Re: Django help| Urgent | how to find the frequency of a string for each word using django admin?

2021-07-09 Thread Tree Chip Net

let suppose I have 2 models:
*class String(models.model):*
*string = models.textarea(null = True, blank = True)*
*user = models.ForeignKey(user, on_delete=models.CASCADE)*
*def __str__(self):*
*return self.string*

and


*class Song_Words_Count(models.model):*
*song = models.ForeignKey(user, on_delete=models.SET_NULL)*
*def __str__(self):*
*return self.song*

now what I want to do at django admin side that the string added in
* "String" *model should be saved in Song_Wors_count model and string
should be splitted in a single word and frequency should be counted this
way:

word word_freq
word1 10
word2 15
word3 20

I need Urgent help please.

get_changeform_initial_data with ManyToMany

2021-07-09 Thread Thibault Thomas


Hello,

How can I use admin's get_changeform_initial_data function to prepopulate a 
many to many relationship widget ?

I have the following models in models.py :
___ 
*class Piece(models.Model):*
vehicules = models.ManyToManyField(Vehicule, through=
'AppartenanceVehicule', verbose_name='véhicules')
soustypes_piece = models.ManyToManyField(SousTypePiece, blank=False, 
default=None, verbose_name='sous-types de pièce')

*class AppartenanceVehicule(models.Model):*
vehicule = models.ForeignKey(Vehicule, on_delete=models.CASCADE)
piece = models.ForeignKey(Piece, on_delete=models.CASCADE)
annee = models.PositiveSmallIntegerField('année', blank=True, null=True, 
validators=[MinValueValidator(1900), MaxValueValidator(2100)])

*class SousTypePiece(models.Model):*
# some attributes

*class Vehicule(models.Model):*
   # some attributes
___

I use the following function in admin.py's ModelAdmin for Piece model :

___
*def get_changeform_initial_data(self, request):*
  * if **request.GET.get('vehicule_pk') and 
request.GET.get('soustype_piece_pk'):*
vehicule = get_object_or_404(Vehicule, pk=request.GET.get(
'vehicule_pk'))
soustype_piece = get_object_or_404(SousTypePiece, pk
=request.GET.get('soustype_piece_pk'))
   return {
  'vehicules': vehicule,
  'soustypes_piece': soustype_piece
   }
  * elif request.GET.get('vehicule_pk'):*
   vehicule = get_object_or_404(Vehicule, pk=request.GET.get(
'vehicule_pk'))
   return {
  'vehicules': vehicule,
   }
__

but I can only prepopulate soustypes_piece correctly. I remember I could 
prepopulate vehicules when I didn't use an intermediate model (using 
'through'). This may be why I can still prepopulate soustypes_piece.

Any idea how I can make it work ?

Thanks,

Thibault

Re: Django help| Urgent | how to find the frequency of a string for each word using django admin?

2021-07-09 Thread Sebastian Jung

Hello Peter,

ich would make it with a signal.

Here a another example to use a post save signal:

from django.db.models.signals import post_savefrom django.dispatch
import receiver
class TransactionDetail(models.Model):
product = models.ForeignKey(Product)
# method for updating@receiver(post_save, sender=TransactionDetail,
dispatch_uid="update_stock_count")def update_stock(sender, instance,
**kwargs):
instance.product.stock -= instance.amount
instance.product.save()


Please write me if you don't understand these example.


P.S. i have no idea why you have a foreignkey relation. Why you save
words not in another column in String class?

Regards

Re: Django help| Urgent | how to find the frequency of a string for each word using django admin?

2021-07-09 Thread 'Peter van der Does' via Django users

Overwrite the save method on the String model and when you hit save you
split and save the words in the S_W_C model. This does mean when you
update the String record all the words are added to the S_W_C model as
well, as there is no correlation between the two model you don't know if
that String was already counted.

 If you're using a PostgreSQL you might want to look at using a tsvector
 column instead which will ignore stop words (the, or, of, ...) and map
 lexemes to their number of occurrence and position in the

 efficiently query it for existence of a particular lexeme or multiple 
 of
 them.

 You could then a union of all a user's song lyrics tsvector and
 even apply weights based on their listening frequency or their favorite
 songs.

 Cheers,
 Simon
