DjangoBot: #django

rozwell: The reason I ask is because I have encountered problems that have occured on the production server that didnt happen on the localhost.

resno: well i recommend you code defensively

resno: that is learn the differences between the two environments and keep them in mind while you're developing

rozwell: Is there a major difference between running in Apache vs Lightspeed, etc?

resno: but a staging setup will help you identify these problems before your code goes live

resno: yes, there are differences between how different webservers work and interact with your projects

rozwell: id figure nothing can be standard and easy.

resno: well most code wouldn't run up against areas where there are differences

The nice thing about standards is that there's so many to choose from.

resno: but as far as configuration, these things are vastly different

so... any concerns about running django in python 2.4.3...? :)

mgeary: no

awesome. thanks

mgeary: django works fine in any 2.x where x > 3

great

hey, help me find a good solution to this webserver scenario

i've got a client with a server something.client.com. That domain is already running apache+php on port 80. However, i'd like to run a django app on the same domain.

mod_wsgi

well, right

so can i just point the WSGIScriptAlias directive at a subdirectory?

i've only set up mod_wsgi as wholly-django virtualhosts before

Don't put the Django app under DocumentRoot.

no, i know

but something like:

WSGIScriptAlias /myapp/ "/path/to/my/django_projects/proj_name/apache/my_proj.wsgi"

That works.

where /myapp is the subdirectory in the "normal" php instance?

awesome

very awesome

thanks

The only issue is that your URLs will start with /mayapp/.

that's okay

you mean they'll be: something.client.com/myapp/<start here>

right?

'cause that's fine

They will also start with /myapp/ in Django.

You'll need to compensate for that in urls.py.

ah, right

i can live with that

thanks

When I try to syncdb why I get this error ? Table 'myapp.auth_group_permissions' doesn't exist"

auth_group_permissions was never created when I set my auth tables...

Hi there. Had a question on this ticket: http://code.djangoproject.com/ticket/7561

my django trunk is in /usr/lib/python2.5... how do i change it so it uses another django version located at another place on my hdd?

anyone have some good ideas on alternate signals / methods for a 'post_syncdb' that triggers AFTER the loaddata, etc. have all ben called?

i have an imagefield.. and its working properly.. but.. how can i see the picture in the admin? without clicking on it

the use case is for large fixtures that take >15 seconds to load and we want to load them selectively based on some flag

m1chael: custom templates or widgets

I changed the name of my app and model, and now I need to change the authentication to reflect the changes. Do I just do a syncdb. If I do that , will it reload all the fixtures I have in my other apps. Is there a way to just update the authentication for that one app without messing with anything else?

is it a "bad thing" to put business rules in overridden 'save' methods of my models?

i wouldn't think so

Nah

they're not guaranteed to be called in certain conditions IIRC

I couldn't think of any reason not to

GotenXiao: I will be calling save () explicitly

Hey guys, anyone have an idea what this error may mean? "Unknown column 'xxxxx' in 'field list'", xxxxx being some field in my models.py

lyaunzbe_: you changed your model definition but not your database structure

drgalaxy: Im not sure what you mean exactly. Doesn't executing syncdb correct this for you?

in general, it's not necessary to do form validation if your application's server is protected by a firewall, right?

moobles: ...

moobles: Orthogonal concerns.

moobles: wrong ^_^

If you've already run a syncdb on an app, and you are going to syncdb for another app you are adding. Will the initial_data fixture get loaded again in the original app? Or does it only do it when you first syncdb the app?

moobles: Well, I guess that depends. Are the people behind the firewall infallible?

lyaunzbe_: no, syncdb will only create tables if they don't exist. changes are not managed

lyaunzbe_: Django never alters existing tables.

drgalaxy: So then how would I make these changes then?

hi there, i have a form derived from a model. this model has a textfield named input. if i use that in a template with {{ form.input }} it gets rendered as textarea, which is fine. how can i adjust the size of that textarea? does form.input has any options i can pass to it?

kazamatzuri: The easiest way would be with CSS.

lyaunzbe_: you can either modify the database yourself OR dump your data, blow away the the tables that changed, resync, and re-load

lyaunzbe_: manually alter the table, or drop the table and start over.

You guys mean just manage.py flush?

mattmcc: hm ok, i feared this would be the answer ;) thanks anyways

lyaunzbe_: that would work.. if you don't need any data in there

or look into the schema migration apps south or schema evolution

lyaunzbe_: if you need the data, do a manage.py sql appname, to see how your new sql will look. Then manually alter the table using sql.

hi all. i want to render an xml file as html within my django site. xslt seems to me to be the right tool for this, but i'm not sure how i would go about using my base django template alongside this, so that the xml (rendered as html) fits seemlessly within my site. do anybdy have any pointers?

hewer: depends on your use case - is this one time (static) or every time?

i have an imagefield.. and its working properly.. but.. how can i see the picture in the admin? without clicking on it <--- widgets or modifying template file.... which template?

Change the admin form to load it.

drgalaxy: the xml will change, but not requently

*frequently

i'd like to augment the existing DateField by allowing entries such as "today" "a week from tuesday" and "april 18"

hewer: unless XSLT is really necessary, I would just write a script to parse it into html and run it outside of the web context. then either {% include %} it in your templates (assuming it lives in a template dir), or read the html in your view and pass it in to your template context

damn .. i wanted my commentform to display as table .. whough when doing {% get_comment_form for entry_object as form %} {{ form.as_table }}

Is it possible to do a tag in a django template to see if a variable is greater than a number

it renders that hidden ugly field ..

drgalaxy: that's what i was originally thinking of doing, but it seems to me that xslt could save me quite a lot of work, if it's possidle to use it

writing scripts to parse xml isn't much fun, imo

:p

hewer: I hear that, I guess it will depend on the data and your familiarity with the processes as to which is easier

You can have the XSLT generate Django template directives, then process through both XSLT and Django's template engine.

naaah .. rendering commentform as table seemed as it was not meant

kcbanner: the general philosophy of the template language is that it shouldn't be treated as a programming language

I have a strange error, and I'm looking for clues: Using mod_python I get the error: 'str' object has no attribute '_default_manager'. However, using the dev server it works fine! :( Full error: http://dpaste.com/25027/ Anyone has similar?

ivazquez|laptop: good point

ivazquez|laptop: i am a little unclear as to what you mean (my knowledge of the django template engine is minimal) - could you please elaborate or point me in the direction of any useful resources?

kcbanner: if you really want that type of functionality, you can add your own template tags. This one provides greater than, less than, and equality in an 'If" tag: http://www.djangosnippets.org/snippets/1350/
