Re: Finding a developer

[Doug Snyder]

How much you need to worry about differences in ROR or django infistructure
probably depends a lot on what your project entails. How much is it a job
that requires a framework? Django or ROR can be used for pretty common
generic web projects like a simple CMS system or it can be used for an
involved web app that's got a lot of specific functionality. I guess you
have to look at your specific functional needs and see how demanding or not
they are and get a basic idea of how they might work under either
framework. I've got a web app brewing in the back of my mind ( that I
haven't coded yet :-/ and it relies on functionality through a specific
mathematical python package. Python has a lot of packages written for it
that may or may not have anything to do with web development. I'm not a ROR
person, but I think ROR and Ruby itself have much less packages written for
it since its more of a web development and server scripting language, while
python is the language of choice for a lot of people that want to write
code in an easy language with quick development time. For 99% of web
projects this aspect of python may be completely irrelevant because you
won't be using any of its plethera of packages. But is you need some
specific, not so common functionality, see if there's some python code that
does what you want, and if Ruby has that also. I like python in general,
and so when I write websites its natural to use django.
If you're doing something more like a run of the mill website there's less
concern about which framework you choose.
But if you are going to scale or use large data stores and use
alternative's to your SQL DB and really push the limits there's a lot of
considerations that I'm not really up on . . . but you should either
understand these or find someone else that does ( not me :-0 )

Re: Is their an easy way to implement an ordered list of, say, urls in Django

[Doug Snyder]

OK, cool, thanks.
I'll keep in mind the custom SQL solution for the future but for this
project I think I do the editing on the front end ( see below)
I have a strange background where I'm learning django but have never used
SQL outside of django's ORM.
I haven't played around with custom SQL since I don't know it.
Is it just a matter of basically copying the code you listed above and
putting that somewhere in my model?

Yea, sorry I wasn't very clear. I am thinking of doing the editing on the
front end using KnockOutJS which is a ModelView  ViewModel implementation
in javascript. So I would pass the list to KnockOutJS in a mirrored data
structure and edit it there. SO I guess it is like dumping the whole list,
but since I want the user to edit it on the front end the ineficiency is
acceptable. I guess Javascript lends itself better to editing and inserting
to an ordered list than SQL does and the data has to go the front end
anyways.

Re: What to Django people have to say about Javascript frameworks to complement Django's philosophy on the front end

[Doug Snyder]

Another framework I looked at is SproutCore. This seems to be more focused
around widgets like many javascript libraries have been before it. I'm not
sure how extensible these widgets are and how quickly I would run into
limitations of using them for things they weren't specifically designed for.

Re: What to Django people have to say about Javascript frameworks to complement Django's philosophy on the front end

[Doug Snyder]

Another interesting library just launched is Webbot (
http://www.webbot.ws/Home ). This is actually a python lib intended for
django and app engine that lets you write generalized front end UI's using
python and has a GUI that helps you build them by generating python for the
UI without writing any code. It looks like an awesome idea, but I'm sure
its not super mature yet but it looks like an abstract frame work that can
be built off to build in support for what ever front end technologies you
choose. It would be cool to see this project grow and for people to
contribute code that adapts the abstract python UI representations to
different javascript and front end libraries and technologies. The author,
Timothy Crosley is on this Google Group and Webbot also has its own Google
Group here: https://groups.google.com/forum/?fromgroups=#!forum/webbot

Sorry, looks like I was wrong about batman. It can work with django, I just
forget sometimes that more people watch movies than write web apps.

Re: django , python and ides

[Doug Snyder]

I use an IDE called Aptana Studio 3 and like it.
I can't say that I've tried a lot of IDEs and I tend to get more
opinionated about programming languages and technologies than editors
but when I got into Django I looked at some options and found Aptana to be
the most full featured free and platform independent option that I could
dig up. Its meant to be a web development IDE so it has some nice
HTML/CSS/JavaScript/JQuery niceities like code coloring, code completion
and things ( which helps me get through the design and onto the important
stuff: Django ). Aptana is built on top of PyDev, the python plugin for
Eclipse ( which has been an opensource standard IDE for a good long time ),
so its got everything python from PyDev and then has a few Django
conveniences built in too, like some common command line django commands
available from the IDE's GUI, and a (i)python shell that loads up your
django environment and lets you do stuff like play with your models to get
them working before you add in extended admin functionality for them or
cook up a proper web interface.
One complaint I have with it is that its a little hard to work with Aptana
Django projects if you are developing them on multiple computers because
the project profile has hard coded paths. The work around is to ignore them
in your version control. One the first computer you start the project with,
Aptana and PyDev will create well formed project meta data file ( one for
each ). You manually copy the new computer and manually edit the hidden
files and change the file paths in the XML to fit the different file
system. It could be worse and I'll probably stop complaining once I write a
script to do it for me.
All around Aptana offers a lot.
I'm believe in simplicity when it comes to programming
When it comes to IDEs I believe in convenience.

Re: saving latitude and longitude values in django

[Doug Snyder]

I think you'd at least want to use either a DecimalField or FloatField for
the lat & long numbers.
There's a nice GIS package in django called GeoDjango, it has lots of built
in functionality for all kinds of geographical things.
This may be over kill for your application but I thought I'd let you know
it exists.
One thing it allows you to do is query the DB based on location, i.e.
distance between points with lat & long.
You could compute this using a standard norm calculation but its slow
compared to using a native DB query.

Re: Psycopg2 on Mac OS X (Snow Leopard)

[Doug Snyder]

I don't have a very specific answer for your question. I just started doing
my django dev on OSX coming from Ubuntu
My understanding is that Home Brew is a better solution than Mac Ports, I
have heard some people being very critical of Mac Ports which I think was
once the best solution for python environments on OSX but I think has been
mostly replaced by Home Brew. Switching over may solve your problem
automatically and may make life easier down the road too. But maybe someone
else will have a more knowledgable, specific answer to your specific
problem.
Another solution that doesn't require and headaches is that Mavericks, the
new OSX release may still be free for download. They announced it was free
but the way they worded it made it sound like it may have only been free
for the day it came out. Not sure if that's a road you want to go down or
not.
Good Luck,
Doug

trouble going from django on Windows to Ubuntu using Eclipse & Aptana Studio

[Doug Snyder]

Hi I'm pretty new to Django but I had an app working OK so far in
WIdnows in Eclipse with the Aptana Studio plugin. I installed Eclipse
and Aptana on a Ubuntu 11 machine and copied the code into a new
project and when I try to run the (development) server I get some
errors in django itself that are incomprehensible to me:

Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
utility.execute()

Could someone explain where the problems might be?
Even a beginning of a solution would be appreciated as I don't know

Re: Angular and Django

[Doug Snyder]

be sure to check out:  django-angular


I'm just starting to use angular and django together.
I plan on using django's integration with Content Delivery Networks to
serve static files including the Angular app files
( AngularJS itself can already be served with content delivery just by
using  the URL google provides:
http://blog.angularjs.org/2012/07/angularjs-now-hosted-on-google-cdn.html
but also image files that require fast response time.
Django has nice tools to preprocess static files using the

django-compressor 

Things like 3rd party logins are basically solved and modularized into
prepackaged apps:
django-social-auth 


I also use python libraries that aren't associated with django,
there's really not much that ISN'T written in python these days.
I am able to get nice packages to access Web API.

I'm using GIS data in one of my projects and django makes it really easy
with:
GeoDjango 


which pulls together many ongoing GIS packages all into one simple,
extensible interface that fits right into django.
So I guess there's a lot of reasons to use django with Angular, but it
depends on what you are trying to do.
Moving stuff to the front end does make the back end less important, but
you still need a backend unless you can really
do what you need to with solutions that basically amount to having your
Angular app have all the functionality and having
storage in a cloud db.
I've also thought of using Flask, another python web dev platform. Its
supposed to be lighter weight than django,
but lighter on functionality and conveniences and an active developer
network. If I wasn't using any python awesomeness,
maybe a Flask backend would improve server performance, but everything I'm
working on can benefit from django so I
haven't taken the time to learn Flask.

Hope this helps.
Django and AngularJS are two scoops of webdev icecream with sparkles. Hope
you enjoy.

Doug

Re: Angular and Django

[Doug Snyder]

compared to other js webapp solutions like Ember or Knockout,
Angular is more powerful but maybe a steaper learning curve.
It lets you get really under the hood and has a unique feature called
directives where you're essentially creating html tags to use as widgets.
Its state of the art and Google folks aren't afraid of getting into the
pudding.
As people write more and more reuseable directives to share around,
its going to become more and more powerful.

Re: Angular and Django

Angular directives and binding are actually more powerful than Django's
templating!
