Re: Can we use python related api's on the Django templates ?

[Derek]

While you cannot use Python operators and functions directly in the 
templates, you can write your own "wrappers" around those you need:

Re: Migration dependency not added when field is altered

[Durai pandian]

When you make any changes to the field, AlterField will be added rather
than AddField.

Migration dependency not added when field is altered

[Erin Masatsugu]

If I have this a model in app A:
class AppAModel(models.Model):
name = models.CharField(max_length=50, default="")

and this model in app B:
class AppBModel(models.Model):
name = models.CharField(max_length=50, default="")

and a I add a foreign key to AppAModel in app C:
class AppCModel(models.Model):
my_field = models.ForeignKey(AppAModel, on_delete=models.CASCADE)

the generated migration file correctly adds a dependency from app C to app 
A:
class Migration(migrations.Migration):

dependencies = [
('app_a', '_app_a_migration'),
('app_c', '_app_c_migration'),
]

operations = [
migrations.CreateModel(
name='AppCModel',
fields=[
('id', models.AutoField(auto_created=True, 
primary_key=True, serialize=False, verbose_name='ID')),
('my_field', 
models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, 
to='ncm.AppAModel')),
],
),
]

However, if I then update my_field to instead have a foreign key to 
AppBModel, django doesn't add a migration dependency from app C to app B:
class Migration(migrations.Migration):

dependencies = [
('app_c', '_app_c_migration'),
]

operations = [
migrations.AlterField(
model_name='appcmodel',
name='my_field',

field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, 
to='metals.AppBModel'),
),
]

I saw the response here 
https://groups.google.com/forum/#!searchin/django-users/migration$20dependency%7Csort:date/django-users/-h9LZxFomLU/ry_yeWGfDQAJ
 
so I don't believe this is expected behavior, but can someone confirm?

Thank you!
Erin

RES: IntegrityError: NOT NULL constraint failed

[Samuel Nogueira]

In your Comment model you have a author field wich is a ForeignKey. The error is pointing exactly to that field, since it is a not null field. To overcome this you must pick the ID of the logged user and set the author field with the user ID. You can do that in your views.py the same way as you did in new_comment.post = post, only changing .post for .author and matching it with request.user. the line will look like this new_comment.author = request.user. remember to put it before new_comment.save()  De: sunday honestyEnviado:quarta-feira, 27 de maio de 2020 19:36Para: Django usersAssunto: IntegrityError: NOT NULL constraint failed I try to let user add comments to blog post am making...

Re: Optmized Query

I also know about this concept but I don't how I can achieve it, Could
you give me an example?
Suppose I have:







*class Profile(models.Model):user = models.OneToOneField(
settings.AUTH_USER_MODEL,on_delete = models.CASCADE,
related_name="profile")location = models.ManyToManyField(Location)*


Thank you

Re: Redirect to login page without losing content of form

Consider what will happen if the form is *not* valid, ie. this statement 
returns false:


if form.is_valid():

Remember that functions in Python without an explicit return will 
implicitly return None.


That should hopefully make it clear.

No, you are wrong, and this is explicitly pointed out in the docs

Looking for a solution? Calculating index/offset of a particular record?

[Benjamin Schollnick]

I’m trying to optimize a few different things.

I am looking to try to change this into a more database driven routine, instead 
of having to iterate through each and every record.  While not time consuming 
(overall), I would like to try to make it a bit cleaner…

Effectively I am calculating which record the user is actually looking at in 
the gallery.  The UUID is based into the view, and the view then has to figure 
out it’s image XX out of YYY.

 for counter, data in enumerate(catalog_qs, start=1):
 if str(data.uuid) == e_uuid:
 context["page"] = counter
 break

I generalized it to this:

def return_offset_uuid(sorder, fpath, tuuid):
"""
Fetch specific database values only from the database
"""
entries = 
index_data.objects.exclude(ignore=True).exclude(delete_pending=True).filter(
fqpndirectory=fpath.lower().strip()).order_by(*SORT_MATRIX[sorder])
tpk = entries.filter(uuid=tuuid.strip())[0].pk
count = entries.filter(pk__lte=tpk).count() - 1
#answer = user.answer_set.filter(question=question).get()
# return user.answer_set.filter(pk__lte=answer.pk).count() - 1
return count


Which *seemed* to work, except it didn’t.  Yes, I got results:

>>> return_offset_uuid(0, album, "c0543ce7-d156-430d-b08a-5f7379b6e246")# 1
1
>>> return_offset_uuid(0, album, "519f5b9c-e4f4-44e1-aa82-f36aed98e6a9")# 31
4905
>>> return_offset_uuid(0, album, "754fcb51-c3ad-417d-b317-b86305597ae9")# 61
5044
>>> return_offset_uuid(0, album, "b85f18e0-aa17-4192-9c0f-a363d82fa127")# 91
81
>>> return_offset_uuid(0, album, "fe750266-5fb6-467a-929e-c752fa2091ac")  # 
>>> 121
108
>>> return_offset_uuid(0, album, "51d5ea79-1859-402b-85ff-ae3b2adf7173")  # 
>>> 5535
4885

Looking at it, entry “.jpg” is added, it’ll have a larger PK than “ZZZ.jpg” 
which was added two months ago.

Is there a better way to do this?  I’ll keep the for loop if I have to…

- Benjamin

There might be better ways to do this, but I would override the save() 
method of your model with something like:


def save(self, *args, **kwargs):
self.code = 'BAC{:05}'.format(self.id)
super(MyModel, self).save(*args, **kwargs)

Untested, but hopefully you get the idea.

Kind regards,

Can we use python related api's on the Django templates ?

[ratnadeep ray]

Hi all, 

Currently I am trying to print the type of a variable from the Django 
template html file as follows: 

The type of feature list report for version 
> {%type(version)%} is


For the above, I am getting the following error: 

Invalid block tag on line 9: 'type(version)'. Did you forget to register or 
load this tag?


So what's going wrong here? How can we use the python related api's (like 
type) from the html template files? I think inside the {%  %} we can 
use python related evaluations. Am I right? 

Please throw some lights on this .

Thanks.

Re: function model which generate a code for model field

[Anselme SERI]

Hello,

I will try to explain it to you in the language I understand best and I
hope that you will have an excellent translator to identify me.

english version
What I want to do is fill in the 'code' field of my 'Diploma' template. For
example, the first record of the model will have the value 'BAC1' in
the 'code' field, the second 'BAC2', , 'BAC01653' .
The approach I have chosen to achieve this objective consists in defining a
function in the model which will retrieve the value of the last id of the
last record, increment it then concatenate it to the chain to obtain the
value of the code field of the new recording. code = chain + (lastid + 1)
with chain = 'BAC000 ..'. I hope it's clear now?

french version
Ce que je souhaite faire, c'est remplir le champ 'code' de mon modele
'Diplôme'. Par exemple le premier enregistrement du modèle aura la valeur
'BAC1' dans le champ 'code', le deuxième 'BAC2',,
'BAC01653' .
L'approche que j'ai retenue pour atteindre ce objectif consiste à   définir
une fonction dans le modèle qui va récupérer la valeur du dernier id du
dernier enregistrerment, l'incrémenter puis la concatener à la chaine pour
obtenir la valeur du champ code du nouvelle enregistrement. code = chaine +
(lastid + 1) avec chaine = 'BAC000..'. J'espère que c'est clair maintenant?

Best regards

Anselme S.

Re: Custom Model action in Django Admin

[Anubhav Madhav]

Okay!! I have solved it myself:
the mistake was that 'subscribers' is itself a list, so 'to_email' should 
be 'sub' instead of '[sub]'.

Thank You

Re: Regarding redering data in html templates

[Ifeanyi Chielo]

at the html file of your template folder, use something like
{{table1.skin_care1}}
{{table1.skin_care2}} etc

note skin_care1, skin_care etc are fields in your model table 'table1'

Custom Model action in Django Admin

[Anubhav Madhav]

Hello everyone!!

I have stuck in the middle of my project. Please help.


I have created a custom function within a model, which sends a newsletter 
email to the subscribed users. I registered this model action in admins.py 
, so that I can perform that action using admin panel.

After that, when I go to django admin panel, and perform the action , it 
shows me an error:

ValueError at /admin/blog/post/

not enough values to unpack (expected 2, got 1)


How can I fix this? Please help!!

Lots of examples out there, but here is one:

For working with static files (such as CSS or images), have a look at:
