django query, order results such that th128 > th99

[gintare]

Is it possible to order the query result strings in such a way that th128 
string would be first comparing to th99.
The query results contains 128 items in format: "th"+number. For instance, 
th1, th2, ...th80, ..th99, th100, th128.
Than i order results, they go in the following order, th1, th10,th100, 
th101,th102,... th11,th110, ... th2, th20, th21,th22,.. th9,..th99.
Thus i am not able to get the largest result, which is th128. I am getting 
th99 instead.

def temp(request):
query = request.GET.get( 'q','')
#a=Aref5.objects.filter(Rname__contains='book').count()  #finds128

a=Aref5.objects.filter(Rname__contains='book').order_by('-Rname')[0:1].get() 
#gets aref5 object
print(a.Rname) #prints th99 instead of th128, which logically is larger
return render_to_response('Ath.html', {"query": query})

Admin, Save

[gintare]

I am not able to save changes through Admin page in the model
instance.

The Admin page has such levels:

Project>> Model >> Model Instance.
The option save is at Model and Model Instance levels.

I can save changes only in the last Model Instance level.

I would like to be able to save changes at Model level, where i can
edit tens of Instances and later press 'Save' for all of them.

Maybe it is a bug, since the button "save exists", but it is not
working.

python, django, regex, θæŋkfəli

[gintare]

This is corrected question. The first time it was submitted on
2011.11.22 nd.

I am not able to save string with special characters, such as θæŋ
after re.search(string).
#saving to the model Textfield does not work. Instead of θæŋkfəli, i
am getting shown "\xce\xb8\xc3\xa6\xc5\x8bkf\xc9\x99li" in Admin page.
Is it error in re.search?
Should i use special parameters during model field saving or in Admin
entry displaying?

string which i wan to save exactly as it is, Django saves it correctly

## ***AFTER TRYING TO SEARCH part of unicode string linesu for

Re: output as input *.html

[gintare]

I mean maybe there is some special function in Django
which display any model field as input field  in *.html.

I mean instead of generating simple text in *.html
{{ model.fieldValue_which_is_displayed_as_text }}
generates editable *.html
[[  
model.fieldValue_which_is_possible_to_edit_and_is_saved_BACK_automatically_to_model

model field assignment

[gintare]

I would like to remove multiplicative items in several fields of the
model.
I do not know how to save changes:

 for Lists in [a.SynGREn, a.SynGREnn]:
...
.. make changes in field by editing Lists, i.e. cropping part of
text: changed_text=crop(Lists, words)
...Lists=changed_text
... a.save()

HOW to save these changes to model back?
#  a.save() does save changes  for model field a.SynGREn ,
a.SynGREnn


#Suppose threre is a model GRE, with Char fieldsSynGREn,
SynGREnn

for Lists in [a.SynGREn, a.SynGREnn]:
strc=''
List=Lists.split(',')
for item in List:
if (len(item)!=0):
searchs='\s+'+item+'\s+'
if ( re.search(searchs, strc)==None ):
strc=strc+', '+item+' '
Lists=strc
a.save();
#saves changes only for variable Lists, not for model field a.SynGREn
or a.SynGREnn

output as input *.html

[gintare]

Now if i filter out and display model objects they come as a text
information.
I can only read it. It is not possible to make and save changes
directly in *.html.


Maybe there is some function which i overlooked by reading
documentation, which displays model fields as input with initial
values from database.

This is possible in admine site.
Maybe it is also possible in custom template.

Now i am using plain html syntax an tag dictionaries to assign name
and value for radio, check boxes, text areas, buttons...

where is a mistake in radio buttons

[gintare]

*.html


{% csrf_token %}


starts
ends
contains
equal


''''''''''''''''''''''''#
views.py

rstartsLkIn, rendsLkIn, rcontainsLkIn, requalLkIn =
request.POST.get('rstartsLkIn','')  ,
request.POST.get('rendsLkIn','')  ,
request.POST.get('rcontainsLkIn','')  ,
request.POST.get('requalLkIn','')

 if (rcontainsLkIn)... gives none  although it is already preselected
initially.

How i should read value from radio buttons?
Check-boxes works perfectly.

Re: different length queries

[gintare]

Thanks a lot for the answers!
I did not found that it is possible to use dictionaries and lists in
query.
In the end i used raw function to form string according form input.
Lists and Dictionaries is much better way, since i am not tied to
certain database.

different length queries

[gintare]

Hello,

Could you please advice if it is possible and where i could read OR at
least that keywords should search for the following question.

Is there a way to submit List =  [Q(word__starts='search_input'),
Q(date='search_input') ,]
to model.objects.filter (List).
How i have to formulate such list?

My query may contain from 1 to tens of restrictions
i.e. query with  1 item:
object. all.filter(Q(word__starts='search_input'))
versus query with 3 items:
object. all.filter( Q(word__starts='search_input')  ,
Q(date='search_input')  ,  Q( smth_else='search_input')   )

I know only programming basics and in order to execute selected
queries i have to write many if sentences.
i.e. query with  1 item:
if (word):  object. all.filter(Q(word__starts='search_input'))

versus query with 3 items:
if (word & date & smth_else ): object.
all.filter( Q(word__starts='search_input')  ,
Q(date='search_input')  ,  Q( smth_else='search_input')   )

Number of combination is very huge. Is there a way to submit a List
containing [Q(word__starts='search_input'),
Q(date='search_input') ,]
How i have to formulate such list?


P.s. In sqlite3 i can make a string in for cycle:

##for key in DSearch.keys():
##str2=str2+' ( '+str(key)+' LIKE '+item+')
AND'
## instead of LIKE i use one more if-elif cycle for search_method
starts, contains, ends, equal
##if (str2!=''):
##str3=str2[:-4]+' );'
##cursor.execute(st3);
##transaction.commit_unless_managed()
##ans=cursor.fetchall()

I would like to use Django.

django OneToOne field may not be NULL

[gintare]

Hello,

I would like to ask how i should correctly deal with OneToOne (OTO)
relation field .
When i create object from model with OTO fields i do not want to
assign any model to them. Maybe i will do in future when appropriate
object will appear.

Django do not let me to have not assigned OTO fields. At least i have
to create empty OTO object.

class Word(models.Model):
WwLksOTO=models.OneToOneField(Lks, related_name='WwmainLks',
blank=True, default='')## for input, goes to LinkModel and WordLinkMM
field

def save(self, *args, **kwargs):
if not self.id:
self.WwLksOTO=Lks.objects.create()
super(Word, self).save()

Now i just create LksOTO in save, since otherwise django generates the
error.

memory, time, 1000 lines model or 100 models with 10 lines

[gintare]

I have an object, which described in one model has 1000 lines.
Another way is to split object to 100 pieces with 10 lines length.

In both cases the 1000 lines will be filled in memory.

I am going to create tens of thousands entrances of this object.

If the object model will be split to 100 models, than the number of
entrances in database increase 100 times.

What is better performance of the Django, Sqlite3.
Have 20.000 entrances in the table with 1000 columns
or 2.000.000 entrances in the table with 10 columns

Is it possible by making small change to resolve the error below:

query did not work

[gintare]

would like to post one bug, since i was sitting 4h on it

For some reasons query did not work.
In the end appeared that it depends on how urls.py are formulated:

urlpatterns = patterns('',
   (r'^searchbooks','Finnish2.Fin.views.searchbooks'),   # page
http://127.0.0.1:8000/searchbooks is displayed, query works
   (r'^SB','Finnish2.Fin.views.searchbooks'), # page 
http://127.0.0.1:8000/SB
is displayed, query does not work, already print query statement in
views.searchbooks gives empty string
)

Maybe smbd can comment why this happens.

to iterate over two lists simultaneously in *.html

[gintare]

Hello,

I am sorry for asking a simple question.
(I read other answer bout iteration in several items in this user
group - they are too complicated for me. I have no time to study
Django deeper. )
I want to iterate over two lists simultaneously in form which is
simple (.html), do not described in models.py or admin.py

## views.py
obj1=mod1.filter(field__contains='smth1').order('-date')
obj2=mod2.filter(field__contains='smth2').order('-date')

return render_to_response('filter_obj.html', {'List1':obj1, 'List2':
obj2, 'q': query })

## filter_obj.html

{% if List1 %}
{%  for smth1, smth2 in List1, List2 %}

 how to iterate here ?

I did not understand what was the a reason, but i changed order of
items in admin.py fields to be similar to items order in the model.
Maybe mistake was some mistyping. Anyway error disappeared.

Re: form handling in views.py

[gintare]

Thanks a lot, i just wanted to know how to use variables from query
directly. If you could advice, please write me.

I read Django documentation on beginning of 2010 and understood only
now on 2011 where forms are used. I mean if smbd never programmed
webpages the use of templates and forms is totally unclear from
Documentation, afterwards it is very useful when one understands how
web-pages are generated from them (There could be some chapter for
beginners - full working example: model, view, templates, forms ).

form handling in views.py

[gintare]

Maybe smbd could give advice how data submitted from custom.html to
views.py are handled further?


   custom.html  with method  search1 ##

 
{% if Lp %}
{%  for item in Lp %}




 

  {{item.Word}}   

 
{{item.dateWord}}   





{% endfor %}
{% endif %}



   views.py  with method  search1 ##


def search1(request):
request.encoding='utf-8'
query = request.GET.get( 'q','')

The code above works when i have one button and one text area.

I do not understand
 how to find out which input was selected and
 how to read text from many text areas (how to relate several text
areas in row with single button in that row ) .

Re: to execute executable.py from view.py

[gintare]

One more related question.

Is it possible to use string in views.py as a function ( string from
textarea (in search.html ))

i.e.
# search.html

 input function name 



this search.html after being registered in urls.py shows input text
area.
I prompt to write the name of function.

I get this name as string in views.py in function def
search2(request):
query=request.GET.get('q',' ' )
i would like now to run this function, which was written in textarea,
 i.e to run function Word.objects.all()

One of ways is to use Sqlite cursor and execute strings.
Another way is to use case type structure, which match function name
in string with function name in cases.

How to run this function, which was written in textarea as string,
without sqlite and case structures?

return render_to_response("my_fnc.html", { " FindWord" :
FindWord } )

[code]

Gives error Manager isn't accessible via FindWord instances

I would like to get result of quesry in separate function.
How to return this result to initial function in view or print it to

ImproperlyConfigured: 'SentAdmin.fields' refers to field 'dateSent' that is missing from the form.

[gintare]

I was changing models many times and deleting tables inbetween.
New tables were generated to improved models and admin site worked
perfectly.
Now smth happened that i am getting error:

ImproperlyConfigured: 'SentAdmin.fields' refers to field 'dateSent'
that is missing from the form.

'dateSent' is in the model and correctly described in admin.py

I did not added this field before generating new tables. It was
previously.
If i comment other fields gives the same error.

What can be the solution?
Should i make new project or there is a way to update forms (for
field 'dateSent' and orher fields that are missing from the form
according Django) ??

Re: automatic addition of several ForeignKeys to model

[gintare]

Thanks.

The thing which i wanted must be done in forms. It is not for models
and database.

I mean there must be function in views.py which checks if some item
already exists in database and add information about this item
(item.pk) to another synonim item.

I do not understnad to which file i have to add custom functions for
admin.


2) How to add a button to Admin (i.e. submit_line.html), which
pressing would call function defined in views.py.

I would like to add "custom functions related to button in

[gintare]

Hello,

I would like to add ForeignKey which would ass many items to class as
much i append-create-give.


class word1(models.Model):
item=models.CharField(blank=True)

class word2(models.Model):
itemSynonims=models.ForeignKey(word1)

Re: windows7, django-admin.py, system variables, no module named django.core

[gintare]

Hello,

I mean the correct way of running django seems to be to add to windows
environmental variable PATH c:/first/Python26/Lib/site-packages/
Django-1.2.1/django/bin
and when run
$ cmd
$ django-admin.py startproject mysite

the question, why importing management from django.core do not work?
from django.core import management
Error: No module django.core

the module is under c:/first/Python26/Lib/site-packages/Django-1.2.1/
django
I mean it seems cmd must know where are all django modules. How?

Re: windows7, django-admin.py, system variables, no module named django.core

[gintare]

Thanks a lot!
Would like to clearify how i should run python from command line:

1)
cmd
#in command line shell under windows
cd c:/first/Pyhton26
#change to directory with pyhton executable
python   #
to start python environment in comman line shell
>>>>import sys
>>>>sys.path 
>>>>#prints  C:\first\Python26\Lib\site-packages as one of paths
>>>>django-admin.py syncdb   # ERROR -   name 
>>>>'django' is not defined


OR

2)
cmd
#in command line shell under windows
cd c:/first/Pyhton26
#change to directory with pyhton executable

pyhton django-admin.py syncdb#also ERROR: 'can
not open file django-admin.py'

pyhton django-admin syncdb#also ERROR: 'can
not open file django-admin'

django-admin.py syncdb#also ERROR: 'no module
named django.core'

django-admin syncdb#also ERROR: 'django-admin
is not recogmized as internal or external command'

The idea is that both "python executable"  and "django/bin/ with
django-admin.py" are in system path.
Should i put only pyhton on systme path?

3)
 I have several different pyhton installations. How cmd can recognize
python command if they all are under system path?
Does it first look in current working directory: I.e. if i start from
c:/fisrt/python26 it will not run python from c:/second/python31?

[gintare]

I am not able to run django under windows7

I tried to write them in browsers input field in several ways:

 models.CharField(max_length=500, blank=True, default='').

for i in range(len(Ltitles)): stLtit=stLtit

[gintare]

Hello,

Is it possible in python access name of variable?
I want to convert the name of the variable to the string, not the
value of variable to the string.

For example for item inclass  Aref: List.append( str(name_of _item) )
i want 'Rfirstauthor' to be inserted in List[0], not the value of
variable Rfirstauthor = 'John Smith'

models.py

class Aref(models.Model):
Rfirstauthor=models.CharField(max_length=500, blank=True,
default='')
.

thanks,
gintare

Sqlite3, saving many items simultaneosly

[gintare]

Hello,

Is it possible to pack name of the column and value before submitting
to the database.
I mean something to save( dictionary), where dictionaries key is the
name of column and dictionaries item is value to be saved) or
save(list_column_names, list_values)?

b = Blog(  [name, tagline] , ['Beatles Blog', 'All the latest Beatles
news]  )
>>> b.save()


I do not want to call save(column_name, item_value) for every item
separately, i.e.:
b = Blog(name='Beatles Blog', tagline='All the latest Beatles news.')
>>> b.save()

My database consist of 20 columns.
Now i am using Sqlite3 syntax, where i print all column and item
names  to one string.

regards,
gintare

what has to be changed after project.db deletion and new empty project.db file creation manually

[gintare]

Hello.

to summarize the question is

which lines has to be changed when the database file i.e, referenc.db
is deleted and later created manually as empty database?

The problem is that i created whole project a week before.
 Later i modified modules, added new tables and new fields (Rrest
column was added for sure in table Areferenc_aref).
 I deleted empty database file referenc.db, created new database file
referenc.db manually expecting that new tables will be generated with
additional fields for hem.

Nevertheless the django finds only old columns.

besides i made one check:

1) first of all i totally deleted referenc.db again. For big surprise
command manage.py syncdb runs without mistakes.

Besides python manage.py sql Areferenc  generates tables for non
existing database.

^Cworking:/opt/pages/referenc# python manage.py sql Areferenc

BEGIN;
CREATE TABLE "Areferenc_aref" (
"id" integer NOT NULL PRIMARY KEY,
"Rfirstauthor" varchar(500) NOT NULL,
 "Rauthors" varchar(500) NOT NULL,
"Rjournal" varchar(500) NOT NULL,
"Rrest" varchar(500) NOT NULL,
"Rpage" varchar(500) NOT NULL,
"Rissue" integer NOT NULL,
 "Rvolume" integer NOT NULL,
"Ryear" integer NOT NULL,
"Rtitle" varchar(500) NOT NULL,
"Rkeyw" varchar(500) NOT NULL,
"Rurl" varchar(200) NOT NULL,
 "Rindex" varchar(500) NOT NULL,
"Rname" varchar(500) NOT NULL,
"Rdoi" varchar(500) NOT NULL,
"Rlink" varchar(100) NOT NULL,
"Rmail" varchar(75) NOT NULL,
 "Rconcl" text NOT NULL,
"Rexists" bool NOT NULL,
"Rinst" varchar(500) NOT NULL
)
;
CREATE TABLE "Areferenc_experimental" (
"id" integer NOT NULL PRIMARY KEY,
 "Rexp" varchar(500) NOT NULL
)
;
CREATE TABLE "Areferenc_characterization" (
"id" integer NOT NULL PRIMARY KEY,
"Rchar" varchar(500) NOT NULL
)
;
 CREATE TABLE "Areferenc_devices" (
"id" integer NOT NULL PRIMARY KEY,
"Rdev" varchar(500) NOT NULL
)
;
CREATE TABLE "Areferenc_calculations" (
"id" integer NOT NULL PRIMARY KEY,
 "Rcal" varchar(500) NOT NULL
)
;
CREATE TABLE "Areferenc_afieldorder" (
"id" integer NOT NULL PRIMARY KEY,
"Rorder" varchar(500) NOT NULL
)
;
CREATE TABLE "Areferenc_aref_Rexperimental" (
 "id" integer NOT NULL PRIMARY KEY,
"aref_id" integer NOT NULL REFERENCES "Areferenc_aref" ("id"),
"experimental_id" integer NOT NULL REFERENCES
"Areferenc_experimental" ("id"),
 UNIQUE ("aref_id", "experimental_id")
)
;
CREATE TABLE "Areferenc_aref_Rcharacterization" (
"id" integer NOT NULL PRIMARY KEY,
"aref_id" integer NOT NULL REFERENCES "Areferenc_aref" ("id"),
 "characterization_id" integer NOT NULL REFERENCES
"Areferenc_characterization" ("id"),
UNIQUE ("aref_id", "characterization_id")
)
;
CREATE TABLE "Areferenc_aref_Rdevice" (
 "id" integer NOT NULL PRIMARY KEY,
"aref_id" integer NOT NULL REFERENCES "Areferenc_aref" ("id"),
"devices_id" integer NOT NULL REFERENCES
"Areferenc_devices" ("id"),
 UNIQUE ("aref_id", "devices_id")
)
;
CREATE TABLE "Areferenc_aref_Rcalculation" (
"id" integer NOT NULL PRIMARY KEY,
"aref_id" integer NOT NULL REFERENCES "Areferenc_aref" ("id"),
 "calculations_id" integer NOT NULL REFERENCES
"Areferenc_calculations" ("id"),
UNIQUE ("aref_id", "calculations_id")
)
;
COMMIT

2) Secondly I created referenc.db in  ./referenc manually again.

generated tables with command mentioned in step1 with the same output
(table Areferenc_aref contains column Rrest )

performed manage.py syncdb, which went fluently without mistakes.

executing view i am getting error:

Exception Type:
OperationalError
  Exception Value:
table Areferenc_aref has no column named Rrest
  Exception Location:

2) Secondly I created referenc.db in  ./referenc manually again.

generated tables with command mentioned in step1 with the same output (table
Areferenc_aref contains column Rrest )

performed manage.py syncdb, which went fluently without mistakes.

executing view i am getting error:

mouse events and view.py

[gintare]

How correctly define syntax for the event in templates?

I want that all text in the text area
would be send to the python function "search2"
after i paste text or click mouse.
After making changes the text has to be pasted back to the same form.

Is it possible with python or i need java script?

Bellow is view.py and diction.html which do not work,
 i.e. line:   " print "search2", search2, query "
do not print in terminal words which i pasted to the text area.

##diction.html


  
 

##views.py
def search2(request):
query = request.GET.get('Lpasted', '')
print "search2", search2, query
t=get_template(Tdiction.html)
html=t.render( Context({'Lpasted':sentenc}) )
return HttpResponse(html)

What is the name of view, in which folder.

My question was:

if you could paste code of any example it would be grate.

simple, input from user and database earch result

[gintare]

Hello,

One more simple question:

Is it possible that area which is used for data submission also can be
updated from python script.

How in *.html describe that input can be both
from the user
and a result of some script.


 1   

On line 1 user put a word
On line 2 user start search in database
I would like to get the result of the search printed back in the same
field on the line 1.

gintare

django_evolution evolve not found

[gintare]

I have installed django_evolution from Debian package.
It is now under /usr/lib/pyhton2.5/site-packages/django_evolution

i also added :
 ln -s `pwd` /django-trunk/django   /usr/lib/python2.5/site-packages/
django_evolution

But the command 'evolve' is not recognized.
I.e. i am in project "links" directory and try to run evolution in
several ways, i.e.:
python manage.py evolve --hint
evolve.py --hint
evolve

none of do work.

Is it possible to get working version of package similar to evolution.
Or maybe it is possible somehow correct this installation or give
additional command line parameters.

gintare

how relate webpage with databse in my harddisk?

[gintare]

Hello,

Sorry for a simple question.

How other can access pages i generated with django?
How others could be able to fill forms and get data from my hard disk
through generated html interface?

I am connecting and filling database by myself in folder  /mano/
mysite1.
I would like to connect to generated html pages through internet from
remote computer, fill questionaries and leave or get data to/from
database.
