Django TCP socket communication
I am new to TCP socket programming. I have a django based server communicating with a microcontroller. Now, I want to implement TCP based socket on the server side in order to communicate with the TCP socket on the microcontroller. Can anyone give me an idea on how to do this ? What libraries should I use on my django server The microprocessor basically opens the socket every 5 seconds and sends a notification to the server. I on the server side should be able to read this and pump data back to the microprocessor using this socket which was opened by the microprocessor. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Adding context data to a TemplateView?
An additional point, if you want to be able to use the view more
generically (be able to pass in custom context from your urls.py), I've
done the following:
class StaticPageView(TemplateView):
context = None
def get_context_data(self, **kwargs):
context = super(StaticPageView, self).get_context_data(**kwargs)
context.update(self.context or {})
return context

Thanks for the quick reply. here's what I have:
selchecks=ctx.request.field_value("selItems")
myselchecks=','.join(selchecks)
assert False, myselchecks #print the value to the screen and stop
This bit of code raises a key error as follows:
KeyError: 'selItems'
The value of selitems is ['1', '2', '3', '4', '5']

Comments
the Django docs state that "Django's comments are all "attached" to
some parent object"...
I'm building a very simple django powered website with auth,
flatpages, and comments currently installed. I want to use the
comments so people can post testimonials which can then be displayed
on the site. What would I attach to using this form statement as a
starting point:
{% render_comment_form for [object] %}
ie what should the object be?

We plan on moving it to django but for now we just have python running on an in-house framework. there is a point in the code where i need to write a file... let's call it "myfile.txt". The directory i'm writing to most likely will not have any existing files inside. Therefore the dirname function won't work because I have no file to base it off of. the only known in this situation is the file should be written to home/sites/x/library where x is the domain name which also happens to be dynamic. I need to find the x part of the path which is the domain name (whatever.com, ie). I'm thinking that the only way to do this is to get the current URL being viewed but I can't figure that out. I think it has to be with os or urllib but I can't seem to find the answer. any help is greatly appreciated. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

perplexing form issue
Hi group. I have form on the right side of my website. It's a simple site consisting of a single template and utlizes flat pages. Now i can create content just fine and that is all working. The issue is that the form is not showing up when I view the site. I'm assuming that it is because something is awry with the urls or views. I think i've narrowed it down to the following question. How can I specify that the form show and work on each page in the website? I've tried the following in my urls.py file: (r'/$', 'myForm'), where myForm is my view what am I missing? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

html inserted into csv file
HI group. I'm using the python csv writer to drop a csv file
available for download/opening when a button is clicked on my site.
The code is shown here
myselchecks=selchecks
sql="select * from inquiries where inquiry_id = (%s)"
%myselchecks
ctx.request.write_header('Content-Type', 'text/csv')
ctx.request.write_header('Content-Disposition','attachment;
filename=contacts.csv')
ctx.request.write = ctx.request.write_content
writer = csv.writer(ctx.request)
c = ctx.request.db.cursor()
c.execute(sql)
writer.writerow([x[0] for x in c.description])
writer.writerows(c.fetchall())
This code drops all selected fields into a temporary csv file named
"contact.csv" so that it can be downloaded. However, the template
HTML is being appended after the last record in the csv file.
Is there any way to prevent this from happening?

tinymce help
hi. I'm using django 1.0 over at webfaction. I have the following
setup
/static (serves js, css, flash, images etc)
/www (my django app)
I have tiny_mce loaded to /static/js/tiny_mce/
I have followed the steps at this page:
http://code.djangoproject.com/wiki/AddWYSIWYGEditor
in this order:
1. Install tiny_mce on your server some where
2. create a textareas.js file (placed in /static/js/tiny_mce/)
3. created an admin.py file in my website located at www/learn/ as
follows:
from django.contrib.flatpages.models import FlatPage
from django.contrib.flatpages.admin import FlatPageAdmin as
FlatPageAdminOld
class FlatPageAdmin(FlatPageAdminOld):
class Media:
js = ('js/tiny_mce/tiny_mce.js',
'js/tiny_mce/textareas.js',)
# We have to unregister it, and then reregister
admin.site.unregister(FlatPage)
admin.site.register(FlatPage, FlatPageAdmin)
step3 i'm confused on. This is for newforms with flatpages per the
documentation. It is my understanding that django 1 uses newforms.
Why won't the admin show the tinymce in place of text areas?

great. however, i've got a problem.
When viewing the source below:
Yes
No
(Check for yes)
You can see the class is added to the LI element, not the UL. How do
i stick a class on the UL itself so I can format that list? I have
several like this on my form and they each need to be edited
independently in regard to their style.

required checkboxes issue
I have a problem with one of my forms in regard to a series of
checkboxes. They are displaying properly on the page with the right
values in the checkboxes. I have this set to REQUIRED in my form.
However, whether I check one box, or check them all, I still get this
message:
"Select a valid choice. That choice is not one of the available
choices."
My forms.py code for this form field is as follows:
Designations_Choices = (
('1','1'),
('2','2'),
('3','3'),
('4','4'),
)
Designations = forms.ChoiceField
(choices=Designations_Choices,required=True, label = "Gift
Designations", widget=forms.CheckboxSelectMultiple(attrs=
{'class':'designations'}))
Any ideas why this won't validate correctly even when 1/4 or 4/4 boxes
are selected?

I've got a form that is kind of working. It's very strange because only choice fields are being pushed to the form and the textfields are not visible.

time differences
I need to know the # of seconds between two dates for my django application. I believe this has to be done with straight python. I've read the py docs on time functions but it doesn't make sense to me. Can anyone help? Here's my situation: timea='11/15/2008 11:35 AM' timeb=datetime.now() How can I calculate the diff between timeb and timea in seconds? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Well I need to know the exact # of seconds from 2008-09-16 08:01:16
to now not from just a date to date. It has to be exact... does
this make sense. I was looking at this page
http://pleac.sourceforge.net/pleac_python/datesandtimes.html in the
"Converting DMYHMS to Epoch Seconds" section. I thought perhaps it
would be easier to just get the epoch seconds between this time, and
NOW() and subtract the two, however I keep getting an error locally in
my terminal window reading:
>>> import time
>>> import datetime
>>> t=datetime.datetime('2008-09-16 08:01:16')
Traceback (most recent call last):

time help (again)
ok day 7 and no luck. I really need help. I need to calculate the
difference between two dates, one pulled from the database, and one as
the NOW time. I'm hoping someone out there can help me and explain
the code to me. Yes I've read the docs but they don't make sense to
me thus the reason i'm asking for help. Thank you in advance.
the first date is pulled from the database and is in the format:
2008-12-01 22:02:59
the second date is the now time in the format: 2008-12-01
22:32:47.391200
I need to calculate the difference between the two dates in total
amount of seconds.
Here's what i've got so far:
ctx.locals.session_id=ctx.sesid()
c = ctx.request.db.cursor()
c.execute('''SELECT hit_date from tablename where session_id=%s
order by id desc limit 0,1''', (ctx.locals.session_id))
ctx.locals.lasttimestamp = c.fetchone()
hittime=ctx.locals.lasttimestamp
nowtime=datetime.datetime.now()
totalseconds=nowtime-hittime
Can anyone tell me how to do this in python. I'm coming from an asp
background where there is a built in function to determine this.

Hi everyone. I have checked and re-checked my path for my templates

Sites issue
Hi Group...
below you will see a code snippet which records a testimonial
submitted off of a form into the database. Here's my setup...
I'm hosting at webfaction with 3 instances of django running with 3
sites, 4 sites and 4 sites (only way I can avoid running over my RAM
allotment). The sites use flatpages and sites. This code is in each
website with the exception of the siteid it writes to the database.
The code submits fine to the database but the wrong siteid # is
recorded. Can you think of anything that might be causing this. In
this example below, I even have the siteid hardcoded in the section
where django actually saves to the database help greatly
appreciated...

MultipleChoiceField issue
Hi all. I'm using python2.5 / django .96x (yes i know - we're
upgrading soon). I have an issue with a multiplechoice field which I
can't figure out. Here are snippets
from the form:
# disaster choices previously defined
Disaster=forms.MultipleChoiceField (required=True,
choices=Disaster_Choices, label="Disaster(s)",
widget=forms.CheckboxSelectMultiple(attrs={'class':'multibox'}))
from the model:
Disaster = models.CharField (max_length=20,
blank=False,db_index=True)
from the view:
mydata = Record (
Disaster = CleanMe(request.POST.get('Disaster','')),,
Active = 0)
mydata.save()
Ok so here's what's going on There are 4 disasters which appear as
checkboxes on the form. This works great. When the form is
submitted, I run the form field through a little function called
CleanMe which strips out certain character combinations. I do an
assert here right before the mydata = line to view what was submitted
off of the form for the disaster options.
If I select Earthquake, Tornado, Hurricane, I would expect to pass in
EQ, TO, HU to the view. However, only HU is being passed to the
view. No matter how many I select, only the last option is being
passed.
I'm obviously not doing something correctly but can someone point me
in the right direction here?

Hi Karen -
thanks for your reply. I tried to do the following in the view:
Disaster=request.POST.getlist('Disaster','')
on the form i selected a, b and c:
when i submitted the form, I asserted the value and get this:
TypeError at /submit/
getlist() takes exactly 2 arguments (3 given)
Can you provide me an example of how I should be using getlist? I
don't see anything in the docs related to forms and getlist.
Regarding the form clean() method, i'm looking for it but it would be
a great help if you could point me in the right direction.

pre-populating multiplechoicefields with session data
Hi group. Please look at this view:
# this form runs the search mechanism
def DoSearchForm (request):
if request.method =='POST':
form=SearchForm (request.POST)
if form.is_valid():
try:
myuid=request.user.id * 1
except:
myuid=0
#form submitted passes validation so submit to database as
a valid search term record
mydata = SearchAttempt (
Terms = CleanMe(request.POST.get('Terms','')),
suid = myuid
)
mydata.save() #save to sarch_attempt table
# save items to session variables
request.session["Terms"]=request.POST.get('Terms','')
request.session["Iforand"]=request.POST.get('Iforand','')
request.session["Programelement"]=request.POST.get
('Programelement','')
request.session["Disaster"]=request.POST.get
('Disaster','')
request.session["Submissionmethod"]=request.POST.get
('Submissionmethod','')
return HttpResponseRedirect('/search/results/')
else:
return render_to_response('submit-search.html', {'form':
form}, context_instance=RequestContext(request))
else:# load form for first time
if 'Terms' in request.session:
form = SearchForm(initial={'Terms':request.session
['Terms'],'Iforand':request.session
['Iforand'],'Programelement':request.session
['Programelement'],'Disaster':request.session
['Disaster'],'Submissionmethod':request.session['Submissionmethod']})
else:
form = SearchForm(initial={'Iforand':'exact'})
return render_to_response('submit-search.html', {'form':
form}, context_instance=RequestContext(request))
This view is working perfectly except for one thing. If someone
completes the form, it saves the form options to a session and inserts
the term they searched for into the database. If they close their
browser and come back to the search form, I want their previous
choices to populate the form again. Terms and Iforand populate as
they should. Programelement, Disaster, and Submissionmethod are all
multiplechoicefield textbox lists and none of the previously selected
options are selected. Can you see what i'm doing wrong?

checkboxInput values
If i use the multiple Checkbox Input, It results in list of the items
which were selected.
My question is can you do the same thing for a single checkbox?
As an old ASP guy I'd do this:
I'm trying to do this in django by the following:
#...snip forms.py
el1_Choices = (
('EN', 'ENGLISH'),
)
el1=forms.ChoiceField (required=False, choices=el1_Choices,
widget=forms.CheckboxInput(attrs={'class':'multibox'}) )
The resulting HTML is:
As you can see there is no value. It is returning the following
error:
Select a valid choice. That choice is not one of the available
choices.
Even though I've got the form field setup to required=False.
What is the proper way to assign a value to a single checkbox? Am I
just stuck with boolean and true/false? That seems like a lot of
extra work on the back end.

trouble with template tag
Hi. I have the following template tag:
@register.filter(name='elementtotext')
@stringfilter
def elementtotext(string):
itext='Unknown'
if string=='DR':
itext='Door'
if string=='FL':
itext='Flooring'
if string=='FO':
itext='Foundation'
if string=='FR':
itext='Framing'
if string=='GR':
itext='Grounds'
if string=='HV':
itext='HVAC / Utilities'
if string=='MI':
itext='Miscellaneous'
if string=='RF':
itext='Roof'
if string=='WM':
itext='Wall Material'
if string=='WI':
itext='Window'
return itext
The purpose of the tag is to take a record set field value and return
the text equivalent of that value. My field name in this example is
tm.element.
I can print the raw code to the screen fine but I'm having trouble
running it through my template tag. Can someone tell me the proper
syntax?
I'm trying {% elementtotext tm.element %} and it errors out.
I'm using python2.5 and django .97 or thereabout.

executing raw sql results in traceback
hi gang. For various reasons i've decided to use a raw sql statement
in my view. Following the example located at
http://docs.djangoproject.com/en/dev/topics/db/sql/, I have a view
which looks like this:
def searchform(request):
from django.db import connection
...
# a massive sql statement is dynamically built here. called sqlall
(used below)
try:
#setup recordset
cursor=connection.cursor()
cursor.execute (sqlall)
tms=cusor.fetchall() #this will be pushed back to the template
except IndexError:
#nothing found so redirect to "no results page"
return HttpResponseRedirect ('/search/results/none/')
...
When I assert the sqlall variable, the sql statement executes
perfectly in phpmyadmin. However, Django throws the following
traceback:
not enough arguments for format string
I have no idea what this error means and why it's not working... any
ideas?

Re: executing raw sql results in traceback
there shouldn't be really. The client has a search form and due to the way they want the search done there are about 40 option checkboxes for filtering in about 5 categories. It would have been easier if a filter with IN could have been used but the way the search logic is setup that is not an option. An example of the sql query being used is like this: Select * from table_name where field1 like '%,BC,%' and field2='AR' and field3 like '%,CM,%' order by date_received desc" %s is not used in this statement. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

My apologies... I didn't see Alex's post. Google some times collapses
threads on me. Replacing % with %% seemed to work. It queries the
database and returns a dataset like this:
((6L, u'WI', u'ST', u'test3', u'test3', u'test3', u'test3', u'test3',
u'PR', u',EQ,FL,HU,', u'test3', u',AC,', u'test3', 1, datetime.datetime

( that is the value of tms=cursor.fetchall() )
I'm just not sure how to get the value of tms back up to my template.
I'm passing in the data but when i try to do {{tms.title }} for
example nothing prints.

Thanks for your informative reply. The reason that I chose raw sql is
that the search form itself has 40 option boxes which control results
in about 7 fields. I was looking at the filtering mechanism for
django db calls and it really wouldn't apply due to the way that the
database is structured (ie an IN filter wouldn't work for some of
these things.). That url you referred to is just what i'm looking
for. I'm an ASP programmer making the transition away from the dark
side and still have wobbly python legs so i'm not always 100% sure
what to search for. Thanks again.

clean data uniqueness question
hi gang i have a subclass on my form as follows:
class NewUrl (forms.Field):
def clean(self, value):
rs=WebPage.objects.filter(url_slug=value)
thislength=str(len(value))
if rs.count()!=0:
raise forms.ValidationError ('This URL is already in
use.')
if not value:
raise forms.ValidationError ('Please enter a url such as /
my-page/')
if len(value)>254:
raise forms.ValidationError ('254 Characters Max. The
current length is %s' % thislength)
return value
This checks to see if a url being added to the system is unique and it
works great. My question is this. If i load data to a form
(initial=) with an initial url, how can i check to see if the url
going back on an update is unique AND not for the current record?

Here's what i'm trying to do. I've got a module that allows us to add
new items and edit new items to the database. I was going to use a
url slug which has to be unique anyway, but that will not work for
this application. As a result i'm allowing users to enter a url path
(ie /whatever/this/page/is/) and it's being served up fine through a
middleware class I wrote to substitute for flatpges (it does more than
standard flatpages). In my form above I'm trying to find a way to
check and see on form submission if the url has been changed to
another URL which is in the database already and not for the current
record. That part I can handle. I think the key to this is getting
request.path into my form field subclass above so that I can get the
record id which is passed through the url.

ok i don't understand all this (django noob here) but i need to check
the url in a subclass that does specific validation, not in the view
which saves the form. Basically if they enter a URL and it exists in
the database for another record, I want it to raise a form validation
error and tell the user that the url is in the database for another
record. is there an easier way to do what is needed? I'm lost.

That's kind of what i was thinking... Here's what i have:
pg=WebPage.objects.get(
Q(body__icontains=delurl) | Q(blurb__icontains=delurl)
in theory that should be identical to "select * from webpage where
body like '%delurl%' or blurb like '%delurl%'"
I have two records. One has the value i'm looking for in the blurb,
the other in the body, so it should return 2.
I'm getting this traceback:
get() returned more than one WebPage -- it returned 2! Lookup
parameters were {}

Update: with a unique index on the database field it throws a nasty
integrity error. How do i prevent duplicates like this?

images do not upload
hi all.. using 1.0 w/ py 2.5 here. I have a problem with an
ImageField failing to upload the images. i've checked the perms on
the dir and they appear to be ok. Here are snippets of what i've got:
from models.py
pic = models.ImageField(upload_to='public/images/
bank_pics',blank=True)
from views.py
modbranch=Branch.objects.get(id=bra_id)
modbranch.pic = manage_cleantext(request.POST.get('pic',''))
modbranch.save()
from forms.py
pic = forms.ImageField(required=False, widget=forms.FileInput
(attrs={'class':'filebrowser'}))
a couple of questions.
I thought that the upload_to should be appended to the file name that
I upload when saved into the db field. Right now my db field just
shows testpic.jpg rather than assets/public/images/bank_pics/
testpic.jpg as expected. Am I mistaken?
Can you think of any reason that the image would not upload? I've even
got the form as a multi-part encode.

populating a dropbox with a directory listing.
Hi group. I need to pull a directory listing and populate a dropbox. I know how to do this with a queryset but how could i do it with something like this? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

ModelChoiceField queryset option
hi group
i'm trying to create a drop box that is populated with a distinct list
of values from a certain field (fieldname=page_plaque) in the table.
Here is what i have in my forms.py
class PagePlaqueModelChoiceField (forms.ModelChoiceField):
def label_from_instance(self,obj):
return obj.page_plaque
page_plaque = PagePlaqueModelChoiceField
(queryset=WebPage.objects.filter(page_plaque!=''),
empty_label='Choose',required=False, widget=forms.Select(attrs=
{'class':'dropbox'}))
this is not working and errors out with:
'bool' object is not iterable
Is this possible and if so what am i doing wrong? Can I pull a
DISTINCT list of values for that field?

Is there a way to pull a distinct list? ideally i'd like it to return something like this pic1.jpg pic1.jpg pic1.jpg pic2.jpg where the option value is the ID of the record from the table. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: ModelChoiceField queryset option
> Hi. > You should take a read on the queryset api, that would help you a lot > In the furture. For distinct values add .distinct() so you fx get > ...filter(...).distinct() > > ~Jakob Jakob - I've read the docs and know about distinct. The issue here is that a modelchoicefield returns the ID and then whatever you specify to populate the human readable value in the selection box. See my example above of what I am looking for. If i just use distinct, the record id is always used so it will always be distinct... or am i misunderstanding something here. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

querystring redirect
hi all... is it possible to do the following?
let's say the user types in the following url into their browser:
mysite.com/redirect/?http://www.newsiteout.com/whatever.asp
Is it possible to snag the redirect url after the ? in the url and
then use it to do a redirect? I've run into a situation where a
client has a need for an interim ("you're leaving our site") type page
before doing a redirect. I'm trying to make this as easy as possible
for the client.
is this possible? I'm reading the response docs but i'm not really
finding a good example.

help with excel exports
Hi all -
I'm pushing content to a template which i have built to properly
organize the data for an excel spreadsheet. I'm generating the
response in my view as such:
response = render_to_response("spreadsheet.html", {
'tms': tms,
})
response['Content-Type'] = 'application/vnd.ms-excel'
response['Content-Disposition'] = 'attachment;filename=biblio-
export.xls'
response['Charset']='UTF-8'
return response
This works great with one exception. It saves the file to the
person's last saved location... in my case it's the desktop, in other
cases it's /downloads etc
Is there a way to force the SAVE option so that when they click SAVE,
the user can determine where to put the file? My testing so far
indicates this is not browser independent
