Job board app based in django

[Simon A]

hey guys,

I would like to develop a job board app based in django. I was wondering if 
there is already an available job board app based in django like 
jobberbase. There is a jobberbase clone made from django but its version 
too old already.

thank you,
Simon

Re: [Urgent] 500 when requesting a file from browser.

[Simon A]

On the last part of your stacktrace, there is a section

File "/usr/lib/python3.6/wsgiref/simple_server.py", line 35, in close
self.status.split(' ',1)[0], self.bytes_sent



could you please check this line out? 

you can try to print what is *self.status *to check what it is trying to 
split

Re: How to store a bank account number generated into a model field

[Simon A]

I think the except block won't trigger since if the code 
Profile.objects.get(user=request.user) does not get any results, it will 
return a null result, not throw exception.

instead of exception handling, just check if the return value is null or not

Can you please recommend me a proper way to deal this?

There are problem N clones of job boards built with django, this shouldn't
affect your decision to create one.

Question about makemigrations

[Martin Kong]

Hello
I am new to django, and i am following the tutorial provide in github, from
the tutorial.
The tutorial I am following is
https://github.com/django/django/blob/master/docs/intro/tutorial02.txt

and  start from 227, it shows the following instructions:

.. console::
$ python manage.py makemigrations polls
You should see something similar to the following:
.. code-block:: text
Migrations for 'polls':
polls/migrations/0001_initial.py:
- Create model Choice
- Create model Question
- Add field question to choice
However, after following the steps
I'm missing the last sentence (Add field question to choice) .

The below is what i had written in model.py, did i make something wrong?

Thanks

from django.db import models

class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')

class Choice(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE)
choice_text =  models.CharField(max_length=200)
votes = models.IntegerField(default=0)Thanks

Re: Question about makemigrations

[Rob W]

"Migrate is basically the old syncdb but it takes into account all the 
migrations made by makemigrations. You should run the command -migrate- after 
adding a new app under the INSTALLED APPS section in the settings.py file in 
order to synchronize the database state with your current set of models.”

Re: Can we create a Rest Api in Django which can able to communicate with multiple databases(Relational, Non relational) dynamically. If yes please recommend me a way to do that

[Chetan Ganji]

If it is one time selection like storing in a user level settings, you can
store the database to use in user model
i.e. you have to customize default Usermodel in django and add one extra
field to store the db type of the current user.

Then access the right db

Author.objects.using(request.user.database).all()

OR

Author.objects.using('mysql').all()

Author.objects.using('postgresql').all()

You might have to use the database routers also. It depends on your
detailed requirements.

Re: [Model, ORM] Disabling a field before actually removing it

[George Silva]

The answer is indeed to split this into steps.

First step is to allow the field to be nullable if it's not already. Deploy.

Then you create a new deploy (not PR) that stops using the field altogether
from all the codebase. You can remove the reference to the field or comment
it out. Do not `makemigrations`. Deploy.

Create the last step, which is the migration to drop the field from the
database.

Hi Lutalo,

Could you also share the stacktrace of the error and when it happens? It
would help us decipher what's really going on in relation to what you're
trying to do.

Re: invalid literal for int() with base 10: ''

Does the stack trace mention a template variable name?  It looks like a
template variable that is expected to have integer value is not properly
initialized.

Would you be able to copy and paste the stack trace here? Without that,

Re: invalid literal for int() with base 10: ''

[Héctor Alonso Lozada Echezuría]

Apparently product_id has no value

product_id = request.POST.get("product_id")
print(product_id)
print(type(product_id))

Re: invalid literal for int() with base 10: ''

[Lutalo Bbosa joseph]

am trying to figure it out but when i
print(product_id)
print(type(product_id)) i get this output
1
, so probably its because i cant iterate over a string but am
still failing to figure it out

Update using columns from subquery

[Dean Rabinowitz]

I'm new to the community (this is my first topic here) so I apologize if 
I'm breaking any rules with this post.

My goal is to update a table in my Postgres db using the values from a 
queryset only where some of the values are equal to the columns in my 
table. Essentially, I'd like to do the following:

UPDATE schema.table t1 SET t1.value = t2.value FROM ( SELECT id1, id2, value 
FROM 
does_not_matter ) t2 WHERE t1.id1 = t2.id1 AND t1.id2 = t2.id2 In this 
example, t2 represents my queryset. It can contain potentially hundreds of 
thousands of rows (distinct on (id1, id2)).

Is there any way to accomplish this using the django ORM? I'm using version 
1.11

[novice question] Render a list of objects

[Sudeep Gopal]

Hello, 

I am new to django. 

I am using django forms in my project and I am not using django models. 

>From the user,  my django form asks for 4 inputs :- signal_to_noise_1 , 
signal_to_noise_2, bandwidth1 and bandwidth2. 

Based on these values I use my  look up table and I create a results which 
are 2 lists of records.
 Each list has approximately 40 to 50 records. Each record has 8 fields. 
(field1,...field8) ...

*Each list *looks like this (if my description is not clear) field1 is 
unique. 

field1  field2  field3 



field8











Both the lists (with each list having about 50 records) are in my django 
view. 

>From what I read online, I can use the render() method which has a *dictionary 
*called context. (
https://docs.djangoproject.com/en/2.2/ref/templates/api/#rendering-a-context
)

I am not sure how to convert these list of record objects to this 
dictionary format which has {"name":value} pair. 

Even the django tables requires it in the dictionary format.

The nearest thing which I found was 
https://stackoverflow.com/questions/9388064/django-template-turn-array-into-html-table
 

But I did not understand what exactly the below syntax does and how I can 
customize it to my usecase any input would be greatly appreciated ...


  {% for r in results %}
{% cycle '' '' '' '' %}
  {{r.content}}
{% cycle '' '' '' '' %}
  {% endfor %}
