how is the browser requesting and parsing this?

the script fullcalendar is requesting it via ajax I guess

no complaints in the console

hop: if you use filetype=htmldjango, do you get the right coloring for django pieces?

What would be an easy way to add checkboxes to a table, and then use it for some actions (like in the Admin pages) ?

setre: you're double-encoding your json. Use json.dumps() or JsonResponse, not both

nedbat: i'm checking right this moment, sec

knbk: ahh thanks

I get an error having this: https://dpaste.de/8Jy0

I'm completely lost how translations work under the hood... does this make any sense: https://dpaste.de/qSXN

Variable annotation cannot be combined with tuple unpacking

nedbat: same thing

It seems to work if function is defined in models.py, but not on import

hop: as me? Red for %} ?

nedbat: no, sorry, once color for the tags

nedbat: ah, the difference is different colors for comments and stuff

hop: i think my problem is due to some other html thingy i have installed....

ovalseven8: you need to create a dict and unpack it: https://dpaste.de/T52E

nedbat: `:scriptnames` and a fine tooth comb...

knbk, Thank you! Why does it work here, however? https://stackoverflow.com/a/4723261

hop: yes, thanks

ovalseven8: that's not what you were doing

ovalseven8: because you're not giving it a dict of kwargs

had you done, .get(**{...}) it'd work

kezabelle, But this is also not a dict here? https://stackoverflow.com/a/4723261

what you gave it doesn't even resolve to args I don't think, hence your exception

no, it's a list of keyword arguments

("kwargs")

Hello everyone. I have a field in my model using CharField with choices. When I want to print the field I got ('U', 'Draft'). How to print only the draft?

In django template.

.get_<fieldname>_display

kezabelle, You mean my bug is that it's returning a string?

ovalseven8: .get(is_active=False) would work fine, but you can't do the same when the keyword is a variable. `'is_active': False` is syntax you'd use in a dict literal, which is exactly what I showed in the new code

kezabelle: I already try get_status_display but it still print the whole tupple.

baguzzzaji, you doing something wrong then

then I suspect you've saved that into the database?

forgot to save, reload or that ^

I use ModelForm to save the data.

or your choices is malformed, maybe?

open a repl/shell, fetch the object from the db, and call .get_status_display() on the instance. And then dpaste that + models

This is the line in my model: status = models.CharField(max_length=1, choices=STATUS, default=STATUS[0])

hop: how are you on this fine friday

knbk, So the packing and unpacking using a dict is actually a workaround to be able to resolve variables?

ovalseven8: yes

baguzzzaji, looks wrong

your default should be STATUS[0][0] I suspect

so yeah, I think it's wrong, and you've possibly persisted the whole tuple as a string to the DB at worst.

hop: found it: watch out for https://github.com/luochen1990/rainbow :)

kezabelle: It should be STATUS[0][0]. I've tried it and its working. Thank you.

np

nedbat: rainbow is that nested-parens thing, right?

hop: yes.

nedbat: always gave me visions ;)

Another question. If I have Chapters with foreign key to a Novel. Is there a way to count how many chapters a Novel have directly with django query method?

wouldnt .count() do that?

all().count()

^ that, unless you want to do it en-masse, which would be Novel.objects.annotate(chapter_count=Count('chapter')) or some variation thereof I think.

lxer: not from view but from template.

if i have a CSV download thats going to take awhile whats a good archectual approach

fission6: you're generating the CSV in Django?

ya, again open to many approaches

So, I run Novel.objects.all(). I want to print how many chapters a novel have directly in the template inside forloop.

baguzzzaji: not sure but I think that would also work , but without '()'

fission6: well, as a generator it can be quite efficient... but the stdlib CSV module isn't very generator friendly

it would.

fission6: define "a while"?

2 minutes

fission6: oh.... background worker queue

if its a "short while" then streaminghttpresponse + generators would do it (with a bit of legwork), otherwise, farm it off to a queue and check for a result

OK

thanks! where woud you "hold" the csv

could a simple model work with filefield and status

My user consists of email + password. Also, users have to confirm their email address to activate the account. Do you think it makes sense to also let them write their password in the "email-activation-view"? I fear that some email providers etc. could automatically check every link in an email and so activate the account (for example because of spam detection)?

depends how big it is.

What's your experience/recommendation?

if its small but expensive to calculate? meh just send back the string as the result :p

ovalseven8: well

ovalseven8: http://musings.tinbrain.net/blog/2018/aug/14/dj...

sleep time for me

GinFuyou: Can you explain why the ProductDisplay is not a good idea and help with an example of a better way, I am new to django so please bear with me?

any thumbs up for using flower or something similar to monitor celery

asej, my bear and balalaika is always with those ready to listen ^_~*

fission6: it's alright

basically I don't think you need it. You now has 3 views and it can be achieved with 2 or even 1 I believe. depends on exact case ofc

is it worth having at all

nkuttler

simple to install, has a decent interface

ok so pretty harmless

just a "nice" to have

e.g. there no problem usin UpdateView as a DetailView, they both deal with single object

yup. we have built our custom logging system, simply to have everything unified

we are switching queing services so thought it would be helpful to. have in place just to sanity check workers and such

nkuttler swapping from rabbitmq to redis in production should be pretty painless? not sure if you have experience with such concepts

asej, as for posting 2 forms, I suggest you go over methods show in url I gave and write analogy code but for form1, form2
