Hey guys, how do I get the data from a json object in my view? request.POST['mylist'] doesnt work, and request.POST.get['mylist'] returns None. But when I print (item) for item in request.POST.items(), it gives me the list I want, but the values are off.

https://dpaste.de/TJgm this is the output of print(item)

so I know it's getting the name "mylist"

okay, I used getlist() which works, but it still gives me mylist[2][] instead of the value in the list

themediator: POST is only for form formatted data

you want json.loads(request.body)

if you wanta list of values, use getlist()

why are you using that silly PHP-ish [] naming?

I thought you said JSON

I was just trying some things that I saw in help threads

so, you want to lass multiple values for a single field?

why did you sad about "get data from a JSON object"?

if you have multiple inputs with name="mylist" ... then you get their values as request.POST.getlist('mylist')

request.GET and request.POSt are QueryDicts

No, I'm passing the list through in the data field of the ajax POST

data: { 'mylist':mylist }

mylist is an array

if it showed in request.POST... then you are not doing that

not passing JSON that is

show me how you're passing the data

request.POST is only populated if one of the two form encoding formats is posted

if you're just passing data to $.post or $.ajax... it won't use JSON, AFAIK

Hi all, I'm wondering if this is a good way to setup my model. Basically the user will only ever have ONE of the following types at a time. http://dpaste.com/1SQ0JTT

so my model has a Text field (mainly for HTML), JSON field, and File field

and there will only every be one on the model

ycon_: seems kind of redundant to store the type, unless you need it for performance?

besides, you don't validate your requirements

nkuttler: i thought that might be better to filter the data via the API?

so I can just query via the integer- basically I only want the API returning the data of the field that applies

sure

ok cool thanks.

I'm also trying to return some data in the admin.py

It works in models.py, but it can't find the self (here's the trace http://dpaste.com/08EMQY0)

c

ycon_: you have to use the callable itself afaik

(and you wouldn't usually capitalize method names in python)

whats the callable itself?

list_display = (Test,)

nkuttler: hmm that returns (None)

Is there a way to rerun all migrations from scratch?

I think I messed up some of mine

you can always backup your db and make a new one

reisio, that just gets rid of all the data entries I have made, right? Or users as well?

themediator: you can run your migrations back to "zero" .. but that, too, will lose all your data

I'm fine with losing my data

themediator: everything, in the db

It's all just test data right now

python manage.py migrate zero

I figured

but dropping the db is probably quicker

non-interpreted? :p

says app "zero" does not have migrations

is there more to that command?

Or just instruct me on how to drop the DB

are you using sqlite?

(the default, basically)

i guess so

there's probably a file with a name like 'db.sqlite3' at the top of your project hierarchy

mv it elsewhere

Okay. Do I need to do anything else?

nope

you're back to zero

migrate away

well that didn't fix my issue

cool

what's the issue?

I think I need to try to zero my migrations instead

I don't think that will help if mv'ing the db didn't

:D

ValueError: invalid literal for int() with base 10: 'milk'

sounds like a good old fashioned python error

This comes from me deleting a foreignkey value, forgetting about it, running migrations a few times over time, and then eventually it popping up telling me it needs a value, so I just put in the string 'milk'

heh

Now, something is looking for that value that I put in

and I don't know whyu

I thought it just wrote it into the migrations

yeah, well, just fix it

-.-

why would you be converting the string 'milk' to an int :p

It's not me. It's all on django end

I'm just running migration

sure... but initially it's definitely your code

where's the 'milk' occur?

there is no 'milk' in my code

It's what I input when prompted while running migrations earler

it told me it needed a value for it or something

I figured it would be okay with anything, because I deleted it

okay find the int then

I thought that int was a model object instance

I deleted the db, but not all references to it, apparently

right, the problem is in your code

themediator: where's it ask for the value?

what do you mean?

you said it asked for a valud and you gave it 'milk'

value*

Yeah when I ran migrations earlier it errored out after I deleted a key that I shouldn't have
