m2m admin relationship selector with filter_horizontal and large datasets
I have a Category model that is m2m with an Article model and need to make categories selectable in my article admin. So I'm using a filter_horizontal and the problem is that I have thousands of categories and do not want to load them all into the left hand side (lhs) of filter_horizontal. Is there a way to limit the lhs to just a search functionality instead of a category browse? Is there another widget I should use just for searching categories to make m2m relationships?

Re: Beginner: What are the pitfalls of using an html form without using django forms? I.e. form.py
Hi Tdkwon,
What the benefits using django forms something like :
1. You can reuse it on another view programmatic way, not copy paste html only
2. You have the definition of form in 1 place rather distributed on many views
to change it.
3. You have the helptext, error message, validation, css class
4.little code in views to process form data and save to models
Try it and tou will found it more usefull

Mulianto

Is that possible to define a manager only for this purpose? Is > it a good practice? > Only if you can perform that calculation "database-side". Since you want to do a filtering operation, the property you want to filter on must either be stored on the database, or computable via the database. Essentially, the manager needs to be no more than a shorthand for a query chain using normal Django query clauses. You can't use a method on the *model* because that value will only exist on the Python side of the query, not the database side. (A quick caveat - you *could* do it by filtering on the Python side - essentially, you filter as much as possible on the database, and then provide a Python-side filter - essentially "[s for s in Service.objects.all() if s.distance(some_user) < maximum_value]" - but that puts additional load on your web server. If your list of services is short to start with, or can be filtered to be relatively short, this might be a viable option - YMMV) In some cases, the database filtering can be helped by pre-computing a filterable value and storing it as a value on the database model, so you can use a simple Django filter on that value. However, in your case, it's not just about the lat/long of the object being filtered, but the lat/long of the user as well. Managers themselves can't take arguments, so the closest you'll get is a method *on* the manager that can return a queryset. The fact that the method is on the Manager is largely irrelevant - that's just a convenience. You need to be able to construct a query chain, using purely database-side queries. Putting that method on the manager is really just a convenience to put the query in an obvious place; being on the manager doesn't give the query any additional power. If you're using Django 1.7, you should also look into using custom query sets *as* managers: https://docs.djangoproject.com/en/1.7/releases/1.7/#calling-custom-queryset-methods-from-the-manager This means you'll be able to access your "nearest filter" anywhere in a query chain. After all - does it really matter if you say: Services.objects.nearest(some_user).filter(is_fun=True) or Services.objects.filter(is_fun=True).nearest(some_user) (Maybe it does in your particular case, but broadly speaking, it shouldn't). You may also want to take a look at django.contrib.gis (also known as GeoDjango): https://docs.djangoproject.com/en/1.7/ref/contrib/gis/ This toolbox gives you a whole bunch of useful tools for performing geographic queries, including computing the distance to a point, determining if a point is inside a polygonal geographic boundary, and so on. It's a little more difficult to set up, but it's much more powerful (and accurate) than a simple lat/lng pair. The Expressions API that will be part of Django 1.8 would also be useful to you: https://docs.djangoproject.com/en/dev/ref/models/expressions/ However, that would be riding the bleeding edge of Django, so unless you're looking to be particularly adventurous, I'd stick to the more stable options. > 2) The computed value is not just useful for the QuerySet, but I need > also that on client side so I serialize it and I send it using JSON. > Is possible to make sure that the manager attach the field "distance" > to the objects in the QuerySet? > If it's available for the database to filter, then it will automatically be on the objects in the QuerySet, which means it will be available for serialisation.

Modify a queryset and add computed value to the objects
Hi everyone! I have a "Services" model and I would like to get a QuerySet with all the services filtered based on the distance between the logged user and the service. I have latitude and longitude about the user logged in and I filter the services based on the computed distance. At the moment I build the QuerySet Service.objects.all() and after that I exclude the services that I don't need, but I think there is a better way to do that. I was thinking to use a Manager. Quoting the docs: "Adding extra Manager methods is the preferred way to add “table-level” functionality to your models. (For “row-level” functionality – i.e., functions that act on a single instance of a model object – use Model methods, not custom Manager methods.)" As a "eternal newbie" I ask you 1) The distance must be computed based on two parameters "long" and "lat". Is that possible to define a manager only for this purpose? Is it a good practice? 2) The computed value is not just useful for the QuerySet, but I need also that on client side so I serialize it and I send it using JSON. Is possible to make sure that the manager attach the field "distance" to the objects in the QuerySet? Thank you! -- Karim N.

Re: Changes to Model does not migrate to sqlite with Django 1.7?
Hi, I'm afraid I don't have them. Apparently after deleting my database file and then just running manage.py makemigrations, it deleted the old migration files and started anew. Right now I'm also unable to re-produce it on purpose :( But it happened a couple of times for me since I regularly make multiple changes to my model (I'm still at the beginning of development) but if I just add a single new field now it works as expected. Maybe sometimes Django can't detect changes to my file because I store my project in my dropbox folder and maybe this might be messing it up?

Re: Connect django project with sharepoint 2013
Hi,
You may have better luck using the ip address directly instead of "portal".

Re: Open a url with user and password
Hi,
My first guess is that it's using NTLM authentication instead of basic
auth. If you curl -i http://portal:8080/ what "authenticate" headers do you
get?
Also, you should consider upgrading to python 2.7 if you haven't :)

Re: How to set choice limit of given number on ModelMultipleChoiceField in Django?
Hi,
On the html form, you could probably use javascript to filter out the value
in the many to many when you select the primary language.
In the django form, you could add extra validation by defining
form.clean_further_languages(self)

You can provide your custom set of default errors to the form field
definition, e.g.:
my_default_errors = {
'required': 'You better enter this field!',
'invalid': 'You can do better than that!'
}
class MyForm(forms.Form):
some_field = forms.CharField(error_messages=my_default_errors)

Re: Bug in staticfiles' HashedFileMixin?
Hi Bernhard,
Yes, on quick glance this looks like a bug. It looks like all replacements
get applied to all matching files. Feel free to open a ticket if you
haven't. (If you have, feel free to link to it in case someone else finds
this.)

Re: Error: 'NoneType' object has no attribute 'strip'
Hi,
Looking at your traceback, it doesn't look like it's calling your custom
save() method. Do your current tracebacks show your custom save method?
You could try print(vars(self)) right before saving to see if there is a
None that shouldn't be there.
Again, if the traceback is happening in the browser, see if you can figure
out what's in the "params" dict by clicking "local vars".

Hi,
If you remove all the slug code do you still get this error? If so,
then the error has nothing to do with automatically creating a slug.
Try expanding Local vars to see what "params" and "sql are.
File "e:\python\lib\site-packages\django\db\models\sql\compiler.py" in
execute_sql
920. cursor.execute(sql, params)
File "e:\python\lib\site-packages\django\db\backends\utils.py" in
execute
85. sql = self.db.ops.last_executed_query(self.cursor,
sql, params)
This does seem like a bug in mysql-connector. You may want to bring it
up on the mysql-connector list. http://forums.mysql.com/list.php?50
You could also try using mysqlclient instead to see if you still have
the problem. That's django's recommended connector.

Re: Backup vs Audit
I've used dbbackup with success - a cronjob to copy out the database (and replace the testing and staging databases with "yesterday's data") and copy it to another machine. Regards the Django admin interface, there are a number of points to consider: - the base interface will always be in the Django source repository, and is well tagged. You should always be able to redeploy from that - any adjustments you have made could be going into another source repository (git, mercurial, svn) of your own - which is another backup again. If you aren't putting your own changes into a source repository, I would suggest that is an excellent start. FWIW, and I apologise for sounding like a broken record, Danny G and Audrey R's Two Scoops of Django is an *excellent* place to start if you are comfortable with the tutorial and looking for a "what next" text. I found it invaluable for helping with these weird little decisions that seem so far from the actual creation of the site you are making. L.

This sort of behaviour is not built in to django - there are good packages that provide it, but why go to the complexity given the points in 1). There are plenty of audit trail packages that integrate with django admin, since audit trails are simply model instances tracking changes to other model instances. Keywords "django audit".

Re: Backup vs Audit
Most of the tools I've found is administered from commands and no template Django admin. What I want is to do both operations from the manager but found nothing. Help!! For example, proven tools are auditlog and dbbackup.

There's nothing wrong with doing that, of course. Just as you can write raw
SQL to talk to your database, and even raw WSGI to power your web app. But
Django provides utilities like the ORM, and the forms framework, to make it
easier for you. If you find they don't help for your use case, then feel
free not to use them.

Make sure the last line is indented to the same level as the others.
