Re: Uploadfile form and CSS Style

[Russo]

Hi Kakar,

but i tried and there is not way to change the bottom style, see the 
html code



enctype="multipart/form-data">

{% csrf_token %}

{{ form.non_field_errors }}
{{ form.docfile.label_tag }} {{ form.docfile.help_text 
}}


{{ form.docfile.errors }}
{{ form.docfile }}




as it is a form there is no way to change style ¿?

Regards/AR

Re: Trouble with VirtualEnv on Windows

I suppose I was a little light on the details of how I setup the 
environment. I don't often setup a new environment from scratch so I used 
this post as the basis: 
http://slacy.com/blog/2011/06/django-postgresql-virtualenv-development-setup-for-windows-7/
 

The versions of each program I used / ended up with were:
   Python 2.7.3 (32 bit)
   Postgres 9.2 (32 bit)
   Setuptools 0.6c11 for Python 2.7 
   Psycopg2 2.4.5 for Python 2.7 (32 bit)

Trouble with VirtualEnv on Windows

[Joshua Russo]

This is probably a VirturalEnv problem as opposed to a Django problem but I 
was wondering if someone here could point me in the right direction.

I'm trying to setup clean environment for a demonstration of Django on 
Tuesday but I get the following when I try to setup the project within the 
virtual environment. You can see that if I just run python from within the 
virtual environment I do have access to the libraries, but if I try to use 
the django-admin.py script, the libraries aren't found. Any thoughts?

Re: Best practices for open sourcing a Django project?

[Joshua Russo]

Clifford, I have actually done this but the local settings files were 
merely used to override the production values. I think I like this way 
better for handling things like the database and the various path settings, 
though I'm not sure I will completely abandon the override mechanism either.

Thanks for the idea

Re: Best practices for open sourcing a Django project?

It sounds like you're saying that the open sourced project should be 
different from the production project. Am I reading that right?

Best practices for open sourcing a Django project?

[Joshua Russo]

I have project that I have been working and I was contemplating open 
sourcing it but I ran into a little hang up. How to handle the database 
authentication. The settings file obviously needs to be included but I 
don't want to advertise the production database login. How is this 
generally handled?

Also, are there procedures that need to be followed to "properly" open 
source a project, or is it really just choosing a licence and dubbing it so?

How do determine which {% load %} item is missing?

[Joshua Russo]

I've noticed that instead of generating an error, if a filter or tag is 
used that is not found in a {% load %} item, the include that contains the 
error is just skipped. Is there anyway to debug which filter/tag is failing?

How to specify a group by field set?

[Joshua Russo]

Is there a way to select a list of group by columns? 
The aggregation methods seem only apply to a single model but I want to use 
fields from different models to group by. 

select org.id as organization_id,
   dep.id as department_id,
   cat."catId",
   max(cat.name) as name,
   max(cat."nameDisplay") as nameDisplay,
   count(depItem.id) as itemCount
  from communitynetwork_listcategory as cat 
   inner join communitynetwork_listitem as li on
 li.category_id = cat."catId"
   inner join communitynetwork_organizationdepartmentitem as depItem on
 depItem.item_id = li.id
   inner join communitynetwork_organizationdepartment as dep on
 dep.id = depItem.department_id
   inner join communitynetwork_organization as org on
 org.id = dep.organization_id and
 org.active = True  
 where cat.name like '%service%' 
or cat."nameDisplay" like '%service%' 
group by org.id, dep.id, cat."catId"
order by org.name, dep.name, cat.order

This is what I tried to do with a QuerySet that didn't work:

OrganizationDepartmentItem.objects.filter(
department__organization__active=True
).filter(Q(item__category__name=searchValue) | Q(
item__category__nameDisplay=searchValue)
).order_by('department__organization', 'department__name', 
'item__category__order'
).values('department__organization', 'department', 'item__category'
).aggregate(Max('item__category__name'), 
Max('item__category__nameDisplay'), Count('item'))

Query exclude via model_set property?

[Joshua Russo]

I have a 3 table solution

class Organization(models.Model):
name = models.CharField("Organization's name", max_length=100)

class OrganizationDepartment(models.Model):
organization = models.ForeignKey(Organization)
name = models.CharField("Name", max_length=100)
contacts = models.ManyToManyField("Contact")

class Contact(models.Model):
organization = models.ForeignKey("Organization", blank=True, null=True)
name = models.CharField("Contact's name", max_length=100)

I want to create a list of contacts within an organization and not in a 
given department. The problem is that it looks like I can't use the 
contact.organzationdepartment_set in an exclude. Is that correct?

Is there any particular reason why it's assumed you won't be performing a Max on a CharField?

[Joshua Russo]

Is there any particular reason why it's assumed you won't be performing a 
Max on a CharField? 

I tried to create the following QuerySet:

Document.objects.filter(documentType=1, 
event__eventType=3).annotate(event_date=Max('event__start_date'), 
subcommittee=Max('event__subcommittee__name')).order_by('subcommittee', 
'event_date')

I enforce this particular documentType to occur only once per Event, but in 
reality the Document - Event relation is many to many. That is why I 
performed a Max on the to go from Document to a FK relation of Event.

I really only ask out of curiosity. As far as SQL goes, this is completely 
legit and I plan on modifying Django and submitting a patch. (Unless there's 
a compelling reason not to)

Re: Alter the list of fields returned by a queryset without turning them into strings?

[Joshua Russo]

So, how I actually solved it was even a bit different:

Document.objects.filter(documentType=1, 
event__eventType=1).annotate(Max('event__start_date')).order_by('event__start_date__max')

I had to use the Max function because the relationship is actually a many to 
many. Even if it was just a standard foreign key this is still an option, 
and it eliminates the problem of re-querying if you later decide to use 
other fields.

Alter the list of fields returned by a queryset without turning them into strings?

[Joshua Russo]

I have 2 tables, document and event. I want to retrieve the document url and 
the event date but it seems like I can't do this in a single query set and 
that is then used directly in a template. This was my first thought:

context = {
'minutes': Document.objects.filter(documentType=1, 
event__eventType=1).values('documentFile', 
'event__start_date').order_by('event__start_date')
}

with the template looking like 

{% for scm in minutes %}
 {{ 
scm.event__start_date|optTimeShort }}
{% endfor %}

The problem is that the values() command turns the FileField into a string.

If I remove the values() command I can access the event through event_set 
but it's not clear to me how to access the one and only event in the set 
within the template.

Do I just need to do a little more pre-processing in the view or can I 
accomplish what I'm trying to do?

I know you can run multiple admin sites, but the only reason I can see for 
doing it is to have a full admin and other customized admin sites for

CSS question

[Joshua Russo]

I know this is a bit off topic but I know this place is full of very 
helpful intelligent people. :o)

Ok so I have an html block (div, p, doesn't matter what kind), and I fill it 
with a label and an input text field. The input is always larger than the 
label (rightly so), but the label is always aligned to the top of the block. 
I want to center the label in the block but for the life of me, I can't 
figure out how.

Any ideas on how to fix it or where to go to get an answer?

Re: Best approach to handling different types of Users

[Joshua Russo]

Things will break in the sense that, if you add another app that accesses 
the User model they will only see the original implementation. They won't 
get your subclass. Other than that, other apps that use the User model 
should "work" just fine.

Unless I'm missing something, and in that case someone can kindly correct 
me. :o)

DB based translations?

[Joshua Russo]

Ok, I've been looking into the different database based translation 
solutions out there and I can't find what I really had in mind. I need to 
have non-technical people easily update the translations. So I wanted a 
solution where I could create an interface to ease the process.

One problem is that none of the solutions seem to talk about translating 
static text. I'm thinking I need to create a site_content table to handle my 
static text translations and then use one of these solutions against it. 

If this is an appropriate solution, what are people's experience with the 
different database driven translation solutions? I tried 
django_multilingual, and django_multilingual_ng but they seemed to have 
issues with South. (Of course that was a few months back and I can't 
remember the exact problems I was having.) I'm now looking at 
django_modeltranslation, but none of these products really give the 
impression of being production worthy.

I'm willing to give them a shot because I need something and it's small 
enough project that I can take a little more risk. What are people's 
experience with them?

Thanks in advance
Josh

I need help with reverse and url patterns

[Joshua Russo]

I setup this patter in url.py

url(r'^events/(?P\d{4})/(?P\d{2})/$', events, 
name="eventsMonth")

in my template I have this tag

{% url eventsMonth year=month.prev.year month=month.prev.month %}

but I keep getting 

Caught NoReverseMatch while rendering: Reverse for 'eventsMonth' with 
arguments '()' and keyword arguments '{'month': 7, 'year': 2011}' not found.

I traced the problem into the reverse() code and the logic goes all the way 
to the end, when the following statement from line 325 of 
core/urlresolvers.py fails and I can't figure out why

if re.search(u'^%s' % pattern, candidate, re.UNICODE):

The pattern is 
'events/(?P\\d{4})/(?P\\d{2})/$'
and the candidate is 
u'events/2011/7/'

Why doesn't that regular expression match? What am I doing wrong?

My models.py was getting too large so I tried to split it into

from appName.models.andSoOn import *

All of my imports still work but the queries are now looking for 
models_someTableName instead of appName_someTableName.

Re: How to test form values in a template? (simplified)

[Joshua Russo]

It's more that I want to have different ways of displaying the same form 
field. I want the text field to be on the same line as the checkbox when 
it's an input field and below it when it's displayed as a textarea. There's 
also the point of changing the required setting of the same field based on 
if the checkbox is selected or not. 

I guess what I'm trying to get at is, how should I access these values to 
determine the display and validation. If I don't use my method I will have 
to test for both the boolean value and the string value 'True' instead. 
That's what I'm trying to avoid.

How to test form values in a template? (simplified)

[Joshua Russo]

I realize that I went from too little information, to too much information 
in the previous post, so this is an attempt to find a middle ground.

What I'm building is the ability to have a list of checkable options, and 
depending on the setup for a give option it may have a text field to enter 
additional information. This text field can be either displayed as a single 
line text input or a multi-line textarea. 

My problem is that I want to have these different setup values available to 
control the validation and display of the form, but there doesn't seem a 
consistent way to test the values. When the form is POSTed back and isn't 
valid, the value out of the BoundField's value() metod for BooleanFields is 
a string, where it's a actual boolean on the initial creation of the page. I 
understand why this is, it's pulling from the POST data instead of the 
initial data. 

The way I over came this was to add a to_python() method to the BoundField 
class in django/forms/forms.py:

def to_python(self):
return self.field.to_python(self.value())

Below is what I'm doing. I'm using the new to_python() method are in the 
__init__ of the form, the save logic of the view, and the template at the 
end. I left out the CreateItemsSection() function that builds of the 
listItems dict because its convoluted. The listItems structure is in a form 
that's easily looped through in the template and the function creates (on 
the initial load) or inserts (on POST back) the forms of the formset. If it 
would be helpful I can post it but I think there should be enough 
information here.

Is there a better way to accomplish what I'm doing with the to_python() 
method? 

# Form class 

# I use the self["multiLineInfo"] pattern instead of 
self.fields["multiLineInfo"] 
# because the former gives a BoundField which merges the Field and the 
# post/initial data

Re: Best practice when testing form values in a template?

[Joshua Russo]

Ok, I apologize. Here is a fuller representation of what I'm doing. I had a 
hard time figuring out how much was enough versus too much. This is 
simplified, but I think it represents what I'm trying to do. For instance, 
don't pay too much attention to the save logic in the view, I haven't 
actually really worked on it much yet.

To restate my scenario, I want to carry information in hidden fields of a 
form that determine how the form is displayed and functions. I realize I do 
have access to the self.Initial values in the form itself but I don't think 
that there's easy access to those values in the template. The value that I 
want seems to be the value() method of the BoundField, but run through the 
to_python() method of the field. I actually solved this by adding a 
to_python() method to the BoundField that does just this, but I would like 
to solve this without modifying the Django code. The samples below do not 
reflect my added to_python() method.

# Form class (I use the self["multiLineInfo"] pattern instead of 
self.fields["multiLineInfo"] 
# because the former gives a BoundField which merges the Field and the 
post/initial data)

Best practice when testing form values in a template?

[Joshua Russo]

Ok, so I've created a fairly simple form:


class OrganizationItemForm(AuditModelForm):
selected  = forms.BooleanField()  
extraRequired = forms.BooleanField(widget=forms.HiddenInput)
multiLineInfo = forms.BooleanField(widget=forms.HiddenInput)

def __init__(self, *args, **kwargs):
super(AuditModelForm, self).__init__(*args, **kwargs)
if self["multiLineInfo"].value():
self.fields["descr"].widget = 
forms.Textarea(attrs={"class":"descriptionEdit"})
else:
self.fields["descr"].widget = 
forms.TextInput(attrs={"class":"itemDescrEdit"}) 
self.fields["descr"].required = self["extraRequired"].value()

class Meta:
model = OrganizationItem

I use this as a single checkbox entry that could optionally have either a 
single line edit, multi-line edit, or no text box at all

The applicable section of the template looks like this:



{% for item in cat.items %}
{{ item.form.selected }} {{ item.label }}
{% if item.form.extraRequired.value or item.descrLabel %}  
{% if item.form.multiLineInfo.value %}

{% else %}

{% endif %}
{{ item.descrLabel }}
{% if item.form.multiLineInfo.value %}

{% else %}

{% endif %}
{{ item.form.descr }}
{% else %}
{{ item.form.descr.as_hidden }}
{% endif %}
{{ item.form.extraRequired }}
{{ item.form.multiLineInfo }}

{% endfor %}
 

Keep in mind, this is a work in progress. I've not integrated the error 
output yet. Right now my problem is that if I simply click submit to test 
all of the error conditions, the value of the hidden fields is a string. 
This seems to be because to_python is only called for the cleaned value. The 
cleaned data is only available after the form passes validation.

What is the best practice for carrying data like this in a form and using it 
in the templates to govern conditionals?

Re: Extending the ManyToMany relation, maybe a bad idea

[Joshua Russo]

Ya, sorry, I was just getting frustrated because I was taking longer than I 
wanted to implement this. The formset is what I ended up with. The tricky 
part is still that I want a defined list of options in the formset, so I 
can't just make it a model formset. I haven't worked in Django in a while 
and it just takes a little bit to get my mind around what the options really 
are.

Re: Extending the ManyToMany relation, maybe a bad idea

[Joshua Russo]

Ok, so I can retrieve this extra data in the __init__ of the model form, but 
it seems like I will need to skip all of the cleaning and automatic 
validation of the form; because the data, to be displayed with the 
associated checkbox will have to be included with the items field in the 
OrganizationForm and fields and form names need to have a one to one 
relationship. 

I keep thinking I'm doing something wrong here. From the lack of responses I 
feel like there is no real good way to handle a group of options with 
additional relational data.

Re: Extending the ManyToMany relation, maybe a bad idea

[Joshua Russo]

My problem is that I have multiple values and I need to associate the list 
of extra fields with selected relations for the ManyToMany relation. Below 
is a simplified version of what my setup is. 

I want to create an edit form for Organization, but I'm struggling with how 
best to save (and re-retrieve for display) the descr field in 
OrganizationItem. I don't see how adding fields to the OrganizationForm will 
accomplish this.

# Models

class Organization(models.Model):
name  = models.CharField("Organization's name", max_length=100)
items = models.ManyToManyField(ListItem, through='OrganizationItem')

class OrganizationItem(models.Model):
organization = models.ForeignKey(Organization)
item   = models.ForeignKey(ListItem)
descr  = models.TextField("Description", blank=True)

class ListItem(models.Model):
name = models.CharField("Name", max_length=200)
order= models.IntegerField("Order")
extraInfo = models.BooleanField("Requires extra information")
multiLineInfo = models.BooleanField("The display should use a multi-line 
edit box instead of a single line edit")
descrLabel= models.CharField("Extra information label", 
max_length=50,
blank=True)

# ModelForm

class OrganizationForm(ModelForm):
class Meta:
model = Organization

Re: Extending the ManyToMany relation, maybe a bad idea

[Joshua Russo]

I am using the through keyword. I'm just trying to figure out the 
most efficient way to create a form field and widget to update the data.

What I'm struggling with is how a ManyToMany field with an intermediate 
table containing extra fields fits into the ModelForm saving. I'm just not 
sure where to save the extra field data, how best to collect it in the form, 
or how I would handle re-retrieving of the extra fields. The only  thing 
I've created so far is an extension of the ModelMultipleChoice field that 
creates a custom choices structure and an accompanying widget that extends 
CheckboxSelectMultiple. This will display the structure, but what's the best 
practice here for saving and re-displaying?

Extending the ManyToMany relation, maybe a bad idea

[Joshua Russo]

Ok, so I've created a structure of selectable properties, that for the most 
part is a straight forward many-to-many relationship. What I've added is a 
character field in the relationship table that should conditionally display 
based on the setup of the property being selected.

What I wanted to do was create a complex CheckboxSelectMany widget and 
supporting form and model fields, but once I got into the saving, deletion, and 
retrieval in the related field model fields, it looked like too much of a 
rewrite.

My current thought is to do each checkbox / conditional field combination as an 
individual form. Though I'm not sure if this is the best way to go about it 
either, because I don't see any real automated way to do this; short of 
retrieving all of the checkbox options and creating the form instances myself. 
I'm not opposed to this, I just want to make sure I'm not re-inventing the 
wheel. 

Any suggestions?

*light bulb* I forgot about my development vs production settings. I was

Re: Trouble overriding registration templates

[Joshua Russo]

Cool, thanks for the confirmation. 

I do have my template directories explicitly listed in TEMPLATE_DIRS. I even 
made sure that my app's templates came before the admin templates, but for 
some reason it's not picking up my /registration/logged_out.html and the 
others that show up in the admin's templates/registration directory. My 
/registration/login.html works just fine.

I'll try playing with the order of the installed apps and see if that makes 
any difference.

Nope, still no dice. Below is what I did. I modified the worker() function
from one of the Stackoverflow examples. Let me know if I'm using flush
properly. Keep in mind that everything you see here is already running in a
separate thread from the wxPython GUI so I can update the GUI while all my
tests run in the background.

Tried that too and even putting the reading of them in their own thread as
someone else suggested on Stackoverflow. I just can't find anyway to capture
stdout in real-time from Popen. The problem is that everything uses
readline() that buffers the output.

http://stackoverflow.com/questions/874815/how-do-i-get-real-time-information-back-from-a-subprocess-popen-in-python-2-5
http://stackoverflow.com/questions/2082850/real-time-subprocess-popen-via-stdout-and-pipe

The way I got it to work with out Popen is to use a text box control as the
stdout object. This works great, utilizing the object's write() method.

The problem with Popen is that it expects the stdout object to have a
fileno() method also, which the text box control does not have. So I tried
extending the text box to add the fileno() and had it return 1 like the
standard stdout, but still no dice. I didn't let the process (unit tests)
finish but it definitely was not giving real time output, through it did
accept the control with the fileno() method added. It really seems like that
should have worked and I may have been able to dig further into Popen to
make it work but I figured that I had spent too much time on it as it was.

If anybody has more suggestions I'd love to hear them.

The problem is that it waits for the process to end to output
anything. Unless I was doing something wrong, but I think I was doing
just what you describe here.

Ok, so it appears that (in Python 2.5 at least) there is no way to capture
the stdout of subprocess.Popen(). I've tried many different suggestions from
questions that have already been posted to Stack Overflow and everything
either buffers until the end of processing or just plain doesn't work.

So I dumped Py2exe and went back to using
django.core.management.call_command() and everything works like a dream.

In case you care.

Python question about subprocess.Popen() and stdout

[Joshua Russo]

I'm creating a wxPython application that the client can run to make
sure the installation stack is functioning properly. I want to include
the unit test processing in this application but I've run into some
difficulties. An additional wrinkle I threw in was that I am using
py2exe so they don't also need to install wxPython, we'll see if that
will actually work or not.

It seems like the most appropriate thing to do is to use
subprocess.Popen() to trigger "manage.py test --noinput". The problem
I am trying to solve is that this runs for a while and I want to
display the stdio output into a text box on the window.

I had this working using django.core.management.call_command but
creating the exe broke the pathing within Django and even some Python
libraries (thus dumping py2exe could be what I need to do).

The problem with switching to Popen is that it expects a file type
object with a fileno() method. The file class cannot be extended in
the stdio instance because you can't write back to the __class__
property. I guess what I need to know is how do I mimic stdout? Stdout
doesn't output to a file, but it still uses the file object. It seems
like I want to open a file object onto a Nul output. Can this be
done?

Thanks
Josh

Generic web-dev question: Best way to do a processing page?

[Joshua Russo]

This is mainly just curiosity at the moment. How do you create a
"processing" intermediate page, like you see on travel sites when they are
looking for the rates? I would always avoid this if at all possible, but
sometimes you have a process that takes longer than usual.

I've been looking around the web and I am not coming up with many examples.
So far I have only found one.

http://blog.ysatech.com/post/2010/02/06/ASPNET-redirect-a-web-page-with-AJAX-loading-indicator-image.aspx

Is that pretty much how it's done?

Re: Django Admin: DateField (Year and Month) only

[Joshua Russo]

I don't have an example of a date field but here is an example of how I
extended the Decimal field in making a Currency field.
http://www.djangosnippets.org/snippets/1527/

<http://www.djangosnippets.org/snippets/1527/>In the description there are
also links to the entire series of objects, including an input widget. That
should get you started on the concept of extending fields and widgets.

I think your best bet is to create a view to logically combine the tables in
the DB. You can then use the following link that I just stumbled on my self
in another thread on this list. It describes a method for accessing views
via a model.

Without the code from your view (and possibly the template) it's

I'm not sure I completely follow, but user.report_set only gives you reports
for the associated user, and it seems like that is what you want. You don't
need any further filters or excludes.

For future reference:
exclude(user_id__ne = user.id)
is the same as
filter(user_id = user.id)

Re: multi-db vs. data warehouse

[Joshua Russo]

I've never used Elixir so I can't really comment on the pros and cons.
With my personal experience I would go with an ETL and copy the desired data
directly into your ordering system. Just keep in mind that these new tables
should stay read-only as far as the ordering system goes. The data would be
there solely for ease of reference.

It really depends on where your skills lie. Play around with Elixir and see
if you can get what you need out of it. I see only two things to keep in
mind with Elixir and/or muti-db.
1) You won't be able to create real foreign keys because they are in
different physical systems. Though you can still create columns in the
ordering system that hold the primary keys of the other systems.
2) You won't be able to do real joins. You will have to query each system
independently. And yes this will still be the case with the multi-db support
when it is in place. Of course you will be able to intelligently build the
queries based on the dataset in the ordering system.

Re: multi-db vs. data warehouse

[Joshua Russo]

No one is recommending multi-db because it's not done yet.

I'm not sure I understand exactly what you mean by "creating new order and
order_item data with keys to data in the warehouse" but that doesn't sound
like a recommended approach.
A data warehouse (in my opinion) should be read only and no other system
should need to know about it. An important concept to keep in mind with a
warehouse is that it is never the originator of the base data (it may create
new computations of the data but it's always based on data from other
systems). As such it is for reporting purposes only and no other system
should treat it as the system of record.

If you need to link one order item to other data in the warehouse it should
only either be done in the warehouse or between the systems outside of the
warehouse. It sounds like you want to modify the order entry application to
reference data in other systems and still display the data in the order
entry app. If this is the case the only solution I would implement is
between the two existing systems.

As far as OLAP goes, it's not mutually exclusive from ER. It is simply a
method of extracting multidimensional data. An ER model can most certainly
be dimensional, you just need to integrate the proper timestamp structure.

Re: multi-db vs. data warehouse

[Joshua Russo]

I have many years of database design experience and it sounds like you are
getting lost in terminology.
I would start out with a set of tables in the warehouse that mirror the
existing data. In these tables you can either wipe and reload each time, or
create a mechanism to track each individual load.

You can then simply write your application against these tables or if you
feel adventurous you can add a more unified set of tables with linking
foreign keys and such and have your process also update the cleaner/more
unified data set. This second part get's tricky and takes practice to know
you have a good structure. You will also have to track changes, additions,
and deletions. If you want some help or advice I would be happy to take a
gander at your structures to show you what I might do. Feel free to email me

Re: multi-db vs. data warehouse

[Joshua Russo]

The multi-db branch is just now in the process of being baked into the core
and from what I can tell it's not quite done yet. Even when it is completely
done I would recommend the data warehouse approach. I view the multi-db
functionality more as a last resort, where you really don't have an option
to merge the data. It adds a lot of complexity so if you can do without I
would recommend an alternative.
Just my 2 cents

I'm not seeing a menu block in the base.html, so my guess is that it doesn't
know where to display the block. From my experience you can think of
template files as falling into two different categories. The base file that
lays out all of the bocks and the overall flow of the template, and
templates that inherit from the base file and override or extend those
blocks.

HTML / CSS question

I want to apply style to a block of text in the middle of a sentance without

 tags with a class property. My big fear is that the tags will

What JavaScript framework do you use and why?

[Joshua Russo]

I've been happily using JQuery for a while and was wondering why people use
the frameworks that they do. I want to see how other's get flexibility and
efficiency (cool widgets and good response time) out of JavaScript.
For example: The current project I'm working on I've created a visual
display of a timeline using CSS and transparent PNGs and use it allow users
to visually manipulate date ranges. I ended up creating a custom JavaScript
object to represent each value/date range to centralize manipulation logic,
initialized on page load from data provided in page creation. The objects
generally end up being just a bunch of references to the objects on the page
to be manipulated, in addition to the logic. I use JQuery to create each
reference and then thus also for the manipulations themselves.

This is usually the extent of my use of JQuery and I'm wondering if I'm
missing something in other frameworks that may make my life easier in tasks
like this.

Thanks for your insights.

You can access the images via moves.images_set.filter()...

That is kind of strange. I vaguely remember having a similar problem though
I don't remember how I solved it, though I did solve it, so it is possible.

As far as pdb, that is what I'm actually using at the moment. I just use a
text editor and run manage.py runserver from a batch file. When it hit's a
pdb.set_trace() it will drop you into a Python comand prompt with complete
variable context of the current point in the application, in the console
window starting for manage.py. So you can inspect and try logic real time
basically. It's really powerful and I would definitely recommend looking
into it.

Some day I might actually start reading a little better. You are doing
things properly. Is it stopping at the first line in the manage.py file when
you debug?

It may be the way you are running the program from NB. There are 2
buttons, Run Main Project and Debug Main Project. Make sure you are
using the second. It should automatically break on the very first line
of code (at least it did in 6.5), where you need to hit continue to

You can use the verbose_name properties in a Meta class in your model. Just
keep in mind you will need to use the lazy translation function.

http://docs.djangoproject.com/en/dev/topics/db/models/#id3

section for Lazy translations)

Gotcha, that's perfect. Thanks

Just one other thing. I was under the impression that x = u'' is equivalent
to x = Unicode(''). Is that not correct?  Seeing as you seem to be
indicating a difference between the unicode object and a literal.

Could you expand on this? I know that the Unicode string object has
different methods than standard String, but are there other scenarios where
a unicode literal could cause problems?

String encoding question

[Joshua Russo]

I was working through some regression tests and saw a scenario I thought
wasn't allowed/recommended. I was under the impression that if you specified
UTF-8 encoding at the top of the file you where not suppose to use u
decorated unicode static string. So instead of u'prédio' I use 'prédio' in
files where I specify the encoding in the file.
Now in regressiontests/admin_views/models.py I see u'¿Chapter?'. Does it not
matter if I use the u decorator on static strings with the encoding
specified? I was initially told that it could create problems.

Thanks
Josh

The way I have handled this in the past is to create a simple app that you
can run from the command line. I had it check a table that was updated with
the list of emails to send and set it up as a scheduled task (cron job) for
every 20 minutes or so.

And to perform the unicode out correctly the string in the body of your
method needs a u decoration infront of the string to indicate unicode.

return u'%s' % (self.name)
