No module named _mysql

[Sandeep kaur]

Greetings,
I am using Python3.4 for the Django app on CentOs. The application is
working perfectly fine with runserver, but when it is configured with
apache and wsgi.py, I get this Internal Server error and error long says :

[Wed Sep 16 11:38:30 2015] [error] [client 101.56.225.177]   File

ImproperlyConfigured: Error loading MySQLdb module: No module named _mysql


MySQLdb module is working perfectly fine. I tried to install MySQL-python
and then found MySQLdb doesn't have Python 3 support. Then tried to used
Python -mysql connector but that too gives error.

I don't know why the MySQL is not working with apache.
Your help will be highly appreciated.

I want to have the thumnails of images with the names in the dropdown field
of form. To return the image as foreign key field, I have used  this code :
def __unicode__(self):
image_data =
open("/home/sandy/whats-fresh-api/media/images/download.jpg", "rb").read()
return '%s' % (self.name) + HttpResponse(image_data,

But it give following error :

Your application is not able to find the module hellodjango.wsgi. Did you

When I use $ps -aux command to see which gunicorn program is running. It

new to nginx and gunicorn deployment. Though deployment has been done but
am not able to understand why the changes are not visible and which program
is running which is behind the deployment.

Everything is fine with deployment of project on server with nginx. Its
only with the new app I added to the project which is not working. Do I
need to start the app with gunicorn or something like this?

Deploying Django apps with nginx

[Sandeep kaur]

Hi,
I want to deploy multiple django apps on a server with nginx. When we do it
on apache
we do it in /etc/apache2/httpd.conf and following content :

 WSGIScriptAlias /django /home/sandy/django_app/apache/django.wsgi

 

 Order allow,deny
 Allow from all
 

Thus this app can be accessed by example.com/django or if any other app on
same server then with example.com/django2. How can we do this with nginx?

Your help will be appreciated. :)
Thank you.

still confused with the relations, i.e. one to one, many to one, and many
to many. Will someone please please please explain it to me. How can I use
it? I really need to know

many to one :
This relationship is used as foreign key. In this one table can be used as
a parent for many children.
Eg :

class Manufacturer(models.Model):
# ...
pass

class Car(models.Model):
manufacturer = models.ForeignKey('Manufacturer')
# ...

class Bus(models.Model):
manufacturer = models.ForeignKey('Manufacturer')
# ...

Here there is one base table Manufacturer which acts as base for 2 other
tables.

many to many :
When you want many rows of a table to be linked to many rows of another
table, we use manytomany field.

class Vehicle(models.Model):
   # ..
   manufacturer = models.ManyToManyField(Manufacturer)
For more :
http://charlesleifer.com/blog/describing-relationships-djangos-manytomany-through/

Application : For making checkboxes

one to one :
This is similar to foreign key, except that one parent has only one child.
Conceptually, this is similar to a ForeignKey with unique=True, but the
“reverse” side of the relation will directly return a single object.

class Car(models.Model):
manufacturer = OneToOneField('Manufacturer')
# ...

Hope this helped.

Re: Editing forms in django

That means editing the already saved data?

Assuming you are using a ModelForm, use the instance keyword argument,
and pass the model you are updating.

So, if you have MyModel and MyModelForm, then your code might look like:

my_record = MyModel.objects.get(id=XXX)
form = MyModelForm(instance=my_record)

And then, when the user sends back data by POST:

form = MyModelForm(request.POST, instance=my_record)

Documentation is here:
http://docs.djangoproject.com/en/1.3/topics/forms/modelforms/

Iterating over fields in Formset

[Sandeep kaur]

 I have my code for formset here :

 {% csrf_token %}

{{ FAtestform_formset.management_form }}


{% for form in FAtestform_formset.forms %}
  {% if forloop.first %}
  

{% for field in form.visible_fields %}
{{ field.label|capfirst }}
{% endfor %}
  
  {% endif %}
  {% for students in student %}
  

  {% for field in form.visible_fields %}

{# Include the hidden fields in the form #}
{{ field.errors.as_ul }}
  {{ field }}

  {% endfor %}
  
 {% endfor %}
{% endfor %}




With this I get something like this on the browser :
http://devplace.in/~sandy/screen.png

But the problem with this is that all the fields does not get saved in
the database. Only the last row of the screenshot get submitted. How
can I do it right so that all the multiple rows get submitted at once?

Yes there are barely few changes that need to be made. There is a

The foreign key is by default acessible in the forms in the form of
drop down. You just need to define the form of your model and the in

I haven't used South for complex data migrations, but I think it's
most useful just after (or simultaneously to) doing the schema
migration with South.  In your case, you sound like you haven't done
any real schema migration, more like a reimplementation.

(( unless it is just a change to the application and your talk about
"new application" and "old application" means just that you're not
using any version control system.  in that case, no matter what i
advice here, you're already in deep trouble ))

if you've done a real reimplementation, then I don't think there's any
tool to do much help.  you have to write a third application that
reads data in the old representation and writes in the new one.  and
run that app once.

of course, if both old and new applications are written with Django
and handle data via the Django ORM, then you can do things like:


import oldapp.models
import newapp.models

for oldrec in oldapp.models.MyModel.objects.all():
newapp.models.MyNewModel.create (newfield=oldrec.oldfield,..)


and so on.

I think this will help you :
p = table(material =material, ...[other fields of table to be saved])
p.save()

Here table is your table where you want object value to be saved.

According to me, If that is true then it should not have thrown Import

To install the sitemap app, follow these steps:

   1. Add 'django.contrib.sitemaps' to your

   2. Make sure 'django.template.loaders.app_directories.Loader' is in your

I think you haven't understood what I want. I don't say my code is

help me change it to correct one.
What I want to do :
Get instance of one table, which after editing get saved to some other table.
What I get :
I get values of one table and after editing it get saved to the same table. :(

Editing model instance

[Sandeep kaur]

I edit value of a table using model instance, however after editing I
want the values to be saved in some other table with same structure.
For this to happen I have used following code in views.py :

def editjob(request):
clientjob = ClientJob.objects.get(job_id = query)
if request.method == "POST":
jform = editJobForm(request.POST, instance=job)
sform = editClientJobForm(request.POST, 
instance=clientjob)
if jform.is_valid() and sform.is_valid():
jform.save()
sform.save()
return
render_to_response('tcc/succes.html',context_instance=RequestContext(request))
else:   
jform = editJobForm(instance=job)
sform = editClientJobForm(instance=clientjob)
return render_to_response('tcc/edit_job.html', {'jform':
jform,'sform':sform},context_instance=RequestContext(request))

where :
class editJobForm(forms.ModelForm):
class Meta :
model = EditJob
exclude= ['client','job_no','id']

class editClientJobForm(forms.ModelForm):

class Meta :
model = ClientEditJob
exclude= ['job']

However this code saves the value in same instance itself. What I want
is to get old values from table: Job and ClientJob and then after
editing get saved in tables: EditJob and ClentEditJob.
Is this possible? Your help will be appreciated.
Thank you.

I don't find any errors here. I think you are always getting

When we exclude a field from a form, that field become invisible. But
as we know, that it is mandatory to fill the foreign key value (else
the form will become invalid), so you should by some way give some
value to foreign key field.

I  think you are using old version of Django.
Try this :
python manage.py shell
>>> from django import forms   #input
>>> forms.Form  #input
   #output

If you don't get this output, you are using old version of Django. Use
new version.

Your admin.py file should have this code :

from django.contrib import admin
from mysite.polls.models import Choice


class ChoiceInline(admin.TabularInline):
model = Choice
extra = 3

Conditions in template slows down the software

[Sandeep kaur]

I have used many condition in my templates, in order to filter my
results. My template file uses this code  :

{% for clients in client %}
{% for amounts in amount %}
{% for suspences in suspence %}
{% for tadas in tada %}
 {% for transports in transport %}
 {% if clients.job_no == amounts.job_no%}
 {% if clients.job_no == suspences.job_no %}
{% if clients.job_no == tadas.job_no %}
{% if clients.job_no == transports.job_no %}
  

{{ clients.job_no}}
 {{ clients.date }}
 {{ clients.receipt_no }}
 {{clients.name_and_address}}
{{amounts.field}}
...
...

This code slows down the system to a great extent. Please suggest me
an alternate and better solution.

Saving the form containing checkboxes

[Sandeep kaur]

I want to have checkboxes in my form.  For that I took the table field
as ManyToManyField. When the template renders the form as its models,
it correctly save the values  in database, but when I create the form
with same fields myself i templates, it does not save the values. I
don't know where I am going wrong.
My code is :

views.py->

def search(request):
query =request.GET.get('q', '')
field_list = Material.objects.all()
if query:
material =Material.objects.get(id=request.GET['q'])
test = Test.objects.all().filter(material_id = query)
if request.method=='POST':
form = JobForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
site =cd['site']
test = request.POST.getlist('test')
type_of_work = cd['type_of_work']
profile = form.save(commit=False)
id = ClientJob.objects.aggregate(Max('job_no'))
maxid =id['job_no__max']
if maxid== None :
maxid = 1
else:
maxid = maxid + 1
profile.job_no = maxid
profile.client = request.user
profile.save()
form.save_m2m()
form.save()
return render_to_response('tcc/new_client_ok.html',

form,}, context_instance=RequestContext(request))

form = JobForm()

You are right.
Actually, I want a cart like system. Like in my project's case, if a
client want to test multiple material in one job, it should generate
one bill and receipt. But for each different material, different jobs
are created. So, I thought it could be achieved by storing the session
in which the user logged and then get the bill generated based on that
session.
If you find it a vague solution, do tell the most optimum solution.

Using sessions in Django

[Sandeep kaur]

I am using session foreign key in my table.

class ClientJob(models.Model): #models.py
 .
 sess = models.ForeignKey(Session)

And in order to save its value in database, I used ,.

def add_job(request)  #views.py
 ...
 if not request.session.exists(request.session.session_key):
request.session.create()
 profile.sess = request.session.session_key
 profile.save()

But when I execute my form and click on submit button, I get error as :

```Cannot assign "'b593c61453d7aad199078c66b9ad6b30'":
"ClientJob.sess" must be a "Session" instance.

I am a bit unclear about using sessions in django, so be a little elaborative.

Thank you.

Why don't you use sessions for the same. That is, in a session find
number of clicks on the pages by a user, then save it in database.
Then just get the page that has maximum clicks, that will be the most
popular page.
Just a wild idea.

This code is useful for bringing the drop down options from the database.
But I want to have the dynamically filtered options from the last
selected options without refreshing the page.

I have used the following code but it is not working according to my
requirement.
Please check and point out where I am making mistake.



from django import template

register = template.Library()

@register.inclusion_tag("field_test_select.html")
def field_test_select(request):
field_list = Field.objects.all()
return render_to_response('field_test_select.html', {'field_list'
: field_list}, context_instance=RequestContext(request))

def all_json_tests(request, field):
current_field = Field.objects.get(id=field)
test = Test.objects.all().filter(field=current_field)
json_test = serializers.serialize("json", test)
return HttpResponse(json_test, mimetype="application/javascript")



(r'^add_job/$', 'field_test_select'),
(r'^field/(?P[-\w]+)/all_json_tests/$', 'all_json_tests'),








Select a field
{% for field in field_list %}
{{ field.name }}
{% endfor %}


Select a test



$(document).ready(
 function() {
 $("select#field").change(function() {
 if ($(this).val() == 'Z') {
 $("select#test").html("<option>Select
a test</option>");
 $("select#test").attr('disabled', true);
 }
 else {
 var url = "/field/" + $(this).val() +
"/all_json_tests";
 var field = $(this).val();
 $.getJSON(url, function(tests) {
 var options = '<option
value="Z">Select a test</option>';
 for (var i = 0; i < tests.length; i++) {
options += '<option value="' +
tests[i].pk + '">' + tests[i].fields['name'] + '</option>';
 }
 $("select#test").html(options);
 $("select#test
option:first").attr('selected', 'selected');
 $("select#test").attr('disabled', false);
 });
 //}
 });


 $("select#test").change(function(vent) {
 if ($(this).val() == -1) {
     return;
 }
 myAwesomeFunctionToCallWhenAtestIsSelected();
 });
 });
}

Django TypeError

[Sandeep kaur]

I want to have different views for my application for different types
of users. For this I have this code for my views.py file :

def index1(request):
u = User.objects.all()
if u.is_staff ==1 and u.is_active == 1 and u.is_superuser == 1:
return render_to_response('tcc11_12/index1.html',

elif u.is_staff == 1 and u.is_active == 1 and u.is_superuser == 0:
return render_to_response('tcc11_12/index2.html',
context_instance=RequestContext(request))
else:
return render_to_response('index3.html',
context_instance=RequestContext(request))

But it gives TypeError as :
 "cannot convert dictionary update sequence element #0 to a sequence"

Is there anything wrong in above code?

If you want a counter in database, you can make it auto-increment.
Like I want job_no as a counter field in a table, then in models.py, add this :

job_no = models.AutoField(primary_key=True)

But if you want the counter in tables in the template file then add
{{forloop.counter}} as your table field.

Correct me if I am wrong anywhere.

Database Query in Shell

[Sandeep kaur]

I have a table Amounts which has 2 columns field and other_field.
These columns are filled in such a way that either other_field is null
or other_field = field.
I want to make a database query such that

if field == other_field :
   field = "OTHER"
else:
   field = field

That means the entries in table where 2 columns are equal, there field
should be assigned a string  "OTHER" and other_field should remain as
such.
How can I give such query in shell.

Implementing Foreign Key without admin interface

[Sandeep kaur]

I am using forms, to make the entries from the user. But when it comes
to using foreign key in a table and then making entries to it, I am
unable to do so.

models.py:

 class ClientJob(models.Model):
"""
:ClientJob:

ClientJob Class is define all field reqiued to submit detail about new 
Job.

"""
job_no = models.AutoField(primary_key=True)
receipt_no = models.CharField(max_length=15, editable=False)
...

 class Amount(models.Model):
id = models.AutoField(primary_key=True)
job_no = models.ForeignKey(ClientJob)
.

and my views.py is

 def report_calculation(request):
id = ClientJob.objects.aggregate(Max('job_no'))
maxid =id['job_no__max']
if request.method == 'POST':
form =AmountForm(request.POST)
if form.is_valid():
cd = form.cleaned_data
job_no_id = client.job_no
...
   form.save()
   return
render_to_response('automation/job_ok.html', {'form': form,

form = AmountForm()

Re: Views in django

That will be applicable if I want to his for only 1 table's entry.
But here I have views as :

cd = form.cleaned_data
name_and_address = cd['name_and_address']
title = get_object_or_404(Variable, pk='1')
sign = get_object_or_404(Variable, pk='3')
from TCC11_12.automation.choices import *
client =
ClientJob.objects.filter(name_and_address=name_and_address)
amount = Amount.objects.all()
suspence = Suspence.objects.all()

and for this I have template as :

   {% if client %}
{% for clients in client %}
{% for amounts in amount %}

 {% if clients.job_no == amounts.job_no %}

 {% if clients.name_and_address == clients.name_and_address %}

{{ clients.receipt_no }}
 {{ clients.date }}
{{amounts.total}}
{{amounts.net_total}}
{% endif  %}

{% endif  %}

{% endfor %}

{% endfor %}
{% endif %}


When all this is applied, it creates a view out of 2 tables i.e Amount
and ClientJob without using foreign key. Now I want to have sum of the
total and net_total fields for the views generated.

Views in django

[Sandeep kaur]

Can I apply some operations on the views ( of database) that are
created by me?  Eg: to do sum of some filtered entries. If yes, then
how?

Django - filters

[Sandeep kaur]

Hello all,
In my django application, all the data of different clients are
entered. Sometimes data of even same client is also entered. Now what
I require is to get all the data of the client when it asked for.
The views I used is:

  def old_client(request):
   if request.method == 'POST':
   form = OldClientadd(request.POST)
   if form.is_valid():
   from TCC11_12.automation.functions import *
   cd = form.cleaned_data
   name_and_address = cd['name_and_address']

   title = get_object_or_404(Variable, pk='1')
   sign = get_object_or_404(Variable, pk='3')
   from TCC11_12.automation.choices import *
   client =
ClientJob.objects.filter(name_and_address=name_and_address)
   amount = Amount.objects.all()
   suspence = Suspence.objects.all()
   total_temp = Amount.objects.aggregate(Sum("total"))
   total  = int(total_temp['total_sum'])
   net_total_temp =
Amount.objects.aggregate(Sum('net_total'))
   net_total= int(net_total_temp['net_total__sum'])
   template ={'form':form,
'total':total,'title':title ,'sign':sign, 'net_total':net_total,
'client':client,'amount':amount,'suspence':suspence,'name_and_address':name_and_address
,}
   return
render_to_response('automation/oldclient.html',locals(),
context_instance=RequestContext(request))
   else:
   form = OldClientadd()
   return render_to_response('automation/client.html', {'form': form},
context_instance=RequestContext(request))

Here I get filtered the data of the client I require, from amount and
client  table. But when I go for the sum, it add all the data in
amount field without providing any filter.

Is there any way to find aggregate sum of only those amounts that are
previously filtered ?
I cannot give filter on amount as name and address field is not there
in Amounts table.

This can be done by simply adding your new field in list display under
User Profile of admin.py file. And by doing this you will get your new
field in admin.
