djngo unittest to use "real" database.

[django-newbie]

Hi All,

I am currently writing test cases for views, Which eventually uses database 
also.
By default a test database is being created and removed after test are run.

As the database itself is development database, I don't want my test to 
create a separate db but use exciting only.
Also I will like to bring to your notice, that in my environment, database 
are created and provided and django can't run migration or create database.

Regards,
Arjit

Re: How models.Manager is working behind the scene and calling different serialize methods?

[django-newbie]

Ohk, I got it now..
Thanks for clarifying this.

My further doubts in continuation of this are.

1. For confirmation, ModelName.objects.all() calls get_queryset() method, 
while ModelName.objects.get calls get() method internally.

2. In above code to override default serialize method of BasicUserUpdate 
for get_queryset() method, 
We have to do 2 things.
1. Inherit default models.Manager and override get_queryset() method.
2. Inherit  models.QuerySet and override default serialize method.

Honestly it seems overkill for this problem.
Can u please suggest alternative straight forward way to do it in model 
only.

How models.Manager is working behind the scene and calling different serialize methods?

[django-newbie]

Hi, 
I am new to django and going through a tutorial and now confused with one 
particular implementation.

models.py

import json
from django.core.serializers import serialize

from django.db import models
from django.conf import settings

# Create your models here.


def upload_update_image(instance, filename):
return "updates/{owner}/{filename}".format(owner=instance.owner, 
filename=filename)

class UpdateQuerySet(models.QuerySet):
 
def serialize(self):
print("UpdateQuerySet serialize")
print(self.values("owner", "content", "image"))
list_values = list(self.values("owner", "content", "image"))
return json.dumps(list_values)


class UpdateManager(models.Manager):

def get_queryset(self):
print('get_queryset method')
return UpdateQuerySet(self.model, using=self._db)


class BasicUserUpdate(models.Model):
owner = models.ForeignKey(settings.AUTH_USER_MODEL,on_delete=models.CASCADE)
content = models.TextField(blank=True,null=True)
image = 
models.ImageField(blank=True,null=True,upload_to=upload_update_image,)
updated = models.DateTimeField(auto_now=True)
timestamp = models.DateTimeField(auto_now_add=True)

def __str__(self):
return self.content or ''

objects = UpdateManager()


def serialize(self):
print("BasicUserUpdate serialize")
try:
image = self.image.url
except:
image = ""
data = {
"content": self.content,
"owner": self.owner.id,
"image": image
}
data = json.dumps(data)
return data

  
views.py

from basic.models import BasicUserUpdate
from django.views import View
from django.http import HttpResponse


class BasicUserUpdateListView(View):
def get(self, request, *args, **kwargs):
qs = BasicUserUpdate.objects.all()
json_data = qs.serialize()
return HttpResponse(json_data, content_type='application/json')

class BasicUserUpdateDetailView(View):

def get(self, request,id, *args, **kwargs):
qs = BasicUserUpdate.objects.get(id=id)
json_data = qs.serialize()
return HttpResponse(json_data, content_type='application/json')

]


*At run time calling ListView, get below print messages*
get_queryset method
UpdateQuerySet serialize

*At run time calling DetailView, get below print messages*
get_queryset method
BasicUserUpdate serialize


*How Django is identifying which serialize method to be called? *

Recommend a way to add my own class into DjanGo

[Django Newbie]

Hey guys,

I want to create a custom class with methods I will be able to access 
everywhere in my Views.

For example a class that add numbers after declaring it somewhere in 
Django. 
*MyNumber = new GenNumberClass()*
*MyNumber.setNumbers(1,2)*
*result = MyNumber.getAddedResult()*

Please point me in the right direction where I can declare classes and 
reuse them. Any recommendations will be welcome.

Thanks.

WSGIScriptAlias / /home/user/python/djcode/cfServer/apache/django.wsgi

Hi Tom,  Jani,

Currently struggling to compile mod_wsgi, or more specifically a shared 
library version of python - something to do with mismatched 32/64 bit 
libraries I think.

Here's an extract from httpd.conf.

RewriteEngine On
RewriteRule ^.*/cfServer/(.*)$ /cgi-bin/django.cgi/$1 [PT]

Options ExecCGI
AddHandler fcgid-script .cgi
# AddHandler cgi-script .cgi
Require all granted


and the relevant django.cgi

#!/usr/local/bin/python
from FcgiWsgiAdapter import list_environment, serve_wsgi

import os, sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'cfServer.settings'
os.environ['ORACLE_HOME'] = '/oracle/11gStdEd'

from django.core.handlers.wsgi import WSGIHandler

# use this to test that fastcgi works and to inspect the environment
# serve_wsgi(list_environment)
# use this to serve django
serve_wsgi(WSGIHandler())

The "FcgiWsgiAdapter" referred to came from 
djangosnippets.org
.

As to error logs, as I mentioned in the original post I don't see anything 
added to any logs when this happens and there is only a warning about the 
ssl library when apache is restarted.

Regards, ADN

Bump  I've had no luck with this and would still appreciate some 
pointers! I've tried re-arranging the order of statements in my model code 
without any improvement.

Problem with tuncated Admin pages in apache + mod_fcgid

[Another Django Newbie]

Hi,

I've just started playing with django this week and was following the
example in the Django Book.

I created an example of my own, based on the models.py in the book and
tested it with manage.py runserver. All worked OK, but when I try it
in apache one of my admin pages is truncated - a number of fields are
left off and there is no Save button. The exact number of fields
truncated depends on whether I use Add from the main page or from the
Add page of another field (so that the affected page is a pop-up)

Apache 2.4.1
mod_fcgid 2.3.6
django 1.3.1
Python 2.7.2
cx-Oracle 5.1.1

Has anyone seen this behaviour? I've looked in apache and django logs
but don't see anything recorded when the page loads. Any ideas greatly
appreciated.

Thanks.

What am I doing wrong with this URL Pattern

[Django Newbie]

Hi,

I am trying to figure out a way to call a function depending on the
parameter in the URL.

Example.
url(r'^People/Info/(?P\d+)/$', 'iFriends.People.views.details'),
url(r'^People/Info/(?P[a-z]{3})/$',
'iFriends.People.views.detail_name'),

It works with numeric value.  if I use "http://localhost:8000/
People/Info/1/"

but not with  if I use http://localhost:8000/People/Info/Jan/

probably something small but still leaning.

user_id in admin pages

[Django Newbie]

This is probably an easy one, but I've tried what make sense to me with 
not success.  What I want to do is in my admin pages, use the User 
module and enter the the user_id of whoever is logged in to add an entry 
in one of my foreign key tables.

How can set a field equal to the user_id to be entered into the db?

Example:
Models:
from django.db import models
from datetime import datetime
from django.contrib.auth.models import User

RATINGS = (
   ('1','1'),
   ('2','2'),
   ('3','3'),
   ('4','4'),
   ('5','5'),
)

class Recipes(models.Model):
  recipe_name = models.CharField(max_length=200)
  ingredients = models.TextField()
  instructions = models.TextField()
  image = 
models.ImageField(upload_to="/home/dave/dinnertools/image_upload",blank=True)
  entered_by = models.ForeignKey(User,blank=True)
  date_entered = models.DateTimeField(auto_now_add=True,blank=True)

  def __unicode__(self):
return self.recipe_name

class Rating(models.Model):
  recipe = models.ForeignKey(Recipes)
  rating = models.IntegerField(choices=RATINGS)
  user = models.ForeignKey(User)

class DishCategory(models.Model):
  category_name = models.CharField(max_length=255)

class RecipeCategory(models.Model):
  category_name = models.ForeignKey(DishCategory)
  recipe = models.ForeignKey(Recipes)

class MyRecipes(models.Model):
  recipe_id = models.ForeignKey(Recipes)
  user = models.ForeignKey(User)

*
admin.py:

from dinnertools.recipes.models import Recipes
from dinnertools.recipes.models import Rating
from django.contrib.auth.models import User
from django.contrib import admin

class RatingChoices(admin.StackedInline):
  model = Rating
  extra = 1

class RecipeAdmin(admin.ModelAdmin):
  fields = ['recipe_name','ingredients','instructions','image']
  inlines = [RatingChoices]
  list_display = ('recipe_name','entered_by','date_entered')
  date_hierarchy = 'date_entered'

admin.site.register(Recipes,RecipeAdmin)

What I want to do is in RecipeAdmin add something like:
  entered_by = User.user_id

So how can set a field equal to the user_id to be entered into the db?

Thanks.

Re: Can javascript call a python script?

[Django Newbie]

With AJAX you can.  Javascript is interpreted by the browser, and you 
want to call a serverside script.  Or you could do it as a form 
submission, but I assume you want it to happen without refreshing the 
page, so AJAX is how you would do that.

rendering DB text in template

[Django Newbie]

So I have some text fields in the db that have some embedded html in the

The text fields are recipe.ingredients and recipe.instructions



   Recipes 
  
.RecipeName{
  font-size: large;
  font-weight: bold;
}
.Recipe{
   width: 700px;
   margin-left: 20px;

function toggle(id) {
  var e = document.getElementById(id);
  if (e) {
e.style.display = e.style.display == 'block' ? 'none' : 'block';
  }
}
  


{% if recipe_list %}

{% for recipe in recipe_list %}
  
 {{ 
recipe.recipe_name }}
  
 

  {{ recipe.ingredients}}


{{ recipe.instructions}}

 
{% endfor %}
 


{% else %}
No recipes are available.

Apache Setup

[Django Newbie]

Hi Everybody,

Django newbie here.  I'm trying to get it to work under apache with 
mod_python on a freebsd server but running into problems.  I searched 
the archives and found similar things, but I tried all the suggestions 
and still no luck.

The error:

#

DB connections of course work outside of the apache/mod_python 
environment.  Also I would expect some temporary file to be unpacked in 
the /www/htdocs/egg_cache directory, but I don't see any.  The 
permissions on the egg_cache directory are such that apache should be 
able to write to it.

Any ideas?  I assume I need the extra setup related to egg file since 
the MySQLdb module has some egg files related to it.  Please let me know 
what I'm missing.

Thanks,

Yours truly, django newbie.
