Re: Adding a verbose_name to id field

Mike,

I tried id = model.AutoField(verbose_name=”Ticket #”).  Migrate didn’t 
like it – can’t have duplicate primaries.  I suspect this is because 
the Bug model already exists.


What I am trying to achieve is an auto-increment field whereby every 
time a user logs a bug/suggestion/comment it writes a unique ticket 
number in the background, which is used as a reference for subsequent 
actions like Fixed, Close, WiP, etc.  and as a ForeignKey in the 
Comment model.   I couldn’t find anything meaningful for this 
functionality and so thought that the ‘id’ is already fit for purpose, 
but merely requires an explanatory field text.




I think Jason is correct. The id field belongs to the DBMS and 
theoretically should never carry any human or real world meaning.


You would be better having an auto-incrementing field called "ticket" or 
similar


If you really must use the id field you can supply the model with your 
own id field (that's covered somewhere in the docs) with whatever name 
suits.


Cheers

Mike




Make sense?

I imagine you need to specify the id field in your model and give it a 
verbose name.


This is an unusual requirement. Why do you want to do such a thing?

Using Sqlite3 & Django 3.0.2 - I have searched high and low, but can’t 
find a way to add a verbose name to the id of a model.


Anyone have ideas, please?

Sounds to me you'd like a separate auto-increment field?

Re: is there a WYSIWYG for Django

2020-02-08 Thread Bill Freeman

That's the plan.  It's what I though you meant by WYSIWYG.  Fiber is nice
because they don't have to understand a back end interface; you just edit
from the page that you want to change, edit a particular element of it,
which client's have an easier time with.  But there still has to be
something that lets you edit HTML straightforwardly, and that needs to run
in the browser for responsiveness.

Re: Adding a verbose_name to id field

2020-02-08 Thread Bruckner de Villiers

Mike,

I tried id = model.AutoField(verbose_name=”Ticket #”).  Migrate didn’t like it 
– can’t have duplicate primaries.  I suspect this is because the Bug model 
already exists.

 

What I am trying to achieve is an auto-increment field whereby every time a 
user logs a bug/suggestion/comment it writes a unique ticket number in the 
background, which is used as a reference for subsequent actions like Fixed, 
Close, WiP, etc.  and as a ForeignKey in the Comment model.   I couldn’t find 
anything meaningful for this functionality and so thought that the ‘id’ is 
already fit for purpose, but merely requires an explanatory field text.

 

Make sense?

I imagine you need to specify the id field in your model and give it a verbose 
name. 

 

This is an unusual requirement. Why do you want to do such a thing?

Using Sqlite3 & Django 3.0.2 - I have searched high and low, but can’t find a 
way to add a verbose name to the id of a model.

Anyone have ideas, please?

Thanks Fiber looks better. But you did say you use mostly TinyMCE. I

Can anyone help me out. Many thanks!



The error clearly indicates what is wrong. You have a syntax error 
because you don't use the correct syntax for importing modules. This was 
the best help I could find:


https://www.tutorialspoint.com/How-to-use-multiple-modules-with-Python-import-Statement

This is extremely basic Python knowledge. I suggest you start out by 
learning some basic python before diving into Django. Otherwise you'll 
spent a lot of time dealing with very basic mistakes like this.


Kind regards,

Kasper Laudrup

Contractions in Django 3.0 and Django 2.2

2020-02-08 Thread One Above All

i am working on a project which is adding support for Django 3.0. While 
doing so, I came across ticket # 30400 
https://code.djangoproject.com/ticket/30400 after which contractions were 
rewritten. I am writing a test which should work with both Django 3.0 and 
2.2. I have to assert error_messages 
in django.contrib.auth.forms.SetPasswordForm like below

self.assertIn("The two password fields didn’t match.", 
> str(response.data['new_password2']))


How can I make this work in both versions of Django ?

Thanks and Regards,
Gagan Deep

Re: Trie Data Structure

2020-02-08 Thread onlinejudge95

I am ready to answer your question, but not here it's a Django User's
Group. The question you are asking is about implementation of an algorithm
which is language agnostic. Technically, it shouldn't be asked in the
Python Mailing list too.

Keep a watch on your inbox though. :)

Thanks,

Trie Data Structure

class TrieNode():

self.children = defaultdict()
self.terminating = False


class Trie():

def __init__(self):
self.root = self.get_node()

def get_node(self):

root = root.children.get(index)

root.terminating = True

def search(self, word):

t = Trie()
for word in strings:

Could anyone tell me,How Inset function is working here? actually I'm not
able to track it. Specially if index is alerady available in root.children
then how it is creating an another TrieNode object.

Thank you in advance

How to fill the form field with the data based on drop down selection of another form field using ajax request

2020-02-08 Thread Dilipkumar Noone

Dear group,

I am Django learner.

I have two models.

1. ModelRegister 
2. ModelGSP

ModelRegister returns model_name.
ModelGSP has a foreignkey to ModelRegister.

When we select a particular model from a ModelGSP model,i want to fill a 
field in ModelGSP with the data for a selected model when ajax request is 
made.

Input data and expected result shown in screen shot below.

*currently when i select any model from RegisteredModel, none of the data 
is populated in get_model_nos_for_modelname field.*

*Please correct me if i am doing any mistake and how to proceed further.*

Below is my code snippet :
