  • Pylons paginator question

    - by Timmy
    Only comments associated with the current page should be listed, so once again the query is modified to include the page ID. In this case, though, we also have to pass the pageid argument, which will in turn get passed to any h.url_for() calls in the paginator. from http://pylonsbook.com/en/1.1/simplesite-tutorial-part-2.html i cannot get this to work, the paginator does not pass things to the h.url_for, i followed the tutorial. i had to add pageid to the h.url_for in list.html. how do i solve? part of the code: ${h.link_to( comment.id, h.url_for( controller=u'comment', action='view', id=unicode(comment.id) ) )} but it does not work properly until i put in ${h.link_to( comment.id, h.url_for( controller=u'comment', action='view', id=unicode(comment.id), pageid = c.page.id ) )}

  • Preventing referenced assembly PDB and XML files copied to output

    - by Jason Morse
    I have a Visual Studio 2008 C#/.NET 3.5 project with a post build task to ZIP the contents. However I'm finding that I'm also getting the referenced assemblies' .pdb (debug) and .xml (documentation) files in my output directory (and ZIP). For example, if MyProject.csproj references YourAssembly.dll and there are YourAssembly.xml and YourAssembly.pdb files in the same directory as the DLL they will show up in my output directory (and ZIP). I can exclude *.pdb when ZIP'ing but I cannot blanket exclude the *.xml files as I have deployment files with the same extension. Is there a way to prevent the project from copying referenced assembly PDB and XML files?

  • django sphinx automodule -- basics

    - by haras.pl
    Hi, I have a projects with several large apps and where settings and apps files are split. directory structure goes something like that: project_name __init__.py apps __init__.py app1 app2 3rdparty __init__.py lib1 lib2 settings __init__.py installed_apps.py path.py templates.py locale.py ... urls.py every app is like that __init__.py admin __init__.py file1.py file2.py models __init__.py model1.py model2.py tests __init__.py test1.py test2.py views __init__.py view1.py view2.py urls.py how to use a sphinx to autogenerate documentation for that? I want something like that for each in settings module or INSTALLED_APPS (not starting with django.* or 3rdparty.*) give me a auto documentation output based on docstring and autogen documentation and run tests before git commit btw. I tried doing .rst files by hand with .. automodule:: module_name :members: but is sucks for such a big project, and it does not works for settings Is there an autogen method or something? I am not tied to sphinx, is there a better solution for my problem?

  • Django: name of many to many items in the admin interface

    - by Adam
    I have a many to many field, which I'm displaying in the django admin panel. When I add multiple items, they all come up as "ASGGroup object" in the display selector. Instead, I want them to come up as whatever the ASGGroup.name field is set to. How do I do this? My models looks like: class Thing(Model): read_groups = ManyToManyField('ASGGroup', related_name="thing_read", blank=True) class ASGGroup(Model): name = CharField(max_length=63, null=True) But what I'm seeing the m2m widget display is:

  • Repetitive content in docstrings

    - by Morgoth
    What are good ways to deal with repetitive content in docstrings? I have many functions that take 'standard' arguments, which have to be explained in the docstring, but it would be nice to write the relevant parts of the docstring only once, as this would be much easier to maintain and update. I naively tried the following: arg_a = "a: a very common argument" def test(a): ''' Arguments: %s ''' % arg_a pass But this does not work, because when I do help(test) I don't see the docstring. Is there a good way to do this?

  • File Uploads with Turbogears 2

    - by William Chambers
    I've been trying to work out the 'best practices' way to manage file uploads with Turbogears 2 and have thus far not really found any examples. I've figured out a way to actually upload the file, but I'm not sure how reliable it us. Also, what would be a good way to get the uploaded files name? file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, file.filename.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = self.request.params["file"].filename permanent_file.close() So assuming I'm understanding correctly, would something like this avoid the core 'naming' problem? id = UUID. file = request.POST['file'] permanent_file = open(os.path.join(asset_dirname, id.lstrip(os.sep)), 'w') shutil.copyfileobj(file.file, permanent_file) file.file.close() this_file = file.filename permanent_file.close()

  • how to handle an asymptote/discontinuity with Matplotlib

    - by Geddes
    Hello all. Firstly - thanks again for all your help. Sorry not to have accepted the responses to my previous questions as I did not know how the system worked (thanks to Mark for pointing that out!). I have since been back and gratefully acknowledged the kind help I have received. My question: when plotting a graph with a discontinuity/asymptote/singularity/whatever, is there any automatic way to prevent Matplotlib from 'joining the dots' across the 'break'? (please see code/image below). I read that Sage has a [detect_poles] facility that looked good, but I really want it to work with Matplotlib. Thanks and best wishes, Geddes import matplotlib.pyplot as plt import numpy as np from sympy import sympify, lambdify from sympy.abc import x fig = plt.figure(1) ax = fig.add_subplot(111) # set up axis ax.spines['left'].set_position('zero') ax.spines['right'].set_color('none') ax.spines['bottom'].set_position('zero') ax.spines['top'].set_color('none') ax.xaxis.set_ticks_position('bottom') ax.yaxis.set_ticks_position('left') # setup x and y ranges and precision xx = np.arange(-0.5,5.5,0.01) # draw my curve myfunction=sympify(1/(x-2)) mylambdifiedfunction=lambdify(x,myfunction,'numpy') ax.plot(xx, mylambdifiedfunction(xx),zorder=100,linewidth=3,color='red') #set bounds ax.set_xbound(-1,6) ax.set_ybound(-4,4) plt.show()

  • What did I lose when I upgraded?

    - by Richard
    I upgraded my work box from Vista64 to Win7-64 by doing a format and reinstall. I kept backups of the project done in MS Visual Studio 2008 (Team). But now it won't compile. I am getting errors generated on lines in the MS created header files like "'_In_' not defined" etc. I know it is because I lost some compiler setting/directive. I was sure that the compiler settings would be in the project file; now I see that things like the include file directories, LIB files, etc. are not. [FYI: The project is a VB.NET GUI with VC++ DLL talking to a PIC24 micro over USB.] How do I most efficiently get my project back on the road to execution?

  • Scipy sparse... arrays?

    - by spitzanator
    Hey, folks. So, I'm doing some Kmeans classification using numpy arrays that are quite sparse-- lots and lots of zeroes. I figured that I'd use scipy's 'sparse' package to reduce the storage overhead, but I'm a little confused about how to create arrays, not matrices. I've gone through this tutorial on how to create sparse matrices: http://www.scipy.org/SciPy_Tutorial#head-c60163f2fd2bab79edd94be43682414f18b90df7 To mimic an array, I just create a 1xN matrix, but as you may guess, Asp.dot(Bsp) doesn't quite work because you can't multiply two 1xN matrices. I'd have to transpose each array to Nx1, and that's pretty lame, since I'd be doing it for every dot-product calculation. Next up, I tried to create an NxN matrix where column 1 == row 1 (such that you can multiply two matrices and just take the top-left corner as the dot product), but that turned out to be really inefficient. I'd love to use scipy's sparse package as a magic replacement for numpy's array(), but as yet, I'm not really sure what to do. Any advice? Thank you very much!

  • Uploading file from file object with PyCurl

    - by Tom
    I'm attempting to upload a file like this: import pycurl c = pycurl.Curl() values = [ ("name", "tom"), ("image", (pycurl.FORM_FILE, "tom.png")) ] c.setopt(c.URL, "http://upload.com/submit") c.setopt(c.HTTPPOST, values) c.perform() c.close() This works fine. However, this only works if the file is local. If I was to fetch the image such that: import urllib2 resp = urllib2.urlopen("http://upload.com/people/tom.png") How would I pass resp.fp as a file object instead of writing it to a file and passing the filename? Is this possible?

  • Header file-name as argument

    - by Alphaneo
    Objective: I have a list of header files (about 50 of them), And each header-file has few arrays with constant elements. I need to write a program to count the elements of the array. And create some other form of output (which will be used by the hardware group). My solution: I included all the 50 odd files and wrote an application. And then I dumped all the elements of the array into the specified format. My environment: Visual Studio V6, Windows XP My problem: Each time there is a new set of Header files, I am now changing the VC++ project settings to point to the new set of header files, and then rebuild. My question: A bit in-sane though, Is there any way to mention the header from some command line arguments or something? I just want to avoid re-compiling the source every time...

  • TVirtualStringTree - resetting non-visual nodes and memory comsumption

    - by Remy Lebeau - TeamB
    I have an app that loads records from a binary log file and displays them in a virtual TListView. There are potentially millions of records in a file, and the display can be filtered by the user, so I do not load all of the records in memory at one time, and the ListView item indexes are not a 1-to-1 relation with the file record offsets (List item 1 may be file record 100, for instance). I use the ListView's OnDataHint event to load records for just the items the ListView is actually interested in. As the user scrolls around, the range specified by OnDataHint changes, allowing me to free records that are not in the new range, and allocate new records as needed. This works fine, speed is tolerable, and the memory footprint is very low. I am currently evaluating TVirtualStringTree as a replacement for the TListView, mainly because I want to add the ability to expand/collapse records that span multiple lines (I can fudge it with the TListView by incrementing/decrementing the item count dynamically, but this is not as straight forward as using a real tree). For the most part, I have been able to port the TListView logic and have everything work as I need. I notice that TVirtualStringTree's virtual paridigm is vastly different, though. It does not have the same kind of OnDataHint functionality that TListView does (I can use the OnScroll event to fake it, which allows my memory buffer logic to continue working), and I can use the OnInitializeNode event to associate nodes with records that are allocated. However, once a tree node is initialized, it sees that it remains initialized for the lifetime of the tree. That is not good for me. As the user scrolls around and I remove records from memory, I need to reset those non-visual nodes without removing them from the tree completely, or losing their expand/collapse states. When the user scrolls them back into view, I can re-allocate the records and re-initialize the nodes. Basically, I want to make TVirtualStringTree act as much like TListView as possible, as far as its virtualization is concerned. I have seen that TVirtualStringTree has a ResetNode() method, but I encounter various errors whenever I try to use it. I must be using it wrong. I also thought of just storing a data pointer inside each node to my record buffers, and I allocate and free memory, update those pointers accordingly. The end effect does not work so well, either. Worse, my largest test log file has ~5 million records in it. If I initialize the TVirtualStringTree with that many nodes at one time (when the log display is unfiltered), the tree's internal overhead for its nodes takes up a whopping 260MB of memory (without any records being allocated yet). Whereas with the TListView, loading the same log file and all the memory logic behind it, I can get away with using just a few MBs. Any ideas?

  • Getting a RichTextCtrl's default font size in wxPython

    - by Sam
    I have a RichTextCtrl, which I've modified to accept HTML input. The HTML parsing code needs to be able to increase and decrease the font size as it gets tags like <font size="-1">, but I can't work out how to get the control's default font size to adjust. I tried the following (where self is my RichTextCtrl): fred = wx.richtext.RichTextAttr() self.GetStyle(0,fred) print fred.GetFontSize() However, the final instruction fails, because GetStyle turns fred into a TextAttrEx and so I get AttributeError: 'TextAttrEx' object has no attribute 'GetFontSize'. Am I missing a vastly easier way of getting the default font size?

  • Sizers... - wxPython

The problem is that I can't align Loginform and Image separately (im using Box Sizers), and I would like to. This is the code I'm using that is causing the problem at the moment, any help is appreciated. NOTE:The code might be (HUGELY) sloppy as I'm still learning box sizers. sizer = wx.BoxSizer(wx.VERTICAL) sizer1 = wx.BoxSizer(wx.HORIZONTAL) sizer1.Add(self.nb,1, wx.EXPAND) sizer.Add(sizer1,1, wx.LEFT | wx.RIGHT | wx.EXPAND, 10) sizer.Add((-1, 25)) sizer2 = wx.BoxSizer(wx.VERTICAL) sizer2.Add(self.userLabel, 0) sizer2.Add(self.userText, 0) sizer2.Add(self.pwdLabel, 0) sizer2.Add(self.pwdText, 0) sizer2.Add(self.rem, 0) sizer3 = wx.BoxSizer(wx.HORIZONTAL) sizer3.Add(self.login, 0) sizer3.Add(self.sair,0, wx.LEFT, 5) sizer2.Add(sizer3, 0) sizer4 = wx.BoxSizer(wx.HORIZONTAL) sizer4.Add(image, 1, wx.LEFT | wx.BOTTOM) sizer4.Add(sizer2,0, wx.RIGHT | wx.BOTTOM , 5) sizer.Add(sizer4,0, wx.ALIGN_RIGHT | wx.RIGHT, 10)

  • How to customize pickle for django model objects

    - by muudscope
    I need to pickle a complex object that refers to django model objects. The standard pickling process stores a denormalized object in the pickle. So if the object changes on the database between pickling and unpickling, the model is now out of date. (I know this is true with in-memory objects too, but the pickling is a convenient time to address it.) So what I'd like is a way to not pickle the full django model object. Instead just store its class and id, and re-fetch the contents from the database on load. Can I specify a custom pickle method for this class? I'm happy to write a wrapper class around the django model to handle the lazy fetching from db, if there's a way to do the pickling.

  • Open/Close database connection in django

    I am using Django and Postgresql as my DBMS. I wish to set a setting that enables to enable/disable database connection. When the connection is set to closed (in settings.py) the site will display a message such as "meintanence mode" or something like that. Django will not show any db connection error message (or mail them to admins). It is appreciated if django do not try to connect to the database at all.
