does anyone know of a web service which allows access to high resolution multi spectral satelite imaging that also offers a multitude of passes

like we used to have this thing called digital globe but i believe it's like a quarter million a year minimum so it's not exactly useful for what i need

react or angular with Django?

de_dust: check this out https://www.youtube.com/watch?v=S8wayjpaUJM

it's about django and react

de_dust: Django doesn't have much of an opinion. React seems to be a more popular choice these days.

well, can't find a solution better than dynamically generating classes lol

let's see if i can get this working

de_dust: aurelia :)

mathu: Scrapy?

mathu: What is leading you to wanting dynamically generated classes?

mattmcc: i'm not actually writing a web archiver, that was just an analogy

which reminds me... I was going to rewrite django-filem using aurelia...

mattmcc: i need a user to be able to configure new sources to query and how often to query them

mattmcc: django-cron and friends work by writing a class per job or somesuch

So run a generic task, say, every minute and have it determine which jobs to run based on querying some table.

mattmcc: i don't have the luxury of knowing my jobs in advance

job(id, name, interval, last_run)

FunkyBob: You lost me at node.js. Though maybe that's what he's looking for.

I'll have to do some jquery soon. That should be enough.

AtomicSpark: eh?

mathu: I do something very close to this already, a management command that cron (not django-cron) calls every minute, which polls client sites and runs whichever importers have been enabled in their respective admins.

mattmcc: part of why i want to use a lib is because there are other scheduled tasks that i will know in advance

AtomicSpark: you mean because aurelia uses node to build?

mattmcc: django-cron runs a manage.py command in regular cron, i do have to do more or less this regardless

django-cron handles the last_run bit already, provided i can make its classes

Well, you can continue using some existing tool for the tasks you do know.

having to write a job scheduler and also import a different one is kind of embarrassing haha

idk

But I wouldn't use it if it requires generating classes on the fly, that just seems more work than necessary.

FunkyBob: I haven't dipped my toe into node.js yet. It's whats keeping me from manually compiling things like bootstrap.

turns out it's really really easy though

AtomicSpark: sure, but who'd use bootstrap? also, with Aurelia, you can pretty much forget it's node

it's just a call to `type()` and then if you want it to be scoped within some module `globals()['NewClassName'] = type(...)`

i think doing that is actually possibly less work than implementing a job queue. the reason i'm hesitant to do the dynamic class generation is that it just seems like awful practice

but, well, this is basically a reverse-paid internship. if they want to be super picky about my code they can pay me for it

Nah, it's a feature of Python.

Django has metaclasses all over the place.

i trust Frameworks to do it more than Me

..And factories.

AtomicSpark: honestly, Aurelia sets up the whole project for you, and has the build / compile / watch+serve stuff pre-set for you

you can then get on with writing you html/js (as separate things, unlike that moronic JCX shit)

mmm, wait, these configurations need to persist

oh okay my studybuddy is calling it a night

maybe i'll be back to commit more sins tomorrow

peace

Persist in a job table, perhaps? :)

Hello, I am using django wizard and in one of the steps I am trying to understand how can I combine two forms in one step. Modelform(etc..) and modelformset_factory(Images, form=ImageForm, extra=3)

apostal: you mean FormWizard ? from the django-forms package?

FunkyBob: yes

hmm....I have an old site that does that, somewhere

FunkyBob: I used a patch, https://code.djangoproject.com/ticket/18830

FunkyBob: but problem I have is in class ContactWizard(SessionWizardView): def done(self, form_list, **kwargs): --------- form_list does not return encapsulated forms cleaned_data

Is it wrong to upload my migrations to the productive Server? Locally I am using sqlite and on my server mysql. Sometimes I'm encountering errors because of this

Migrations are how you update your DB state, regardless of environment.

test

anyone around?

mad_moses: errors because you fail to commit your migrations to your repo?

giot: yes

FunkyBob: no, everything is uploaded. but if I run manage.py makemigrations on my server, i got new migrations which make troubles

mad_moses: you _don't_ run that on your server

you just run "manage.py migrate"

to _apply_ them

you already made them in development,

Although if running makemigrations on the server causes problems, that suggests a whole other issue.

how can you have new migrations...?

indeed, it does

It should really be a no-op.

If it creates migrations, that means your models and migrations aren't in sync.

which means your server isn't using the same code you have in dev

FunkyBob: okay thank you, I will have a look at this

so... who has been making changes in production, mad_moses ? :)

FunkyBob: no one, not understanding what is happening

how do you transfer your code to the server?

FunkyBob: git

and what does "git status" show on the server?

git status

# On branch master

nothing to commit (working directory clean)

ups

git pull => already up-to-date

so, something on your dev machine wasn't committed... or someone forgot to run makemigrations there

which would suggest your tests are insufficient :)

Hi folks, I'm stuck trying to understand why I can't query the model with a datetime object. I need to convert a timestamp str (in Unix time) to a datetime obj, and use it to find entries newer then what's in the datetime obj. I sort of successfully achieve the conversion from timestamp to obj, but can't use the object agains a DateTime field in the model. Here's a very simple example from ipython. Why do I get nothing at line Out[10], while using anot

her datetime object I get the result at line Out[17]. https://dpaste.de/7YLQ/raw

FunkyBob: you are right, manage.py is not using my virtualenv. How do you activate your virtualenv within your manage.py. I did someting like this in the past: git status

# On branch master

nothing to commit (working directory clean)

mad_moses: you don't

ups ... i mean this: sys.path.insert(0, '/var/www/mars425/files/scripts/python_productive_env/local/lib/python2.7/site-packages')

yeah... no...

why not just activate your virtualenv?

FunkyBob: so how do you tell your manage.py to use a specific virtualenv

or specify tyhe python in the virtualenv?

you DON'T tel manage.py to use it

it uses whatever python it finds

FunkyBob: because then i need to do one more step :) and I could forgett to activeate my viertual env

how do you run your django in production?

Use django-admin, which has the virtualenv's Python binary hardcoded.

mad_moses: if you can even run your django project without virtualenv active, you've done something very wrong

I mean, it's not like you installed Django globally, right?

FunkyBob: no, I do it this way: https://dpaste.de/dq89
