LogoS[ES]: some people would suggest you need to stop using Admin, and build a proper management interface for your site :)

FunkyBob, sure! but it is for a very small project in a small LAN with 5 devices

Thanks for the tip!

Have a wonderful weekend, see you!

how to list user.first_name + user.last_name instead of user.username in all ForeignKey(User) dropdowns and ManyToMany(User) multiple select?

I read http://initd.org/psycopg/articles/2018/02/08/ps... and I concluded that moving forward my requirements.txt should have psycopg2-binary. Is this correct?

"The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources." https://pypi.org/project/psycopg2-binary/

newdimension: that's what I use

psycopg2-binary?

yes

ok, thank you

was not aware of advice to not use it in production

Hello django people!

hi

I'm kinda new and have a bit of an architectural question

I have a problem that I believe I could solve using either a Formset or several individual Forms

is there a preferred way to do this? i.e. when both could be applied, does one of them have a clear advantage?

that depends on what the problem is

of course, I'll specify

I want to build a view for creating an instance of Model A + a few instances of model B that have a foreign key pointing at the newly created A

but the number and some of the fields of the Bs are already known at the time the form is initialized and should not change

sounds like you want an inline formset

So there'd be 2 forms, a regular ModelForm and an inline formset?

yes

oh, there's a max_num parameter

that way I can stop the formsets from creating more than the pre-determined number of things even if somebody fumbles with the request

yes

neat

I'll give it a try

I had seen inline formsets before but had assumed they were only supposed to be used for variadic formsets

understandable

uhm wait

there seems to be no "initial" keyword argument on inlineformset_factory

do I have to populate it manually somehow?

doesn't the factory function return a formset class ... and you pass initial to that?

ooooh right

i see it now

of course, i could instantiate that several times

should, even

making a new factory on every request is probably not the smartest thing

another question, if it is okay

is it a bad idea to put a lot of logic into the view? or into a form class?

no

okay, so inlineformsets don't allow for an initial parameter

i think they're more suited for the case when all the objects already exist in the DB and are related

i don't want to save my objects before i've received and validated the form (don't mutate in GET requests and so on)

so I'll try a modelformset instead

muvlon_: I suspect it's expecting a queryset of objects to edit

but I'm not sure... I don't use formsets

I've only recently started

I used to just shove a lot of forms into a single <form> element

and make sure the prefixes were unique

quite valid

Hello. I have a project with 2 kinds of users. Mayor and Residents. What would be the base way to create the two types of models? Profiling or Extending the BaseUser? Users should be able to post complains and ask questions to the mayor. Mayor does not have address, gender fields etc but residents have those. Thanks.

why would they be two types of model?

isn't it just a flag on the user record to indicate a mayor?

ok

that might work

alternatively, you can have three models: User, Mayor, Resident

both Resident and Mayor have a OneToOne to User

ok

address, gender etc are then fields on Resident, not on User

so the difference between a Mayor and a Resident is that you've stored the extra fields?

but since there will only be 1 mayor, I think I should only use OneToOne Field with a User(which may be both mayor and resident)

is that right?

ah, well, enforcing that only one person is Mayor ... can be fun :)

also... is every Resident necessarily a user who can log in?

yes

Hi all. Having issues getting django to log to stdout. Reading docs it seems like I just define a LOGGING dict in settings.py? Does this look wrong? https://dpaste.de/5q1T

talking about runserver, or...?

yeah runserver

looks ok, Draconis

is there something that makes you think it's not working?

Do you need to store when the mayor is mayor? Or is the data just a snapshot in time?

I would like to have an app called products which has the models category and offer. I'm wondering about how I can have those two urls in the same urls file though? I would like to have the url mysite.com/categories/1 or mysite.com/offers/1 I guess.
