• How do I use a ListProperty(users.user) in a djangoforms.ModelForm on Google AppEngine?

  - by Gabriel

  I have been looking around a bit for info on how to do this. Essentially I have a Model: class SharableUserAsset(db.Model): name = StringProperty() users = ListProperty(users.User) My questions are: What is the best way to associate users to this value where they are not authenticated, visa vi invite from contacts list etc.? Is there a reasonable way to present a list control easily in a djangoforms.ModelForm? Once a user logs in I want to be able to check if that user is in the list for any number of SharableUserAsset class "records", how do I do that? Does user evaluate as a match to an email address or is there a way to look up a valid user against an email address?

• Iterating over key and value of defaultdict dictionaries

  - by gf

  The following works as expected: d = [(1,2), (3,4)] for k,v in d: print "%s - %s" % (str(k), str(v)) But this fails: d = collections.defaultdict(int) d[1] = 2 d[3] = 4 for k,v in d: print "%s - %s" % (str(k), str(v)) With: Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'int' object is not iterable Why? How can i fix it?

• Run shell script using fabric and piping script text to shell's stdin

  - by Peter Lyons

  Is there a way to execute a multi-line shell script by piping it to the remote shell's standard input in fabric? Or must I always write it to the remote filesystem, then run it, then delete it? I like sending to stdin as it avoids the temporary file. If there's no fabric API (and it seems like there is not based on my research), presumably I can just use the ssh module directly. Basically I wish fabric.api.run was not limited to a 1-line command that gets passed to the shell as a command line argument, but instead would take a full multi-line script and write it to the remote shell's standard input.

• Polynomial fitting with log log plot

  - by viral parekh

  I have a simple problem to fit a straight line on log-log scale. My code is, data=loadtxt(filename) xdata=data[:,0] ydata=data[:,1] polycoeffs = scipy.polyfit(xdata, ydata, 1) yfit = scipy.polyval(polycoeffs, xdata) pylab.plot(xdata, ydata, 'k.') pylab.plot(xdata, yfit, 'r-') Now I need to plot fit line on log scale so I just change x and y axis, ax.set_yscale('log') ax.set_xscale('log') then its not plotting correct fit line. So how can I change fit function (in log scale) so that it can plot fit line on log-log scale? Thanks -Viral

• How to create a backup from SqlAlchemy?

  - by swilliams

  I'm writing a Pylons app, and am trying to create a simple backup system where every table is serialized and tarred up into a single file for an administrator to download, and use to restore the app should something bad happen. I can serialize my table data just fine using the SqlAlchemy serializer, and I can deserialize it fine as well, but I can't figure out how to commit those changes back to the database. In order to serialize my data I am doing this: from myproject.model.meta import Session from sqlalchemy.ext.serializer import loads, dumps q = Session.query(MyTable) serialized_data = dumps(q.all()) In order to test things out, I go ahead and truncation MyTable, and then attempt to restore using serialized_data: from myproject.model import meta restore_q = loads(serialized_data, meta.metadata, Session) This doesn't seem to do anything... I've tried calling a Session.commit after the fact, individually walking through all the objects in restore_q and adding them, but nothing seems to work. What am I missing? Or is there a better way to do what I'm aiming for? I don't want to shell out and directly touch the database, since SqlAlchemy supports different database engines.

• Non-global middleware in Django

  - by hekevintran

  In Django there is a settings file that defines the middleware to be run on each request. This middleware setting is global. Is there a way to specify a set of middleware on a per-view basis? I want to have specific urls use a set of middleware different from the global set.

• Allowing users to delete their own comments in Django

  - by RaDeuX

  I am using the delete() function from django.contrib.comments.views.moderation module. The staff-member is allowed to delete ANY comment posts, which is completely fine. However, I would also like to give registered non-staff members the privilege to delete their OWN comment posts, and their OWN only. How can I accomplish this?

• Getting an entry before and after a given entry in a Django Queryset

  - by Vernon

  I am creating a simple blog as part of a website and I am getting stuck on something that I am assuming is simple. If I call any blog post, say by it's title, from a queryset, how can I get the entry before and after the post in it's published order. I can iterate over the whole thing, get the position of the entry I have and use that to call the one before and the one after. But that is a long bit of code for something that I am sure I can do more simply. What I want would be something like this: next_post = Posts.object.filter(title=current_title).order_by("-published")[-1] Of course because of the filter, it is not going to work, but just to give you the idea of what I am looking for.

• Intersection of two querysets in django

  - by unagimiyagi

  Hello, I can't do an AND on two querysets. As in, q1 & q2. I get the empty set and I do not know why. I have tested this with the simplest cases. I am using django 1.1.1 I have basically objects like this: item1 name="Joe" color = "blue" item2 name="Jim" color = "blue" color = "white" item3 name="John" color = "red" color = "white" Is there something weird about having a many-to-many relationship or what am I missing? queryset1 = Item.objects.filter(color="blue") this gives (item1, item2) queryset2 = Item.objects.filter(color="white") this gives (item2, item3) queryset1 & queryset2 gives me the empty set [] The OR operator works fine (I'm using "|" ) Why is this so?

• Facebook Connect via Javascript doesn't close and doesn't pass session id

  - by ensnare

  I'm trying to authenticate users via Facebook Connect using a custom Javascript button: <form> <input type="button" value="Connect with Facebook" onclick="window.open('http://www.facebook.com/login.php?api_key=XXXXX&extern=1&fbconnect=1&req_perms=publish_stream,email&return_session=0&v=1.0&next=http%3A%2F%2Fwww.example.com%2Fxd_receiver.htm&fb_connect=1&cancel_url=http%3A%2F%2Fwww.example.com%2Fregister%2Fcancel', '_blank', 'top=442,width=480,height=460,resizable=yes', true)" onlogin='window.location="/register/step2"' /> </form> I am able to authenticate users. However after authentication, the popup window just stays open and the main window is not directed anywhere. In fact, it is the popup window that goes to "/register/step2" How can I get the login window to close as expected, and to pass the facebook session id to /register/step2? Thanks!

• how to detect an escape sequence in a string

  - by mix

  Given a string named line whose raw version has this value: \rRAWSTRING how can I detect if it has the escape character \r? What I've tried is: if repr(line).startswith('\r'): blah... but it doesn't catch it. I also tried find, such as: if repr(line).find('\r') != -1: blah doesn't work either. What am I missing? thx! EDIT: thanks for all the replies and the corrections re terminolgy and sorry for the confusion. OK, if i do this print repr(line) then what it prints is: '\rSET ENABLE ACK\n' (including the single quotes). i have tried all the suggestions, including: line.startswith(r'\r') line.startswith('\\r') each of which returns False. also tried: line.find(r'\r') line.find('\\r') each of which returns -1

• Chipmunk warning still present with --release

  - by Kaliber64

  I'm using Python27 on Windows 7 64-bit. I downloaded the source for Chipmunk 6.2.x and compiled Pymunk with --release and -c ming32. Almost zero problems. Lots of path not found cause I'm bad. All prints seem to have disappeared but I get spammed with EPA iteration warnings. I've seen a couple discussions but no solutions. Possible chipmunk betas to fix the float errors causing the double truths causing the warning. I picked the latest stable version I think. My program is seriously bogged down with all the prints. class NullDevice(): def write(self, s): pass sys.stdout=NullDevice() Does not disable the C prints .< Any help?

• How to preprocess a Django model field value before return?

  - by Satoru.Logic

  Hi, all. I have a Note model class like this: class Note(models.Model): author = models.ForeignKey(User, related_name='notes') content = NoteContentField(max_length=256) NoteContentField is a custom sub-class of CharField that override the to_python method in purpose of doing some twitter-text-conversion processing. class NoteContentField(models.CharField): __metaclass__ = models.SubfieldBase def to_python(self, value): value = super(NoteContentField, self).to_python(value) from ..utils import linkify return mark_safe(linkify(value)) However, this doesn't work. When I save a Note object like this: note = Note(author=request.use, content=form.cleaned_data['content']) The conversed value is saved into the database, which is not what I wanna see. Would you please tell me what's wrong with this? Thanks in advance.

• Reducing size of a character array in Numpy

  - by Morgoth

  Given a character array: In [21]: x = np.array(['a ','bb ','cccc ']) One can remove the whitespace using: In [22]: np.char.strip(x) Out[22]: array(['a', 'bb', 'cccc'], dtype='|S8') but is there a way to also shrink the width of the column to the minimum required size, in the above case |S4?
