Re: form_for_model + FileField issue
Malcolm,
I wasn't very clear in my question. Sorry about that.
It took a bit of trial and error but I found a hack that works the way I
want it to. I use the model and form_for_model/form_for_instance for all
fields except the file uploads. For the file uploads I use FileInput(). That
was what I meant by '... I could leave the FileFields out of the model and
use a form class for those fields instead.'
I you have any suggestions on how to secure/improve/validate this please let
me know.
Thanks,
Vincent

Re: tutorial 4, generic views won't load from db?
Thanks, it worked!
It was my fault to ingore the paragraph about change the variables
names. Maybe if there were modified codes in the page, it will be
better, because codes are much easier to discover.

Handling Very Large File Uploads and Cookie-less Visitors
Hello, Regarding very large file uploads, I know this probably gets asked a lot and I've found one thread that comes close to what the answer I'm looking for: http://groups.google.com/group/django-users/browse_thread/thread/ca95963aaa33ce1e/c69fb3381885f9a7 This thread was posted about a year ago and I cannot find any follow-ups to this discussion. I am running Django using mod_python and my question is: What happens when a very large file is uploaded? Does it all get stored in memory or is it stored in a temp file and accessed as a byte stream? I want to be able to allow very large file uploads but I want to make sure an upload does not use up all the memory on the machine. Regarding cookie-less visitors or visitors with cookies disabled on their browser or proxy. Django, with the SessionMiddleware, will always create a new session and send a new session id as a cookie to the browser. Even with just the HEAD script from libwww-perl, I am able to get the site to issue new sessions with every HEAD request. What happens if a script kiddie hammers the site with so many HEAD requests? Do dead/unused sessions pile up on the sessions table? Does Django do anything to mitigate this or at least clean up dead/unused sessions automatically? -- _nimrod_a_abing_ http://abing.gotdns.com/ http://www.preownedcar.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Noob here. Accessing data across relationships
I think that requires more logic in the template than possible.
My brain says tot do exactly what you suggest. But my template looks
similar to this:
{% for p in object.events.all %}
{{ p.event_name }},
{% endfor %}
If the Member isn't registered to one of the events, then I don't get
a for that event, and it throws off the rest of the format
for the table...

I just quickly perused your email; if the only problem you are having is
the loop creating the table row/column when there isn't any actual data,
couldn't you just create an {% if object %} in the template, and adjust

Upload Image Example - Is anything busted with my example?
I am a Django newbie and had a lot of trouble figuring out how to
upload an image. I looked at lots of examples of which no single one
made it clear how to do this. After much effort I came up with
something that works and at least I find to be clear so I wanted to
post it for other newbies to use and for the pros to tell me if I did
anything terribly wrong. I spent some effort trying to comment it well
and also tried to name things uniquely so you know what is what.
Hopefully this will save others time. Oh yeah I'll insert the
obligatory Django Rocks here. Looking forward to version 1.0
(hopefully with full support for form_from_model to avoid this whole
upload issue)
Oh and as a favor to others If you do correct this please be very
explicit about where corrections are made and what is new, and what is
replaced and where these should go. Even better copy what I have here
and edit that directly so there is a complete example to look at.

Your questions don't really make sense. There is no FileField in newforms yet. The current admin interface does not use newforms, so it isn't pertinent to the issue. Do not get model fields and form fields confused, since they are entirely different objects serving different purposes. You certainly cannot chop and change them.

Django itself does not implement any locking features, or anything else designed to manage database concurrency. That's the job of your database -- so long as you're in a transaction you should get a consistent view of the data the whole time you're working with it, and good databases let you configure them to deal with concurrent data changes (e.g., with PostgreSQL you can set transactions to "serializable", and concurrent write attempts from two processes will result in one of them getting an exception saying that the data changed elsewhere). -- "Bureaucrat Conrad, you are technically correct -- the best kind of correct." --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Just using it normally -- using a gettext_lazy proxy object wherever you
would normally use a format string -- will do what you expect.
s = gettext_lazy('my string %s %d')
...
print s % ('fred', 11)
The only thing to consider is to make sure that you don't actually do
the interpolation too early -- since that converts it from a proxy to a
string -- so the translation has to take place at that moment. All this
means is don't do interpolation at import time, for example. Doing it
inside views or anything called from a view should be fine, though,
since the correct locale will already be in effect.

God's Simple Plan of Salvation
God's Simple Plan of SalvationMy Friend: I am asking you the most important question of life. Your joy or your sorrow for all eternity depends upon your answer. The question is: Are you saved? It is not a question of how good you are, nor if you are a church member, but are you saved? Are you sure you will go to Heaven when you die? God says in order to go to Heaven, you must be born again. In John 3:7, Jesus said to Nicodemus, "Ye must be born again." In the Bible God gives us the plan of how to be born again which means to be saved. His plan is simple! You can be saved today. How? First, my friend, you must realize you are a sinner. "For all have sinned, and come short of the glory of God" (Romans 3:23). Because you are a sinner, you are condemned to death. "For the wages [payment] of sin is death" (Romans 6:23). This includes eternal separation from God in Hell. " . . . it is appointed unto men once to die, but after this the judgment" (Hebrews 9:27). But God loved you so much He gave His only begotten Son, Jesus, to bear your sin and die in your place. " . . . He hath made Him [Jesus, Who knew no sin] to be sin for us . . . that we might be made the righteousness of God in Him" (2 Corinthians 5:21). Jesus had to shed His blood and die. "For the life of the flesh is in the blood" (Lev. 17:11). " . . . without shedding of blood is no remission [pardon]" (Hebrews 9:22). " . . . God commendeth His love toward us, in that, while we were yet sinners, Christ died for us" (Romans 5:8). Although we cannot understand how, God said my sins and your sins were laid upon Jesus and He died in our place. He became our substitute. It is true. God cannot lie. My friend, "God . . . commandeth all men everywhere to repent" (Acts 17:30). This repentance is a change of mind that agrees with God that one is a sinner, and also agrees with what Jesus did for us on the Cross. In Acts 16:30-31, the Philippian jailer asked Paul and Silas: " . . . 'Sirs, what must I do to be saved?' And they said, 'Believe on the Lord Jesus Christ, and thou shalt be saved . . . .' " Simply believe on Him as the one who bore your sin, died in your place, was buried, and whom God resurrected. His resurrection powerfully assures that the believer can claim everlasting life when Jesus is received as Savior. "But as many as received Him, to them gave He power to become the sons of God, even to them that believe on His name" (John 1:12). "For whosoever shall call upon the name of the Lord shall be saved." (Romans 10:13). Whosoever includes you. Shall be saved means not maybe, nor can, but shall be saved. Surely, you realize you are a sinner. Right now, wherever you are, repenting, lift your heart to God in prayer. In Luke 18:13, the sinner prayed: "God be merciful to me a sinner." Just pray: "Oh God, I know I am a sinner. I believe Jesus was my substitute when He died on the Cross. I believe His shed blood, death, burial, and resurrection were for me. I now receive Him as my Savior. I thank You for the forgiveness of my sins, the gift of salvation and everlasting life, because of Your merciful grace. Amen." Just take God at His word and claim His salvation by faith. Believe, and you will be saved. No church, no lodge, no good works can save you. Remember, God does the saving. All of it! God's simple plan of salvation is: You are a sinner. Therefore, unless you believe on Jesus Who died in your place, you will spend eternity in Hell. If you believe on Him as your crucified, buried, and risen Savior, you receive forgiveness for all of your sins and His gift of eternal salvation by faith. You say, "Surely, it cannot be that simple." Yes, that simple! It is scriptural. It is God's plan. My friend, believe on Jesus and receive Him as Savior today. If His plan is not perfectly clear, read this tract over and over, without laying it down, until you understand it. Your soul is worth more than all the world. "For what shall it profit a man, if he shall gain the whole world and lose his own soul?" (Mark 8:36). Be sure you are saved. If you lose your soul, you miss Heaven and lose all. Please! Let God save you this very moment. God's power will save you, keep you saved, and enable you to live a victorious Christian life. "There hath no temptation taken you but such as is common to man: but God is faithful, Who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it" (1 Corinthians 10:13). Do not trust your feelings. They change. Stand on God's promises. They never change. After you are saved, there are three things to practice daily for spiritual growth:· Pray -- you talk to God. · Read your Bible -- God talks to you. · Witness -- you talk for God. You should be baptized in obedience to the Lord Jesus Christ as a public testimony of your salvation, and then unite with a Bible- believing church without delay. "Be not thou therefore ashamed of the testimony of our Lord . . .
Database protection/coherency between multiple applications accessing the same tables
Hi, in the past I've written to this list re using the django db back-end as a db access layer for a test-automation system I work on; we hope to re-write the current front-end with django at some point. We're a little closer to experimenting with this, and have another question: is there any coherency checking/row (table?) locking implemented in django's db layer? i.e. if I have two scripts, on two different machines, both accessing the same db & table, what built in support is there to catch race-conditions/invalid updates/etc? Are there any examples out there someone can point me to? Also, is there any difference with which db is used- MySql vs Postgres? So far we've found nothing by searching; I suspect we're using the wrong terminology... (Background: We are hoping to re-write the front-end web-gui in Django (current one is difficult to maintain, and hard for new developers), and as the backend (scheduler, always running) is in python and has an 'interesting'- i.e. slightly broken- db layer, we're thinking to fix to problems by taking advantage of django.)

You cannot do this at the moment. It might appear in the future, though.
However, it looks like you might be able to get the same effect using a
values queryset (using the .values() method in the query) and leaving
out the pk field from the fields you want to retrieve. In that case, the
distinct() filter will not be thrown off by the varying pk values. (I'm
not in a position to be able to test this at the moment, but it looks
correct from eye-balling the code).
Alternatively, custom SQL is always possible.

Malcolm

This is more a data typing issue, than the fact that it is a foreign key. If you have a ForeignKey pointing to a primary key in the remote table that is a string, then you could use startswith (can't remember if we've fixed the bug that makes the foreign key have the right type in that case or not, but it should be possible). > > I am building a dynamic form where the users can select the field and > the type of lookup to filter a query. > Using newforms I do: > > >>> self.fields["comparison"] = forms.ChoiceField() > >>> self.fields["comparison"].choices = ([(i,i) for i in > >>> models.query.QUERY_TERMS]) > > The problem here is that the user can select any lookup type, not only > the valid ones. > I would like that each model class Field define a list of valid > options. I look the code and it looks like it is not possible. In practice, we don't need such a list. Maintaining such a list of restrictions would be fairly time consuming (and mistakes would be made). Some cases are backend dependent. In practice, the callers will use sensible search terms and we raise an error if they don't because the database detects the problem. If you wanted to build one by hand, the list of possible query terms is in django/db/models/query.py. Go through that list and for each data type, create a short list of search terms that aren't applicable (creating a blacklist is going to be easier than a whitelist).

SELECT, DELETE and UPDATE privileges on the tables associated with all your models. So, any tables starting with your app names (myapp_* sort of patterns), plus SELECT permission on the django_user_* tables (if you are never going to add new users) and SELECT, DELETE and UPDATE on the session table. If you are using the admin interface, pretty much all the django_* tables will need DELETE/UPDATE permissions on them, otherwise you might be able to get away without needing access to those. There might be a few small things missing, but that should be pretty close. Basically, all models need read permissions on their respective tables. If you are creating new instances of a model, you need update and delete permissions. Nothing outside of syncdb (in Django itself) needs CREATE or DROP permissions.

Whilst it's an annoying problem, I don't think this is a solution. We've talked about this a couple of times in the past (in particular, adding it to startapp and startproject). The problem is that it only solves the relatively small problem of initial creation and whatever happens to be visible at that moment. It doesn't add any robustness against installing third-party apps later (when you realise you actually need them) or moving from a development system to production or setting your Python import path in a different way so that now an entirely different set of names are visible. A solution like this stands a good chance of causing more pain than benefit, because people will rely on it too much at the start and then get bitten when the venture into the real world. Avoiding clashes with other modules on your Python path is something you always have to do in Python. Django doesn't feel like the right level to be trying to solve it (and every other language that allows inclusion of other units of code).

It could be implemented as a sub-query ... There is nothing in Django that does sub-queries (yet) and now is not the right time to be hacking up special cases like this. Remember that limit and offset are entirely non-relational operations, so, in part, the way we act the way we do in QuerySets is a consequence of this leaky abstraction (leaking up from SQL). Once you apply a limit/offset restriction to the result sequence, you cannot apply further relational operations to it. The *only* thing you can do is use it in a sub-query and that isn't particularly good SQL construction in any case (almost always there are better ways to get the same result with better performance characteristics). Once query construction is moved into it's own class, people who want to do strange and unusual things like this will be able to go crazy, sub-classing query construction, using queries as parameters to other queries -- the whole enchilada with extra beans.

Noob here. Accessing data across relationships
I'm having trouble pulling/formatting data into my template. I have added some Event items into the database. For the example, we'll say "golfing", "hiking" and "swimming". In my template, using the generic object_list, I want to list each member's information (easy enough) and then each event_name they've been assigned to (my problem). I can easily pull up a list of the events they're added to: (inside the template: a quick for loop over object.events.all) The trouble I'm having is, if someone is not assigned to an event, I get nothing displayed (duh, there's not an event); except I'm displaying this in a table, and if I don't have any data, then the cell formatting doesn't line up correctly. So! My thought process was to do part of the work myself in the view. But now I'm not sure where to go from here, and I'm not even sure how to ask the right questions (which is probably the whole of my problem as I'm sure I'm not the only one who has ever done this). What I get right now is similar to, in csv format (first line is hard coded into the template): name, address, conference id, golfing, hiking, swimming Justin, 1200 K St., 40, golfing swimming [note golfing swimming is one field] What I want in my output is a table (or csv) that reads like: name, address, conference id, golfing, hiking, swimming Justin, 1200 K St., 40, golfing, , swimming Here are my Models.simplified: class Conference(models.Model): conf_id = models.AutoField(primary_key=True) title = models.CharField(maxlength=100, core=True) class Event(models.Model): conference = models.ForeignKey(Conference)) event_name = models.CharField(maxlength=100, core=True) class Member(models.Model): name = models.CharField(maxlength=20) address = models.CharField(maxlenght=100) conferences = models.ManyToManyField(Conference) events = models.ManyToManyField(Event) class Admin: list_filter = ['events','conferences',] --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

form_for_model + FileField issue
Hi,
I have a form linked to a model. I am using form_for_model or
form_for_instance as required.
The only issue is that FileField fields are not displayed with a 'browse'
button. The function I am using is given below.
I know from the documentation that model fields get converted to form fields
by form_for_model (e.g., FileField to CharField).
But I want a FileField in my form :) Is there a way around this? Or another
way to create the form linked to the model that does not use form_for_model
or form_for_instance?
Thanks,
Vincent
def submit(request):
try:
inst = Application.objects.get(user=request.user)

form = ApplicationForm(request.POST)
if form.is_valid():
form.cleaned_data

Deduping a queryset based on one field
I have a Searchlog model, and I'm trying to build a queryset of all
unique searches ('searchstr' field). Using distinct() doesn't seem to
work because the pk will always be different. Ideally, I'd like to
use distinct() in a way where I could pass it the field I want to be
unique, such as:
queryset = SearchLog.objects.order_by('-date').distinct('searchstr')
Is there anything like this? I've seen a few discussions about
handling unique queryset results at the db/model level (such as for
many-to-many "tags"), by using the "unique=True" in the model
declaration. That won't work because I want to allow duplicate search
queries for other types of stats we're trying to keep (such as most
popular searches).
I'm wondering if this problem is something I can solve with a series
of queryset API calls, custom SQL, or maybe something I need to solve
with Python?
Thanks in advance,
Andy

Valid Lookup types by Model Field type
Hello, Can I dynamically determine what are the valid lookup types for a specified type of model field? i.e. If you try: >>> q1 = Entry.objects.filter(blog__startswith="What") where blog is a 'models.ForeignKey'. you will get an exception because "startswith" is not valid for ForeignKey fields. I am building a dynamic form where the users can select the field and the type of lookup to filter a query. Using newforms I do: >>> self.fields["comparison"] = forms.ChoiceField() >>> self.fields["comparison"].choices = ([(i,i) for i in >>> models.query.QUERY_TERMS]) The problem here is that the user can select any lookup type, not only the valid ones. I would like that each model class Field define a list of valid options. I look the code and it looks like it is not possible. Anyone tried this before?

Well, I finally have a more thorough characterization of the situation, as
illustrated here:

In [2]: all_loads = Load.objects.all()
In [3]: subset = all_loads[5:10]

Out[4]:

409 return self._clone(_order_by=field_names)
410

taken.
In [6]: for load in all_loads:
...: pass
...:
In [7]: subset = all_loads[5:10]
In [8]: type(subset)
Out[8]:
In [9]:
My original question, to some extent, has become irrelevent, since QuerySets
that are the progeny of slice operations are explicitly forbidden further
QuerySet-like processing (filter, order_by). That was my original desire.
However, I should point out that the sqlite3 backend should, IMO, always return
a QuerySet, independent of internal object caching.
However, am I crazy to wonder if filtering QuerySets with slices in their murky
past should be allowed? It could be implemented as a sub-query ...

This is a bit confusing.
I'd suggest

order_form = OrderForm(request.POST, prefix='orders')

if order_form.is_valid() and order_details_form.is_valid():

It seems like you're reading some tutorials on (old)forms and trying
to use newforms. They are two separate beasts, and should not be
combined - you don't need any of that FormWrapper stuff.
Side node: the IRC channel is useful for this sort of thing - dpaste
your model and then go ask about it there for quick help.

You thought about context processors not middleware processors, right?
It messed me for a while but now my code works. So thanks again, you
were very helpful.
Here is my solution (even two solutions)
The problem was: how to get access to 'request' from generic view's
template. I used the following generic view:
django.views.generic.list_detail.object_detail.
1. First solution requires us to modify urls.py
import django.core.context_processors
project_dict = {
'queryset': Project.objects.all(),
'context_processors': [django.core.context_processors.request] #
this is context_processor which enables request for our generic view
}
urlpatterns = patterns('',
(r'^projects/(?P\d+)/$',
'django.views.generic.list_detail.object_detail', project_dict),
)
2. Second solution is a global change for all generic views' templates
We must modify settings.py file and add there:
TEMPLATE_CONTEXT_PROCESSORS = (
"django.core.context_processors.auth",
"django.core.context_processors.debug",

Re: adding a drop down selection list

If you're really stuck, you need pointers as much as you need a solution; there really are many sources to find info on how to accomplish this fairly simple task. General steps: 1) add to html, which you've already done. 2) add to python view, which you've done wrong. 3) add to python model, which you probably haven't done. 3) add to database, which you probably haven't done. For #2, this line: sales_person = document.Submit.salespeople_dropdown.value most certainly should be something like this: sales_person = request.POST['salespeople_dropdown'] Based on this line: from django.models.accukeys import acculicenses you're using an old version of Django (pre-0.95), which is fine, but means you should refer to documents for the version you're using. I suggest this: http://www.djangoproject.com/documentation/0_91/ Anyway, for #3, go find the module accukeys.py, find the class in it named AccuLicense, and add a field attribute for sales_person. For #4, however you handle your DB migration, add the sales_person column to the DB; you should see mysql's docs for how to do that. If you are new to programming, rather than asking a broad question hoping for a very specific solution, consider contracting to get the job done or taking the time to learn the tools. We want to make Django easy to use, but even so, a fairly large amount of knowledge is assumed.

I don't need resizing of images in the bundle, and I don't like the idea of loading all the original images in the bundle to determine offsets in the final. Also, I'd like named bundles so that I could build multiple separate bundles at the same time rather than one big bundle for the page; I think this'd help me hit pre-made bundles more often. So, I plan on doing another implementation in the same vein. I see you're using mx.Misc.OrderedMapping.

Re: Saving POSTed Data
This is my view code for this implementation:
if request.method == 'POST':
form1 = form_for_model(Order)
Orders = form1(request.POST, prefix='orders')
form2 = form_for_model(Order_Detail)
Orders_Details = form2(request.POST, prefix='order_details')
if Orders.is_valid():
if Orders_Details.is_valid():
Orders.save()
Orders_Details.save()
return HttpResponseRedirect("/chef/")
else:
errors = new_data = {}
form = forms.FormWrapper(/*originally "manipulator" went here */,
new_data, errors)
^^
how do I pass back a form that includes both models? Something like:
form_a = form1.FormWrapper(form1, new_data, errors)
form_b = form2.FormWrapper(form2, new_data, errors)
return render_to_response('products/product_list.html', locals())
I've read the Django tutorials on this, but I am still confused. I'm
really eager to learn custom forms and to master it once and for all.
If anyone has a great tutorial for custom forms out there, please,
please let me know.
Greatly appreciated!

I've implemented a Jasper server in Jython. It listens on some network port and generates Jasper reports based on data incoming from socket. The data was sent by a Django application. This was work for hire, so I cannot share the sources. But it is really easy to use Jasper within Jython. And if it is possible to run Django under Jython, the task would become even simpler.

Good tip - thanks!
I have to admit, though, that I think adding a custom filter should be as simple
as this code alone:
> from django.template import Library
>
> register = Library()
>
> @register.filter
> def javadoc_filter(value, arg):
>return "whatever"
I think part of my confusion was that my subconscious thinking was "my filter
code has been imported (I can see the .pyc) so I know python has seen it, and
therefore the filter is registered with the library, so I should be able to use
it.".
This thinking does not reflect the current reality, and thats ok because I have
a workaround. But I think there is merit in a plain approach like that.
After all - Django is into the D.R.Y. principle, so having to use
register.filter() *as well* as have to have the module in a certain directory,
seems a bit repetitious.

Re: Jasper Reports
I inherited an online reporting/statistic web-app built with Spring and Jasper Reports. After being exposed to that, it is safe to say that I wont vulentarily use Jasper in any future project, ever. I haven't followed any of the links here, but iReport is a pretty horrible program to work with as well if you intend to export the reports to Excel. I'm building a reporting app myself in django as a replacement for the Spring thingy I mentioned above. My approach is to roll my own reporting; based on a query and an lot of various configurations, I build an XML file with the query result and all the parameteres. Then I have various command-line applications that I call 'exporters'. I pipe the XML into the exporter, which is able to convert it to anything, and pipe the exporters output back into a file that I put up for download. It sounds a lot like 'not-invented-here' mentality, but with the requirement to export to virtually anything, plus the existing application was a mess, this was the best way to do it that I could think of.
