Inline-edited items that are empty should be ignored during add processing. There was a problem at one point where entirely blank items were being flagged as validation errors, but that has been fixed. I'm don't recall ever seeing problems with entirely empty items being constructed. Could you give details of your models and what behavior you are seeing (I'm not sure if you are getting validation errors for blank items or spurious all-blank items added to the database?). Maybe check trac for reports of problems like what you are seeing. I haven't been able to keep up to date for a few weeks, but had been running on newforms-admin without running into what it sounds like you are reporting, so it's either something specific to your models or perhaps something that has changed recently.

The best way to prevent this is to make AJAX'y submissions in the background as they work, basically writing the application interface in JavaScript. It's an ugly job to code, but it can help save page-fulls of lossage. FireFox has similar behavior with control+W, but I believe if it's something you really want to prevent, you can bind it to a NOP to prevent it from occurring.

A short dig in the c.p.l archives found the link I had seen: http://wiki.wxpython.org/Printing Again, that was for printing to a printer attached to the server, rather than a printer attached to the web-client. Another option is to send the direct PCL yourself. I've hand-cranked printer drivers for a couple thermal printers (Zebra and Oneil) that had some basic page-layout functions that I could use. I just sent the printer-specific codes over the wire (IrDA, BlueTooth serial-profile, or serial-port in case) for fast and simple printing. If you just need a text dump that you can do via simple escape codes, this isn't a bad way to go. A bit of a pain to decipher printer manuals to get those codes...but feasible. At least for those two printers, the PCL is pretty straight-forward and well documented. -tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

DB query filter on member relations
I have a Model with two fields, a url and a title. If no title is given, it is initialized as the url (or at least the first 200 characters of the url). Is there a way to filter a DB query to get the rows that weren't initialized with a title? Something like MyModel.objects.filter(url__contains=self.title) I know that "self." there is mumbo jumbo. Any real solutions? If no good solution, I'm left making a new table or column to record these instances, or doing a crazy search on each row.

Always use absolute paths when creating symbolic links. Sounds like it should be something similar to "sudo ln -s /home/YOUR_USER/django-trunk/django /usr/lib/python2.5/site-packages/django" for you.

Re: newforms-admin replacement for core=True in inline models?
Thanks for the response. So what code do I need to add so that, when creating a new object, the admin doesnt try to create related fields that are left entirely blank?

There is a solution - it just hasn't been documented yet. The oldforms 'core=True' approach has been deprecated in favour of providing a checkbox that specifies that a row needs to be deleted. When you set up the FormSet, you can specify if rows are deletable; if they are, you get the checkbox on each row. This can be specified on a per-form basis, rather than messing up the model definition.

Re: Complex relationship for user profile
Hi Peter, I did a little more digging, and I'm not sure if my answer is in option 1 or 2... I am just using the automatic admin interface for my model at this point, with Django configured to use AUTH_PROFILE_MODULE = 'myapp.myuserprofile'. Is it safe to assume either model is saved first, or is there a reference to this behavior somewhere? 2nd question: does option 1 assume that I am using a custom form/template? If 'no', is it then possible to have the UserProfile model display the Users.email within it's form? And what might that look like? I'm trying to wrap my head around this new framework...still puzzled :S Thanks again, Aaron Peter Rowell wrote: Failing a response to that one must mean I'm asking for something that is undoable. Uh, this isn't McDonald's. Slow/no response does not immediately equate to undoable. It more likely means that people who might have answered the question were doing something else (watching the debate, coding, sleeping, having a life). Regarding your question: Depending on the dynamics of your app, you might investigate the following: 1. If the profile is updated first and you want to propagate some changes to the associated User record, try overriding the save() method for UserProfile, do your thing, and then call super(UserProfile, self).save() to finish. 2. If the opposite is true (User is changed and you want to propagate to UserProfile), avoid the temptation to hack contrib/auth/models.py. Instead, use signals. See http://code.djangoproject.com/wiki/Signals. See http://www.martin-geber.com/weblog/2007/10/29/django-signals-vs-custom-save-method/ for a discussion on the difference between custom save and signals. 3. Modifying the admin can be useful, but can the data only be changed through the form? If yes, then proceed. If no, then option 1 or 2 is a better way to capture the change, regardless of the source of the change.

best solution for a tight model
hi all I have a model made up of customers, project, works and invoices (sounds familiar? :-)) every project belongs to a customer, has many works. When I want to create a new invoice I would like to select a customer and a list of works that belongs to projects done for that customer and that do not recur in other invoices... something like this Work.objects.filter( project__customer__id = pcustomer).filter( invoiced_in__isnull=True) where pcustomer is the selected customer. now my first thought was to extend a django admin template and put some JQuery magic, but I thought it is a very common problem: I have a bunch of data related from some logic and not just model constrins. any suggestions? thanks SammyRules --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I am having this issue as well, I can user reverse('NAME') and it
shows the right url, but the {% url NAME %} fails. Also if I move the
entry down the list in my root url.py file it breaks the ability for
all urls listed above it to be traced with {% url %}
the following make it so I cannot use the {% url %} tag for any URL
(r'^modules/', include('apps.modular.urls')),
(r'^accounts/', include('apps.registration.urls')),
(r'^news/', include('apps.news.urls')),
(r'^blog/', include('apps.blog.urls')),
(r'^gallery/', include('apps.photos.urls')),
(r'^undo/', include('apps.undo.urls')),
(r'^openid/', include('apps.openid.urls')),
but if I move the openid entry to the top everything except the openid
works. Reguardless of the order when I call reverse they all work.

The bottom line is that Django only needs to be in your PYTHONPATH. By default Python already has its site-packages directory on the PYTHONPATH which is where this stems from. You can define the PYTHONPATH at anytime. Once it is there it is completely installed. You will want to get the django-admin.py file into your PATH so that you can easily access it with referencing it on the filesystem. It is useful to have Django installed in site-packages if you don't need to be switching between versions very often or it is a production server, for example. -- Brian Rosner http://oebfare.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Instantaneous response is > expected. Depending on the source data, there are a couple options, and there are also issues with latency: - use AJAX to queue up DE, submitting the form in the background while allowing the user to continue with a new form. This gives you the best UI, but is more complex - if you're on a LAN you have different latency issues than if you're on a GSM aircard, dialup, or a satellite connection - you can create a form with subforms that can gather large batches of data and them submit them all at once. This one's fairly easy, but comes with the risk that an unsubmitted form can cause more data-loss if the user accidentally browses elsewhere or closes the window.

If you're printing to a local printer (attached/accessible to the browsing machine), you pretty much always have to go through a print dialog.

Is it possible to integrate > these with a web app. Depends on how much data is coming off the barcode/magstripe scanner. Often the readers can be configured as a "keyboard wedge" which often means that the act as a virtual keyboard. For 1-d barcode scanners, this is pretty simple: read the barcode, send the data as keystrokes, and optionally send an or afterwards. Excellent for web. For mag-stripes such as credit-cards and loyalty cards, there are usually 2 tracks, of which usually only one is used for data. Much the same as a 1-d barcode reader, they send the data as keystrokes and optionally send a termination enter/tab character. This data being visible is usually not a problem. For 2-d barcodes and mag-stripes with 2 or 3 tracks of data (such as AMX credit-cards or US drivers'-licenses, most of which follow the 3-track AAMVA standard) on them, things get a little more complex. They send the data like keystrokes, including field and track/line delimiters and optionally a tab/enter afterwards. You'd have to have a text-box, click/tab into it, scan the card, get the data, and then parse the contents of that textbox (whether in JS or on the server-side). Scattering sub-fields of this data to the right places is...uh...an adventure :) You might look at Koha, OpenBiblio or Evergreen (three open-source library web OPAC systems, most of which at least deal with 1-d barcodes) for examples of how they treat barcode input. > Is anyone running apps like this? Yep :) > Can the above issues be dealt-with? Most of them, yes. > Can a browser provide the right kind of UI for these demanding but > unexciting applications? You don't give a lot of details on the characteristics of the data which may make a difference. Are there logical groupings in the data (in our instance, each phone is data-entered, each of which is usually on its own page, so there's a need to flip pages regularly, so they do a phone at a time, with 20-30 fields of data associated with each). Or, you can use AJAX something like Google Spreadsheets to dynamically add rows for DE use, submitting the row-content in the background. Django+Python+JavaScript can handle most of the requirements. Demand-printing on the web-client is the largest hurdle. And as a web-user, I'd want it that way, as I wouldn't want arbitrary websites to be able to send stuff to my printer unsolicited without giving me an option to cancel. Ho
Newbie trying to install django-trunk from svn on Ubuntu 7.10
Following http://www.djangoproject.com/documentation/install/ I'm stuck at the steps of setting up the symlinks to django. Step 3. ln -s `pwd`/django-trunk/django SITE-PACKAGES-DIR/django Step 4. ln -s `pwd`/django-trunk/django/bin/django-admin.py /usr/local/ bin One possible problem: not thinking very fast, I ended up checking out django-trunk into my home folder. Is that a mistake? Where shd it be? I tried several variations on Steps 3 and 4: sudo ln -s /django-trunk/django /usr/lib/python2.5/site-packages/ django sudo ln -s /django-trunk/django/bin/django-admin.py /usr/local/bin sudo ln -s django-trunk/django /usr/lib/python2.5/site-packages/django sudo ln -s django-trunk/django/bin/django-admin.py /usr/local/bin And also the same variations with passwords included inline instead using sudo. All of them resulted in broken links. Any clues? I did get django-trunk onto my PYTHONPATH, thanks to help from Brett Parker, so now when I type import django into the Python interpreter, I no longer get an error message. In other words, according to the instructions, django is actually installed, at least to some extent. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: newforms-admin replacement for core=True in inline models?
I wanted to bump this up, because if there is no solution I think this is an issue which needs to be rectified before it is merged to trunk. As Felix noted, without core=True support, anything listed as in-line *has to be created when you create the parent object. e.g. if a Pizza can have 1+ toppings, and the Topping name is a required field, and 3 Toppings fields are shown inline on Pizza creation, then *all three* have to be used, otherwise validation errors occur on Pizza. In the old django admin, this is not an issue with the Core fields, which identify what fields flag a field as "user is trying to be create me inline". (I apologise if this should be added as a bug to track etc instead of here. I am new to using a django branch, and I'm unsure on the policy on what I should be reporting. By looking in track, it seems that the current status of newforms-admin is very close to being merged with trunk (only a dozen or so minor issues listed as deal-breakers). However after a few days use, I have found various large issues, or at least undocumented backwards-incompatabilities. For example, this issue http://groups.google.com/group/django-users/browse_thread/thread/f889fce3e854257e# I posted in django users regarding one-to-one fields.)

You've two fields called docket in this model. That's not allowed.
Rename one of them and regenerate your model.
> name = models.CharField(maxlength=40)
> date = models.DateField()
> ...

Change those two lines like this (assuming docket is your ForeignKey
field to ParentFile):
{{ ChildFile.docket.city }}
{{ ChildFile.docket.country }}
Basically, you can get to a parent object by traversing the relevant
ForeignKey field of the child object instance. You might want to read
up on the DB API documentation for more details on this.
Also, it's a common convention to use titlecasing in class names and
not in instance names. So, in your template, I would suggest renaming
ChildFile to childfile or child_file.

Heads-down transaction-processing apps on Django
Sorry for posting such a nebulous question... Is anyone using Django web apps as heads-down transaction processing applications that are heavy in the areas of: - Lots of data entry - Lots of "instant, right now" demands like POS A few - slightly more specific - issues: - What about data entry into a web form. Data entry people use 'Enter' to move between fields, not Tab. And they won't touch a mouse. - Data entry people use lots of F-keys, Ctrl-keys and Alt-keys to make things happen on the screen. - Screens need to save and return *fast*. Instantaneous response is expected. - Printouts need precise on-paper placement and instant delivery (no pop-ups to select printer or preview). - Screens are dense with lots of tightly-packed fields. - There may be requirements to interface with barcode scanners and magstripe scanners (probably USB connected). Is it possible to integrate these with a web app. Is anyone running apps like this? Can the above issues be dealt-with? Can a browser provide the right kind of UI for these demanding but unexciting applications?

Re: FckEditor vs TinyMCE
It's certainly possible to implement FCK as a JS based editor, no python code necessary. It'll simply act as a textarea replacement to the user, but will still post the source of the editor when the form is submitted. Here's the integration guide for doing it this way: http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/Integration/JavaScript If you want to do it in your django code, here's the Python integration guide: http://docs.fckeditor.net/FCKeditor_2.x/Developers_Guide/Integration/Python Jay Cull wrote: > We're just starting to consider text editing. > What is our easiest path here?

It sounds like you are not using an absolute path. The way I handle a
CSS file across several pages is to have my base.html look similar to:
something
The first slash in /media/css/styles.css is critical since it tells the
webserver to look at the root of the domain. If left off it will become
relative to the page you are viewing. For example:
http://localhost/my_cool_url would then yield a lookup for
http://localhost/my_cool_url/media/css/styles.css as opposed to just
http://localhost/media/css/styles.css.
It is also common pratice to use MEDIA_URL to cut down on having to
always know the media path. Using it will change simple change the url
to {{ MEDIA_URL }}css/styles.css and MEDIA_URL = "/media/" in your
settings.py. Make sure you are using the RequestContext to ensure {{
MEDIA_URL }} is displayed correctly in your templates. (This will only
work if you are using HEAD of Django trunk, otherwise you must write
your own context_processor).

Ok, this seems to be a large misconception of what newforms-admin really is. Let's pretend the admin application doesn't exist for one second. You are left with newforms. You could go on your merry way writing forms that only authenticated users can access. Putting the admin application back in the mix isn't trying to stop you from doing that. It just provides you a thin layer of views, urls and many sensible defaults for an admin interface using newforms. The ModelAdmin class has two methods named form_add and form_change. This function returns a django.newforms.Form instance that will be used to render on the page. You could return anything from here. form_for_model should not be used and its ModelForm replacement is preferred. I am not 100% sure off the top of my head if there are any particular requirements the form must have, but if you notice anything wonky, please, open a ticket in Trac. > > Secondly, in the admin the potential to do multi-field validation is > gone (or seems to be).

This type of validation is very possible since the form clean_FIELD methods are never passed its own value. It is the job of the developer to pull out the values from cleaned_data that a clean_FIELD method, you are implementing, should care about. -- Brian Rosner http://oebfare.com --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

it. While following along in the django book, i did the steps
necessary to activate the admin page, including uncommenting the admin
url in urls.py. But when I go to http://127.0.0.1:8000/admin/, I get
the following error:
NameError at /admin/
name 'django' is not defined
Here is my urls.py file:
from django.conf.urls.defaults import *
from mysite.views import current_datetime
from mysite.views import hours_ahead
urlpatterns = patterns('',
(r'^time/$', current_datetime),
(r'^time/plus/(\d{1,2})/$', hours_ahead),
# Example:

I'm not entirely sure what you are asking, but I think the answer is: Yes. Are you asking about the flash script calling a URL, getting data back and then displaying it? If so, yes. Django doesn't know or care who is calling the URL, just as long as it's a well-formed request. We have several places where Django is serving data to an AJAX app, piece of cake.

PYTHONPATH is just an environmental variable, often if you're not already using it it'll be empty ;) You can check it's current value with: echo $PYTHONPATH If it's empty then you can just do: export PYTHONPATH=/path/to/django/trunk/checkout Otherwise: export PYTHONPATH=$PYTHONPATH:/path/to/django/trunk/checkout That should give you enough to be able to run the development server etc...

Slow/no response does not immediately equate to undoable. It more likely means that people who might have answered the question were doing something else (watching the debate, coding, sleeping, having a life). Regarding your question: Depending on the dynamics of your app, you might investigate the following: 1. If the profile is updated first and you want to propagate some changes to the associated User record, try overriding the save() method for UserProfile, do your thing, and then call super(UserProfile, self).save() to finish. 2.

Re: Complex relationship for user profile

It more likely means that people who might have answered the question were doing something else (watching the debate, coding, sleeping, having a life). Regarding your question: Depending on the dynamics of your app, you might investigate the following: 1. If the profile is updated first and you want to propagate some changes to the associated User record, try overriding the save() method for UserProfile, do your thing, and then call super(UserProfile, self).save() to finish. 2. If the opposite is true (User is changed and you want to propagate to UserProfile), avoid the temptation to hack contrib/auth/models.py. Instead, use signals.

Re: Have get_profile() delegate to one of several profile models depending on type of user
Thanks for the responses everyone. My final approach to this issue has gone more along the lines of Ivan's response, though with a twist. I now have a generic UserProfile model which is returned by the get_profile() method. All this model stores is the foreign key to the user and a 'user_type'. I have a method on this model that uses a modified form of Auth's own get_profile() method to retrieve the appropriate model based on the user type. Essentially UserProfile acts as a middleman between the User model and the appropriate Profile model for the situation. I agree with Ivan. I'm not fond of this approach either, but short of something like single table inheritance (which Django doesn't support), there's really no other (good) way to approach the problem. I guess the best approach would be to actually write my own authentication system customized to my app. I could get rid of the hackiness of my solution here, but that approach seems to have problems of its own.

Re: Complex relationship for user profile
Okay, Failing a response to that one must mean I'm asking for something that is undoable... could anyone provide an easy way to accomplish this by maybe extending the admin template or something? I'm convinced retrieving the data would be very simple, but is there a way to get it to save as well? Can you extend the form handler for an admin page?

Re: how to speed up objects saving
> I'll try to redefine save methods in all the objects to see how much time it > saves You may want to redefine the __init__ methods as well (it's called when you create your objects before save), it adds overhead of two more signals that are probably unused and can be removed for speed. You can try comment out all dispatcher.send() lines of __init__ and __save__ methods of Model class in /django/db/models/base.py and save the file as base2.py in the same place inside your Django package and say something like `from django.db.models.base2 import Model as MyModel' and replace model.Model with MyModel in class definitions. I know it's hackish, but it's easier and it works. :) Hope this helps, Ivan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

ForeignKey displaying related values
Hello all,
I am new to django, please excuse any naivity. I would like to list
child and related parent records from the scenario below. Although
quite happily displaying ChildFile records, I can't seem to display
any ParentFile records.
models.py
class ParentFile(models.Model):
recnum = models.AutoField(primary_key=True)
number = models.FloatField(max_digits=12, decimal_places=0)
date = models.DateField()
time = models.CharField(maxlength=5)
city = models.CharField(maxlength=40)
country = models.CharField(maxlength=40)
...
class ChildFile(models.Model):
docket = models.ForeignKey(ParentFile, related_name = 'number',
unique=True)
recnum = models.TextField(unique=True) # This field type is a
guess.
docket = models.FloatField(max_digits=12, decimal_places=0,
primary_key=True)
name = models.CharField(maxlength=40)
date = models.DateField()
...
views.py
def Outstanding(request):
fLatestRecs = ChildFile.objects.filter(name =
'DAN').select_related().order_by('-date')
return render_to_response('/report.html', {'fLatestRecs':
fLatestRecs })
report.html
...
{% if fLatestRecs %}
Date
Time
Name
City
Country
{% for ChildFile in fLatestRecs %}
{{ ChildFile.date }}
{{ ChildFile.time }}
{{ ChildFile.name }}
{{ ParentFile.city }}
{{ ParentFile.country }}
{% endfor %}
{% else %}
No Records available.
{% endif %}
Any help would be much appreciated.
Many thanks,
Eamon

Ruyan e-cigarette e-cigarettes v8 How to eliminate harm from second cigarette
As a former smoker, I know first hand how hard it is to quit smoking. My many efforts to stop failed until I was truly ready to quit. Whatever works is fair game in my book. The new e-cigarette, available mainly in China and Europe right now, may be just the answer for many who smoke not only for the nicotine but also the tactile pleasures of smoking itself. This new e-cigarette, made with a stainless steel shell, lithium ion battery, micro-electronic circuit, atomizing chamber, and indicator light at the tip delivers nicotine that is inhaled via a cartridge (that you refill as needed) that is inserted into the device. A vapor that mimics smoke is emitted (not much info on the vapor, presumably just water vapor) The "cigarette" even has a led light up on the tip to simulate the burning. At around 200.00 US dollars users will want to make sure they don't leave it in an ashtray (are there still ashtrays anymore?) The nicotine cartridges are sold in packages of 50 for around $90.00. While it isn't marketed in the United States yet, I see where a official company: RUYANHEALTH INTERNATIONAL LTD. (www.ruyanhealth.com) , is selling them online to US customers using pay-pay, etc here. They also sell eCigars. Who knows if this device will be anymore successful in helping people quit than the nicorette gum and patches but if helps cut down on people polluting our streets, houses, restaurants, and other public areas with toxic smoke I am all for it. Second-hand smoke is a killer. Nicotine is no sloucher either, last I heard Nicotine is a major contributer to coronary artery disease but if it helps the user actually quit it seems worth it. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

It's just a snapshot of the svn trunk at rev 7074... it should be fairly easy to install though, and it'd get dropped in to site-packages for all python versions installed. However, I've just glanced at the version of python-support in gutsy and it appears to be older than the version that package relies on...

The problem is not sending the encrypted string, but getting the decryption-key into the hands of the sales-rep so he can decrypt the encrypted string. And if you've solved that problem, you've solved the "how do I get a secret to the sales rep over the public internet?" problem. The aforementioned problems with one-time-pads is that *key* distribution and maint. becomes the problem. The only thing it does is allow you to defer transmission of an unknown secret. Useful Scenario: Alice and Bob are physically in the same room. Alice gives Bob a pad of OTPs and keeps a copy for herself. Bob goes to Supersekretistan where he uses the OTP to encrypt data and send it back to Alice, then destroys the generating OTP. Not So Useful Scenario: Alice is at home, Bob is in Supersekretistan. Alice uses $METHOD to securely send Bob a pad of OTPs, keeping a copy for herself. As above, Bob uses the OTP to send data back to Alice, destroying the OTP. In the NSUS, if you've solved $METHOD, then Bob can just use $METHOD to send the data back to Alice, and has no need for OTP[1]. $METHOD usually consists of something like public-key cryptography. -tim [1] The one caveat that occurs to me here is that it might be illegal in Supersekretistan to possess encryption software, but it might not be illegal to possess large volumes of random data and an XOR operator :) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Another option might be a long-running process (LRP) that listens
on a pipe for commands. In this case, the only command it would
accept is "adduser", and it would create a user based on the
syntax of the command sent. Thus, your LRP might listen on
/tmp/adduser-pipe so your unpriv'ed web-process would connect to
this pipe and write something like
aup = file('/tmp/adduserpipe', 'w')
aup.write("joe Joe Smith\n")
aup.close()
Your LRP would then read this command and create a user named
"Joe Smith" with a login of "joe". One might get more elaborate
for error-handling, but this would place clear lines of
permission division between the dangerous user-adding code and
the hairy world of teh intarweb.

The way in which you handle the application-level transactions that span across a set of requests it entirely up to you :-) Thinking of typical scenarios you could either synchronize data in real time (something like google docs), synchronize on save (some kind of diff and merge), warn users before they start editing a record which is already opened for edit by another user (like in MoinMoin) or just overwrite or ignore changes (like in all bad-user-experience-apps). The third option seems quite reasonable and its also not very hard to implement. All what you will need is a (generic) registry that will hold information about checked out objects (rows, records, documents - whatever the naming convention is) and some locking logic. The registry could be simply a model with three fields: [generic] model foreign key, user foreign key, and a checkout time, with unique constraint on the model foreign key. If you don't need to track different models then a "classic" foreign key instead of a generic contenttypes one should be just fine. The functions that will provide a locking interface should be atomic (that's the place where the database level transactions come into play). A typical pattern is to have at least an acquire (lock) and a release (unlock) routines, plus a couple of additional helpers for the typical use cases: * acquire_lock(object, user) - creates an entry/replaces expired one in the registry, allows for re-entrant locking (the same lock can be obtained many times by the user that already possess it without raising an error), raises an exception if an object is already locked by another user and the lock period hasn't expired. * release_lock(object, user) - removes lock from the registry * is_locked(object, user) - checks if a valid object lock entry exists Cyclic removal of expired entries from the registry should not be necessary unless you count for every byte or need to reduce number of queries (in a typical case they will consume considerably less space than the other models' data). After setting this up you should have a pretty robust mechanism for controlling parallel access attempts to database records/objects. Just lock the object on edit, release the lock on save and issue a warning on concurrent edit attempts. > I've seen some table layouts that included a column like "last_edit_serial" so > that a steadily incrementing serial could provide a hint to the app level that > something had changed since the record was loaded.

The 0.96 package there is just the one from Debian, the only changes that are made to the debian package is that django-admin.py becomes django-admin as it's installed in to /usr/bin (django-admin.py is still in /usr/lib/python-django/bin, along with the other django scripts). (Except the version in hardy, which rewrites the shebang of manage.py when manage.py is created - which we used to have in the debian packages, but removed as using the system default python is the correct behaviour as a default, and if you're not using the default then you already know enough to run manage.py in the interpreter of your choice). There are svn snapshot packages available from the debian experimental repository, with some pinning you should be able to pull in that and only that from the experimental repository.

Re: how to speed up objects saving
You have two options: 1. Execute raw SQL 'INSERT' queries 2. Override the Model.save() or create new save_fast() method in your Model class. The main speed eaters in Model.save() are dispatcher.send() calls - so if you copy/paste the content of save method from Django code without dispatcher.send() lines you'll get a reasonable speed increase. --Ivan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: form for display, not edit
I also have something similar: I created a bunch of display widgets (displaytextinput, displaytextarea, displayselect, displayselectmultiple etc.), which override the render method of their parents and created a subclass of forms.ModelForm for this, which has a display_only argument on the __init__. If that argument is made True, I replace the widgets on the fields with my custom ones. Pretty ugly, but works ok for now. In my case, I wanted all elements display_only or editable, but off course you could fine-tune this. Notice I am not using the form_for_model stuff anymore, since it will be deprecated soon.

Re: Persistent data (other than sessions)

If this thing doesn't change, then you could build it once and then
stick it in a module-level variable. Something like:
final_graph = None
def graph_search(request):
if not final_graph:
final_graph = build_graph()
result = search_graph(final_graph, some_parameters_from_request)
return render_to_response('template.html',{'result': result})
Note that this is a *very* naive implementation - you'll need some
locking around final_graph access to prevent race conditions. You
might want to consider using a thread-local storage. You'll also need
to unset this module-level variable (again with locking) if your
underlying graph data changes.
Cheers,
Dan

how to speed up objects saving
Hello, I have a problem: on my website I periodically need to transfer some data from a DB, to the Django DB of the website (I currently use MySQL) what i do in my view is to call some SQL queries on the "from" database, make some calculations and rearrangements on the data to transfer, then call several times the .save() method to store the data in the (django) destination database. this procedure takes a long time (about 40 minutes) on the server is there a way to speed up the insert process? I mean, in MySQL it is common practice to use long INSERT instructions to speed up the process, is there a way to do something similar in Django, rather than calling .save() thousands of times?

I've been using the following for something similar:
class PlainText(forms.HiddenInput):
def render(self, name, value, attrs=None):
return u'%s%s' % (forms.HiddenInput.render(self, name, value,
attrs), value)
def myobject_formfield_callback(field, **kwargs):
if field.name in ('hostname', 'ipaddress'):
kwargs['widget'] = PlainText()
return field.formfield(**kwargs)
else:
return field.formfield(**kwargs)
def myview(request):
myobject = get_object_from_somewhere()
initial = myobject.__dict__
FormClass = forms.form_for_instance(myobject,
formfield_callback=myobject_formfield_callback)
form = FormClass(initial=initial)
...
In my example I just want certain fields to show as text. If you want
that for all of them change the formfield_callback to always change the
widget.
If you only want the plain value without a hidden field change the
PlainText.render method accordingly.
Works for me.

Re: url tag and reverse()
> Have you tried this:

Strange, I had thought that wasn't working, but I guess it must be. So
with that change this gets the right URL:
reverse('entry',
kwargs={'translatorName':'johndoe','entryName':'blogentry'})
But trying to use the entry view, which requires two arguments, simply
gets a "Could not parse remainder of argument" for whatever comes
after the first word, whether I use positional or named arguments.
And still, neither of these produces anything:
{% url translator translatorName=johndoe %}
{% url translator johndoe %}
URL is meant to be able to take multiple arguments, isn't it?
Thanks for your help...

There is no built-in automatic solution for this. However, like many things which are not built-in or automatic, it is quite easy to write a view which accepts a user's file upload and places it wherever you like. -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
