Re: serve static files

[Jani Tiainen]

If you're using contrib.staticfiles app, your DEBUG is True and you're using 
runserver django automagically maps (overrides) your staticfile serving.

If you want to manually add staticfile serving, you have to give --nostatic 
parameter to runserver to omit all magic that happena automatically.

I have a title and a header block which normally contain static text
but for some pages I need to display some dynamic information
contained in a template variable.

So I might have the template variable: {{ app.name  }}

and the block code:

{% block title %}
 {% trans "{{ app.name  }} Information" %}
{% endblock %}

Obviously this doesn't work. What is the correct way to solve this
issue? I've done it in the past but I can't for the life of me
remember how.


This was actually significantly easier than described above. The 
following works just fine and is much simpler than having to deal with 
string concatenation in templates.


{% blocktrans with app_name=app.name %}
Edit {{ app_name }}
{% endblocktrans %}

Paginating YouTube API results

[Sithembewena Lloyd Dube]

Hi everyone,

I am using django-endless-pagination to paginate YouTube API results. I
have a view called 'search' and a url pattern as follows:
url(r'^search/$', 'find_music.views.search', name='search'),

In the view, I check request.method and handle it as follows:
- if POST, get search term and fetch youtube api results as list, which i
paginate in template
- if GET (user clicks pagination, url e.g. '/search/?page=2'), i look for
request.GET['page'] , which I would like to use to paginate my video list
created in the POST.

Question is, how best can i keep my video list from the POST method across
requests, so that i can paginate the same list? I have no search params
when users paginate, so I need to keep the original list and paginate that.
Any ideas?

Thank you.

Sithu Lloyd Dube

make sure the folder containing wikicamp is inside your PATH so you don't
get import errors. make sure there's an __init__.py inside it.

perhaps you could debug the import error like this:

$ ./manage.py shell
>>> import sys
>>> print '\n'.join(sys.path)
>>> import wikicamp
>>> from wikicamp import wiki


In the future, please post an entire traceback along with your question.

while developing (or learning), you don't need a deployment
environment.  if you have a working Python interpreter in your
machine, just do "python ./manage.py runserver" to run the development
server.

later on, you would need to push the developed project to a real
server.  that's when you have to check your deployment options.

serve static files

[Wesley Ni]

I hit an issue when trying serve static files.

In settings, debug is True, and with the followinig:
STATIC_ROOT = os.path.join(freelancer_path,"staticfiles")
STATIC_URL = '/staticfiles/'

urls.py:
(r'^staticfiles/(?P.*)$','django.contrib.staticfiles.views.serve',
{'document_root' : STATIC_ROOT,'show_indexes' : True}),

Problem is, when accessing http://127.0.0.1:8000/staticfiles/, I got this:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/staticfiles/

Why? I thought I would get folder indexes because I set show_indexes to 
True.

And, later, I find that, if I set the url pattern prefix not same to 
STATIC_URL, 
say, maybe :
(r'^files/(?P.*)$','django.contrib.staticfiles.views.serve',
{'document_root' : STATIC_ROOT,'show_indexes' : True}),
And, then, http://127.0.0.1:8000/files/ is OK to show folder lists.

Could anyone help explain and fix?

Thanks.

This is the third post in which you've posted screen shots of the errors
you get.

Please don't do that. Copy and paste the error text including the traceback
i.e. the content if the lower panel in you IDE.

In this particular case you've attached a file named 'python
models.py' but with contents
that seem to be a PNG file. And I can't open it (the image viewer
reports it is corrupt).

Also, make sur you report the versions of Django and Python you are using.

Re: [] error

[Apokalyptica Painkiller]

Hi Patrick, why don't you try to re write that sentence again? May be you
write it wrong. I remembered had same error.

I wanted to see your code from models.py but it seems to have nothing in it.

[Mantas Zilinskis]

for your environment:
you should definitely look into this

 if you're using mac also this
http://hackercodex.com/guide/python-virtualenv-on-mac-osx-mountain-lion-10.8/

setup your settings.py

Hi,

What is the value of DATABASES['default']['ENGINE'] in your settings.py?

I think you have entered only 'sqlite3', but django wants you to enter 
the full path to the module (ie: 'django.db.backends.sqlite3').

how to model a reflexive many to many relationship?

[slim]

I'm trying to build an e-learning platform
I have *users (Utilisateur) *who can take several *courses* ,each course 
have several *modules* and a module can be in several courses
a user can be a student or teacher or admin, a student is "managed" by a 
teacher or several and a teacher can also  be managed by a teacher (if he 
is a researcher) ,teachers are managed by admins

this is my conception :



I'm not familiar with many_to_many and through concept, please correct me
 this is my django models :

class Utilisateur(models.Model):
user   = models.OneToOneField(User)
role   = models.CharField(choices=ROLES,blank=False,max_length=50)
managed_by = models.ManyToManyField('self', 
through='UtilisateurRelationship', symmetrical=False, blank=True)


class UtilisateurRelationship(models.Model):
managed = models.ForeignKey(Utilisateur)
manager = models.ForeignKey(Utilisateur)


   
class Course(models.Model):
titre  = models.CharField(blank=False,max_length=100)

class ModuleCourse (models.Model):
module = models.ForeignKey(Module)
course = models.ForeignKey(Course)
order  = models.IntegerField(blank=False)   

class Module(models.Model):
titre = models.CharField(blank=False,max_length=100)
belong_to = models.ManyToManyField(Course, through='ModuleCourse')

class UtilisateurModule (models.Model):
user   = models.ForeignKey(Utilisateur)

Re: django template loop collections.defaultdict(lambda: collections.defaultdict(list))

for obj in queryset:

my_dict[int(obj.position.split('-')[0])][int(obj.position.split('-')[2])].append(obj)

for obj in my_dict:
my_dict[obj].default_factory = None

return Response({'queryset': dict(my_dict)},

groups = {{ groups }}


{% for cols in groups.itervalues  %}

You can create it using a defaultdict if you want to, but once it is
created, and before you pass it to the template, loop through all the
values of your outer dict and coerce them to dicts using dict(). You are
already doing this for your outer defaultdict, which is why the first loop
works in your template.

If I update my chat sub page, inputs are reset (seems

You can always have some field that keep when the chat was

that time.

Then what would be the good / best method to update only
the chat content ?
(I have 2 ideas but they don't seems very Django'ic)

2.
For now, I update the content every XX ms with a
periodic request client
side.
Would it be possible / preferable to have a push from
server when new
data comes or is there a better way to update this kind
of content ?


Trying to hack django to get server push would be hell (look
into tornado). If you really need server push, you may need
to look into other technologies, like nodejs.

Using the periodic request client-side is what is mostly done.


Hope this helps.

HD.


1.
My question was not clear enough,
Let's admit i have this template page :

/{% for elem in data %}//
////
//{{ elem.datetime }}//
//{{ elem.name 
}} ://
//{{ elem.text }}//
////
//{% endfor %}//
//Text : /

and this view.py :

/def getchat(request)://
//template = loader.get_template('chat.html')//
//context  = RequestContext(request, { 'data': lines
})//# lines is an array with lines
//response = {'html' : template.render(context)}//
//return HttpResponse(json.dumps(response),
mimetype='application/json')/

and this javascript :

/function getchat()//
//{ //
//$.post('/getchat')//.done(function(data, textStatus,
jqXHR) //
//{//
//$("#chat").html(data["html"])//
//})//
//}

/Then whenever I call getchat() in javascript, the chat is
reloaded with all the old lines, this point is ok, but
 field is reseted too, which mean that if user was
typing, the content is erased.
I would say the solution is to create a second function in
view /getchatcontent/ that will send only the content so I do
not
update the whole thing. Do you think it is the right way ?


2.
lets use periodic request client-side.



Thank you for your answer



There is nothing more in chat.html
there is a base.html template that contains

///
//{% load staticfiles %}//






//post//
///


appchat.js


/$(document).ready(function()//
//{//
//$("#addline").click(function()//
//{//
//addline($("#chatname")[0].value,
$("#chatinput")[0].value);//
//$("#chatinput")[0].value = "" //
//})//
//setInterval(function() { getchat() }, 1000);//
//})//
//
//function addline(name, text)//
//{//
//$.post('/addline', {"name":name, "text":text})//
//.done(function() //{//})//
//}//
//
//function getchat()//
//{ //
//   $.post('/getchat')/
/
//.done(function(data, textStatus, jqXHR) //
//{//
   $("#chat").html(data["html"])//
//})//
//}/


Now you have everything, does this seems the right way to do what
I want to achieve with django or is there a better way ?

my_dict[int(obj.position.split('-')[0])][int(obj.position.split('-')[2])].append(obj)

Basically I have one field in the queryset called position (the format is 
N-N-N-N) and I need to create the dict as in my question.
Sincerely, I don't know how I can create the dict without using defaultdict.
