avafab: did you read the tutorial?

+ the template docs?

apollo13 could you please address me where to find more informations?

parin: You can simplejson.dump a list

avafab: https://docs.djangoproject.com/en/dev/topics/te...

tnx

shredding: i am reading the documentation of simplejson, and yes, it is better than serialization. Thanks for your help :)

apollo13: the token is in the cookies, but the ajaxBeforeSend doesn't seem to work. The ajax POST doesn't send a modified header with the token

spirat: then use the debugger to step through the code

parin: you may find django-tastypie or django rest framework useful

hey all, I want to create a form for a model. One attribute within this model is foreign key to another model. I want to allow users to create the foreign model within the form - sort of a subform. I have goggled and checked djangopackages but cannot see anything to help. Can anyone please guide me in the right direction?

apollo13: which code? The $.ajax() one?

spirat: I'd set a breakpoint in the first line of ajaxSetup

a13x15: thanks ! I don't know about REST protocol. Please can you give some links for learning it ?

apollo13: which is where? I'm afraid you're talking about a function that I don't call directly and is in the jquery.js file (which is unreadable as it is)

spirat: no, you did write an ajaxSetup function I assume

spirat: ah, the beforeSend callback

apollo13: Alright, my bad.. I was focused on BeforeSend

yeah, first line of that

also: Due to a bug introduced in jQuery 1.5, the example above will not work correctly on that version. Make sure you are running at least jQuery 1.5.1.

Yeah I just download JQuery yesterday, should be fine :)

downloaded*

ah I think I get the problem...

I should do a setup everytime I do an ajax request right?

parin: you can take a look at the entry in the wikipedia for a quick introduction

spirat: no, you just need to call that function once, jquery will then automatically call beforesend for every ajax call

ineedarobot: inline formsets are probably what you want and are part of Django => https://docs.djangoproject.com/en/1.5/topics/fo...

parin: in short django-tastypie makes easy to create an API that can be used from the client with ajax to access/manage your data

I Has anyone successfully implemented nested formsets ?

nested forms are somewhat ugly but doable

apollo13: do you have any urls that could help please?

a13x15: okay

nope, closed source projects ;)

apollo13: lol, fair enough

apollo13: I am going to look at implementing this and will share it once completed. I wanted to check I was not implementing something already in core django or something readily available

apollo13: yeah, well the problem is that when the page is loaded the ajaxSetup is called: http://bpaste.net/show/87815/ and at that point it doesn't enter the condition. If I copy paste that code jsute above the $.ajax, it works

ineedarobot: did you look at inline formsets?

spirat: which condition?

nkryptic: yes, but i now need nested inline formsets

apollo13: The one for the request type

spirat: during pageload ajaxSetup is called, you won't run into beforeSend at that point

apollo13: I thought it was like a callback that was called for each ajax call

it is

apollo13: then how come it works when I do it just above the ajax method? Should it be in the same <script> block?

nkryptic: I see the inlineformset_factory function has a form set param but I cannot find any docs on it.

spirat: shouldn't matter

apollo13: that file is included at runtime with <script src...>, can it be related to the problem?

no

strange then... the setup failed the first time, I assume.

ineedarobot: I think it's old, but still pretty clear: http://charlesleifer.com/blog/djangos-inlinefor...

good mostly-morning

nkryptic: thank you for the link. I have checked through it and it does not seem to handle nested objects. for example if the RecipeIngredient had 'manufacturer = models.ForeignKey(Manufactorer)'

I think I can fudge it for my specific purpose as my top level model is sort of a through table (conceptually)

i have a situation where a template is complaining because it's not getting the right data…i've instrumented the thing that's supposed to give it the data, but it's not being called…i'm not sure how to proceed

klrmn: You could explain the problem more, give us some code/tracebacks...

ineedarobot: I don't see how you could edit that on the same page - recipe form + multiple ingredients forms and each ingredient has a manufacturer form? what are your specific models/relationships?

nkryptic: use case for that example would be "a user wants to add an ingredient to a reciepe but it does not exist yet and would like to add it inline - but the problem is the manufacturer of the ingredient does not exist either

gcbirzan: here's a traceback https://gist.github.com/klrmn/5277841

well it want's a float, what is val at that point?

hey, I am trying to write a template tag that adds a value to the current context eg: {% order_total as order_total %} ... {{ order_total|somefilter }}, should I be using assignment tag? there is no format_string to pass in so not sure

gcbirzan, apollo13: it's being passed an empty string. here's the code that is supposed to be feeding it values but isn't being called https://github.com/klrmn/moztrap/blob/suite_res...

klrmn: well then go up the stack to the point where completion gets called (or rather should get)

epicowl: yes, use assignment tag. then your function would just not accept any arguments... def order_total(): return utils.get_order_total()

nkryptic: is there a way to make it work w/o passing a format_string? eg it only works if I do {% order_total "" as order_total %}

epicowl: paste your template tag code

apollo13: that's the problem. i don't understand what's calling what, and the stack trace looks so circular that it's not being helpful

nkryptic: for my own example I have managed to make my nested model abstract and I can now skip a level ! :D

thanks

klrmn: well, what makes you think that this method should get called at all?

klrmn: i normally do a ctrl + F on the page the error is printed on. I search for my project name and then scroll down to the last match.

apollo13: because it's called https://github.com/klrmn/moztrap/blob/suite_res... in the template

ineedarobot: what application are you issuing ctrl-F in?

klrmn: open a shell and call it in the shell

maybe you get an exception the template system catches

apollo13: the template system having a seperate error catching method would probably explain why the stack trace doesn't include anything in my project except for the last line

apollo13: i used another page in the system as an example of how to do this page…added the same logging in the same places, and it gets called just fine

well if you can't find anything throw pdb at it and step through

klrmn: so, this works? ...filter(runcaseversion__caseversion__case__suites__in=self) from L323 in models.py. I thought you needed to assign a list value when using "__in"

nkryptic: that's the biggest question of all

nkryptic: i am wondering if the problem is at https://github.com/klrmn/moztrap/blob/suite_res... … i don't know what that line does.

klrmn: why don't you move the log to the start of the function?

apollo13: trying that now

if that works, your function is raising an error

that is in fact working. so i need to come up with something that works for line 323

apollo13: wonky m2m relationships makin my life miserable

I'd rather say db design fail, but well ;)

apollo13: i agree on that, but it's not my project to re-design the db for

klrmn: anywhere you have code like ...suites__in=self does it work to change it to ...suites=self

nkryptic: sounds worth trying

omg, nkryptic, you're a genious!

South complains that the field 'Task.created' doesn't have a default value and is not NULL, it's a trivial DateTimeField field, how would I best go about handling this in django 1.5?

right now I have "created = models.DateTimeField(auto_now_add=True)" should I set a default value?

dexterity: south asks you if you want to set a default value for the migration
