FunkyBob: thank you! it seems to work now. how do tell if the login was successful or rejected? it only sends back a template

srnagappan: well, either it sends a 200 to mean you failed, or a 301 to mean you succeeded

that's what an API-specific login is perferable

Any idea why the file being downloaded is corrupt here: https://bpaste.net/show/680028f68fa1 ... I tried to update the answer here to Python 3: https://stackoverflow.com/questions/25364711/

define corrupt? can you put it somewhere?

FunkyBob: how do i get the status code from the promise?

does fetch work differently than promise.resolve(ajax)?

dang`r`us: here it is with the imports https://bpaste.net/show/71dac266b995

i get undefined for response.status

adamsilver, hm, that file is full of numbers. I have an idea ...

yeah, not sure why

srnagappan: yes, yes it's different... since $.ajax is jquery... fetch is a native API

adamsilver, yeah, it looks like something is converting the bytes of your file to a decimal representation. at least it starts with the decimal number 31, which seems to indicate a gzip file when converted to binary

adamsilver, shot in the dark but try passing json_file instead of json_file.getvalue() to StreamingHttpResponse

dang`r`us: same problem but now the file inside is empty

adamsilver, probably need to seek it back to zero before streaming it out

I gotta say though, if you write the whole gzip beforehand anyway, a streaming response seems somewhat weird to me

dang`r`us: now even the outer file is empty

adamsilver, show most current code?

dang`r`us: https://bpaste.net/show/b0d246c76d1f

hello everyone, pop quiz!

is there a way to set attrs to all fields in a form in one fell swoop? Not one by one?

adamsilver, hm ... my io knowledge is a bit rusty. what do you mean with outer file though?

wait ... file inside is empty means you got a working gzip?

let's take it from there.

adamsilver, can you go back one step and send me an empty but valid gzip file (if that's what your code did actually create?)

rainierman: nope.. just iterate over self.fields.items() in form.__init__

dang`r`us: sorry, I meant the .cpgz inside is 0 bytes in size

that works! Thank you FunkyBob

adamsilver, what is a cpgz? and inside _what_?

dang`r`us: I get it when I extract the downloaded file and keep getting a new one when I try to extract it

dang`r`us: I think the problem is here gzip_handler.write(json_string) ... if I leave it like the original code in SO, I get: memoryview: a bytes-like object is required, not 'str'

py3?

adamsilver, yeah to get bytes you must encode

yes

json_string.encode('utf-8')

your_string.encode()

yeah, being explicit about utf-8 is good.

same issue

code and traceback, please?

+FunkyBob: https://bpaste.net/show/71dac266b995 -- no errors

the file is corrupted

adamsilver, anyway, when you implement my first change, you get a working gzip file but its content is bananas/empty, yes? can you upload such a file somewhere please?

what if you use a FileResponse instead?

dang`r`us: the file gets downloaded with my code and after your changes as well but when extracted I get "activities.json.gz.cpgz" and when I click activities.json.gz.cpgz I get another activities.json.gz.cpgz and so one

adamsilver, I still want that file.also - like FunkyBob said and I hinted at earlier, a streaming response is not very useful here, try a FileResponse

or remove the .getvalue() at least

I think ...

also, where did that .cpgz come from? Not from your code snippet I take it

so you explicitly want to send a compressed file... not rely on transport encoding?

+FunkyBob: response = FileResponse(json_file) gives an empty response

good point FunkyBob

adamsilver, the plus is not part of FunkyBob's nickname

it indicates a certain permission status with respect to the channel

Oh ok :)

FunkyBob: all I want is to send the gzipped file to the client without killing the server

I thought StreamingHttpResponse would help with that

it would if oyu had a streaming encoder

adamsilver, if you create a huge blob before streaming it out (.getvalue()) it's not going to do much good

also what FunkyBob said

how huge are we talking here? is this an actual performance bottleneck or a guess?

IME BytesIO etc tend to be either readable or writable... so... HttpResponse(json_file.getvalue()....) is the way to go

dang`r`us: https://www.dropbox.com/s/odtacqbh0cyvpii/activ...

just a guess

that is empty... also not a .cpgz file

i just renamed an app (didnt have anything in my database yet so not worried about that) and renamed everything in settings and what not, but i am getting a ModuleNotFoundError on the apps file in the app i renamed

wreed: did you update the name in the AppConfig ?

wreed, any pyc files or similar around?

error: ModuleNotFoundError: No module named 'profile.apps'; 'profile' is not a package

i updated AppConfig

what are pyc files?

__pycache__?

yes

what did you rename from and to?

renamed from userprofile to just profile

there is a __pycache__ folder in my app

should i delete that file?

wreed, hmm, seems the problem is you didn't rename it properly

yeah i am trying to fix it

i definately renamed my installed apps and the stuff in the apps file

yeah maybe nuke __pycache__ then

there's a command for that I think

hm, not really.

nuked it

wreed, go to your project root and type: find . -regex "\(.*__pycache__.*\|*.py[co]\)" -delete

still the same thing hm

i just used somethig similar

ok

but still the same error

where else could some information be cached?

wreed, check __init__.py

what's in there?

I mean, profile/__init__.py

its blank

as are all my other __init__.py's

odd

is it not supposed to be blank

?

naw, should be fine

https://dpaste.de/34HV full error if it makes a difference

and your directory is called profile?

yes

no idea then.

can you import profile in a manage.py shell ?

I guess it errors out :/

no i cannot do that

ye errors there

remove it from INSTALLED_APPS and try then

ok so when doing that the console starts up fine but when importing it, it says: 'RuntimeError: Model class profile.models.Profile doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.'

expected... what did oyu import?

a model from profile.models

what import line did you type in?

from profile.models import Profile

what happens if you just do "import profile" ?
