during the thread so I thought I'd mention it.

AFAICT the problem is really not a problem at all. It is data integrity 
protection which I should not be trying to circumvent. The save, plus 
any pre-save and post-save activity takes place in a single transaction 
involving the main record and all children. Only when that transaction 
is committed and succeeds is the database actually updated. That says 
the children and master are updated more or less simultaneously.


I think it has to be done in two transactions. Two saves.

Hence, I need to find a way of updating the children in a first 
transaction which is committed and updates the database before the 
master can find the new proportion values when it goes looking during 
the next save (or second transaction).


If I wasn't using the admin, I could do that in my own forms without too 
much trouble.


Or javascript might look at the in-browser children values and change 
the sum in the master record in the browser. At that point a save puts 
the precalculated sum into the database at the same time as the changed 
values in the children records.


I looked at javascript once and nearly vomited. We'll save() twice until 
we get some funding then I'll hire a js person to let me off the hook ;-)


Thanks again

Aaaargh!!!

I forgot to tell you that the ingredients are inlines and proportions get
saved when the mixture is saved.

If there is a way to save inlines *before* saving the main record the problem
might be solved.

Otherwise the only solution I can see is to inject some javascript into the
Admin to read the proportion values and update the sum field just prior to
saving the lot.

At this point I think a double save is easier than js

Logically, this is a tail-chasing exercise. The total sum of ingredient 
proportions is calculated from a query of ingredients. It runs when 
saving the mixture. It can only get previously saved data.

Re: Check if all boolean values are the same (database)

[Shawn Milochik]

I'd go with form validation -- you shouldn't allow a Purchase to be added
to a transaction if a Purchase with a conflicting status is already in
there, nor should a Purchase be able to be modified if it's in a
transaction with another Purchase.

Then you never have to check whether a transaction is valid. The models
pasted don't give the complete picture of the relationship, but garbage in,
garbage out, so just don't allow them to exist in the first place.

Check if all boolean values are the same (database)

[Victor Porton]

# May contain several purchases
class Transaction(models.Model):
name = models.CharField(null=True)

class Purchase(models.Model):
bundle = models.ForeignKey(Transaction, null=True)
recurring = models.BooleanField(default=False)

For a given transaction, all its purchases must either all be recurring
 or all non-recurring.

What is the best way to check it (and throw an exception if in a
transaction there are both non-recurring and recurring purchases)?

Is it possible to Atomically check limit and Increment/decrement a counter field in multiple tables ?

[sarvi]

I have 2 tables Cluster and Node, each having a volume_limit and 
volume_count column in it.
To atomically check and increment the volume count for a Cluster and Node I 
do the following
updated = Cluster.objects.filter(id=cluster_id, 
volume_count__lt==F('volume_limit')).update(volume_count = 
F('volume_count')+1)
if not updated:
raise Validation('limit reached ..')
updated = Node.objects.filter(id=node_id, 
volume_count__lt==F('volume_limit')).update(volume_count = 
F('volume_count')+1)
if not updated:
Cluster.objects.filter(id=cluser_id).update(volume_count = 
F('volume_count')-1)
raise Validation('limit reached ..')


I am wondering if there is way to do both of this atomically?

Basically I want to 
   1. create a query for Cluster, Node, etc, N such objects/tables queries, 
that each filter match one row by pk and volume_count__lt=F('volume_count')
   2. Check that the union of all these queries translates to exactly N 
objects, one for each Object/Table. i.e. the counts are within limit for 
each object/table
   3. Do a volume_count=F('volume_count')+1 for all those objects/table 
together.

How do I do this?

Thanks,
Sarvi

Using postgres ts_rank's normalization parameter in django?

[Thomas Nyberg]

Hello,

I've been looking at the documentation on this page:

https://docs.djangoproject.com/en/1.10/ref/contrib/postgres/search/

I am trying to use the postgres ts_rank function as exposed through 
django. The ts_rank function in postgres can be called in (at least) two 
ways:


* ts_rank(tsvector, tsquery)
* ts_rank(tsvector, tsquery, normalization)

The normalization integer is documented here (textsearch for normalization):

https://www.postgresql.org/docs/current/static/textsearch-controls.html

I don't see in the documentation where this is exposed in the django 
side of things. How do I make use of that option?


Thanks for any help and sorry if I'm just blindly missing something 
obvious in the documentation.


Cheers,
Thomas

Re: Inconsistent types in PostgreSQL RangeFields

[Tim Graham]

The documentation says, "All of the range fields translate to psycopg2 
Range objects  in 
python, but also accept tuples as input if no bounds information is 
necessary."

It looks to me like you could initialize the objects using psycopg's Range 
objects to eliminate the need to handle the tuple case. The tests have some 
examples: 
https://github.com/django/django/blob/master/tests/postgres_tests/test_ranges.py

Re: Saving Data in Multiple Selected Checkbox for Voting System

[ludovic coues]

You provided vote from views.py but vote redirect the user. It does
not use the provided voting.html template.

Also, in my opinion, they are way too many if and for. You have three,
nested, loops. And you are using only a subset of each loop data.
I assume position.organization is a foreign key. So you should be able
to do "{% for position in organization.position_set %}" instead of "{%
if all_position %}{% for position in all_position %}{% if organization
== position.organization %}"
Just the same, you should have a position.candidate_set, with the list
of all candidate in a position.

I hope that help.
These information come from the models.ForeignKey documentation [1]
which point to the queries documentation [2]

Re: How to login different user each on different pages using class based views

[ludovic coues]

I would add a get_redirect_url method on all user model, which give a
different url depending on the user category.
Then use a redirect url with a get_redirect_url method returning the
value of get_redirect_url from the user.

If you want to use url name instead of path, use django.urls.reverse

Inconsistent types in PostgreSQL RangeFields

[francois-xavier . thomas]

Hello all,

I've been hitting a small annoyance when using the RangeField classes in 
the PostgreSQL contrib modules : while the value returned by psycopg is a 
psycopg.extras.Range type, the Django documentation explicitly mentions 
using tuples when creating and updating model instances.

This means that any method or property that has to process RangeFields must 
handle both tuples and Range types, which are incompatible.

For example, here is a very simple model :

class MyModel(models.Model):

range = DateTimeRangeField()

def has_started_1(self):
return self.range.lower() <= timezone.now()

def has_started_2(self):
return self.range[0] <= timezone.now()

In this naïve implementation, the `has_started_1` method will crash when 
used like this :

instance = MyModel.objects.create(range=(timezone.now(), timezone.now() 
+ timezone.timedelta(days=5))
instance.has_started_1()  # Crash
instance.has_started_2()  # True

...and the `has_started_2` method will crash with this :

instance = MyModel.objects.last()
instance.has_started_1()  # True
instance.has_started_2()  # Crash

How should I handle that better?

Thanks for your help!

Re: Django Admin keeps redirecting to login page repeatedly

Yes, I removed that middleware and its working fine now. I would always
keep an eye these third party tools before blaming to django core.
Thanks for the advice.

 Hi Everyone,

 Since last two nights, I am struggling a lot to resolve the issue as my

 I had tried every corner solution to resolve the issue, but failed to
 resolve it.

 Finally I am writing here in some hope that someone who already had the
 similar issue would help me to resolve it.

 So I am using Django 1.9.4 and when I logged into admin section then
 its seems to be fine but when I reload the page or click on some button
 then it redirect me to login page, As per my investigation I found that I
 am getting 302 for *"admin/jsi18n"* see the below screenshot..


 

 Below is the screenshot after reloading the above mentioned page..


 



 I would really appreciate the help to resolve the issue and I need to
 move for production asap.

No idea but it seems like you should update your requirements per that

Zappa , which includes all of the 
django-zappa features and more!"

Even the latest version of django-zappa doesn't have a middleware anymore.
