Re: Django 2.2 and custom media in the admin

[Thorsten Sanders]

Hello,

thanks did overread that twice then, once when reading changes, once 
when trying to figure out if there was a change due not working.

Then i searched for it and came to:

https://docs.djangoproject.com/en/2.2/ref/contrib/admin/#jquery

Maybe not bad idea to mention it there too.

Hello Thorsten, this is a change document in the 2.2 release notes[0].

There's even a resolution example for a django.jQuery dependency like

Hello,

I insert a custom javascript inside the admin and do use the

With 2.2 the order in which the javascripts are loaded changed and
the jquery.init.js is now loaded after my custom javascript, is
that considered a bug or a change?

hashed password using *ReadOnlyPasswordHashField()* I get an error 
inside the password field, even though I used *set_password()* for the 
Manger inside the *create_user()* function.


/Invalid password format or unknown hashing algorithm/


However, if I manually do *set_password('strongpassword')* for that 
user inside the console, then only the password is hashed. Could you 
please help me solve this problem. Thank you.

Re: Logout user on tab closing

[Thorsten Sanders]

I wouldnt do that at all, lets take ebay as an example when I use that I 
have several tabs at the same time open and it would be really annoying 
if I get a logout if I close one of those tabs and the same is true for 
many other sites.


Same is true for my bank too, they just do a logout if I dont do any 
action for 12m thats the better way if security matters and if on tab 
close, there should be maybe some sort of popup asking if you want to 
logout.

the browser doesn't notify the server when the tab (or window) is closed.

remember that the original web architecture was simply about
downloading HTML documents and showing to the user.  Once the download
has happened, we're done with the server.

the whole concept of "web application" is javascript running in the
context of a web page, so you need the application itself (not the
browser) to notify the server.  You can use the "on-unload" event; for
example with jQuery's .unload() event hook.  Note that this event
fires every time the page is unloaded, not only when the window or tab
is closed, but also if the user navigates to another page (either via
the URL bar or by clicking any link), uses the 'back' or 'forward'
buttons, or even when reloading.

that's why most web applications rely on timeout and not on trying to
detect the user leaving the application.

The version of python can make quite a big difference, years ago with

Thanks, I tried that, it makes the query right, but when I access the

not sure if it's related. but most SQL adaptors use a tuple for the
IN(...) parameters, not a list.

check http://initd.org/psycopg/docs/usage.html#tuples-adaptation


I suspect the main problem is that you need to set up the realms
parameter differently -- along with the query string.

MySQL, and most other SQL systems, as I recall, expect to see

... needle in (first, second, ..., last)

MySQLdb sanitizes parameters by converting them to a string
representation, escaping any special characters, and wrapping it is '
marks.

In the raw query, unless Django has an SQL parser, the above is
generating

select * from auctiondata_auctiondata where itemid_id = 'something' and
realm_id in '[1]'

when what you need to generate is

select * from auctiondata_auctiondata where itemid_id = 'something' and
realm_id in ('1')

(MySQLdb doesn't know what datatype to put in at each %s -- it has first
converted all inputs into safe strings; that's why it uses %s for the
placeholder).

If using a list of values, you'll have to create an SQL format with a
%s for EACH value, not the list

SQL = " ...%%s and stuff in (%s)" % ", ".join("%s" for x in realms)
(if realms is [1, 3, 99] this creates   
SQL ="... %s stuff in (%s, %s, %s")

You then need to flatten the parameters

parms=[itemid].extend(realms)

Problem with raw query and using in

[Thorsten Sanders]

Hello,

wondering if I am doing something wrong or it is a bug, using django 
1.5.5, but also tried with 1.6 resulting in the same problem.


When I do the following:

realms=[1]
data = AuctionData.objects.filter(itemid__exact=itemid,realm__in=realms)
data2 = AuctionData.objects.raw('SELECT * FROM auctiondata_auctiondata 
WHERE itemid_id=%s AND realm_id in %s ',[itemid,realms])


The first query works as expected, but the 2nd one fails, because the 
query ends up as:


SELECT * FROM auctiondata_auctiondata WHERE itemid_id='43552' AND 
realm_id in ('1',)


The last comma shouldnt be there, if I use more than 1 value with the 
realms variable it works and the last comma isn't there.

Thorsten

Re: Associating Form Data with Users

You could do for example:

exclude the user field from the form and in your view something like this:

form = YourModelForm(request.POST)  #fill the modelform with the data
if form.is_valid(): # check if valid
mynewobject = form.save(commit=False) #save it to create 
the object but dont send to database

mynewobject.user = request.user # attach the user to it
mynewobject.save() # now do the real save and send it to 
the database

the idea that after authenticating the user in the view, request.user
be set to some variable that allows the user ID to be added to the

How about you give it a try and see what you can figure out? In your
view, request.user will return the currently logged-in user (or an
AnonymousUser if they're not logged in). Since you said your view
requires login, you'll have a User object all ready to go.

template code is available in django-mode


* Semantic knowledge of Django projects
  - jumping between a view and its template


This can also be done with django-mode


* Much better debugging story
  - Pretty good visual debugger with watches and conditional
breakpoints
  - Remote debugger (via a specific agent)


Therefore I use pddb outside of Emacs

  - Django templates debugging

Yep that's also something I miss. Can partly be done with Werkzeug
in the browser

For me Emacs has the far better editing features than the Eclipse
editor with stuff like rectangle edit,
macros and the like and it's very good extensible and therefore
can perfectly adapted to one's needs.

With some trying arround, I came up with the following:

from django.db import models

  else:

Inside model then for example:

name = TransCharField(max_length=255)

I did some testing and it seems to work proper as I want it, I can just
use the orm normal and using name and inside the query the field get
translated to the right name.

My question is if that solution can have any side effects or if there is
a better way to do that, I will btw only do read operations on those
tables, there will never be write/updates to it via django.

syncdb etc woud break for sure, but it seems that will not be a
problem for you. Serialization will give you only one language. I
can't think of anything else that will break for sure. On the other
hand, it wouldn't be surprising if the list of things that do not work
would be a lot longer. If it works, use it. But it will not work 100%.
Yep I know syncdb breaks and that is not a big problem for me, 
serialization if used should only give 1 language as well and prolly it 
will be used and exactly the "it wouldn't be surprising if the list of 
things that do not work would be a lot longer" is why I am asking, I had 
it before that something works nice 99% of the time but the other 1% it 
dont, in a upcoming project I plan to use that approach for a lot of 
queries and would be quite bad if some side effects will appear, because 
it would be prolly a lot of work to change it.


A safer way would be to do something like:
SomeModel.objects.filter(t('some_column')=someval).order_by(t('some_column'))

def t(col):
 return '%s_%s', (col, get_language())

Re: Django Tutorial Part 3 Decoupling the URLconfs

[Thorsten Sanders]

You are using the tutorial of the development version which is 1.4

django.conf.urls.defaults instead of django.conf.urls

Better use the 1.3 tutorial instead of the development one to not run into such

Can you tell me what is going wrong here.

 Just an aside: seems like a convoluted plan to keep round-tripping
to the server/database each time you refine the filter.

 I'm presuming the initial data set being sent is the "full" list. If
so, might it not be useful to somehow (Caveat: I'm /not/ skilled at
this, only toyed with Javascript too many years ago) embed a Javascript
action to count the categories, render the filter selections and, when
one is picked, have the Javascript modify the page in-place to display
only the filtered data?

 Granted, adding another language on top of Python, Django, and the
template language, may be more than desirable.

Caching and excluding in a template

[Thorsten Sanders]

Hello,

wondering if there is any easy way to exclude a little part from a 
template to be cached, on every site there is a the usual register/login 
or you are logged in with a user menu, back in php+smarty times it was 
easy solved using a dynamic tag to easily exclude a small part from 
being cached.


So far I only saw you could turn off caching for logged-in users or fine 
grade what is being cached, the first I dont want (only caching stuff 
which looks same for all users except the user menu) and the latter 
seems to be quite some work compared to just exclude a litte part in the 
base template.


Greetings,
Thorsten

Of course I would like to create a django model for the table, because

I have already done this previously, however in this case the table
has a multiple field primary key, unsupported by Django. There is no
other field which is guaranteed to be unique that I can use as primary
key in the Django model.

Do I need to worry about this? or can I just slap the primary_key flag
on any of the fields, since I will never be inserting or updating in
that table?

Re: Django orm and no primary key

[Thorsten Sanders]

Am 10.01.2012 20:46, schrieb Ian Clelland:


This is possible -- there was some discussion on this list about it 
just a few days ago. If you tell Django that another field is the 
actual primary key, then it will not assume that there is an 'id' 
column (which is good, because otherwise it will try to include that 
in any SELECT statements that it issues).
Seems I should read more often the list, then I wouldnt have missed that 
one.




As long as you consider this table to be essentially read-only, and 
you don't try to use the ORM to create any records in it, then you 
shouldn't have any problems with this. As specific measures:


- Don't try to create records with Model.objects.create() or 
Model.objects.get_or_create()
- If you have to retrieve records, use filter() rather than get, if 
you can't ever assume uniqueness
- Similarly, if you have to update records, use update() rather than 
save().


It sounds like you want to use aggregate queries on this table anyway, 
so you (hopefully) shouldn't run into any issues.
Yep that fits from the orm side it is only reading to aggregate 
statistics from a table holding history data, I like the orm style way 
easier to write/manage than raw queries hence my question, the 
inserts/deletes are handled lowlevel without django.


And cheers for the answer gave me the motivation to try it out in the 
near future, currently I only still got that "primary key" to not break 
the orm, removing it would free up quite some not needed space if it works.


Oh, and don't register this model with the admin; most of that 
framework is built around the idea of rows uniquely addressable by 
their primary key.

Django orm and no primary key

[Thorsten Sanders]

Hello,

I am wondering if it is possible to still use the django orm without 
having a primary key at all, I currently got a table holding 61 million 
entries soon gonna expand to hold 600 million entries, that table never 
need to identify one entry alone its only to pull off statistics based 
on other fields, so far I  dropped the primary key index in the database 
and all works fine, but I know the orm always want a primary key, would 
it still work if I for example claim one of the fields which aren't 
unique as the primary key?


Or is the only way to do it, use the cursor or even mysqldb directly?

Greetings,
Thorsten

Re: This Week In History

[Thorsten Sanders]

You dont mention the database you use if mysql you could do

SELECT * FROM  WHERE DATE_FORMAT(, "%u") = 
DATE_FORMAT(curdate(), "%u")


dont know if there is a django orm way to do it, but could always use a 
raw query.

Hi Folks,

Does anyone have a strategy for selecting from a database where the 
date is this week, but a random year in the past?


I have ~100 years of events in a database, each with a datefield - I 
would like to do a "this week in history" box that lists one or two on 
the homepage, randomly taken from the set.


Ideas/pointers appreciated.

Cheers,

Tim.

Re: Checkboxes for a list of items like in Django admin interface

[Thorsten Sanders]

I missunderstood due "and in a view loop through somename list" thought 
you mean you delete them 1 by 1 :P


And the orm itself tries to convert the value to an int and throws an 
ValueError if it fails, so find it a bit double to check myself and let 
the orm do it again.

You can't forgot to sanitize the input in this case:

id_list = request.GET.getlist('id_notification_list')
id_list = [int(i) for i in id_list if i.isdigit()]
notifications = Notification.objects.filter(
id__in=id_list,
)

Re: error attempting to populate field

[Thorsten Sanders]

Because its a foreign field either get an instance of Listings with that

listening = Listings.objects.get(id=15)

CanoeKayak.listings = listening

or to add directly a value:

CanoeKayak.listings_id = 15

Tim Shaffer's response would have you doing N+1 queries, and

Technically it would work, but as soon as you have a decently

Indeed and I have to sort and pick a subset of the sort after that. I 
can't run a loop through thousands and thousands of items to only 
select a hundred.


The best way I can see to do this straight with the Django ORM is:

prop_dates =

Target.objects.annotate(latest_property=Max('property__export_date')).values_list('latest_property',
flat=True)
properties = Property.objects.filter(export_date__in=prop_dates)


Let say I have two targets which I'll call target1 and target2.

Target1 have a property for yesterday and one for today. Target2 only 
have a property for yesterday. Both yesterday and today will be 
included in prop_dates since they are the latest for at least one 
target. And then Target1 will have two entries in properties while it 
should only have one for today.



Which comes out to two queries. If you absolutely had to, you
could execute some raw SQL to narrow it down to one query. Please
note that there is a (very) small possibility that the second
query might return extra Properties for a given Target. Because
it's operating based on date-timestamps, there could be two
Properties that happen to have the exact same export_date, one of
which happens to be the most recent for a given Target.
Eliminating those duplicates, if you want to account for that
scenario, can be done in-memory or I believe through some
adjustments to the second line above.


I just designed a SQL query, I am wondering if I couldn't translate 
the logic to the ORM. It looks like this:


select * from Target_Mgmt_target as t
inner join (select *,max(export_date) as max_export_date from 
Target_Mgmt_property group by target_id) as p on p.target_id = t.id 
 and p.export_date = p.max_export_date;

--

from django.db.models import Max
Target_Mgmt_target.objects.annotate(export_date=Max('Target_Mgmt_property__export_date')).values(you want>)


This should work

Re: Delegating a async job from a django view

Take a look at that, it should be able to do what you want, though never
