Hello, I'm developing a web page in Django (using apache server) that needs to call a shell command to enable/dissable some daemons. I'm try to do it with
os.system(service httpd restart 1>$HOME/out 2>$HOME/error)
and this command doesn't return anything. Any idea how can i fix this?
| random_code | varchar(200) | YES | UNI | NULL | |
MyTable.objects.filter(random_code = None)
Is this correct? Will this SELECT where there is no random code set? Above is my table.
"8,5,,1,4,7,,,,7,,1,9,3,6,,,8,6,3,9,,2,5,4,,,,,3,2,,,7,4,1,1,,4,,6,9,,5,,,,5,,,1,,6,3,,,6,5,,,,7,4,,1,7,6,,,,8,,5,,,7,1,,3,9,"
I'm doing a programming challenge where i need to parse this sequence into my sudoku script.
Need to get the above sequence into 8,5,0,1,4,7,0,0,0,7,0,1,9,3,6,0,0,8.........
I tried re but without success, help is appreciated, thanks.
I'm trying to use a third party application located here:
git://github.com/Star2Billing/django-audiofield.git
I'm using Aptana Studio as my IDE. I created my project and then I clicked on the project and imported the app from the github location. It looked like it imported. I wanted to check that it imported properly before beginning any real coding so I performed manage.py validate.
I got a message that stated: "No module named audiofield". I added the app to my Installed Apps settings and followed the installation instructions.
I'm not sure if I'm importing it incorrectly. Also, I'm using virtualenv in Aptana. I'm not sure if this may have added to the problem.
Please help.
In a class method, I can add attributes using the built-in function:
setattr(self, "var_name", value).
If I want to do the same thing within a module, I can do something like:
globals()["var_name"] = value
Is this the best way to do this, or is there a more pythonic solution?
I have a model called "Activity" in my django app. in the admin interface, it appears on the screen as "Activitys". how can I override the label on the admin page to make it "Activities" instead?
I see in the archives how to do this for a field, but not for a model itself. thanks!
This is probably a really silly question but, given the example code at the bottom, how would I get a single list that retain the tuples?
(I've looked at the itertools but it flattens everything)
What I currently get is:
('id', 20, 'integer')
('companyname', 50, 'text')
[('focus', 30, 'text'), ('fiesta',
30, 'text'), ('mondeo', 30, 'text'),
('puma', 30, 'text')]
('contact', 50, 'text')
('email', 50, 'text')
what I would like is a single level list like:
('id', 20, 'integer')
('companyname', 50, 'text')
('focus', 30, 'text')
('fiesta', 30, 'text')
('mondeo', 30, 'text')
('puma', 30, 'text')
('contact', 50, 'text')
('email', 50, 'text')
def getproducts():
temp_list=[]
product_list=['focus','fiesta','mondeo','puma'] #usually this would come from a db
for p in product_list:
temp_list.append((p,30,'text'))
return temp_list
def createlist():
column_title_list = (
("id",20,"integer"),
("companyname",50,"text"),
getproducts(),
("contact",50,"text"),
("email",50,"text"),
)
return column_title_list
for item in createlist():
print item
Thanks

Starting from an Html input like this:
<p>
<a href="http://www.foo.com">this if foo</a>
<a href="http://www.bar.com">this if bar</a>
</p>
using BeautifulSoup, i would like to change this Html in:
<p>
<a href="http://www.foo.com">this if foo</a><b>OK</b>
<a href="http://www.bar.com">this if bar</a><b>OK</b>
</p>
Is it possible to do this using BeautifulSoup?
Hello,
Im using Django 1.2.3. I have login functionality in my site using django.contrib.auth.views.login. The user is able to login after entering correct username and password. But, form.has_errors is not working i.e. if the login credentials entered are incorrect i dont see the error message. My login.html in templates/registration is as follows :
<html>
<head>
<title>Login</title>
</head>
<body>
<h1>User Login</h1>
{% if form.has_errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
<form method="post" action=".">
{% csrf_token %}
<p><label for="id_username">Username:</label> {{ form.username }}</p>
<p><label for="id_password">Password:</label> {{ form.password }}</p>
<input type="hidden" name="next" value="/" />
<input type="submit" value="login" />
</form>
</body>
</html>
Any way to fix this problem?
Please Help
Thank You.
What I wanted is printing out 5 dots that a dot printed per a second using time.sleep(), but the result was 5 dots were printed at once after 5 seconds delay.
Tried both print and sys.stdout.write, same result.
Thanks for any advices.
import time
import sys
def wait_for(n):
"""Wait for {n} seconds. {n} should be an integer greater than 0."""
if not isinstance(n, int):
print 'n in wait_for(n) should be an integer.'
return
elif n < 1:
print 'n in wait_for(n) should be greater than 0.'
return
for i in range(0, n):
sys.stdout.write('.')
time.sleep(1)
sys.stdout.write('\n')
def main():
wait_for(5) # FIXME: doesn't work as expected
if __name__ == '__main__':
try:
main()
except KeyboardInterrupt:
print '\nAborted.'
the following function parses a CSV file into a list of dictionaries, where each element in the list is a dictionary where the values are indexed by the header of the file (assumed to be the first line.)
this function is very very slow, taking ~6 seconds for a file that's relatively small (less than 30,000 lines.)
how can I speed it up?
def csv2dictlist_raw(filename, delimiter='\t'):
f = open(filename)
header_line = f.readline().strip()
header_fields = header_line.split(delimiter)
dictlist = []
# convert data to list of dictionaries
for line in f:
values = map(tryEval, line.strip().split(delimiter))
dictline = dict(zip(header_fields, values))
dictlist.append(dictline)
return (dictlist, header_fields)
thanks.
Hello all ,
I have a string like "SAB_bARGS_D" . What I want is that the string gets divided into list of characters but whenever there is a _ sign the next character gets appended to the previous one.
So the answer to above should be ['S','A','B_b','A','R','G','S_D']
It can be done by using a for loop traversing through the list but is there an inbuilt function that I can use.....
Thanks a lot

I am reading one line at a time from a file, but at the end of each line it adds a '\n'.
example:
line is: 094 234 hii
but my input is: 094 234 hii\n
I want to read line by linem but I don't need to keep the newlines...
My goal is to read a list from every line: I need ['094','234','hii'], not ['094','234','hii\n']
Any advice?
I am trying to use the ModelForm to add my data. It is working well, except that the ForeignKey dropdown list is showing all values and I only want it to display the values that a pertinent for the logged in user.
Here is my model for ExcludedDate, the record I want to add:
class ExcludedDate(models.Model):
date = models.DateTimeField()
reason = models.CharField(max_length=50)
user = models.ForeignKey(User)
category = models.ForeignKey(Category)
recurring = models.ForeignKey(RecurringExclusion)
def __unicode__(self):
return self.reason
Here is the model for the category, which is the table containing the relationship that I'd like to limit by user:
class Category(models.Model):
name = models.CharField(max_length=50)
user = models.ForeignKey(User, unique=False)
def __unicode__(self):
return self.name
And finally, the form code:
class ExcludedDateForm(ModelForm):
class Meta:
model = models.ExcludedDate
exclude = ('user', 'recurring',)
How do I get the form to display only the subset of categories where category.user equals the logged in user?
I've increased the font of my ticklabels successfully, but now they're too close to the axis. I'd like to add a little breathing room between the ticklabels and the axis.
I need to control a program by sending commands in utf-8 encoding to its standard input. For this I run the program using subprocess.Popen():
proc = Popen("myexecutable.exe", shell=True, stdin=PIPE, stdout=PIPE, stderr=PIPE)
proc.stdin.write(u'ééé'.encode('utf_8'))
If I run this from a cygwin utf-8 console, it works. If I run it from a windows console (encoding ='cp1252') this doesn't work. Is there a way to make this work without having to install a cygwin utf-8 console on each computer I want it to run from ? (NB: I don't need to output anything to console)
when using idle, I know you can reload a module if it's changed like this:
import foo
reload(foo)
if I only import part of a module, is there a way to reload it in a similar matter?
from foo import bar
How can I use the wx.ProgressDialog to time my method called imgSearch? The imgSearch method finds image files on the user's pc. How can I make the wx.ProgressDialog run while imgSearch is still running and display how long the imgSearch is taking?
Here's my code:
def onFind (self,event)# triggered by a button click
max = 80
dlg = wx.ProgressDialog("Progress dialog example","An informative message",parent=self, style = wx.PD_CAN_ABORT| wx.PD_APP_MODAL| wx.PD_ELAPSED_TIME| wx.PD_REMAINING_TIME)
keepGoing = True
count = 0
imageExtentions = ['*.jpg', '*.jpeg', '*.png', '*.tif', '*.tiff']
selectedDir = 'C:\\'
imgSearch.findImages(imageExtentions, selectedDir)# my method
while keepGoing and count < max:
count += 1
wx.MilliSleep(250)
if count >= max / 2:
(keepGoing, skip) = dlg.Update(count, "Half-time!")
else:
(keepGoing, skip) = dlg.Update(count)
dlg.Destroy()
