Re: Avoiding code repetition in views

[Timothy Makobu]

@grimmus

I have a file called shared.py, and In it, i have created a
dict template_dict { } which has stuff that all the views share. I import
it into views.py and any app that will use that dict. I can then add more
items or alter existing ones via template_dict.update().

Re: how to manage range of hours in models and forms in django1.4

[Jon Black]

I understand that institue_hours_of_operation is a count of the
hours the user has worked, is that correct? If so, I suppose you
just need to count the hours with each form submition and add
that to the current institue_hours_of_operation value. You can do
that logic in a few places. In class-based views, I tend to put
it in form_valid().

Apologies if I've misunderstood :)

Re: how to manage range of hours in models and forms in django1.4

[Nikhil Verma]

Hi Jon

Yes it is the count of the hours.They will enter in the following manner "-

Monday : 0900-1800, Tuesday and so on ... This will be entered by the user
who is filling the form.

Now the text Moday(weekdays can be hardcoded but i personally don't want.)
Now if you see this is a simple CharField where the user enters details for
the number_of_hours.
So i want to know what type of model field should i create CharField or
Time Field.

If i   go for CharField it will simply save the details like 0900-1800. So
if i need to know how many hours that particular person is available for
work then how will subtract that from CharField.

So i need help to know what exactly the field i should create such that it
satisfies the template look and backened queries also.

Re: how to manage range of hours in models and forms in django1.4

[Jon Black]

If the days have to be hardcoded (I imagine you have a row/field
for each day), then you could use a hardcoded string for the day
(not editable nor related to your model), and provide two Time
fields. Using Time gives you advantages:

* You can use python's DateTime module to calculate the hours
* You can more easily use a funky date/time style widget if you
ever need it
* You will avoid making mistakes trying to calculate the hours
manually
* You can validate the form data using python's date/time module

If you're really open to suggestions (just thinking outside the
box, and possible outside of the scope), but you could use a
separate table to record all hours recorded rather than just
counting the hours as they're entered.

Or just use an iframe in your template that loads the gigs rendering view.
Iframe bad, yes, and all that, but the simplest solution in this case if
your layout can handle it.
A variation is to have them loaded by Ajax, with the drawback that
javascript-disabled browsers miss content. As I browse with noscript all
the time, this isn't a big problem. If I get to a page I'm interested
in, I will grant the domain the privileges in an instant.

Point being, refactoring code duplication isn't limited to the django layer.

Untested, but I'd try this:
class DaysOfWeek(models.Model) :
name = models.CharField(max_length=32)

class BusinessHours(models.Model) :
day = models.ForeignKey(DaysOfWeek)
start = models.TimeField()
end = models.TimeField()

class Institute(models.Model) :
   # ...
   business_hours = models.ManyToManyField(BusinessHours)

Not sure if the Admin handles this ok though. An alternative:
class DaysOfWeek(models.Model) :
name = models.CharField(max_length=32)

def __iter__(self) :
return self

def next(self) :
for entry in DaysOfWeek.objects.all() :
 return (entry.id, entry.name)

class BusinessHours(models.Model) :
day = models.CharField(max_length=32, choices=DaysOfWeek)
start = models.TimeField()
end = models.TimeField()

I would create an extra Model which defines these opening times:

class OpeningTimes(models.Model):
day = models.CharField(max_length=10)
start = models.DateTimeField()
end = models.DateTimeField()

and define a manytomany relation ship from the UserProfile to your 
OpeningTimes model.


I've opted for the DateTimeField here, there's no Time Field in django 
by default. But you could just use any date (maybe use some kind of 
default date or use the current date)
and make sure the time has been filled in correctly. And then just 
extract the right hour from the DateTime field.

Jonas;

The context_processor will be called for each and every RequestContext (so 
for each and every view AND templatetag creating a RequestContext), so 
better to avoid anything "intensive" here. 

Also, it won't have access to the existing context - which may or not be a 
problem, but for something "my favorite books" (which really means : "the 
favorité books of request.user"), you can bet one day or another you will 
want to show "the favorite books of _another_ user", and this is something 
that won't work with a context processor.

To make a long story short : use a custom template tag that will take the 
user as an argument. 

My 2 cents...

Re: how to manage range of hours in models and forms in django1.4

[Sunny Nanda]

One way to store such information can be like this:
Create a model "Day". This will hold entries for each day i.e. from Monday 
till Sunday
In the UserProfile model, create a ManyToMany relation to the above defined 
Day model through an intermediate table (say WorkingHours) which can hold 
the "from" and "to" time.

Partial example below:

class UserProfile(models.Model):
> working_hours = models.ManyToManyField("Day", through="WorkingHours")
>
> class WorkingHours(models.Model)
> profile = models.ForeignKey("UserProfile")
> day = models.ForeignKey("Day")
> from_time = models.**TimeField()
> to_time = models.**TimeField()
>

While creating the forms, take input from the user for the WorkingHours 
model. This way, the days of work will not be hardcoded, and user can 
select mutiple choices.

Sandeep

Re: settings and constants on a reusable app

[Thomas Rega]

Am 28.06.12 17:30, schrieb Marc Aymerich:

Hi,
I'm developing a reusable application and I'm having troubles with
constant values on settings.

Imagine that the reusable application comes with the following settings.py

# MY_APP/settings.py
from django.conf import settings
MY_CONSTANT = 'C1'
MY_OTHER_CONSTANT =  'C2'
MY_SETTING = getattr(settings, 'MY_SETTING', CONSTANT)


But for your project you want to override the default value of
MY_SETTING by MY_OTHER_CONSTANT. So you edit your project settings.py
and adds these two lines:

# Project settings.py

from MY_APP.settings import settings as my_app_settings
MY_SETTING = my_app_settings.MY_OTHER_SETTING


But this is going to fail because of the import order.

Is there any consistent way to handle this situation?

Thanks!

Hi,

what about the idea to overwrite these values via a 'local_settings.py' 
file?


An example can be found here: 
https://bitbucket.org/chris1610/satchmo/src/1255b19295c7/satchmo/projects/skeleton/settings.py


Good luck,

How to run a django app in a subdirectory alias

[Sven Grunewaldt]

Hi,

I want to run a simple test project in a subdirectory alias on our 
development server. The basic setup is an nginx with a location that passes 
everything in a subdirectory to the wsgi application.

Django obviously does not understand that it runs in an subdirectory alias, 
which completely destroys URL generation and parsing.
I could not find any prefix-like setting in the docs and my google fu also 
did not help that much... so I'm asking here instead.

The only thing I *did* find was the setting FORCE_SCRIPT_NAME which at 
least fixes the URL generation. (see: 
http://docs.webfaction.com/software/django/config.html#mounting-a-django-application-on-a-subpath
)
Sadly this does not fix the urlconf parsing, even though the mentioned site 
suggests that.

Is it possible to run a django application in a subdirectory alias and if 
so, how?

Thanks,
Sven

PS:
nginx config:
server {
location /fancyprojectname/static {
alias /srv/fancyprojectname/static;
}

location /fancyprojectname/ {
uwsgi_pass unix://var/run/uwsgi/app/fancyprojectname/socket;
include uwsgi_params;
}
}

Hi thomas, thanks :)

Yeah, actually I'm using a local_settings.py file, but at the end it
will be the same as using settings.py since local_settings.py is
imported by settings.py. :(

Redirect question

[ivanb]

I'm still learning django so please forgive if I write anything silly.

On my site I'm having something like: on url mysite/list/ I have list of 
something. On it I have link that leads to another view if you want to add 
new element to it let's say: mysite/list/add_item/ 

On that url I have form with some information that needs to be written and 
a file upload in the form. On form submit it actually goes to new view 
mysite/list/adding/ and there the needed work is done.

After the work is done I want to go back to the first url and view 
 mentioned. Thing is I would also like it to show a message up there about 
status of what happened, so I can't use redirect, and if I put 
render_to_response it actually shows the proper view with the appropriate 
message but url is not the right one, it keeps the 
mysite/list/adding/ (that is logical behaviour and I understand it) but I 
want mysite/list/.

I'm asking for a way to achieve this, do some work and redirect to some 
previous view with some context added. Also I would like you to point out 
if I did something here that could have been done in better way so I can do 
it right and learn for the future.

Also, I know it could be done with setting some get parameters for the 
redirect but I would like to keep the url clean if possible.

If you know please advise.

Thanks

Use the messages framework to add a message to the user when you process,

If you're using Class Based Views, you can use a mixin to achieve this.
Here's mine if you want to check it out:
http://stackoverflow.com/questions/5531258/example-of-django-class-based-deleteview/10903943#10903943(Scroll
Down to the Bottom)

This may be a bit advanced for you at the moment but it works really well
for me. You can ignore most all of the other code in that posting and just
focus on the MessageMixin. Also, see the documentation link posted by
Daniel Roseman. The messaging framework is the way to go for passing on a
"Success" or some type of a notification message.

Out of curiosity, what is it that makes your college servers

Until I saw this comment I was going to suggest you just host it
yourself on a static IP somewhere (or using PageKite to tunnel out if
you are stuck behind NAT), as it seems you should have very modest

javascript in django template not executed when request is sent via ajax

[Larry Martell]

I have a django template that has some javascript/jQuery code in it
that defines some keyup event handers. If a user goes to the URL
directly the javascript is executed, and the event handers all work
fine. There is also a field that they can type in that triggers the
same URL request to be sent via ajax. When they do this, it seems that
the html is rendered, but the javascript is not executed. I discovered
this by noticing that the page was rendered, but none of the
javascript event handers were being called. I proved this by adding:



alert('here we are');


to the template, and the alert doesn't show when the request comes
from ajax. But if I go to the URL directly it does.

Is this a known issue? Is there some way I can get my javascript code
to run to install my event handlers when the request comes from ajax?

TIA!

Upgraded to django1.4 and cms2.3.
I'm only still struggling with django-filer. What would be the advise?
Is a new version of filer expected soon? 
Or is the development-version enough for production?

Thanks Andy. Super cool, and pretty much just what I was looking for.

Re: javascript in django template not executed when request is sent via ajax

[Jani Tiainen]

It's known limitation of your ajax request and has nothing to do with
Django nor templates. Or well it might do.

Most of the javascript frameworks can extract script and inject it
correctly to current DOM. Since you mention jquery I guess that you're
using that for ajax queries so make sure that your $.ajax() has dataType
attribute to set as 'html'. It should (according to docs) parse script
parts correctly.

Re: javascript in django template not executed when request is sent via ajax

[Jani Tiainen]

I meant that if for some reason Django sends incorrect content type from a
view or something like that your javascript framework might guess
incorrectly your ajax request content type and not parse script tags.

Not really sure what you mean here. Are you saying this is a known
problem, and I should not expect it to work?

Yes, it does. The request is sent like this:

$.ajax({
url: url,
data: $form.serialize(),
dataType: 'html',
success: function (html, textStatus) {
$report
.html($('#report', html).html())
.css({
opacity: 1.0
});
style_preview_table();
}

And I have verified that all the non javascript portions of the
template are executed, but none of the javascript ones are.

Is there a way I can test to see if this is occurring?

advantages and disadvantages of Raw sql queries in django

i want to know pros and cons associated with running raw sql queries
over django's ORM .
googled it out but couldn find many useful links.

Re: advantages and disadvantages of Raw sql queries in django

[Mike Dewhirst]

I firmly believe in using the ORM for everything until i am forced to use  
handwritten SQL.


The main reason is transparency of intentions when the source is examined by  
a non-DBA. 

I want my code to be maintainable by other people and provably correct. I  
suppose you can unit-test code with embedded SQL but it adds an extra layer  
of complexity.


I could also argue against custom SQL because it contains business logic and  
i prefer to keep that all in one place, ie., in models in python code.


So the bottom line for me is to avoid it where possible.  Once everything is  
profiled and the last remaining bottlenecks are significant and cannot be  
removed unless I use custom SQL, that's when I'll do it.


Haven't gotten there yet.

I am not overriding, at least not deliberately.

django/contrib/comments/templates/form.html has:
{% load comments i18n %}
{% csrf_token %}

I render my form with:
{% render_comment_form for entry %}

I should note it did work when I first added it to the application.  It 
broke after I added pybbm.  I've since removed pybbm (it is maintained and 
broken), but comments
started getting csrf errors.

Re: advantages and disadvantages of Raw sql queries in django

[Jon Black]

Also, using ORM means you're less likely to be tied to a specific
database...or in other words, your hand-crafted SQL is likely to be
specific to certain databases.
