Re: wondering how to do something similar to save_model for inline.
Good call on the ModelAdmin spot. (user contacted me by email to see if I had a solution yet.) I got the formset.save() from here: http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#the-save-method saying: "If your formset contains a ManyToManyField, you'll also need to call formset.save_m2m() to ensure the many-to-many relationships are saved properly." Works now just had it in the wrong spot. thx! On Jan 6, 9:23 pm, "Karen Tracey" wrote: > On Tue, Jan 6, 2009 at 10:10 PM, Timboy wrote: > > > Still no solution to this.

Re: Import models from CSV files?

That's explained in whole details in the online documentation. Go to djangoproject.com, click the "documentation" link, then follow the "models : accessing related objects" link. If i was one of Django's doc writer, I'd probably start to despair.

Django internal tests and url reverse lookup
Hi all, If I run manage.py test form my project, Django internal test are executed as well. If such a internal test uses a RequestContext, all template context processors defined in settings.TEMPLATE_CONTEXT_PROCESSORS are loaded by django.template.context.get_standard_processors(). If one of this (custom) template context processors uses "django.core.urlresolvers.reverse()" for a reverse URL matching, there will be no match for project specific URLs as this URL definitions aren't loaded for Django internal tests. How can this be fixed? Shouldn't load the test environment all the project URL definitions?

Drop down list not seeing newly added record
I have a 2 forms. One to add a new author and then another form for Articles which has a drop down list to reference the authors. The behavior I am seeing is that when I add a new author and then go to the New Article form which references the author it does not display the new record. Also, I put in some print statements in the New Article form class and those statements are only executed when I go to my home page. Here are my code snippets def welcome(request): print 'in welcome' if request.GET: if request.GET.has_key( 'newarticle'): print 'going to new article' return HttpResponseRedirect( '/melsite/newarticle') if request.GET.has_key( 'newauthor'): print 'going to new author' return HttpResponseRedirect( '/melsite/newauthor') else: print 'retrieving articles' articles = Article.objects.filter (type_index__type='Poem').order_by('title') return render_to_response('stories/welcome.html', {'title': 'Poems', 'articles': articles}) def newarticle( request): print 'in new article request' from storyforms import NewArticle if request.method == 'POST': print 'in new article post' new_data = request.POST.copy() articleform = NewArticle(new_data) if form.is_valid(): form.save( new_data) articles = Article.objects.filter (type_index__type='Poem').order_by('title') return render_to_response('stories/welcome.html', {'title': 'Poems', 'articles': articles}) else: print 'in setting up new article' #from storyforms import NewArticle articleform = NewArticle() print 'after setting up new article' print 'rendering article' return render_to_response('stories/add_story.html', {'form': articleform}) class NewArticle( forms.Form): articletypelist=[] authorlist = [] print 'in new article class' articletypes = ArticleType.objects.all().order_by( 'type') articletypelist.append( selecttuple) for articletype in articletypes: choicestr = "choice%s" % str( articletype.id) typetuple = choicestr, articletype.type articletypelist.append( typetuple) authors = Author.objects.all().order_by( 'last_name') print 'authors in new article are ', authors authorlist.append( selecttuple) for author in authors: choicestr = "choice%s" % str( author.id) authorname = author.first_name + ' ' + author.last_name authortuple = choicestr, authorname authorlist.append( authortuple) ArticleType = forms.ChoiceField( choices=articletypelist) Author = forms.ChoiceField( choices=authorlist) Title = forms.CharField() Content = forms.CharField( widget=forms.Textarea) print 'end of new article def' Thanks, Jeff --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Your IDE of choice
I have omnicomplete working (haven't used it too much yet). I have this in my $HOME/.vimrc file: --.vimrc-- if has("autocmd") autocmd BufRead *.py set smartindent \ cinwords=if,elif,else,for,while,try,except,finally,def,class autocmd FileType python set omnifunc=pythoncomplete#Complete autocmd FileType javascript set omnifunc=javascriptcomplete#CompleteJS autocmd FileType html set omnifunc=htmlcomplete#CompleteTags autocmd FileType css set omnifunc=csscomplete#CompleteCSS endif " Allow to be used instead of like other IDE's do " for auto-completion inoremap --.vimrc-- All 'autocmd' lines should be single lines. Also, I have vim starting automatically importing the Django db. I have a little script (below) that will automatically find my settings.py file and start vim. I do this by starting at the location of the file on the vim command line and working upwards in the directory structure until I find it: --dvim-- #!/packages/bin/python """ Start vim for Django files """ import os import sys args = sys.argv # Get our starting directory to look for the settings file.

Process file after upload
Hey. I have FielField in my model for user to upload ZIP-archives. I want to unpack that zip, place some files in some dirs and delete it just after user uploaded it in admin. How can i do this? Model's save won't work because it gets called everytime model is saved regardless of were the file uploaded again or not.

I just tried GEdit and failed
I just tried GEdit on the basis of this thread to replace a very good but slow Komodo. GEdit is not good, or should I say, the plugins that let it be a python dev environment are not good. Perhaps I've selected and incompatible set of plugins, because they started off working somewhat decently, then syntax coloring was wrong for some files as though it was detecting the wrong language and the class browser turned blank, A lot of the plugins don't look like they've been touched in a few years so maybe they're unmaintained. Could someone post a list of of GEdit plugins that create a good django environment? Komodo Edit is very good except it's too slow.

A common way to check if an object is getting saved for the first time or not is to check if it has a pk. A newly created object won't have a pk until you call the super save() method, so you can put whatever operations you want to conduct inside an "if not obj.pk:" block.

Re: I just tried GEdit and failed
Right now I use Gedit as my text editor(I don't use the terminal plugin, I just keep a seperate terminal up), that being said here are the plugins I use: * class browser * code comment * file browser pane * indent lines * Python indentation * smart spaces * snippets depending on what your looking for I believe that there is a current in development plugin to add auto completion.

Problems with locale of dates queryset
Hi! I'm trying to display a list of possible months in a queryset. I do so like this: premonths = MyModel.objects.dates('date_published', 'month') months = [m.strftime('%B') for m in premonths] The problem is that months get displayed in english instead of spanish, which is what I want. I have the following setting in my settings file, but it does not seem to do what I want: LANGUAGE_CODE = 'es-ES' I can indeed work out a solution doing something like this: premonths = MyModel.objects.dates('date_published', 'month') import locale locale.setlocale(locale.LC_TIME, "sp") months = [m.strftime('%B') for m in premonths] But I guess I'm missing something here... BTW, the problem of the wrong locale of dates is everywhere I use dates on my site, not only in this snippet.

Re: Import models from CSV files?
Hey Victor, I did the django-batchimport mentioned earlier. I think it will address your need but is definitely aimed at XLS. However, it does already handle duplicates (it will either update them or ignore them based on setting). You can also specify a subset of model fields to use to determine whether a given row represents a duplicate. This allows for "batch update" too. If you get into it and have any problems, drop me a note.

Re: Django: creating formset is very slow
Hi, I was able to solve it. The issue was not with formsets, nor database. It was slow because request.POST was getting delayed - ranging from 3.5 seconds to 3+ minutes. I even tried having an assignment as follows: x = request.POST and even that was taking 3seconds to 3 minutes. On going through the depths of wsgi code (yay, opensource), I found the parsing is much slower in case on multipart messages - and I had my http content-type and encoding as multipart. Since having files was a rare thing in my code, I modified the code to encode as basic encoding unless files was present. Now, the same code - with 500 elements - take 0.7 seconds instead of the earlier 117 seconds. Open source is amazing.

This is standard Python behavior. If you need to depend on data that may change between the time the form class is loaded and a form instance is created, you need to put the logic that retrieves and uses that data into an __init__ function. The __init__ function will get called each time a NewArticle form instance is created, rather than just once when the NewArticle code is imported/loaded.

I use null=False, blank=True for some ImageFields and integers. In both cases, I am generated the this content for the database, but it is not entered. In the case of the ImageField, an image is uploaded (an original), then I generate a thumbnail, and a viewable (a standard sized image). Technically at this point I don't need blank=True here because users only upload the original image, but at some point I can allow them to upload an optional thumbnail and then use that if supplied or generate it if not. In the case of an integer, I use it for order of the images. So if a number is given for an image, it is used, otherwise auto assign the order number. I thought this was a common use case with Django. So that is a -1 for me.

I would like to do the same in the fiedsets option of ModelAdmin, but I get an error saying my method is missing from the form when the page is rendered. It seems to me I can only render model methods with list_display and not the fiedsets. Any tips to get this working? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Authorlist and articletypelist are much better implemented as class methods on the relevant models: class Author(models.Model): ... @classmethod def get_authorlist(cls): return [('choice%s' % a.id, '%s %s' % (a.first_name, a.last_name)) for a in cls.objects.all().order_by('last_name')] Then in your view or template you can do Author.get_authorlist() to return the up-to-date list. However, a much better solution is to use ModelChoiceField for the Articletype and Author fields. These populate the list dynamically from a queryset: class NewArticle(forms.Form): ... Author = forms.ModelChoiceField(queryset=Author.objects.order_by ('last_name')) -- DR. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Adding link to Django book Search code
Hello, I would like to change the view so that the link retrieves more of the detailed information from the same model publication, but I haven't figured out how to change the view to respond either to a new search and/or to more detailed information about the item found. The link can go to a new page or refresh on the current search.html page. See http://dpaste.com/106410/ for the html and the view. The URL is: urlpatterns = patterns('mysite.fsafety.views.', (r'^$', 'index'), (r'^search/$', 'search'), ) Thank you for any help.

Re: Using a model method in ModelAdmin fieldsets
What I try to achieve: I have a couple of model methods that exposes real time information. (Retrieved when method is called.) This is information I want to display not only in the list_display, but also within the change view. (Where the fieldsets come into play). Since the list_display option support methods call I was wondering how I can expose this information within the change view without too much changing the default code. I think the problem is that the change view builds up a form from the model and method calls can not be updated. The reason why not included in the form object ..and therefor not visible to the fieldsets field? Still clear as mud?

Since you can't edit/change something that is the result of a model method, I don't believe there are any hooks for showing these thing on the change page. If I were to try to do this (which I haven't, so no guarantees that this is even the right approach) I'd probably start by looking at overriding/extending the template used for the change view for that model: http://docs.djangoproject.com/en/dev/ref/contrib/admin/#overriding-admin-templates Karen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

How to impose a permission-based filter in admin?
Hi, I have two Model classes: class Opportunity(models.Model): rep = models.ForeignKey(User) ... class Deal(models.Model): opportunity = models.ForeignKey(Opportunity) ... I want to limit the admin UI so that users can only see Opportunities and the related Deals they own. If they attempt to go into the Deal table directly, again, they should only see their Deals. To make it more interesting: Some users (that have a special permission) should be able to see ALL Opportunities and Deals. How can I do this?

Re: Using a model method in ModelAdmin fieldsets
Thanks Karen & Daniel, I think your overiding approach will work. Thank you. Implemented a work around.

The models define how things are to be setup and stored in the database backend. A blank value in a webpage does not translate to a blank value in the database, so blank=True is incorrect in this case, as an auto-assigned value isn't actually blank, because a non-blank value will be stored in the database.

Customizing form fields display
Can anyone suggest a way to customize model field display? For example if I have a model called Course with fields n_girls and n_students, if for a particular record n_girls = 4 and n_students = 10, I want to display for n_girls: "40% (4)" instead of just "4". Obviously I can do this in the template but there are multiple fields I want to customize and the lack of switch/elsif statement in the templates would make for a deeply nested structure so I'd rather do it upstream in the model.

It doesn't say anything about what's stored in the database, that's what null is for. They're decoupled, which allows for setting blank=True,null=False and substituting a non-blank auto-generated value at some point after form validation but before saving the model. It may not be an approach you prefer, but that does not make it incorrect. Karen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: lighttpd + django on windows
In fact, I think that the chapter describing the fastcgi deployment in the django doc is a little ... light :-) it gives only a description of a typical django.fcgi, and that's all. I have already deployed django sites with the following configs: - fastcgi ona hosting platform - apache/mod_python - standalone and there was no problem.

"submit" and urls.py fail after moving site from runserver to Apache
Hi, I followed the django tutorial and got my site running on runserver + sqlite3 with no problems I then moved the site onto apache + mod_python and (after receiving some help from this group) managed to get the same site semi-running The admin page, home page, and a few others are working as they were with runserver... but I now have a strange problem with one of my pages I have a submit input on one of my pages and when I run the site on runserver it still works fine (I just tried it now) However, when I run the exact same site on Apache the url that is returned by "submit" is different, and this obviously causes the pattern matching in urls.py to fail Here is the html + template script that causes the problem {% if error_message %}{{ error_message }}{% endif %} {% for entry in entry_list %} {{ entry.eng_val }} {% endfor %} With runserver it returns the following when I press submit: "http://127.0.0.1:8000/swenglish/test/submit/"; With Apache it returns the followingwhen I press submit: "http://localhost/swenglish/test/submit/?thank +you=tack&much=mycket&he=han&fun=roligt&bye=hej+da&snow=sno" Any help would be greatly appreciated!

Revise "search code" in Django Book
Hello, I am using the search code from the Django Book to search a publication table (model). The results are placed on the search.html page. I want to drill down and send more detail from the link that now surrounds each of the search results. I would like that detail information to go to another page search_detail.html. The ID from the first search is associated with each publication link and that ID should be able to retrieve the same information as the original search, but let me expand on the info for one publication on a new page. I need assistance on either revising the original search function in the view or fixing the search_detail function instead. The code is here: http://dpaste.com/106510/.Can anyone help?

Textmate with Python/Django bundles is very visually nice, but without code completion (and a few other tools) is just a pretty screen.

The files do not reside under our site's document root, because my boss does not want them there (for reasons that aren't entirely clear to me). Also, we want to do some extra processing before the file is served, e.g. increment an integer representing the number of downloads. Thirdly, we want to be able to force the browser to download the file instead of displaying it (in the case of PDFs, for example). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

(sorry, hit the send button to soon) Else, you could eventually just pass the file object itself to HttpResponse: http://docs.djangoproject.com/en/dev/ref/request-response/#passing-iterators ... but I don't know if you will gain that much from doing so (wild guess: this probably depends on how you deploy your django instance).

Re: Import models from CSV files?
heya, The sample code request was just me being lazy =). Hmm, so you think the csv parsing code should be in the upload processing? This would just be a form with two boxes for the user to select the .csv files, and an upload button. Better putting it here than in the model? In terms of processing, well, there's only a little bit. One of the files is a dump from a Lotus Notes view. It looks a little like this DateRegion Arrival TimeDurationSites For 2008-12-1 Australia 7:30 AM - 1.25 [HR] /SYD/225 G John Smith /GER/115 A Nolan Smith 7:30 AM - 1.25 [HR] /SYD/225 G Bob Smith 7:30 AM - 1.25 [HR] /SYD/225 G Joe Smith NZ 7:30 AM - 1.25 [HR] /SYD/225 G Jane Smith /SYD/ 7:30 AM - 1.0 [HR] /SYD/225 G Mary Smith 7:30 AM - 5.0 [HR] /SYD/225 G Brown Smith 2008-12-2 NZ 7:30 AM - 1.25 [HR] /SYD/225 G Jane Smith /SYD/ 7:30 AM - 1.25 [HR] /SYD/225 G Mary Smith 7:30 AM - 1.25 [HR] /SYD/225 G Brown Smith Firstly, there were dropdowns (e.g. for Date, and Region) - those date and regions apply to the rows below them - annoying, but easy to deal with. Also, the time is given as a start time and duration - I converted this into a start_time and end_time. Finally, the Sites and For columns can each contain multiple entries. After parsing, I'm storing it as a list of users, each with a list of access periods granted (containing the start_time, end_time and site - and a few other things). So you go through, and create entries for each user, for each of the sites, per line. Not too bad. Heck, I'll just post the code (I'm halfway through working on it - may not compile cleanly right now, but you get the idea). http://dl.getdropbox.com/u/281283/access_requests.py I guess the important thing is just the users being able to upload the .csv files themselves, and dealing with weirdness in the input.

Re: what type of data structure should I use?
There's no need to keep selecting from the DB and refreshing the page. You can re-sort the list client-side on AJAX response (with jQuery, for instance). The tablesorter plugin (http://tablesorter.com/docs/) is not exactly what you're looking for but will give you an idea of how to sort client-side, if you're not sure. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

At a minimum, what is the output of groupmembers.query.as_sql() There may be a problem with exclude and nested querysets. I just realised I haven't explicitly tested those.

Write some model methods that return the appropriate string format of the given field. Or write some filters that accept a model object as the input value and format it appropriately. Using template filters for presentation changes always feels pretty natural to me. Model methods work, but, as noted above, my inclination is always to use models as the presentation-agnostic data object and set things up so that I can control presentation indepedently of the data itself.

URL pattern matching in Django doesn't look at the hostname portion of the URL or the query string (everything after the "?"). So those two URLs should look exactly the same to Django. When you have DEBUG=True in your settings file, do you really get the 404 screen saying it couldn't match any URL patterns? If so, what pattern does it say it was trying to match? It looks like something is going wrong in the runserver case, by the way. Your form is submitted using a GET action, which means the submitted URL should look like the second case (although the hostname portion might well be different). It's not clear why you're using GET and not POST there, by the way -- better to use normal form processing practice -- which means action="post", not action="get" -- when you're starting out so that the differences don't make things any harder than they already are.

Not, that's a NULL value. Blank has absolutely no technical meaning at the database level and certainly not any kind of ambiguous one. That's just confusing the issue. You're correct that Django uses it as a data-entry-level term meaning that the field was left blank, but wishing/hoping that it also substitutes as NULL isn't making things any clearer. As far as I'm concerned, this issue kind of died when somebody pointed out the binary field case. That's a minimally valid example of why the separation makes sense still.

Some people would like it to create automatically, others prefer it to be explicit. I'm in the latter camp: if a user should have a profile, I should create it properly when creating the user (e.g. using a signal), not have some magical transparency happen behind the curtain that hides the bug of me forgetting to do so. After all, if you're creating a profile, you might well need to initialise it in some particular default way. So now get_profile() needs to be like get_or_create() and accept a bunch of default arguments. Much more complicated. It's a moot point, though. Changing it would introduce the sort of backwards incompatibility we try to avoid.

Re: what type of data structure should I use?
Thanks for the link. I like that. I'm going to see if I can use it. I'd like to be able to do one query, then bring it into this plugin, sort it 3 or 4 different ways on the client side. I haven't really had any time today to look at it. But, I also thought about trying some kind of session object to hold the data. I could possibly use it to work with the jQuery plugin.

You can't really do that at the moment. You're talking about what we call the "application" name, and that's taken from the Python name. You could write a custom template for the admin interface that hard-codes what you're after. Copying the existing template and putting in an "if" template tag to test if the name's the one you want to override. So it's not necessarily impossible and I've seen it done, but you have to really want to do it.

Admin | Lookup via foreign key | Expected Behavior or Bug?
I'm not certain if this is a bug, or expected behavior. It certainly looks like a Django bug to me. However, after looking at the same database for hours on end, it could simply be a cross-eyed user error.In sort, the admin interface has the following search fields (I know this won't scale very well and is cumbersome. Unfortunately, it's the fields my customer wants to search; I also know that the first_service, second_service, etc. models breaks 2nd normal form however, again, it is my customer's preference =( ). search_fields = ['contact_name', 'alternate_contact_name', 'cross_reference', 'client_reference', 'info', 'people_involved__first_name', 'people_involved__last_name', 'people_involved__info', 'case_notes__notes', 'first_service__service', 'second_service__service', 'third_service__service', 'fourth_service__service', 'first_subcontractor__subcontractor', 'second_subcontractor__subcontractor', 'third_subcontractor__subcontractor', 'fourth_subcontractor__subcontractor' ]If you look at the following link, you'll see two 'cases': http://barbados.thepythonshoppe.com/forensic/admin/forensic_database/case/userid: adminpassword admin(this is a development instance for testing)If you notice in case 1, you'll notice that 'indigo' is a 'Person Involved' first name set up for testing. However, it is not found during a search. In summary, the following search fields work perfectly:* 'contact_name'* 'alternate_contact_name'* 'cross_reference'* 'client_reference'* 'info'While the remainders do not. Either I am not properly using the syntax of 'model, double underscore, field' to refer to the foreign model, I've made another mistake (or am missing a key piece of information), or this is a legitimate bug (i.e., foreign key lookups do not work).Any help you can give would be great. Then I would know that I need to go read something to learn from a mistake, or I need to break this down into a test case for a bug reproduction.I've tested this against the latest trunk with the same results.The admin.py file is attached.Thanks in advance,Glen Jarvis --415-680-3964g...@glenjarvis.comhttp://www.glenjarvis.com"You must be the change you wish to see in the world." -M.

Setting Bound Fields Programmatically
I have a form with the following fields (all required): - first_name - last_name - site_id I'd like to use a template to display only the FIRST two items to the user for him to fill out: {{ form.first_name }} {{ form.last_name }} Then when it gets posted back to me I'd like to set the site_id based on a session variable or whatever like this (from my view): if request.method == 'POST': my_data = {'site_id':1234} my_data.update(request.POST) form = form_class(data=my_data, files=request.FILES) if form.is_valid(): process form here... My problem is that I cannot get the form to validate. It keeps telling me that site_id is not set. How can I programmatically set this one form field's value and have the user set the others without sending through a hidden field yada yada. Please help! Thank you.

Not only do you not want it to be required, but you do not even want to display it? So why it is there? Putting it there and then trying to fake out as though valid data had been posted for it just seems like a backwards approach to whatever real problem you are trying to solve.

It keeps telling > me that site_id is not set. On the surface, that look like it should work. Which makes me suspect some important detail has been lost in the simplification. What does the my_data dictionary look like just before you execute the "form = ..." line (print it out)? Also, how is form_class specified? Finally, what is the exact error Django gives you? Print out form._errors, for example. Maybe somewhere in there the answer will jump out. Admittedly, all the clues may already be there and I'm just missing the obvious, but I can't see it right now. On a related note, is there any particular reason you need to have site_id in the form class at all? Even if it's a model form, you could exclude it, and add it into the model object later, couldn't you? You might be going about this slightly backwards by trying to force in site_id when it's not something that actually needs to be validated or form-processed.

Is it from DB access? XML generation? If it's from DB access, include the code you're using to fetch data. If XML generation, likewise. -- --- David Zhou da...@nodnod.net --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

So I have no idea what is going wrong in your case. I'd try simplifying search fields to a single one that is not currently working. If you specify that one, does it work? If not, check the SQL generated by the admin (either turn on query logging at the database or use something like the debug toolbar) for clues as to why the search isn't working. If the one field does work, add fields one at at time until it breaks, and see what sort of clues you get then, and from the SQL generated then, etc. Karen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
